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...

Naringin, also known as naringoside or naringin hydrate, is a flavanone-7-O-glycoside between the flavanone naringenin and the disaccharide neohesperidose. Naringin belongs to the flavonoid family. Flavonoids consist of 15 carbon atoms in 3 rings, 2 of which must be benzene rings connected by a 3 carbon chain. Naringin contains the basic flavonoid structure along with one rhamnose and one glucose unit attached to its aglycone portion, called naringenin, at the 7-carbon position. The steric hindrance provided by the two sugar units makes naringin less potent than its aglycone counterpart, naringenin. Naringin is a bitter tasting compound. Naringin is found, on average, in the highest concentration within a few different foods, such as rosemaries, grapefruit/pummelo hybrids, and grapefruits and in a lower concentration in grape wines, pummelo, and beers. Naringin has also been detected, but not quantified in several different foods, such as citrus, limes, herbs and spices, common oregano, and mandarin orange (clementine, tangerine). Both naringin and hesperetin, which are the aglycones of naringin and hesperidin, occur naturally in citrus fruits. Naringin is the major flavonoid glycoside in grapefruit and gives grapefruit juice its bitter taste. Narinigin exerts a variety of pharmacological effects such as antioxidant activity, blood lipid-lowering, anticarcinogenic activity, and inhibition of selected cytochrome P450 enzymes including CYP3A4 and CYP1A2, which may result in several drug interactions in-vitro.

C4H6N4O3 (158.044)

Allantoin is an imidazolidine-2,4-dione that is 5-aminohydantoin in which a carbamoyl group is attached to the exocyclic nitrogen. It has a role as a vulnerary, a human metabolite, a Saccharomyces cerevisiae metabolite and an Escherichia coli metabolite. It is a member of ureas and an imidazolidine-2,4-dione. It is functionally related to a hydantoin. It is a tautomer of a 1-(5-hydroxy-2-oxo-2,3-dihydroimidazol-4-yl)urea. Allantoin is a substance that is endogenous to the human body and also found as a normal component of human diets. In healthy human volunteers, the mean plasma concentration of allantoin is about 2-3 mg/l. During exercise, the plasma allantoin concentration rapidly increases about two fold and remains elevated. In human muscle, urate is oxidized to allantoin during such exercise. The concentration of allantoin in muscles increases from a resting value of about 5000 ug/kg to about 16000 ug/kg immediately after short-term exhaustive cycling exercise. More specifically, allantoin is a diureide of glyoxylic acid that is produced from uric acid. It is a major metabolic intermediate in most organisms. Allantoin is found in OTC cosmetic products and other commercial products such as oral hygiene products, in shampoos, lipsticks, anti-acne products, sun care products, and clarifying lotions. Allantoin has also demonstrated to ameliorate the wound healing process in some studies. Allantoin is a metabolite found in or produced by Escherichia coli (strain K12, MG1655).

Capsaicin

(E)-N-[(4-hydroxy-3-methoxyphenyl)methyl]-8-methylnon-6-enamide

C18H27NO3 (305.1991)

Capsaicin is a capsaicinoid. It has a role as a non-narcotic analgesic, a voltage-gated sodium channel blocker and a TRPV1 agonist. Capsaicin is most often used as a topical analgesic and exists in many formulations of cream, liquid, and patch preparