(-)-Arctiin

C27H34O11 (534.2101014)

Natural compounds from herbs are recognized as an important source of therapeutic agents. Seeking for natural products with high selectivity and less side effects merits considerable efforts. Arctium lappa, also known as burdock, is widely consumed in East Asia, Europe and America to promote well-being for hundreds of years. In Chinese traditional medicine, Arctium lappa (mainly roots, and, to a less extend, seeds and leaves) is an important herbal medicinal preparation. It is commonly used for alleviating symptoms of inflammatory disorders, such as anemopyretic cold, cough, measles, urticaria and furuncle (Shin et al., 2015; Zhao et al., 2009). In addition, Arctium lappa is applied to treat various skin disorders including eczema and acne (Chan et al., 2011; Miglani and Manchanda, 2014). Lignans are the most characteristic phytoconstituents of Arctium lappa. Among them, ATG (Formula:C21H24O6; PubChem CID:64,981) and its glycoside, arctiin are the major bioactive compounds (Fig. 1). ATG, rich in roots and seeds of Arctium lappa, has attracted a great deal of attention due to its prominent therapeutic potential. It possesses many biological activities such as anti-oxidative stress (Lü et al., 2016), anti-cancer (He et al., 2018; Shabgah et al., 2021), anti-virus (Gao et al., 2018a) and anti-inflammation (Hyam et al., 2013; Zhao et al., 2009). Significant curative effects of ATG have been demonstrated on a wide range of human diseases including cancers, autoimmune disorders, chronic diseases, viral infections and other health concerns. The bioactivity of ATG largely depend on its chemical structure. For instance, the chiral carbon atom in the lactone ring is essential for the anti-tumor effect of ATG as (–)-arctigenin exhibits greater tumor suppression effect than (+)-arctigenin (Awale et al., 2014). Furthermore, the dibenzyl butyrolactone is key for the interactions between ATG and proteins. (-)-arctiin is a member of the class of compounds known as lignan glycosides. Lignan glycosides are aromatic polycyclic compounds containing a carbohydrate component glycosidically linked to a lignan moiety. They include 1-aryltetralin lactones (-)-arctiin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). (-)-arctiin can be found in burdock, which makes (-)-arctiin a potential biomarker for the consumption of this food product. Arctiin is a glycoside and a lignan.

Rosmarinic acid

C18H16O8 (360.0845136)

Rosmarinic acid is an ester of caffeic acid and 3,4-dihydroxyphenyllactic acid. It is commonly found in species of the Boraginaceae and the subfamily Nepetoideae of the Lamiaceae. It is a red-orange powder that is slightly soluble in water, but well soluble is most organic solvents. Rosmarinic acid is one of the polyphenolic substances contained in culinary herbs such as perilla (Perilla frutescens L.), rosemary (Rosmarinus officinalis L.), sage (Salvia officinalis L.), mint (Mentha arvense L.), and basil (Ocimum basilicum L.). These herbs are commonly grown in the garden as kitchen herbs, and while used to add flavor in cooking, are also known to have several potent physiological effects (PMID: 12482446, 15120569). BioTransformer predicts that rosmarinic acid is a product of methylrosmarinic acid metabolism via a hydrolysis-of-carboxylic-acid-ester-pattern1 reaction occurring in humans and human gut microbiota and catalyzed by the liver carboxylesterase 1 (P23141) enzyme (PMID: 30612223). (R)-rosmarinic acid is a stereoisomer of rosmarinic acid having (R)-configuration. It has a role as a plant metabolite and a geroprotector. It is a conjugate acid of a (R)-rosmarinate.

Epicatechin

C15H14O6 (290.0790344)

Epicatechin is an antioxidant flavonoid, occurring especially in woody plants as both (+)-catechin and (-)-epicatechin (cis) forms. Catechin is a tannin peculiar to green and white tea because the black tea oxidation process reduces catechins in black tea. Catechin is a powerful, water soluble polyphenol and antioxidant that is easily oxidized. Several thousand types are available in the plant world. As many as two thousand are known to have a flavon structure and are called flavonoids. Catechin is one of them. Green tea is manufactured from fresh, unfermented tea leaves; the oxidation of catechins is minimal, and hence they are able to serve as antioxidants. Researchers believe that catechin is effective because it easily sticks to proteins, blocking bacteria from adhering to cell walls and disrupting their ability to destroy them. Viruses have hooks on their surfaces and can attach to cell walls. The catechin in green tea prevents viruses from adhering and causing harm. Catechin reacts with toxins created by harmful bacteria (many of which belong to the protein family) and harmful metals such as lead, mercury, chrome, and cadmium. From its NMR espectra, there is a doubt on 2 and 3 atoms configuration. It seems to be that they are in trans position. Epicatechin, also known as (+)-cyanidanol-3 or 2,3-cis-epicatechin, is a member of the class of compounds known as catechins. Catechins are compounds containing a catechin moiety, which is a 3,4-dihydro-2-chromene-3,5.7-tiol. Thus, epicatechin is considered to be a flavonoid lipid molecule. Epicatechin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Epicatechin can be found in cashew nut, which makes epicatechin a potential biomarker for the consumption of this food product. Epicatechin can be found primarily in blood, feces, and urine, as well as throughout most human tissues. Epicatechin is a flavan-3-ol, a type of natural phenol and antioxidant. It is a plant secondary metabolite. It belongs to the group of flavan-3-ols (or simply flavanols), part of the chemical family of flavonoids . (-)-epicatechin is a catechin with (2R,3R)-configuration. It has a role as an antioxidant. It is a polyphenol and a catechin. It is an enantiomer of a (+)-epicatechin.

Carnosol

C20H26O4 (330.18309960000005)

Carnosol is a naturally occurring phenolic diterpene found in rosemary (Rosemarinus officinalis, Labiatae). It has been known that an extract of rosemary leaves contains high antioxidative activity. Ninety percent of this antioxidative activity can be attributed to carnosol and carnosic acid. Carnosic acid is easily converted to carnosol by oxidation. Carnosol has multiple beneficial medicinal effects including anti-inflammatory, anti-microbial and anti-cancer activities in various disease models. Carnosol may possess important neuroprotective effects against rotenone-induced DA neuronal damage. Naturally occurring antioxidants reduce the risk of neurodegenerative diseases. In addition, carnosol and carnosic acid promoted the synthesis of nerve growth factor in glial cells. Carnosol-mediated neuroprotection in DA neurons is involved in the attenuation of caspase-3 activity, which was induced by rotenone. Furthermore, carnosol-mediated tyrosine hydroxylase (TH) increase, which is dependent on the Raf-mitogen-activated protein kinase (MEK)-extracellular signal-regulated kinase (ERK)1/2 signaling pathway, is responsible for the neuroprotection in SN4741 DA cells. (PMID: 17047462). Carnosol, a phenolic diterpene compound of the labiate herbs rosemary and sage, is an activator of the human peroxisome proliferator-activated receptor gamma (PPARgamma), a ligand activated transcription factor, belonging to the metazoan family of nuclear hormone receptors. Activation of PPARgamma increases the transcription of enzymes involved in primary metabolism, leading to lower blood levels of fatty acids and glucose. Hence, PPARgamma represents the major target for the glitazone type of drugs currently being used clinically for the treatment of type 2 diabetes. (PMID: 16858665).

Phlorizin

C21H24O10 (436.1369404)

Phlorizin, also known as phlorizoside or phlorrhizen, belongs to the class of organic compounds known as flavonoid o-glycosides. Flavonoid O-glycosides are compounds containing a carbohydrate moiety which is O-glycosidically linked to the 2-phenylchromen-4-one flavonoid backbone. Phlorizin (also referred to as phloridzin; chemical name phloretin-2-‚âà√≠‚Äö√¢¬ß-D-glucopyranoside) is a glucoside of phloretin, a dihydrochalcone, a family of bicyclic flavonoids, which in turn is a subgroup in the diverse phenylpropanoid synthesis pathway in plants. In humans, phlorizin is involved in lactose degradation. Phlorizin is a bitter tasting compound. phlorizin is found, on average, in the highest concentration in a few different foods, such as mexican oregano, european plums, and apples and in a lower concentration in pomegranates and apricots. phlorizin has also been detected, but not quantified, in several different foods, such as epazotes, durians, chinese broccoli, sesames, and sweet potato. This could make phlorizin a potential biomarker for the consumption of these foods. It is of sweet taste and contains four molecules of water in the crystal. Phlorizin is found primarily in unripe Malus (apple), root bark of apple, trace amounts have been found in strawberry. It is poorly soluble in ether and cold water, but soluble in ethanol and hot water. Closely related species, such as pear (Pyrus communis), cherry, and other fruit trees in the Rosaceae do not contain phloridzin. Phlorizin was studied as a potential pharmaceutical treatment for type 2 diabetes, but has since been superseded by more selective and more promising synthetic analogs, such as empagliflozin, canagliflozin and dapagliflozin. Phlorizin is a competitive inhibitor of SGLT1 and SGLT2 because it competes with D-glucose for binding to the carrier; this reduces renal glucose transport, lowering the amount of glucose in the blood. Phlorizin is not an effective drug because when orally consumed, it is nearly entirely converted into phloretin by hydrolytic enzymes in the small intestine. Above 200 °C, it decomposes. Phlorizin is an aryl beta-D-glucoside that is phloretin attached to a beta-D-glucopyranosyl residue at position 2 via a glycosidic linkage. It has a role as a plant metabolite and an antioxidant.

Carnitine

C7H15NO3 (161.105188)

(R)-carnitine is the (R)-enantiomer of carnitine. It has a role as an antilipemic drug, a water-soluble vitamin (role), a nutraceutical, a nootropic agent and a Saccharomyces cerevisiae metabolite. It is a conjugate base of a (R)-carnitinium. It is an enantiomer of a (S)-carnitine. Constituent of striated muscle and liver. It is used therapeutically to stimulate gastric and pancreatic secretions and in the treatment of hyperlipoproteinemias. L-Carnitine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Levocarnitine is a Carnitine Analog. Levocarnitine is a natural product found in Mucidula mucida, Pseudo-nitzschia multistriata, and other organisms with data available. Levocarnitine is an amino acid derivative. Levocarnitine facilitates long-chain fatty acid entry into mitochondria, delivering substrate for oxidation and subsequent energy production. Fatty acids are utilized as an energy substrate in all tissues except the brain. (NCI04) Carnitine is not an essential amino acid; it can be synthesized in the body. However, it is so important in providing energy to muscles including the heart-that some researchers are now recommending carnitine supplements in the diet, particularly for people who do not consume much red meat, the main food source for carnitine. Carnitine has been described as a vitamin, an amino acid, or a metabimin, i.e., an essential metabolite. Like the B vitamins, carnitine contains nitrogen and is very soluble in water, and to some researchers carnitine is a vitamin (Liebovitz 1984). It was found that an animal (yellow mealworm) could not grow without carnitine in its diet. However, as it turned out, almost all other animals, including humans, do make their own carnitine; thus, it is no longer considered a vitamin. Nevertheless, in certain circumstances-such as deficiencies of methionine, lysine or vitamin C or kidney dialysis--carnitine shortages develop. Under these conditions, carnitine must be absorbed from food, and for this reason it is sometimes referred to as a metabimin or a conditionally essential metabolite. Like the other amino acids used or manufactured by the body, carnitine is an amine. But like choline, which is sometimes considered to be a B vitamin, carnitine is also an alcohol (specifically, a trimethylated carboxy-alcohol). Thus, carnitine is an unusual amino acid and has different functions than most other amino acids, which are most usually employed by the body in the construction of protein. Carnitine is an essential factor in fatty acid metabolism in mammals. Its most important known metabolic function is to transport fat into the mitochondria of muscle cells, including those in the heart, for oxidation. This is how the heart gets most of its energy. In humans, about 25\\\\\% of carnitine is synthesized in the liver, kidney and brain from the amino acids lysine and methionine. Most of the carnitine in the body comes from dietary sources such as red meat and dairy products. Inborn errors of carnitine metabolism can lead to brain deterioration like that of Reyes syndrome, gradually worsening muscle weakness, Duchenne-like muscular dystrophy and extreme muscle weakness with fat accumulation in muscles. Borurn et al. (1979) describe carnitine as an essential nutrient for pre-term babies, certain types (non-ketotic) of hypoglycemics, kidney dialysis patients, cirrhosis, and in kwashiorkor, type IV hyperlipidemia, heart muscle disease (cardiomyopathy), and propionic or organic aciduria (acid urine resulting from genetic or other anomalies). In all these conditions and the inborn errors of carnitine metabolism, carnitine is essential to life and carnitine supplements are valuable. carnitine therapy may also be useful in a wide variety of clinical conditions. carnitine supplementation has improved some patients who have angina secondary to coronary artery disease. It may be worth a trial in any form of hyperlipidemia or muscle weakness. carnitine supplements may... (-)-Carnitine. CAS Common Chemistry.

L-Valine

C5H11NO2 (117.0789746)

L-valine is the L-enantiomer of valine. It has a role as a nutraceutical, a micronutrient, a human metabolite, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a pyruvate family amino acid, a proteinogenic amino acid, a valine and a L-alpha-amino acid. It is a conjugate base of a L-valinium. It is a conjugate acid of a L-valinate. It is an enantiomer of a D-valine. It is a tautomer of a L-valine zwitterion. Valine is a branched-chain essential amino acid that has stimulant activity. It promotes muscle growth and tissue repair. It is a precursor in the penicillin biosynthetic pathway. L-Valine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Valine is an aliphatic and extremely hydrophobic essential amino acid in humans related to leucine, Valine is found in many proteins, mostly in the interior of globular proteins helping to determine three-dimensional structure. A glycogenic amino acid, valine maintains mental vigor, muscle coordination, and emotional calm. Valine is obtained from soy, cheese, fish, meats and vegetables. Valine supplements are used for muscle growth, tissue repair, and energy. (NCI04) Valine (abbreviated as Val or V) is an -amino acid with the chemical formula HO2CCH(NH2)CH(CH3)2. It is named after the plant valerian. L-Valine is one of 20 proteinogenic amino acids. Its codons are GUU, GUC, GUA, and GUG. This essential amino acid is classified as nonpolar. Along with leucine and isoleucine, valine is a branched-chain amino acid. Branched chain amino acids (BCAA) are essential amino acids whose carbon structure is marked by a branch point. These three amino acids are critical to human life and are particularly involved in stress, energy and muscle metabolism. BCAA supplementation as therapy, both oral and intravenous, in human health and disease holds great promise. BCAA denotes valine, isoleucine and leucine which are branched chain essential amino acids. Despite their structural similarities, the branched amino acids have different metabolic routes, with valine going solely to carbohydrates, leucine solely to fats and isoleucine to both. The different metabolism accounts for different requirements for these essential amino acids in humans: 12 mg/kg, 14 mg/kg and 16 mg/kg of valine, leucine and isoleucine respectively. Furthermore, these amino acids have different deficiency symptoms. Valine deficiency is marked by neurological defects in the brain, while isoleucine deficiency is marked by muscle tremors. Many types of inborn errors of BCAA metabolism exist, and are marked by various abnormalities. The most common form is the maple syrup urine disease, marked by a characteristic urinary odor. Other abnormalities are associated with a wide range of symptoms, such as mental retardation, ataxia, hypoglycemia, spinal muscle atrophy, rash, vomiting and excessive muscle movement. Most forms of BCAA metabolism errors are corrected by dietary restriction of BCAA and at least one form is correctable by supplementation with 10 mg of biotin daily. BCAA are decreased in patients with liver disease, such as hepatitis, hepatic coma, cirrhosis, extrahepatic biliary atresia or portacaval shunt; aromatic amino acids (AAA) tyrosine, tryptophan and phenylalanine, as well as methionine are increased in these conditions. Valine in particular, has been established as a useful supplemental therapy to the ailing liver. All the BCAA probably compete with AAA for absorption into the brain. Supplemental BCAA with vitamin B6 and zinc help normalize the BCAA:AAA ratio. In sickle-cell disease, valine substitutes for the hydrophilic amino acid glutamic acid in hemoglobin. Because valine is hydrophobic, the hemoglobin does not fold correctly. Valine is an essential amino acid, hence it must be ingested, usually as a component of proteins. A branched-chain essential amino acid that has stimulant activity. It promotes muscle growth and ... Valine (Val) or L-valine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (‚ÄìNH2) and carboxyl (‚ÄìCOOH) functional groups, along with a side chain (R group) specific to each amino acid. L-valine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Valine is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aliphatic amino acid. Valine was first isolated from casein in 1901 by Hermann Emil Fischer. The name valine comes from valeric acid, which in turn is named after the plant valerian due to the presence of valine in the roots of the plant. Valine is essential in humans, meaning the body cannot synthesize it, and it must be obtained from the diet. Human dietary sources are foods that contain protein, such as meats, dairy products, soy products, beans and legumes. L-valine is a branched chain amino acid (BCAA). The BCAAs consist of leucine, valine and isoleucine (and occasionally threonine). BCAAs are essential amino acids whose carbon structure is marked by a branch point at the beta-carbon position. BCAAs are critical to human life and are particularly involved in stress, energy and muscle metabolism. BCAA supplementation as therapy, both oral and intravenous, in human health and disease holds great promise. BCAAs have different metabolic routes, with valine going solely to carbohydrates (glucogenic), leucine solely to fats (ketogenic) and isoleucine being both a glucogenic and a ketogenic amino acid. The different metabolism accounts for different requirements for these essential amino acids in humans: 12 mg/kg, 14 mg/kg and 16 mg/kg of valine, leucine and isoleucine respectively. Like other branched-chain amino acids, the catabolism of valine starts with the removal of the amino group by transamination, giving alpha-ketoisovalerate, an alpha-keto acid, which is converted to isobutyryl-CoA through oxidative decarboxylation by the branched-chain Œ±-ketoacid dehydrogenase complex. This is further oxidised and rearranged to succinyl-CoA, which can enter the citric acid cycle. Furthermore, these amino acids have different deficiency symptoms. Valine deficiency is marked by neurological defects in the brain, while isoleucine deficiency is marked by muscle tremors. Many types of inborn errors of BCAA metabolism exist, and are marked by various abnormalities. The most common form is the maple syrup urine disease, marked by a characteristic urinary odor. Other abnormalities are associated with a wide range of symptoms, such as mental retardation, ataxia, hypoglycemia, spinal muscle atrophy, rash, vomiting and excessive muscle movement. Most forms of BCAA metabolism errors are corrected by dietary restriction of BCAA and at least one form is correctable by supplementation with 10 mg of biotin daily. BCAA are decreased in patients with liver disease, such as hepatitis, hepatic coma, cirrhosis, extrahepatic biliary atresia or portacaval shunt. Valine in particular, has been established as a useful supplemental therapy to the ailing liver. Valine, like other branched-chain amino acids, is associated with insulin resistance: higher levels of valine are observed in the blood of diabetic mice, rats, and humans (PMID: 25287287). Mice fed a valine deprivation diet for one day have improved insulin sensitivity and feeding of a valine deprivation diet for one week significantly decreases blood glucose levels (PMID: 24684822). In diet-induced obese and insulin resistant mice, a diet with decreased levels of valine and the other branched-chain amino acids results in reduced adiposity and improved insulin sensitivity (PMID: 29266268). In sickle-cell disease, valine substitutes for the hydrophilic amino acid glutamic acid in hemoglobin. Because valine ... L-valine, also known as (2s)-2-amino-3-methylbutanoic acid or L-(+)-alpha-aminoisovaleric acid, belongs to valine and derivatives class of compounds. Those are compounds containing valine or a derivative thereof resulting from reaction of valine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. L-valine is soluble (in water) and a moderately acidic compound (based on its pKa). L-valine can be found in watermelon, which makes L-valine a potential biomarker for the consumption of this food product. L-valine can be found primarily in most biofluids, including cerebrospinal fluid (CSF), breast milk, urine, and blood, as well as in human epidermis and fibroblasts tissues. L-valine exists in all living species, ranging from bacteria to humans. In humans, L-valine is involved in several metabolic pathways, some of which include streptomycin action pathway, tetracycline action pathway, methacycline action pathway, and kanamycin action pathway. L-valine is also involved in several metabolic disorders, some of which include methylmalonic aciduria due to cobalamin-related disorders, 3-methylglutaconic aciduria type III, isovaleric aciduria, and methylmalonic aciduria. Moreover, L-valine is found to be associated with schizophrenia, alzheimers disease, paraquat poisoning, and hypervalinemia. L-valine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Valine (abbreviated as Val or V) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH3+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain isopropyl group, making it a non-polar aliphatic amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet. Human dietary sources are foods that contain protein, such as meats, dairy products, soy products, beans and legumes. In the genetic code it is encoded by all codons starting with GU, namely GUU, GUC, GUA, and GUG (Applies to Valine, Leucine and Isoleucine)
This group of essential amino acids are identified as the branched-chain amino acids, BCAAs. Because this arrangement of carbon atoms cannot be made by humans, these amino acids are an essential element in the diet. The catabolism of all three compounds initiates in muscle and yields NADH and FADH2 which can be utilized for ATP generation. The catabolism of all three of these amino acids uses the same enzymes in the first two steps. The first step in each case is a transamination using a single BCAA aminotransferase, with a-ketoglutarate as amine acceptor. As a result, three different a-keto acids are produced and are oxidized using a common branched-chain a-keto acid dehydrogenase, yielding the three different CoA derivatives. Subsequently the metabolic pathways diverge, producing many intermediates.
The principal product from valine is propionylCoA, the glucogenic precursor of succinyl-CoA. Isoleucine catabolism terminates with production of acetylCoA and propionylCoA; thus isoleucine is both glucogenic and ketogenic. Leucine gives rise to acetylCoA and acetoacetylCoA, and is thus classified as strictly ketogenic.
There are a number of genetic diseases associated with faulty catabolism of the BCAAs. The most common defect is in the branched-chain a-keto acid dehydrogenase. Since there is only one dehydrogenase enzyme for all three amino acids, all three a-keto acids accumulate and are excreted in the urine. The disease is known as Maple syrup urine disease because of the characteristic odor of the urine in afflicted individuals. Mental retardation in these cases is extensive. Unfortunately, since these are essential amino acids, they cannot be heavily restricted in the diet; ultimately, the life of afflicted individuals is short and development is abnormal The main neurological pr...

Naringenin

C15H12O5 (272.0684702)

Naringenin is a flavorless, colorless flavanone, a type of flavonoid. It is the predominant flavanone in grapefruit, and is found in a variety of fruits and herbs. Naringenin has the skeleton structure of a flavanone with three hydroxy groups at the 4, 5, and 7 carbons. It may be found both in the aglycol form, naringenin, or in its glycosidic form, naringin, which has the addition of the disaccharide neohesperidose attached via a glycosidic linkage at carbon 7. Naringenin (not to be confused with naringin) is a flavanone that is considered to have a bioactive effect on human health as antioxidant, free radical scavenger, antiinflammatory, carbohydrate metabolism promoter, immunity system modulater. This substance has also been shown to repair DNA. Scientists exposed cells to 80 micomoles of naringenin per liter, for 24 hours, and found that the amount of hydroxyl damage to the DNA was reduced by 24 percent in that very short period of time. Unfortunately, this bioflavonoid is difficult to absorb on oral ingestion. Only 15\\\\\\\% of ingested naringenin will get absorbed, in the human gastrointestinal tract, in the best case scenario. A full glass of orange juice will supply about enough naringenin to achieve a concentration of about 0.5 micromoles per liter. Naringenin is a biomarker for the consumption of citrus fruits.

Deoxythymidine is also a parent compound for other transformation products, including but not limited to, tritiated thymidine, alpha-tritiated thymidine, and 5,6-dihydrothymidine. Deoxythymidine can be found in a number of food items such as butternut squash, mammee apple, catjang pea, and climbing bean, which makes deoxythymidine a potential biomarker for the consumption of these food products. Deoxythymidine can be found primarily in most biofluids, including blood, amniotic fluid, cerebrospinal fluid (CSF), and urine, as well as throughout most human tissues. Deoxythymidine exists in all living species, ranging from bacteria to humans. In humans, deoxythymidine is involved in the pyrimidine metabolism. Deoxythymidine is also involved in few metabolic disorders, which include beta ureidopropionase deficiency, dihydropyrimidinase deficiency, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and UMP synthase deficiency (orotic aciduria).

Deoxythymidine (or thymidine) is the DNA nucleoside T, which pairs with deoxyadenosine (A) in double-stranded DNA. Therefore, thymidine is essential to all life. Indeed, thymidine exists in all living species, ranging from bacteria to plants to humans. Within humans, thymidine participates in a number of enzymatic reactions. In particular, thymidine can be biosynthesized from 5-thymidylic acid through its interaction with the enzyme cytosolic purine 5-nucleotidase. In addition, thymidine can be converted into 5-thymidylic acid; which is catalyzed by the enzyme thymidine kinase. Deoxythymidine can be phosphorylated with one, two or three phosphoric acid groups, creating dTMP (deoxythymidine monophosphate), dTDP, or dTTP (for the di- and tri- phosphates, respectively). dTMP can be incorporated into DNA via DNA polymerases. In cell biology, thymidine can be used to synchronize the cells in S phase. Derivatives of thymidine are used in a number of drugs, including Azidothymidine (AZT), which is used in the treatment of HIV infection.

Vanillic acid

C8H8O4 (168.0422568)

Vanillic acid is a phenolic acid found in some forms of vanilla and many other plant extracts. It is a flavouring and scent agent that produces a pleasant, creamy odour. It is the intermediate product in the two-step bioconversion of ferulic acid to vanillin (J Biotechnol 1996;50(2-3):107-13).

Adenosine

C10H13N5O4 (267.09674980000005)

Adenosine is a ribonucleoside composed of a molecule of adenine attached to a ribofuranose moiety via a beta-N(9)-glycosidic bond. It has a role as an anti-arrhythmia drug, a vasodilator agent, an analgesic, a human metabolite and a fundamental metabolite. It is a purines D-ribonucleoside and a member of adenosines. It is functionally related to an adenine. The structure of adenosine was first described in 1931, though the vasodilating effects were not described in literature until the 1940s. Adenosine is indicated as an adjunct to thallium-201 in myocardial perfusion scintigraphy, though it is rarely used in this indication, having largely been replaced by [dipyridamole] and [regadenson]. Adenosine is also indicated in the treatment of supraventricular tachycardia. Adenosine was granted FDA approval on 30 October 1989. Adenosine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Adenosine is an Adenosine Receptor Agonist. The mechanism of action of adenosine is as an Adenosine Receptor Agonist. Adenosine is a natural product found in Smilax bracteata, Mikania laevigata, and other organisms with data available. Adenosine is a ribonucleoside comprised of adenine bound to ribose, with vasodilatory, antiarrhythmic and analgesic activities. Phosphorylated forms of adenosine play roles in cellular energy transfer, signal transduction and the synthesis of RNA. Adenosine is a nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. For instance, adenosine plays an important role in energy transfer - as adenosine triphosphate (ATP) and adenosine diphosphate (ADP). It also plays a role in signal transduction as cyclic adenosine monophosphate, cAMP. Adenosine itself is both a neurotransmitter and potent vasodilator. When administered intravenously, adenosine causes transient heart block in the AV node. Because of the effects of adenosine on AV node-dependent supraventricular tachycardia, adenosine is considered a class V antiarrhythmic agent. Adenosine is a metabolite found in or produced by Saccharomyces cerevisiae. A nucleoside that is composed of adenine and d-ribose.

When administered intravenously adenosine causes transient heart block in the AV node. Due to the effects of adenosine on AV node-dependent supraventricular tachycardia, adenosine is considered a class V antiarrhythmic agent. Overdoses of adenosine intake (as a drug) can lead to several side effects including chest pain, feeling faint, shortness of breath, and tingling of the senses. Serious side effects include a worsening dysrhythmia and low blood pressure. When present in sufficiently high levels, adenosine can act as an immunotoxin and a metabotoxin. An immunotoxin disrupts, limits the function, or destroys immune cells. A metabotoxin is an endogenous metabolite that causes adverse health effects at chronically high levels. Chronically high levels of adenosine are associated with adenosine deaminase deficiency. Adenosine is a precursor to deoxyadenosine, which is a precursor to dATP. A buildup of dATP in cells inhibits ribonucleotide reductase and prevents DNA synthesis, so cells are unable to divide. Since developing T cells and B cells are some of the most mitotically active cells, they are unable to divide and propagate to respond to immune challenges. High levels of deoxyadenosine also lead to an increase in S-adenosylhomocysteine, which is toxic to immature lymphocytes. Adenosine is a nucleoside composed of a molecule of adenine attached to a ribose sugar molecule (ribofuranose) moiety via a beta-N9-glycosidic bond. [Wikipedia].

Sucrose

C12H22O11 (342.1162062)

Sucrose is a nonreducing disaccharide composed of glucose and fructose linked via their anomeric carbons. It is obtained commercially from sugarcane (Saccharum officinarum), sugar beet (Beta vulgaris), and other plants and used extensively as a food and a sweetener. Sucrose is derived by crushing and extracting sugarcane with water or by extracting sugar beet with water, evaporating, and purifying with lime, carbon, and various liquids. Sucrose is also obtainable from sorghum. Sucrose occurs in low percentages in honey and maple syrup. Sucrose is used as a sweetener in foods and soft drinks, in the manufacture of syrups, in invert sugar, confectionery, preserves and jams, demulcent, pharmaceutical products, and caramel. Sucrose is also a chemical intermediate for detergents, emulsifying agents, and other sucrose derivatives. Sucrose is widespread in the seeds, leaves, fruits, flowers, and roots of plants, where it functions as an energy store for metabolism and as a carbon source for biosynthesis. The annual world production of sucrose is in excess of 90 million tons mainly from the juice of sugar cane (20\\\%) and sugar beet (17\\\%). In addition to its use as a sweetener, sucrose is used in food products as a preservative, antioxidant, moisture control agent, stabilizer, and thickening agent. BioTransformer predicts that sucrose is a product of 6-O-sinapoyl sucrose metabolism via a hydrolysis-of-carboxylic-acid-ester-pattern1 reaction occurring in human gut microbiota and catalyzed by the liver carboxylesterase 1 (P23141) enzyme (PMID: 30612223).

In chemistry, sugar loosely refers to a number of carbohydrates, such as monosaccharides, disaccharides, or oligosaccharides. In food, sugar refers to a class of edible crystalline carbohydrates, mainly sucrose, lactose, and fructose characterized by a sweet flavor. Other sugars are used in industrial food preparation, but are usually known by more specific names - glucose, fructose or fruit sugar, high fructose corn syrup, etc. Sugars is found in many foods, some of which are ucuhuba, butternut squash, common walnut, and miso. A glycosyl glycoside formed by glucose and fructose units joined by an acetal oxygen bridge from hemiacetal of glucose to the hemiketal of the fructose. Sucrose, a disaccharide, is a sugar composed of glucose and fructose subunits. It is produced naturally in plants and is the main constituent of white sugar. It has the molecular formula C 12H 22O 11. For human consumption, sucrose is extracted and refined from either sugarcane or sugar beet. Sugar mills – typically located in tropical regions near where sugarcane is grown – crush the cane and produce raw sugar which is shipped to other factories for refining into pure sucrose. Sugar beet factories are located in temperate climates where the beet is grown, and process the beets directly into refined sugar. The sugar-refining process involves washing the raw sugar crystals before dissolving them into a sugar syrup which is filtered and then passed over carbon to remove any residual colour. The sugar syrup is then concentrated by boiling under a vacuum and crystallized as the final purification process to produce crystals of pure sucrose that are clear, odorless, and sweet. Sugar is often an added ingredient in food production and recipes. About 185 million tonnes of sugar were produced worldwide in 2017.[6] Sucrose is particularly dangerous as a risk factor for tooth decay because Streptococcus mutans bacteria convert it into a sticky, extracellular, dextran-based polysaccharide that allows them to cohere, forming plaque. Sucrose is the only sugar that bacteria can use to form this sticky polysaccharide.[7] Sucrose. CAS Common Chemistry.

Capsaicin evokes numerous biological effects and thus has been the target of extensive., investigations since its initial identification in 1919. One of the most recognized physiological properties of capsaicin is its selective effects on the peripheral part of the sensory nervous system, particularly on the primary afferent neurons. The compound is known to deplete the neurotransmitter of painful impulses known as substance P from the sensory nerve terminals, which provides a rationale for its use as a versatile experimental tool for studying pain mechanisms and also for pharmacotherapy to treat some peripheral painful states, such as rheumatoid arthritis, post-herpetic neuralgia, post-mastectomy pain syndrome and diabetic neuropathy. Considering the frequent consumption of capsaicin as a food additive and its current therapeutic application, correct assessment of any harmful effects of this compound is important from the public health standpoint. Ingestion of large amounts of capsaicin has been reported to cause histopathological and biochemical changes, including erosion of gastric mucosa and hepatic necrosis. However, there are contradictory data on the mutagenicity of capsaicin. A recent epidemiological study conducted in Mexico revealed that consumers of chili pepper were at higher risk for gastric cancer than non-consumers. However, it remains unclear whether capsaicin present in hot chili pepper is a major causative factor in the aetiology of gastric cancer in humans. A growing number of recent studies have focused on anticarcinogenic or antimutagenic phytochemicals, particularly those included in human diet. In summary, capsaicin has dual effects on chemically induced carcinogenesis and mutagenesis.

5-Hydroxy-L-tryptophan

C11H12N2O3 (220.0847882)

5-Hydroxy-L-tryptophan is an aromatic amino acid naturally produced by the body from the essential amino acid L-tryptophan. 5-Hydroxy-L-tryptophan is the immediate precursor of the neurotransmitter serotonin. The conversion to serotonin is catalyzed by the enzyme aromatic L-amino acid decarboxylase (EC 4.1.1.28) (AADC1 also known as DOPA decarboxylase), an essential enzyme in the metabolism of the monoamine neurotransmitters. An accumulation of 5-hydroxy-L-tryptophan in cerebrospinal fluid occurs in aromatic L-amino acid decarboxylase deficiency (AADC deficiency) (OMIM: 608643) accompanied by an increased excretion in the urine of the patients, which are indicative of the disorder but not specific. 5-Hydroxy-L-tryptophan is also increased in other disorders such as in Parkinsons patients with severe postural instability and gait disorders. The amount of endogenous 5-hydroxy-L-tryptophan available for serotonin synthesis depends on the availability of tryptophan and on the activity of various enzymes, especially tryptophan hydroxylase (EC 1.14.16.4), indoleamine 2,3-dioxygenase (EC 1.13.11.52), and tryptophan 2,3-dioxygenase (TDO) (EC 1.13.11.11). 5-Hydroxy-L-tryptophan has been used clinically for over 30 years. In addition to its use in the treatment of depression, the therapeutic administration of 5-hydroxy-L-tryptophan has been shown to be effective in treating a wide variety of conditions, including fibromyalgia, insomnia, binge eating associated with obesity, cerebellar ataxia, and chronic headaches. 5-Hydroxy-L-tryptophan easily crosses the blood-brain barrier and effectively increases central nervous system (CNS) synthesis of serotonin. Supplementation with 5-hydroxy-L-tryptophan is hypothesized to normalize serotonin synthesis, which is putatively related to its antidepressant properties (PMID: 9295177, 17240182, 16023217). When present in sufficiently high levels, 5-hydroxytryptophan can be a neurotoxin and a metabotoxin. A neurotoxin is a compound that disrupts or attacks neural cells or tissue. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Signs and symptoms of AADC deficiency generally appear in the first year of life. Affected infants may have severe developmental delay, weak muscle tone (hypotonia), muscle stiffness, difficulty moving, and involuntary writhing movements of the limbs (athetosis). They may be lacking in energy (lethargic), feed poorly, startle easily, and have sleep disturbances. Since 5-hydroxytryptophan is a precursor to serotonin, altered levels of serotonin can accumulate in the brain, which leads to abnormal neural signalling. Infants with AADC deficiency have very low levels of neural signalling molecules while individuals who consume high levels of 5-hydroxytryptophan will have very high levels of neural signalling molecules. Both conditions can lead to vomiting, nausea, extreme drowsiness, and lethargy. 5-Hydroxytryptophan (5-HTP), also known as oxitriptan (INN) is sold over-the-counter in the United Kingdom, the United States, and Canada as a dietary supplement for use as an antidepressant, appetite suppressant, and sleep aid. It is also marketed in many European countries for the indication of major depression under trade names such as Cincofarm, Levothym, Levotonine, Oxyfan, Telesol, Tript-OH, and Triptum. Several double-blind placebo-controlled clinical trials have demonstrated the effectiveness of 5-HTP in the treatment of depression, though a lack of high-quality studies has been noted. More and larger studies are needed to determine if 5-HTP is truly effective in treating depression. 5-hydroxy-L-tryptophan is the L-enantiomer of 5-hydroxytryptophan. It has a role as a human metabolite, a plant metabolite and a mouse metabolite. It is a 5-hydroxytryptophan, a hydroxy-L-tryptophan and a non-proteinogenic L-alpha-amino acid. It is an enantiomer of a 5-hydroxy-D-tryptophan. It is a tautomer of a 5-hydroxy-L-tryptophan zwitterion. 5-Hydroxytryptophan (5-HTP), also known as oxitriptan (INN), is a naturally occurring amino acid and metabolic intermediate in the synthesis of serotonin and melatonin. 5-HTP is sold over-the-counter in the United Kingdom, United States and Canada as a dietary supplement for use as an antidepressant, appetite suppressant, and sleep aid, and is also marketed in many European countries for the indication of major depression under trade names like Cincofarm, Levothym, Levotonine, Oxyfan, Telesol, Tript-OH, and Triptum. Several double-blind placebo-controlled clinical trials have demonstrated the effectiveness of 5-HTP in the treatment of depression, though a lack of high quality studies has been noted. More study is needed to determine efficacy in treating depression. Oxitriptan is an aromatic amino acid with antidepressant activity. In vivo, oxitriptan (or 5-hydroxytryptophan) is converted into 5-hydroxytryptamine (5-HT or serotonin) as well as other neurotransmitters. Oxitriptan may exert its antidepressant activity via conversion to serotonin or directly by binding to serotonin (5-HT) receptors within the central nervous system (CNS). Endogenous oxitriptan is produced from the essential amino acid L-tryptophan. The exogenous therapeutic form is isolated from the seeds of the African plant Griffonia simplicifolia.

C5H5N5 (135.054493)

Adenine is the parent compound of the 6-aminopurines, composed of a purine having an amino group at C-6. It has a role as a human metabolite, a Daphnia magna metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a purine nucleobase and a member of 6-aminopurines. It derives from a hydride of a 9H-purine. A purine base and a fundamental unit of adenine nucleotides. Adenine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Adenine is a natural product found in Fritillaria cirrhosa, Annona purpurea, and other organisms with data available. Adenine is a purine nucleobase with an amine group attached to the carbon at position 6. Adenine is the precursor for adenosine and deoxyadenosine nucleosides. Adenine is a purine base. Adenine is found in both DNA and RNA. Adenine is a fundamental component of adenine nucleotides. Adenine forms adenosine, a nucleoside, when attached to ribose, and deoxyadenosine when attached to deoxyribose; it forms adenosine triphosphate (ATP), a nucleotide, when three phosphate groups are added to adenosine. Adenosine triphosphate is used in cellular metabolism as one of the basic methods of transferring chemical energy between chemical reactions. Purine inborn errors of metabolism (IEM) are serious hereditary disorders, which should be suspected in any case of neonatal fitting, failure to thrive, recurrent infections, neurological deficit, renal disease, self-mutilation and other manifestations.

Vitamin The parent compound of the 6-aminopurines, composed of a purine having an amino group at C-6. Adenine (/ˈædɪnɪn/) (symbol A or Ade) is a purine nucleobase. It is one of the four nucleobases in the nucleic acids of DNA, the other three being guanine (G), cytosine (C), and thymine (T). Adenine derivatives have various roles in biochemistry including cellular respiration, in the form of both the energy-rich adenosine triphosphate (ATP) and the cofactors nicotinamide adenine dinucleotide (NAD), flavin adenine dinucleotide (FAD) and Coenzyme A. It also has functions in protein synthesis and as a chemical component of DNA and RNA.[2] The shape of adenine is complementary to either thymine in DNA or uracil in RNA. The adjacent image shows pure adenine, as an independent molecule. When connected into DNA, a covalent bond is formed between deoxyribose sugar and the bottom left nitrogen (thereby removing the existing hydrogen atom). The remaining structure is called an adenine residue, as part of a larger molecule. Adenosine is adenine reacted with ribose, as used in RNA and ATP; Deoxyadenosine is adenine attached to deoxyribose, as used to form DNA. Adenine forms several tautomers, compounds that can be rapidly interconverted and are often considered equivalent. However, in isolated conditions, i.e. in an inert gas matrix and in the gas phase, mainly the 9H-adenine tautomer is found.[3][4] Purine metabolism involves the formation of adenine and guanine. Both adenine and guanine are derived from the nucleotide inosine monophosphate (IMP), which in turn is synthesized from a pre-existing ribose phosphate through a complex pathway using atoms from the amino acids glycine, glutamine, and aspartic acid, as well as the coenzyme tetrahydrofolate. Adenine (6-Aminopurine), a purine, is one of the four nucleobases in the nucleic acid of DNA. Adenine acts as a chemical component of DNA and RNA.

L-Tryptophan

C11H12N2O2 (204.0898732)

Tryptophan (Trp) or L-tryptophan is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-tryptophan is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Tryptophan is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aromatic amino acid. Tryptophan is an essential amino acid, meaning the body cannot synthesize it, and it must be obtained from the diet. The requirement for tryptophan and protein decreases with age. The minimum daily requirement for adults is 3 mg/kg/day or about 200 mg a day. There is 400 mg of tryptophan in a cup of wheat germ. A cup of low-fat cottage cheese contains 300 mg of tryptophan and chicken and turkey contain up to 600 mg of tryptophan per pound (http://www.dcnutrition.com). Tryptophan is particularly plentiful in chocolate, oats, dried dates, milk, yogurt, cottage cheese, red meat, eggs, fish, poultry, sesame, chickpeas, almonds, sunflower seeds, pumpkin seeds, buckwheat, spirulina, and peanuts. Tryptophan is the precursor of both serotonin and melatonin. Melatonin is a hormone that is produced by the pineal gland in animals, which regulates sleep and wakefulness. Serotonin is a brain neurotransmitter, platelet clotting factor, and neurohormone found in organs throughout the body. Metabolism of tryptophan into serotonin requires nutrients such as vitamin B6, niacin, and glutathione. Niacin (also known as vitamin B3) is an important metabolite of tryptophan. It is synthesized via kynurenine and quinolinic acids, which are products of tryptophan degradation. There are a number of conditions or diseases that are characterized by tryptophan deficiencies. For instance, fructose malabsorption causes improper absorption of tryptophan in the intestine, which reduces levels of tryptophan in the blood and leads to depression. High corn diets or other tryptophan-deficient diets can cause pellagra, which is a niacin-tryptophan deficiency disease with symptoms of dermatitis, diarrhea, and dementia. Hartnups disease is a disorder in which tryptophan and other amino acids are not absorbed properly. Symptoms of Hartnups disease include skin rashes, difficulty coordinating movements (cerebellar ataxia), and psychiatric symptoms such as depression or psychosis. Tryptophan supplements may be useful for treating Hartnups disease. Assessment of tryptophan deficiency is done through studying excretion of tryptophan metabolites in the urine or blood. Blood may be the most sensitive test because the amino acid tryptophan is transported in a unique way. Increased urination of tryptophan breakdown products (such as kynurenine) correlates with increased tryptophan degradation, which occurs with oral contraception, depression, mental retardation, hypertension, and anxiety states. Tryptophan plays a role in "feast-induced" drowsiness. Ingestion of a meal rich in carbohydrates triggers the release of insulin. Insulin, in turn, stimulates the uptake of large neutral branched-chain amino acids (BCAAs) into muscle, increasing the ratio of tryptophan to BCAA in the bloodstream. The increased tryptophan ratio reduces competition at the large neutral amino acid transporter (which transports both BCAAs and tryptophan), resulting in greater uptake of tryptophan across the blood-brain barrier into the cerebrospinal fluid (CSF). Once in the CSF, tryptophan is converted into serotonin and the resulting serotonin is further metabolized into melatonin by the pineal gland, which promotes sleep. Because tryptophan is converted into 5-hydroxytryptophan (5-HTP) which is then converted into the neurotransmitter serotonin, it has been proposed th... L-tryptophan is a white powder with a flat taste. An essential amino acid; occurs in isomeric forms. (NTP, 1992) L-tryptophan is the L-enantiomer of tryptophan. It has a role as an antidepressant, a nutraceutical, a micronutrient, a plant metabolite, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is an erythrose 4-phosphate/phosphoenolpyruvate family amino acid, a proteinogenic amino acid, a tryptophan and a L-alpha-amino acid. It is a conjugate base of a L-tryptophanium. It is a conjugate acid of a L-tryptophanate. It is an enantiomer of a D-tryptophan. It is a tautomer of a L-tryptophan zwitterion. An essential amino acid that is necessary for normal growth in infants and for nitrogen balance in adults. It is a precursor of indole alkaloids in plants. It is a precursor of serotonin (hence its use as an antidepressant and sleep aid). It can be a precursor to niacin, albeit inefficiently, in mammals. L-Tryptophan is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Tryptophan is the least plentiful of all 22 amino acids and an essential amino acid in humans (provided by food), Tryptophan is found in most proteins and a precursor of serotonin. Tryptophan is converted to 5-hydroxy-tryptophan (5-HTP), converted in turn to serotonin, a neurotransmitter essential in regulating appetite, sleep, mood, and pain. Tryptophan is a natural sedative and present in dairy products, meats, brown rice, fish, and soybeans. (NCI04) Tryptophan is an essential amino acid which is the precursor of serotonin. Serotonin is a brain neurotransmitter, platelet clotting factor and neurohormone found in organs throughout the body. Metabolism of tryptophan to serotonin requires nutrients such as vitamin B6, niacin and glutathione. Niacin is an important metabolite of tryptophan. High corn or other tryptophan-deficient diets can cause pellagra, which is a niacin-tryptophan deficiency disease with symptoms of dermatitis, diarrhea and dementia. Inborn errors of tryptophan metabolism exist where a tumor (carcinoid) makes excess serotonin. Hartnups disease is a disease where tryptophan and other amino acids are not absorbed properly. Tryptophan supplements may be useful in each condition, in carcinoid replacing the over-metabolized nutrient and in Hartnups supplementing a malabsorbed nutrient. Some disorders of excess tryptophan in the blood may contribute to mental retardation. Assessment of tryptophan deficiency is done through studying excretion of tryptophan metabolites in the urine or blood. Blood may be the most sensitive test because the amino acid tryptophan is transported in a unique way. Increased urination of tryptophan fragments correlates with increased tryptophan degradation, which occurs with oral contraception, depression, mental retardation, hypertension and anxiety states. The requirement for tryptophan and protein decreases with age. Adults minimum daily requirement is 3 mg/kg/day or about 200 mg a day.

Azelaic acid (AZA) is a naturally occurring saturated nine-carbon dicarboxylic acid (COOH (CH2)7-COOH). It possesses a variety of biological actions both in vitro and in vivo. Interest in the biological activity of AZA arose originally out of studies of skin surface lipids and the pathogenesis of hypochromia in pityriasis versicolor infection. Later, it was shown that Pityrosporum can oxidize unsaturated fatty acids to C8-C12 dicarboxylic acids that are cornpetitive inhibitors of tyrosinase in vitro. Azelaic acid was chosen for further investigation and development of a new topical drug for treating hyperpigmentary disorders for the following reasons: it possesses a middle-range of antityrosinase activity, is inexpensive, and more soluble to be incorporated into a base cream than other dicarboxylic acids. Azelaic acid is another option for the topical treatment of mild to moderate inflammatory acne vulgaris. It offers effectiveness similar to that of other agents without the systemic side effects of oral antibiotics or the allergic sensitization of topical benzoyl peroxide and with less irritation than tretinoin. Azelaic acid is less expensive than certain other prescription acne preparations, but it is much more expensive than nonprescription benzoyl peroxide preparations. Whether it is safe and effective when used in combination with other agents is not known. (PMID: 7737781, 8961845). An alpha,omega-dicarboxylic acid that is heptane substituted at positions 1 and 7 by carboxy groups. Plants biology In plants, azelaic acid serves as a "distress flare" involved in defense responses after infection.[7] It serves as a signal that induces the accumulation of salicylic acid, an important component of a plant's defensive response.[8] Human biology The mechanism of action in humans is thought to be through the inhibition of hyperactive protease activity that converts cathelicidin into the antimicrobial skin peptide LL-37.[9] Polymers and related materials Esters of this dicarboxylic acid find applications in lubrication and plasticizers. In lubricant industries it is used as a thickening agent in lithium complex grease. With hexamethylenediamine, azelaic acid forms Nylon-6,9, which finds specialized uses as a plastic.[4] Medical Azelaic acid is used to treat mild to moderate acne, both comedonal acne and inflammatory acne.[10][11] It belongs to a class of medication called dicarboxylic acids. It works by killing acne bacteria that infect skin pores. It also decreases the production of keratin, which is a natural substance that promotes the growth[clarification needed] of acne bacteria.[12] Azelaic acid is also used as a topical gel treatment for rosacea, due to its ability to reduce inflammation.[11] It clears the bumps and swelling caused by rosacea. In topical pharmaceutical preparations and scientific research AzA is typically used in concentrations between 15\\\% and 20\\\% but some research demonstrates that in certain vehicle formulations the pharmaceutical effects of 10\\\% Azelaic acid has the potential to be fully comparable to that of some 20\\\% creams.[13] Acne treatment Azelaic acid is effective for mild to moderate acne when applied topically at a 15\\\%-20\\\% concentration.[14][15][16][17] In patients with moderate acne, twice daily application over 3 months of 20\\\% AzA significantly reduced the number of comedones, papules, and pustules;[18][19] at this strength, it’s considered to be as effective as benzoyl peroxide 5\\\%, tretinoin 0.05\\\%, erythromycin 2\\\%, and oral tetracycline at 500 mg-1000 mg.[20][21] In a comparative review of effects of topical AzA, Salicylic acid, Nicotinamide, Sulfur, Zinc, and alpha-hydroxy acid, AzA had more high-quality evidence of effectiveness than the rest.[22] Results can be expected after 4 weeks of twice-daily treatment. The effectiveness of long term use is unclear, but it’s been recommended that AzA be used for at least 6 months continuously for maintenance.[20] Whitening agent Azelaic acid is used for treatment of skin pigmentation, including melasma and postinflammatory hyperpigmentation, particularly in those with darker skin types. It has been recommended as an alternative to hydroquinone.[23] As a tyrosinase inhibitor,[5] azelaic acid reduces synthesis of melanin.[24] According to one report in 1988, azelaic acid in combination with zinc sulfate in vitro was found to be a potent (90\\\% inhibition) 5α-reductase inhibitor, similar to the hair loss drugs finasteride and dutasteride.[25] In vitro research during mid-1980s evaluating azelaic acid's depigmenting (whitening) capability concluded it is effective (cytotoxic to melanocytes) at only high concentrations.[26] A 1996 review claimed 20\\\% AzA is as potent as 4\\\% hydroquinone after a period of application of three months without the latter's adverse effects and even more effective if applied along with tretinoin for the same period of time.[27][19] Azelaic acid is a nine-carbon dicarboxylic acid. Azelaic acid has antimicrobial activity against Propionibacterium acnes and Staphylococcus epidermidis through inhibition of microbial cellular prorein synthesis. Azelaic acid has hypopigmentation action resulting from its ability to scavenge free radicals[1][2]. Azelaic acid is a nine-carbon dicarboxylic acid.

L-Tyrosine

C9H11NO3 (181.0738896)

Tyrosine (Tyr) or L-tyrosine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-tyrosine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Tyrosine is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aromatic amino acid. Tyrosine is a non-essential amino acid, meaning the body can synthesize it – usually from phenylalanine. The conversion of phenylalanine to tyrosine is catalyzed by the enzyme phenylalanine hydroxylase, a monooxygenase. This enzyme catalyzes the reaction causing the addition of a hydroxyl group to the end of the 6-carbon aromatic ring of phenylalanine, such that it becomes tyrosine. Tyrosine is found in many high-protein food products such as chicken, turkey, fish, milk, yogurt, cottage cheese, cheese, peanuts, almonds, pumpkin seeds, sesame seeds, soy products, lima beans, avocados and bananas. Tyrosine is one of the few amino acids that readily passes the blood-brain barrier. Once in the brain, it is a precursor for the neurotransmitters dopamine, norepinephrine and epinephrine, better known as adrenalin. These neurotransmitters are an important part of the bodys sympathetic nervous system, and their concentrations in the body and brain are directly dependent upon dietary tyrosine. Tyrosine is not found in large concentrations throughout the body, probably because it is rapidly metabolized. Folic acid, copper and vitamin C are cofactor nutrients of these reactions. Tyrosine is also the precursor for hormones, including thyroid hormones (diiodotyrosine), catecholestrogens and the major human pigment, melanin. Tyrosine is an important amino acid in many proteins, peptides and even enkephalins, the bodys natural pain reliever. Valine and other branched amino acids, and possibly tryptophan and phenylalanine may reduce tyrosine absorption. A number of genetic errors of tyrosine metabolism have been identified, such as hawkinsinuria and tyrosinemia I. The most common feature of these diseases is the increased amount of tyrosine in the blood, which is marked by decreased motor activity, lethargy and poor feeding. Infection and intellectual deficits may occur. Vitamin C supplements can help reverse these disease symptoms. Some adults also develop elevated tyrosine in their blood. This typically indicates a need for more vitamin C. More tyrosine is needed under stress, and tyrosine supplements prevent the stress-induced depletion of norepinephrine and can help aleviate biochemical depression. However, tyrosine may not be good for treating psychosis. Many antipsychotic medications apparently function by inhibiting tyrosine metabolism. L-Dopa, which is directly used in Parkinsons, is made from tyrosine. Tyrosine, the nutrient, can be used as an adjunct in the treatment of Parkinsons. Peripheral metabolism of tyrosine necessitates large doses of tyrosine, however, compared to L-Dopa (http://www.dcnutrition.com). In addition to its role as a precursor for neurotransmitters, tyrosine plays an important role for the function of many proteins. Within many proteins or enzymes, certain tyrosine residues can be tagged (at the hydroxyl group) with a phosphate group (phosphorylated) by specialized protein kinases. In its phosphorylated form, tyrosine is called phosphotyrosine. Tyrosine phosphorylation is considered to be one of the key steps in signal transduction and regulation of enzymatic activity. Tyrosine (or its precursor phenylalanine) is also needed to synthesize the benzoquinone structure which forms part of coenzyme Q10. L-tyrosine is an optically active form of tyrosine having L-configuration. It has a role as an EC 1.3.1.43 (arogenate dehydrogenase) inhibitor, a nutraceutical, a micronutrient and a fundamental metabolite. It is an erythrose 4-phosphate/phosphoenolpyruvate family amino acid, a proteinogenic amino acid, a tyrosine and a L-alpha-amino acid. It is functionally related to a L-tyrosinal. It is a conjugate base of a L-tyrosinium. It is a conjugate acid of a L-tyrosinate(1-). It is an enantiomer of a D-tyrosine. It is a tautomer of a L-tyrosine zwitterion. Tyrosine is a non-essential amino acid. In animals it is synthesized from [phenylalanine]. It is also the precursor of [epinephrine], thyroid hormones, and melanin. L-Tyrosine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). L-Tyrosine is the levorotatory isomer of the aromatic amino acid tyrosine. L-tyrosine is a naturally occurring tyrosine and is synthesized in vivo from L-phenylalanine. It is considered a non-essential amino acid; however, in patients with phenylketonuria who lack phenylalanine hydroxylase and cannot convert phenylalanine into tyrosine, it is considered an essential nutrient. In vivo, tyrosine plays a role in protein synthesis and serves as a precursor for the synthesis of catecholamines, thyroxine, and melanin. Tyrosine is an essential amino acid that readily passes the blood-brain barrier. Once in the brain, it is a precursor for the neurotransmitters dopamine, norepinephrine and epinephrine, better known as adrenalin.

linolenate(18:3)

C18H30O2 (278.224568)

alpha-Linolenic acid (ALA) is a polyunsaturated fatty acid (PUFA). It is a member of the group of essential fatty acids called omega-3 fatty acids. alpha-Linolenic acid, in particular, is not synthesized by mammals and therefore is an essential dietary requirement for all mammals. Certain nuts (English walnuts) and vegetable oils (canola, soybean, flaxseed/linseed, olive) are particularly rich in alpha-linolenic acid. Omega-3 fatty acids get their name based on the location of one of their first double bond. In all omega-3 fatty acids, the first double bond is located between the third and fourth carbon atom counting from the methyl end of the fatty acid (n-3). Although humans and other mammals can synthesize saturated and some monounsaturated fatty acids from carbon groups in carbohydrates and proteins, they lack the enzymes necessary to insert a cis double bond at the n-6 or the n-3 position of a fatty acid. Omega-3 fatty acids like alpha-linolenic acid are important structural components of cell membranes. When incorporated into phospholipids, they affect cell membrane properties such as fluidity, flexibility, permeability, and the activity of membrane-bound enzymes. Omega-3 fatty acids can modulate the expression of a number of genes, including those involved with fatty acid metabolism and inflammation. alpha-Linolenic acid and other omega-3 fatty acids may regulate gene expression by interacting with specific transcription factors, including peroxisome proliferator-activated receptors (PPARs) and liver X receptors (LXRs). alpha-Linolenic acid is found to be associated with isovaleric acidemia, which is an inborn error of metabolism. α-Linolenic acid can be obtained by humans only through their diets. Humans lack the desaturase enzymes required for processing stearic acid into A-linoleic acid or other unsaturated fatty acids. Dietary α-linolenic acid is metabolized to stearidonic acid, a precursor to a collection of polyunsaturated 20-, 22-, 24-, etc fatty acids (eicosatetraenoic acid, eicosapentaenoic acid, docosapentaenoic acid, tetracosapentaenoic acid, 6,9,12,15,18,21-tetracosahexaenoic acid, docosahexaenoic acid).[12] Because the efficacy of n−3 long-chain polyunsaturated fatty acid (LC-PUFA) synthesis decreases down the cascade of α-linolenic acid conversion, DHA synthesis from α-linolenic acid is even more restricted than that of EPA.[13] Conversion of ALA to DHA is higher in women than in men.[14] α-Linolenic acid, also known as alpha-linolenic acid (ALA) (from Greek alpha meaning "first" and linon meaning flax), is an n−3, or omega-3, essential fatty acid. ALA is found in many seeds and oils, including flaxseed, walnuts, chia, hemp, and many common vegetable oils. In terms of its structure, it is named all-cis-9,12,15-octadecatrienoic acid.[2] In physiological literature, it is listed by its lipid number, 18:3 (n−3). It is a carboxylic acid with an 18-carbon chain and three cis double bonds. The first double bond is located at the third carbon from the methyl end of the fatty acid chain, known as the n end. Thus, α-linolenic acid is a polyunsaturated n−3 (omega-3) fatty acid. It is a regioisomer of gamma-linolenic acid (GLA), an 18:3 (n−6) fatty acid (i.e., a polyunsaturated omega-6 fatty acid with three double bonds). Alpha-linolenic acid is a linolenic acid with cis-double bonds at positions 9, 12 and 15. Shown to have an antithrombotic effect. It has a role as a micronutrient, a nutraceutical and a mouse metabolite. It is an omega-3 fatty acid and a linolenic acid. It is a conjugate acid of an alpha-linolenate and a (9Z,12Z,15Z)-octadeca-9,12,15-trienoate. Alpha-linolenic acid (ALA) is a polyunsaturated omega-3 fatty acid. It is a component of many common vegetable oils and is important to human nutrition. alpha-Linolenic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Linolenic Acid is a natural product found in Prunus mume, Dipteryx lacunifera, and other organisms with data available. Linolenic Acid is an essential fatty acid belonging to the omega-3 fatty acids group. It is highly concentrated in certain plant oils and has been reported to inhibit the synthesis of prostaglandin resulting in reduced inflammation and prevention of certain chronic diseases. Alpha-linolenic acid (ALA) is a polyunsaturated omega-3 fatty acid. It is a component of many common vegetable oils and is important to human nutrition. A fatty acid that is found in plants and involved in the formation of prostaglandins. Seed oils are the richest sources of α-linolenic acid, notably those of hempseed, chia, perilla, flaxseed (linseed oil), rapeseed (canola), and soybeans. α-Linolenic acid is also obtained from the thylakoid membranes in the leaves of Pisum sativum (pea leaves).[3] Plant chloroplasts consisting of more than 95 percent of photosynthetic thylakoid membranes are highly fluid due to the large abundance of ALA, evident as sharp resonances in high-resolution carbon-13 NMR spectra.[4] Some studies state that ALA remains stable during processing and cooking.[5] However, other studies state that ALA might not be suitable for baking as it will polymerize with itself, a feature exploited in paint with transition metal catalysts. Some ALA may also oxidize at baking temperatures. Gamma-linolenic acid (γ-Linolenic acid) is an omega-6 (n-6), 18 carbon (18C-) polyunsaturated fatty acid (PUFA) extracted from Perilla frutescens. Gamma-linolenic acid supplements could restore needed PUFAs and mitigate the disease[1].

L-Threonine

C4H9NO3 (119.0582404)

L-threonine is an optically active form of threonine having L-configuration. It has a role as a nutraceutical, a micronutrient, a Saccharomyces cerevisiae metabolite, a plant metabolite, an Escherichia coli metabolite, a human metabolite, an algal metabolite and a mouse metabolite. It is an aspartate family amino acid, a proteinogenic amino acid, a threonine and a L-alpha-amino acid. It is a conjugate base of a L-threoninium. It is a conjugate acid of a L-threoninate. It is an enantiomer of a D-threonine. It is a tautomer of a L-threonine zwitterion. An essential amino acid occurring naturally in the L-form, which is the active form. It is found in eggs, milk, gelatin, and other proteins. L-Threonine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Threonine is an essential amino acid in humans (provided by food), Threonine is an important residue of many proteins, such as tooth enamel, collagen, and elastin. An important amino acid for the nervous system, threonine also plays an important role in porphyrin and fat metabolism and prevents fat buildup in the liver. Useful with intestinal disorders and indigestion, threonine has also been used to alleviate anxiety and mild depression. (NCI04) Threonine is an essential amino acid in humans. It is abundant in human plasma, particularly in newborns. Severe deficiency of threonine causes neurological dysfunction and lameness in experimental animals. Threonine is an immunostimulant which promotes the growth of thymus gland. It also can probably promote cell immune defense function. This amino acid has been useful in the treatment of genetic spasticity disorders and multiple sclerosis at a dose of 1 gram daily. It is highly concentrated in meat products, cottage cheese and wheat germ. The threonine content of most of the infant formulas currently on the market is approximately 20\\\\\\% higher than the threonine concentration in human milk. Due to this high threonine content the plasma threonine concentrations are up to twice as high in premature infants fed these formulas than in infants fed human milk. The whey proteins which are used for infant formulas are sweet whey proteins. Sweet whey results from cheese production. Threonine catabolism in mammals appears to be due primarily (70-80\\\\\\%) to the activity of threonine dehydrogenase (EC 1.1.1.103) that oxidizes threonine to 2-amino-3-oxobutyrate, which forms glycine and acetyl CoA, whereas threonine dehydratase (EC 4.2.1.16) that catabolizes threonine into 2-oxobutyrate and ammonia, is significantly less active. Increasing the threonine plasma concentrations leads to accumulation of threonine and glycine in the brain. Such accumulation affects the neurotransmitter balance which may have consequences for the brain development during early postnatal life. Thus, excessive threonine intake during infant feeding should be avoided. (A3450). An essential amino acid occurring naturally in the L-form, which is the active form. It is found in eggs, milk, gelatin, and other proteins. See also: Amlisimod (monomer of) ... View More ... Threonine (Thr) or L-threonine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-threonine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Threonine is found in all organisms ranging from bacteria to plants to animals. It is classified as a polar, uncharged (at physiological pH), aliphatic amino acid. Threonine is sometimes considered as a branched chain amino acid. Threonine was actually the last of the 20 amino acids to be discovered (in 1938). It was named threonine because it was similar in structure to threonic acid, a four-carbon monosaccharide. Threonine is an essential amino acid in humans, meaning the body cannot synthesize it and that it must be obtained from the diet. Foods high in threonine include cottage cheese, poultry, fish, meat, lentils, black turtle bean and sesame seeds. Adult humans require about 20 mg/kg body weight/day. In plants and microorganisms, threonine is synthesized from aspartic acid via alpha-aspartyl-semialdehyde and homoserine. In proteins, the threonine residue is susceptible to numerous posttranslational modifications. The hydroxyl side-chain can undergo O-linked glycosylation and phosphorylation through the action of a threonine kinase. Threonine is abundant in human plasma, particularly in newborns. Severe deficiency of threonine causes neurological dysfunction and lameness in experimental animals. Threonine is an immunostimulant which promotes the growth of thymus gland.

Nicotine

C10H14N2 (162.1156924)

Nicotine is an alkaloid found in the nightshade family of plants (Solanaceae), predominantly in tobacco and in lower quantities in tomato, potato, eggplant (aubergine), and green pepper. Nicotine alkaloids are also found in the leaves of the coca plant. Nicotine constitutes 0.3 to 5\\\% of the tobacco plant by dry weight, with biosynthesis taking place in the root and accumulation in the leaves. It is a potent neurotoxin with particular specificity to insects; therefore nicotine was widely used as an insecticide in the past and nicotine derivatives such as imidacloprid continue to be widely used. It has been noted that the majority of people diagnosed with schizophrenia smoke tobacco. Estimates for the number of schizophrenics that smoke range from 75\\\% to 90\\\%. It was recently argued that the increased level of smoking in schizophrenia may be due to a desire to self-medicate with nicotine. More recent research has found the reverse: it is a risk factor without long-term benefit, used only for its short-term effects. However, research on nicotine as administered through a patch or gum is ongoing. As nicotine enters the body, it is distributed quickly through the bloodstream and can cross the blood-brain barrier. On average, it takes about seven seconds for the substance to reach the brain. The half-life of nicotine in the body is around 2 hours. The amount of nicotine inhaled with tobacco smoke is a fraction of the amount contained in the tobacco leaves (most of the substance is destroyed by the heat). The amount of nicotine absorbed by the body from smoking depends on many factors, including the type of tobacco, whether the smoke is inhaled, and whether a filter is used. For chewing tobacco, often called dip, snuff, or sinus, which is held in the mouth between the lip and gum, the amount released into the body tends to be much greater than smoked tobacco. The currently available literature indicates that nicotine, on its own, does not promote the development of cancer in healthy tissue and has no mutagenic properties. Its teratogenic properties have not yet been adequately researched, and while the likelihood of birth defects caused by nicotine is believed to be very small or nonexistent, nicotine replacement product manufacturers recommend consultation with a physician before using a nicotine patch or nicotine gum while pregnant or nursing. However, nicotine and the increased acetylcholinic activity it causes have been shown to impede apoptosis, which is one of the methods by which the body destroys unwanted cells (programmed cell death). Since apoptosis helps to remove mutated or damaged cells that may eventually become cancerous, the inhibitory actions of nicotine create a more favourable environment for cancer to develop. Thus, nicotine plays an indirect role in carcinogenesis. It is also important to note that its addictive properties are often the primary motivating factor for tobacco smoking, contributing to the proliferation of cancer. Nicotine is a highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke. Nicotine is a hygroscopic, oily liquid that is miscible with water in its base form. As a nitrogenous base, nicotine forms salts with acids that are usually solid and water soluble. Nicotine easily penetrates the skin. As shown by the physical data, free base nicotine will burn at a temperature below its boiling point, and its vapours will combust at 95 °C in the air despite a low vapour pressure. Because of this, most nicotine is burned when a cigarette is smoked; however, enough is inhaled to provide the desired effects. Nicotine is a stimulant drug that acts as an agonist at nicotinic acetylcholine receptors. These are ionotropic receptors composed of five homomeric or heteromeric subunits. In the brain, nicotine binds to nic... Nicotine appears as a colorless to light yellow or brown liquid. Combustible. Toxic by inhalation and by skin absorption.

It is a conjugate base of a (S)-nicotinium(1+). It is an enantiomer of a (R)-nicotine. Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke. Nicotine is a Cholinergic Nicotinic Agonist. Nicotine is a natural alkyloid that is a major component of cigarettes and is used therapeutically to help with smoking cessation. Nicotine has not been associated with liver test abnormalities or with clinically apparent hepatotoxicity. Nicotine is a natural product found in Cyphanthera tasmanica, Nicotiana cavicola, and other organisms with data available. Nicotine is a plant alkaloid, found in the tobacco plant, and addictive central nervous system (CNS) stimulant that causes either ganglionic stimulation in low doses or ganglionic blockage in high doses. Nicotine acts as an agonist at the nicotinic cholinergic receptors in the autonomic ganglia, at neuromuscular junctions, and in the adrenal medulla and the brain. Nicotines CNS-stimulating activities may be mediated through the release of several neurotransmitters, including acetylcholine, beta-endorphin, dopamine, norepinephrine, serotonin, and ACTH. As a result, peripheral vasoconstriction, tachycardia, and elevated blood pressure may be observed with nicotine intake. This agent may also stimulate the chemoreceptor trigger zone, thereby inducing nausea and vomiting. Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission.

It is a vitamin B3, a pyridinecarboxamide and a pyridine alkaloid. It is functionally related to a nicotinic acid. An important compound functioning as a component of the coenzyme NAD. Its primary significance is in the prevention and/or cure of blacktongue and pellagra. Most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake. Niacinamide is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Nicotinamide is a natural product found in Mus musculus, Euonymus grandiflorus, and other organisms with data available. Niacinamide is the active form of vitamin B3 and a component of the coenzyme nicotinamide adenine dinucleotide (NAD). Niacinamide acts as a chemo- and radio-sensitizing agent by enhancing tumor blood flow, thereby reducing tumor hypoxia. This agent also inhibits poly(ADP-ribose) polymerases, enzymes involved in the rejoining of DNA strand breaks induced by radiation or chemotherapy. Nicotinamide is a uremic toxin. Uremic toxins can be subdivided into three major groups based upon their chemical and physical characteristics: 1) small, water-soluble, non-protein-bound compounds, such as urea; 2) small, lipid-soluble and/or protein-bound compounds, such as the phenols and 3) larger so-called middle-molecules, such as beta2-microglobulin. Chronic exposure of uremic toxins can lead to a number of conditions including renal damage, chronic kidney disease and cardiovascular disease. Niacinamide or vitamin B3 is an important compound functioning as a component of the coenzyme NAD. Its primary significance is in the prevention and/or cure of blacktongue and pellagra. Most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake. Niacinamide is used to increase the effect of radiation therapy on tumor cells. Niacin (nicotinic acid) and niacinamide, while both labeled as vitamin B3 also have different applications. Niacinamide is useful in arthritis and early-onset type I diabetes while niacin is an effective reducer of high cholesterol levels. Niacinamide is a metabolite found in or produced by Saccharomyces cerevisiae. An important compound functioning as a component of the coenzyme NAD. Its primary significance is in the prevention and/or cure of blacktongue and PELLAGRA. Most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake.

Niacinamide, also known as nicotinamide (NAM), is a form of vitamin B3 found in food and used as a dietary supplement and medication. Niacinamide belongs to the class of organic compounds known as nicotinamides. These are heterocyclic aromatic compounds containing a pyridine ring substituted at position 3 by a carboxamide group. Its primary significance is in the prevention and/or cure of blacktongue and pellagra. The structure of nicotinamide consists of a pyridine ring to which a primary amide group is attached in the meta position. It is an amide of nicotinic acid. As an aromatic compound, it undergoes electrophilic substitution reactions and transformations of its two functional groups. Niacinamide and phosphoribosyl pyrophosphate can be converted into nicotinic acid mononucleotide and phosphate by the enzyme nicotinamide phosphoribosyltransferase. In humans, niacinamide is involved in the metabolic disorder called the nad+ signalling pathway (cancer). Niacinamide is an odorless tasting compound. Outside of the human body, niacinamide is found, on average, in the highest concentration within a few different foods, such as common sages, cow milk, and cocoa beans and in a lower concentration in common pea. Niacinamide has also been detected, but not quantified in several different foods, such as yardlong beans, roselles, apples, oyster mushrooms, and swiss chards. Niacinamide occurs in trace amounts mainly in meat, fish, nuts, and mushrooms, as well as to a lesser extent in some vegetables. It is commonly added to cereals and other foods. Many multivitamins contain 20–30 mg of vitamin B3 and it is also available in higher doses. Most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake.

Nicotinic acid

C6H5NO2 (123.032027)

Nicotinic acid is an odorless white crystalline powder with a feebly acid taste. pH (saturated aqueous solution) 2.7. pH (1.3\\\\\% solution) 3-3.5. (NTP, 1992) Nicotinic acid is a pyridinemonocarboxylic acid that is pyridine in which the hydrogen at position 3 is replaced by a carboxy group. It has a role as an antidote, an antilipemic drug, a vasodilator agent, a metabolite, an EC 3.5.1.19 (nicotinamidase) inhibitor, an Escherichia coli metabolite, a mouse metabolite, a human urinary metabolite and a plant metabolite. It is a vitamin B3, a pyridinemonocarboxylic acid and a pyridine alkaloid. It is a conjugate acid of a nicotinate. Niacin is a B vitamin used to treat vitamin deficiencies as well as hyperlipidemia, dyslipidemia, hypertriglyceridemia, and to reduce the risk of myocardial infarctions. Nicotinic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Niacin is a Nicotinic Acid. Niacin, also known as nicotinic acid and vitamin B3, is a water soluble, essential B vitamin that, when given in high doses, is effective in lowering low density lipoprotein (LDL) cholesterol and raising high density lipoprotein (HDL) cholesterol, which makes this agent of unique value in the therapy of dyslipidemia. Niacin can cause mild-to-moderate serum aminotransferase elevations and high doses and certain formulations of niacin have been linked to clinically apparent, acute liver injury which can be severe as well as fatal. Niacin is a water-soluble vitamin belonging to the vitamin B family, which occurs in many animal and plant tissues, with antihyperlipidemic activity. Niacin is converted to its active form niacinamide, which is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and its phosphate form, NADP. These coenzymes play an important role in tissue respiration and in glycogen, lipid, amino acid, protein, and purine metabolism. Although the exact mechanism of action by which niacin lowers cholesterol is not fully understood, it may act by inhibiting the synthesis of very low density lipoproteins (VLDL), inhibiting the release of free fatty acids from adipose tissue, increasing lipoprotein lipase activity, and reducing the hepatic synthesis of VLDL-C and LDL-C. Nicotinic acid, also known as niacin or vitamin B3, is a water-soluble vitamin whose derivatives such as NADH, NAD, NAD+, and NADP play essential roles in energy metabolism in the living cell and DNA repair. The designation vitamin B3 also includes the amide form, nicotinamide or niacinamide. Severe lack of niacin causes the deficiency disease pellagra, whereas a mild deficiency slows down the metabolism decreasing cold tolerance. The recommended daily allowance of niacin is 2-12 mg a day for children, 14 mg a day for women, 16 mg a day for men, and 18 mg a day for pregnant or breast-feeding women. It is found in various animal and plant tissues and has pellagra-curative, vasodilating, and antilipemic properties. The liver can synthesize niacin from the essential amino acid tryptophan (see below), but the synthesis is extremely slow and requires vitamin B6; 60 mg of tryptophan are required to make one milligram of niacin. Bacteria in the gut may also perform the conversion but are inefficient. A water-soluble vitamin of the B complex occurring in various animal and plant tissues.

Vitamin D3

C27H44O (384.3391974)

Vitamin d3 appears as fine colorless crystals. Water insoluble. (NTP, 1992) Calciol is a hydroxy seco-steroid that is (5Z,7E)-9,10-secocholesta-5,7,10(19)-triene in which the pro-S hydrogen at position 3 has been replaced by a hydroxy group. It is the inactive form of vitamin D3, being hydroxylated in the liver to calcidiol (25-hydroxyvitamin D3), which is then further hydroxylated in the kidney to give calcitriol (1,25-dihydroxyvitamin D3), the active hormone. It has a role as a human metabolite and a geroprotector. It is a seco-cholestane, a hydroxy seco-steroid, a member of D3 vitamins, a secondary alcohol and a steroid hormone. Vitamin D, in general, is a secosteroid generated in the skin when 7-dehydrocholesterol located there interacts with ultraviolet irradiation - like that commonly found in sunlight. Both the endogenous form of vitamin D (that results from 7-dehydrocholesterol transformation), vitamin D3 (cholecalciferol), and the plant-derived form, vitamin D2 (ergocalciferol), are considered the main forms of vitamin d and are found in various types of food for daily intake. Structurally, ergocalciferol differs from cholecalciferol in that it possesses a double bond between C22 and C23 and has an additional methyl group at C24. Finally, ergocalciferol is pharmacologically less potent than cholecalciferol, which makes vitamin D3 the preferred agent for medical use. Appropriate levels of vitamin D must be upheld in the body in order to maintain calcium and phosphorus levels in a healthy physiologic range to sustain a variety of metabolic functions, transcription regulation, and bone metabolism. However, studies are also ongoing to determine whether or not cholecalciferol may also play certain roles in cancer, autoimmune disorders, cardiovascular disease, and other medical conditions that may be associated with vitamin D deficiency. Cholecalciferol is a Vitamin D. Cholecalciferol is a natural product found in Taiwanofungus camphoratus, Theobroma cacao, and other organisms with data available. Cholecalciferol is a steroid hormone produced in the skin when exposed to ultraviolet light or obtained from dietary sources. The active form of cholecalciferol, 1,25-dihydroxycholecalciferol (calcitriol) plays an important role in maintaining blood calcium and phosphorus levels and mineralization of bone. The activated form of cholecalciferol binds to vitamin D receptors and modulates gene expression. This leads to an increase in serum calcium concentrations by increasing intestinal absorption of phosphorus and calcium, promoting distal renal tubular reabsorption of calcium and increasing osteoclastic resorption. Cholecalciferol is only found in individuals that have used or taken this drug. It is a derivative of 7-dehydroxycholesterol formed by ultraviolet rays breaking of the C9-C10 bond. It differs from ergocalciferol in having a single bond between C22 and C23 and lacking a methyl group at C24. [PubChem]The first step involved in the activation of vitamin D3 is a 25-hydroxylation which is catalysed by the 25-hydroxylase in the liver and then by other enzymes. The mitochondrial sterol 27-hydroxylase catalyses the first reaction in the oxidation of the side chain of sterol intermediates. The active form of vitamin D3 (calcitriol) binds to intracellular receptors that then function as transcription factors to modulate gene expression. Like the receptors for other steroid hormones and thyroid hormones, the vitamin D receptor has hormone-binding and DNA-binding domains. The vitamin D receptor forms a complex with another intracellular receptor, the retinoid-X receptor, and that heterodimer is what binds to DNA. In most cases studied, the effect is to activate transcription, but situations are also known in which vitamin D suppresses transcription. Calcitriol increases the serum calcium concentrations by: increasing GI absorption of phosphorus and calcium, increasing osteoclastic resorption, and increasing distal renal tubula... Vitamin D3, also called cholecalciferol, is one of the forms of vitamin D. Vitamin D3 is a steroid hormone that has long been known for its important role in regulating body levels of calcium and phosphorus, in mineralization of bone, and for the assimilation of Vitamin A. It is structurally similar to steroids such as testosterone, cholesterol, and cortisol (although vitamin D3, itself, is a secosteroid). Vitamin D3 is a derivative of 7-dehydroxycholesterol formed by ultraviolet rays breaking the C9-C10 bond. It differs from ergocalciferol in having a single bond between C22 and C23 and lacking a methyl group at C24. Vitamin D3 can also come from dietary sources, such as beef liver, cheese, egg yolks, and fatty fish (PubChem). The first step involved in the activation of vitamin D3 is a 25-hydroxylation catalyzed by 25-hydroxylase in the liver and then by other enzymes. The mitochondrial sterol 27-hydroxylase catalyzes the first reaction in the oxidation of the side chain of sterol intermediates. The active form of vitamin D3 (calcitriol) binds to intracellular receptors that then function as transcription factors to modulate gene expression. Like the receptors for other steroid hormones and thyroid hormones, the vitamin D receptor has hormone-binding and DNA-binding domains. The vitamin D receptor forms a complex with another intracellular receptor, the retinoid-X receptor, and that heterodimer is what binds to DNA. In most cases studied, the effect is to activate transcription, but situations are also known in which vitamin D suppresses transcription. Calcitriol increases the serum calcium concentrations by (1) increasing GI absorption of phosphorus and calcium, (2) increasing osteoclastic resorption, and (3) increasing distal renal tubular reabsorption of calcium. Calcitriol appears to promote intestinal absorption of calcium through binding to the vitamin D receptor in the mucosal cytoplasm of the intestine. Subsequently, calcium is absorbed through the formation of a calcium-binding protein. Vitamin d, also known as colecalciferol or calciol, belongs to vitamin d and derivatives class of compounds. Those are compounds containing a secosteroid backbone, usually secoergostane or secocholestane. Thus, vitamin d is considered to be a secosteroid lipid molecule. Vitamin d is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Vitamin d can be found in a number of food items such as dumpling, vinegar, chocolate, and margarine, which makes vitamin d a potential biomarker for the consumption of these food products. Vitamin d can be found primarily in blood and urine. Vitamin d is a non-carcinogenic (not listed by IARC) potentially toxic compound. Vitamin d is a drug which is used for the treatment of vitamin d deficiency or insufficiency, refractory rickets (vitamin d resistant rickets), familial hypophosphatemia and hypoparathyroidism, and in the management of hypocalcemia and renal osteodystrophy in patients with chronic renal failure undergoing dialysis. also used in conjunction with calcium in the management and prevention of primary or corticosteroid-induced osteoporosis.

Rutin

C27H30O16 (610.153378)

Rutin is a flavonoid known to have a variety of biological activities including antiallergic, anti-inflammatory, antiproliferative, and anticarcinogenic properties. A large number of flavonoids, mostly O-glycosides, are polyphenolic compounds of natural origin that are present in most fruits and vegetables. The average intake of the compounds by humans on a normal diet is more than 1 g per day. Although flavonoids are devoid of classical nutritional value, they are increasingly viewed as beneficial dietary components that act as potential protectors against human diseases such as coronary heart disease, cancers, and inflammatory bowel disease. Rutin acts as a quercetin deliverer to the large intestine; moreover, quercetin is extensively metabolized in the large intestine, which suggests that quercetin liberated from rutin and/or its colonic metabolites may play a role. Rutins anti-inflammatory actions are mediated through a molecular mechanism that underlies the quercetin-mediated therapeutic effects: quercetin-mediated inhibition of tumor necrosis factor-alpha (TNF-alpha)-induced nuclear factor kappa B (NFkB) activation. TNF-alpha-induced NFkB activity plays a central role in the production of pro-inflammatory mediators involved in progression of gut inflammation. (PMID:16132362). Rutin is a rutinoside that is quercetin with the hydroxy group at position C-3 substituted with glucose and rhamnose sugar groups. It has a role as a metabolite and an antioxidant.

C10H12N4O5 (268.08076619999997)

Inosine, also known as hypoxanthosine or inotin, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Inosine is formed when hypoxanthine is attached to a ribose ring a beta-N9-glycosidic bond. Inosine is an intermediate in the degradation of purines and purine nucleosides to uric acid. Inosine is also an intermediate in the purine salvage pathway. Inosine occurs in the anticodon of certain transfer RNA molecules and is essential for proper translation of the genetic code in wobble base pairs. Inosine exists in all living species, ranging from bacteria to plants to humans. Inosine participates in a number of enzymatic reactions. In particular, inosine can be biosynthesized from inosinic acid through its interaction with the enzyme known as cytosolic purine 5-nucleotidase. In addition, inosine can be converted into hypoxanthine and ribose 1-phosphate through its interaction with the enzyme known as purine nucleoside phosphorylase. Altered levels of inosine have also been associated with purine nucleoside phosphorylase deficiency and xanthinuria type I, both of which are inborn errors of metabolism. Animal studies have suggested that inosine has neuroprotective properties. It has been proposed as a potential treatment for spinal cord injury (PMID: 16317421) and for administration after stroke, as inosine appears to induce axonal rewiring (PMID: 12084941). After ingestion, inosine is metabolized into uric acid, which has been found to be a natural antioxidant and peroxynitrite scavenger. As such, inosine may have potential benefits to patients with multiple sclerosis and Parkinson’s disease (PMID: 19425822). Inosine can also be produced by gut bacteria and appears to have a number of beneficial effects. Inosine, has been shown to activate peroxisome proliferator-activated receptor (PPAR)-gamma signaling in human colon epithelial cells. Furthermore, exogenous treatment of inosine has been found to protect against DSS-induced colitis in rodents by improving adenosine 2A receptor (A2AR)/PPAR-gamma-dependent mucosal barrier functions (PMID: 33820558). Microbiome-derived inosine has also been shown to modulate the response to checkpoint inhibitor immunotherapy in cancer models. In particular, decreased gut barrier function induced by immunotherapy increases systemic translocation of bacterially derived inosine and activates antitumor T cells. The effect of inosine is dependent on T cell expression of the adenosine A2A receptor and requires co-stimulation. Inosine appears to have other roles in non-mammalian system. For instance, it has been found to be an important feed stimulant by itself or in combination with certain amino acids in some species of farmed fish. For example, inosine and inosine-5-monophosphate have been reported as specific feeding stimulants for turbot fry, (Scophthalmus maximus) and Japanese amberjack.

Guanosine

C10H13N5O5 (283.0916648)

Guanosine (G), also known as 2-amino-inosine, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl sugar moiety. Guanosine consists of a guanine base attached to a ribose (ribofuranose) ring via a beta-N9-glycosidic bond. Guanosine is a white, crystalline powder with no odor and mild saline taste. It is very soluble in acetic acid, and slightly soluble in water, but insoluble in ethanol, diethyl ether, benzene, and chloroform. Guanosine exists in all living species, ranging from bacteria to plants to humans. High levels of guanosine can be found in clovers, coffee plants, and the pollen of pines. It has been detected, but not quantified in, several different foods, such as leeks, garlic, chicory roots, green bell peppers, and black-eyed peas. Guanosine plays an important role in various biochemical processes including the synthesis of nucleic acids such as RNA and intracellular signal transduction (cGMP). The antiviral drug acyclovir, often used in herpes treatment, and the anti-HIV drug abacavir, are both structurally similar to guanosine. Guanosine can be phosphorylated to become guanosine monophosphate (GMP), cyclic guanosine monophosphate (cGMP), guanosine diphosphate (GDP), and guanosine triphosphate (GTP). In humans, guanosine is involved in intracellular signalling through the adenosine receptors A1R and A2AR (PMID: 31847113). Evidence from rodent and cell models has shown a number of important neurotrophic and neuroprotective effects of guanosine. In particular, it is effective in preventing deleterious consequences of seizures, spinal cord injury, pain, mood disorders and aging-related diseases, such as ischemia, Parkinson‚Äôs and Alzheimer‚Äôs diseases (PMID: 27699087). Studies with rodent models of Parkinson‚Äôs disease have shown that guanosine decreases neuronal apoptotic cell death and increases dopaminergic neurons at substantia nigra pars compacta, accompanied by an improvement of motor symptoms in Parkinson‚Äôs disease (i.e. a reduction of bradykinesia). Guanosine promotes neurite arborization, outgrowth, proliferation and differentiation. Systemic administration of guanosine for eight weeks (8 mg/kg) has been shown to stimulate neuroprogenitors proliferation in the subventricular zone (SVZ) in a mouse model of Parkinsonism (PMID: 27699087). The effect of guanosine treatment is accompanied by an increased number of fibroblast growth factor (FGF-2)-positive cells which is an important regulator of neuroprogenitor/stem cell proliferation, survival and differentiation (PMID: 27699087). Guanosine prevents reactive oxygen species (ROS) generation and cell death in hippocampal slices subjected to the oxygen/glucose deprivation (PMID: 31847113).

Guanine

C5H5N5O (151.049408)

Guanine is one of the five main nucleobases found in the nucleic acids DNA and RNA. Guanine is a derivative of purine, consisting of a fused pyrimidine-imidazole ring system with conjugated double bonds. Being unsaturated, the bicyclic molecule is planar. The guanine nucleoside is called guanosine. The first isolation of guanine was reported in 1844 from the excreta of sea birds, known as guano, which was used as a source of fertilizer. High affinity binding of guanine nucleotides and the ability to hydrolyze bound GTP to GDP are characteristics of an extended family of intracellular proteins. Guanine nucleotide-binding regulatory proteins may be involved in the activation of phospholipases C and A2 by hormones and other ligands. The binding of hormones to receptors that activate phospholipase C is decreased by guanine nucleotides and these hormones also stimulate a high-affinity GTPase activity in cell membranes. Effects of hormones on phospholipase C activity in cell-free preparations are dependent on the presence of guanine nucleotides. Hypoxanthine-guanine phosphoribosyltransferase (HPRT, EC 2.4.2.8) is a purine salvage enzyme that catalyses the conversion of hypoxanthine and guanine to their respective mononucleotides. Partial deficiency of this enzyme can result in the overproduction of uric acid leading to a severe form of gout, whilst a virtual absence of HPRT activity causes the Lesch-Nyhan syndrome, an inborn error of metabolism, which is characterised by hyperuricaemia, mental retardation, choreoathetosis and compulsive self-mutilation. Peroxynitrite induces DNA base damage predominantly at guanine (G) and 8-oxoguanine (8-oxoG) nucleobases via oxidation reactions. G and 8-oxoG are the most reactive bases toward Peroxynitrite and possibly the major contributors to peroxynitrite-derived genotoxic and mutagenic lesions. The neutral G radical, reacts with NO2 to yield 8-nitroguanine and 5-nitro-4-guanidinohydantoin (PMID: 16352449, 2435586, 2838362, 1487231). Guanine is a 2-aminopurine carrying a 6-oxo substituent. It has a role as a human metabolite, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite.

L-Leucine

C6H13NO2 (131.0946238)

Leucine (Leu) or L-leucine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (‚ÄìNH2) and carboxyl (‚ÄìCOOH) functional groups, along with a side chain (R group) specific to each amino acid. L-leucine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Leucine is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aliphatic amino acid. Leucine is essential in humans, meaning the body cannot synthesize it, and it must be obtained from the diet. Human dietary sources are foods that contain protein, such as meats, dairy products, soy products, beans and legumes. L-Leucine is a branched chain amino acid (BCAA). The BCAAs consist of leucine, valine and isoleucine (and occasionally threonine). BCAAs are essential amino acids whose carbon structure is marked by a branch point at the beta-carbon position. BCAAs are critical to human life and are particularly involved in stress, energy and muscle metabolism. BCAA supplementation as therapy, both oral and intravenous, in human health and disease holds great promise. BCAAs have different metabolic routes, with valine going solely to carbohydrates (glucogenic), leucine solely to fats (ketogenic) and isoleucine being both a glucogenic and a ketogenic amino acid. The different metabolism accounts for different requirements for these essential amino acids in humans: 12 mg/kg, 14 mg/kg and 16 mg/kg of valine, leucine and isoleucine respectively. The primary metabolic end products of leucine metabolism are acetyl-CoA and acetoacetate; consequently, it is one of the two exclusively ketogenic amino acids, with lysine being the other. Leucine is the most important ketogenic amino acid in humans. The vast majority of l-leucine metabolism is initially catalyzed by the branched-chain amino acid aminotransferase enzyme, producing alpha-ketoisocaproate (alpha-KIC). alpha-KIC is metabolized by the mitochondrial enzyme branched-chain alpha-ketoacid dehydrogenase, which converts it to isovaleryl-CoA. Isovaleryl-CoA is subsequently metabolized by the enzyme isovaleryl-CoA dehydrogenase and converted to beta-methylcrotonyl-CoA (MC-CoA), which is used in the synthesis of acetyl-CoA and other compounds. During biotin deficiency, HMB can be synthesized from MC-CoA via enoyl-CoA hydratase and an unknown thioesterase enzyme, which convert MC-CoA into HMB-CoA and HMB-CoA into HMB respectively. Leucine has the capacity to directly stimulate myofibrillar muscle protein synthesis (PMID 15051860). This effect of leucine arises results from its role as an activator of the mechanistic target of rapamycin (mTOR) (PMID 23551944) a serine-threonine protein kinase that regulates protein biosynthesis and cell growth. The activation of mTOR by leucine is mediated through Rag GTPases. Leucine, like other BCAAs, is associated with insulin resistance. In particular, higher levels of leucine are observed in the blood of diabetic mice, rats, and humans (PMID 25287287). BCAAs such as leucine have different deficiency symptoms. Valine deficiency is marked by neurological defects in the brain, while isoleucine deficiency is marked by muscle tremors. Persistently low leucine levels can result in decreased appetite, poor feeding, lethargy, poor growth, weight loss, skin rashes, hair loss, and desquamation. Many types of inborn errors of BCAA metabolism exist and these are marked by various abnormalities. The most common form is maple syrup urine disease, marked by a characteristic urinary odor. Other abnormalities are associated with a wide range of symptoms, such as mental retardation, ataxia, hypoglycemia, spinal muscle atrophy, rash, vomiting and excessive muscle movement. Most forms of BCAA metabolism errors are corrected by dietary res... L-leucine is the L-enantiomer of leucine. It has a role as a plant metabolite, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite, a human metabolite, an algal metabolite and a mouse metabolite.

L-Leucine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Leucine is one of nine essential amino acids in humans (provided by food), Leucine is important for protein synthesis and many metabolic functions. Leucine contributes to regulation of blood-sugar levels; growth and repair of muscle and bone tissue; growth hormone production; and wound healing. Leucine also prevents breakdown of muscle proteins after trauma or severe stress and may be beneficial for individuals with phenylketonuria. Leucine is available in many foods and deficiency is rare. (NCI04) Leucine (abbreviated as Leu or L)[2] is a branched-chain л±-amino acid with the chemical formulaHO2CCH(NH2)CH2CH(CH3)2. Leucine is classified as a hydrophobic amino acid due to its aliphatic isobutyl side chain. It is encoded by six codons (UUA, UUG, CUU, CUC, CUA, and CUG) and is a major component of the subunits in ferritin, astacin, and other buffer proteins.

Caffeic acid

C9H8O4 (180.0422568)

Caffeic acid is a hydroxycinnamic acid that is cinnamic acid in which the phenyl ring is substituted by hydroxy groups at positions 3 and 4. It exists in cis and trans forms; the latter is the more common. It has a role as a plant metabolite, an EC 1.13.11.33 (arachidonate 15-lipoxygenase) inhibitor, an EC 2.5.1.18 (glutathione transferase) inhibitor, an EC 1.13.11.34 (arachidonate 5-lipoxygenase) inhibitor, an antioxidant and an EC 3.5.1.98 (histone deacetylase) inhibitor. It is a hydroxycinnamic acid and a member of catechols. Caffeic Acid is a natural product found in Pavetta indica, Eupatorium cannabinum, and other organisms with data available. Caffeic Acid is an orally bioavailable, hydroxycinnamic acid derivative and polyphenol, with potential anti-oxidant, anti-inflammatory, and antineoplastic activities. Upon administration, caffeic acid acts as an antioxidant and prevents oxidative stress, thereby preventing DNA damage induced by free radicals. Caffeic acid targets and inhibits the histone demethylase (HDM) oncoprotein gene amplified in squamous cell carcinoma 1 (GASC1; JMJD2C; KDM4C) and inhibits cancer cell proliferation. GASC1, a member of the KDM4 subgroup of Jumonji (Jmj) domain-containing proteins, demethylates trimethylated lysine 9 and lysine 36 on histone H3 (H3K9 and H3K36), and plays a key role in tumor cell development.

Uridine

C9H12N2O6 (244.0695332)

Uridine, also known as beta-uridine or 1-beta-D-ribofuranosylpyrimidine-2,4(1H,3H)-dione, is a member of the class of compounds known as pyrimidine nucleosides. Pyrimidine nucleosides are compounds comprising a pyrimidine base attached to a ribosyl or deoxyribosyl moiety. More specifically, uridine is a nucleoside consisting of uracil and D-ribose and a component of RNA. Uridine is soluble (in water) and a very weakly acidic compound (based on its pKa). Uridine can be synthesized from uracil. It is one of the five standard nucleosides which make up nucleic acids, the others being adenosine, thymidine, cytidine and guanosine. The five nucleosides are commonly abbreviated to their one-letter codes U, A, T, C and G respectively. Uridine is also a parent compound for other transformation products, including but not limited to, nikkomycin Z, 3-(enolpyruvyl)uridine 5-monophosphate, and 5-aminomethyl-2-thiouridine. Uridine can be found in most biofluids, including urine, breast milk, cerebrospinal fluid (CSF), and blood. Within the cell, uridine is primarily located in the mitochondria, in the nucleus and the lysosome. It can also be found in the extracellular space. As an essential nucleoside, uridine exists in all living species, ranging from bacteria to humans. In humans, uridine is involved in several metabolic disorders, some of which include dhydropyrimidinase deficiency, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and beta-ureidopropionase deficiency. Moreover, uridine is found to be associated with Lesch-Nyhan syndrome, which is an inborn error of metabolism. Uridine is a nucleoside consisting of uracil and D-ribose and a component of RNA. Uridine plays a role in the glycolysis pathway of galactose. In humans there is no catabolic process to metabolize galactose. Therefore, galactose is converted to glucose and metabolized via the normal glucose metabolism pathways. More specifically, consumed galactose is converted into galactose 1-phosphate (Gal-1-P). This molecule is a substrate for the enzyme galactose-1-phosphate uridyl transferase which transfers a UDP molecule to the galactose molecule. The end result is UDP-galactose and glucose-1-phosphate. This process is continued to allow the proper glycolysis of galactose. Uridine is found in many foods (anything containing RNA) but is destroyed in the liver and gastrointestinal tract, and so no food, when consumed, has ever been reliably shown to elevate blood uridine levels. On the other hand, consumption of RNA-rich foods may lead to high levels of purines (adenine and guanosine) in blood. High levels of purines are known to increase uric acid production and may aggravate or lead to conditions such as gout. Uridine is a ribonucleoside composed of a molecule of uracil attached to a ribofuranose moiety via a beta-N(1)-glycosidic bond. It has a role as a human metabolite, a fundamental metabolite and a drug metabolite. It is functionally related to a uracil. Uridine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Uridine is a Pyrimidine Analog. The chemical classification of uridine is Pyrimidines, and Analogs/Derivatives. Uridine is a natural product found in Ulva australis, Synechocystis, and other organisms with data available. Uridine is a nucleoside consisting of uracil and D-ribose and a component of RNA.

L-Proline

C5H9NO2 (115.0633254)

Proline (Pro), also known as L-proline is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. Proline is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Proline is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, non-polar amino acid. Proline is sometimes called an imino acid, although the IUPAC definition of an imine requires a carbon-nitrogen double bond. Proline is a non-essential amino acid that is synthesized from glutamic acid. It is an essential component of collagen and is important for proper functioning of joints and tendons. Proline is derived from the amino acid L-glutamate in which glutamate-5-semialdehyde is first formed by glutamate 5-kinase and glutamate-5-semialdehyde dehydrogenase (which requires NADH or NADPH). This semialdehyde can then either spontaneously cyclize to form 1-pyrroline-5-carboxylic acid, which is reduced to proline by pyrroline-5-carboxylate reductase, or turned into ornithine by ornithine aminotransferase, followed by cyclization by ornithine cyclodeaminase to form proline. L-Proline has been found to act as a weak agonist of the glycine receptor and of both NMDA and non-NMDA ionotropic glutamate receptors. It has been proposed to be a potential endogenous excitotoxin/neurotoxin. Studies in rats have shown that when injected into the brain, proline non-selectively destroys pyramidal and granule cells (PMID: 3409032 ). Therefore, under certain conditions proline can act as a neurotoxin and a metabotoxin. A neurotoxin causes damage to nerve cells and nerve tissues. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of proline are associated with at least five inborn errors of metabolism, including hyperprolinemia type I, hyperprolinemia type II, iminoglycinuria, prolinemia type II, and pyruvate carboxylase deficiency. People with hyperprolinemia type I often do not show any symptoms even though they have proline levels in their blood between 3 and 10 times the normal level. Some individuals with hyperprolinemia type I exhibit seizures, intellectual disability, or other neurological or psychiatric problems. Hyperprolinemia type II results in proline levels in the blood between 10 and 15 times higher than normal, and high levels of a related compound called pyrroline-5-carboxylate. Hyperprolinemia type II has signs and symptoms that vary in severity and is more likely than type I to involve seizures or intellectual disability. L-proline is pyrrolidine in which the pro-S hydrogen at position 2 is substituted by a carboxylic acid group. L-Proline is the only one of the twenty DNA-encoded amino acids which has a secondary amino group alpha to the carboxyl group. It is an essential component of collagen and is important for proper functioning of joints and tendons. It also helps maintain and strengthen heart muscles. It has a role as a micronutrient, a nutraceutical, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a mouse metabolite and a member of compatible osmolytes. It is a glutamine family amino acid, a proteinogenic amino acid, a proline and a L-alpha-amino acid. It is a conjugate base of a L-prolinium. It is a conjugate acid of a L-prolinate. It is an enantiomer of a D-proline. It is a tautomer of a L-proline zwitterion. Proline is one of the twenty amino acids used in living organisms as the building blocks of proteins. Proline is sometimes called an imino acid, although the IUPAC definition of an imine requires a carbon-nitrogen double bond. Proline is a non-essential amino acid that is synthesized from glutamic acid. It is an essential component of collagen and is important for proper functioning of joints and tendons. L-Proline is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Proline is a cyclic, nonessential amino acid (actually, an imino acid) in humans (synthesized from glutamic acid and other amino acids), Proline is a constituent of many proteins. Found in high concentrations in collagen, proline constitutes almost a third of the residues. Collagen is the main supportive protein of skin, tendons, bones, and connective tissue and promotes their health and healing.

Trans-4-hydroxyproline

C5H9NO3 (131.0582404)

Trans-4-hydroxy-L-proline is an optically active form of 4-hydroxyproline having L-trans-configuration. It has a role as a human metabolite, a plant metabolite and a mouse metabolite. It is a tautomer of a trans-4-hydroxy-L-proline zwitterion. Hydroxyproline is a neutral heterocyclic protein amino acid. It is found in collagen and as such it is common in many gelatin products. Hydroxyproline is mostly used as a diagnostic marker of bone turnover and liver fibrosis. Therapeutically, hydroxyproline is being studied as an an experimental medicine but is approved in France as a combination topical gel product called Cicactive for small, superficial wounds. Hydroxyproline is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Hydroxyproline is a nonessential amino acid derivative formed during post-translational protein modification through hydroxylation of the amino acid proline by the enzyme prolyl hydroxylase which requires vitamin C as a co-factor. Hydroxyproline is a major component of the protein collagen and plays a key role in the stability of the collagen triple helix. It can be used as an indicator to determine the amount of collagen. Increased hydroxyproline levels in the urine and/or serum are normally associated with degradation of connective tissue. Vitamin C deficiency decreases the conversion of proline to hydroxyproline, which leads to reduced collagen stability. 4-Hydroxyproline (or hydroxyproline or Hyp) is a major component of the protein collagen. Hydroxyproline is produced by hydroxylation of the amino acid proline and is, therefore, a post-translationally modified amino acid. Hydroxyproline and proline play key roles for collagen stability. In particular, they permit the sharp twisting of the collagen helix. Hydroxyproline is found in few proteins other than collagen. The only other mammalian protein which includes hydroxyproline is elastin. For this reason, hydroxyproline content has been used as an indicator to determine collagen and/or gelatin amount in tissue or biological samples.

Taurine

C2H7NO3S (125.0146632)

Essential nutrient obtained from diet and by in vivo synthysis from methionine and cysteine. Present in meats, fish, legumes, human milk, molluscs and other foods. Dietary supplement, e.g. in Red Bull drink. Taurine is a sulfur amino acid like methionine, cystine, cysteine and homocysteine. It is a lesser-known amino acid because it is not incorporated into the structural building blocks of protein. Yet taurine is an essential amino acid in pre-term and newborn infants of humans and many other species. Adults can synthesize their own taurine, yet are probably dependent in part on dietary taurine. Taurine is abundant in the brain, heart, breast, gallbladder and kidney and has important roles in health and disease in these organs. Taurine has many diverse biological functions serving as a neurotransmitter in the brain, a stabilizer of cell membranes and a facilitator in the transport of ions such as sodium, potassium, calcium and magnesium. Taurine is highly concentrated in animal and fish protein, which are good sources of dietary taurine. It can be synthesized by the body from cysteine when vitamin B6 is present. Deficiency of taurine occurs in premature infants and neonates fed formula milk, and in various disease states. Inborn errors of taurine metabolism have been described. OMIM 168605, an unusual neuropsychiatric disorder inherited in an autosomal dominant fashion through 3 generations of a family. Symptoms began late in the fifth decade in 6 affected persons and death occurred after 4 to 6 years. The earliest and most prominent symptom was mental depression not responsive to antidepressant drugs or electroconvulsive therapy. Sleep disturbances, exhaustion and marked weight loss were features. Parkinsonism developed later, and respiratory failure occurred terminally. OMIM 145350 describes congestive cardiomyopathy and markedly elevated urinary taurine levels (about 5 times normal). Other family members had late or holosystolic mitral valve prolapse and elevated urinary taurine values (about 2.5 times normal). In 2 with mitral valve prolapse, congestive cardiomyopathy eventually developed while the amounts of urinary taurine doubled. Taurine, after GABA, is the second most important inhibitory neurotransmitter in the brain. Its inhibitory effect is one source of taurines anticonvulsant and antianxiety properties. It also lowers glutamic acid in the brain, and preliminary clinical trials suggest taurine may be useful in some forms of epilepsy. Taurine in the brain is usually associated with zinc or manganese. The amino acids alanine and glutamic acid, as well as pantothenic acid, inhibit taurine metabolism while vitamins A and B6, zinc and manganese help build taurine. Cysteine and B6 are the nutrients most directly involved in taurine synthesis. Taurine levels have been found to decrease significantly in many depressed patients. One reason that the findings are not entirely clear is because taurine is often elevated in the blood of epileptics who need it. It is often difficult to distinguish compensatory changes in human biochemistry from true metabolic or deficiency disease. Low levels of taurine are found in retinitis pigmentosa. Taurine deficiency in experimental animals produces degeneration of light-sensitive cells. Therapeutic applications of taurine to eye disease are likely to be forthcoming. Taurine has many important metabolic roles. Supplements can stimulate prolactin and insulin release. The parathyroid gland makes a peptide hormone called glutataurine (glutamic acid-taurine), which further demonstrates taurines role in endocrinology. Taurine increases bilirubin and cholesterol excretion in bile, critical to normal gallbladder function. It seems to inhibit the effect of morphine and potentiates the effects of opiate antagonists.

Maleic acid

C4H4O4 (116.01095839999999)

Maleic acid is a colorless crystalline solid having a faint odor. It is combustible though it may take some effort to ignite. It is soluble in water. It is used to make other chemicals and for dyeing and finishing naturally occurring fibers. Maleic acid is a butenedioic acid in which the double bond has cis- (Z)-configuration. It has a role as a plant metabolite, an algal metabolite and a mouse metabolite. It is a conjugate acid of a maleate(1-) and a maleate. Maleic acid is a natural product found in Populus tremula, Ardisia crenata, and other organisms with data available. Maleic Acid is an organic salt or ester of maleic acid that could be conjugated to free base compounds/drugs to improve the physiochemical properties including stability, solubility and dissolution rate. (NCI) Maleic acid is an industrial raw material for the production of glyoxylic acid by ozonolysis. Maleic acid is an organic compound which is a dicarboxylic acid (molecule with two carboxyl groups). The molecule consists of an ethylene group flanked by two carboxylic acid groups. Maleic acid is the cis isomer of butenedioic acid, whereas fumaric acid is the trans isomer. The cis isomer is the less stable one of the two; the difference in heat of combustion is 22.7 kJ/mol. The physical properties of maleic acid are very different from that of fumaric acid. Maleic acid is soluble in water whereas fumaric acid is not and the melting point of maleic acid (130 - 131 degree centigrade) is also much lower than that of fumaric acid (287 degree centigrade). Both properties of maleic acid can be explained on account of the intramolecular hydrogen bonding that takes place at the expense of intermolecular interactions. Maleic acid is converted into maleic anhydride by dehydration, to malic acid by hydration, and to succinic acid by hydrogenation.

Citric acid

C6H8O7 (192.0270018)

Citric acid (citrate) is a tricarboxylic acid, an organic acid with three carboxylate groups. Citrate is an intermediate in the TCA cycle (also known as the Tricarboxylic Acid cycle, the Citric Acid cycle or Krebs cycle). The TCA cycle is a central metabolic pathway for all animals, plants, and bacteria. As a result, citrate is found in all living organisms, from bacteria to plants to animals. In the TCA cycle, the enzyme citrate synthase catalyzes the condensation of oxaloacetate with acetyl CoA to form citrate. Citrate then acts as the substrate for the enzyme known as aconitase and is then converted into aconitic acid. The TCA cycle ends with regeneration of oxaloacetate. This series of chemical reactions in the TCA cycle is the source of two-thirds of the food-derived energy in higher organisms. Citrate can be transported out of the mitochondria and into the cytoplasm, then broken down into acetyl-CoA for fatty acid synthesis, and into oxaloacetate. Citrate is a positive modulator of this conversion, and allosterically regulates the enzyme acetyl-CoA carboxylase, which is the regulating enzyme in the conversion of acetyl-CoA into malonyl-CoA (the commitment step in fatty acid synthesis). In short, citrate is transported into the cytoplasm, converted into acetyl CoA, which is then converted into malonyl CoA by acetyl CoA carboxylase, which is allosterically modulated by citrate. In mammals and other vertebrates, Citrate is a vital component of bone, helping to regulate the size of apatite crystals (PMID: 21127269). Citric acid is found in citrus fruits, most concentrated in lemons and limes, where it can comprise as much as 8\\\\\% of the dry weight of the fruit. Citric acid is a natural preservative and is also used to add an acidic (sour) taste to foods and carbonated drinks. Because it is one of the stronger edible acids, the dominant use of citric acid is as a flavoring and preservative in food and beverages, especially soft drinks and candies. Citric acid is an excellent chelating agent, binding metals by making them soluble. It is used to remove and discourage the buildup of limescale from boilers and evaporators. It can be used to treat water, which makes it useful in improving the effectiveness of soaps and laundry detergents. The salts of citric acid (citrates) can be used as anticoagulants due to their calcium chelating ability. Intolerance to citric acid in the diet is known to exist. Little information is available as the condition appears to be rare, but like other types of food intolerance it is often described as a "pseudo-allergic" reaction. Citric acid appears as colorless, odorless crystals with an acid taste. Denser than water. (USCG, 1999) Citric acid is a tricarboxylic acid that is propane-1,2,3-tricarboxylic acid bearing a hydroxy substituent at position 2.

The salts of citric acid (citrates) can be used as anticoagulants due to their calcium chelating ability. See also: Citric Acid Monohydrate (related). Citrate, also known as anhydrous citric acid or 2-hydroxy-1,2,3-propanetricarboxylic acid, belongs to tricarboxylic acids and derivatives class of compounds. Those are carboxylic acids containing exactly three carboxyl groups. Citrate is soluble (in water) and a weakly acidic compound (based on its pKa). Citrate can be found in a number of food items such as ucuhuba, loquat, bayberry, and longan, which makes citrate a potential biomarker for the consumption of these food products. Citrate can be found primarily in most biofluids, including saliva, sweat, feces, and blood, as well as throughout all human tissues. Citrate exists in all living species, ranging from bacteria to humans. In humans, citrate is involved in several metabolic pathways, some of which include the oncogenic action of succinate, the oncogenic action of fumarate, the oncogenic action of 2-hydroxyglutarate, and congenital lactic acidosis. Citrate is also involved in several metabolic disorders, some of which include 2-ketoglutarate dehydrogenase complex deficiency, pyruvate dehydrogenase deficiency (E2), fumarase deficiency, and glutaminolysis and cancer. Moreover, citrate is found to be associated with lung Cancer, tyrosinemia I, maple syrup urine disease, and propionic acidemia. A citrate is a derivative of citric acid; that is, the salts, esters, and the polyatomic anion found in solution. An example of the former, a salt is trisodium citrate; an ester is triethyl citrate. When part of a salt, the formula of the citrate ion is written as C6H5O73− or C3H5O(COO)33− .

Cytosine

C4H5N3O (111.04326000000002)

Cytosine, also known as C, belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Cytosine is also classified as a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2). Cytosine is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). The nucleoside of cytosine is cytidine. In Watson-Crick base pairing, cytosine forms three hydrogen bonds with guanine. Cytosine was discovered and named by Albrecht Kossel and Albert Neumann in 1894 when it was hydrolyzed from calf thymus tissues. Cytosine exists in all living species, ranging from bacteria to plants to humans. Within cells, cytosine can undergo several enzymatic reactions. It can be methylated into 5-methylcytosine by an enzyme called DNA methyltransferase (DNMT) or be methylated and hydroxylated to make 5-hydroxymethylcytosine. The DNA methyltransferase (DNMT) family of enzymes transfer a methyl group from S-adenosyl-l-methionine (SAM) to the 5’ carbon of cytosine in a molecule of DNA. High levels of cytosine can be found in the urine of individuals with severe combined immunodeficiency syndrome (SCID).

A fumarate is a salt or ester of the organic compound fumaric acid, a dicarboxylic acid. Fumarate has recently been recognized as an oncometabolite. (A15199). As a food additive, fumaric acid is used to impart a tart taste to processed foods. It is also used as an antifungal agent in boxed foods such as cake mixes and flours, as well as tortillas. Fumaric acid is also added to bread to increase the porosity of the final baked product. It is used to impart a sour taste to sourdough and rye bread. In cake mixes, it is used to maintain a low pH and prevent clumping of the flours used in the mix. In fruit drinks, fumaric acid is used to maintain a low pH which, in turn, helps to stabilize flavor and color. Fumaric acid also prevents the growth of E. coli in beverages when used in combination with sodium benzoate. When added to wines, fumaric acid helps to prevent further fermentation and yet maintain low pH and eliminate traces of metallic elements. In this fashion, it helps to stabilize the taste of wine. Fumaric acid can also be added to dairy products, sports drinks, jams, jellies and candies. Fumaric acid helps to break down bonds between gluten proteins in wheat and helps to create a more pliable dough. Fumaric acid is used in paper sizing, printer toner, and polyester resin for making molded walls. Fumaric acid is a dicarboxylic acid. It is a precursor to L-malate in the Krebs tricarboxylic acid (TCA) cycle. It is formed by the oxidation of succinic acid by succinate dehydrogenase. Fumarate is converted by the enzyme fumarase to malate. Fumaric acid has recently been identified as an oncometabolite or an endogenous, cancer causing metabolite. High levels of this organic acid can be found in tumors or biofluids surrounding tumors. Its oncogenic action appears to due to its ability to inhibit prolyl hydroxylase-containing enzymes. In many tumours, oxygen availability becomes limited (hypoxia) very quickly due to rapid cell proliferation and limited blood vessel growth. The major regulator of the response to hypoxia is the HIF transcription factor (HIF-alpha). Under normal oxygen levels, protein levels of HIF-alpha are very low due to constant degradation, mediated by a series of post-translational modification events catalyzed by the prolyl hydroxylase domain-containing enzymes PHD1, 2 and 3, (also known as EglN2, 1 and 3) that hydroxylate HIF-alpha and lead to its degradation. All three of the PHD enzymes are inhibited by fumarate. Fumaric acid is found to be associated with fumarase deficiency, which is an inborn error of metabolism. It is also a metabolite of Aspergillus. Produced industrially by fermentation of Rhizopus nigricans, or manufactured by catalytic or thermal isomerisation of maleic anhydride or maleic acid. Used as an antioxidant, acidulant, leavening agent and flavouring agent in foods. Present in raw lean fish. Dietary supplement. Used in powdered products since fumaric acid is less hygroscopic than other acids. A precursor to L-malate in the Krebs tricarboxylic acid cycle. It is formed by the oxidation of succinate by succinate dehydrogenase (wikipedia). Fumaric acid is also found in garden tomato, papaya, wild celery, and star fruit. Fumaric acid.

L-Glutamic acid

C5H9NO4 (147.0531554)

Glutamic acid (Glu), also known as L-glutamic acid or as glutamate, the name of its anion, is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (‚ÄìNH2) and carboxyl (‚ÄìCOOH) functional groups, along with a side chain (R group) specific to each amino acid. L-glutamic acid is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Glutamic acid is found in all organisms ranging from bacteria to plants to animals. It is classified as an acidic, charged (at physiological pH), aliphatic amino acid. In humans it is a non-essential amino acid and can be synthesized via alanine or aspartic acid via alpha-ketoglutarate and the action of various transaminases. Glutamate also plays an important role in the bodys disposal of excess or waste nitrogen. Glutamate undergoes deamination, an oxidative reaction catalysed by glutamate dehydrogenase leading to alpha-ketoglutarate. In many respects glutamate is a key molecule in cellular metabolism. Glutamate is the most abundant fast excitatory neurotransmitter in the mammalian nervous system. At chemical synapses, glutamate is stored in vesicles. Nerve impulses trigger release of glutamate from the pre-synaptic cell. In the opposing post-synaptic cell, glutamate receptors, such as the NMDA receptor, bind glutamate and are activated. Because of its role in synaptic plasticity, it is believed that glutamic acid is involved in cognitive functions like learning and memory in the brain. Glutamate transporters are found in neuronal and glial membranes. They rapidly remove glutamate from the extracellular space. In brain injury or disease, they can work in reverse and excess glutamate can accumulate outside cells. This process causes calcium ions to enter cells via NMDA receptor channels, leading to neuronal damage and eventual cell death, and is called excitotoxicity. The mechanisms of cell death include: Damage to mitochondria from excessively high intracellular Ca2+. Glu/Ca2+-mediated promotion of transcription factors for pro-apoptotic genes, or downregulation of transcription factors for anti-apoptotic genes. Excitotoxicity due to glutamate occurs as part of the ischemic cascade and is associated with stroke and diseases like amyotrophic lateral sclerosis, lathyrism, and Alzheimers disease. Glutamic acid has been implicated in epileptic seizures. Microinjection of glutamic acid into neurons produces spontaneous depolarization around one second apart, and this firing pattern is similar to what is known as paroxysmal depolarizing shift in epileptic attacks. This change in the resting membrane potential at seizure foci could cause spontaneous opening of voltage activated calcium channels, leading to glutamic acid release and further depolarization (http://en.wikipedia.org/wiki/Glutamic_acid). Glutamate was discovered in 1866 when it was extracted from wheat gluten (from where it got its name. Glutamate has an important role as a food additive and food flavoring agent. In 1908, Japanese researcher Kikunae Ikeda identified brown crystals left behind after the evaporation of a large amount of kombu broth (a Japanese soup) as glutamic acid. These crystals, when tasted, reproduced a salty, savory flavor detected in many foods, most especially in seaweed. Professor Ikeda termed this flavor umami. He then patented a method of mass-producing a crystalline salt of glutamic acid, monosodium glutamate. L-glutamic acid is an optically active form of glutamic acid having L-configuration. It has a role as a nutraceutical, a micronutrient, an Escherichia coli metabolite, a mouse metabolite, a ferroptosis inducer and a neurotransmitter. It is a glutamine family amino acid, a proteinogenic amino acid, a glutamic acid and a L-alpha-amino acid. It is a conjugate acid of a L-glutamate(1-). It is an enantiomer of a D-glutamic acid. A peptide that is a homopolymer of glutamic acid. L-Glutamic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Glutamic acid (Glu), also referred to as glutamate (the anion), is one of the 20 proteinogenic amino acids. It is not among the essential amino acids. Glutamate is a key molecule in cellular metabolism. In humans, dietary proteins are broken down by digestion into amino acids, which serves as metabolic fuel or other functional roles in the body. Glutamate is the most abundant fast excitatory neurotransmitter in the mammalian nervous system. At chemical synapses, glutamate is stored in vesicles. Nerve impulses trigger release of glutamate from the pre-synaptic cell. In the opposing post-synaptic cell, glutamate receptors, such as the NMDA receptor, bind glutamate and are activated.

Since 1965 the industrial source of glutamic acid for MSG production has been bacterial fermentation of carbohydrate sources such as molasses and corn starch hydrolysate in the presence of a nitrogen source such as ammonium salts or urea. Annual production approx. 350000t worldwide in 1988. Seasoning additive in food manuf. (as Na, K and NH4 salts). Dietary supplement, nutrient Glutamic acid (symbol Glu or E;[4] the anionic form is known as glutamate) is an α-amino acid that is used by almost all living beings in the biosynthesis of proteins. It is a non-essential nutrient for humans, meaning that the human body can synthesize enough for its use. It is also the most abundant excitatory neurotransmitter in the vertebrate nervous system. It serves as the precursor for the synthesis of the inhibitory gamma-aminobutyric acid (GABA) in GABAergic neurons. Its molecular formula is C 5H 9NO 4. Glutamic acid exists in two optically isomeric forms; the dextrorotatory l-form is usually obtained by hydrolysis of gluten or from the waste waters of beet-sugar manufacture or by fermentation.[5][full citation needed] Its molecular structure could be idealized as HOOC−CH(NH 2)−(CH 2)2−COOH, with two carboxyl groups −COOH and one amino group −NH 2. However, in the solid state and mildly acidic water solutions, the molecule assumes an electrically neutral zwitterion structure −OOC−CH(NH+ 3)−(CH 2)2−COOH. It is encoded by the codons GAA or GAG. The acid can lose one proton from its second carboxyl group to form the conjugate base, the singly-negative anion glutamate −OOC−CH(NH+ 3)−(CH 2)2−COO−. This form of the compound is prevalent in neutral solutions. The glutamate neurotransmitter plays the principal role in neural activation.[6] This anion creates the savory umami flavor of foods and is found in glutamate flavorings such as MSG. In Europe, it is classified as food additive E620. In highly alkaline solutions the doubly negative anion −OOC−CH(NH 2)−(CH 2)2−COO− prevails. The radical corresponding to glutamate is called glutamyl. The one-letter symbol E for glutamate was assigned in alphabetical sequence to D for aspartate, being larger by one methylene –CH2– group.[7] DL-Glutamic acid is the conjugate acid of Glutamic acid, which acts as a fundamental metabolite. Comparing with the second phase of polymorphs α and β L-Glutamic acid, DL-Glutamic acid presents better stability[1].

4-Hydroxybenzoic acid

C7H6O3 (138.03169259999999)

4-Hydroxybenzoic acid, also known as p-hydroxybenzoate or 4-carboxyphenol, belongs to the class of organic compounds known as hydroxybenzoic acid derivatives. Hydroxybenzoic acid derivatives are compounds containing a hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxyl and a hydroxyl groups. 4-Hydroxybenzoic acid is a white crystalline solid that is slightly soluble in water and chloroform but more soluble in polar organic solvents such as alcohols and acetone. It is a nutty and phenolic tasting compound. 4-Hydroxybenzoic acid exists in all living species, ranging from bacteria to plants to humans. 4-Hydroxybenzoic acid can be found naturally in coconut. It is one of the main catechins metabolites found in humans after consumption of green tea infusions. It is also found in wine, in vanilla, in A√ßa√≠ oil, obtained from the fruit of the a√ßa√≠ palm (Euterpe oleracea), at relatively high concetrations (892¬±52 mg/kg). It is also found in cloudy olive oil and in the edible mushroom Russula virescens. It has been detected in red huckleberries, rabbiteye blueberries, and corianders and in a lower concentration in olives, red raspberries, and almonds. In humans, 4-hydroxybenzoic acid is involved in ubiquinone biosynthesis. In particular, the enzyme 4-hydroxybenzoate polyprenyltransferase uses a polyprenyl diphosphate and 4-hydroxybenzoate to produce diphosphate and 4-hydroxy-3-polyprenylbenzoate. This enzyme participates in ubiquinone biosynthesis. 4-Hydroxybenzoic acid can be biosynthesized by the enzyme Chorismate lyase. Chorismate lyase is an enzyme that transforms chorismate into 4-hydroxybenzoate and pyruvate. This enzyme catalyses the first step in ubiquinone biosynthesis in Escherichia coli and other Gram-negative bacteria. 4-Hydroxybenzoate is an intermediate in many enzyme-mediated reactions in microbes. For instance, the enzyme 4-hydroxybenzaldehyde dehydrogenase uses 4-hydroxybenzaldehyde, NAD+ and H2O to produce 4-hydroxybenzoate, NADH and H+. This enzyme participates in toluene and xylene degradation in bacteria such as Pseudomonas mendocina. 4-hydroxybenzaldehyde dehydrogenase is also found in carrots. The enzyme 4-hydroxybenzoate 1-hydroxylase transforms 4-hydroxybenzoate, NAD(P)H, 2 H+ and O2 into hydroquinone, NAD(P)+, H2O and CO2. This enzyme participates in 2,4-dichlorobenzoate degradation and is found in Candida parapsilosis. The enzyme 4-hydroxybenzoate 3-monooxygenase transforms 4-hydroxybenzoate, NADPH, H+ and O2 into protocatechuate, NADP+ and H2O. This enzyme participates in benzoate degradation via hydroxylation and 2,4-dichlorobenzoate degradation and is found in Pseudomonas putida and Pseudomonas fluorescens. 4-Hydroxybenzoic acid is a popular antioxidant in part because of its low toxicity. 4-Hydroxybenzoic acid has estrogenic activity both in vitro and in vivo (PMID 9417843). Isolated from many plants, free and combined. Alkyl esters of 4-hydroxybenzoic acid (see below) are used as food and cosmetic preservatives, mainly in their Na salt form, which makes them more water soluble. They are active at low concentrations and more pH-independent than the commonly used Benzoic acid DVN38-Z and 2,4-Hexadienoic acid GMZ10-P. The taste is more detectable than for those preservatives. Effectiveness increases with chain length of the alcohol, but for some microorganisms this reduces cell permeability and thus counteracts the increased efficiency. 4-Hydroxybenzoic acid is found in many foods, some of which are chicory, corn, rye, and black huckleberry. 4-hydroxybenzoic acid is a monohydroxybenzoic acid that is benzoic acid carrying a hydroxy substituent at C-4 of the benzene ring. It has a role as a plant metabolite and an algal metabolite. It is a conjugate acid of a 4-hydroxybenzoate. 4-Hydroxybenzoic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655).

Resveratrol

C14H12O3 (228.0786402)

Resveratrol is a stilbenol that is stilbene in which the phenyl groups are substituted at positions 3, 5, and 4 by hydroxy groups. It has a role as a phytoalexin, an antioxidant, a glioma-associated oncogene inhibitor and a geroprotector. It is a stilbenol, a polyphenol and a member of resorcinols. Resveratrol (3,5,4-trihydroxystilbene) is a polyphenolic phytoalexin. It is a stilbenoid, a derivate of stilbene, and is produced in plants with the help of the enzyme stilbene synthase. It exists as cis-(Z) and trans-(E) isomers. The trans- form can undergo isomerisation to the cis- form when heated or exposed to ultraviolet irradiation. In a 2004 issue of Science, Dr. Sinclair of Harvard University said resveratrol is not an easy molecule to protect from oxidation. It has been claimed that it is readily degraded by exposure to light, heat, and oxygen. However, studies find that Trans-resveratrol undergoes negligible oxidation in normal atmosphere at room temperature. Resveratrol is a plant polyphenol found in high concentrations in red grapes that has been proposed as a treatment for hyperlipidemia and to prevent fatty liver, diabetes, atherosclerosis and aging. Resveratrol use has not been associated with serum enzyme elevations or with clinically apparent liver injury. Resveratrol is a natural product found in Vitis rotundifolia, Vitis amurensis, and other organisms with data available. Resveratrol is a phytoalexin derived from grapes and other food products with antioxidant and potential chemopreventive activities. Resveratrol induces phase II drug-metabolizing enzymes (anti-initiation activity); mediates anti-inflammatory effects and inhibits cyclooxygenase and hydroperoxidase functions (anti-promotion activity); and induces promyelocytic leukemia cell differentiation (anti-progression activity), thereby exhibiting activities in three major steps of carcinogenesis. This agent may inhibit TNF-induced activation of NF-kappaB in a dose- and time-dependent manner. (NCI05) Resveratrol is a metabolite found in or produced by Saccharomyces cerevisiae. A stilbene and non-flavonoid polyphenol produced by various plants including grapes and blueberries. It has anti-oxidant, anti-inflammatory, cardioprotective, anti-mutagenic, and anti-carcinogenic properties. It also inhibits platelet aggregation and the activity of several DNA HELICASES in vitro. Resveratrol is a polyphenolic phytoalexin. It is also classified as a stilbenoid, a derivate of stilbene, and is produced in plants with the help of the enzyme stilbene synthase. The levels of resveratrol found in food vary greatly. Red wine contains between 0.2 and 5.8 mg/L depending on the grape variety, while white wine has much less. The reason for this difference is that red wine is fermented with grape skins, allowing the wine to absorb the resveratrol, whereas white wine is fermented after the skin has been removed. Resveratrol is also sold as a nutritional supplement. A number of beneficial health effects, such as anti-cancer, antiviral, neuroprotective, anti-aging, anti-inflammatory, and life-prolonging effects have been reported for resveratrol. The fact that resveratrol is found in the skin of red grapes and as a constituent of red wine may explain the "French paradox". This paradox is based on the observation that the incidence of coronary heart disease is relatively low in southern France despite high dietary intake of saturated fats. Resveratrol is thought to achieve these cardioprotective effects by a number of different routes: (1) inhibition of vascular cell adhesion molecule expression; (2) inhibition of vascular smooth muscle cell proliferation; (3) stimulation of endothelial nitric oxide synthase (eNOS) activity; (4) inhibition of platelet aggregation; and (5) inhibition of LDL peroxidation (PMID: 17875315, 14676260, 9678525). Resveratrol is a biomarker for the consumption of grapes and raisins. A stilbenol that is stilbene in which the phenyl groups are substituted at positions 3, 5, and 4 by hydroxy groups.

L-Phenylalanine

C9H11NO2 (165.0789746)

Phenylalanine (Phe), also known as L-phenylalanine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (‚ÄìNH2) and carboxyl (‚ÄìCOOH) functional groups, along with a side chain (R group) specific to each amino acid. L-phenylalanine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Phenylalanine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aromatic, non-polar amino acid. In humans, phenylalanine is an essential amino acid and the precursor of the amino acid tyrosine. Like tyrosine, phenylalanine is also a precursor for catecholamines including tyramine, dopamine, epinephrine, and norepinephrine. Catecholamines are neurotransmitters that act as adrenalin-like substances. Interestingly, several psychotropic drugs (mescaline, morphine, codeine, and papaverine) also have phenylalanine as a constituent. Phenylalanine is highly concentrated in the human brain and plasma. Normal metabolism of phenylalanine requires biopterin, iron, niacin, vitamin B6, copper, and vitamin C. An average adult ingests 5 g of phenylalanine per day and may optimally need up to 8 g daily. Phenylalanine is highly concentrated in a number of high protein foods, such as meat, cottage cheese, and wheat germ. An additional dietary source of phenylalanine is artificial sweeteners containing aspartame (a methyl ester of the aspartic acid/phenylalanine dipeptide). As a general rule, aspartame should be avoided by phenylketonurics and pregnant women. When present in sufficiently high levels, phenylalanine can act as a neurotoxin and a metabotoxin. A neurotoxin is a compound that disrupts or attacks neural cells and neural tissue. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of phenylalanine are associated with at least five inborn errors of metabolism, including Hartnup disorder, hyperphenylalaninemia due to guanosine triphosphate cyclohydrolase deficiency, phenylketonuria (PKU), tyrosinemia type 2 (or Richner-Hanhart syndrome), and tyrosinemia type III (TYRO3). Phenylketonurics have elevated serum plasma levels of phenylalanine up to 400 times normal. High plasma concentrations of phenylalanine influence the blood-brain barrier transport of large neutral amino acids. The high plasma phenylalanine concentrations increase phenylalanine entry into the brain and restrict the entry of other large neutral amino acids (PMID: 19191004). Phenylalanine has been found to interfere with different cerebral enzyme systems. Untreated phenylketonuria (PKU) can lead to intellectual disability, seizures, behavioural problems, and mental disorders. It may also result in a musty smell and lighter skin. Classic PKU dramatically affects myelination and white matter tracts in untreated infants; this may be one major cause of neurological disorders associated with phenylketonuria. Mild phenylketonuria can act as an unsuspected cause of hyperactivity, learning problems, and other developmental problems in children. It has been recently suggested that PKU may resemble amyloid diseases, such as Alzheimers disease and Parkinsons disease, due to the formation of toxic amyloid-like assemblies of phenylalanine (PMID: 22706200). Phenylalanine also has some potential benefits. Phenylalanine can act as an effective pain reliever. Its use in premenstrual syndrome and Parkinsons may enhance the effects of acupuncture and electric transcutaneous nerve stimulation (TENS). Phenylalanine and tyrosine, like L-DOPA, produce a catecholamine-like effect. Phenylalanine is better absorbed than tyrosine and may cause fewer headaches. Low phenylalanine diets have been prescribed for certain cancers with mixed results. For instance, some tumours use more phen... L-phenylalanine is an odorless white crystalline powder. Slightly bitter taste. pH (1\\\\\\% aqueous solution) 5.4 to 6. (NTP, 1992) L-phenylalanine is the L-enantiomer of phenylalanine. It has a role as a nutraceutical, a micronutrient, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite, a plant metabolite, an algal metabolite, a mouse metabolite, a human xenobiotic metabolite and an EC 3.1.3.1 (alkaline phosphatase) inhibitor. It is an erythrose 4-phosphate/phosphoenolpyruvate family amino acid, a proteinogenic amino acid, a phenylalanine and a L-alpha-amino acid. It is a conjugate base of a L-phenylalaninium. It is a conjugate acid of a L-phenylalaninate. It is an enantiomer of a D-phenylalanine. It is a tautomer of a L-phenylalanine zwitterion. Phenylalanine is an essential aromatic amino acid that is a precursor of melanin, [dopamine], [noradrenalin] (norepinephrine), and [thyroxine]. L-Phenylalanine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Phenylalanine is an essential aromatic amino acid in humans (provided by food), Phenylalanine plays a key role in the biosynthesis of other amino acids and is important in the structure and function of many proteins and enzymes. Phenylalanine is converted to tyrosine, used in the biosynthesis of dopamine and norepinephrine neurotransmitters. The L-form of Phenylalanine is incorporated into proteins, while the D-form acts as a painkiller. Absorption of ultraviolet radiation by Phenylalanine is used to quantify protein amounts. (NCI04) Phenylalanine is an essential amino acid and the precursor for the amino acid tyrosine. Like tyrosine, it is the precursor of catecholamines in the body (tyramine, dopamine, epinephrine and norepinephrine). The psychotropic drugs (mescaline, morphine, codeine, and papaverine) also have phenylalanine as a constituent.

Phenylalanine is highly concentrated in high protein foods, such as meat, cottage cheese and wheat germ. A new dietary source of phenylalanine is artificial sweeteners containing aspartame. Aspartame appears to be nutritious except in hot beverages; however, it should be avoided by phenylketonurics and pregnant women. Phenylketonurics, who have a genetic error of phenylalanine metabolism, have elevated serum plasma levels of phenylalanine up to 400 times normal. Mild phenylketonuria can be an unsuspected cause of hyperactivity, learning problems, and other developmental problems in children. Phenylalanine can be an effective pain reliever. Its use in premenstrual syndrome and Parkinsons may enhance the effects of acupuncture and electric transcutaneous nerve stimulation (TENS). Phenylalanine and tyrosine, like L-dopa, produce a catecholamine effect. Phenylalanine is better absorbed than tyrosine and may cause fewer headaches. Low phenylalanine diets have been prescribed for certain cancers with mixed results. Some tumors use more phenylalanine (particularly melatonin-producing tumors called melanoma). One strategy is to exclude this amino acid from the diet, i.e., a Phenylketonuria (PKU) diet (compliance is a difficult issue; it is hard to quantify and is under-researched). The other strategy is just to increase phenylalanines competing amino acids, i.e., tryptophan, valine, isoleucine and leucine, but not tyrosine. An essential aromatic amino acid that is a precursor of MELANIN; DOPAMINE; noradrenalin (NOREPINEPHRINE), and THYROXINE. See also: Plovamer (monomer of); Plovamer Acetate (monomer of) ... View More ... L-phenylalanine, also known as phe or f, belongs to phenylalanine and derivatives class of compounds. Those are compounds containing phenylalanine or a derivative thereof resulting from reaction of phenylalanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. L-phenylalanine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). L-phenylalanine can be found in watermelon, which makes L-phenylalanine a potential biomarker for the consumption of this food product. L-phenylalanine can be found primarily in most biofluids, including sweat, blood, urine, and cerebrospinal fluid (CSF), as well as throughout all human tissues. L-phenylalanine exists in all living species, ranging from bacteria to humans. In humans, L-phenylalanine is involved in a couple of metabolic pathways, which include phenylalanine and tyrosine metabolism and transcription/Translation. L-phenylalanine is also involved in few metabolic disorders, which include phenylketonuria, tyrosinemia type 2 (or richner-hanhart syndrome), and tyrosinemia type 3 (TYRO3). Moreover, L-phenylalanine is found to be associated with viral infection, dengue fever, hypothyroidism, and myocardial infarction. L-phenylalanine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Phenylalanine (Phe or F) is an α-amino acid with the formula C 9H 11NO 2. It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine. This essential amino acid is classified as neutral, and nonpolar because of the inert and hydrophobic nature of the benzyl side chain. The L-isomer is used to biochemically form proteins, coded for by DNA. The codons for L-phenylalanine are UUU and UUC. Phenylalanine is a precursor for tyrosine; the monoamine neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline); and the skin pigment melanin . Hepatic. L-phenylalanine that is not metabolized in the liver is distributed via the systemic circulation to the various tissues of the body, where it undergoes metabolic reactions similar to those that take place in the liver (DrugBank). If PKU is diagnosed early, an affected newborn can grow up with normal brain development, but only by managing and controlling phenylalanine levels through diet, or a combination of diet and medication. The diet requires severely restricting or eliminating foods high in phenylalanine, such as meat, chicken, fish, eggs, nuts, cheese, legumes, milk and other dairy products. Starchy foods, such as potatoes, bread, pasta, and corn, must be monitored. Optimal health ranges (or "target ranges") of serum phenylalanine are between 120 and 360 µmol/L, and aimed to be achieved during at least the first 10 years of life. Recently it has been found that a chiral isomer of L-phenylalanine (called D-phenylalanine) actually arrests the fibril formation by L-phenylalanine and gives rise to flakes. These flakes do not propagate further and prevent amyloid formation by L-phenylalanine. D-phenylalanine may qualify as a therapeutic molecule in phenylketonuria (A8161) (T3DB). L-Phenylalanine.

DL-Mannitol

C6H14O6 (182.0790344)

D-mannitol appears as odorless white crystalline powder or free-flowing granules. Sweet taste. (NTP, 1992) D-mannitol is the D-enantiomer of mannitol. It has a role as an osmotic diuretic, a sweetening agent, an antiglaucoma drug, a metabolite, an allergen, a hapten, a food bulking agent, a food anticaking agent, a food humectant, a food stabiliser, a food thickening agent, an Escherichia coli metabolite and a member of compatible osmolytes. Mannitol is an osmotic diuretic that is metabolically inert in humans and occurs naturally, as a sugar or sugar alcohol, in fruits and vegetables. Mannitol elevates blood plasma osmolality, resulting in enhanced flow of water from tissues, including the brain and cerebrospinal fluid, into interstitial fluid and plasma. As a result, cerebral edema, elevated intracranial pressure, and cerebrospinal fluid volume and pressure may be reduced. Mannitol may also be used for the promotion of diuresis before irreversible renal failure becomes established; the promotion of urinary excretion of toxic substances; as an Antiglaucoma agent; and as a renal function diagnostic aid. On October 30, 2020, mannitol was approved by the FDA as add-on maintenance therapy for the control of pulmonary symptoms associated with cystic fibrosis in adult patients and is currently marketed for this indication under the name BRONCHITOL® by Chiesi USA Inc. Mannitol is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Mannitol is an Osmotic Diuretic. The mechanism of action of mannitol is as an Osmotic Activity. The physiologic effect of mannitol is by means of Increased Diuresis. Mannitol is a natural product found in Pavetta indica, Scoparia dulcis, and other organisms with data available. Mannitol is a naturally occurring alcohol found in fruits and vegetables and used as an osmotic diuretic. Mannitol is freely filtered by the glomerulus and poorly reabsorbed from the renal tubule, thereby causing an increase in osmolarity of the glomerular filtrate. An increase in osmolarity limits tubular reabsorption of water and inhibits the renal tubular reabsorption of sodium, chloride, and other solutes, thereby promoting diuresis. In addition, mannitol elevates blood plasma osmolarity, resulting in enhanced flow of water from tissues into interstitial fluid and plasma. D-mannitol is a metabolite found in or produced by Saccharomyces cerevisiae. A diuretic and renal diagnostic aid related to sorbitol. It has little significant energy value as it is largely eliminated from the body before any metabolism can take place. It can be used to treat oliguria associated with kidney failure or other manifestations of inadequate renal function and has been used for determination of glomerular filtration rate. Mannitol is also commonly used as a research tool in cell biological studies, usually to control osmolarity. See also: Mannitol; sorbitol (component of); Mannitol; menthol (component of). Mannitol, or hexan-1,2,3,4,5,6-hexol (C6H8(OH)6), is an alcohol and a sugar (sugar alcohol), or a polyol, it is a stereoisomer of sorbitol and is similar to the C5 xylitol. The structure of mannitol is made of a straight chain of six carbon atoms, each of which is substituted with a hydroxyl group. Mannitol is one of the most abundant energy and carbon storage molecules in nature, it is produced by a wide range of organisms such as bacteria, fungi and plants (PMID: 19578847). In medicine, mannitol is used as a diuretic and renal diagnostic aid. Mannitol has little significant energy value as it is largely eliminated from the body before any metabolism can take place. It can be used to treat oliguria associated with kidney failure or other manifestations of inadequate renal function and has been used for determination of glomerular filtration rate. Mannitol is also commonly used as a research tool in cell biological studies, usually to control osmolarity. Mannitol has a tendency to lose a hydrogen ion in aqueous solutions, which causes the solution to become acidic. For this, it is not uncommon to add a weak base, such as sodium bicarbonate, to the solution to adjust its pH. Mannitol is a non-permeating molecule i.e., it cannot cross biological membranes. Mannitol is an osmotic diuretic agent and a weak renal vasodilator. Mannitol is found to be associated with cytochrome c oxidase deficiency and ribose-5-phosphate isomerase deficiency, which are inborn errors of metabolism. Mannitol is also a microbial metabolite found in Aspergillus, Candida, Clostridium, Gluconobacter, Lactobacillus, Lactococcus, Leuconostoc, Pseudomonas, Rhodobacteraceae, Saccharomyces, Streptococcus, Torulaspora and Zymomonas (PMID: 15240312; PMID: 29480337).

Cytidine

C9H13N3O5 (243.0855168)

Cytidine is a nucleoside that is composed of the base cytosine linked to the five-carbon sugar D-ribose. Cytidine is a pyrimidine that besides being incorporated into nucleic acids, can serve as a substrate for the salvage pathway of pyrimidine nucleotide synthesis. It is a precursor of cytidine triphosphate (CTP) needed in the phosphatidylcholine (PC) and phosphatidylethanolamine (PE) biosynthetic pathways. These variations probably reflect the species differences in cytidine deaminase, the enzyme that converts cytidine to uridine in the body. The transport of cytidine into the brains extracellular fluid, and then into neurons and glia, are essential prerequisites for cytidine to be utilized in the brain. An efficient mechanism mediating the brain uptake of circulating cytidine has not yet been demonstrated. The biosynthesis of PC, the most abundant phosphatide in the brain, via the Kennedy pathway requires phosphocholine and cytidine triphosphate (CTP), a cytidine nucleotide involved in the rate-limiting step. The enzyme that converts CTP to endogenous CDP-choline (CTP:phosphocholine cytidylyltransferase) is unsaturated at physiological brain CTP levels. APOBEC is a family of enzymes that has been discovered with the ability to deaminate cytidines on RNA or DNA. The human apolipoprotein B mRNA-editing enzyme, catalytic polypeptide-like 3G protein (APOBEC3G, or hA3G), provides cells with an intracellular antiretroviral activity that is associated with the hypermutation of viral DNA through cytidine deamination. Indeed, hA3G belongs to a family of vertebrate proteins that contains one or two copies of a signature sequence motif unique to cytidine deaminases (CTDAs) (PMID: 16769123, 15780864, 16720547).

It is an antioxidant, like many other phenolic heterocyclic compounds. Glycosylated forms include RUTIN and quercetrin. Quercetin is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Quercetin is a flavonoid found in many foods and herbs and is a regular component of a normal diet. Extracts of quercetin have been used to treat or prevent diverse conditions including cardiovascular disease, hypercholesterolemia, rheumatic diseases, infections and cancer but have not been shown to be effective in clinical trials for any medical condition. Quercetin as a nutritional supplement is well tolerated and has not been linked to serum enzyme elevations or to episodes of clinically apparent liver injury. Quercetin is a natural product found in Lotus ucrainicus, Visnea mocanera, and other organisms with data available. Quercetin is a polyphenolic flavonoid with potential chemopreventive activity. Quercetin, ubiquitous in plant food sources and a major bioflavonoid in the human diet, may produce antiproliferative effects resulting from the modulation of either EGFR or estrogen-receptor mediated signal transduction pathways. Although the mechanism of action of action is not fully known, the following effects have been described with this agent in vitro: decreased expression of mutant p53 protein and p21-ras oncogene, induction of cell cycle arrest at the G1 phase and inhibition of heat shock protein synthesis. This compound also demonstrates synergy and reversal of the multidrug resistance phenotype, when combined with chemotherapeutic drugs, in vitro. Quercetin also produces anti-inflammatory and anti-allergy effects mediated through the inhibition of the lipoxygenase and cyclooxygenase pathways, thereby preventing the production of pro-inflammatory mediators. Quercetin is a flavonoid widely distributed in many plants and fruits including red grapes, citrus fruit, tomato, broccoli and other leafy green vegetables, and a number of berries, including raspberries and cranberries. Quercetin itself (aglycone quercetin), as opposed to quercetin glycosides, is not a normal dietary component. Quercitin glycosides are converted to phenolic acids as they pass through the gastrointestinal tract. Quercetin has neither been confirmed scientifically as a specific therapeutic for any condition nor been approved by any regulatory agency. The U.S. Food and Drug Administration has not approved any health claims for quercetin. Nevertheless, the interest in dietary flavonoids has grown after the publication of several epidemiological studies showing an inverse correlation between dietary consumption of flavonols and flavones and reduced incidence and mortality from cardiovascular disease and cancer. In recent years, a large amount of experimental and some clinical data have accumulated regarding the effects of flavonoids on the endothelium under physiological and pathological conditions.

Succinic acid

C4H6O4 (118.0266076)

Succinic acid appears as white crystals or shiny white odorless crystalline powder. pH of 0.1 molar solution: 2.7. Very acid taste. (NTP, 1992) Succinic acid is an alpha,omega-dicarboxylic acid resulting from the formal oxidation of each of the terminal methyl groups of butane to the corresponding carboxy group. It is an intermediate metabolite in the citric acid cycle. It has a role as a nutraceutical, a radiation protective agent, an anti-ulcer drug, a micronutrient and a fundamental metabolite. It is an alpha,omega-dicarboxylic acid and a C4-dicarboxylic acid. It is a conjugate acid of a succinate(1-). A water-soluble, colorless crystal with an acid taste that is used as a chemical intermediate, in medicine, the manufacture of lacquers, and to make perfume esters. It is also used in foods as a sequestrant, buffer, and a neutralizing agent. (Hawleys Condensed Chemical Dictionary, 12th ed, p1099; McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed, p1851) Succinic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Succinic acid is a dicarboxylic acid. The anion, succinate, is a component of the citric acid cycle capable of donating electrons to the electron transfer chain. Succinic acid is created as a byproduct of the fermentation of sugar. It lends to fermented beverages such as wine and beer a common taste that is a combination of saltiness, bitterness and acidity. Succinate is commonly used as a chemical intermediate, in medicine, the manufacture of lacquers, and to make perfume esters. It is also used in foods as a sequestrant, buffer, and a neutralizing agent. Succinate plays a role in the citric acid cycle, an energy-yielding process and is metabolized by succinate dehydrogenase to fumarate. Succinate dehydrogenase (SDH) plays an important role in the mitochondria, being both part of the respiratory chain and the Krebs cycle. SDH with a covalently attached FAD prosthetic group, binds enzyme substrates (succinate and fumarate) and physiological regulators (oxaloacetate and ATP). Oxidizing succinate links SDH to the fast-cycling Krebs cycle portion where it participates in the breakdown of acetyl-CoA throughout the whole Krebs cycle. Succinate can readily be imported into the mitochondrial matrix by the n-butylmalonate- (or phenylsuccinate-) sensitive dicarboxylate carrier in exchange with inorganic phosphate or another organic acid, e.g. malate. (A3509) Mutations in the four genes encoding the subunits of succinate dehydrogenase are associated with a wide spectrum of clinical presentations (i.e.: Huntingtons disease. (A3510). Succinate also acts as an oncometabolite. Succinate inhibits 2-oxoglutarate-dependent histone and DNA demethylase enzymes, resulting in epigenetic silencing that affects neuroendocrine differentiation. A water-soluble, colorless crystal with an acid taste that is used as a chemical intermediate, in medicine, the manufacture of lacquers, and to make perfume esters. It is also used in foods as a sequestrant, buffer, and a neutralizing agent. (Hawleys Condensed Chemical Dictionary, 12th ed, p1099; McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed, p1851) Succinic acid (succinate) is a dicarboxylic acid. It is an important component of the citric acid or TCA cycle and is capable of donating electrons to the electron transfer chain. Succinate is found in all living organisms ranging from bacteria to plants to mammals. In eukaryotes, succinate is generated in the mitochondria via the tricarboxylic acid cycle (TCA). Succinate can readily be imported into the mitochondrial matrix by the n-butylmalonate- (or phenylsuccinate-) sensitive dicarboxylate carrier in exchange with inorganic phosphate or another organic acid, e. g. malate (PMID 16143825). Succinate can exit the mitochondrial matrix and function in the cytoplasm as well as the extracellular space. Succinate has multiple biological roles including roles as a metabolic intermediate and roles as a cell signalling molecule. Succinate can alter gene expression patterns, thereby modulating the epigenetic landscape or it can exhibit hormone-like signaling functions (PMID: 26971832). As such, succinate links cellular metabolism, especially ATP formation, to the regulation of cellular function. Succinate can be broken down or metabolized into fumarate by the enzyme succinate dehydrogenase (SDH), which is part of the electron transport chain involved in making ATP. Dysregulation of succinate synthesis, and therefore ATP synthesis, can happen in a number of genetic mitochondrial diseases, such as Leigh syndrome, and Melas syndrome. Succinate has been found to be associated with D-2-hydroxyglutaric aciduria, which is an inborn error of metabolism. Succinic acid has recently been identified as an oncometabolite or an endogenous, cancer causing metabolite. High levels of this organic acid can be found in tumors or biofluids surrounding tumors. Its oncogenic action appears to due to its ability to inhibit prolyl hydroxylase-containing enzymes. In many tumours, oxygen availability becomes limited (hypoxia) very quickly due to rapid cell proliferation and limited blood vessel growth. The major regulator of the response to hypoxia is the HIF transcription factor (HIF-alpha). Under normal oxygen levels, protein levels of HIF-alpha are very low due to constant degradation, mediated by a series of post-translational modification events catalyzed by the prolyl hydroxylase domain-containing enzymes PHD1, 2 and 3, (also known as EglN2, 1 and 3) that hydroxylate HIF-alpha and lead to its degradation. All three of the PHD enzymes are inhibited by succinate. In humans, urinary succinic acid is produced by Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Enterobacter, Acinetobacter, Proteus mirabilis, Citrobacter frundii, Enterococcus faecalis (PMID: 22292465). Succinic acid is also found in Actinobacillus, Anaerobiospirillum, Mannheimia, Corynebacterium and Basfia (PMID: 22292465; PMID: 18191255; PMID: 26360870). Succinic acid is widely distributed in higher plants and produced by microorganisms. It is found in cheeses and fresh meats. Succinic acid is a flavouring enhancer, pH control agent [DFC]. Succinic acid is also found in yellow wax bean, swamp cabbage, peanut, and abalone.

3,4-Dihydroxybenzeneacetic acid

C8H8O4 (168.0422568)

3,4-Dihydroxyphenylacetic acid (DOPAC) is a phenolic acid. DOPAC is a neuronal metabolite of dopamine (DA). DA undergoes monoamine oxidase-catalyzed oxidative deamination to 3,4-dihydroxyphenylacetaldehyde (DOPAL), which is metabolized primarily into DOPAC via aldehyde dehydrogenase (ALDH2). The biotransformation of DOPAL is critical as previous studies have demonstrated this DA-derived aldehyde to be a reactive electrophile and toxic to dopaminergic cells. Known inhibitors of mitochondrial ALDH2, such as 4-hydroxy-2-nonenal (4HNE) inhibit ALDH2-mediated oxidation of the endogenous neurotoxin DOPAL. 4HNE is one of the resulting products of oxidative stress, thus linking oxidative stress to the uncontrolled production of an endogenous neurotoxin relevant to Parkinsons disease. In early-onset Parkinson disease, there is markedly reduced activities of both monoamine oxidase (MAO) A and B. The amount of DOPAC, which is produced during dopamine oxidation by MAO, is greatly reduced as a result of increased parkin overexpression. Administration of methamphetamine to animals causes loss of DA terminals in the brain and significant decreases in dopamine and dihydroxyphenylacetic acid (DOPAC) in the striatum. Renal dopamine produced in the residual tubular units may be enhanced during a sodium challenge, thus behaving appropriately as a compensatory natriuretic hormone; however, the renal dopaminergic system in patients afflicted with renal parenchymal disorders should address parameters other than free urinary dopamine, namely the urinary excretion of L-DOPA and metabolites. DOPAC is one of the major phenolic acids formed during human microbial fermentation of tea, citrus, and soy flavonoid supplements. DOPAC exhibits a considerable antiproliferative effect in LNCaP prostate cancer and HCT116 colon cancer cells. The antiproliferative activity of DOPAC may be due to its catechol structure. A similar association of the catechol moiety in the B-ring with antiproliferative activity was demonstrated for flavanones (PMID:16956664, 16455660, 8561959, 11369822, 10443478, 16365058). DOPAC can be found in Gram-positive bacteria (PMID:24752840). 3,4-Dihydroxyphenylacetic acid (DOPAC) is a metabolite of the neurotransmitter dopamine. 3,4-Dihydroxyphenylacetic acid is found in many foods, some of which are alaska blueberry, cauliflower, ucuhuba, and fox grape. 3,4-Dihydroxybenzeneacetic acid is the main neuronal metabolite of dopamine.

Theobromine

C7H8N4O2 (180.0647228)

Theobromine is an odorless white crystalline powder. Bitter taste. pH (saturated solution in water): 5.5-7. (NTP, 1992) Theobromine, also known as xantheose, is the principal alkaloid of Theobroma cacao (cacao plant).[4] Theobromine is slightly water-soluble (330 mg/L) with a bitter taste.[5] In industry, theobromine is used as an additive and precursor to some cosmetics.[4] It is found in chocolate, as well as in a number of other foods, including tea (Camellia sinensis), some American hollies (yaupon and guayusa) and the kola nut. It is a white or colourless solid, but commercial samples can appear yellowish.[5] Theobromine is a dimethylxanthine having the two methyl groups located at positions 3 and 7. A purine alkaloid derived from the cacao plant, it is found in chocolate, as well as in a number of other foods, and is a vasodilator, diuretic and heart stimulator. It has a role as an adenosine receptor antagonist, a food component, a plant metabolite, a human blood serum metabolite, a mouse metabolite, a vasodilator agent and a bronchodilator agent. Theobromine (3,7-dimethylxanthine) is the principle alkaloid in Theobroma cacao (the cacao bean) and other plants. A xanthine alkaloid that is used as a bronchodilator and as a vasodilator.

It was formerly used as a diuretic and in the treatment of angina pectoris and hypertension. Theobromine is a bitter alkaloid of the methylxanthine family, which also includes the similar compounds theophylline and caffeine. Despite its name, the compound contains no bromine. Theobromine is derived from Theobroma, the genus of the cacao tree, which is composed of the Greek roots theo ("God") and broma ("food"), meaning "food of the gods". It is the primary alkaloid found in cocoa and chocolate, and is one of the causes for chocolates mood-elevating effects. The amount found in chocolate is small enough that chocolate can be safely consumed by humans in large quantities, but animals that metabolize theobromine more slowly, such as cats and dogs, can easily consume enough chocolate to cause chocolate poisoning. Theobromine is a stimulant frequently confused with caffeine. Theobromine has very different effects on the human body from caffeine; it is a mild, lasting stimulant with a mood improving effect, whereas caffeine has a strong, immediate effect and increases stress. In medicine, it is used as a diuretic, vasodilator, and myocardial stimulant. There is a possible association between prostate cancer and theobromine. Theobromine is a contributing factor in acid reflux because it relaxes the esophageal sphincter muscle, allowing stomach acid access to the esophagus.

Constituent of tea leaves (Camellia thea), cocoa Theobroma cacao, cola nut (Cola acuminata) and guarana (Paullinia cupana); flavouring ingredient with a bitter taste Biosynthesis Theobromine is a purine alkaloid derived from xanthosine, a nucleoside. Cleavage of the ribose and N-methylation yields 7-methylxanthosine. 7-Methylxanthosine in turn is the precursor to theobromine, which in turn is the precursor to caffeine.[24] Even without dietary intake, theobromine may occur in the body as it is a product of the human metabolism of caffeine, which is metabolised in the liver into 12\% theobromine, 4\% theophylline, and 84\% paraxanthine.[25] In the liver, theobromine is metabolized into xanthine and subsequently into methyluric acid.[26] Important enzymes include CYP1A2 and CYP2E1.[27] The elimination half life of theobromine is between 6 and 8 hours.[1][2] Unlike caffeine, which is highly water-soluble, theobromine is only slightly water-soluble and is more fat soluble, and thus peaks more slowly in the blood. While caffeine peaks after only 30 minutes, theobromine requires 2–3 hours to peak.[28] The primary mechanism of action for theobromine inside the body is inhibition of adenosine receptors.[5] Its effect as a phosphodiesterase inhibitor[29] is thought to be small.[5]

Galactitol

C6H14O6 (182.0790344)

Galactitol or dulcitol is a sugar alcohol that is a metabolic breakdown product of galactose. Galactose is derived from lactose in food (such as dairy products). When lactose is broken down by the enzyme lactase it produces glucose and galactose. Galactitol has a slightly sweet taste. It is produced from galactose in a reaction catalyzed by aldose reductase. When present in sufficiently high levels, galactitol can act as a metabotoxin, a neurotoxin, and a hepatotoxin. A neurotoxin is a compound that disrupts or attacks neural cells and neural tissue. A hepatotoxin as a compound that disrupts or attacks liver tissue or liver cells. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of galactitol are associated with at least two inborn errors of metabolism, including galactosemia and galactosemia type II. Galactosemia is a rare genetic metabolic disorder that affects an individuals ability to metabolize the sugar galactose properly. Excess lactose consumption in individuals with galactose intolerance or galactosemia activates aldose reductase to produce galactitol, thus depleting NADPH and leading to lowered glutathione reductase activity. As a result, hydrogen peroxide or other free radicals accumulate causing serious oxidative damage to various cells and tissues. In individuals with galactosemia, the enzymes needed for the further metabolism of galactose (galactose-1-phosphate uridyltransferase) are severely diminished or missing entirely, leading to toxic levels of galactose 1-phosphate, galactitol, and galactonate. High levels of galactitol in infants are specifically associated with hepatomegaly (an enlarged liver), cirrhosis, renal failure, cataracts, vomiting, seizure, hypoglycemia, lethargy, brain damage, and ovarian failure. Galactitol is an optically inactive hexitol having meso-configuration. It has a role as a metabolite, a human metabolite, an Escherichia coli metabolite and a mouse metabolite.

Phytosterols naturally occur in small amount in vegetable oils, especially soybean oil. One such phytosterol complex, isolated from vegetable oil, is cholestatin, composed of campesterol, stigmasterol, and brassicasterol, and is marketed as a dietary supplement. Sterols can reduce cholesterol in human subjects by up to 15\\\\\%. The mechanism behind phytosterols and the lowering of cholesterol occurs as follows : the incorporation of cholesterol into micelles in the gastrointestinal tract is inhibited, decreasing the overall amount of cholesterol absorbed. This may in turn help to control body total cholesterol levels, as well as modify HDL, LDL and TAG levels. Many margarines, butters, breakfast cereals and spreads are now enriched with phytosterols and marketed towards people with high cholesterol and a wish to lower it. -- Wikipedia.

It is a vitamin B5 and a pantothenic acid. It is a conjugate acid of a (R)-pantothenate. Pantothenic acid, also called pantothenate or vitamin B5 (a B vitamin), is a water-soluble vitamin discovered by Roger J. Williams in 1919. For many animals, pantothenic acid is an essential nutrient as it is required to synthesize coenzyme-A (CoA), as well as to synthesize and metabolize proteins, carbohydrates, and fats. Pantothenic acid is the amide between pantoic acid and β-alanine and commonly found as its alcohol analog, the provitamin panthenol, and as calcium pantothenate. Small quantities of pantothenic acid are found in nearly every food, with high amounts in whole-grain cereals, legumes, eggs, meat, royal jelly, avocado, and yogurt. Pantothenic acid is an ingredient in some hair and skin care products. Only the dextrorotatory (D) isomer of pantothenic acid possesses biological activity. while the levorotatory (L) form may antagonize the effects of the dextrorotatory isomer.

Biotin

C10H16N2O3S (244.0881586)

Biotin (also known as vitamin B7 or vitamin H) is one of the B vitamins.[1][2][3] It is involved in a wide range of metabolic processes, both in humans and in other organisms, primarily related to the utilization of fats, carbohydrates, and amino acids.[4] The name biotin, borrowed from the German Biotin, derives from the Ancient Greek word βίοτος (bíotos; 'life') and the suffix "-in" (a suffix used in chemistry usually to indicate 'forming').[5] Biotin appears as a white, needle-like crystalline solid.[6] Biotin is an organic heterobicyclic compound that consists of 2-oxohexahydro-1H-thieno[3,4-d]imidazole having a valeric acid substituent attached to the tetrahydrothiophene ring. The parent of the class of biotins. It has a role as a prosthetic group, a coenzyme, a nutraceutical, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a mouse metabolite, a cofactor and a fundamental metabolite. It is a member of biotins and a vitamin B7. It is a conjugate acid of a biotinate. A water-soluble, enzyme co-factor present in minute amounts in every living cell. It occurs mainly bound to proteins or polypeptides and is abundant in liver, kidney, pancreas, yeast, and milk. Biotin is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Biotin is a natural product found in Lysinibacillus sphaericus, Aspergillus nidulans, and other organisms with data available. Biotin is hexahydro-2-oxo-1H-thieno(3,4-d)imidazole-4-pentanoic acid.

The biotin content of cancerous tissue is higher than that of normal tissue. Biotin is an enzyme co-factor present in minute amounts in every living cell. Biotin is also known as vitamin H or B7 or coenzyme R. It occurs mainly bound to proteins or polypeptides and is abundant in liver, kidney, pancreas, yeast, and milk. Biotin has been recognized as an essential nutrient. Our biotin requirement is fulfilled in part through diet, through endogenous reutilization of biotin and perhaps through capture of biotin generated in the intestinal flora. The utilization of biotin for covalent attachment to carboxylases and its reutilization through the release of carboxylase biotin after proteolytic degradation constitutes the biotin cycle. Biotin deficiency is associated with neurological manifestations, skin rash, hair loss and metabolic disturbances that are thought to relate to the various carboxylase deficiencies (metabolic ketoacidosis with lactic acidosis). It has also been suggested that biotin deficiency is associated with protein malnutrition, and that marginal biotin deficiency in pregnant women may be teratogenic. Biotin acts as a carboxyl carrier in carboxylation reactions. There are four biotin-dependent carboxylases in mammals: those of propionyl-CoA (PCC), 3-methylcrotonyl-CoA (MCC), pyruvate (PC) and acetyl-CoA carboxylases (isoforms ACC-1 and ACC-2). All but ACC-2 are mitochondrial enzymes. The biotin moiety is covalently bound to the epsilon amino group of a Lysine residue in each of these carboxylases in a domain 60-80 amino acids long. The domain is structurally similar among carboxylases from bacteria to mammals.

Specifically, novel roles for biotin in cell signaling, gene expression, and chromatin structure have been identified in recent years. Human cells accumulate biotin by using both the sodium-dependent multivitamin transporter and monocarboxylate transporter 1. These transporters and other biotin-binding proteins partition biotin to compartments involved in biotin signaling: cytoplasm, mitochondria, and nuclei.

The activity of cell signals such as biotinyl-AMP, Sp1 and Sp3, nuclear factor (NF)-kappaB, and receptor tyrosine kinases depends on biotin supply. Consistent with a role for biotin and its catabolites in modulating these cell signals, greater than 2000 biotin-dependent genes have been identified in various human tissues. Many biotin-dependent gene products play roles in signal transduction and localize to the cell nucleus, consistent with a role for biotin in cell signalling. Posttranscriptional events related to ribosomal activity and protein folding may further contribute to the effects of biotin on gene expression. Finally, research has shown that biotinidase and holocarboxylase synthetase mediate covalent binding of biotin to histones (DNA-binding proteins), affecting chromatin structure; at least seven biotinylation sites have been identified in human histones. Biotinylation of histones appears to play a role in cell proliferation, gene silencing, and the cellular response to DNA repair. Roles for biotin in cell signalling and chromatin structure are consistent with the notion that biotin has a unique significance in cell biology (PMID: 15992684, 16011464).

These form 7-keto-8-aminopelargonic acid (KAPA). KAPA is transported from plant peroxisomes to mitochondria where it is converted to 7,8-diaminopelargonic acid (DAPA) with the help of the enzyme, BioA. The enzyme dethiobiotin synthetase catalyzes the formation of the ureido ring via a DAPA carbamate activated with ATP, creating dethiobiotin with the help of the enzyme, BioD, which is then converted into biotin which is catalyzed by BioB.[24] The last step is catalyzed by biotin synthase, a radical SAM enzyme. The sulfur is donated by an unusual [2Fe-2S] ferredoxin.[25] Depending on the species of bacteria, Biotin can be synthesized via multiple pathways.[24] Biotin (Vitamin B7) is a water-soluble B vitamin and serves as a coenzyme for five carboxylases in humans, involved in the synthesis of fatty acids, isoleucine, and valine, and in gluconeogenesis. Biotin is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids[1][2][3].

D-Xylitol

C5H12O5 (152.06847019999998)

Xylitol is a five-carbon sugar alcohol that is obtained through the diet. It is not endogenously produced by humans. Xylitol is used as a diabetic sweetener which is roughly as sweet as sucrose with 33\\\\\\% fewer calories. Xylitol is naturally found in many fruits (strawberries, plums, raspberries) and vegetables (e.g. cauliflower). Because of fruit and vegetable consumption the human body naturally processes 15 grams of xylitol per day. Xylitol can be produced industrially starting from primary matters rich in xylan which is hydrolyzed to obtain xylose. It is extracted from hemicelluloses present in the corn raids, the almond hulls or the barks of birch (or of the by-products of wood: shavings hard, paper pulp). Of all polyols, it is the one that has the sweetest flavor (it borders that of saccharose). It gives a strong refreshing impression, making xylitol an ingredient of choice for the sugarless chewing gum industry. In addition to his use in confectionery, it is used in the pharmaceutical industry for certain mouthwashes and toothpastes and in cosmetics (creams, soaps, etc.). Xylitol is produced starting from xylose, the isomaltose, by enzymatic transposition of the saccharose (sugar). Xylitol is not metabolized by cariogenic (cavity-causing) bacteria and gum chewing stimulates the flow of saliva; as a result, chewing xylitol gum may prevent dental caries. Chewing xylitol gum for 4 to 14 days reduces the amount of dental plaque. The reduction in the amount of plaque following xylitol gum chewing within 2 weeks may be a transient phenomenon. Chewing xylitol gum for 6 months reduced mutans streptococci levels in saliva and plaque in adults (PMID:17426399, 15964535). Studies have also shown xylitol chewing gum can help prevent acute otitis media (ear aches and infections) as the act of chewing and swallowing assists with the disposal of earwax and clearing the middle ear, while the presence of xylitol prevents the growth of bacteria in the eustachian tubes. Xylitol is well established as a life-threatening toxin to dogs. The number of reported cases of xylitol toxicosis in dogs has significantly increased since the first reports in 2002. Dogs that have ingested foods containing xylitol (greater than 100 milligrams of xylitol consumed per kilogram of bodyweight) have presented with low blood sugar (hypoglycemia), which can be life-threatening. Xylitol is found to be associated with ribose-5-phosphate isomerase deficiency, which is an inborn error of metabolism.

L-Isoleucine

C6H13NO2 (131.0946238)

Isoleucine (Ile) or L-isoleucine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-isolecuine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Isoleucine is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aliphatic amino acid. Isoleucine is an essential amino acid in humans, meaning the body cannot synthesize it and that it must be obtained from the diet. In plants and microorganisms, isoleucine is synthesized starting from pyruvate and alpha-ketobutyrate. Isoleucine is classified as a branched chain amino acid (BCAA). BCAAs include three amino acids: isoleucine, leucine and valine. They are alpha amino acids whose carbon structure is marked by a beta branch point. Despite their structural similarities, BCAAs have different metabolic routes, with valine going solely to carbohydrates (glucogenic), leucine solely to fats (ketogenic) and isoleucine being both a glucogenic and a ketogenic amino acid. Isoleucine is catabolized via with alpha-ketoglutarate where upon it is oxidized and split into propionyl-CoA and acetyl-CoA. Propionyl-CoA is converted into succinyl-CoA, a TCA cycle intermediate which can be converted into oxaloacetate for gluconeogenesis (hence glucogenic). The acetyl-CoA can be fed into the TCA cycle by condensing with oxaloacetate to form citrate or used in the synthesis of ketone bodies or fatty acids. The different metabolism of BCAAs accounts for different requirements for these essential amino acids in humans: 12 mg/kg, 14 mg/kg and 16 mg/kg of valine, leucine and isoleucine are required respectively. Furthermore, these amino acids have different deficiency symptoms. Valine deficiency is marked by neurological defects in the brain, while isoleucine deficiency is marked by muscle tremors. BCAAs are decreased in patients with liver disease, such as hepatitis, hepatic coma, cirrhosis, extrahepatic biliary atresia. An inability to break down isoleucine, along with other amino acids, is associated with maple syrup urine disease (MSUD) (PMID: 34125801). Isoleucine, like other BCAAs, is associated with insulin resistance. In particular, higher levels of isoleucine are observed in the blood of diabetic mice, rats, and humans (PMID 25287287). Mice fed an isoleucine deprivation diet for one day have improved insulin sensitivity, and feeding of an isoleucine deprivation diet for one week significantly decreases blood glucose levels (PMID: 24684822). L-isoleucine is the L-enantiomer of isoleucine. It has a role as a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a plant metabolite, a human metabolite, an algal metabolite and a mouse metabolite. It is an aspartate family amino acid, a proteinogenic amino acid, an isoleucine and a L-alpha-amino acid. It is a conjugate base of a L-isoleucinium. It is a conjugate acid of a L-isoleucinate. It is an enantiomer of a D-isoleucine. It is a tautomer of a L-isoleucine zwitterion. An essential branched-chain aliphatic amino acid found in many proteins. It is an isomer of leucine. It is important in hemoglobin synthesis and regulation of blood sugar and energy levels. L-Isoleucine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Isoleucine is one of nine essential amino acids in humans (present in dietary proteins), Isoleucine has diverse physiological functions, such as assisting wound healing, detoxification of nitrogenous wastes, stimulating immune function, and promoting secretion of several hormones. Necessary for hemoglobin formation and regulating blood sugar and energy levels, isoleucine is concentrated in muscle tissues in humans. Isoleucine is found especially in meats, fish, cheese, eggs, and most seeds and nuts. (NCI04) L-Isoleucine is one of the essential amino acids that cannot be made by the body and is known for its ability to help endurance and assist in the repair and rebuilding of muscle. This amino acid is important to body builders as it helps boost energy and helps the body recover from training. L-Isoleucine is also classified as a branched-chain amino acid (BCAA). It helps promote muscle recovery after exercise. Isoleucine is actually broken down for energy within the muscle tissue. It is important in hemoglobin synthesis and regulation of blood sugar and energy levels. An essential branched-chain aliphatic amino acid found in many proteins. It is an isomer of LEUCINE.

Putrescine

C4H12N2 (88.1000432)

Putrescine is a four-carbon alkane-alpha,omega-diamine. It is obtained by the breakdown of amino acids and is responsible for the foul odour of putrefying flesh. It has a role as a fundamental metabolite and an antioxidant. It is a conjugate base of a 1,4-butanediammonium. Putrescine is a toxic diamine formed by putrefaction from the decarboxylation of arginine and ornithine. Putrescine is a solid. This compound belongs to the polyamines. These are compounds containing more than one amine group. Known drug targets of putrescine include putrescine-binding periplasmic protein, ornithine decarboxylase, and S-adenosylmethionine decarboxylase proenzyme. Putrescine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). 1,4-Diaminobutane is a natural product found in Eupatorium cannabinum, Populus tremula, and other organisms with data available. Putrescine is a four carbon diamine produced during tissue decomposition by the decarboxylation of amino acids. Polyamines, including putrescine, may act as growth factors that promote cell division; however, putrescine is toxic at high doses. Putrescine is a uremic toxin. Uremic toxins can be subdivided into three major groups based upon their chemical and physical characteristics: 1) small, water-soluble, non-protein-bound compounds, such as urea; 2) small, lipid-soluble and/or protein-bound compounds, such as the phenols and 3) larger so-called middle-molecules, such as beta2-microglobulin. Chronic exposure of uremic toxins can lead to a number of conditions including renal damage, chronic kidney disease and cardiovascular disease.Putrescine is a polyamine. Putrescine is related to cadaverine (another polyamine). Both are produced by the breakdown of amino acids in living and dead organisms and both are toxic in large doses. Putrescine and cadaverine are largely responsible for the foul odor of putrefying flesh, but also contribute to the odor of such processes as bad breath and bacterial vaginosis. Putrescine is also found in semen. Putrescine attacks s-adenosyl methionine and converts it to spermidine. Spermidine in turn attacks another s-adenosyl methionine and converts it to spermine. Putrescine is synthesized in small quantities by healthy living cells by the action of ornithine decarboxylase. The polyamines, of which putrescine is one of the simplest, appear to be growth factors necessary for cell division. Putrescine apparently has specific role in skin physiology and neuroprotection. Pharmacological interventions have demonstrated convincingly that a steady supply of polyamines is a prerequisite for cell proliferation to occur. Genetic engineering of polyamine metabolism in transgenic rodents has shown that polyamines play a role in spermatogenesis, skin physiology, promotion of tumorigenesis and organ hypertrophy as well as neuronal protection. Transgenic activation of polyamine catabolism not only profoundly disturbs polyamine homeostasis in most tissues, but also creates a complex phenotype affecting skin, female fertility, fat depots, pancreatic integrity and regenerative growth. Transgenic expression of ornithine decarboxylase antizyme has suggested that this unique protein may act as a general tumor suppressor. Homozygous deficiency of the key biosynthetic enzymes of the polyamines, ornithine and S-adenosylmethionine decarboxylase is not compatible with murine embryogenesis. (A3286, A3287).

Xanthine

C5H4N4O2 (152.0334244)

Xanthine, also known as 2,6-dioxopurine, belongs to the class of organic compounds known as xanthines. These are purine derivatives with a ketone group conjugated at carbons 2 and 6 of the purine moiety. Xanthine is also classified as an oxopurine. An oxopurine in which the purine ring is substituted by oxo groups at positions 2 and 6 and N-9 is protonated. Xanthine exists in all living species, ranging from bacteria to plants to humans. In plants, several stimulants can be derived from xanthine, including caffeine, theophylline, and theobromine. Derivatives of xanthine (known collectively as xanthines) are a group of alkaloids commonly used for their effects as mild stimulants and as bronchodilators, notably in the treatment of asthma or influenza symptoms. Within humans, xanthine participates in a number of enzymatic reactions. In particular, xanthine can be biosynthesized from guanine; which is mediated by the enzyme guanine deaminase. In addition, xanthine and ribose 1-phosphate can be biosynthesized from xanthosine through the action of the enzyme purine nucleoside phosphorylase. In humans and other primates, xanthine can be converted to uric acid by the action of the xanthine oxidase enzyme. People with rare genetic disorders, specifically xanthinuria and Lesch–Nyhan syndrome, lack sufficient xanthine oxidase and cannot convert xanthine to uric acid. Individuals with xanthinuria have unusually high concentrations of xanthine in their blood and urine, which can lead to health problems such as renal failure and xanthine kidney stones. Individuals with Lesch-Nyhan syndrome have a deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HGPRT). The HGPRT deficiency causes a build-up of uric acid in all body fluids. This results in both high levels of uric acid in the blood and urine, associated with severe gout and kidney problems. Neurological signs include poor muscle control and moderate intellectual disability. 9H-xanthine is an oxopurine in which the purine ring is substituted by oxo groups at positions 2 and 6 and N-9 is protonated. It has a role as a Saccharomyces cerevisiae metabolite. It is a tautomer of a 7H-xanthine. A purine base found in most body tissues and fluids, certain plants, and some urinary calculi.

Kynurenic acid

C10H7NO3 (189.0425912)

Kynurenic acid is a quinolinemonocarboxylic acid that is quinoline-2-carboxylic acid substituted by a hydroxy group at C-4. It has a role as a G-protein-coupled receptor agonist, a NMDA receptor antagonist, a nicotinic antagonist, a neuroprotective agent, a human metabolite and a Saccharomyces cerevisiae metabolite. It is a monohydroxyquinoline and a quinolinemonocarboxylic acid. It is a conjugate acid of a kynurenate. Kynurenic Acid is under investigation in clinical trial NCT02340325 (FS2 Safety and Tolerability Study in Healthy Volunteers). Kynurenic acid is a natural product found in Ephedra foeminea, Ephedra intermedia, and other organisms with data available. Kynurenic acid is a uremic toxin. Uremic toxins can be subdivided into three major groups based upon their chemical and physical characteristics: 1) small, water-soluble, non-protein-bound compounds, such as urea; 2) small, lipid-soluble and/or protein-bound compounds, such as the phenols and 3) larger so-called middle-molecules, such as beta2-microglobulin. Chronic exposure of uremic toxins can lead to a number of conditions including renal damage, chronic kidney disease and cardiovascular disease. Kynurenic acid (KYNA) is a well-known endogenous antagonist of the glutamate ionotropic excitatory amino acid receptors N-methyl-D-aspartate (NMDA), alphaamino-3-hydroxy-5-methylisoxazole-4-propionic acid and kainate receptors and of the nicotine cholinergic subtype alpha 7 receptors. KYNA neuroprotective and anticonvulsive activities have been demonstrated in animal models of neurodegenerative diseases. Because of KYNAs neuromodulatory character, its involvement has been speculatively linked to the pathogenesis of a number of neurological conditions including those in the ageing process. Different patterns of abnormalities in various stages of KYNA metabolism in the CNS have been reported in Alzheimers disease, Parkinsons disease and Huntingtons disease. In HIV-1-infected patients and in patients with Lyme neuroborreliosis a marked rise of KYNA metabolism was seen. In the ageing process KYNA metabolism in the CNS of rats shows a characteristic pattern of changes throughout the life span. A marked increase of the KYNA content in the CNS occurs before the birth, followed by a dramatic decline on the day of birth. A low activity was seen during ontogenesis, and a slow and progressive enhancement occurs during maturation and ageing. This remarkable profile of KYNA metabolism alterations in the mammalian brain has been suggested to result from the development of the organisation of neuronal connections and synaptic plasticity, development of receptor recognition sites, maturation and ageing. There is significant evidence that KYNA can improve cognition and memory, but it has also been demonstrated that it interferes with working memory. Impairment of cognitive function in various neurodegenerative disorders is accompanied by profound reduction and/or elevation of KYNA metabolism. The view that enhancement of CNS KYNA levels could underlie cognitive decline is supported by the increased KYNA metabolism in Alzheimers disease, by the increased KYNA metabolism in downs syndrome and the enhancement of KYNA function during the early stage of Huntingtons disease. Kynurenic acid is the only endogenous N-methyl-D-aspartate (NMDA) receptor antagonist identified up to now, that mediates glutamatergic hypofunction. Schizophrenia is a disorder of dopaminergic neurotransmission, but modulation of the dopaminergic system by glutamatergic neurotransmission seems to play a key role. Despite the NMDA receptor antagonism, kynurenic acid also blocks, in lower doses, the nicotinergic acetycholine receptor, i.e., increased kynurenic acid levels can explain psychotic symptoms and cognitive deterioration. Kynurenic acid levels are described to be higher in the cerebrospinal fluid (CSF) and in critical central nervous system (CNS) regions of schizophrenics as compared to controls. (A3279, A3280)....

Pyridoxate

C8H9NO4 (183.0531554)

4-Pyridoxic acid is a member of the class of compounds known as methylpyridines. More specifically it is a 2-methylpyridine derivative substituted by a hydroxy group at C-3, a carboxy group at C-4, and a hydroxymethyl group at C-5. 4-Pyridoxic acid is the catabolic product of vitamin B6 (also known as pyridoxine, pyridoxal and pyradoxamine) and is excreted in the urine. Urinary levels of 4-pyridoxic acid are lower in females than in males and will be reduced even further in persons with a riboflavin deficiency. 4-Pyridoxic acid is formed by the action of aldehyde oxidase I (an endogenous enzyme) and by microbial enzymes (pyridoxal 4-dehydrogenase), an NAD-dependent aldehyde dehydrogenase. 4-pyridoxic acid can be further broken down by the gut microflora via the enzyme known as 4-pyridoxic acid dehydrogenase. This enzyme catalyzes the four-electron oxidation of 4-pyridoxic acid to 3-hydroxy-2-methylpyridine-4,5-dicarboxylate, using nicotinamide adenine dinucleotide (NAD) as a cofactor. 4-Pyridoxic acid is the catabolic product of vitamin B6 (also known as pyridoxine, pyridoxal and pyradoxamine) which is excreted in the urine.

[HMDB] Vitamin B6 is one of the B vitamins, and thus an essential nutrient.[1][2][3][4] The term refers to a group of six chemically similar compounds, i.e., "vitamers", which can be interconverted in biological systems. Its active form, pyridoxal 5′-phosphate, serves as a coenzyme in more than 140 enzyme reactions in amino acid, glucose, and lipid metabolism.[1][2][3] Plants synthesize pyridoxine as a means of protection from the UV-B radiation found in sunlight[5] and for the role it plays in the synthesis of chlorophyll.[6] Animals cannot synthesize any of the various forms of the vitamin, and hence must obtain it via diet, either of plants, or of other animals. There is some absorption of the vitamin produced by intestinal bacteria, but this is not sufficient to meet dietary needs. For adult humans, recommendations from various countries' food regulatory agencies are in the range of 1.0 to 2.0 milligrams (mg) per day. These same agencies also recognize ill effects from intakes that are too high, and so set safe upper limits, ranging from as low as 25 mg/day to as high as 100 mg/day depending on the country. Beef, pork, fowl and fish are generally good sources; dairy, eggs, mollusks and crustaceans also contain vitamin B6, but at lower levels. There is enough in a wide variety of plant foods so that a vegetarian or vegan diet does not put consumers at risk for deficiency.[7] Dietary deficiency is rare. Classic clinical symptoms include rash and inflammation around the mouth and eyes, plus neurological effects that include drowsiness and peripheral neuropathy affecting sensory and motor nerves in the hands and feet. In addition to dietary shortfall, deficiency can be the result of anti-vitamin drugs. There are also rare genetic defects that can trigger vitamin B6 deficiency-dependent epileptic seizures in infants. These are responsive to pyridoxal 5'-phosphate therapy.[8] 4-Pyridoxic acid is a catabolic product of vitamin B6 which is excreted in the urine.

Creatinine

C4H7N3O (113.0589092)

Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. Creatinine is transferred to the kidneys by blood plasma, whereupon it is eliminated from the body by glomerular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate by the body. Measuring serum creatinine is a simple test and it is the most commonly used indicator of renal function. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. The typical reference range for women is considered about 45-90 umol/l, for men 60-110 umol/l. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas. [HMDB].

Deoxycytidine

C9H13N3O4 (227.0906018)

Deoxycytidine, also known as dC, belongs to the class of organic compounds known as pyrimidine 2-deoxyribonucleosides. Pyrimidine 2-deoxyribonucleosides are compounds consisting of a pyrimidine linked to a ribose which lacks a hydroxyl group at position 2. Deoxycytidine is also classified as a deoxyribonucleoside, a component of deoxyribonucleic acid (DNA). Deoxycytidine is similar to the ribonucleoside cytidine, but with one hydroxyl group removed from the 2 position. Deoxycytidine exists in all living species, ranging from bacteria to plants to humans. Degradation of DNA through apoptosis or cell death produces deoxycytidine. Within humans, deoxycytidine participates in a number of enzymatic reactions. In particular, deoxycytidine can be biosynthesized from dCMP through the action of the enzyme cytosolic purine 5-nucleotidase. In addition, deoxycytidine can be converted into dCMP; which is mediated by the enzyme uridine-cytidine kinase-like 1. Deoxycytidine can be phosphorylated at the C-5 position by the enzyme deoxycytidine kinase to produce deoxycytidine monophosphate (dCMP), and to a lesser extent, deoxycytidine diphosphate (dCDP), and deoxycytidine triphosphate (dCTP). Deoxycytidine can also be phosphorylated by thymidine kinase 2 (TK2). Deoxycytidine can potentially be used for the treatment of the metabolic disorder known as thymidine kinase 2 deficiency (TK2 deficiency). TK2 deficiency has three disease subtypes: i) infantile-onset myopathy with rapid progression to early death ii) childhood-onset myopathy, which resembles spinal muscular atrophy (SMA) type III, begins between ages 1 and 12 years with progression to loss of ambulation within few years and iii) late-onset myopathy starting at age 12 year or later with moderate to severe myopathy manifesting as either isolated chronic progressive external ophthalmoplegia (CPEO) or a generalized myopathy with CPEO plus facial and limb weakness, gradual progression, and, in some cases, respiratory failure and loss of ability to walk in adulthood (PMID: 28318037). In mouse models of TK2, dC was shown to delay disease onset, prolong life span and restore mtDNA copy number as well as respiratory chain enzyme activities (PMID: 28318037). One of the principal nucleosides of DNA composed of cytosine and deoxyribose. A nucleoside consists of only a pentose sugar linked to a purine or pyrimidine base, without a phosphate group. When N1 is linked to the C1 of deoxyribose, deoxynucleosides and nucleotides are formed from cytosine and deoxyribose; deoxycytidine monophosphate (dCMP), deoxycytidine diphosphate (dCDP), deoxycytidine triphosphate (dCTP). CTP is the source of the cytidine in RNA (ribonucleic acid) and deoxycytidine triphosphate (dCTP) is the source of the deoxycytidine in DNA (deoxyribonucleic acid). [HMDB]. Deoxycytidine is found in many foods, some of which are japanese pumpkin, turmeric, prairie turnip, and kai-lan.

2'-Deoxycytidine-5'-monophosphoric acid

C9H14N3O7P (307.0569344)

Deoxycytidine monophosphate (dCMP), also known as deoxycytidylic acid or deoxycytidylate in its conjugate acid and conjugate base forms, respectively, is a deoxynucleotide, and one of the four monomers that make up DNA. In a DNA double helix, it will base pair with deoxyguanosine monophosphate. dCMP belongs to the class of organic compounds known as pyrimidine 2-deoxyribonucleoside monophosphates. These are pyrimidine nucleotides with a monophosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. Deficiency of the enzyme deoxycytidine kinase (EC2.7.1.74) is associated with resistance to antiviral and anticancer chemotherapeutic agents, whereas increased enzyme activity is associated with increased activation of these compounds to cytotoxic nucleoside triphosphate derivatives. dCMP exists in all living species, ranging from bacteria to humans. Within humans, dCMP participates in a number of enzymatic reactions. In particular, dCMP can be converted to dCDP by the enzyme UMP-CMP kinase 2.

Deoxyadenosine

C10H13N5O3 (251.10183480000003)

Deoxyadenosine is a derivative of the nucleoside adenosine. It is composed of adenine attached to a deoxyribose moiety via a N9-glycosidic bond. Deoxyribose differs from ribose by the absence of oxygen in the 3 position of its ribose ring. Deoxyadenosine is a critical component of DNA. When present in sufficiently high levels, deoxyadensoine can act as an immunotoxin and a metabotoxin. An immunotoxin disrupts, limits the function, or destroys immune cells. A metabotoxin is an endogenous metabolite that causes adverse health effects at chronically high levels. Chronically high levels of deoxyadenosine are associated with adenosine deaminase (ADA) deficiency, an inborn error of metabolism. ADA deficiency damages the immune system and causes severe combined immunodeficiency (SCID). People with SCID lack virtually all immune protection from bacteria, viruses, and fungi. They are prone to repeated and persistent infections that can be very serious or life-threatening. These infections are often caused by "opportunistic" organisms that ordinarily do not cause illness in people with a normal immune system. The main symptoms of ADA deficiency are pneumonia, chronic diarrhea, and widespread skin rashes. The mechanism by which dATP functions as an immunotoxin is as follows: because deoxyadenosine is a precursor to dATP, a buildup of dATP in cells inhibits ribonucleotide reductase and prevents DNA synthesis, so cells are unable to divide. Since developing T cells and B cells are some of the most mitotically active cells, they are unable to divide and propagate to respond to immune challenges. High levels of deoxyadenosine also lead to an increase in S-adenosylhomocysteine, which is toxic to immature lymphocytes. Deoxyadenosine is a derivative of nucleoside adenosine. It is comprised of adenine attached to a deoxyribose moiety via a N9-glycosidic bond. Deoxyribose differs from ribose by the absence of oxygen in the 3 position of its ribose ring.

3-Indoleacetonitrile

C10H8N2 (156.0687448)

3-Indoleacetonitrile is a phytoalexin. Phytoalexins are antibiotics produced by plants that are under attack. Phytoalexins tend to fall into several classes including terpenoids, glycosteroids, and alkaloids; however, researchers often find it convenient to extend the definition to include all phytochemicals that are part of the plants defensive arsenal. Phytoalexins produced in plants act as toxins to the attacking organism. They may puncture the cell wall, delay maturation, disrupt metabolism, or prevent the reproduction of the pathogen in question. However, phytoalexins are often targeted to specific predators; a plant that has anti-insect phytoalexins may not have the ability to repel a fungal attack. 3-Indoleacetonitrile is common in cruciferous vegetables such as cabbage, cauliflower, broccoli, and Brussels sprouts. Dietary indoles in cruciferous vegetables induce cytochrome P450 enzymes and have prevented tumours in various animal models. Consumption of Brassica vegetables is associated with a reduced risk of cancer of the alimentary tract in animal models and human populations (PMID:15612779, 15884814, 2342128, 3014947, 3880668, 6334634, 6419397, 6426808, 6584878, 6725517, 6838646, 7123561).

1-Methylhistidine

C7H11N3O2 (169.0851226)

1-Methylhistidine, also known as 1-MHis or 1MH, belongs to the class of organic compounds known as histidine and derivatives. 1MH is also classified as a methylamino acid. Methylamino acids are primarily proteogenic amino acids (found in proteins) which have been methylated (in situ) on their side chains by various methyltransferase enzymes. Histidine can be methylated at either the N1 or N3 position of its imidazole ring, yielding the isomers 1-methylhistidine (1MH; also referred to as pi-methylhistidine) or 3-methylhistidine (3MH; tau-methylhistidine), respectively. There is considerable confusion with regard to the nomenclature of the methylated nitrogen atoms on the imidazole ring of histidine and other histidine-containing peptides such as anserine. In particular, older literature (mostly prior to the year 2000) designated anserine (Npi methylated) as beta-alanyl-N1-methyl-histidine, whereas according to standard IUPAC nomenclature, anserine is correctly named as beta-alanyl-N3-methyl-histidine. As a result, many papers published prior to the year 2000 incorrectly identified 1MH as a specific marker for dietary consumption or various pathophysiological effects when they really were referring to 3MH (PMID: 24137022). Recent discoveries have shown that 1MH is produced in essentially all mammals (and other vertebrates) via the enzyme known as METTL9 (PMID: 33563959). METTL9 is a broad-specificity methyltransferase that mediates the formation of the majority of 1MH present in mammalian proteomes. METTL9-catalyzed methylation requires a His-x-His (HxH) motif, where "x" is a small amino acid. This HxH motif is found in a number of abundant mammalian proteins such as ARMC6, S100A9, and NDUFB3 (PMID: 33563959). Because of its abundance in many muscle-related proteins, 1MH has been found to be a good biomarker for the consumption of meat (PMID: 21527577). Dietary studies have shown that poultry consumption (p-trend = 0.0006) and chicken consumption (p-trend = 0.0003) are associated with increased levels of 1MH in human plasma (PMID: 30018457). The consumption of fish, especially salmon and cod, has also been shown to increase the levels of 1MH in serum and urine (PMID: 31401679). As a general rule, urinary 1MH is associated with white meat intake (p< 0.001), whereas urinary 3MH is associated with red meat intake (p< 0.001) (PMID: 34091671). 1-Methyl-L-histidine is an objective indicator of meat ingestion and exogenous 3-methylhistidine (3MH) intake. 1-Methyl-L-histidine is an objective indicator of meat ingestion and exogenous 3-methylhistidine (3MH) intake. 3-Methyl-L-histidine is a biomarker for meat consumption, especially chicken. It is also a biomarker for the consumption of soy products.

4-Aminobenzoic acid

C7H7NO2 (137.0476762)

p-Aminobenzoic acid, also known as 4-aminobenzoic acid or PABA, is an organic compound with molecular formula C7H7NO2. PABA is a white crystalline substance that is only slightly soluble in water. It consists of a benzene ring substituted with an amino group and a carboxylic acid. PABA is an essential nutrient for some bacteria and is sometimes called vitamin Bx. However, PABA is not essential for humans and it varies in its activity from other B vitamins. PABA is sometimes marketed as an essential nutrient under the premise that it can stimulate intestinal bacteria. Certain bacteria in the human intestinal tract such as E. coli generate PABA from chorismate. Humans lack the enzymes to convert PABA into folate, and therefore require folate from dietary sources such as green leafy vegetables. Although some intestinal bacteria can synthesize folate from PABA and some E. coli can synthesize folate this requires six enzymatic activities in folate synthesis which are not all done in the same bacteria. PABA used to be a common sunscreen agent until it was found to also be a sensitizer. The potassium salt of PABA is used therapeutically in fibrotic skin disorders. PABA can also be found in Acetobacter (DOI: 10.3181/00379727-52-14147).

5-Aminopentanoic acid

C5H11NO2 (117.0789746)

5-Aminopentanoic acid (or 5-aminovalerate) is a lysine degradation product. It can be produced both endogenously or through bacterial catabolism of lysine. 5-aminovalerate is formed via the following multi-step reaction: L-lysine leads to cadverine leads to L-piperideine leads 5-aminovalerate (PMID:405455). In other words it is a metabolite of cadaverine which is formed via the intermediate, 1-piperideine (PMID:6436440). Cadaverine is a foul-smelling diamine compound produced by protein hydrolysis during putrefaction of animal tissue. High levels of 5-aminovalerate in biofluids may indicate bacterial overgrowth or endogenous tissue necrosis. In most cases endogenous 5-aminovalerate is thought to be primarily a microbial metabolite produced by the gut or oral microflora, although it can be produced endogenously. 5-aminovalerate is a normal metabolite present in human saliva, with a tendency to elevated concentration in patients with chronic periodontitis. Bacterial contamination and decomposition of salivary proteins is primarily responsible for elevated salivary levels (PMID 3481959). Beyond being a general waste product, 5-aminovalerate is also believed to act as a methylene homologue of gamma-aminobutyric acid (GABA) and functions as a weak GABA agonist (PMID:4031870). It is also known as an antifibrinolytic amino acid analog and so it functions as a weak inhibitor of the blood clotting pathway (PMID:6703712). 5- aminovalerate is an in vivo substrate of 4-aminobutyrate:2-oxoglutarate aminotransferase (PMID:4031870).

Nandrolone

C18H26O2 (274.1932696)

Nandrolone is a C18 steroid with androgenic and anabolic properties. It is generally prepared from alkyl ethers of estradiol to resemble testosterone, but it has one less carbon atom at the 19 position (Pubchem). Nandrolone is an anabolic steroid occurring naturally in the human body, albeit in small quantities. Nandrolone is most commonly sold commercially as its decanoate ester (Deca-Durabolin) and less commonly as a phenylpropionate ester (Durabolin). Nandrolone use is indirectly detectable in urine tests by testing for the presence of 19-norandrosterone, a metabolism product of this molecule. The International Olympic Committee has set a limit of 2 ng per ml of urine as the upper limit, beyond which an athlete is suspected of doping (Wikipedia).

Oxoglutaric acid

C5H6O5 (146.0215226)

Oxoglutaric acid, also known as alpha-ketoglutarate, alpha-ketoglutaric acid, AKG, or 2-oxoglutaric acid, is classified as a gamma-keto acid or a gamma-keto acid derivative. gamma-Keto acids are organic compounds containing an aldehyde substituted with a keto group on the C4 carbon atom. alpha-Ketoglutarate is considered to be soluble (in water) and acidic. alpha-Ketoglutarate is a key molecule in the TCA cycle, playing a fundamental role in determining the overall rate of this important metabolic process (PMID: 26759695). In the TCA cycle, AKG is decarboxylated to succinyl-CoA and carbon dioxide by AKG dehydrogenase, which functions as a key control point of the TCA cycle. Additionally, AKG can be generated from isocitrate by oxidative decarboxylation catalyzed by the enzyme known as isocitrate dehydrogenase (IDH). In addition to these routes of production, AKG can be produced from glutamate by oxidative deamination via glutamate dehydrogenase, and as a product of pyridoxal phosphate-dependent transamination reactions (mediated by branched-chain amino acid transaminases) in which glutamate is a common amino donor. AKG is a nitrogen scavenger and a source of glutamate and glutamine that stimulates protein synthesis and inhibits protein degradation in muscles. In particular, AKG can decrease protein catabolism and increase protein synthesis to enhance bone tissue formation in skeletal muscles (PMID: 26759695). Interestingly, enteric feeding of AKG supplements can significantly increase circulating plasma levels of hormones such as insulin, growth hormone, and insulin-like growth factor-1 (PMID: 26759695). It has recently been shown that AKG can extend the lifespan of adult C. elegans by inhibiting ATP synthase and TOR (PMID: 24828042). In combination with molecular oxygen, alpha-ketoglutarate is required for the hydroxylation of proline to hydroxyproline in the production of type I collagen. A recent study has shown that alpha-ketoglutarate promotes TH1 differentiation along with the depletion of glutamine thereby favouring Treg (regulatory T-cell) differentiation (PMID: 26420908). alpha-Ketoglutarate has been found to be associated with fumarase deficiency, 2-ketoglutarate dehydrogenase complex deficiency, and D-2-hydroxyglutaric aciduria, which are all inborn errors of metabolism (PMID: 8338207). Oxoglutaric acid has been found to be a metabolite produced by Corynebacterium and yeast (PMID: 27872963) (YMDB).

N-Acetylserotonin

C12H14N2O2 (218.1055224)

N-Acetylserotonin (NAS), also known as normelatonin, is a naturally occurring chemical precursor and intermediate in the endogenous production of melatonin from serotonin. It also has biological activity in its own right, including acting as a melatonin receptor agonist, an agonist of the TrkB, and having antioxidant effects. N-Acetylserotonin is an intermediate in the metabolic pathway of melatonin and indoleamine in the pineal gland of mammalians. Serotonin-N-acetyltransferase (SNAT), which regulates the rate of melatonin biosynthesis in the pineal gland, catalyzes the acetylation of 5HT to N-acetylserotonin (NAS). A methyl group from S-adenosylmethionine is transferred to NAS by hydroxyindole-O-methyltransferase (HIOMT), and finally NAS is converted to 5-methoxy-N-acetyltryptamine, or melatonin. In most mammalian species the content of NAS (and melatonin) in the pineal gland shows clear circadian changes with the highest level occurring during the dark period. This elevation of the contents of NAS (and melatonin) in the dark period is due to the increase of SNAT activity and the elevation of SNAT gene expression. Experimental studies show that N-acetylserotonin possess free radical scavenging activity. Acute administration of irreversible and reversible selective MAO-A inhibitors and high doses (or chronic administration of low doses) of relatively selective MAO-B inhibitors (but not of highly selective MAO-B inhibitors) suppressed MAO-A activity and stimulated N-acetylation of pineal serotonin into N-acetylserotonin, the immediate precursor of melatonin. N-acetylserotonin increase after MAO-A inhibitors might mediate their antidepressive and antihypertensive effects. N-Acetylserotonin is the product of the O-demethylation of melatonin mediated by cytochrome P-450 isoforms: Cytochrome p450, subfamily IIc, polypeptide 19 (CYP2C19, a clinically important enzyme that metabolizes a wide variety of drugs), with a minor contribution from Cytochrome p450, subfamily I, polypeptide (2CYP1A2, involved in O-deethylation of phenacetin). (PMID 15616152, 11103901, 10721079, 10591054). N-Acetylserotonin acts as a potent antioxidant, NAS effectiveness as an anti-oxidant has been found to be different depending on the experimental model used, it has been described as being between 5 and 20 times more effect than melatonin at protecting against oxidant damage. NAS has been shown to protect against lipid peroxidation in microsomes and mitochondria. NAS has also been reported to lower resting levels of ROS in peripheral blood lymphocytes and to exhibit anti-oxidant effects against t-butylated hydroperoxide- and diamide-induced ROS. N-acetyl serotonin, also known as N-acetyl-5-hydroxytryptamine or N-(2-(5-hydroxy-1h-indol-3-yl)ethyl)acetamide, is a member of the class of compounds known as hydroxyindoles. Hydroxyindoles are organic compounds containing an indole moiety that carries a hydroxyl group. N-acetyl serotonin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). N-acetyl serotonin can be found in a number of food items such as tronchuda cabbage, winter savory, rambutan, and poppy, which makes N-acetyl serotonin a potential biomarker for the consumption of these food products. N-acetyl serotonin can be found primarily in blood and urine, as well as in human kidney and liver tissues. In humans, N-acetyl serotonin is involved in the tryptophan metabolism. Moreover, N-acetyl serotonin is found to be associated with schizophrenia. N-Acetyl-5-hydroxytryptamine is a Melatonin precursor, and that it can potently activate TrkB receptor.

N-Acetyl-L-phenylalanine

C11H13NO3 (207.0895388)

N-Acetyl-L-phenylalanine or N-Acetylphenylalanine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetyl-L-phenylalanine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetyl-L-phenylalanine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-phenylalanine. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\\% of all human proteins and 68\\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetylphenylalanine can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free phenylalanine can also occur. In particular, N-Acetyl-L-phenylalanine can be biosynthesized from L-phenylalanine and acetyl-CoA by the enzyme phenylalanine N-acetyltransferase (EC 2.3.1.53). N-Acetyl-L-phenylalanine is a potential uremic toxin and is considered as a hazardous amphipathic metabolite of phenylalanine (PMID: 4038506). Many N-acetylamino acids, including N-acetylphenylalanine, are classified as uremic toxins (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). N-Acetyl-L-phenylalanine appears in large amount in urine of patients with phenylketonuria (PKU), which is a human genetic disorder due to the lack of phenylalanine hydroxylase, the enzyme necessary to metabolize phenylalanine to tyrosine (PMID: 3473611). N-Acetyl-L-phenylalanine is a product of enzyme phenylalanine N-acetyltransferase [EC 2.3.1.53] which is found in the phenylalanine metabolism pathway. N-Acetyl-L-phenylalanine is produced for medical, feed, and nutritional applications such as in the preparation of aspartame. Afalanine (N-Acetyl-DL-phenylalanine) is also approved for use as an antidepressant. Acetylphenylalanine is a hazardous amphipathic metabolite of phenylalanine. It appears in large amount in urine of patients with phenylketonuria which is a human genetic disorder due to the lack of phenylalanine hydroxylase, the enzyme necessary to metabolize phenylalanine to tyrosine.

Argininosuccinic acid disodium

C10H18N4O6 (290.12262880000003)

Arginosuccinic acid is a basic amino acid. Some cells synthesize it from citrulline, aspartic acid and use it as a precursor for arginine in the urea cycle or Citrulline-NO cycle. The enzyme that catalyzes the reaction is argininosuccinate synthetase. Argininosuccinic acid is a precursor to fumarate in the citric acid cycle via argininosuccinate lyase. Defects in the argininosuccinate lyase enzyme can lead to argininosuccinate lyase deficiency, which is an inborn error of metabolism. Argininosuccinate (ASA) lyase deficiency results in defective cleavage of ASA. This leads to an accumulation of ASA in cells and an excessive excretion of ASA in urine (argininosuccinic aciduria). In virtually all respects, this disorder shares the characteristics of other urea cycle defects. The most important characteristic of ASA lyase deficiency is its propensity to cause hyperammonemia in affected individuals. ASA in affected individuals is excreted by the kidney at a rate practically equivalent to the glomerular filtration rate (GFR). Whether ASA itself causes a degree of toxicity due to hepatocellular accumulation is unknown; such an effect could help explain hyperammonemia development in affected individuals. Regardless, the name of the disease is derived from the rapid clearance of ASA in urine, although elevated levels of ASA can be found in plasma. ASA lyase deficiency is associated with high mortality and morbidity rates. Symptoms of ASA lyase deficiency include anorexia, irritability rapid breathing, lethargy and vomiting. Extreme symptoms include coma and cerebral edema. Arginosuccinic acid is a basic amino acid.

Asparagine

C4H8N2O3 (132.05348980000002)

Asparagine (Asn) or L-asparagine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-asparagine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Asparagine is found in all organisms ranging from bacteria to plants to animals. In humans, asparagine is not an essential amino acid, which means that it can be synthesized from central metabolic pathway intermediates in humans and is not required in the diet. The precursor to asparagine is oxaloacetate. Oxaloacetate is converted to aspartate using a transaminase enzyme. This enzyme transfers the amino group from glutamate to oxaloacetate producing alpha-ketoglutarate and aspartate. The enzyme asparagine synthetase produces asparagine, AMP, glutamate, and pyrophosphate from aspartate, glutamine, and ATP. In the asparagine synthetase reaction, ATP is used to activate aspartate, forming beta-aspartyl-AMP. Glutamine donates an ammonium group which reacts with beta-aspartyl-AMP to form asparagine and free AMP. Since the asparagine side chain can make efficient hydrogen bond interactions with the peptide backbone, asparagines are often found near the beginning and end of alpha-helices, and in turn motifs in beta sheets. Its role can be thought as "capping" the hydrogen bond interactions which would otherwise need to be satisfied by the polypeptide backbone. Asparagine also provides key sites for N-linked glycosylation, a modification of the protein chain that is characterized by the addition of carbohydrate chains. A reaction between asparagine and reducing sugars or reactive carbonyls produces acrylamide (acrylic amide) in food when heated to sufficient temperature (i.e. baking). These occur primarily in baked goods such as French fries, potato chips, and roasted coffee. Asparagine was first isolated in 1806 from asparagus juice --hence its name. Asparagine was the first amino acid to be isolated. The smell observed in the urine of some individuals after the consumption of asparagus is attributed to a byproduct of the metabolic breakdown of asparagine, asparagine-amino-succinic-acid monoamide. However, some scientists disagree and implicate other substances in the smell, especially methanethiol. [Spectral] L-Asparagine (exact mass = 132.05349) and L-Aspartate (exact mass = 133.03751) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX.

Beta-pseudouridine, also known as p or 5-(b-D-ribofuranosyl)uracil, is a member of the class of compounds known as nucleoside and nucleotide analogues. Nucleoside and nucleotide analogues are analogues of nucleosides and nucleotides. These include phosphonated nucleosides, C-glycosylated nucleoside bases, analogues where the sugar unit is a pyranose, and carbocyclic nucleosides, among others. Beta-pseudouridine is soluble (in water) and a very weakly acidic compound (based on its pKa). Beta-pseudouridine can be found in a number of food items such as eggplant, wax gourd, asparagus, and garden cress, which makes beta-pseudouridine a potential biomarker for the consumption of these food products.

These are analogues of nucleosides and nucleotides, such as phosphonated nucleosides, C-glycosylated nucleoside bases, analogues where the sugar unit is a pyranose, and carbocyclic nucleosides. Pseudouridine specifically has its uracil attached via a carbon-carbon instead of a nitrogen-carbon glycosidic bond to the ribofuranose. It is the most prevalent of the over one hundred different modified nucleosides found in RNA (PMID: 17113994). Pseudouridine is a solid that is soluble in water. Pseudouridine exists in all living species, ranging from bacteria to humans, and is in all classes of RNA except mRNA. It is formed by enzymes called pseudouridine synthases, which post-transcriptionally isomerize specific uridine residues in RNA. Pseudouridine. CAS Common Chemistry.

cis,cis-Muconic acid

C6H6O4 (142.0266076)

cis-cis-Muconic acid is a presumptive metabolite of benzene. Muconic acid was first isolated from the urine of rabbits and dogs in 1909 (M. Jaffe, Z Physiol Chem 62:58-67). It was originally thought that if muconic acid was formed by the opening of the benzene ring in vivo then the cis-cis isomer should be the initial (and primary) product. However subsequent studies conducted in the 1950s proved that trans-trans-muconic acid is a true metabolite of benzene in mammals (Parke DV, Williams RT. Biochem J 51:339-348 (1952)). Furthermore, dosing rabbits with phenol or catechol also resulted in the urinary excretion of trans-trans-muconic acid. The oxidative ring opening of benzene first gives rise to cis-cis-muconaldehyde, which then isomerizes to cis-trans- and trans-trans-muconaldehyde; the latter is oxidized in vivo to trans-trans-muconic acid. Isomerization of the trans-trans form may take place in vivo to yield small amounts if the cis-cis and cis-trans form of muconic acid. cis-cis-Muconic acid may also be generated from microbial fermentation of benzoic acid. Certain strains of arthobacter are particularly efficient at this process. cis-cis-Muconic acid can also be found in Pseudomonas and Escherichia coli (https://link.springer.com/article/10.1007/BF00250491) (PMID:26360870).

The enzyme aconitase (aconitate hydratase; EC 4.2.1.3) catalyses the stereo-specific isomerization of citrate to isocitrate via cis-aconitate in the tricarboxylic acid cycle. Present in apple fruits, maple syrup and passion fruit juice cis-Aconitic acid, also known as (Z)-aconitic acid, plays several important biological roles: Intermediate in the Citric Acid Cycle: cis-Aconitic acid is an intermediate in the tricarboxylic acid (TCA) cycle, also known as the Krebs cycle or citric acid cycle. It is formed from citrate by the enzyme aconitase and is rapidly converted into isocitrate, another key intermediate in the cycle. The TCA cycle is central to cellular respiration, generating energy-rich molecules like NADH and FADH2. Regulation of Aconitase Activity: The conversion of citrate to cis-aconitate and then to isocitrate by aconitase is an important regulatory step in the TCA cycle. This conversion helps in maintaining the balance of the cycle and is influenced by factors like the energy status of the cell. Role in Cholesterol Synthesis: cis-Aconitic acid is also involved in the synthesis of cholesterol. It serves as a precursor for the synthesis of mevalonate, a key intermediate in the cholesterol biosynthesis pathway. Potential Involvement in Disease: Altered metabolism or accumulation of cis-aconitic acid has been associated with certain diseases, including neurodegenerative disorders and cancer. Its role in these conditions is an area of ongoing research. Plant Growth and Development: In plants, cis-aconitic acid has been found to play a role in growth and development, including seed germination and leaf senescence. In summary, cis-aconitic acid is a crucial intermediate in the TCA cycle, impacting energy production and various metabolic pathways in cells. Its role extends to cholesterol synthesis and potentially to various disease processes, highlighting its importance in cellular metabolism and physiology. cis-Aconitic acid. CAS Common Chemistry.

Mesaconic acid

C5H6O4 (130.0266076)

Mesaconic acid, also known as 2-methylfumarate or citronic acid, belongs to the class of organic compounds known as methyl-branched fatty acids. These are fatty acids with an acyl chain that has a methyl branch. Usually, they are saturated and contain only one or more methyl group. However, branches other than methyl may be present. Mesaconic acid is a dicarboxylic butenoic acid, with a methyl group in position 2 and the double bound between carbons 2 and 3. Mesaconic acid was first studied for its physical properties in 1874 by Jacobus van ‘t Hoff (https://web.archive.org/web/20051117102410/http://dbhs.wvusd.k12.ca.us/webdocs/Chem-History/Van\\%27t-Hoff-1874.html). It is now known to be involved in the biosynthesis of vitamin B12 and it is also a competitor inhibitor of the reduction of fumarate. Mesaconic acid is one of several isomeric carboxylic acids obtained from citric acid. Is used as a fire retardant, recent studies revealed this acid is a competitive inhibitor of fumarate reduction.

Creatine

C4H9N3O2 (131.06947340000002)

Creatine, is a naturally occurring non-protein compound. It belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. Creatine is found in all vertebrates where it facilitates recycling of adenosine triphosphate (ATP). Its primary metabolic role is to combine with a phosphoryl group, via the enzyme creatine kinase, to generate phosphocreatine, which is used to regenerate ATP. Most of the human bodys total creatine and phosphocreatine stores are found in skeletal muscle (95\\\\\%), while the remainder is distributed in the blood, brain, testes, and other tissues. Creatine is not an essential nutrient as it is naturally produced in the human body from the amino acids glycine and arginine, with an additional requirement for methionine to catalyze the transformation of guanidinoacetate to creatine. In the first step of its biosynthesis glycine and arginine are combined by the enzyme arginine:glycine amidinotransferase (AGAT) to form guanidinoacetate, which is then methylated by guanidinoacetate N-methyltransferase (GAMT), using S-adenosyl methionine as the methyl donor. Creatine can also be obtained through the diet at a rate of about 1 gram per day from an omnivorous diet. A cyclic form of creatine, called creatinine, exists in equilibrium with its tautomer and with creatine. Clinically, there are three distinct disorders of creatine metabolism. Deficiencies in the two synthesis enzymes (AGAT and GAMT) can cause L-arginine:glycine amidinotransferase deficiency (caused by variants in AGAT) and guanidinoacetate methyltransferase deficiency (caused by variants in GAMT). Both disorders are inherited in an autosomal recessive manner. A third defect, creatine transporter defect, is caused by mutations in SLC6A8 and inherited in a X-linked manner. Creatine is widely used as a supplement by athletes. Its use can increase maximum power and performance in high-intensity anaerobic repetitive work (periods of work and rest) by 5 to 15\\\\\% (PMID: 24688272). Creatine has no significant effect on aerobic endurance, although it will increase power during short sessions of high-intensity aerobic exercise (PMID: 9662683).

Cysteinylglycine

C5H10N2O3S (178.041211)

Cysteinylglycine is a naturally occurring dipeptide. It is derived from the breakdown of glutathione (a tripeptide). In plasma, cysteinylglycine is in a reduced, oxidized and protein-bound form (aminothiol) and interact via redox and disulphide exchange reactions, in a dynamic system referred to as redox thiol status. (PMID 8642471) Spermatozoa of sub fertile men contain significantly higher thiol concentrations as compared with those of fertile men. The detrimental effect on embryo quality of a high homocysteine (Hcy, another member of the thiol group) concentration in the ejaculate and in follicular fluid is intriguing and may suggest that Hcy is inversely associated with fertility outcome. (PMID 16556671) Rheumatoid arthritis (RA) is a chronic inflammatory disease which involves the synovial membrane of multiple diarthroidal joints causing damage to cartilage and bones. The damage process seems to be related to an overproduction of oxygen reactive species inducing an oxidative perturbation with an increase in some oxidized forms (disulfides and protein mixed disulfides) and a decrease in free thiols. (PMID 15895891) Imipenem (thienamycin formamidine), is a broad-spectrum beta-lactam antibiotic, always used in combination with cilastatin in order to avoid the premature breakdown of imipenem by renal tubular dipeptidase. As this dipeptidase also hydrolyzes the glutathione metabolite cysteinylglycine, the therapeutic association of imipenem and cilastatin causes plasma levels of cysteinylglycine to increase significantly, while cysteine levels are decreased and homocysteine levels are unaffected. Therefore, antibiotic treatment using imipenem-cilastatin induces important metabolic changes that should not remain unrecognized. (PMID 15843241) [HMDB].

C6H12N2O3 (160.0847882)

The ATP-dependent carboxylate-amine/thiol ligase superfamily is known to contain enzymes catalyzing the formation of various types of peptide, one of which is d-alanyl-d-alanine.(PMID: 16030213). The glycopeptide antibiotic vancomycin acts by binding to the D-alanyl-D-alanine terminus of the cell wall precursor lipid II in the cytoplasmic membrane.(PMID: 17418637). D-alanine-D-alanine ligase from Thermotoga maritima ATCC 43589 (TmDdl) was a useful biocatalyst for synthesizing D-amino acid dipeptides.D-Alanine-D-alanine ligase (Ddl) catalyzes the biosynthesis of an essential bacterial peptidoglycan precursor D-alanyl-D-alanine and it represents an important target for development of new antibacterial drugs. (PMID: 17267218). D-Alanyl-D-alanine is a microbial metabolite. Alanyl-alanine, also known as ala-ala or A-a dipeptide, is a member of the class of compounds known as dipeptides. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Alanyl-alanine is soluble (in water) and a weakly acidic compound (based on its pKa). Alanyl-alanine can be found in chives, which makes alanyl-alanine a potential biomarker for the consumption of this food product. Alanyl-alanine can be found primarily in feces. Alanyl-alanine exists in all living organisms, ranging from bacteria to humans. Acquisition and generation of the data is financially supported in part by CREST/JST. D-Ala-D-Ala constitutes the terminus of the peptide part of the peptidoglycan monomer unit and is involved in the transpeptidation reaction as the substrate.

Sphinganine

C18H39NO2 (301.2980634)

Sphinganine, also known as c18-dihydrosphingosine or safingol, is a member of the class of compounds known as 1,2-aminoalcohols. 1,2-aminoalcohols are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. Thus, sphinganine is considered to be a sphingoid base lipid molecule. Sphinganine is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Sphinganine can be found in a number of food items such as agar, biscuit, herbs and spices, and pasta, which makes sphinganine a potential biomarker for the consumption of these food products. Sphinganine can be found primarily in blood, feces, and urine, as well as throughout most human tissues. Sphinganine exists in all eukaryotes, ranging from yeast to humans. In humans, sphinganine is involved in few metabolic pathways, which include globoid cell leukodystrophy, metachromatic leukodystrophy (MLD), and sphingolipid metabolism. Sphinganine is also involved in few metabolic disorders, which include fabry disease, gaucher disease, and krabbe disease. Moreover, sphinganine is found to be associated with pregnancy. Sphinganine is a lyso-sphingolipid protein kinase inhibitor. It has the molecular formula C18H39NO2 and is a colorless solid. Medicinally, safingol has demonstrated promising anticancer potential as a modulator of multi-drug resistance and as an inducer of necrosis. The administration of safingol alone has not been shown to exert a significant effect on tumor cell growth. However, preclinical and clinical studies have shown that combining safingol with conventional chemotherapy agents such as fenretinide, vinblastine, irinotecan and mitomycin C can dramatically potentiate their antitumor effects. Currently in Phase I clinical trials, it is believed to be safe to co-administer with cisplatin . Sphinganine belongs to the class of organic compounds known as 1,2-aminoalcohols. These are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. Thus, sphinganine is considered to be a sphingoid base lipid molecule. Sphinganine is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Sphinganine exists in all living species, ranging from bacteria to humans. Within humans, sphinganine participates in a number of enzymatic reactions. In particular, sphinganine can be converted into 3-dehydrosphinganine through its interaction with the enzyme 3-ketodihydrosphingosine reductase. In addition, sphinganine can be converted into sphinganine 1-phosphate; which is catalyzed by the enzyme sphingosine kinase 2. Outside of the human body, sphinganine has been detected, but not quantified in, several different foods, such as Mexican oregano, jostaberries, winter squash, angelica, and epazotes. This could make sphinganine a potential biomarker for the consumption of these foods. Sphinganine blocks postlysosomal cholesterol transport by inhibiting low-density lipoprotein-induced esterification of cholesterol and causing unesterified cholesterol to accumulate in perinuclear vesicles. It has been suggested that endogenous sphinganine may inhibit cholesterol transport in Niemann-Pick Type C (NPC) disease (PMID: 1817037).

L-Glutamine

C5H10N2O3 (146.069139)

Glutamine (Gln), also known as L-glutamine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. Structurally, glutamine is similar to the amino acid glutamic acid. However, instead of having a terminal carboxylic acid, it has an amide. Glutamine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Glutamine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, polar amino acid. In humans glutamine is considered a non-essential amino acid. Enzymatically, glutamine is formed by replacing a side-chain hydroxyl of glutamic acid with an amine functional group. More specifically, glutamine is synthesized by the enzyme glutamine synthetase from glutamate and ammonia. The most relevant glutamine-producing tissue are skeletal muscles, accounting for about 90\\\\\\% of all glutamine synthesized. Glutamine is also released, in small amounts, by the lungs and brain. In human blood, glutamine is the most abundant free amino acid. Dietary sources of glutamine include protein-rich foods such as beef, chicken, fish, dairy products, eggs, beans, beets, cabbage, spinach, carrots, parsley, vegetable juices, wheat, papaya, Brussels sprouts, celery and kale. Glutamine is one of the few amino acids that can directly cross the blood–brain barrier. Glutamine is often used as a supplement in weightlifting, bodybuilding, endurance and other sports, as well as by those who suffer from muscular cramps or pain, particularly elderly people. In 2017, the U.S. Food and Drug Administration (FDA) approved L-glutamine oral powder, marketed as Endari, to reduce severe complications of sickle cell disease in people aged five years and older with the disorder. Subjects who were treated with L-glutamine oral powder experienced fewer hospital visits for pain treated with a parenterally administered narcotic or ketorolac. The main use of glutamine within the diet of either group is as a means of replenishing the bodys stores of amino acids that have been used during exercise or everyday activities. Studies which have looked into problems with excessive consumption of glutamine thus far have proved inconclusive. However, normal supplementation is healthy mainly because glutamine is supposed to be supplemented after prolonged periods of exercise (for example, a workout or exercise in which amino acids are required for use) and replenishes amino acid stores. This is one of the main reasons glutamine is recommended during fasting or for people who suffer from physical trauma, immune deficiencies, or cancer. There is a significant body of evidence that links glutamine-enriched diets with positive intestinal effects. These include maintenance of gut barrier function, aiding intestinal cell proliferation and differentiation, as well as generally reducing septic morbidity and the symptoms of Irritable Bowel Syndrome (IBS). The reason for such "cleansing" properties is thought to stem from the fact that the intestinal extraction rate of glutamine is higher than that for other amino acids, and is therefore thought to be the most viable option when attempting to alleviate conditions relating to the gastrointestinal tract. These conditions were discovered after comparing plasma concentration within the gut between glutamine-enriched and non glutamine-enriched diets. However, even though glutamine is thought to have "cleansing" properties and effects, it is unknown to what extent glutamine has clinical benefits, due to the varied concentrations of glutamine in varieties of food. It is also known that glutamine has positive effects in reducing healing time after operations. Hospital waiting times after abdominal s... L-glutamine, also known as L-2-aminoglutaramic acid or levoglutamide, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. L-glutamine is soluble (in water) and a moderately acidic compound (based on its pKa). L-glutamine can be found in a number of food items such as acorn, yautia, ohelo berry, and oregon yampah, which makes L-glutamine a potential biomarker for the consumption of these food products. L-glutamine can be found primarily in most biofluids, including blood, sweat, breast milk, and cerebrospinal fluid (CSF), as well as throughout most human tissues. L-glutamine exists in all living species, ranging from bacteria to humans. In humans, L-glutamine is involved in several metabolic pathways, some of which include amino sugar metabolism, the oncogenic action of 2-hydroxyglutarate, mercaptopurine metabolism pathway, and transcription/Translation. L-glutamine is also involved in several metabolic disorders, some of which include the oncogenic action of d-2-hydroxyglutarate in hydroxygluaricaciduria, tay-sachs disease, xanthinuria type I, and adenosine deaminase deficiency. Moreover, L-glutamine is found to be associated with carbamoyl Phosphate Synthetase Deficiency, epilepsy, schizophrenia, and alzheimers disease. L-glutamine is a non-carcinogenic (not listed by IARC) potentially toxic compound. L-glutamine is a drug which is used for nutritional supplementation, also for treating dietary shortage or imbalance. L-Glutamine (L-Glutamic acid 5-amide) is a non-essential amino acid present abundantly throughout the body and involved in many metabolic processes.

Glycerate

C3H6O4 (106.0266076)

Glyceric acid is a colourless syrupy acid, obtained from oxidation of glycerol. It is a compound that is secreted excessively in the urine by patients suffering from D-glyceric aciduria, an inborn error of metabolism, and D-glycerate anemia. Deficiency of human glycerate kinase leads to D-glycerate acidemia/D-glyceric aciduria. Symptoms of the disease include progressive neurological impairment, hypotonia, seizures, failure to thrive, and metabolic acidosis. At sufficiently high levels, glyceric acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Glyceric acid is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of untreated glyceric aciduria. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. Elevated values may also be due to microbial sources such as yeast (Aspergillus, Penicillium, probably Candida) or due to dietary sources containing glycerol (glycerine). Glyceric acid is isolated from various plants (e.g. brassicas, pulses, and Vicia faba). A colorless syrupy acid, obtained from oxidation of glycerol. It is a compound that is secreted excessively in the urine by patients suffering from D-glyceric aciduria and D-glycerate anemia.

L-Cystathionine

C7H14N2O4S (222.0674244)

Cystathionine is a dipeptide formed by serine and homocysteine. Cystathioninuria is a prominent manifestation of vitamin-B6 deficiency. The transsulfuration of methionine yields homocysteine, which combines with serine to form cystathionine, the proximate precursor of cysteine through the enzymatic activity of cystathionase. In conditions in which cystathionine gamma-synthase or cystathionase is deficient, for example, there is cystathioninuria. Although cystathionine has not been detected in normal human serum or plasma by most conventional methods, gas chromatographic/mass spectrometric methodology detected a mean concentration of cystathionine in normal human serum of 140 nM, with a range of 65 to 301 nM. Cystathionine concentrations in CSF have been 10, 1, and 0.5 uM, and "not detected". Only traces (i.e., <1 uM) of cystathionine are present in normal CSF.587. Gamma-cystathionase deficiency (also known as Cystathioninuria), which is an autosomal recessive disorder (NIH: 2428), provided the first instance in which, in a human, the major biochemical abnormality due to a defined enzyme defect was clearly shown to be alleviated by administration of large doses of pyridoxine. The response in gamma-cystathionase-deficient patients is not attributable to correction of a preexisting deficiency of this vitamin (OMMBID, Chap. 88).

L-Arginine

C6H14N4O2 (174.1116704)

Arginine (Arg), also known as L-argninine, belongs to the class of organic compounds known as L-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-asparagine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Arginine is found in all organisms ranging from bacteria to plants to animals. Arginine is an essential amino acid that is physiologically active in the L-form. It is classified as a charged, basic, aliphatic amino acid. Arginine is considered to be a basic amino acid as it has a strongly basic guanidinium group. With a pKa of 12.48, the guanidinium group is positively charged in neutral, acidic, and even most basic environments. Because of the conjugation between the double bond and the nitrogen lone pairs, the positive charge is delocalized. This group is able to form multiple H-bonds. In mammals, arginine is formally classified as a semi-essential or conditionally essential amino acid, depending on the developmental stage and health status of the individual. Infants are unable to effectively synthesize arginine, making it nutritionally essential for infants. Adults, however, are able to synthesize arginine in the urea cycle. L-Arginine is an amino acid that has numerous functions in the body. It helps dispose of ammonia, is used to make compounds such as nitric oxide, creatine, L-glutamate, and L-proline, and it can be converted into glucose and glycogen if needed. Arginine also plays an important role in cell division, immunity and wound healing. Arginine is the immediate precursor of nitric oxide (NO), an important signaling molecule which can act as a second messenger, as well as an intercellular messenger which regulates vasodilation, and also has functions in the immune systems reaction to infection. Nitric oxide is made via the enzyme nitric oxide synthase (PMID 10690324). Arginine is also a precursor for several important nitrogen-containing compounds including urea, ornithine, and agmatine. Arginine is necessary for the synthesis of creatine and can be used for the synthesis of polyamines (mainly through ornithine and to a lesser degree through agmatine, citrulline, and glutamate.) The presence of asymmetric dimethylarginine (ADMA) in serum or plasma, a close relative of argninine, inhibits the nitric oxide synthase reaction. ADMA is considered a marker for vascular disease, just as L-arginine is considered a sign of a healthy endothelium. In large doses, L-arginine also stimulates the release of the hormones growth hormone and prolactin. Arginine is a known inducer of mTOR (mammalian target of rapamycin) and is responsible for inducing protein synthesis through the mTOR pathway. mTOR inhibition by rapamycin partially reduces arginine-induced protein synthesis (PMID: 20841502). Catabolic disease states such as sepsis, injury, and cancer cause an increase in arginine utilization, which can exceed normal body production, leading to arginine depletion. Arginine also activates AMP kinase (AMPK) which then stimulates skeletal muscle fatty acid oxidation and muscle glucose uptake, thereby increasing insulin secretion by pancreatic beta-cells (PMID: 21311355). Arginine is found in plant and animal proteins, such as dairy products, meat, poultry, fish, and nuts. The ratio of L-arginine to lysine is also important: soy and other plant proteins have more L-arginine than animal sources of protein. [Spectral] L-Arginine (exact mass = 174.11168) and L-Histidine (exact mass = 155.06948) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX.

Homocysteine

C4H9NO2S (135.0353974)

A high level of blood serum homocysteine is a powerful risk factor for cardiovascular disease. Unfortunately, one study which attempted to decrease the risk by lowering homocysteine was not fruitful. This study was conducted on nearly 5000 Norwegian heart attack survivors who already had severe, late-stage heart disease. No study has yet been conducted in a preventive capacity on subjects who are in a relatively good state of health.; Elevated levels of homocysteine have been linked to increased fractures in elderly persons. The high level of homocysteine will auto-oxidize and react with reactive oxygen intermediates and damage endothelial cells and has a higher risk to form a thrombus. Homocysteine does not affect bone density. Instead, it appears that homocysteine affects collagen by interfering with the cross-linking between the collagen fibers and the tissues they reinforce. Whereas the HOPE-2 trial showed a reduction in stroke incidence, in those with stroke there is a high rate of hip fractures in the affected side. A trial with 2 homocysteine-lowering vitamins (folate and B12) in people with prior stroke, there was an 80\\\\\\% reduction in fractures, mainly hip, after 2 years. Interestingly, also here, bone density (and the number of falls) were identical in the vitamin and the placebo groups.; Homocysteine is a sulfur-containing amino acid that arises during methionine metabolism. Although its concentration in plasma is only about 10 micromolar (uM), even moderate hyperhomocysteinemia is associated with increased incidence of cardiovascular disease and Alzheimers disease. Elevations in plasma homocysteine are commonly found as a result of vitamin deficiencies, polymorphisms of enzymes of methionine metabolism, and renal disease. Pyridoxal, folic acid, riboflavin, and Vitamin B(12) are all required for methionine metabolism, and deficiency of each of these vitamins result in elevated plasma homocysteine. A polymorphism of methylenetetrahydrofolate reductase (C677T), which is quite common in most populations with a homozygosity rate of 10-15 \\\\\\%, is associated with moderate hyperhomocysteinemia, especially in the context of marginal folate intake. Plasma homocysteine is inversely related to plasma creatinine in patients with renal disease. This is due to an impairment in homocysteine removal in renal disease. The role of these factors, and of modifiable lifestyle factors, in affecting methionine metabolism and in determining plasma homocysteine levels is discussed. Homocysteine is an independent cardiovascular disease (CVD) risk factor modifiable by nutrition and possibly exercise. Homocysteine was first identified as an important biological compound in 1932 and linked with human disease in 1962 when elevated urinary homocysteine levels were found in children with mental retardation. This condition, called homocysteinuria, was later associated with premature occlusive CVD, even in children. These observations led to research investigating the relationship of elevated homocysteine levels and CVD in a wide variety of populations including middle age and elderly men and women with and without traditional risk factors for CVD. (PMID 17136938, 15630149); Homocysteine is an amino acid with the formula HSCH2CH2CH(NH2)CO2H. It is a homologue of the amino acid cysteine, differing by an additional methylene (-CH2-) group. It is biosynthesized from methionine by the removal of its terminal C? methyl group. Homocysteine can be recycled into methionine or converted into cysteine with the aid of B-vitamins.; Studies reported in 2006 have shown that giving vitamins [folic acid, B6 and B12] to reduce homocysteine levels may not quickly offer benefit, however a significant 25\\\\\\% reduction in stroke was found in the HOPE-2 study even in patients mostly with existing serious arterial decline although the overall death rate was not significantly changed by the intervention in the trial. Clearly, reducing homocysteine does not quickly repair existing... Homocysteine (CAS: 454-29-5) is a sulfur-containing amino acid that arises during methionine metabolism.

Additionally some of the peaks in this data contains dimers and other unidentified ions. Homocysteine is biosynthesized naturally via a multi-step process.[9] First, methionine receives an adenosine group from ATP, a reaction catalyzed by S-adenosyl-methionine synthetase, to give S-adenosyl methionine (SAM-e). SAM-e then transfers the methyl group to an acceptor molecule, (e.g., norepinephrine as an acceptor during epinephrine synthesis, DNA methyltransferase as an intermediate acceptor in the process of DNA methylation). The adenosine is then hydrolyzed to yield L-homocysteine. L-Homocysteine has two primary fates: conversion via tetrahydrofolate (THF) back into L-methionine or conversion to L-cysteine.[10] Biosynthesis of cysteine Mammals biosynthesize the amino acid cysteine via homocysteine. Cystathionine β-synthase catalyses the condensation of homocysteine and serine to give cystathionine. This reaction uses pyridoxine (vitamin B6) as a cofactor. Cystathionine γ-lyase then converts this double amino acid to cysteine, ammonia, and α-ketobutyrate. Bacteria and plants rely on a different pathway to produce cysteine, relying on O-acetylserine.[11] Methionine salvage Homocysteine can be recycled into methionine. This process uses N5-methyl tetrahydrofolate as the methyl donor and cobalamin (vitamin B12)-related enzymes. More detail on these enzymes can be found in the article for methionine synthase. Other reactions of biochemical significance Homocysteine can cyclize to give homocysteine thiolactone, a five-membered heterocycle. Because of this "self-looping" reaction, homocysteine-containing peptides tend to cleave themselves by reactions generating oxidative stress.[12] Homocysteine also acts as an allosteric antagonist at Dopamine D2 receptors.[13] It has been proposed that both homocysteine and its thiolactone may have played a significant role in the appearance of life on the early Earth.[14] L-Homocysteine.

Hypoxanthine

C5H4N4O (136.03850939999998)

Hypoxanthine, also known as purine-6-ol or Hyp, belongs to the class of organic compounds known as purines. Purines are a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. Hypoxanthine is also classified as an oxopurine, Hypoxanthine is a naturally occurring purine derivative and a reaction intermediate in the metabolism of adenosine and in the formation of nucleic acids by the nucleotide salvage pathway. Hypoxanthine exists in all living species, ranging from bacteria to plants to humans. Hypoxanthine has been detected, but not quantified in, several different foods, such as radish (var.), mountain yams, welsh onions, greenthread tea, and common beets. Hypoxanthine is occasionally found as a constituent of nucleic acids, where it is present in the anticodon of tRNA in the form of its nucleoside inosine. Biologically, hypoxanthine can be formed a number of ways. For instance, it is one of the products of the action of xanthine oxidase on xanthine. However, more frequently xanthine is formed from oxidation of hypoxanthine by xanthine oxidoreductase. The enzyme hypoxanthine-guanine phosphoribosyltransferase converts hypoxanthine into IMP in the nucleotide salvage pathway. Hypoxanthine is also a spontaneous deamination product of adenine. Under normal circumstances hypoxanthine is readily converted to uric acid. In this process, hypoxanthine is first oxidized to xanthine, which is further oxidized to uric acid by xanthine oxidase. Molecular oxygen, the oxidant in both reactions, is reduced to H2O2 and other reactive oxygen species. In humans, uric acid is the final product of purine degradation and is excreted in the urine. Within humans, hypoxanthine participates in a number of other enzymatic reactions. In particular, hypoxanthine and ribose 1-phosphate can be biosynthesized from inosine through its interaction with the enzyme purine nucleoside phosphorylase. Hypoxanthine is also involved in the metabolic disorder called the purine nucleoside phosphorylase deficiency. Purine nucleoside phosphorylase (PNP) deficiency is a disorder of the immune system (primary immunodeficiency) characterized by recurrent infections, neurologic symptoms, and autoimmune disorders. PNP deficiency causes a shortage of white blood cells, called T-cells, that help fight infection. Affected individuals develop neurologic symptoms, such as stiff or rigid muscles (spasticity), uncoordinated movements (ataxia), developmental delay, and intellectual disability. PNP deficiency is associated with an increased risk to develop autoimmune disorders, such as autoimmune hemolytic anemia, idiopathic thrombocytopenic purpura (ITP), autoimmune neutropenia, thyroiditis, and lupus.

Indoleacetic acid

C10H9NO2 (175.0633254)

Indoleacetic acid (IAA) is a breakdown product of tryptophan metabolism and is often produced by the action of bacteria in the mammalian gut. Higher levels of IAA are associated with bacteria from Clostridium species including C. stricklandii, C. lituseburense, C. subterminale, and C. putrefaciens (PMID: 12173102). IAA can be found in Agrobacterium, Azospirillum, Bacillus, Bradyrhizobium, Clostridium, Enterobacter, Pantoea, Pseudomonas, Rhizobium (PMID: 12173102, PMID: 17555270, PMID: 12147474, PMID: 19400643, PMID: 9450337, PMID: 21397014) (https://link.springer.com/chapter/10.1007/978-1-4612-3084-7_7) (https://escholarship.org/uc/item/1bf1b5m3). Some endogenous production of IAA in mammalian tissues also occurs. It may be produced by the decarboxylation of tryptamine or the oxidative deamination of tryptophan. IAA frequently occurs at low levels in urine and has been found in elevated levels in the urine of patients with phenylketonuria (PMID: 13610897). IAA has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Using material extracted from human urine, it was discovered by Kogl in 1933 that indoleacetic acid is also an important plant hormone (PMID: 13610897). Specifically, IAA is a member of the group of phytohormones called auxins. IAA is generally considered to be the most important native auxin. Plant cells synthesize IAA from tryptophan (Wikipedia). IAA and some derivatives can be oxidized by horseradish peroxidase (HRP) into cytotoxic species. IAA is only toxic after oxidative decarboxylation; the effect of IAA/HRP is thought to be due in part to the formation of methylene-oxindole, which may conjugate with DNA bases and protein thiols. IAA/HRP could be used as the basis for targeted cancer, a potential new role for plant auxins in cancer therapy (PMID: 11163327). 1h-indol-3-ylacetic acid, also known as (indol-3-yl)acetate or heteroauxin, belongs to indole-3-acetic acid derivatives class of compounds. Those are compounds containing an acetic acid (or a derivative) linked to the C3 carbon atom of an indole. 1h-indol-3-ylacetic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 1h-indol-3-ylacetic acid is a mild, odorless, and sour tasting compound and can be found in a number of food items such as sweet bay, chinese bayberry, winter squash, and linden, which makes 1h-indol-3-ylacetic acid a potential biomarker for the consumption of these food products. 1h-indol-3-ylacetic acid can be found primarily in most biofluids, including blood, feces, saliva, and urine, as well as throughout most human tissues. 1h-indol-3-ylacetic acid exists in all living species, ranging from bacteria to humans. In humans, 1h-indol-3-ylacetic acid is involved in the tryptophan metabolism.

Isorhamnetin

C16H12O7 (316.05830019999996)

Isorhamnetin is the methylated metabolite of quercetin. Quercetin is an important dietary flavonoid with in vitro antioxidant activity. However, it is found in human plasma as conjugates with glucuronic acid, sulfate or methyl groups, with no significant amounts of free quercetin present. Isorhamnetin prevents endothelial cell injuries from oxidized LDL via inhibition of lectin-like ox-LDL receptor-1 upregulation, interference of ox-LDL-mediated intracellular signaling pathway (p38MAPK activation, NF-kappaB nuclear translocation, eNOS expression) and the antioxidant activity of isorhamnetin. Isorhamnetin prevents endothelial dysfunction, superoxide production, and overexpression of p47phox induced by angiotensin II. Isorhamnetin appears to be a potent drug against esophageal cancer due to its in vitro potential to not only inhibit proliferation but also induce apoptosis of Eca-109 cells. (PMID: 15493462, 17368593, 17374653, 16963021). Isorhamnetin is a monomethoxyflavone that is quercetin in which the hydroxy group at position 3 is replaced by a methoxy group. It has a role as an EC 1.14.18.1 (tyrosinase) inhibitor, an anticoagulant and a metabolite. It is a 7-hydroxyflavonol, a tetrahydroxyflavone and a monomethoxyflavone. It is functionally related to a quercetin. It is a conjugate acid of an isorhamnetin(1-). Isorhamnetin is a natural product found in Lotus ucrainicus, Strychnos pseudoquina, and other organisms with data available.

L-Aspartic acid

C4H7NO4 (133.0375062)

Aspartic acid (Asp), also known as L-aspartic acid or as aspartate, the name of its anion, is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-aspartic acid is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Aspartic acid is found in all organisms ranging from bacteria to plants to animals. It is classified as an acidic, charged (at physiological pH), aliphatic amino acid. In humans, aspartic acid is a nonessential amino acid derived from glutamic acid by enzymes using vitamin B6. However, in the human body, aspartate is most frequently synthesized through the transamination of oxaloacetate. A non-essential amino acid is an amino acid that can be synthesized from central metabolic pathway intermediates in humans and is not required in the diet. As its name indicates, aspartic acid is the carboxylic acid analog of asparagine. The D-isomer of aspartic acid (D-aspartic acid) is one of two D-amino acids commonly found in mammals. Aspartic acid was first discovered in 1827 by Auguste-Arthur Plisson and Étienne Ossian Henry by hydrolysis of asparagine, which had been isolated from asparagus juice in 1806. Aspartate has many biochemical roles. It is a neurotransmitter, a metabolite in the urea cycle and it participates in gluconeogenesis. It carries reducing equivalents in the malate-aspartate shuttle, which utilizes the ready interconversion of aspartate and oxaloacetate, which is the oxidized (dehydrogenated) derivative of malic acid. Aspartate donates one nitrogen atom in the biosynthesis of inosine, the precursor to the purine bases which are key to DNA biosynthesis. In addition, aspartic acid acts as a hydrogen acceptor in a chain of ATP synthase. Aspartic acid is a major excitatory neurotransmitter, which is sometimes found to be increased in epileptic and stroke patients. It is decreased in depressed patients and in patients with brain atrophy. As a neurotransmitter, aspartic acid may provide resistance to fatigue and thus lead to endurance, although the evidence to support this idea is not strong (Wikipedia). Aspartic acid supplements are being evaluated. Five grams can raise blood levels. Magnesium and zinc may be natural inhibitors of some of the actions of aspartic acid. Aspartic acid, when chemically coupled with the amino acid D-phenylalanine, is a part of a natural sweetener, aspartame. This sweetener is an advance in artificial sweeteners, and is probably safe in normal doses to all except phenylketonurics. Aspartic acid may be a significant immunostimulant of the thymus and can protect against some of the damaging effects of radiation. Aspartic acid is found in higher abundance in: oysters, luncheon meats, sausage meat, wild game, sprouting seeds, oat flakes, avocado, asparagus, young sugarcane, and molasses from sugar beets.

L-Cystine

C6H12N2O4S2 (240.0238472)

Cystine is an oxidized dimeric form of cysteine. It is formed by linking two cysteine residues via a disulfide bond (Cys-S-S-Cys) between the -SH groups. Cystine is found in high concentrations in digestive enzymes and in the cells of the immune system, skeletal and connective tissues, skin, and hair. Hair and skin are 10-14\\\% cystine. Cystine is the preferred form of cysteine for the synthesis of glutathione in cells involved in the immune system (e.g. macrophages and astrocytes). Lymphocytes and neurons prefer cysteine for glutathione production. Optimizing glutathione levels in macrophages and astrocytes with cystine allows these cells to provide cysteine to lymphocytes and neurons directly upon demand (Wikipedia). (-)-Cystine.

L-Histidine

C6H9N3O2 (155.0694734)

Histidine (His), also known as L-histidine, is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. Histidine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Histidine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, positively charged or basic amino acid. Histidine is a unique amino acid with an imidazole functional group. The acid-base properties of the imidazole side chain are relevant to the catalytic mechanism of many enzymes such as proteases. In catalytic triads, the basic nitrogen of histidine abstracts a proton from serine, threonine, or cysteine to activate it as a nucleophile. In a histidine proton shuttle, histidine is used to quickly shuttle protons. It can do this by abstracting a proton with its basic nitrogen to make a positively charged intermediate and then use another molecule to extract the proton from its acidic nitrogen. Histidine forms complexes with many metal ions. The imidazole sidechain of the histidine residue commonly serves as a ligand in metalloproteins. Histidine was first isolated by German physician Albrecht Kossel in 1896. Histidine is an essential amino acid in humans and other mammals. It was initially thought that it was only essential for infants, but longer-term studies established that it is also essential for adults. Infants four to six months old require 33 mg/kg of histidine. It is not clear how adults make small amounts of histidine, and dietary sources probably account for most of the histidine in the body. Histidine is a precursor for histamine and carnosine biosynthesis. Inborn errors of histidine metabolism, including histidinemia, maple syrup urine disease, propionic acidemia, and tyrosinemia I, exist and are marked by increased histidine levels in the blood. Elevated blood histidine is accompanied by a wide range of symptoms, from mental and physical retardation to poor intellectual functioning, emotional instability, tremor, ataxia and psychosis. Histidine and other imidazole compounds have anti-oxidant, anti-inflammatory and anti-secretory properties (PMID: 9605177 ). The efficacy of L-histidine in protecting inflamed tissue is attributed to the capacity of the imidazole ring to scavenge reactive oxygen species (ROS) generated by cells during acute inflammatory response (PMID: 9605177 ). Histidine, when administered in therapeutic quantities is able to inhibit cytokines and growth factors involved in cell and tissue damage (US patent 6150392). Histidine in medical therapies has its most promising trials in rheumatoid arthritis where up to 4.5 g daily have been used effectively in severely affected patients. Arthritis patients have been found to have low serum histidine levels, apparently because of very rapid removal of histidine from their blood (PMID: 1079527 ). Other patients besides arthritis patients that have been found to be low in serum histidine are those with chronic renal failure. Urinary levels of histidine are reduced in pediatric patients with pneumonia (PMID: 2084459 ). Asthma patients exhibit increased serum levels of histidine over normal controls (PMID: 23517038 ). Serum histidine levels are lower and are negatively associated with inflammation and oxidative stress in obese women (PMID: 23361591 ). Histidine supplementation has been shown to reduce insulin resistance, reduce BMI and fat mass and suppress inflammation and oxidative stress in obese women with metabolic syndrome. Histidine appears to suppress pro-inflammatory cytokine expression, possibly via the NF-κB pathway, in adipocytes (PMID: 23361591 ). Low plasma concentrations of histidine are associated with protein-energy...

DL-Homocystine

C8H16N2O4S2 (268.0551456)

Homocystine is the oxidized form of homocysteine. Homocystine is a dipeptide consisting of two homocysteine molecules joined by a disulfide bond. Homocysteine is a sulfur-containing amino acid that arises during methionine metabolism. Homocystine occurs only transiently before being reduced to homocysteine and converted to the harmless cystathionine via a vitamin B6-dependent enzyme. Homocystine and homocysteine-cysteine mixed disulfides account for >98\\\\\% of total homocysteine in plasma from healthy individuals (PMID 11592966). Homocystine has been shown to stereospecifically induce endothelial nitric oxide synthase-dependent lipid peroxidation in endothelial cells, thereby inducing a vascular cell type-specific oxidative stress. This vascular stress is associated with atherothrombotic cardiovascular disease (PMID: 14980706). High levels of homocysteine (and homocysteine) can be found in individuals suffering from homocystinura due to cystathionine synthase deficiency (PMID: 4685596) Homocystine is the double-bonded form of homocysteine, but it occurs only transiently before being converted to the harmless cystathionine via a vitamin B6-dependent enzyme.

L-Homoserine

C4H9NO3 (119.0582404)

L-homoserine, also known as 2-amino-4-hydroxybutanoic acid or isothreonine, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. L-homoserine is soluble (in water) and a moderately acidic compound (based on its pKa). L-homoserine can be found in common pea, which makes L-homoserine a potential biomarker for the consumption of this food product. L-homoserine can be found primarily in blood, feces, and urine, as well as in human prostate tissue. L-homoserine exists in all living species, ranging from bacteria to humans. In humans, L-homoserine is involved in the methionine metabolism. L-homoserine is also involved in several metabolic disorders, some of which include glycine n-methyltransferase deficiency, hypermethioninemia, cystathionine beta-synthase deficiency, and methylenetetrahydrofolate reductase deficiency (MTHFRD). Homoserine (also called isothreonine) is an α-amino acid with the chemical formula HO2CCH(NH2)CH2CH2OH. L-Homoserine is not one of the common amino acids encoded by DNA. It differs from the proteinogenic amino acid serine by insertion of an additional -CH2- unit into the backbone. Homoserine, or its lactone form, is the product of a cyanogen bromide cleavage of a peptide by degradation of methionine . Homoserine is a more reactive variant of the amino acid serine. In this variant, the hydroxyl side chain contains an additional CH2 group which brings the hydroxyl group closer to its own carboxyl group, allowing it to chemically react to form a five-membered ring. This occurs at the point that amino acids normally join to their neighbours in a peptide bond. Homoserine is therefore unsuitable for forming proteins and has been eliminated from the repertoire of amino acids used by living things. Homoserine is the final product on the C-terminal end of the N-terminal fragment following a cyanogen bromide cleavage. (wikipedia). Homoserine is also a microbial metabolite. L-Homoserine.

Saccharopine

C11H20N2O6 (276.13213)

Saccharopine is an intermediate in the degradation of lysine, formed by the condensation of lysine and alpha-ketoglutarate. The saccharopine pathway is the main route for lysine degradation in mammals, and its first two reactions are catalyzed by enzymatic activities known as lysine-oxoglutarate reductase (LOR) and saccharopine dehydrogenase (SDH), which reside on a single bifunctional polypeptide (LOR/SDH) (EC 1.5.1.8). The reactions involved with saccharopine dehydrogenases have very strict substrate specificity for L-lysine, 2-oxoglutarate, and NADPH. LOR/SDH has been detected in a number of mammalian tissues, mainly in the liver and kidney, contributing not only to the general nitrogen balance in the organism but also to the controlled conversion of lysine into ketone bodies. A tetrameric form has also been observed in human liver and placenta. LOR activity has also been detected in brain mitochondria during embryonic development, and this opens up the question of whether or not lysine degradation has any functional significance during brain development. As a result, there is now a new focus on the nutritional requirements for lysine in gestation and infancy. Finally, LOR and/or SDH deficiencies seem to be involved in a human autosomal genetic disorder known as familial hyperlysinemia, which is characterized by serious defects in the functioning of the nervous system and characterized by a deficiency in lysine-ketoglutarate reductase, saccharopine dehydrogenase, and saccharopine oxidoreductase activities. Saccharopinuria (high amounts of saccharopine in the urine) and saccharopinemia (an excess of saccharopine in the blood) are conditions present in some inherited disorders of lysine degradation (PMID: 463877, 10567240, 10772957, 4809305). If present in sufficiently high levels, saccharopine can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Saccharopine is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). Many affected children with organic acidemias experience intellectual disability or delayed development. Amino acid from Saccharomyces cerevisiae and Neurospora crassaand is also found in mushrooms and seeds

L-Serine

C3H7NO3 (105.0425912)

Serine (Ser) or L-serine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-serine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Serine is found in all organisms ranging from bacteria to plants to animals. It is classified as a polar, uncharged (at physiological pH), aliphatic amino acid. In humans, serine is a nonessential amino acid that can be easily derived from glycine. A non-essential amino acid is an amino acid that can be synthesized from central metabolic pathway intermediates in humans and is not required in the diet. Like all the amino acid building blocks of protein and peptides, serine can become essential under certain conditions, and is thus important in maintaining health and preventing disease. L-Serine may be derived from four possible sources: dietary intake; biosynthesis from the glycolytic intermediate 3-phosphoglycerate; from glycine; and by protein and phospholipid degradation. Little data is available on the relative contributions of each of these four sources of l-serine to serine homoeostasis. It is very likely that the predominant source of l-serine will be very different in different tissues and during different stages of human development. In the biosynthetic pathway, the glycolytic intermediate 3-phosphoglycerate is converted into phosphohydroxypyruvate, in a reaction catalyzed by 3-phosphoglycerate dehydrogenase (3- PGDH; EC 1.1.1.95). Phosphohydroxypyruvate is metabolized to phosphoserine by phosphohydroxypyruvate aminotransferase (EC 2.6.1.52) and, finally, phosphoserine is converted into l-serine by phosphoserine phosphatase (PSP; EC 3.1.3.3). In liver tissue, the serine biosynthetic pathway is regulated in response to dietary and hormonal changes. Of the three synthetic enzymes, the properties of 3-PGDH and PSP are the best documented. Hormonal factors such as glucagon and corticosteroids also influence 3-PGDH and PSP activities in interactions dependent upon the diet. L-serine is the predominant source of one-carbon groups for the de novo synthesis of purine nucleotides and deoxythymidine monophosphate. It has long been recognized that, in cell cultures, L-serine is a conditional essential amino acid, because it cannot be synthesized in sufficient quantities to meet the cellular demands for its utilization. In recent years, L-serine and the products of its metabolism have been recognized not only to be essential for cell proliferation, but also to be necessary for specific functions in the central nervous system. The findings of altered levels of serine and glycine in patients with psychiatric disorders and the severe neurological abnormalities in patients with defects of L-serine synthesis underscore the importance of L-serine in brain development and function.

L-Lysine

C6H14N2O2 (146.1055224)

Lysine (Lys), also known as L-lysine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. Lysine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Lysine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, positively charged or basic amino acid. In humans, lysine is an essential amino acid, meaning the body cannot synthesize it, and it must be obtained from the diet. Lysine is high in foods such as wheat germ, cottage cheese and chicken. Of meat products, wild game and pork have the highest concentration of lysine. Fruits and vegetables contain little lysine, except avocados. Normal requirements for lysine have been found to be about 8 g per day or 12 mg/kg in adults. Children and infants need more, 44 mg/kg per day for an eleven to-twelve-year old, and 97 mg/kg per day for three-to six-month old. In organisms that synthesise lysine, it has two main biosynthetic pathways, the diaminopimelate and α-aminoadipate pathways, which employ distinct enzymes and substrates and are found in diverse organisms. Lysine catabolism occurs through one of several pathways, the most common of which is the saccharopine pathway. Lysine plays several roles in humans, most importantly proteinogenesis, but also in the crosslinking of collagen polypeptides, uptake of essential mineral nutrients, and in the production of carnitine, which is key in fatty acid metabolism. Lysine is also often involved in histone modifications, and thus, impacts the epigenome. Lysine is highly concentrated in muscle compared to most other amino acids. Normal lysine metabolism is dependent upon many nutrients including niacin, vitamin B6, riboflavin, vitamin C, glutamic acid and iron. Excess arginine antagonizes lysine. Several inborn errors of lysine metabolism are known, such as cystinuria, hyperdibasic aminoaciduria I, lysinuric protein intolerance, propionic acidemia, and tyrosinemia I. Most are marked by mental retardation with occasional diverse symptoms such as absence of secondary sex characteristics, undescended testes, abnormal facial structure, anemia, obesity, enlarged liver and spleen, and eye muscle imbalance. Lysine also may be a useful adjunct in the treatment of osteoporosis. Although high protein diets result in loss of large amounts of calcium in urine, so does lysine deficiency. Lysine may be an adjunct therapy because it reduces calcium losses in urine. Lysine deficiency also may result in immunodeficiency. Requirements for lysine are probably increased by stress. Lysine toxicity has not occurred with oral doses in humans. Lysine dosages are presently too small and may fail to reach the concentrations necessary to prove potential therapeutic applications. Lysine metabolites, amino caproic acid and carnitine have already shown their therapeutic potential. Thirty grams daily of amino caproic acid has been used as an initial daily dose in treating blood clotting disorders, indicating that the proper doses of lysine, its precursor, have yet to be used in medicine. Low lysine levels have been found in patients with Parkinsons, hypothyroidism, kidney disease, asthma and depression. The exact significance of these levels is unclear, yet lysine therapy can normalize the level and has been associated with improvement of some patients with these conditions. Abnormally elevated hydroxylysines have been found in virtually all chronic degenerative diseases and those treated with coumadin therapy. The levels of this stress marker may be improved by high doses of vitamin C. Lysine is particularly useful in therapy for marasmus (wasting) (http://www.dcnutrition.com). Lysine has also been sh...

L-Methionine

C5H11NO2S (149.0510466)

Methionine (Met), also known as L-methionine, is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. Methionine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Methionine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, non-polar amino acid. Methionine is an essential amino acid (there are 9 essential amino acids), meaning the body cannot synthesize it, and it must be obtained from the diet. It is required for normal growth and development of humans, other mammals, and avian species. In addition to being a substrate for protein synthesis, methionine is an intermediate in transmethylation reactions, serving as the major methyl group donor in vivo, including the methyl groups for DNA and RNA intermediates. Methionine is a methyl acceptor for 5-methyltetrahydrofolate-homocysteine methyltransferase (methionine synthase), the only reaction that allows for the recycling of this form of folate, and is also a methyl acceptor for the catabolism of betaine. Methionine is the metabolic precursor for cysteine. Only the sulfur atom from methionine is transferred to cysteine; the carbon skeleton of cysteine is donated by serine (PMID: 16702340 ). There is a general consensus concerning normal sulfur amino acid (SAA) requirements. WHO recommendations amount to 13 mg/kg per 24 h in healthy adults. This amount is roughly doubled in artificial nutrition regimens. In disease or after trauma, requirements may be altered for methionine, cysteine, and taurine. Although in specific cases of congenital enzyme deficiency, prematurity, or diminished liver function, hypermethioninemia or hyperhomocysteinemia may occur, SAA supplementation can be considered safe in amounts exceeding 2-3 times the minimum recommended daily intake. Apart from some very specific indications (e.g. acetaminophen poisoning) the usefulness of SAA supplementation is not yet established (PMID: 16702341 ). Methionine is known to exacerbate psychopathological symptoms in schizophrenic patients, but there is no evidence of similar effects in healthy subjects. The role of methionine as a precursor of homocysteine is the most notable cause for concern. Acute doses of methionine can lead to acute increases in plasma homocysteine, which can be used as an index of the susceptibility to cardiovascular disease. Sufficiently high doses of methionine can actually result in death. Longer-term studies in adults have indicated no adverse consequences of moderate fluctuations in dietary methionine intake, but intakes higher than 5 times the normal amount resulted in elevated homocysteine levels. These effects of methionine on homocysteine and vascular function are moderated by supplements of vitamins B-6, B-12, C, and folic acid (PMID: 16702346 ). When present in sufficiently high levels, methionine can act as an atherogen and a metabotoxin. An atherogen is a compound that when present at chronically high levels causes atherosclerosis and cardiovascular disease. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of methionine are associated with at least ten inborn errors of metabolism, including cystathionine beta-synthase deficiency, glycine N-methyltransferase deficiency, homocystinuria, tyrosinemia, galactosemia, homocystinuria-megaloblastic anemia due to defects in cobalamin metabolism, methionine adenosyltransferase deficiency, methylenetetrahydrofolate reductase deficiency, and S-adenosylhomocysteine (SAH) hydrolase deficiency.

C5H11NO3S (165.0459616)

Methionine sulfoxide belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Methionine sulfoxide exists in all living species, ranging from bacteria to humans. Within humans, methionine sulfoxide participates in a number of enzymatic reactions. In particular, methionine sulfoxide can be biosynthesized from L-methionine through its interaction with the enzyme methionine-R-sulfoxide reductase B3. In addition, methionine sulfoxide can be biosynthesized from L-methionine through the action of the enzyme methionine-R-sulfoxide reductase b2, mitochondrial. In humans, methionine sulfoxide is involved in the metabolic disorder called hypermethioninemia. Methionine sulfoxide is an oxidation product of methionine with reactive oxygen species via 2-electron-dependent mechanism. Such oxidants can be generated from activated neutrophils; therefore, methionine sulfoxide can be regarded as a biomarker of oxidative stress in vivo. (PMID 12576054) [HMDB]. Methionine sulfoxide is found in many foods, some of which are romaine lettuce, white cabbage, dill, and yellow bell pepper.

Nα-Acetyl-L-lysine

C8H16N2O3 (188.1160866)

N-epsilon-Acetyl-L-lysine also known as Nepsilon-Acetyllysine or N6-Acetyllysine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at one of its nitrogen atoms. N-epsilon-Acetyl-L-lysine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-epsilon-Acetyl-L-lysine is a biologically available sidechain, N-capped form of the proteinogenic alpha amino acid L-lysine. Unlike L-lysine, acetylated lysine derivatives such as N-epsilon-Acetyl-L-lysine are zwitterionic compounds. These are molecules that contains an equal number of positively- and negatively-charged functional groups. N-epsilon-Acetyl-L-lysine is found naturally in eukaryotes ranging from yeast to plants to humans. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins (often histones) by specific hydrolases. N-epsilon-Acetyl-L-lysine can be biosynthesized from L-lysine and acetyl-CoA via the enzyme known as Lysine N-acetyltransferase. Post-translational lysine-acetylation is one of two major modifications of lysine residues in various proteins – either N-terminal or N-alpha acetylation or N6 (sidechain) acetylation. Side-chain acetylation of specific lysine residues in the N-terminal domains of core histones is a biochemical marker of active genes. Acetylation is now known to play a major role in eukaryotic transcription. Specifically, acetyltransferase enzymes that act on particular lysine side chains of histones and other proteins are intimately involved in transcriptional activation. By modifying chromatin proteins and transcription-related factors, these acetylases are believed to regulate the transcription of many genes. The best-characterized mechanism is acetylation, catalyzed by histone acetyltransferase (HAT) enzymes. HATs function enzymatically by transferring an acetyl group from acetyl-coenzyme A (acetyl-CoA) to the amino group of certain lysine side chains within a histones basic N-terminal tail region. Within a histone octamer, these regions extend out from the associated globular domains, and in the context of a nucleosome, they are believed to bind the DNA through charge interactions (positively charged histone tails associated with negatively charged DNA) or mediate interactions between nucleosomes. Lysine acetylation, which neutralizes part of a tail regions positive charge, is postulated to weaken histone-DNA or nucleosome-nucleosome interactions and/or signal a conformational change, thereby destabilizing nucleosome structure or arrangement and giving other nuclear factors, such as the transcription complex, more access to a genetic locus. In agreement with this is the fact that acetylated chromatin has long been associated with states of transcriptional activation. Specific recognition of N6-acetyl-L-lysine is a conserved function of all bromodomains found in different proteins, recognized as an emerging intracellular signalling mechanism that plays critical roles in regulating gene transcription, cell-cycle progression, apoptosis, DNA repair, and cytoskeletal organization (PMID: 9169194 , 10827952 , 17340003 , 16247734 , 9478947 , 10839822 ). N-acetylated amino acids, such as N-epsilon-Acetyl-L-lysine can be released by an N-acylpeptide hydrolase from histones going through proteolytic degradation (PMID: 16465618). Many N-acetylamino acids are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). Isolated from sugarbeet (Beta vulgaris) KEIO_ID A174 Nepsilon-Acetyl-L-lysine is a derivative of the amino acid lysine.

N-Acetyl-L-glutamate can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetyl-L-glutamate is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-glutamic acid. N-Acetyl-L-glutamic acid is found in all organisms ranging from bacteria to plants to animals. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\\% of all human proteins and 68\\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetylglutamate can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free glutamic acid can also occur. In particular, N-Acetyl-L-glutamic acid can be biosynthesized from glutamate and acetylornithine by ornithine acetyltransferase, and from glutamic acid and acetyl-CoA by the enzyme known as N-acetylglutamate synthase. N-Acetyl-L-glutamic acid is the first intermediate involved in the biosynthesis of arginine in prokaryotes and simple eukaryotes and a regulator of the urea cycle in vertebrates. In vertebrates, N-acetylglutamic acid is the allosteric activator molecule to mitochondrial carbamyl phosphate synthetase I (CPSI) which is the first enzyme in the urea cycle. It triggers the production of the first urea cycle intermediate, a compound known as carbamyl phosphate. Notably the CPSI enzyme is inactive when N-acetylglutamic acid is not present. A deficiency in N-acetyl glutamate synthase or a genetic mutation in the gene coding for the enzyme will lead to urea cycle failure in which ammonia is not converted to urea, but rather accumulated in the blood leading to the condition called Type I hyperammonemia. Excessive amounts N-acetyl amino acids can be detected in the urine with individuals with aminoacylase I deficiency, a genetic disorder (PMID: 16465618). These include N-acetylalanine (as well as N-acetylserine, N-acetylglutamine, N-acetylglutamate, N-acetylglycine, N-acetylmethionine and smaller amounts of N-acetylthreonine, N-acetylleucine, N-acetylvaline and N-acetylisoleucine. Aminoacylase I is a soluble homodimeric zinc binding enzyme that catalyzes the formation of free aliphatic amino acids from N-acetylated precursors. In humans, Aminoacylase I is encoded by the aminoacylase 1 gene (ACY1) on chromosome 3p21 that consists of 15 exons (OMIM 609924). Individuals with aminoacylase I deficiency w... N-acetyl-l-glutamate, also known as L-N-acetylglutamic acid or ac-glu-oh, belongs to glutamic acid and derivatives class of compounds. Those are compounds containing glutamic acid or a derivative thereof resulting from reaction of glutamic acid at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-acetyl-l-glutamate is soluble (in water) and a weakly acidic compound (based on its pKa). N-acetyl-l-glutamate can be found in a number of food items such as cardoon, almond, butternut squash, and avocado, which makes N-acetyl-l-glutamate a potential biomarker for the consumption of these food products. N-acetyl-l-glutamate may be a unique S.cerevisiae (yeast) metabolite. Acquisition and generation of the data is financially supported in part by CREST/JST.

N-Acetylleucine

C8H15NO3 (173.105188)

N-Acetyl-L-leucine or N-Acetylleucine, belongs to the class of organic compounds known as N-acyl-alpha amino acids.

In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free leucine can also occur. In particular, N-Acetylleucine can be biosynthesized from L-leucine and acetyl-CoA by the enzyme leucine N-acetyltransferase (EC 2.3.1.66). Excessive amounts N-acetyl amino acids including N-acetylleucine (as well as N-acetylglycine, N-acetylserine, N-acetylglutamine, N-acetylglutamate, N-acetylalanine, N-acetylmethionine and smaller amounts of N-acetylthreonine, N-acetylisoleucine, and N-acetylvaline) can be detected in the urine with individuals with acylase I deficiency, a genetic disorder (PMID: 16465618).

In humans, Aminoacylase I is encoded by the aminoacylase 1 gene (ACY1) on chromosome 3p21 that consists of 15 exons (OMIM 609924). Individuals with aminoacylase I deficiency will experience convulsions, hearing loss and difficulty feeding (PMID: 16465618). ACY1 can also catalyze the reverse reaction, the synthesis of acetylated amino acids. Many N-acetylamino acids, including N-acetylleucine are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759).

N-Acetylputrescine

C6H14N2O (130.1106074)

N-Acetylputrescine is a polyamine commonly occurring excreted in normal human urine (PMID 7775374). N-Acetylputrescine is the most abundant of all polyamines both in normal individuals and in patients with leukemia (PMID 9464484). N-Acetylputrescine is the N-acetylated form of the naturally occurring polyamine called putrescine. The N-acetylation is mediated by the enzyme diamine N-acetyltransferase. Putrescine is related to cadaverine (another polyamine). Both are produced by the breakdown of amino acids in living and dead organisms and both are toxic in large doses. Putrescine and cadaverine are largely responsible for the foul odor of putrefying flesh, but also contribute to the odor of such processes as bad breath and bacterial vaginosis. Putrescine is also found in semen. Putrescine attacks s-adenosyl methionine and converts it to spermidine. Spermidine in turn attacks another s-adenosyl methionine and converts it to spermine. Putrescine is synthesized in small quantities by healthy living cells by the action of ornithine decarboxylase. N-Acetylputrescine can be found in Corynebacterium as well (PMID:25919117).

Nicotinuric acid

C8H8N2O3 (180.0534898)

Nicotinuric acid is an acylglycine. Acylglycines are normally minor metabolites of fatty acids. However, the excretion of certain acylglycines is increased in several inborn errors of metabolism. In certain cases, the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acylglycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction acyl-CoA + glycine <-> CoA + N-acylglycine. Nicotinuric acid is the major detoxification product of nicotinic acid. It may serve as a simple quantitative index of hepatic biotransformation of nicotinic acid (PMID:3243933). Nicotinuric acid is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism.

Nicotinuric acid is a metabolite of nicotinic acid.

Orotic acid

C5H4N2O4 (156.0171064)

Orotic acid is classified as a pyrimidinemonocarboxylic acid. That is it is a uracil bearing a carboxy substituent at position C-6. It is also classified as a pyrimidinedione and a carboxylic acid. Orotic acid is a minor dietary constituent. Indeed, until it was realized that it could be synthesized by humans, orotic acid was known as vitamin B-13. The richest dietary sources of orotic acid are cows milk and other dairy products as well as root vegetables such as carrots and beets. Dietary intake probably contributes to a basal rate of orotic acid excretion in urine because fasting decreases excretion by ~50\\\\%. However, it is now apparent that most urinary orotic acid is synthesized in the body, where it arises as an intermediate in the pathway for the synthesis of pyrimidine nucleotides. Orotic acid is converted to UMP by UMP synthase, a multifunctional protein with both orotate phosphoribosyltransferase and orotidylate decarboxylase activity. The most frequently observed inborn error of pyrimidine nucleotide synthesis is a mutation of the multifunctional protein UMP synthase (UMP synthase deficiency or orotic aciduria). This disorder prevents the conversion of orotic acid to UMP, and thus to other pyrimidines. As a result, plasma orotic acid accumulates to high concentrations, and increased quantities appear in the urine. Indeed, urinary orotic acid is so markedly increased in individuals harboring a mutation in UMP synthase that orotic acid crystals can form in the urine. The urinary concentration of orotic acid in individuals suffering from orotic aciduria can be of the order of millimoles of orotic acid per millimole creatinine. By comparison, the urinary level in unaffected individuals is ~ 1 ¬umol/mmol creatinine (PMID: 17513443). Orotic aciduria is characterized by megaloblastic anemia and orotic acid crystalluria that is frequently associated with some degree of physical and mental retardation. These features respond to appropriate pyrimidine replacement therapy and most cases appear to have a good prognosis. When present in sufficiently high levels, orotic acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of orotic acid are associated with at least seven inborn errors of metabolism, including argininemia, LPI syndrome (lysinuric protein intolerance), hyperornithinemia-hyperammonemia-homocitrullinuria (HHH), OTC deficiency, citrullinemia type I, purine nucleoside phosphorylase deficiency, and orotic aciduria. Orotic acid is broadly classified as an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. Orotic acid, also known as orotate or orotsaeure, is a member of the class of compounds known as pyrimidinecarboxylic acids. Pyrimidinecarboxylic acids are pyrimidines with a structure containing a carboxyl group attached to the pyrimidine ring. Orotic acid is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Orotic acid can be synthesized from uracil. Orotic acid can also be synthesized into dihydroorotic acid. Orotic acid can be found in a number of food items such as okra, atlantic herring, black chokeberry, and prunus (cherry, plum), which makes orotic acid a potential biomarker for the consumption of these food products. Orotic acid can be found primarily in most biofluids, including saliva, amniotic fluid, blood, and urine, as well as in human liver and pancreas tissues. Orotic acid exists in all living species, ranging from bacteria to humans. In humans, orotic acid is involved in the pyrimidine metabolism. Orotic acid is also involved in few metabolic disorders, which include beta ureidopropionase deficiency, dihydropyrimidinase deficiency, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and UMP synthase deficiency (orotic aciduria). Moreover, orotic acid is found to be associated with hyperornithinemia-hyperammonemia-homocitrullinuria, orotic aciduria I, ornithine transcarbamylase deficiency, and n-acetylglutamate synthetase deficiency. Orotic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. The compound is manufactured in the body via a mitochondrial enzyme, dihydroorotate dehydrogenase or a cytoplasmic enzyme of pyrimidine synthesis pathway. It is sometimes used as a mineral carrier in some dietary supplements (to increase their bioavailability), most commonly for lithium orotate . Chronically high levels of orotic acid are associated with at least 4 inborn errors of metabolism including: Argininemia, Citrullinemia Type I, Purine nucleoside phosphorylase deficiency and Orotic Aciduria (T3DB). Orotic acid (6-Carboxyuracil), a precursor in biosynthesis of pyrimidine nucleotides and RNA, is released from the mitochondrial dihydroorotate dehydrogenase (DHODH) for conversion to UMP by the cytoplasmic UMP synthase enzyme. Orotic acid is a marker for measurement in routine newborn screening for urea cycle disorders. Orotic acid can induce hepatic steatosis and hepatomegaly in rats[1][2][3].

Picolinic acid

C6H5NO2 (123.032027)

Picolinic acid is a metabolite of the tryptophan catabolism. Picolinic acid is produced under inflammatory conditions and a costimulus with interferon-gamma (IFNgamma) of macrophage (Mphi) effector functions, is a selective inducer of the Mphi inflammatory protein-1alpha (MIP-1alpha) and -1beta (MIPs), two chemokines/cytokines involved in the elicitation of the inflammatory reactions and in the development of the Th1 responses. IFNgamma and picolinic acid have reciprocal effects on the production of MIPs chemokines and the expression of their receptor. The concerted action of IFNgamma and picolinic acid on MIP-1alpha/beta chemokine/receptor system is likely to be of pathophysiological significance and to represent an important regulatory mechanism for leukocyte recruitment and distribution into damaged tissues during inflammatory responses. Picolinic acid has an effect on the production of L-arginine-derived reactive nitrogen intermediates in macrophages, by augmenting IFN-gamma-induced NO2- production, and acts synergistically with IFN-gamma in activating macrophages. Children with acrodermatitis enteropathica (AE) are treated with oral zinc dipicolinate (zinc-PA). The concentration of picolinic acid in the plasma of asymptomatic children with AE was significantly less than that of normal children. However, oral treatment with PA alone is ineffective. The results support the hypothesis that the genetic defect in AE is in the tryptophan pathway, although the role of PA in zinc metabolism remains to be defined. (PMID:15206716, 8473748, 1701787, 6694049). Picolinic acid is a metabolite of the tryptophan catabolism.

Purine

C5H4N4 (120.04359439999999)

Purine, also known as purine base or 1H-purine, belongs to the class of organic compounds known as purines and purine derivatives. These are aromatic heterocyclic compounds containing a purine moiety, which is formed a pyrimidine-ring ring fused to an imidazole ring. Two of the bases in nucleic acids, adenine and guanine, are purines. Purines from food (or from tissue turnover) are metabolised by several enzymes, including xanthine oxidase, into uric acid. Purine exists in all living species, ranging from bacteria to humans. High levels of uric acid can predispose to gout when the acid crystalises in joints; this phenomenon only happens in humans and some animal species (e.g. dogs) that lack an intrinsic uricase enzyme that can further degrade uric acid. In humans, purine is involved in thioguanine action pathway. Outside of the human body, purine is found, on average, in the highest concentration within cocoa beans. Purine has also been detected, but not quantified in several different foods, such as rapinis, plains prickly pears, blackcurrants, radish, and parsley. This could make purine a potential biomarker for the consumption of these foods. Purine is a heterocyclic aromatic organic compound, consisting of a pyrimidine ring fused to an imidazole ring. A purine is a heterocyclic aromatic organic compound, consisting of a pyrimidine ring fused to an imidazole ring.

Pyridoxamine

C8H12N2O2 (168.0898732)

Pyridoxamine is one form of vitamin B6. Chemically it is based on a pyridine ring structure, with hydroxyl, methyl, aminomethyl, and hydroxymethyl substituents. It differs from pyridoxine by the substituent at the 4-position. The hydroxyl at position 3 and aminomethyl group at position 4 of its ring endow pyridoxamine with a variety of chemical properties, including the scavenging of free radical species and carbonyl species formed in sugar and lipid degradation and chelation of metal ions that catalyze Amadori reactions. Pyridoxamine, also known as PM, belongs to the class of organic compounds known as pyridoxamine 5-phosphates. These are heterocyclic aromatic compounds containing a pyridoxamine that carries a phosphate group at the 5-position. Within humans, pyridoxamine participates in a number of enzymatic reactions. In particular, pyridoxamine can be converted into pyridoxal; which is mediated by the enzyme pyridoxine-5-phosphate oxidase. In addition, pyridoxamine can be converted into pyridoxamine 5-phosphate; which is catalyzed by the enzyme pyridoxal kinase. Pyridoxamine also inhibits the formation of advanced lipoxidation endproducts during lipid peroxidation reactions by reaction with dicarbonyl intermediates. In humans, pyridoxamine is involved in vitamin B6 metabolism. Outside of the human body, pyridoxamine has been detected, but not quantified in several different foods, such as nutmegs, sparkleberries, fennels, turmerics, and swiss chards. Pyridoxamine inhibits the Maillard reaction and can block the formation of advanced glycation endproducts, which are associated with medical complications of diabetes. Pyridoxamine is hypothesized to trap intermediates in the formation of Amadori products released from glycated proteins, possibly preventing the breakdown of glycated proteins by disrupting the catalysis of this process through disruptive interactions with the metal ions crucial to the redox reaction. One research study found that pyridoxamine specifically reacts with the carbonyl group in Amadori products, but inhibition of post-Amadori reactions (that can lead to advanced glycation endproducts) is due in much greater part to the metal chelation effects of pyridoxamine. The 4-aminomethyl form of vitamin B6.

Pyridoxine

C8H11NO3 (169.0738896)

Pyridoxine, also known vitamin B6, is commonly found in food and is used as a dietary supplement. Pyridoxine is an essential nutrient, meaning the body cannot synthesize it, and it must be obtained from the diet. Sources in the diet include fruit, vegetables, and grain. Although pyridoxine and vitamin B6 are still frequently used as synonyms, especially by medical researchers, this practice is sometimes misleading (PMID: 2192605). Technically, pyridoxine is one of the compounds that can be called vitamin B6 or it is a member of the family of B6 vitamins. Healthy human blood levels of pyridoxine are 2.1 - 21.7 ng/mL. Pyridoxine is readily converted to pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids and aminolevulinic acid. Pyridoxine assists in the balancing of sodium and potassium as well as promoting red blood cell production. Therefore pyridoxine is required by the body to make amino acids, carbohydrates, and lipids. It is linked to cancer immunity and helps fight the formation of homocysteine. It has been suggested that pyridoxine might help children with learning difficulties, and may also prevent dandruff, eczema, and psoriasis. In addition, pyridoxine can help balance hormonal changes in women and aid in immune system. Lack of pyridoxine may cause anemia, nerve damage, seizures, skin problems, and sores in the mouth (Wikipedia). Deficiency of pyridoxine, though rare because of widespread distribution in foods, leads to the development of peripheral neuritis in adults and affects the central nervous system in children (DOSE - 3rd edition). As a supplement pyridoxine is used to treat and prevent pyridoxine deficiency, sideroblastic anaemia, pyridoxine-dependent epilepsy, certain metabolic disorders, problems from isoniazid, and certain types of mushroom poisoning. Pyridoxine in combination with doxylamine is used as a treatment for morning sickness in pregnant women. Found in rice husks, cane molasses, yeast, wheat germ and cod liver oils. Vitamin, dietary supplement, nutrient. Pyridoxine is one of the compounds that can be called vitamin B6, along with pyridoxal and pyridoxamine.

Pyrrole-2-carboxylic acid

C5H5NO2 (111.032027)

Pyrrole-2-carboxylic acid was synthesized over a century ago, but its history as a compound of biological origin is rather recent. It was first identified as a degradation product of sialic acids, then as a derivative of the oxidation of the D-hydroxyproline isomers by mammalian D-amino acid oxidase. The latter relationship results from the lability of the direct oxidation product, A-pyrroline-4-hydroxy-2-carboxylic acid, which loses water spontaneously to form the pyrrole. A similar reaction is catalyzed by the more specific allohydroxy-D-proline oxidase of Pseudomonas. In whole animal observations, pyrrole-2-carboxylate (PCA) was identified in rat or human urine after administration of the D-isomers of hydroxyproline, a finding ascribable to the action of D-amino acid oxidase.

Riboflavin (Vitamin B2)

C17H20N4O6 (376.138278)

Riboflavin or vitamin B2 is an easily absorbed, water-soluble micronutrient with a key role in maintaining human health. Like the other B vitamins, it supports energy production by aiding in the metabolizing of fats, carbohydrates, and proteins.

Spermine

C10H26N4 (202.2157356)

Spermine, also known as gerontine or musculamine, belongs to the class of organic compounds known as dialkylamines. These are organic compounds containing a dialkylamine group, characterized by two alkyl groups bonded to the amino nitrogen. The resultin N-carbamoylputrescine is acted on by a hydrolase to split off urea group, leaving putrescine. The precursor for synthesis of spermine is the amino acid ornithine. The intermediate is spermidine. Spermine is a drug. Spermine exists in all living species, ranging from bacteria to humans. 5-methylthioadenosine and spermine can be biosynthesized from S-adenosylmethioninamine and spermidine through its interaction with the enzyme spermine synthase. Another pathway in plants starts with decarboxylation of L-arginine to produce agmatine. In humans, spermine is involved in spermidine and spermine biosynthesis. Outside of the human body, spermine is found, on average, in the highest concentration in oats. Spermine has also been detected, but not quantified in several different foods, such as sapodilla, mexican groundcherries, cloves, sourdocks, and sunflowers. This could make spermine a potential biomarker for the consumption of these foods. This decarboxylation gives putrescine. The name spermin was first used by the German chemists Ladenburg and Abel in 1888, and the correct structure of spermine was not finally established until 1926, simultaneously in England (by Dudley, Rosenheim, and Starling) and Germany (by Wrede et al.). In one pathway L-glutamine is the precursor to L-ornithine, after which the synthesis of spermine from L-ornithine follows the same pathway as in animals. Spermine is a potentially toxic compound.

Adipic acid

C6H10O4 (146.057906)

Adipic acid is an important inudstrial dicarboxylic acid with about 2.5 billion kilograms produced per year. It is used mainly in the production of nylon. It occurs relatively rarely in nature. It has a tart taste and is also used as an additive and gelling agent in jello or gelatins. It is also used in some calcium carbonate antacids to make them tart. Adipic acid has also been incorporated into controlled-release formulation matrix tablets to obtain pH-independent release for both weakly basic and weakly acidic drugs. Adipic acid in the urine and in the blood is typically exogenous in origin and is a good biomarker of jello consumption. In fact, a condition known as adipic aciduria is actually an artifact of jello consumption (PMID: 1779643). However, certain disorders (such as diabetes and glutaric aciduria type I.) can lead to elevated levels of adipic acid snd other dicarboxcylic acids (such as suberic acid) in urine (PMID: 17520433; PMID: 6778884). Moreover, adipic acid is also found to be associated with 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, carnitine-acylcarnitine translocase deficiency, malonyl-Coa decarboxylase deficiency, and medium Chain acyl-CoA dehydrogenase deficiency, which are inborn errors of metabolism.

Xanthurenic acid

C10H7NO4 (205.0375062)

Xanthurenic acid, also known as xanthurenate or 8-hydroxykynurenic acid, is a member of the class of compounds known as quinoline carboxylic acids. Quinoline carboxylic acids are quinolines in which the quinoline ring system is substituted by a carboxyl group at one or more positions. Xanthurenic acid is slightly soluble (in water). Xanthurenic acid can be found primarily in blood, feces, and urine, as well as in human epidermis tissue. Within the cell, xanthurenic acid is primarily located in the membrane. Xanthurenic acid exists in all eukaryotes, ranging from yeast to humans. In humans, xanthurenic acid is involved in the tryptophan metabolism. Moreover, xanthurenic acid is found to be associated with citrullinemia type I, which is an inborn error of metabolism. Xanthurenic acid is a metabolite from tryptophan catabolism. It is a substrate of the enzyme methyltransferases (EC 2.1.1.-) in pathway tryptophan metabolism (KEGG). Xanthurenic acid is a metabolite from tryptophan catabolism.

N-Acetyltryptophan

C13H14N2O3 (246.1004374)

N-Acetyl-L-tryptophan or N-Acetyltryptophan, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetyltryptophan can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetyltryptophan is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-tryptophan. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\\\% of all human proteins and 68\\\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetyltryptophan can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free tryptophan can also occur. Many N-acetylamino acids, including N-acetyltryptophan are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). N-Acetyltryptophan has also been used as a protein stabilizer. It prevents protein molecules from oxidative degradation by scavenging oxygen dissolved in protein solutions (PMID: 21903216 ). N-Acetyltryptophan has been identified as a catabolite of tryptophan generated by the gut microbiota. After absorption through the intestinal epithelium, tryptophan catabolites enter the bloodstream and are later excreted in the urine (PMID: 28916042). N-Acetyltryptophan is an inhibitor of cytochrome c release and an antagonist of the neurokinin 1 receptor (NK-1R). These inhibitory effects are thought have a useful role in neuroprotection. For instance, in mouse models of amyotrophic lateral sclerosis (ALS) the administration of N-Acetyltryptophan has been shown delay disease onset, extend survival, and ameliorate deterioration in motor performance ALS transgenic mice (PMID: 25986728). N-acetyltryptophan has been shown to significantly reduce blood-brain barrier permeability and improve functional outcome in rat models of traumatic brain injury (PMID: 29256408). N-Acetyltryptophan has also been shown to have a role in preventing hepatic ischemia-reperfusion injury. This is thought to occur through de-activation of the RIP2/caspase/IL-1beta signaling pathway (PMID: 31184936).

Deoxyinosine

C10H12N4O4 (252.08585119999998)

Deoxyinosine is a nucleoside that is formed when hypoxanthine is attached to a deoxyribose ring (also known as a ribofuranose) via a beta-N9-glycosidic bond. Deoxyinosine is found in DNA while inosine is found in RNA. Inosine is a nucleic acid important for RNA editing. Adenosine deaminase (ADA) catalyzes the conversion of adenosine and deoxyadenosine to inosine and deoxyinosine, respectively. ADA-deficient individuals suffer from severe combined immunodeficiency (SCID) and are unable to produce significant numbers of mature T or B lymphocytes. This occurs as a consequence of the accumulation of ADA substrates or their metabolites. Inosine is also an intermediate in a chain of purine nucleotides reactions required for muscle movements. Moreover, deoxyinosine is found to be associated with purine nucleoside phosphorylase (PNP) deficiency, which is an inborn error of metabolism.

Gluconic acid

C6H12O7 (196.0583002)

Gluconic acid, also known as D-gluconic acid, D-gluconate or (2R,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanoic acid (also named dextronic acid), is the C1-oxidized form of D-glucose where the aldehyde group has become oxidized to the corresponding carboxylic acid. Gluconic acid belongs to the class of organic compounds known as sugar acids and derivatives. Sugar acids and derivatives are compounds containing a saccharide unit which bears a carboxylic acid group. In aqueous solution, gluconic acid exists in equilibrium with the cyclic ester glucono delta-lactone. Gluconic acid occurs naturally in fruit, honey, kombucha tea and wine. The salts of gluconic acid are known as "gluconates". Gluconic acid, gluconate salts, and gluconate esters occur widely in nature because such species arise from the oxidation of glucose. Gluconic acid exists in all living species, ranging from bacteria to plants to humans. The metabolism of gluconate is well characterized in prokaryotes where it is known to be degraded following phosphorylation by gluconokinase. Glucokinase activity has also been detected in mammals, including humans (PMID: 24896608). Gluconic acid is produced in the gluconate shunt pathway. In the gluconate shunt, glucose is oxidized by glucose dehydrogenase (also called glucose oxidase) to furnish gluconate, the form in which D-gluconic acid is present at physiological pH. Subsequently, gluconate is phosphorylated by the action of gluconate kinase to produce 6-phosphogluconate, which is the second intermediate of the pentose phosphate pathway. This gluconate shunt is mainly found in plants, algae, cyanobacteria and some bacteria, which all use the Entner–Doudoroff pathway to degrade glucose or gluconate; this generates 2-keto-3-deoxygluconate-6-phosphate, which is then cleaved to generate pyruvate and glyceraldehyde 3-phosphate. Glucose dehydrogenase and gluconate kinase activities are also present in mammals, fission yeast, and flies. Gluconic acid has many industrial uses. It is used as a drug as part of electrolyte supplementation in total parenteral nutrition. It is also used in cleaning products where it helps cleaning up mineral deposits. Gluconic acid or Gluconic acid is used to maintain the cation-anion balance on electrolyte solutions. In humans, gluconic acid is involved in the metabolic disorder called the transaldolase deficiency. Gluconic acid has been found to be a metabolite in Aspergillus (Hugo Vanden Bossche, D.W.R. Mackenzie and G. Cauwenbergh. Aspergillus and Aspergillosis, 1987).

Glutaric acid

C5H8O4 (132.0422568)

Glutaric acid is a simple five-carbon linear dicarboxylic acid. Glutaric acid is naturally produced in the body during the metabolism of some amino acids, including lysine and tryptophan. Glutaric acid may cause irritation to the skin and eyes. When present in sufficiently high levels, glutaric acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of glutaric acid are associated with at least three inborn errors of metabolism, including glutaric aciduria type I, malonyl-CoA decarboxylase deficiency, and glutaric aciduria type III. Glutaric aciduria type I (glutaric acidemia type I, glutaryl-CoA dehydrogenase deficiency, GA1, or GAT1) is an inherited disorder in which the body is unable to completely break down the amino acids lysine, hydroxylysine, and tryptophan due to a deficiency of mitochondrial glutaryl-CoA dehydrogenase (EC 1.3.99.7, GCDH). Excessive levels of their intermediate breakdown products (e.g. glutaric acid, glutaryl-CoA, 3-hydroxyglutaric acid, glutaconic acid) can accumulate and cause damage to the brain (and also other organs). Babies with glutaric acidemia type I are often born with unusually large heads (macrocephaly). Macrocephaly is amongst the earliest signs of GA1. GA1 also causes secondary carnitine deficiency because glutaric acid, like other organic acids, is detoxified by carnitine. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of untreated glutaric aciduria. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. Treatment of glutaric aciduria is mainly based on the restriction of lysine intake, supplementation of carnitine, and an intensification of therapy during intercurrent illnesses. The major principle of dietary treatment is to reduce the production of glutaric acid and 3-hydroxyglutaric acid by restriction of natural protein, in general, and of lysine, in particular (PMID: 17465389, 15505398). Glutaric acid has also been found in Escherichia (PMID: 30143200). Isolated from basidiomycete fungi and fruits of Prunus cerasus (CCD). Glutaric acid is found in many foods, some of which are red beetroot, common beet, soy bean, and tamarind. Glutaric acid, C5 dicarboxylic acid, is an intermediate during the catabolic pathways of lysine and tryptophan. Glutaric acid affects pericyte contractility and migration. Glutaric acid is an indicator of glutaric aciduria type I[1][2][3]. Glutaric acid, C5 dicarboxylic acid, is an intermediate during the catabolic pathways of lysine and tryptophan.

Uridine diphosphate glucose

C15H24N2O17P2 (566.0550194)

Uridine diphosphate glucose, also known as UDP-glucose or UDP-alpha-D-glucose, belongs to the class of organic compounds known as pyrimidine nucleotide sugars. These are pyrimidine nucleotides bound to a saccharide derivative through the terminal phosphate group. Uridine diphosphate glucose exists in all living species, ranging from bacteria to plants to humans. Uridine diphosphate glucose is a key intermediate in carbohydrate metabolism. For instance, UDP-glucose is a precursor of glycogen and can be converted into UDP-galactose and UDP-glucuronic acid, which can then be used as substrates by the enzymes that make polysaccharides containing galactose and glucuronic acid. UDP-glucose can also be used as a precursor for the biosynthesis of sucrose, lipopolysaccharides and glycosphingolipids. Within humans, uridine diphosphate glucose participates in a number of enzymatic reactions. In particular, ceramide (D18:1/18:0) and uridine diphosphate glucose can be converted into glucosylceramide (D18:1/18:0) and uridine 5-diphosphate through the action of the enzyme ceramide glucosyltransferase. In addition, glucosylceramide (D18:1/18:0) and uridine diphosphate glucose can be biosynthesized from lactosylceramide (D18:1/18:0) and uridine 5-diphosphate through its interaction with the enzyme Beta-1,4-galactosyltransferase 6.

Syringic acid

C9H10O5 (198.052821)

Syringic acid, also known as syringate or cedar acid, belongs to the class of organic compounds known as gallic acid and derivatives. Gallic acid and derivatives are compounds containing a 3,4,5-trihydroxybenzoic acid moiety. Outside of the human body, Syringic acid is found, on average, in the highest concentration within a few different foods, such as common walnuts, swiss chards, and olives and in a lower concentration in apples, tarragons, and peanuts. Syringic acid has also been detected, but not quantified in several different foods, such as sweet marjorams, silver lindens, bulgurs, annual wild rices, and barley. This could make syringic acid a potential biomarker for the consumption of these foods. Syringic acid is correlated with high antioxidant activity and inhibition of LDL oxidation.

Homogentisic acid

C8H8O4 (168.0422568)

Homogentisic acid, also known as melanic acid, is an intermediate in the breakdown or catabolism of tyrosine and phenylalanine. It is generated from the compound p-hydroxyphenylpyruvate through the enzyme p-hydroxyphenylpyruvate dehydrogenase. The resulting homogentisic acid is then broken down into 4-maleylacetoacetate via the enzyme homogentisate 1,2-dioxygenase. Homogentisic acid is also found in other organisms. For instance, it can found in Arbutus unedo (strawberry-tree) honey, in the bacterial plant pathogen Xanthomonas campestris as well as in the yeast Yarrowia lipolytica where it is associated with the production of brown pigments. Homogentisic acid can be oxidatively dimerized to form hipposudoric acid, one of the main constituents of the blood sweat of hippopotamuses. When present in sufficiently high levels, homogentisic acid can function as an osteotoxin and a renal toxin. An osteotoxin is a substance that causes damage to bones and/or joints. A renal toxin causes damage to the kidneys. Chronically high levels of homogentisic acid are associated with alkaptonuria (OMIM: 203500), an inborn error of metabolism. Alkaptonuria is a rare inherited genetic disorder in which the body cannot process the amino acids phenylalanine and tyrosine. It is caused by a mutation in the enzyme homogentisate 1,2-dioxygenase (EC 1.13.11.5), which leads to an accumulation of homogentisic acid in the blood and tissues. Homogentisic acid and its oxidized form benzoquinone acetic acid are excreted in the urine, giving it an unusually dark color. The accumulating homogentisic acid (and benzoquinone acetic acid) causes damage to cartilage (ochronosis, leading to osteoarthritis) and heart valves as well as precipitating as kidney stones and stones in other organs. More specifically, homogentisic acid can be converted to benzoquinone acetic acid (BQA), and the resulting BQA can be readily converted to polymers that resemble the dark skin pigment melanin. These polymers are deposited in the collagen, a connective tissue protein, of particular tissues such as cartilage. This process is called ochronosis (as the tissue looks ochre); ochronotic tissue is stiffened and unusually brittle, impairing its normal function and causing damage. Homogentisic acid is the primary precursor of melanin synthesis in Vibrio cholerae. 2-(3,6-dihydroxyphenyl)acetic acid, also known as homogentisic acid or homogentisate, is a member of the class of compounds known as 2(hydroxyphenyl)acetic acids. 2(hydroxyphenyl)acetic acids are phenylacetic acids that carry a hydroxyl group at the 2-position. 2-(3,6-dihydroxyphenyl)acetic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 2-(3,6-dihydroxyphenyl)acetic acid can be found in a number of food items such as gooseberry, angelica, chinese broccoli, and cucumber, which makes 2-(3,6-dihydroxyphenyl)acetic acid a potential biomarker for the consumption of these food products. 2-(3,6-dihydroxyphenyl)acetic acid can be found primarily in blood, feces, and urine, as well as in human cartilage, connective tissue and kidney tissues. In humans, 2-(3,6-dihydroxyphenyl)acetic acid is involved in few metabolic pathways, which include disulfiram action pathway, phenylalanine and tyrosine metabolism, and tyrosine metabolism. 2-(3,6-dihydroxyphenyl)acetic acid is also involved in several metabolic disorders, some of which include dopamine beta-hydroxylase deficiency, tyrosinemia type 3 (TYRO3), alkaptonuria, and tyrosinemia type 2 (or richner-hanhart syndrome). Moreover, 2-(3,6-dihydroxyphenyl)acetic acid is found to be associated with alkaptonuria. 2-(3,6-dihydroxyphenyl)acetic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Apart from treatment of the complications (such as pain relief using NSAIDs and joint replacement for the cartilage damage), vitamin C has been used to reduce the ochronosis and lowering of the homogentisic acid levels may be attempted with a low-protein diet. Recently the drug nitisinone has been found to suppress homogentisic acid production. Nitrisinone inhibits the enzyme, 4-hydroxyphenylpyruvate dioxygenase, responsible for converting tyrosine to homogentisic acid, thereby blocking the production and accumulation of homogentisic acid. Nitisinone treatment has been shown to cause a 95\\\\% reduction in plasma and urinary homogentisic acid (T3DB). Acquisition and generation of the data is financially supported in part by CREST/JST.

Hydrocinnamic acid

C9H10O2 (150.068076)

Hydrocinnamic acid, also known as 3-phenylpropanoic acid or dihydrocinnamic acid, belongs to the class of organic compounds known as phenylpropanoic acids. Phenylpropanoic acids are compounds with a structure containing a benzene ring conjugated to a propanoic acid (C6-C3). Phenylpropanoic acid can be prepared from cinnamic acid by hydrogenation. Hydrocinnamic acid is a sweet, balsamic, and cinnamon tasting compound. This compound is used frequently in cosmetic products such as perfumes, bath gels, detergent powders, liquid detergents, fabric softeners, and soaps as it gives off a floral scent. A characteristic reaction of phenylpropanoic acid is its cyclization to indanones. Phenylpropanoic acid is used in the food industry to preserve and maintain the original aroma quality of frozen foods. Phenylpropanoic acid is also added to food for technological purposes in a wide variety including manufacturing, processing, preparation, treatment, packaging, transportation or storage, and food additives. This compound is used as a sweetener as well to sweeten food and can be found in tabletop sweeteners. Hydrocinnamic acid is an analogue of phenylalanine. It is a substrate of the enzyme oxidoreductases [EC 1.14.12.-] in the pathway phenylalanine metabolism (KEGG). 3-Phenylpropanoic acid is found in many foods, some of which are purple laver, quinoa, custard apple, and conch.

L-Cysteine

C3H7NO2S (121.0197482)

Cysteine (Cys), also known as L-cysteine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-alanine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Cysteine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, non-polar, sulfur-containing amino acid. Cysteine is an important source of sulfur in human metabolism, and although it is classified as a non-essential amino acid, cysteine may be essential for infants, the elderly, and individuals with certain metabolic disease or who suffer from malabsorption syndromes. Cysteine can occasionally be considered as an essential or conditionally essential amino acid. Cysteine is unique amongst the twenty natural amino acids as it contains a thiol group. Thiol groups can undergo oxidation/reduction (redox) reactions; when cysteine is oxidized it can form cystine, which is two cysteine residues joined by a disulfide bond. This reaction is reversible since the reduction of this disulphide bond regenerates two cysteine molecules. The disulphide bonds of cystine are crucial to defining the structures of many proteins. Cysteine is often involved in electron-transfer reactions, and help the enzyme catalyze its reaction. Cysteine is also part of the antioxidant glutathione. N-Acetyl-L-cysteine (NAC) is a form of cysteine where an acetyl group is attached to cysteines nitrogen atom and is sold as a dietary supplement. Cysteine is named after cystine, which comes from the Greek word kustis meaning bladder (cystine was first isolated from kidney stones). Oxidation of cysteine can produce a disulfide bond with another thiol and further oxidation can produce sulphfinic or sulfonic acids. The cysteine thiol group is also a nucleophile and can undergo addition and substitution reactions. Thiol groups become much more reactive when they are ionized, and cysteine residues in proteins have pKa values close to neutrality, so they are often in their reactive thiolate form in the cell. The thiol group also has a high affinity for heavy metals and proteins containing cysteine will bind metals such as mercury, lead, and cadmium tightly. Due to this ability to undergo redox reactions, cysteine has antioxidant properties. Cysteine is important in energy metabolism. As cystine, it is a structural component of many tissues and hormones. Cysteine has clinical uses ranging from treating baldness to psoriasis to preventing smokers hack. In some cases, oral cysteine therapy has proved excellent for treatment of asthmatics, enabling them to stop theophylline and other medications. Cysteine also enhances the effect of topically applied silver, tin, and zinc salts in preventing dental cavities. In the future, cysteine may play a role in the treatment of cobalt toxicity, diabetes, psychosis, cancer, and seizures (http://www.dcnutrition.com/AminoAcids/). Cysteine has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821).

Methylmalonic acid

C4H6O4 (118.0266076)

Methylmalonic acid is a malonic acid derivative, which is a vital intermediate in the metabolism of fat and protein. In particular, the coenzyme A-linked form of methylmalonic acid, methylmalonyl-CoA, is converted into succinyl-CoA by methylmalonyl-CoA mutase in a reaction that requires vitamin B12 as a cofactor. In this way, methylmalonic acid enters the Krebs cycle and is thus part of one of the anaplerotic reactions. Abnormalities in methylmalonic acid metabolism lead to methylmalonic aciduria. This inborn error of metabolism is attributed to a block in the enzymatic conversion of methylmalonyl CoA to succinyl CoA. Methylmalonic acid is also found to be associated with other inborn errors of metabolism, including cobalamin deficiency, cobalamin malabsorption, malonyl-CoA decarboxylase deficiency, and transcobalamin II deficiency. When present in sufficiently high levels, methylmalonic acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of methylmalonic acid are associated with at least 5 inborn errors of metabolism, including Malonyl CoA decarboxylase deficiency, Malonic Aciduria, Methylmalonate Semialdehyde Dehydrogenase Deficiency, Methylmalonic Aciduria and Methylmalonic Aciduria Due to Cobalamin-Related Disorders. Methylmalonic acid is an organic acid and abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart abnormalities, kidney abnormalities, liver damage, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures.

An amine derived by enzymatic decarboxylation of histidine. It is a powerful stimulant of gastric secretion, a constrictor of bronchial smooth muscle, a vasodilator, and also a centrally acting neurotransmitter.; Histamine is a biogenic amine involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter. Histamine triggers the inflammatory response. As part of an immune response to foreign pathogens, histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine increases the permeability of the capillaries to white blood cells and other proteins, in order to allow them to engage foreign invaders in the affected tissues. It is found in virtually all animal body cells.[citation needed]; Histamine is derived from the decarboxylation of the amino acid histidine, a reaction catalyzed by the enzyme L-histidine decarboxylase. It is a hydrophilic vasoactive amine. Histamine is an amine derived by enzymatic decarboxylation of histidine.

N-acetylaspartate (NAA)

C6H9NO5 (175.0480704)

N-Acetyl-L-Aspartic acid (NAA) or N-Acetylaspartic acid, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-alpha-Acetyl-L-aspartic acid can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetyl-L-aspartic acid is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-aspartic acid. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\% of all human proteins and 68\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetylaspartate can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free aspartic acid can also occur. In particular, N-Acetyl-L-aspartic acid can be synthesized in neurons from the amino acid aspartate and acetyl coenzyme A (acetyl CoA). Specifically, the enzyme known as aspartate N-acetyltransferase (EC 2.3.1.17) catalyzes the transfer of the acetyl group of acetyl CoA to the amino group of aspartate. N-Acetyl-L-aspartic acid is the second most concentrated molecule in the brain after the amino acid glutamate. The various functions served by N-acetylaspartic acid are still under investigation, but the primary proposed functions include (1) acting as a neuronal osmolyte that is involved in fluid balance in the brain, (2) serving as a source of acetate for lipid and myelin synthesis in oligodendrocytes (the glial cells that myelinate neuronal axons), (3) serving as a precursor for the synthesis of the important dipeptide neurotransmitter N-acetylaspartylglutamate (NAAG), and (4) playing a potential role in energy production from the amino acid glutamate in neuronal mitochondria. High neurotransmitter (i.e. N-acetylaspartic acid) levels can lead to abnormal neural signaling, delayed or arrested intellectual development, and difficulties with general motor skills. When present in sufficiently high levels, N-acetylaspartic acid can be a neurotoxin, an acidogen, and a metabotoxin. A neurotoxin is a compound that disrupts or attacks neural tissue. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of N-acetylaspartic acid are associated with Canavan disease. Because N-acetylaspartic acid functions as an organic acid and high levels of organic acids can lead to a condition known... N-Acetylaspartic acid is a derivative of aspartic acid. It is the second most concentrated molecule in the brain after the amino acid glutamate. It is synthesized in neurons from the amino acid aspartate and acetyl coenzyme A.

N-Acetyl-L-methionine or N-Acetylmethionine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetylmethionine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetylmethionine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-methionine.

In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free methionine can also occur. In particular, N-Acetylmethionine can be biosynthesized from L-methionine and acetyl-CoA by the enzyme methionine N-acetyltransferase (EC 2.3.1.66). Excessive amounts N-acetyl amino acids including N-acetylmethionine (as well as N-acetylglycine, N-acetylserine, N-acetylglutamine, N-acetylglutamate, N-acetylalanine, N-acetylleucine and smaller amounts of N-acetylthreonine, N-acetylisoleucine, and N-acetylvaline) can be detected in the urine with individuals with acylase I deficiency, a genetic disorder (PMID: 16465618). Aminoacylase I is a soluble homodimeric zinc binding enzyme that catalyzes the formation of free aliphatic amino acids from N-acetylated precursors. In humans, Aminoacylase I is encoded by the aminoacylase 1 gene (ACY1) on chromosome 3p21 that consists of 15 exons (OMIM 609924). Individuals with aminoacylase I deficiency will experience convulsions, hearing loss and difficulty feeding (PMID: 16465618). ACY1 can also catalyze the reverse reaction, the synthesis of acetylated amino acids. Many N-acetylamino acids, including N-acetylmethionine are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759).

Deoxyguanosine

C10H13N5O4 (267.09674980000005)

Deoxyguanosine, also known as dG, belongs to the class of organic compounds known as purine 2-deoxyribonucleosides. Purine 2-deoxyribonucleosides are compounds consisting of a purine linked to a ribose which lacks a hydroxyl group at position 2‚Äô. Deoxyguanosine is a nucleoside consisting of the base guanine and the sugar deoxyribose. Deoxyguanosine is one of the four deoxyribonucleosides that make up DNA. Deoxyguanosine exists in all living species, ranging from bacteria to plants to humans. Deoxyguanosine participates in a number of enzymatic reactions. In particular, deoxyguanosine can be biosynthesized from 2-deoxyguanosine 5-monophosphate through the enzyme known as cytosolic purine 5-nucleotidase. In addition, deoxyguanosine can be converted into 2-deoxyguanosine 5-monophosphate (dGMP); which is mediated by the enzyme deoxyguanosine kinase. Deoxyguanosine is involved in the rare, inherited metabolic disorder called the purine nucleoside phosphorylase deficiency (PNP deficiency). In particular PNP deficiency is characterized by elevated levels of dGTP (deoxyguanosine triphosphate). PNP accounts for approximately 4\\\\% of patients with severe combined immunodeficiency (PMID: 1931007).

Uridine 5'-monophosphate

C9H13N2O9P (324.03586580000007)

Uridine 5-monophosphate (UMP), also known as uridylic acid or uridylate, belongs to the class of organic compounds known as pyrimidine ribonucleoside monophosphates. These are pyrimidine ribobucleotides with monophosphate group linked to the ribose moiety. UMP consists of a phosphate group, a pentose sugar ribose, and the nucleobase uracil; hence, it is a ribonucleotide monophosphate. Uridine 5-monophosphate exists in all living species, ranging from bacteria to plants to humans. UMP is a nucleotide that is primarily used as a monomer in RNA biosynthesis. Uridine monophosphate is formed from Orotidine 5-monophosphate (orotidylic acid) in a decarboxylation reaction catalyzed by the enzyme orotidylate decarboxylase. Within humans, uridine 5-monophosphate participates in a number of enzymatic reactions. In particular, uridine 5-monophosphate can be converted into uridine 5-diphosphate through the action of the enzyme UMP-CMP kinase. In addition, uridine 5-monophosphate can be biosynthesized from uridine 5-diphosphate through its interaction with the enzyme soluble calcium-activated nucleotidase 1. In brain research studies, uridine monophosphate has been used as a convenient delivery compound for uridine. Uridine is present in many foods, mainly in the form of RNA. Non-phosphorylated uridine is not bioavailable beyond first-pass metabolism. In a study, gerbils fed a combination of uridine monophosphate, choline, and docosahexaenoic acid (DHA) were found to have significantly improved performance in running mazes over those not fed the supplements, implying an increase in cognitive function (PMID: 18606862). 5′-UMP.

Xanthosine

C10H12N4O6 (284.07568119999996)

Xanthosine, also known as xanthine riboside, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Xanthosine is a nucleoside derived from xanthine and ribose. Xanthosine exists in all living species, ranging from bacteria to plants to humans. In plants xanthosine is the biosynthetic precursor to 7-methylxanthosine which is produced by the action of the enzyme known as 7-methylxanthosine synthase. 7-Methylxanthosine in turn is the precursor to theobromine (the active alkaloid in chocolate), which in turn is the precursor to caffeine, the active alkaloid in coffee and tea. Within humans, xanthosine participates in a number of enzymatic reactions. In particular, xanthosine can be biosynthesized from xanthylic acid; which is catalyzed by the enzyme cytosolic purine 5-nucleotidase. In addition, xanthosine can be converted into xanthine and ribose 1-phosphate; which is mediated by the enzyme purine nucleoside phosphorylase. Xanthosine monophosphate (XMP) is an intermediate in purine metabolism, formed from IMP (inosine monophosphate).

Aldohexose 6-phosphate

C6H13O9P (260.0297178)

Phosphoethanolamine

C2H8NO4P (141.0190938)

O-Phosphoethanolamine, also known as PEA, phosphorylethanolamine, colamine phosphoric acid or ethanolamine O-phosphate, belongs to the class of organic compounds known as phosphoethanolamines. Phosphoethanolamines are compounds containing a phosphate linked to the second carbon of an ethanolamine. O-Phosphoethanolamine is used in the biosynthesis of two different types of phospholipids: glycerophospholipids and sphingolipids. O-Phosphoethanolamine exists in all living species, ranging from bacteria to plants to humans. Within humans, O-phosphoethanolamine participates in a number of enzymatic reactions. In particular, cytidine triphosphate and O-phosphoethanolamine can be converted into CDP-ethanolamine; which is mediated by the enzyme ethanolamine-phosphate cytidylyltransferase. In addition, O-phosphoethanolamine can be biosynthesized from ethanolamine; which is catalyzed by the enzyme choline/ethanolamine kinase. In humans, O-phosphoethanolamine is involved in phosphatidylcholine biosynthesis. O-phosphoethanolamine is also a product of the metabolism of sphingolipids. In particular, sphinglipids are metabolized in vivo to phosphorylethanolamine and a fatty aldehyde, generally palmitaldehyde. Both metabolites are ultimately converted to glycerophospholipids. The lipids are first phosphorylated by a kinase and then cleaved by the pyridoxal-dependent sphinganine-1-phosphate aldolase. Elevated urine levels of O-Phosphoethanolamine or PEA can be used to help in the diagnosis of Hypophosphatasia (HPP). Reference ranges for urinary PEA vary according to age and somewhat by diet, and follow a circadian rhythm. Outside of the human body, O-phosphoethanolamine has been detected, but not quantified in, several different foods, such as oxheart cabbages, anises, shiitakes, abalones, and teffs. Phosphoryl-ethanolamine, also known as colamine phosphoric acid or ethanolamine phosphate, is a member of the class of compounds known as phosphoethanolamines. Phosphoethanolamines are compounds containing a phosphate linked to the second carbon of an ethanolamine. Phosphoryl-ethanolamine is soluble (in water) and a moderately acidic compound (based on its pKa). Phosphoryl-ethanolamine can be found in a number of food items such as pepper (capsicum), black salsify, cascade huckleberry, and redcurrant, which makes phosphoryl-ethanolamine a potential biomarker for the consumption of these food products. Phosphoryl-ethanolamine can be found primarily in most biofluids, including cerebrospinal fluid (CSF), blood, saliva, and feces. Phosphoryl-ethanolamine exists in all living species, ranging from bacteria to humans. In humans, phosphoryl-ethanolamine is involved in several metabolic pathways, some of which include phosphatidylethanolamine biosynthesis PE(22:5(4Z,7Z,10Z,13Z,16Z)/22:5(4Z,7Z,10Z,13Z,16Z)), phosphatidylethanolamine biosynthesis PE(14:0/20:1(11Z)), phosphatidylethanolamine biosynthesis PE(20:2(11Z,14Z)/20:3(8Z,11Z,14Z)), and phosphatidylethanolamine biosynthesis PE(22:5(7Z,10Z,13Z,16Z,19Z)/16:1(9Z)). Phosphoryl-ethanolamine is also involved in few metabolic disorders, which include fabry disease, gaucher disease, and krabbe disease. Moreover, phosphoryl-ethanolamine is found to be associated with traumatic brain injury. Acquisition and generation of the data is financially supported in part by CREST/JST.

Nicotinamide adenine dinucleotide phosphate

C21H30N7O17P3 (745.0911)

NADPH is the reduced form of NADP+, and NADP+ is the oxidized form of NADPH. Nicotinamide adenine dinucleotide phosphate (NADP) is a coenzyme composed of ribosylnicotinamide 5-phosphate (NMN) coupled with a pyrophosphate linkage to 5-phosphate adenosine 2,5-bisphosphate. NADP serves as an electron carrier in a number of reactions, being alternately oxidized (NADP+) and reduced (NADPH). NADP is formed through the addition of a phosphate group to the 2 position of the adenosyl nucleotide through an ester linkage (Dorland, 27th ed). This extra phosphate is added by the enzyme NAD+ kinase and removed via NADP+ phosphatase. NADP is also known as TPN (triphosphopyridine nucleotide) and it is an important cofactor used in anabolic reactions in all forms of cellular life. Examples include the Calvin cycle, cholesterol synthesis, fatty acid elongation, and nucleic acid synthesis (Wikipedia). Nicotinamide adenine dinucleotide phosphate.

dIMP

C10H13N4O7P (332.0521838)

dIMP is a deoxyribonucleoside and is considered a derivative of the nucleoside inosine, differing from the latter by the replacement of a hydroxyl group (-OH) by hydrogen (-H) at the 2 position of its ribose sugar moiety. The hydrolytic deamination of dAMP residues in DNA yields dIMP residues. The deamination of adenine residues in DNA generates hypoxanthine, which is mutagenic since it can pair not only with thymine but also with cytosine and therefore would result in A-T to G-C transitions after DNA replication. Hypoxanthine DNA glycosylase (EC 3.2.2.15) excises hypoxanthine from DNA containing dIMP residues in mammalian cells.

Glucose 6-phosphate

C6H13O9P (260.0297178)

Glucose 6 phosphate (alpha-D-glucose 6 phosphate or G6P) is the alpha-anomer of glucose-6-phosphate. There are two anomers of glucose 6 phosphate, the alpha anomer and the beta anomer. Glucose 6 phosphate is an ester of glucose with phosphoric acid, made in the course of glucose metabolism by mammalian and other cells. It is a normal constituent of resting muscle and probably is in constant equilibrium with fructose-6-phosphate. (Stedman, 26th ed). Glucose-6-phosphate is a phosphorylated glucose molecule on carbon 6. When glucose enters a cell, it is immediately phosphorylated to G6P. This is catalyzed with hexokinase enzymes, thus consuming one ATP. A major reason for immediate phosphorylation of the glucose is so that it cannot diffuse out of the cell. The phosphorylation adds a charged group so the G6P cannot easily cross cell membranes. G6P can travel down two metabolic pathways, glycolysis and the pentose phosphate pathway. In addition to the metabolic pathways, G6P can also be stored as glycogen in the liver if blood glucose levels are high. If the body needs energy or carbon skeletons for syntheses, G6P can be isomerized to Fructose-6-phosphate and then phosphorylated to Fructose-1,6-bisphosphate. Note, the molecule now has 2 phosphoryl groups attached. The addition of the 2nd phosphoryl group is an irreversible step, so once this happens G6P will enter glycolysis and be turned into pyruvate (ATP production occurs). If blood glucose levels are high, the body needs a way to store the excess glucose. After being converted to G6P, phosphoglucose mutase (isomerase) can turn the molecule into glucose-1-phosphate. Glucose-1-phosphate can then be combined with uridine triphosphate (UTP) to form UDP-glucose. This reaction is driven by the hydrolysis of pyrophosphate that is released in the reaction. Now, the activated UDP-glucose can add to a growing glycogen molecule with the help of glycogen synthase. This is a very efficient storage mechanism for glucose since it costs the body only 1 ATP to store the 1 glucose molecule and virtually no energy to remove it from storage. It is important to note that glucose-6-phosphate is an allosteric activator of glycogen synthase, which makes sense because when the level of glucose is high the body should store the excess glucose as glycogen. On the other hand, glycogen synthase is inhibited when it is phosphorylated by protein kinase a during times of high stress or low blood glucose levels. -- Wikipedia [HMDB] Glucose 6-phosphate (G6P, sometimes called the Robison ester) is a glucose sugar phosphorylated at the hydroxy group on carbon 6.

α-D-Glucose-1-phosphate

C6H13O9P (260.0297178)

Glucose 1-phosphate (also called cori ester) is a glucose molecule with a phosphate group on the 1-carbon. It can exist in either the α- or β-anomeric form. Glucose 1-phosphate belongs to the class of organic compounds known as monosaccharide phosphates. These are monosaccharides comprising a phosphated group linked to the carbohydrate unit. Glucose 1-phosphate is the direct product of the reaction in which glycogen phosphorylase cleaves off a molecule of glucose from a greater glycogen structure. It cannot travel down many metabolic pathways and must be interconverted by the enzyme phosphoglucomutase in order to become glucose 6-phosphate. Free glucose 1-phosphate can also react with UTP to form UDP-glucose. It can then return to the greater glycogen structure via glycogen synthase. *Found widely in both plants and animals.

7-Methyladenine

C6H7N5 (149.07014220000002)

7-Methyladenine is part of the base excision repair pathway. In this pathway, alkylated DNA is hydrolysed via the enzyme DNA-3-methyladenine glycosylase II (EC 3.2.2.21), releasing 3-methyladenine, 3-methylguanine, 7-methylguanine and 7-methyladenine. This enzyme is responsible for the hydrolysis of the deoxyribose N-glycosidic bond to excise 3-methyladenine, and 7-methylguanine from the damaged DNA polymer formed by alkylation lesions. Base excision repair (BER) is a cellular mechanism that repairs damaged DNA throughout the cell cycle. Repairing DNA sequence errors is necessary so that mutations are not propagated or to remove lesions that may lead to breaks in the DNA during replication. Single bases in DNA can be chemically mutated, for example by deamination or alkylation, resulting in incorrect base-pairing, and consequently, mutations in the DNA. Base excision repair involves flipping the mutated base out of the DNA helix and repairing the base alone. There are two main enzymes used, DNA glycosylases and AP endonucleases. The DNA glycosylase is used to break the beta-N glycosidic bond to create an AP site. AP endonuclease recognizes this site and nicks the damaged DNA on the 5 side (upstream) of the AP site creating a free 3-OH. DNA polymerase, Pol I (human pol beta), extends the DNA from the free 3-OH using its exonuclease activity to replace the nucleotide of the damaged base, as well as a few downstream, followed by sealing of the new DNA strand by DNA ligase. In mammalian cells, this is done by LigIII in complex with the scaffold protein XRCC1. Usually, BER is divided into short-patch repair (where a single nucleotide is replaced) or long-patch repair (where 2-10 nucleotides are replaced). Mammalian long-patch repair includes PCNA and pol delta/epsilon for nucleotide resynthesis, FEN1 to cut of the flap including the damaged base, and LigI. 7-Methyladenine is part of the base excision repair pathway. In this pathway, alkylated DNA is hydrolysed via the enzyme DNA-3-methyladenine glycosylase II (EC 3.2.2.21), releasing 3-methyladenine, 3-methylguanine, 7-methylguanine and 7-methyladenine. This enzyme is responsible for the hydrolysis of the deoxyribose N-glycosidic bond to excise 3-methyladenine, and 7-methylguanine from the damaged DNA polymer formed by alkylation lesions.

Tyramine

C8H11NO (137.0840596)

Tyramine is a monoamine compound derived from the amino acid tyrosine. Tyramine is metabolized by the enzyme monoamine oxidase. In foods, it is often produced by the decarboxylation of tyrosine during fermentation or decay. Foods containing considerable amounts of tyramine include fish, chocolate, alcoholic beverages, cheese, soy sauce, sauerkraut, and processed meat. A large dietary intake of tyramine can cause an increase in systolic blood pressure of 30 mmHg or more. Tyramine acts as a neurotransmitter via a G protein-coupled receptor with high affinity for tyramine called TA1. The TA1 receptor is found in the brain as well as peripheral tissues including the kidney. An indirect sympathomimetic, Tyramine can also serve as a substrate for adrenergic uptake systems and monoamine oxidase so it prolongs the actions of adrenergic transmitters. It also provokes transmitter release from adrenergic terminals. Tyramine is a biomarker for the consumption of cheese [Spectral] Tyramine (exact mass = 137.08406) and L-Methionine (exact mass = 149.05105) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX.

Glucosamine

C6H13NO5 (179.0793688)

Glucosamine (C6H13NO5) is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Glucosamine is part of the structure of two polysaccharides, chitosan and chitin. Glucosamine is one of the most abundant monosaccharides. Produced commercially by the hydrolysis of shellfish exoskeletons or, less commonly, by fermentation of a grain such as corn or wheat, glucosamine has many names depending on country. Although a common dietary supplement, there is little evidence that it is effective for relief of arthritis or pain, and is not an approved prescription drug. In the United States, glucosamine is not approved by the Food and Drug Administration for medical use in humans. Since glucosamine is classified as a dietary supplement, evidence of safety and efficacy is not required as long as it is not advertised as a treatment for a medical condition. Nevertheless, glucosamine is a popular alternative medicine used by consumers for the treatment of osteoarthritis. Glucosamine is also extensively used in veterinary medicine as an unregulated but widely accepted supplement. Treatment with oral glucosamine is commonly used for the treatment of osteoarthritis. Since glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, supplemental glucosamine may help to rebuild cartilage and treat arthritis. However, there is little evidence that any clinical effect of glucosamine works this way. Its use as a therapy for osteoarthritis appears safe but there is conflicting evidence as to its effectiveness. Glucosamine is naturally present in the shells of shellfish, animal bones, bone marrow, and fungi. D-Glucosamine is made naturally in the form of glucosamine-6-phosphate, and is the biochemical precursor of all nitrogen-containing sugars. Specifically in humans, glucosamine-6-phosphate is synthesized from fructose 6-phosphate and glutamine by glutamine—fructose-6-phosphate transaminase as the first step of the hexosamine biosynthesis pathway. The end-product of this pathway is uridine diphosphate N-acetylglucosamine (UDP-GlcNAc), which is then used for making glycosaminoglycans, proteoglycans, and glycolipids. As the formation of glucosamine-6-phosphate is the first step for the synthesis of these products, glucosamine may be important in regulating their production; however, the way that the hexosamine biosynthesis pathway is actually regulated, and whether this could be involved in contributing to human disease remains unclear. Present in mucopolysaccharides and in polysaccharides found in bacteria, fungi, higher plants, invertebrates, vertebrates, antibiotics and UDP complexes.

L-Norleucine

C6H13NO2 (131.0946238)

L-Norleucine, also known as L-aminohexanoate or caprine, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Thus, L-norleucine is considered to be a fatty acid lipid molecule. An unnatural amino acid that is used experimentally to study protein structure and function. L-Norleucine is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. L-Norleucine exists in all eukaryotes, ranging from yeast to humans. Outside of the human body, L-Norleucine has been detected, but not quantified in cow milk. This could make L-norleucine a potential biomarker for the consumption of these foods. It binds reversibly to the kringle domain of plasminogen and blocks the binding of plasminogen to fibrin and its activation to plasmin.

Pyroglutamic acid

C5H7NO3 (129.0425912)

Pyroglutamic acid (5-oxoproline) is a cyclized derivative of L-glutamic acid. It is an uncommon amino acid derivative in which the free amino group of glutamic acid cyclizes to form a lactam. It is formed nonenzymatically from glutamate, glutamine, and gamma-glutamylated peptides, but it can also be produced by the action of gamma-glutamylcyclotransferase on an L-amino acid. Elevated blood levels may be associated with problems of glutamine or glutathione metabolism. This compound is found in substantial amounts in brain tissue and other tissues in bound form, especially skin. It is also present in plant tissues. It is sold, over the counter, as a "smart drug" for improving blood circulation in the brain. Pyroglutamate in the urine is a biomarker for the consumption of cheese. When present in sufficiently high levels, pyroglutamic acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of pyroglutamic acid are associated with at least five inborn errors of metabolism including 5-oxoprolinuria, 5-oxoprolinase deficiency, glutathione synthetase deficiency, hawkinsinuria, and propionic acidemia. Pyroglutamic acid is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. It has been shown that pyroglutamic acid releases GABA from the cerebral cortex and displays anti-anxiety effects in a simple approach-avoidance conflict situation in the rat. In clinical pharmacology experiments, pyroglutamic acid significantly shortens the plasma half-life of ethanol during acute intoxication. Found in vegetables, fruits and molasses. A cyclized derivative of L-glutamic acid. It is an uncommon amino acid derivative in which the free amino group of glutamic acid cyclizes to form a lactam.

Uracil

C4H4N2O2 (112.0272764)

Uracil, also known as U, belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Uracil is a common naturally occurring pyrimidine found in RNA. It base pairs with adenine and is replaced by thymine in DNA. Uracil is one of the four nucleobases in RNA that are represented by the letters A, G, C and U. Methylation of uracil produces thymine. The name "uracil" was coined in 1885 by the German chemist Robert Behrend, who was attempting to synthesize derivatives of uric acid. Originally discovered in 1900, uracil was isolated by hydrolysis of yeast nuclein that was found in bovine thymus and spleen, herring sperm, and wheat germ. Uracil exists in all living species, ranging from bacteria to plants to humans. Uracils use in the body is to help carry out the synthesis of many enzymes necessary for cell function through bonding with riboses and phosphates. Uracil serves as an allosteric regulator and a coenzyme for many important biochemical reactions. Uracil (via the nucleoside uridine) can be phosphorylated by various kinases to produce UMP, UDP and UTP. UDP and UTP regulate carbamoyl phosphate synthetase II (CPSase II) activity in animals. Uracil is also involved in the biosynthesis of polysaccharides and in the transport of sugars containing aldehydes. Within humans, uracil participates in a number of enzymatic reactions. In particular, uracil and ribose 1-phosphate can be biosynthesized from uridine; which is mediated by the enzyme uridine phosphorylase 2. In addition, uracil can be converted into dihydrouracil through the action of the enzyme dihydropyrimidine dehydrogenase [NADP(+)]. Uracil is rarely found in DNA, and this may have been an evolutionary change to increase genetic stability. This is because cytosine can deaminate spontaneously to produce uracil through hydrolytic deamination. Therefore, if there were an organism that used uracil in its DNA, the deamination of cytosine (which undergoes base pairing with guanine) would lead to formation of uracil (which would base pair with adenine) during DNA synthesis. Uracil can be used for drug delivery and as a pharmaceutical. When elemental fluorine reacts with uracil, it produces 5-fluorouracil. 5-Fluorouracil is an anticancer drug (antimetabolite) that mimics uracil during the nucleic acid (i.e. RNA) synthesis and transcription process. Because 5-fluorouracil is similar in shape to, but does not undergo the same chemistry as, uracil, the drug inhibits RNA replication enzymes, thereby blocking RNA synthesis and stopping the growth of cancerous cells. Uracil is a common and naturally occurring pyrimidine derivative. Originally discovered in 1900, it was isolated by hydrolysis of yeast nuclein that was found in bovine thymus and spleen, herring sperm, and wheat germ. It is a planar, unsaturated compound that has the ability to absorb light. Uracil. CAS Common Chemistry.

N-Acetyl-D-glucosamine

C8H15NO6 (221.089933)

N-Acetyl-D-Glucosamine (N-acetlyglucosamine) is a monosaccharide derivative of glucose. Chemically it is an amide between glucosamine and acetic acid. A single N-acetlyglucosamine moiety linked to serine or threonine residues on nuclear and cytoplasmic proteins -O-GlcNAc, is an ubiquitous post-translational protein modification. O-GlcNAc modified proteins are involved in sensing the nutrient status of the surrounding cellular environment and adjusting the activity of cellular proteins accordingly. O-GlcNAc regulates cellular responses to hormones such as insulin, initiates a protective response to stress, modulates a cells capacity to grow and divide, and regulates gene transcription. In humans, it exists in skin, cartilage and blood vessel as a component of hyaluronic acid, and bone tissue, cornea and aorta as a component of keratan sulfate. (PMID 16237703).

Glucose

C6H12O6 (180.0633852)

Glucose, also known as D-glucose or dextrose, is a member of the class of compounds known as hexoses. Hexoses are monosaccharides in which the sugar unit is a is a six-carbon containing moiety. Glucose contains an aldehyde group and is therefore referred to as an aldohexose. The glucose molecule can exist in an open-chain (acyclic) and ring (cyclic) form, the latter being the result of an intramolecular reaction between the aldehyde C atom and the C-5 hydroxyl group to form an intramolecular hemiacetal. In aqueous solution, both forms are in equilibrium and at pH 7 the cyclic one is predominant. Glucose is a neutral, hydrophilic molecule that readily dissolves in water. It exists as a white crystalline powder. Glucose is the primary source of energy for almost all living organisms. As such, it is the most abundant monosaccharide and the most widely used aldohexose in living organisms. When not circulating freely in blood (in animals) or resin (in plants), glucose is stored as a polymer. In plants it is mainly stored as starch and amylopectin and in animals as glycogen. Glucose is produced by plants through the photosynthesis using sunlight, water and carbon dioxide where it is used as an energy and a carbon source Glucose is particularly abundant in fruits and other parts of plants in its free state. Foods that are particularly rich in glucose are honey, agave, molasses, apples (2g/100g), grapes (8g/100g), oranges (8.5g/100g), jackfruit, dried apricots, dates (32 g/100g), bananas (5.8 g/100g), grape juice, sweet corn, Glucose is about 75\\\\% as sweet as sucrose and about 50\\\\% as sweet as fructose. Sweetness is detected through the binding of sugars to the T1R3 and T1R2 proteins, to form a G-protein coupled receptor that is the sweetness receptor in mammals. Glucose was first isolated from raisins in 1747 by the German chemist Andreas Marggraf. It was discovered in grapes by Johann Tobias Lowitz in 1792 and recognized as different from cane sugar (sucrose). Industrially, glucose is mainly used for the production of fructose and in the production of glucose-containing foods. In foods, it is used as a sweetener, humectant, to increase the volume and to create a softer mouthfeel. Various sources of glucose, such as grape juice (for wine) or malt (for beer), are used for fermentation to ethanol during the production of alcoholic beverages. Glucose is found in many plants as glucosides. A glucoside is a glycoside that is derived from glucose. Glucosides are common in plants, but rare in animals. Glucose is produced when a glucoside is hydrolyzed by purely chemical means or decomposed by fermentation or enzymes. Glucose can be obtained by the hydrolysis of carbohydrates such as milk sugar (lactose), cane sugar (sucrose), maltose, cellulose, and glycogen. Glucose is a building block of the disaccharides lactose and sucrose (cane or beet sugar), of oligosaccharides such as raffinose and of polysaccharides such as starch and amylopectin, glycogen or cellulose. For most animals, while glucose is normally obtained from the diet, it can also be generated via gluconeogenesis. Gluconeogenesis is a metabolic pathway that results in the generation of glucose from certain non-carbohydrate carbon substrates. Gluconeogenesis is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms.

Chlorpyrifos

C9H11Cl3NO3PS (348.9262836000001)

A study of the effects of chlorpyrifos on humans exposed over time showed that people exposed to high levels have autoimmune antibodies that are common in people with autoimmune disorders. There is a strong correlation to chronic illness associated with autoimmune disorders after exposure to chlorpyrifos. Among 50 farm pesticides studied, chlorpyrifos was one of two found to be associated with higher risks of lung cancer among frequent pesticide applicators than among infrequent or non-users. Pesticide applicators as a whole were found to have a 50\\% lower cancer risk than the general public, which is attributable to the nearly 50\\% lower smoking rate found among farm workers. However, applicators of chlorpyrifos had a 15\\% lower cancer risk than the general public, which the study suggests indicates a likely link between chlorpyrifos application and lung cancer. Chlorpyrifos (IUPAC name: O,O-diethyl O-3,5,6-trichloropyridin-2-yl phosphorothioate) is a crystalline organophosphate insecticide. It was introduced in 1965 by Dow Chemical Company and is known by many trade names (see table), including Dursban and Lorsban. It acts on the nervous system of insects by inhibiting acetylcholinesterase. Chlorpyrifos is an organophosphate, with potential for both acute toxicity at larger amounts and neurological effects in fetuses and children even at very small amounts. For acute effects, the EPA classifies chlorpyrifos as Class II: moderately toxic. The oral LD50 for chlorpyrifos in experimental animals is 32 to 1000 mg/kg. The dermal LD50 in rats is greater than 2000 mg/kg and 1000 to 2000 mg/kg in rabbits. The 4-hour inhalation LC50 for chlorpyrifos in rats is greater than 200 mg/m3. First registered in 1965 and marketed by Dow Chemical under the tradenames Dursban, Lorsban and Renoban, chlorpyrifos was a well known home and garden insecticide, and at one time it was one of the most widely used household pesticides in the US.

1-Methyladenosine

C11H15N5O4 (281.11239900000004)

1-Methyladenosine, also known as M1A, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Precise m6A mapping by m6A-CLIP/IP (briefly m6A-CLIP) revealed that a majority of m6A locates in the last exon of mRNAs in multiple tissues/cultured cells of mouse and human, and the m6A enrichment around stop codons is a coincidence that many stop codons locate round the start of last exons where m6A is truly enriched. The methylation of adenosine is directed by a large m6A methyltransferase complex containing METTL3 as the SAM-binding sub-unit. Insulin-like growth factor-2 mRNA-binding proteins 1, 2, and 3 (IGF2BP1-3) are reported as a novel class of m6A readers. 1-Methyladenosine is an RNA modification originating essentially from two different reaction types, one catalyzed by enzymes and the other the result of the reaction of RNA with certain alkylating agents. 1-Methyladenosine is an RNA modification originating essentially from two different reaction types, one catalyzed by enzymes and the other the result of the reaction of RNA with certain alkylating agents.

Phthalic acid

C8H6O4 (166.0266076)

Phthalic acid is an aromatic dicarboxylic acid, with formula C6H4(COOH)2. Phthalic acid is used mainly in the form of the anhydride to produce other chemicals such as dyes, perfumes, saccharin, phthalates and many other useful products. Phthalic acid, when found in tissues or biofluids arises from exposure to these phthalate products. Phthalate is an environmental chemical of heightened public concern because reports of its potential risk to male reproductive health (PMID 16804814), being significantly associated with reduced sperm concentration to pesticide concentration in mens urine (PMID 16804812). Within the reproductive tract, the male is exquisitely vulnerable to the effects of anti-androgens during development due the reliance on the synthesis and action of androgens for the masculinization of the male reproductive tract. The ability of phthalates to suppress androgen synthesis during development and to induce testicular dysgenesis together with cryptorchidism and hypospadias has raised considerable concern.

Taurocholate

C26H45NO7S (515.291658)

Taurocholic acid is a bile acid and is the product of the conjugation of cholic acid with taurine. Its sodium salt is the chief ingredient of the bile of carnivorous animals. Bile acids are steroid acids found predominantly in the bile of mammals. The distinction between different bile acids is minute, depending only on the presence or absence of hydroxyl groups on positions 3, 7, and 12. Bile acids are physiological detergents that facilitate excretion, absorption, and transport of fats and sterols in the intestine and liver. Bile acids are also steroidal amphipathic molecules derived from the catabolism of cholesterol. They modulate bile flow and lipid secretion, are essential for the absorption of dietary fats and vitamins, and have been implicated in the regulation of all the key enzymes involved in cholesterol homeostasis. Bile acids recirculate through the liver, bile ducts, small intestine, and portal vein to form an enterohepatic circuit. They exist as anions at physiological pH, and consequently require a carrier for transport across the membranes of the enterohepatic tissues. The unique detergent properties of bile acids are essential for the digestion and intestinal absorption of hydrophobic nutrients. Bile acids have potent toxic properties (e.g. membrane disruption) and there are a plethora of mechanisms to limit their accumulation in blood and tissues (PMID: 11316487, 16037564, 12576301, 11907135). Taurocholic acid, as with all bile acids, acts as a detergent to solubilize fats for absorption and is itself absorbed. It is used as a cholagogue and choleretic (a bile purging agent). Hydrolysis of taurocholic acid yields taurine, a nonessential amino acid. Taurocholic acid is one of the main components of urinary nonsulfated bile acids in biliary atresia. Raised levels of taurocholate in fetal serum in obstetric cholestasis may result in the development of a fetal dysrhythmia and sudden intra-uterine death (PMID: 3944741, 11256973). Taurocholic acid.

C24H48O2 (368.3654108)

Lignoceric acid, also known as N-tetracosanoic acid or tetraeicosanoate, is a member of the class of compounds known as very long-chain fatty acids. Very long-chain fatty acids are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. Thus, lignoceric acid is considered to be a fatty acid lipid molecule. Lignoceric acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Lignoceric acid can be found in a number of food items such as hazelnut, cheese, rye bread, and cetacea (dolphin, porpoise, whale), which makes lignoceric acid a potential biomarker for the consumption of these food products. Lignoceric acid can be found primarily in blood and feces, as well as in human fibroblasts tissue. Lignoceric acid exists in all eukaryotes, ranging from yeast to humans. In humans, lignoceric acid is involved in a couple of metabolic pathways, which include adrenoleukodystrophy, x-linked and beta oxidation of very long chain fatty acids.

Phenylacetylglycine

C10H11NO3 (193.0738896)

Phenylacetylglycine is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction:. acyl-CoA + glycine < -- > CoA + N-acylglycine. Phenylacetylglycine or PAG is a glycine conjugate of phenylacetic acid. Phenylacetic acid may arise from exposure to styrene (plastic) or through the consumption of fruits and vegetables. Phenylacetic acid is used in some perfumes, possessing a honey-like odour in low concentrations, and is also used in penicillin G production. PAG is a putative biomarker of phospholipidosis. Urinary PAG is elevated in animals exhibiting abnormal phospholipid accumulation in many tissues and may thus be useful as a surrogate biomarker for phospholipidosis. (PMID: 15764292) The presence of phenylacetylglycine in urine has been confirmed for dogs, rats and mice. However, the presence of this compound in human urine is controversial. GC-MS studies have not found this compound (PMID: 7492634) while NMR studies claimed to have identified it (PMID: 21167146).

Phenylethylamine

C8H11N (121.0891446)

Phenylethylamine (PEA) is an aromatic amine, which is a colorless liquid at room temperature. It is soluble in water, ethanol, and ether. Similar to other low-molecular-weight amines, it has a fishy odor. Upon exposure to air, it forms a solid carbonate salt with carbon dioxide. Phenethylamine is strongly basic and forms a stable crystalline hydrochloride salt with a melting point of 217 °C. Phenethylamine is also a skin irritant and possible sensitizer. Phenethylamine also has a constitutional isomer (+)-phenylethylamine (1-phenylethylamine), which has two stereoisomers: (R)-(+)-1-phenylethylamine and (S)-(-)-1-phenylethylamine. In the human brain, 2-phenethylamine is believed to function as a neuromodulator or neurotransmitter (a trace amine). Phenethylamine can be biosynthesized from the amino acid phenylalanine by enzymatic decarboxylation. It is also found in many foods such as chocolate, especially after microbial fermentation. However trace amounts from food are quickly metabolized by the enzyme MAO-B (into phenylacetic acid), preventing significant concentrations from reaching the brain. Phenylethylamine is a precursor to the neurotransmitter phenylethanolamine. High levels of PEA have been found in the urine of schizophrenics but it is not significantly elevated in the serum or CSF of schizophrenics (PMID:7906896, PMID:7360842).¬† Urinary levels of PEA are significantly lower in children with attention deficit hyperactivity disorder (ADHD) (PMID:12205654).¬† It has been found that PEA is the primary compound found in carnivore (especially cat) urine that leads to rodent (mouse and rat) avoidance. In other words, phenylethylamine is useful for scaring off rodent pests.¬† Quantitative HPLC analysis across 38 mammalian species has shown that PEA production in urine is especially enhanced in carnivores, with some producing >3,000-fold more than herbivores (PMID:21690383). Phenethylamine has been found to be a metabolite of Bacillus, Enterococcus and Lactobacillus (PMID:22953951; PMID:17307265; PMID:16630269).

L-Alanine

C3H7NO2 (89.0476762)

Alanine (Ala), also known as L-alanine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-alanine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Alanine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, non-polar amino acid. In humans, alanine is a non-essential amino acid that can be easily made in the body from either the conversion of pyruvate or the breakdown of the dipeptides carnosine and anserine. Alanine can be also synthesized from branched chain amino acids such as valine, leucine, and isoleucine. Alanine is produced by reductive amination of pyruvate through a two-step process. In the first step, alpha-ketoglutarate, ammonia and NADH are converted by the enzyme known glutamate dehydrogenase to glutamate, NAD+ and water. In the second step, the amino group of the newly-formed glutamate is transferred to pyruvate by an aminotransferase enzyme, regenerating the alpha-ketoglutarate, and converting the pyruvate to alanine. The net result is that pyruvate and ammonia are converted to alanine. In mammals, alanine plays a key role in glucose–alanine cycle between tissues and liver. In muscle and other tissues that degrade amino acids for fuel, amino groups are collected in the form of glutamate by transamination. Glutamate can then transfer its amino group to pyruvate, a product of muscle glycolysis, through the action of alanine aminotransferase, forming alanine and alpha-ketoglutarate. The alanine enters the bloodstream and is transported to the liver. The alanine aminotransferase reaction takes place in reverse in the liver, where the regenerated pyruvate is used in gluconeogenesis, forming glucose which returns to the muscles through the circulation system. Alanine is highly concentrated in muscle and is one of the most important amino acids released by muscle, functioning as a major energy source. Plasma alanine is often decreased when the BCAA (branched-chain amino acids) are deficient. This finding may relate to muscle metabolism. Alanine is highly concentrated in meat products and other high-protein foods like wheat germ and cottage cheese. Alanine is an important participant as well as a regulator of glucose metabolism. Alanine levels parallel blood sugar levels in both diabetes and hypoglycemia, and alanine is reduced in both severe hypoglycemia and the ketosis of diabetes. Alanine is an important amino acid for lymphocyte reproduction and immunity. Alanine therapy has helped dissolve kidney stones in experimental animals. Normal alanine metabolism, like that of other amino acids, is highly dependent upon enzymes that contain vitamin B6. Alanine, like GABA, taurine, and glycine, is an inhibitory neurotransmitter in the brain (http://www.dcnutrition.com/AminoAcids/). L-Alanine. CAS Common Chemistry.

Indole

C8H7N (117.0578462)

Indole is an aromatic heterocyclic organic compound. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. The participation of the nitrogen lone electron pair in the aromatic ring means that indole is not a base, and it does not behave like a simple amine. Indole is a microbial metabolite and it can be produced by bacteria as a degradation product of the amino acid tryptophan. It occurs naturally in human feces and has an intense fecal smell. At very low concentrations, however, indole has a flowery smell and is a constituent of many flower scents (such as orange blossoms) and perfumes. As a volatile organic compound, indole has been identified as a fecal biomarker of Clostridium difficile infection (PMID: 30986230). Natural jasmine oil, used in the perfume industry, contains around 2.5\\\\\% of indole. Indole also occurs in coal tar. Indole has been found to be produced in a number of bacterial genera including Alcaligenes, Aspergillus, Escherichia, and Pseudomonas (PMID: 23194589, 2310183, 9680309). Indole plays a role in bacterial biofilm formation, bacterial motility, bacterial virulence, plasmid stability, and antibiotic resistance. It also functions as an intercellular signalling molecule (PMID: 26115989). Recently, it was determined that the bacterial membrane-bound histidine sensor kinase (HK) known as CpxA acts as a bacterial indole sensor to facilitate signalling (PMID: 31164470). It has been found that decreased indole concentrations in the gut promote bacterial pathogenesis, while increased levels of indole in the gut decrease bacterial virulence gene expression (PMID: 31164470). As a result, enteric pathogens sense a gradient of indole concentrations in the gut to migrate to different niches and successfully establish an infection.

Cyclic AMP

C10H12N5O6P (329.0525182)

Cyclic amp, also known as camp or adenosine 3,5-cyclic monophosphate, is a member of the class of compounds known as 3,5-cyclic purine nucleotides. 3,5-cyclic purine nucleotides are purine nucleotides in which the oxygen atoms linked to the C3 and C5 carbon atoms of the ribose moiety are both bonded the same phosphorus atom of the phosphate group. Cyclic amp is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Cyclic amp can be found in a number of food items such as green vegetables, java plum, borage, and wakame, which makes cyclic amp a potential biomarker for the consumption of these food products. Cyclic amp can be found primarily in blood, cerebrospinal fluid (CSF), feces, and urine, as well as throughout all human tissues. Cyclic amp exists in all living species, ranging from bacteria to humans. In humans, cyclic amp is involved in several metabolic pathways, some of which include dopamine activation of neurological reward system, excitatory neural signalling through 5-HTR 4 and serotonin, intracellular signalling through PGD2 receptor and prostaglandin D2, and thioguanine action pathway. Cyclic amp is also involved in several metabolic disorders, some of which include adenosine deaminase deficiency, gout or kelley-seegmiller syndrome, purine nucleoside phosphorylase deficiency, and adenine phosphoribosyltransferase deficiency (APRT). Moreover, cyclic amp is found to be associated with chronic renal failure, headache, meningitis, and hypoxic-ischemic encephalopathy. Cyclic adenosine monophosphate (cAMP, cyclic AMP, or 3,5-cyclic adenosine monophosphate) is a second messenger important in many biological processes. cAMP is a derivative of adenosine triphosphate (ATP) and used for intracellular signal transduction in many different organisms, conveying the cAMP-dependent pathway. It should not be confused with 5-AMP-activated protein kinase (AMP-activated protein kinase) . Cyclic AMP (cAMP) or cyclic adenosine monophosphate is an adenine nucleotide containing one phosphate group which is esterified to both the 3- and 5-positions of the sugar moiety. cAMP is found in all organisms ranging from bacteria to plants to animals. In humans and other mammals it is a second messenger and a key intracellular regulator, functioning as a mediator of activity for a number of hormones, including epinephrine, glucagon and ACTH. cAMP is synthesized from ATP by adenylate cyclase. Adenylate cyclase is located at the inner side of cell membranes. Adenylate cyclase is activated by the hormones glucagon and adrenaline and by G protein. Liver adenylate cyclase responds more strongly to glucagon, and muscle adenylate cyclase responds more strongly to adrenaline. cAMP decomposition into AMP is catalyzed by the enzyme phosphodiesterase. cAMP is primarily used for intracellular signal transduction, such as transferring into cells the effects of hormones like glucagon and adrenaline, which cannot pass through the plasma membrane. cAMP is also involved in the activation of protein kinases. In addition, cAMP binds to and regulates the function of ion channels such as the HCN channels. Hyperpolarization-activated cyclic nucleotide–gated (HCN) channels are integral membrane proteins that serve as nonselective voltage-gated cation channels in the plasma membranes of heart and brain cells. HCN channels are sometimes referred to as pacemaker channels because they help to generate rhythmic activity within groups of heart and brain cells.

C18H39NO3 (317.2929784)

Phytosphingosine is a phospholipid. Phospholipids are a class of lipids and a major component of all biological membranes; sphingolipid metabolites, such as sphingosine and ceramide, are highly bioactive compounds and are involved in diverse cell processes, including cell-cell interaction, cell proliferation, differentiation, and apoptosis. Phytosphingosine is also one of the most widely distributed natural sphingoid bases, which is abundant in fungi and plants, and also found in animals including humans. Phytosphingosine is structurally similar to sphingosine; phytosphingosine possesses a hydroxyl group at C-4 of the sphingoid long-chain base. The physiological roles of phytosphingosine are largely unknown. Phytosphingosine induces apoptosis in human T-cell lymphoma and non-small cell lung cancer cells, and induces caspase-independent cytochrome c release from mitochondria. In the presence of caspase inhibitors, phytosphingosine-induced apoptosis is almost completely suppressed, suggesting that phytosphingosine-induced apoptosis is largely dependent on caspase activities.

Flavin mononucleotide

C17H21N4O9P (456.1046106)

Flavin mononucleotide, also known as riboflavin 5-monophosphate or riboflavine dihydrogen phosphate, is a member of the class of compounds known as flavin nucleotides. Flavin nucleotides are nucleotides containing a flavin moiety. Flavin is a compound that contains the tricyclic isoalloxazine ring system, which bears 2 oxo groups at the 2- and 4-positions. Flavin mononucleotide is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Flavin mononucleotide can be found in a number of food items such as spinach, elliotts blueberry, tea leaf willow, and black mulberry, which makes flavin mononucleotide a potential biomarker for the consumption of these food products. Flavin mononucleotide can be found primarily in blood, as well as throughout most human tissues. Flavin mononucleotide exists in all living species, ranging from bacteria to humans. In humans, flavin mononucleotide is involved in several metabolic pathways, some of which include riboflavin metabolism, pyrimidine metabolism, beta-alanine metabolism, and doxorubicin metabolism pathway. Flavin mononucleotide is also involved in several metabolic disorders, some of which include beta ureidopropionase deficiency, UMP synthase deficiency (orotic aciduria), carnosinuria, carnosinemia, and hypophosphatasia. Moreover, flavin mononucleotide is found to be associated with anorexia nervosa. Flavin mononucleotide (FMN), or riboflavin-5′-phosphate, is a biomolecule produced from riboflavin (vitamin B2) by the enzyme riboflavin kinase and functions as prosthetic group of various oxidoreductases including NADH dehydrogenase as well as cofactor in biological blue-light photo receptors. During the catalytic cycle, a reversible interconversion of the oxidized (FMN), semiquinone (FMNH•) and reduced (FMNH2) forms occurs in the various oxidoreductases. FMN is a stronger oxidizing agent than NAD and is particularly useful because it can take part in both one- and two-electron transfers. In its role as blue-light photo receptor, (oxidized) FMN stands out from the conventional photo receptors as the signaling state and not an E/Z isomerization .

Uridine 5'-diphosphate

C9H14N2O12P2 (404.0021984)

Uridine 5-diphosphate, also known as 5-UDP, UDP or uridine diphosphoric acid, belongs to the class of organic compounds known as pyrimidine ribonucleoside diphosphates. These are pyrimidine ribonucleotides with diphosphate group linked to the ribose moiety. UDP is also classified as a nucleotide diphosphate. It is an ester of pyrophosphoric acid with the nucleoside uridine. UDP consists of a pyrophosphate group, a pentose sugar ribose, and the nucleobase uracil. UDP exists in all living species, ranging from bacteria to plants to humans. In mammals UDP is an important factor in glycogenesis or the formation of glycogen in the liver. Before glucose can be stored as glycogen in the liver and muscles, the enzyme UDP-glucose pyrophosphorylase forms a UDP-glucose unit by combining glucose 1-phosphate with uridine triphosphate, cleaving a pyrophosphate ion in the process. Then, the enzyme glycogen synthase combines UDP-glucose units to form a glycogen chain. UDP is also an important extracellular pyrimidine signaling molecule that mediates diverse biological effects via P1 and P2 purinergic receptors, such as the uptake of thymidine and proliferation of gliomas. UDP plays a key role in the function of Uridine 5-diphospho-glucuronosyltransferases (UDP-glucuronosyltransferases, UGTs) which catalyze the transfer of the glucuronic acid component of UDP-glucuronic acid to a small hydrophobic molecule. UDP-Glucuronosyltransferases are responsible for the process of glucuronidation, a major part of phase II metabolism. The reaction catalyzed by UGT enzymes involves the addition of a glucuronic acid moiety to xenobiotics and is the most important pathway for the human bodys elimination of the most frequently prescribed drugs. It is also the major pathway for foreign chemical (dietary, environmental, pharmaceutical) removal for most drugs, dietary substances, toxins and endogenous substances. UGT is present in humans, other animals, plants, and bacteria. Famously, UGT enzymes are not present in the genus Felis (PMID: 10862526) and this accounts for a number of unusual toxicities in the cat family. Uridine-5-diphosphate, also known as udp or uridine 5-diphosphoric acid, is a member of the class of compounds known as pyrimidine ribonucleoside diphosphates. Pyrimidine ribonucleoside diphosphates are pyrimidine ribonucleotides with diphosphate group linked to the ribose moiety. Uridine-5-diphosphate is slightly soluble (in water) and a moderately acidic compound (based on its pKa).

Uridine-5-diphosphate exists in all living species, ranging from bacteria to humans. In humans, uridine-5-diphosphate is involved in several metabolic pathways, some of which include morphine action pathway, androgen and estrogen metabolism, estrone metabolism, and amino sugar metabolism. Uridine-5-diphosphate is also involved in several metabolic disorders, some of which include 17-beta hydroxysteroid dehydrogenase III deficiency, acute intermittent porphyria, beta ureidopropionase deficiency, and g(m2)-gangliosidosis: variant B, tay-sachs disease.

Citrulline

C6H13N3O3 (175.0956868)

Citrulline, also known as Cit or δ-ureidonorvaline, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Citrulline has the formula H2NC(O)NH(CH2)3CH(NH2)CO2H. Citrulline exists in all living species, ranging from bacteria to humans. Within humans, citrulline participates in a number of enzymatic reactions. In particular, citrulline can be biosynthesized from carbamoyl phosphate and ornithine which is catalyzed by the enzyme ornithine carbamoyltransferase. In addition, citrulline and L-aspartic acid can be converted into argininosuccinic acid through the action of the enzyme argininosuccinate synthase. In humans, citrulline is involved in the metabolic disorder called argininemia. Citrulline has also been found to be associated with several diseases such as ulcerative colitis, rheumatoid arthritis, and citrullinemia type II. Citrulline has also been linked to several inborn metabolic disorders including argininosuccinic aciduria and fumarase deficiency. Outside of the human body, citrulline is found, on average, in the highest concentration in a few different foods such as wheats, oats, and cucumbers and in a lower concentration in swiss chards, yellow wax beans, and potato. Citrulline has also been detected, but not quantified in several different foods, such as epazotes, lotus, common buckwheats, strawberry guava, and italian sweet red peppers. Citrulline is a potentially toxic compound. Proteins that normally contain citrulline residues include myelin basic protein (MBP), filaggrin, and several histone proteins, whereas other proteins, such as fibrin and vimentin are susceptible to citrullination during cell death and tissue inflammation. Citrulline is also produced as a byproduct of the enzymatic production of nitric oxide from the amino acid arginine, catalyzed by nitric oxide synthase. It is also produced from arginine as a byproduct of the reaction catalyzed by NOS family (NOS; EC1.14.13.39).

Cytidine monophosphate

C9H14N3O8P (323.05184940000004)

Cytidine monophosphate, also known as 5-cytidylic acid and abbreviated CMP, is a nucleotide. It is an ester of phosphoric acid with the nucleoside cytidine. CMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase cytosine. Cytidine monophosphate (CMP) is derived from cytidine triphosphate (CTP) with subsequent loss of two phosphates. The synthesis of the pyrimidines CTP and UTP occurs in the cytoplasm and starts with the formation of carbamoyl phosphate from glutamine and CO2. Next, aspartate undergoes a condensation reaction with carbamoyl-phosphate to form orotic acid. In a subsequent cyclization reaction, the enzyme Aspartate carbamoyltransferase forms N-carbamoyl-aspartate which is converted into dihydroorotic acid by Dihydroorotase. The latter is converted to orotate by Dihydroorotate oxidase. Orotate is covalently linked with a phosphorylated ribosyl unit with Orotate phosphoribosyltransferase (aka "PRPP transferase") catalyzing reaction, yielding orotidine monophosphate (OMP). Orotidine-5-phosphate is decarboxylated by Orotidine-5-phosphate decarboxylase to form uridine monophosphate (UMP). UMP is phosphorylated by two kinases to uridine triphosphate (UTP) via two sequential reactions with ATP. CTP is subsequently formed by amination of UTP by the catalytic activity of CTP synthetase. Cytosine monophosphate (CMP) and uridine monophosphate (UMP) have been prescribed for the treatment of neuromuscular affections in humans. Patients treated with CMP/UMP recover from altered neurological functions. Additionally, the administration of CMP/UMP appears to favour the entry of glucose in the muscle and CMP/UMP may be important in maintaining the level of hepatic glycogen constant during exercise. [PMID:18663991]. Cytidine monophosphate, also known as cmp or cytidylic acid, is a member of the class of compounds known as pyrimidine ribonucleoside monophosphates. Pyrimidine ribonucleoside monophosphates are pyrimidine ribobucleotides with monophosphate group linked to the ribose moiety. Cytidine monophosphate is soluble (in water) and a moderately acidic compound (based on its pKa).

Thiamine

C12H17N4OS (265.1123012)

Thiamine, also known as aneurin or vitamin B1, belongs to the class of organic compounds known as thiamines. Thiamines are compounds containing a thiamine moiety, which is structurally characterized by a 3-[(4-Amino-2-methyl-pyrimidin-5-yl)methyl]-4-methyl-thiazol-5-yl backbone. Thiamine exists in all living species, ranging from bacteria to plants to humans. Thiamine biosynthesis occurs in bacteria, some protozoans, plants, and fungi. Thiamine is a vitamin and an essential nutrient meaning the body cannot synthesize it, and it must be obtained from the diet. It is soluble in water and insoluble in alcohol. Thiamine decomposes if heated. Thiamine was first discovered in 1897 by Umetaro Suzuki in Japan when researching how rice bran cured patients of Beriberi. Thiamine was the first B vitamin to be isolated in 1926 and was first made in 1936. Thiamine plays a key role in intracellular glucose metabolism and it is thought that thiamine inhibits the effect of glucose and insulin on arterial smooth muscle cell proliferation. Thiamine plays an important role in helping the body convert carbohydrates and fat into energy. It is essential for normal growth and development and helps to maintain proper functioning of the heart and the nervous and digestive systems. Thiamine cannot be stored in the body; however, once absorbed, the vitamin is concentrated in muscle tissue. Thiamine has antioxidant, erythropoietic, cognition-and mood-modulatory, antiatherosclerotic, putative ergogenic, and detoxification activities. Natural derivatives of thiamine, such as thiamine monophosphate (ThMP), thiamine diphosphate (ThDP), also sometimes called thiamine pyrophosphate (TPP), thiamine triphosphate (ThTP), and adenosine thiamine triphosphate (AThTP), act as coenzymes in addition to performing unique biological functions. Thiamine deficiency can lead to beriberi, Wernicke–Korsakoff syndrome, optic neuropathy, Leighs disease, African seasonal ataxia (or Nigerian seasonal ataxia), and central pontine myelinolysis. In Western countries, thiamine deficiency is seen mainly in chronic alcoholism. Thiamine supplements or thiamine therapy can be used for the treatment of a number of disorders including thiamine and niacin deficiency states, Korsakovs alcoholic psychosis, Wernicke-Korsakov syndrome, delirium, and peripheral neuritis. In humans, thiamine is involved in the metabolic disorder called 2-methyl-3-hydroxybutyryl-CoA dehydrogenase deficiency. Outside of the human body, Thiamine is found in high quantities in whole grains, legumes, pork, fruits, and yeast and fish. Grain processing removes much of the thiamine content in grains, so in many countries cereals and flours are enriched with thiamine. Thiamine is an essential vitamin. It is found in many foods, some of which are atlantic croaker, wonton wrapper, cereals and cereal products, and turmeric.

Choline

[C5H14NO]+ (104.10753340000001)

Choline is a basic constituent of lecithin that is found in many plants and animal organs. It is important as a precursor of acetylcholine, as a methyl donor in various metabolic processes, and in lipid metabolism. Choline is now considered to be an essential vitamin. While humans can synthesize small amounts (by converting phosphatidylethanolamine to phosphatidylcholine), it must be consumed in the diet to maintain health. Required levels are between 425 mg/day (female) and 550 mg/day (male). Milk, eggs, liver, and peanuts are especially rich in choline. Most choline is found in phospholipids, namely phosphatidylcholine or lecithin. Choline can be oxidized to form betaine, which is a methyl source for many reactions (i.e. conversion of homocysteine into methionine). Lack of sufficient amounts of choline in the diet can lead to a fatty liver condition and general liver damage. This arises from the lack of VLDL, which is necessary to transport fats away from the liver. Choline deficiency also leads to elevated serum levels of alanine amino transferase and is associated with increased incidence of liver cancer. Nutritional supplement. Occurs free and combined in many animal and vegetable foods with highest concentrations found in egg yolk, meat, fish, milk, cereaks and legumes Choline. CAS Common Chemistry.

Acetylcholine

[C7H16NO2]+ (146.1180976)

Acetylcholine (ACh) is a neurotransmitter. Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. Its physiological and pharmacological effects, metabolism, release, and receptors have been well documented in several species. ACh has been considered an important excitatory neurotransmitter in the carotid body (CB). Various nicotinic and muscarinic ACh receptors are present in both afferent nerve endings and glomus cells. Therefore, ACh can depolarize or hyperpolarize the cell membrane depending on the available receptor type in the vicinity. Binding of ACh to its receptor can create a wide variety of cellular responses including opening cation channels (nicotinic ACh receptor activation), releasing Ca2+ from intracellular storage sites (via muscarinic ACh receptors), and modulating activities of K+ and Ca2+ channels. Interactions between ACh and other neurotransmitters (dopamine, adenosine, nitric oxide) have been known, and they may induce complicated responses. Cholinergic biology in the CB differs among species and even within the same species due to different genetic composition. Development and environment influence cholinergic biology. Pharmacological data clearly indicate that both muscarinic and nicotinic acetylcholine receptors have a role in the encoding of new memories. Localized lesions and antagonist infusions demonstrate the anatomical locus of these cholinergic effects, and computational modeling links the function of cholinergic modulation to specific cellular effects within these regions. Acetylcholine has been shown to increase the strength of afferent input relative to feedback, to contribute to theta rhythm oscillations, activate intrinsic mechanisms for persistent spiking, and increase the modification of synapses. These effects might enhance different types of encoding in different cortical structures. In particular, the effects in entorhinal and perirhinal cortex and hippocampus might be important for encoding new episodic memories. The role of ACh in attention has been repeatedly demonstrated in several tasks. Acetylcholine is linked to response accuracy in voluntary and reflexive attention and also to response speed in reflexive attention. It is well known that those with Attention-deficit/hyperactivity disorders tend to be inaccurate and slow to respond. (PMID:17284361, 17011181, 15556286). Acetylcholine has been found to be a microbial product, urinary acetylcholine is produced by Lactobacillus (PMID:24621061).

1-Methylnicotinamide

[C7H9N2O]+ (137.0714844)

γ-Aminobutyric acid

C4H9NO2 (103.0633254)

gamma-Aminobutyric acid (GABA) is an inhibitory neurotransmitter found in the nervous systems of widely divergent species, including humans. It is the chief inhibitory neurotransmitter in the vertebrate central nervous system. In vertebrates, GABA acts at inhibitory synapses in the brain. It acts by binding to specific transmembrane receptors in the plasma membrane of both pre- and postsynaptic neurons. This binding causes the opening of ion channels to allow either the flow of negatively-charged chloride ions into the cell or positively-charged potassium ions out of the cell. This will typically result in a negative change in the transmembrane potential, usually causing hyperpolarization. Three general classes of GABA receptor are known (PMID: 10561820). These include GABA-A and GABA-C ionotropic receptors, which are ion channels themselves, and GABA-B metabotropic receptors, which are G protein-coupled receptors that open ion channels via intermediaries known as G proteins (PMID: 10561820). Activation of the GABA-B receptor by GABA causes neuronal membrane hyperpolarization and a resultant inhibition of neurotransmitter release. In addition to binding sites for GABA, the GABA-A receptor has binding sites for benzodiazepines, barbiturates, and neurosteroids. GABA-A receptors are coupled to chloride ion channels. Therefore, activation of the GABA-A receptor induces increased inward chloride ion flux, resulting in membrane hyperpolarization and neuronal inhibition (PMID: 10561820). After release into the synapse, free GABA that does not bind to either the GABA-A or GABA-B receptor complexes can be taken up by neurons and glial cells. Four different GABA membrane transporter proteins (GAT-1, GAT-2, GAT-3, and BGT-1), which differ in their distribution in the CNS, are believed to mediate the uptake of synaptic GABA into neurons and glial cells. The GABA-A receptor subtype regulates neuronal excitability and rapid changes in fear arousal, such as anxiety, panic, and the acute stress response (PMID: 10561820). Drugs that stimulate GABA-A receptors, such as the benzodiazepines and barbiturates, have anxiolytic and anti-seizure effects via GABA-A-mediated reduction of neuronal excitability, which effectively raises the seizure threshold. GABA-A antagonists produce convulsions in animals and there is decreased GABA-A receptor binding in a positron emission tomography (PET) study of patients with panic disorder. Neurons that produce GABA as their output are called GABAergic neurons and have chiefly inhibitory action at receptors in the vertebrate. Medium spiny neurons (MSNs) are a typical example of inhibitory CNS GABAergic cells. GABA has been shown to have excitatory roles in the vertebrate, most notably in the developing cortex. Organisms synthesize GABA from glutamate using the enzyme L-glutamic acid decarboxylase and pyridoxal phosphate as a cofactor (PMID: 12467378). It is worth noting that this involves converting the principal excitatory neurotransmitter (glutamate) into the principal inhibitory one (GABA). Drugs that act as agonists of GABA receptors (known as GABA analogs or GABAergic drugs), or increase the available amount of GABA typically have relaxing, anti-anxiety, and anti-convulsive effects. GABA is found to be deficient in cerebrospinal fluid and the brain in many studies of experimental and human epilepsy. Benzodiazepines (such as Valium) are useful in status epilepticus because they act on GABA receptors. GABA increases in the brain after administration of many seizure medications. Hence, GABA is clearly an antiepileptic nutrient. Inhibitors of GAM metabolism can also produce convulsions. Spasticity and involuntary movement syndromes, such as Parkinsons, Friedreichs ataxia, tardive dyskinesia, and Huntingtons chorea, are all marked by low GABA when amino acid levels are studied. Trials of 2 to 3 g of GABA given orally have been effective in various epilepsy and spasticity syndromes. Agents that elevate GABA are als... Gamma-aminobutyric acid, also known as gaba or 4-aminobutanoic acid, belongs to gamma amino acids and derivatives class of compounds. Those are amino acids having a (-NH2) group attached to the gamma carbon atom. Thus, gamma-aminobutyric acid is considered to be a fatty acid lipid molecule.

Disodium guanylate is often found in instant noodles, potato chips and snacks, savoury rice, tinned vegetables, cured meats, and packet soup. As it is a fairly expensive additive, it is usually not used independently of glutamic acid or monosodium glutamate (MSG), which also contribute umami. If inosinate and guanylate salts are present in a list of ingredients but MSG does not appear to be, the glutamic acid is likely provided as part of another ingredient, such as a processed soy protein complex (hydrolyzed soy protein), autolyzed yeast, or soy sauce. 5'-Guanylic acid (5'-GMP) is involved in several metabolic disorders, including the AICA-ribosiduria pathway, adenosine deaminase deficiency, adenine phosphoribosyltransferase deficiency (aprt), and the 2-hydroxyglutric aciduria pathway. 5'-Guanylic acid (5'-GMP) is involved in several metabolic disorders, including the AICA-ribosiduria pathway, adenosine deaminase deficiency, adenine phosphoribosyltransferase deficiency (aprt), and the 2-hydroxyglutric aciduria pathway.

Pyrrole

C4H5N (67.042197)

Pyrrole is found in corn. Pyrrole is a flavouring ingredient Pyrrole has very low basicity compared to conventional amines and some other aromatic compounds like pyridine. This decreased basicity is attributed to the delocalization of the lone pair of electrons of the nitrogen atom in the aromatic ring. Pyrrole is a very weak base with a pKaH of about 4. Protonation results in loss of aromaticity, and is, therefore, unfavorable. Pyrrole is a heterocyclic aromatic organic compound, a five-membered ring with the formula C4H4NH. Substituted derivatives are also called pyrroles. For example, C4H4NCH3 is N-methylpyrrole. Porphobilinogen is a trisubstituted pyrrole, which is the biosynthetic precursor to many natural products. The starting materials in the Piloty-Robinson pyrrole synthesis are 2 equivalents of an aldehyde and hydrazine. The product is a pyrrole with specific substituents in the 3 and 4 positions. The aldehyde reacts with the diamine to an intermediate di-imine (R C=N N=C R), which, with added hydrochloric acid, gives ring-closure and loss of ammonia to the pyrrole CONFIDENCE standard compound; INTERNAL_ID 8155 Flavouring ingredient

Myo-Inositol

C6H12O6 (180.0633852)

myo-Inositol is an inositol isoform. Inositol is a derivative of cyclohexane with six hydroxyl groups, making it a polyol. It also is known as a sugar alcohol, having exactly the same molecular formula as glucose or other hexoses. Inositol exists in nine possible stereoisomers, of which cis-1,2,3,5-trans-4,6-cyclohexanehexol, or myo-inositol is the most widely occurring form in nature. The other known inositols include scyllo-inositol, muco-inositol, D-chiro-inositol, L-chiro-inositol, neo-inositol, allo-inositol, epi-inositol and cis-inositol. myo-Inositol is found naturally in many foods (particularly in cereals with high bran content) and can be used as a sweetner as it has half the sweetness of sucrose (table sugar). myo-Inositol was once considered a member of the vitamin B complex and given the name: vitamin B8. However, because it is produced by the human body from glucose, it is not an essential nutrient, and therefore cannot be called a vitamin. myo-Inositol is a precursor molecule for a number of secondary messengers including various inositol phosphates. In addition, inositol/myo-inositol is an important component of the lipids known as phosphatidylinositol (PI) phosphatidylinositol phosphate (PIP). myo-Inositol is synthesized from glucose, via glucose-6-phosphate (G-6-P) in two steps. First, G-6-P is isomerised by an inositol-3-phosphate synthase enzyme to myo-inositol 1-phosphate, which is then dephosphorylated by an inositol monophosphatase enzyme to give free myo-inositol. In humans, myo-inositol is primarily synthesized in the kidneys at a rate of a few grams per day. myo-Inositol can be used in the management of preterm babies who have or are at a risk of infant respiratory distress syndrome. It is also used as a treatment for polycystic ovary syndrome (PCOS). It works by increasing insulin sensitivity, which helps to improve ovarian function and reduce hyperandrogenism. Reduced levels of myo-inositol have been found in the spinal fluid of depressed patients and levels are significantly reduced in brain samples of suicide victims.

Melibiose

C12H22O11 (342.11620619999997)

Melibiose (CAS: 585-99-9) is a disaccharide consisting of one galactose and one glucose moiety in an alpha (1-6) glycosidic linkage. This sugar is produced and metabolized only by enteric and lactic acid bacteria and other microbes, such as Dickeya dadantii, Escherichia, Leuconostoc, and Saccharomyces (PMID: 19734309, 28453942). It is not an endogenous metabolite but may be obtained from the consumption of partially fermented molasses, brown sugar, or honey. Antibodies to melibiose will appear in individuals affected by Chagas disease (Trypanosoma cruzi infection). Melibiose is not metabolized by humans but can be broken down by gut microflora, such as E. coli. In fact, E. coli is able to utilize melibiose as a sole source of carbon. Melibiose is first imported by the melibiose permease, MelB and then converted into β-D-glucose and β-D-galactose by the α-galactosidase encoded by melA. Because of its poor digestibility, melibiose (along with rhamnose) can be used together for noninvasive intestinal mucosa barrier testing. This test can be used to assess malabsorption or impairment of intestinal permeability. Recent studies with dietary melibiose have shown that it can strongly affect the Th cell responses to an ingested antigen. It has been suggested that melibiose could be used to enhance the induction of oral tolerance (PMID: 17986780). Isomaltose is composed of two glucose units and suitable as a non-cariogenic sucrose replacement and is favorable in products for diabetics and prediabetic dispositions.

Phosphate

H3O4P (97.9768968)

Phosphate is a salt of phosphoric acid and is an essential component of life. Organic phosphates are important in biochemistry, biogeochemistry, and ecology. In biological systems, phosphorus is found as a free phosphate ion in solution and is called inorganic phosphate, to distinguish it from phosphates bound in various phosphate esters. Inorganic phosphate is generally denoted Pi and at physiological (neutral) pH primarily consists of a mixture of HPO2-4 and H2PO-4 ions. Phosphates are most commonly found in the form of adenosine phosphates (AMP, ADP, and ATP) and in DNA and RNA, and can be released by the hydrolysis of ATP or ADP. Similar reactions exist for the other nucleoside diphosphates and triphosphates. Phosphoanhydride bonds in ADP and ATP, or other nucleoside diphosphates and triphosphates, contain high amounts of energy which give them their vital role in all living organisms. Phosphate must be actively transported into cells against its electrochemical gradient. In vertebrates, two unrelated families of Na+-dependent Pi transporters carry out this task. Remarkably, the two families transport different Pi species: whereas type II Na+/Pi cotransporters (SCL34) prefer divalent HPO4(2), type III Na+/Pi cotransporters (SLC20) transport monovalent H2PO4. The SCL34 family comprises both electrogenic and electroneutral members that are expressed in various epithelia and other polarized cells. Through regulated activity in apical membranes of the gut and kidney, they maintain body Pi homeostasis, and in salivary and mammary glands, liver, and testes they play a role in modulating the Pi content of luminal fluids. Phosphate levels in the blood play an important role in hormone signalling and in bone homeostasis. In classical endocrine regulation, low serum phosphate induces the renal production of the secosteroid hormone 1,25-dihydroxyvitamin D3 (1,25(OH)2D3). This active metabolite of vitamin D acts to restore circulating mineral (i.e. phosphate and calcium) levels by increasing absorption in the intestine, reabsorption in the kidney, and mobilization of calcium and phosphate from bone. Thus, chronic renal failure is associated with hyperparathyroidism, which in turn contributes to osteomalacia (softening of the bones). Another complication of chronic renal failure is hyperphosphatemia (low levels of phosphate in the blood). Hyperphosphatemia (excess levels of phosphate in the blood) is a prevalent condition in kidney dialysis patients and is associated with increased risk of mortality. Hypophosphatemia (hungry bone syndrome) has been associated with postoperative electrolyte aberrations and after parathyroidectomy (PMID: 17581921, 11169009, 11039261, 9159312, 17625581). Fibroblast growth factor 23 (FGF-23) has recently been recognized as a key mediator of phosphate homeostasis and its most notable effect is the promotion of phosphate excretion. FGF-23 was discovered to be involved in diseases such as autosomal dominant hypophosphatemic rickets, X-linked hypophosphatemia, and tumour-induced osteomalacia in which phosphate wasting was coupled to inappropriately low levels of 1,25(OH)2D3. FGF-23 is regulated by dietary phosphate in humans. In particular, it was found that phosphate restriction decreased FGF-23, and phosphate loading increased FGF-23. In agriculture, phosphate refers to one of the three primary plant nutrients, and it is a component of fertilizers. In ecological terms, because of its important role in biological systems, phosphate is a highly sought after resource. Consequently, it is often a limiting reagent in environments, and its availability may govern the rate of growth of organisms. Addition of high levels of phosphate to environments and to micro-environments in which it is typically rare can have significant ecological consequences. In the context of pollution, phosphates are a principal component of total dissolved solids, a major indicator of water quality. Dihydrogen phosphate is an inorganic sal... Found in fruit juices. It is used in foods as an acidulant for drinks and candies, pH control agent, buffering agent, flavour enhancer, flavouring agent, sequestrant, stabiliser and thickener, and synergist D001697 - Biomedical and Dental Materials > D003764 - Dental Materials

β-D-Fructose 6-phosphate

C6H13O9P (260.0297178)

Fructose 6-phosphate (F6P) belongs to the class of organic compounds known as hexose phosphates. These are carbohydrate derivatives containing a hexose substituted by one or more phosphate groups. F6P is a derivative of fructose, which has been phosphorylated at the 6-hydroxy group. Fructose 6-phosphate is a fundamental metabolite and exists in all living species, ranging from bacteria to plants to humans. The great majority of glucose is converted to fructose 6-phosphate as part of the glycolytic metabolic pathway (glycolysis). Specifically, F6P is produce is produced by the isomerisation of glucose 6-phosphate via the enzyme phosphoglucose isomerase. F6P is in turn further phosphorylated to fructose-1,6-bisphosphate by the enzyme phosphofructokinase-1. Glycolysis is the metabolic pathway that converts glucose into pyruvic acid. The free energy released in this process is used to form ATP and reduced nicotinamide adenine dinucleotide (NADH). In addition to its key involvement in glycolysis, fructose 6-phosphate can also be biosynthesized from glucosamine 6-phosphate via the enzyme glucosamine-6-phosphate isomerase 1. In addition, fructose 6-phosphate and L-glutamine can be converted into glucosamine 6-phosphate and L-glutamic acid through the action of the enzyme glutamine--fructose-6-phosphate aminotransferase. An important intermediate in the Carbohydrates pathway. The interconversion of glucose-6-phosphate and fructose-6-phosphate, the second step of the Embden-Meyerhof glycolytic pathway, is catalyzed by the enzyme phosphoglucose isomerase (PGI).

2-Oxoadipic acid

C6H8O5 (160.0371718)

2-Oxoadipic acid is produced from lysine in the cytosol of cells via the saccharopine and the pipecolic acid pathways. Catabolites of hydroxylysine and tryptophan enter these pathways as 2-aminoadipic- -semialdehyde and 2-oxoadipate, respectively. In the matrix of mitochondria, 2-oxoadipate is decarboxylated to glutaryl-CoA by the 2-oxoadipate dehydrogenase complex and then converted to acetyl-CoA. 2-Oxoadipic aciduria is an in-born error of metabolism of lysine, tryptophan, and hydroxylysine, in which abnormal quantities of 2-aminoadipic acid are found in body fluids along with 2-oxoadipic acid. Patients with 2-Oxoadipic acidemias are mentally retarded with hypotonia or seizures. 2-Oxoadipic aciduria can occur in patients with Kearns-Sayre Syndrome, a progressive disorder with onset prior to 20 years of age in which multiple organ systems are affected, including progressive external ophthalmoplegia, retinopathy, and the age of onset, and these are associated classically with abnormalities in cardiac conduction, cerebellar signs, and elevated cerebrospinal fluid protein (PMID: 10655159, 16183823, 11083877).

Lumichrome, also known as light folinic acid or 7,8-dimethyl-10-ribitylisoalloxazine, is a derivative of riboflavin (vitamin B2). The chemical structure of lumichrome consists of a heterocyclic isoalloxazine ring, which is a fused pyridine and pyrazine ring system. The isoalloxazine ring contains a methyl group at the 7 and 8 positions and is substituted at the 10 position with a ribityl group, which is a 5-carbon chain derived from ribose with a methyl group at the 2’ position. Photocatalytic Activity: Lumichrome exhibits photocatalytic activity and can act as a photosensitizer. It can absorb light energy and transfer it to other molecules, potentially triggering photochemical reactions. Fluorescence: Lumichrome is known for its fluorescence properties. This characteristic makes it useful in various applications, including fluorescence microscopy and as a labeling agent in biological assays. Antioxidant Properties: Lumichrome has been found to have antioxidant properties. It can scavenge free radicals, which may help in protecting cells from oxidative stress. Metabolic Intermediate: In the body, lumichrome can be formed from riboflavin through photochemical or enzymatic degradation. It may play a role in the metabolism of flavins and could be involved in the recycling of flavin cofactors. Potential Biomarker: Due to its presence in biological tissues and its fluorescence properties, lumichrome has been proposed as a potential biomarker for certain diseases and conditions. Plant Pigment: In plants, lumichrome can be involved in light capture and energy transfer processes, although it is not a chlorophyll pigment. It may contribute to the overall light-harvesting capabilities of plant tissues. While lumichrome has several interesting chemical and biological properties, it is not considered an essential nutrient like its parent compound, riboflavin. Its exact role in biological systems is still an area of ongoing research. Lumichrome, a photodegradation product of Riboflavin, is an endogenous compound in humans. Lumichrome inhibits human lung cancer cell growth and induces apoptosis via a p53-dependent mechanism[1][2].

2-Hydroxybutyric acid

C4H8O3 (104.0473418)

2-Hydroxybutyric acid (CAS: 600-15-7), also known as alpha-hydroxybutyrate, is an organic acid derived from alpha-ketobutyrate. alpha-Ketobutyrate is produced by amino acid catabolism (threonine and methionine) and glutathione anabolism (cysteine formation pathway) and is metabolized into propionyl-CoA and carbon dioxide (PMID: 20526369). 2-Hydroxybutyric acid is formed as a byproduct from the formation of alpha-ketobutyrate via a reaction catalyzed by lactate dehydrogenase (LDH) or alpha-hydroxybutyrate dehydrogenase (alphaHBDH). alpha-Hydroxybutyric acid is primarily produced in mammalian hepatic tissues that catabolize L-threonine or synthesize glutathione. Oxidative stress or detoxification of xenobiotics in the liver can dramatically increase the rate of hepatic glutathione synthesis. Under such metabolic stress conditions, supplies of L-cysteine for glutathione synthesis become limiting, so homocysteine is diverted from the transmethylation pathway (which forms methionine) into the transsulfuration pathway (which forms cystathionine). alpha-Ketobutyrate is released as a byproduct when cystathionine is cleaved into cysteine that is incorporated into glutathione. Chronic shifts in the rate of glutathione synthesis may be reflected by urinary excretion of 2-hydroxybutyrate. 2-Hydroxybutyrate is an early marker for both insulin resistance and impaired glucose regulation that appears to arise due to increased lipid oxidation and oxidative stress (PMID: 20526369). 2-Hydroxybutyric acid is often found in the urine of patients suffering from lactic acidosis and ketoacidosis. 2-Hydroxybutyric acid generally appears at high concentrations in situations related to deficient energy metabolism (e.g. birth asphyxia) and also in inherited metabolic diseases affecting the central nervous system during neonatal development, such as "cerebral" lactic acidosis, glutaric aciduria type II, dihydrolipoyl dehydrogenase (E3) deficiency, and propionic acidemia. More recently it has been noted that elevated levels of alpha-hydroxybutyrate in the plasma is a good marker for early-stage type II diabetes (PMID: 19166731). It was concluded from studies done in the mid-1970s that an increased NADH2/NAD ratio was the most important factor for the production of 2-hydroxybutyric acid (PMID: 168632). 2-Hydroxybutyric acid is an organic acid that is involved in propanoate metabolism.

Delphinidin

[C15H11O7]+ (303.0504756)

Delphinidin, also known as delphinidin chloride (CAS: 528-53-0), belongs to the class of organic compounds known as 7-hydroxyflavonoids. These are flavonoids that bear one hydroxyl group at the C-7 position of the flavonoid skeleton. Thus, delphinidin is considered to be a flavonoid lipid molecule. Delphinidin is found, on average, in the highest concentration within a few different foods, such as bilberries, cowpea, and blackcurrants, and in a lower concentration in common beans, common pea, and wheats. Delphinidin has also been detected, but not quantified in, several different foods, such as Brussel sprouts, fruits, horseradish tree, pepper (C. pubescens), and macadamia nuts. This could make delphinidin a potential biomarker for the consumption of these foods. Delphinidin is an anthocyanin and a primary plant pigment. Delphinidin gives blue hues to flowers like violas and delphiniums. It also gives the blue-red colour of the grape that produces Cabernet Sauvignon, and can be found in cranberries (Wikipedia). BioTransformer predicts that delphinidin is a product of 5,7-dihydroxy-3-{oxy}-2-(3,4,5-trihydroxyphenyl)-1λ⁴-chromen-1-ylium metabolism via a glycoside-hydrolysis reaction occurring in human gut microbiota and catalyzed by an EC.3.2.1.X enzyme (PMID: 30612223). Widespread anthocyanidin found especies in blueberries, raspberries and red table wine. Glycosides also widespread.

Cholesterol

C27H46O (386.3548466)

Cholesterol is a sterol (a combination steroid and alcohol) and a lipid found in the cell membranes of all body tissues and transported in the blood plasma of all animals. The name originates from the Greek chole- (bile) and stereos (solid), and the chemical suffix -ol for an alcohol. This is because researchers first identified cholesterol in solid form in gallstones in 1784. In the body, cholesterol can exist in either the free form or as an ester with a single fatty acid (of 10-20 carbons in length) covalently attached to the hydroxyl group at position 3 of the cholesterol ring. Due to the mechanism of synthesis, plasma cholesterol esters tend to contain relatively high proportions of polyunsaturated fatty acids. Most of the cholesterol consumed as a dietary lipid exists as cholesterol esters. Cholesterol esters have a lower solubility in water than cholesterol and are more hydrophobic. They are hydrolyzed by the pancreatic enzyme cholesterol esterase to produce cholesterol and free fatty acids. Cholesterol has vital structural roles in membranes and in lipid metabolism in general. It is a biosynthetic precursor of bile acids, vitamin D, and steroid hormones (glucocorticoids, estrogens, progesterones, androgens and aldosterone). In addition, it contributes to the development and functioning of the central nervous system, and it has major functions in signal transduction and sperm development. Cholesterol is a ubiquitous component of all animal tissues where much of it is located in the membranes, although it is not evenly distributed. The highest proportion of unesterified cholesterol is in the plasma membrane (roughly 30-50\\\\% of the lipid in the membrane or 60-80\\\\% of the cholesterol in the cell), while mitochondria and the endoplasmic reticulum have very low cholesterol contents. Cholesterol is also enriched in early and recycling endosomes, but not in late endosomes. The brain contains more cholesterol than any other organ where it comprises roughly a quarter of the total free cholesterol in the human body. Of all the organic constituents of blood, only glucose is present in a higher molar concentration than cholesterol. Cholesterol esters appear to be the preferred form for transport in plasma and as a biologically inert storage (de-toxified) form. They do not contribute to membranes but are packed into intracellular lipid particles. Cholesterol molecules (i.e. cholesterol esters) are transported throughout the body via lipoprotein particles. The largest lipoproteins, which primarily transport fats from the intestinal mucosa to the liver, are called chylomicrons. They carry mostly triglyceride fats and cholesterol that are from food, especially internal cholesterol secreted by the liver into the bile. In the liver, chylomicron particles give up triglycerides and some cholesterol. They are then converted into low-density lipoprotein (LDL) particles, which carry triglycerides and cholesterol on to other body cells. In healthy individuals, the LDL particles are large and relatively few in number. In contrast, large numbers of small LDL particles are strongly associated with promoting atheromatous disease within the arteries. (Lack of information on LDL particle number and size is one of the major problems of conventional lipid tests.). In conditions with elevated concentrations of oxidized LDL particles, especially small LDL particles, cholesterol promotes atheroma plaque deposits in the walls of arteries, a condition known as atherosclerosis, which is a major contributor to coronary heart disease and other forms of cardiovascular disease. There is a worldwide trend to believe that lower total cholesterol levels tend to correlate with lower atherosclerosis event rates (though some studies refute this idea). As a result, cholesterol has become a very large focus for the scientific community trying to determine the proper amount of cholesterol needed in a healthy diet. However, the primary association of atherosclerosis with c... Constituent either free or as esters, of fish liver oils, lard, dairy fats, egg yolk and bran Cholesterol is the major sterol in mammals. It is making up 20-25\\% of structural component of the plasma membrane. Plasma membranes are highly permeable to water but relatively impermeable to ions and protons. Cholesterol plays an important role in determining the fluidity and permeability characteristics of the membrane as well as the function of both the transporters and signaling proteins[1][2]. Cholesterol is also an endogenous estrogen-related receptor α (ERRα) agonist[3]. Cholesterol is the major sterol in mammals. It is making up 20-25\% of structural component of the plasma membrane.

Tomatine

C50H83NO21 (1033.5457308)

Tomatine is a mildly toxic glycoalkaloid or glycospirosolane (steroidal alkaloids whose structure contains a spirosolane skeleton) found in the stems and leaves of tomato plants as well as in the fruit of unripened (green) tomatoes (up to 500 mg/kg). Red, ripe tomatoes have somewhat reduced amounts of tomatine. A toxic dose of tomatine for an adult human would appear to require the consumption of at least 500 g of tomato leaves in one sitting (“Toxic Plants of North America” (Iowa State University Press, 2001)). Tomatine is known to have fungicidal and antimicrobial properties and is likely produced by tomato plants as a defense against bacteria, fungi, viruses, and insects (PMID: 19514731). Some microbes produce an enzyme called tomatinase which can degrade tomatine, rendering it ineffective as an antimicrobial (PMID: 18835993).Tomatine has historically been used as a reagent in analytical chemistry for precipitating cholesterol from solution (PMID: 4362143). When lab animals ingest tomatine, essentially all of it passes through the animal unabsorbed. Tomatine apparently binds to cholesterol in the digestive tract, and the largely insoluble combination is excreted — ridding the body of both the alkaloid and cholesterol. Experiments with hamsters have shown that both tomatine-rich green tomatoes and purified tomatine can substantially lower the levels of undesirable LDL cholesterol while maintaining normal levels of HDL (PMID: 10942315). Experiments with high-tomatine green tomato extracts were recently shown to strongly inhibit the growth of a number of human cancer cell lines including breast (MCF-7), colon (HT-29), gastric (AGS), and hepatoma (liver) (HepG2), as well as normal human liver cells (PMID: 19514731). Other studies have found that purified tomatine is an outstanding immunoadjuvant capable of stimulating potent antigen-specific humoral and cellular immune responses that contribute to protection against malaria, Francisella tularensis and regression of experimental tumors (PMID: 15193398).

Benzaldehyde

C7H6O (106.0418626)

Benzaldehyde is occasionally found as a volatile component of urine. Benzaldehyde is an aromatic aldehyde used in cosmetics as a denaturant, a flavoring agent, and as a fragrance. Currently used in only seven cosmetic products, its highest reported concentration of use was 0.5\\\% in perfumes. Benzaldehyde is a generally regarded as safe (GRAS) food additive in the United States and is accepted as a flavoring substance in the European Union. Because Benzaldehyde rapidly metabolizes to Benzoic Acid in the skin, the available dermal irritation and sensitization data demonstrating no adverse reactions to Benzoic Acid were considered supportive of the safety of Benzaldehyde. Benzaldehyde is absorbed through skin and by the lungs, distributes to all well-perfused organs, but does not accumulate in any specific tissue type. After being metabolized to benzoic acid, conjugates are formed with glycine or glucuronic acid, and excreted in the urine. Several studies have suggested that Benzaldehyde can have carcinostatic or antitumor properties. Overall, at the concentrations used in cosmetics, Benzaldehyde was not considered a carcinogenic risk to humans. Although there are limited irritation and sensitization data available for Benzaldehyde, the available dermal irritation and sensitization data and ultraviolet (UV) absorption and phototoxicity data demonstrating no adverse reactions to Benzoic Acid support the safety of Benzaldehyde as currently used in cosmetic products. (PMID:16835129, Int J Toxicol. 2006;25 Suppl 1:11-27.). Benzaldehyde, a volatile organic compound, is naturally present in a variety of plants, particularly in certain fruits, nuts, and flowers. It plays a significant role in the aromatic profiles of these plants. For instance, benzaldehyde is a primary component of bitter almond oil, which was one of its earliest known natural sources. Besides bitter almonds, it is also found in fruits like cherries, peaches, and plums, as well as in flowers such as jasmine. In the food industry, benzaldehyde is occasionally used as a food additive to impart specific flavors. This prevalence in plants highlights that benzaldehyde is not only an industrial chemical but also a naturally occurring compound in the plant kingdom. Its presence in these natural sources underscores its significance in both nature and industry. Found in plants, especies in almond kernelsand is) also present in strawberry jam, leek, crispbread, cheese, black tea and several essential oils. Parent and derivs. (e.g. glyceryl acetal) are used as flavourings

Nicotinic acid adenine dinucleotide

[C21H27N6O15P2]+ (665.1009592)

Nicotinic acid adenine dinucleotide, also known as deamido-NAD or NAAD, belongs to the class of organic compounds known as (5->5)-dinucleotides. These are dinucleotides where the two bases are connected via a (5->5)-phosphodiester linkage. NAAD is possibly soluble (in water) and a strong basic compound (based on its pKa). NAAD exists in all living species, ranging from bacteria to humans. L-Glutamine and NAAD can be converted into L-glutamic acid and NAD; which is catalyzed by the enzyme glutamine-dependent nad(+) synthetase. In humans, NAAD is involved in the nicotinate and nicotinamide metabolism pathway. NAAD is also involved in the metabolic disorder called succinic semialdehyde dehydrogenase deficiency. Outside of the human body, NAAD has been detected, but not quantified in, several different foods, such as japanese walnuts, cauliflowers, sparkleberries, komatsuna, and macadamia nut (m. tetraphylla). This could make NAAD a potential biomarker for the consumption of these foods. NAAD is the product of the degradation of Nicotinic acid adenine dinucleotide phosphate (NAADP) by a Ca2+-sensitive phosphatase. NAADP is a Ca2+-mobilizing second messenger which is synthesized, in response to extracellular stimuli, via the base-exchange reaction by an ADP-ribosyl cyclase (ARC) family members (such as CD38). NAADP binds to and opens Ca2+ channels on intracellular organelles, thereby increasing the intracellular Ca2+ concentration which, in turn, modulates a variety of cellular processes. Structurally, NAADP it is a dinucleotide that only differs from the house-keeping enzyme cofactor, NADP, by a hydroxyl group (replacing the nicotinamide amino group) and yet this minor modification converts it into the most potent Ca2+-mobilizing second messenger yet described. NAADP may also be broken down to 2-phosphoadenosine diphosphoribose (ADPRP) by CD38 or reduced to NAADPH. Deamido-nad(+), also known as deamidonicotinamide adenine dinucleoetide, is a member of the class of compounds known as (5->5)-dinucleotides (5->5)-dinucleotides are dinucleotides where the two bases are connected via a (5->5)-phosphodiester linkage. Deamido-nad(+) is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Deamido-nad(+) can be found in a number of food items such as garden tomato, sea-buckthornberry, pitanga, and japanese walnut, which makes deamido-nad(+) a potential biomarker for the consumption of these food products. Deamido-nad(+) exists in all living species, ranging from bacteria to humans. In humans, deamido-nad(+) is involved in few metabolic pathways, which include glutamate metabolism, homocarnosinosis, and nicotinate and nicotinamide metabolism. Deamido-nad(+) is also involved in few metabolic disorders, which include 2-hydroxyglutric aciduria (D and L form), 4-hydroxybutyric aciduria/succinic semialdehyde dehydrogenase deficiency, hyperinsulinism-hyperammonemia syndrome, and succinic semialdehyde dehydrogenase deficiency.

Pelargonidin

[C15H11O5]+ (271.0606456)

Pelargonidin, also known as pelargonidin chloride (CAS: 134-04-3) is an anthocyanin. Anthocyanins are water-soluble glycosides and acylglycosides of anthocyanidins, which are polyhydroxy and polymethoxyl derivatives of a 2-phenylbenzopyrylium (flavylium) cation. They are widely distributed in foods of plant origin, especially in fruits and vegetables with dark red and blue colours. Numerous epidemiologic and clinical trials show that fruits and vegetables, many of which are rich in anthocyanins, may be related to the decreased incidence of many chronic and degenerative diseases, including heart disease, cancer, and aging. Antioxidant mechanisms were suggested as potential means of disease prevention. Anthocyanins are strong antioxidants in vitro. In most cases, fruits and vegetables with high anthocyanin content were shown to have higher antioxidant capacity than other fruits and vegetables. Whether anthocyanins are effective antioxidants in vivo remains an open question primarily because of the relatively low apparent absorption of anthocyanins compared with other phenolic compounds (PMID: 15465754). BioTransformer predicts that pelargonidin is a product of 5-[(6-{[(2-carboxyacetyl)oxy]methyl}-3,4,5-trihydroxyoxan-2-yl)oxy]-3,7-dihydroxy-2-(4-hydroxyphenyl)-1λ⁴-chromen-1-ylium metabolism via a glycoside-hydrolysis reaction occurring in human gut microbiota and catalyzed by an EC.3.2.1.X enzyme (PMID: 30612223). Anthocyanin pigment present in many plants, flowers and fruits, e.g. cherries, raspberries, radishes, orchids, brassicas, Petunia subspecies Glycosides also widely distributed. Pelargonidin is found in many foods, some of which are almond, radish (variety), garden tomato, and tarragon.

Retinol(Vitamin A)

C20H30O (286.229653)

Vitamin A (retinol) is a yellow fat-soluble, antioxidant vitamin important in vision and bone growth. It belongs to the family of chemical compounds known as retinoids. Retinol is ingested in a precursor form; animal sources (milk and eggs) contain retinyl esters, whereas plants (carrots, spinach) contain pro-vitamin A carotenoids. Hydrolysis of retinyl esters results in retinol while pro-vitamin A carotenoids can be cleaved to produce retinal. Retinal, also known as retinaldehyde, can be reversibly reduced to produce retinol or it can be irreversibly oxidized to produce retinoic acid. Retinol and derivatives of retinol that play an essential role in metabolic functioning of the retina, the growth of and differentiation of epithelial tissue, the growth of bone, reproduction, and the immune response. Dietary vitamin A is derived from a variety of carotenoids found in plants. It is enriched in the liver, egg yolks, and the fat component of dairy products. Retinyl esters from animal-sourced foods (or synthesized for dietary supplements for humans and domesticated animals) are acted upon by retinyl ester hydrolases in the lumen of the small intestine to release free retinol. Retinol enters intestinal absorptive cells by passive diffusion. Absorption efficiency is in the range of 70 to 90\%. Humans are at risk for acute or chronic vitamin A toxicity because there are no mechanisms to suppress absorption or excrete the excess in urine.[5] Within the cell, retinol is there bound to retinol binding protein 2 (RBP2). It is then enzymatically re-esterified by the action of lecithin retinol acyltransferase and incorporated into chylomicrons that are secreted into the lymphatic system. Unlike retinol, β-carotene is taken up by enterocytes by the membrane transporter protein scavenger receptor B1 (SCARB1). The protein is upregulated in times of vitamin A deficiency. If vitamin A status is in the normal range, SCARB1 is downregulated, reducing absorption.[6] Also downregulated is the enzyme beta-carotene 15,15'-dioxygenase (formerly known as beta-carotene 15,15'-monooxygenase) coded for by the BCMO1 gene, responsible for symmetrically cleaving β-carotene into retinal.[8] Absorbed β-carotene is either incorporated as such into chylomicrons or first converted to retinal and then retinol, bound to RBP2. After a meal, roughly two-thirds of the chylomicrons are taken up by the liver with the remainder delivered to peripheral tissues. Peripheral tissues also can convert chylomicron β-carotene to retinol.[6][15] The capacity to store retinol in the liver means that well-nourished humans can go months on a vitamin A deficient diet without manifesting signs and symptoms of deficiency. Two liver cell types are responsible for storage and release: hepatocytes and hepatic stellate cells (HSCs). Hepatocytes take up the lipid-rich chylomicrons, bind retinol to retinol-binding protein 4 (RBP4), and transfer the retinol-RBP4 to HSCs for storage in lipid droplets as retinyl esters. Mobilization reverses the process: retinyl ester hydrolase releases free retinol which is transferred to hepatocytes, bound to RBP4, and put into blood circulation. Other than either after a meal or when consumption of large amounts exceeds liver storage capacity, more than 95\% of retinol in circulation is bound to RBP4.[15] Vitamin A is a fat-soluble vitamin, hence an essential nutrient. The term "vitamin A" encompasses a group of chemically related organic compounds that includes retinol, retinal (also known as retinaldehyde), retinoic acid, and several provitamin (precursor) carotenoids, most notably beta-carotene.[3][4][5][6] Vitamin A has multiple functions: essential in embryo development for growth, maintaining the immune system, and healthy vision, where it combines with the protein opsin to form rhodopsin – the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision.[7] Vitamin A occurs as two principal forms in foods: A) retinol, found in animal-sourced foods, either as retinol or bound to a fatty acid to become a retinyl ester, and B) the carotenoids alpha-carotene, β-carotene, gamma-carotene, and the xanthophyll beta-cryptoxanthin (all of which contain β-ionone rings) that function as provitamin A in herbivore and omnivore animals which possess the enzymes that cleave and convert provitamin carotenoids to retinal and then to retinol.[8] Some carnivore species lack this enzyme. The other carotenoids have no vitamin activity.[6] Dietary retinol is absorbed from the digestive tract via passive diffusion. Unlike retinol, β-carotene is taken up by enterocytes by the membrane transporter protein scavenger receptor B1 (SCARB1), which is upregulated in times of vitamin A deficiency.[6] Storage of retinol is in lipid droplets in the liver. A high capacity for long-term storage of retinol means that well-nourished humans can go months on a vitamin A- and β-carotene-deficient diet, while maintaining blood levels in the normal range.[4] Only when the liver stores are nearly depleted will signs and symptoms of deficiency show.[4] Retinol is reversibly converted to retinal, then irreversibly to retinoic acid, which activates hundreds of genes.[9] Vitamin A deficiency is common in developing countries, especially in Sub-Saharan Africa and Southeast Asia. Deficiency can occur at any age but is most common in pre-school age children and pregnant women, the latter due to a need to transfer retinol to the fetus. Vitamin A deficiency is estimated to affect approximately one-third of children under the age of five around the world, resulting in hundreds of thousands of cases of blindness and deaths from childhood diseases because of immune system failure.[10] Reversible night blindness is an early indicator of low vitamin A status. Plasma retinol is used as a biomarker to confirm vitamin A deficiency. Breast milk retinol can indicate a deficiency in nursing mothers. Neither of these measures indicates the status of liver reserves.[6] The European Union and various countries have set recommendations for dietary intake, and upper limits for safe intake. Vitamin A toxicity also referred to as hypervitaminosis A, occurs when there is too much vitamin A accumulating in the body. Symptoms may include nervous system effects, liver abnormalities, fatigue, muscle weakness, bone and skin changes, and others. The adverse effects of both acute and chronic toxicity are reversed after consumption of high dose supplements is stopped.[6]

Aminomalonic acid

C3H5NO4 (119.02185700000001)

Aminomalonic acid (Ama) is an amino dicarboxylic acid that is an analog of malonic acid in which one of the methylene hydrogens has been replaced by an amino group. It is a strongly acidic compound that is very water soluble. Aminomalonic acid is a natural occurring, largely non-proteogenic amino acid that was first detected in alkaline hydrolysates of proteins in 1984. In particular, aminomalonic acid was isolated from proteins isolated from Escherichia coli cultures and from human atherosclerotic plaques (PMID: 6366787). Aminomalonic acid is a relatively unstable, minor amino acid in complex structures such as bacteria or tissues. The presence of aminomalonic acid has important biological implications because the malonic acid moiety potentially imparts calcium binding properties to proteins. Possible origins of aminomalonic acid in proteins include its introduction via errors in protein synthesis and oxidative damage to amino acid residues in proteins. (PMID: 1621954 , 6366787 ). Aminomalonic acid can be generated naturally via the activity of mammalian and bacterial enzymes on various precursors such as 2-aminomalonamide, diethylaminomalonate and ketomalonic acid (PMID: 35346). Free aminomalonic acid appears to be an oxidation product arising from perturbed serine or threonine metabolism. Aminomalonic acid is produced in animals that have been exposed to Cadmium (a strong pro-oxidant) for extended periods of time and it has been proposed to be a potential biomarker of Cadmium toxicity (PMID: 32193438). Aminomalonic acid has also been found to be elevated in the urine of individuals with anxiety and major depressive disorders (PMID: 30232320). Aminomalonic acid has been reported to be a potential biomarker for hepatocellular carcinoma (PMID: 18767022) and it exhibits strong inhibitory effects on L-asparagine synthase (PMID: 35346). Several metabolomics studies have also found that altered aminomalonic acid levels in serum are associated with neuropsychiatric disorders, melanoma, ketamine overdose and aortic aneurysm, indicating that aminomalonic acid is an important serum indicator for diseases and toxicities (PMID: 32193438). Aminomalonic acid (Ama) was first detected in alkaline hydrolysates of proteins in 1984. Ama has been isolated from proteins of Escherichia coli and human atherosclerotic plaque. The presence of Ama has important biological implications because the malonic acid moiety potentially imparts calcium binding properties to protein. Ama is not formed from any of the 20 major amino acids during the hydrolysis procedure. Furthermore, the amount of Ama found does not depend on the presence of small amounts of O2 during the hydrolysis. No artifactual formation of ama has been demonstrated and may indeed be a constituent of proteins before the hydrolysis procedure. Possible origins of Ama include errors in protein synthesis and oxidative damage to amino acid residues in proteins. (PMID: 1621954, 6366787) [HMDB] Aminomalonic acid is an amino endogenous metabolite, acts as a strong inhibitor of L-asparagine synthetase from Leukemia 5178Y/AR (Ki= 0.0023 M) and mouse pancreas (Ki= 0.0015 M) in vitro. Aminomalonic acid is a potential biomarker to discriminate between different stages of melanoma metastasis[1][2][3].

Glucose

C6H12O6 (180.0633852)

D-Galactose (CAS: 59-23-4) is an aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. D-Galactose is an energy-providing nutrient and also a necessary basic substrate for the biosynthesis of many macromolecules in the body. Metabolic pathways for D-galactose are important not only for the provision of these pathways but also for the prevention of D-galactose metabolite accumulation. The main source of D-galactose is lactose in the milk of mammals, but it can also be found in some fruits and vegetables. Utilization of D-galactose in all living cells is initiated by the phosphorylation of the hexose by the enzyme galactokinase (E.C. 2.7.1.6) (GALK) to form D-galactose-1-phosphate. In the presence of D-galactose-1-phosphate uridyltransferase (E.C. 2.7.7.12) (GALT) D-galactose-1-phosphate is exchanged with glucose-1-phosphate in UDP-glucose to form UDP-galactose. Glucose-1-phosphate will then enter the glycolytic pathway for energy production. Deficiency of the enzyme GALT in galactosemic patients leads to the accumulation of D-galactose-1-phosphate. Classic galactosemia, a term that denotes the presence of D-galactose in the blood, is the rare inborn error of D-galactose metabolism, diagnosed by the deficiency of the second enzyme of the D-galactose assimilation pathway, GALT, which, in turn, is caused by mutations at the GALT gene (PMID: 15256214, 11020650, 10408771). Galactose in the urine is a biomarker for the consumption of milk.

L-Fucose

C6H12O5 (164.0684702)

Fucose (CAS: 2438-80-4) is a hexose deoxy sugar with the chemical formula C6H12O5. L-Fucose (6-deoxy-L-galactose) is a monosaccharide that is a common component of many N- and O-linked glycans and glycolipids produced by mammalian cells. It is the fundamental subunit of the fucoidan polysaccharide. As a free sugar, L-fucose is normally found at very low levels in mammals. It is unique in that it is the only levorotatory sugar synthesized and utilized by mammals. Fucose polymers are synthesized by fucosyltransferases. All fucosyltransferases utilize a nucleotide-activated form of fucose, GDP-fucose, as a fucose donor in the construction of fucosylated oligosaccharides. The ABO blood group antigens are among the most well known fucosylated glycans. The alpha-1->3 linked core fucose is a suspected carbohydrate antigen for IgE-mediated allergy. Two structural features distinguish fucose from other six-carbon sugars present in mammals: the lack of a hydroxyl group on the carbon at the 6-position (C-6) and the L-configuration. In fucose-containing glycan structures, fucosylated glycans, fucose can exist as a terminal modification or serve as an attachment point for adding other sugars. Fucose is metabolized by an enzyme called alpha-fucosidase. Fucose is secreted in urine when the liver is damaged. Free L-fucose in serum and urine can be used as a marker for cancer, cirrhosis, alcoholic liver disease and gastric ulcers (PMID: 2311216, 8488966). Elevated levels of serum fucose have been reported in breast cancer, ovarian cancer, lung cancer, liver cancer, diabetes, and cardiovascular disease. It has been shown that feeding rats a diet high in L-fucose induces neuropathy similar to that seen in diabetics.

All animals and plants dynamically attach and remove beta-N-acetylglucosamine at serine and threonine residues on myriad nuclear and cytoplasmic proteins. beta-N-Acetylglucosamine cycling, which is tightly regulated by the concerted actions of two highly-conserved enzymes, serves as a nutrient and stress sensor. Proteins glycosylated with beta-N-acetylglucosamine can be found in almost every intracellular compartment and almost every functional class (PMID: 17460662).

D-Xylulose-5-phosphate

C5H11O8P (230.0191536)

Xylulose 5-phosphate (Xu-5-P) is a metabolite of the hexose monophosphate pathway that activates protein phosphatase 2A to mediate the acute effects of carbohydrate feeding on the glycolytic pathway, as well as the coordinate long-term control of the enzymes required for fatty acid and triglyceride synthesis. Xu-5-P is the signal for the coordinated control of lipogenesis. Feeding carbohydrate causes levels of liver glucose, Glucose-6-phosphate (Glc-6-P), and Fructose-6-phosphate (Fru-6-P) to rise. Elevation of Fru-6-P leads to elevation of Xu-5-P in reactions catalyzed by the near-equilibrium isomerases of the nonoxidative portion of the hexose monophosphate pathway (ribulose 5-phosphate (Ru5P) epimerase [EC 5.1.3.1], ribose 5-phosphate (Rib5P) isomerase [EC 5.3.1.6], transaldolase [EC 2.2.1.2], and transketolase [EC 2.2.1.1]). The elevation of Xu-5-P is the coordinating signal that both acutely activates phosphofructokinase [PFK; EC 2.7.1.11] in glycolysis and promotes the action of the transcription factor carbohydrate responsive element binding protein (ChREBP) to increase transcription of the genes for the enzymes of lipogenesis, the hexose monophosphate shunt, and glycolysis, all of which are required for the de novo synthesis of fat.

Tartaric acid

C4H6O6 (150.0164376)

Tartaric acid is a white crystalline organic acid. It occurs naturally in many plants, particularly grapes and tamarinds, and is one of the main acids found in wine. It is added to other foods to give a sour taste, and is used as an antioxidant. Salts of tartaric acid are known as tartrates. It is a dihydroxy derivative of dicarboxylic acid. Tartaric acid is a muscle toxin, which works by inhibiting the production of malic acid, and in high doses causes paralysis and death. The minimum recorded fatal dose for a human is about 12 grams. In spite of that, it is included in many foods, especially sour-tasting sweets. As a food additive, tartaric acid is used as an antioxidant with E number E334, tartrates are other additives serving as antioxidants or emulsifiers. Naturally-occurring tartaric acid is chiral, meaning that it has molecules that are non-superimposable on their mirror-images. It is a useful raw material in organic chemistry for the synthesis of other chiral molecules. The naturally occurring form of the acid is L-(+)-tartaric acid or dextrotartaric acid. The mirror-image (enantiomeric) form, levotartaric acid or D-(-)-tartaric acid, and the achiral form, mesotartaric acid, can be made artificially. Tartarate is believed to play a role in inhibiting kidney stone formation. Most tartarate that is consumed by humans is metabolized by bacteria in the gastrointestinal tract -- primarily in the large instestine. Only about 15-20\\\\\\% of consumed tartaric acid is secreted in the urine unchanged. Tartaric acid is a biomarker for the consumption of wine and grapes (PMID:24507823). Tartaric acid is also a fungal metabolite, elevated levels in the urine (especially in children) may be due to the presence of yeast (in the gut or bladder). It can be produced by Agrobacterium, Nocardia, Rhizobium, Saccharomyces as well (PMID:7628083) (https://link.springer.com/article/10.1023/A:1005592104426). High levels of tartaric acid have been found in autistic children. In adults, tartaric acid may be due to the consumption of wine (https://www.greatplainslaboratory.com/articles-1/2015/11/13/candida-and-overgrowth-the-problem-bacteria-by-products) (PMID:15738524; PMID:24507823; PMID:7628083).

Pyrocatechol

C6H6O2 (110.0367776)

Pyrocatechol, often known as catechol or benzene-1,2-diol, is a benzenediol, with formula C6H4(OH)2. It was first prepared in 1839 by H. Reinsch by distilling catechin (the juice of Mimosa catechu). This colourless compound occurs naturally, but about 20000 tons are manufactured each year, mainly as precursors to pesticides, flavors, and fragrances. Its sulfonic acid is often present in the urine of many mammals. Small amounts of catechol occur naturally in fruits and vegetables, along with the enzyme polyphenol oxidase. Upon mixing the enzyme with the substrate and exposure to oxygen (as when a potato or apple is cut), the colorless catechol oxidizes to reddish-brown benzoquinone derivatives. The enzyme is inactivated by adding an acid, such as lemon juice, or by refrigeration. Excluding oxygen also prevents the browning reaction. Catechol melts at 28 °C and boils at 250 °C. It is employed in medicine as an expectorant. The dimethyl ether or veratrol is also used in medicine. Many other pyrocatechin derivatives have been suggested for therapeutic application. Pyrocatechol has also been found to be a microbial metabolite in Escherichia, Mycobacterium and Pseudomonas (PMID:19300498; PMID:25281236).

L-Arabitol, also known as L-arabinitol or L-lyxitol, is a member of the class of compounds known as sugar alcohols. Sugar alcohols are hydrogenated forms of carbohydrate in which the carbonyl group (aldehyde or ketone reducing sugar) has been reduced to a primary or secondary hydroxyl group. L-Arabitol is soluble in water. L-Arabitol can be found in a number of food items such as sweet potato, deerberry, moth bean, and European chestnut, which makes L-arabitol a potential biomarker for the consumption of these food products. L-Arabitol can be found in most biofluids, including urine, cerebrospinal fluid (CSF), saliva, and blood. L-Arabitol exists in all living species, ranging from bacteria to humans. Moreover, L-arabitol is found to be associated with Alzheimers disease and ribose-5-phosphate isomerase deficiency, which is an inborn error of metabolism.

7-Methylxanthine

C6H6N4O2 (166.0490736)

7-Methylxanthine is a methyl derivative of xanthine, found occasionally in human urine. 7-Methylxanthine is one of the purine components in urinary calculi. Methylated purines originate from the metabolism of methylxanthines (caffeine, theophylline and theobromine). Caffeine is metabolized via successive pathways mainly catalyzed by CYP1A2, xanthine oxidase or N-acetyltransferase-2 to give 14 different metabolites, including 7-methylxanthine. CYP1A2 activity shows an inter-individual variability among the population. CYP1A2, an isoform of the CYP1A cytochrome P450 super-family, is involved in the metabolism of many drugs and plays a potentially important role in the induction of chemical carcinogenesis. Purine derivatives in urinary calculi could be considered markers of abnormal purine metabolism. The content of a purine derivative in stone depends on its average urinary excretion in the general population, similarity to the chemical structure of uric acid, and content of the latter in stone. This suggests that purines in stones represent a solid solution with uric acid as solvent. It is also plausible that methylxanthines, ubiquitous components of the diet and drugs, are involved in the pathogenesis of urolithiasis. (PMID:11712316, 15833286, 3506820, 15013152).

D-Glutamic acid

C5H9NO4 (147.0531554)

There are two forms of glutamic acid found in nature: L-glutamic acid and D-glutamic acid. D-glutamic acid, is not endogenously produced in higher mammals. It is found naturally primarily in the cell walls of certain bacteria. D-glutamate is also present in certain foods e.g., soybeans and also arises from the turnover of the intestinal tract microflora, whose cell walls contain significant D-glutamate. Unlike other D-amino acids, D-glutamate is not oxidized by the D-amino acid oxidases, and therefore this detoxification pathway is not available for handling D-glutamate. Likewise, D-glutamic acid, when ingested, largely escapes most deamination reactions (unlike the L-counterpart). Free D-glutamate is found in mammalian tissue at surprisingly high levels, with D-glutamate accounting for 9\\% of the total glutamate present in liver. D-glutamate is the most potent natural inhibitor of glutathione synthesis identified to date and this may account for its localization to the liver, since circulating D-glutamate may alter redox stabiity (PMID 11158923). Certain eels are known to use D-glutamic acid as a phermone for chemical communication. D-Glutamic acid has been found to be a metabolite of Lactobacillus (PMID: 22754309).

(+)-Nicotine

C10H14N2 (162.1156924)

Chemical Structure of (+)-Nicotine: (+)-Nicotine, also known as d-nicotine, has a complex chemical structure that consists of a pyridine ring with a methyl group at position 3 and a pyrrolidine ring at position 2. The molecular formula of nicotine is C10H14N2. The presence of a nitrogen-containing pyridine ring and a pyrrolidine ring makes nicotine a type of alkaloid. The (+) sign indicates that this is the dextrorotatory isomer, meaning it rotates plane-polarized light to the right. The chemical structure can be described as follows: A six-membered pyridine ring, which is a nitrogen-containing aromatic heterocycle. A methyl group (-CH3) attached to the pyridine ring at the 3-position. A five-membered pyrrolidine ring, which is a saturated nitrogen-containing heterocycle, fused to the pyridine ring at the 2-position. The pyrrolidine ring contains a secondary amine group (-NH-), which is part of the ring structure. Biological Functions of (+)-Nicotine: Neurotransmitter Mimic: (+)-Nicotine acts as an agonist at nicotinic acetylcholine receptors (nAChRs), which are ligand-gated ion channels found in both the central and peripheral nervous systems. By binding to these receptors, nicotine mimics the action of the neurotransmitter acetylcholine, leading to the release of various neurotransmitters and hormones. Central Nervous System Stimulation: When (+)-nicotine binds to nAChRs in the brain, it can increase the release of dopamine, a neurotransmitter associated with reward and pleasure. This effect contributes to the addictive properties of nicotine. Cardiovascular Effects: (+)-Nicotine can have various effects on the cardiovascular system, including increasing heart rate and blood pressure due to the stimulation of nAChRs on adrenergic neurons, which leads to the release of catecholamines (e.g., adrenaline). Metabolic Effects: Nicotine can increase metabolic rate and decrease appetite, which can lead to weight loss in some individuals. Insecticide: (+)-Nicotine has insecticidal properties and has been used historically as a pesticide. It acts by binding to nAChRs in insects, causing paralysis and death. Therapeutic Uses: (+)-Nicotine is used in nicotine replacement therapies (NRT), such as patches, gum, lozenges, and inhalers, to help smokers reduce withdrawal symptoms and quit smoking. It is also being investigated for its potential therapeutic effects in neurological disorders like Alzheimer’s disease and Parkinson’s disease. Toxicity: At high doses, (+)-nicotine can be toxic, leading to nausea, vomiting, dizziness, and in severe cases, respiratory failure and death due to its paralytic effects on the respiratory center. (+)-Nicotine, also known as nikotin or L-nicotine, belongs to the class of organic compounds known as pyrrolidinylpyridines. Pyrrolidinylpyridines are compounds containing a pyrrolidinylpyridine ring system, which consists of a pyrrolidine ring linked to a pyridine ring (+)-Nicotine is a primary metabolite.

Leucine is an α-amino acid, meaning it contains an α-amino group (which is in the protonated −NH3+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain isobutyl group, making it a non-polar aliphatic amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet. Human dietary sources are foods that contain protein, such as meats, dairy products, soy products, and beans and other legumes. It is encoded by the codons UUA, UUG, CUU, CUC, CUA, and CUG. Leucine is named after the Greek word for "white": λευκός (leukós, "white"), after its common appearance as a white powder, a property it shares with many other amino acids.[4] Like valine and isoleucine, leucine is a branched-chain amino acid. The primary metabolic end products of leucine metabolism are acetyl-CoA and acetoacetate; consequently, it is one of the two exclusively ketogenic amino acids, with lysine being the other.[5] It is the most important ketogenic amino acid in humans.[6] Leucine and β-hydroxy β-methylbutyric acid, a minor leucine metabolite, exhibit pharmacological activity in humans and have been demonstrated to promote protein biosynthesis via the phosphorylation of the mechanistic target of rapamycin (mTOR).[7][8] L-Leucine is an essential branched-chain amino acid (BCAA), which activates the mTOR signaling pathway[1].
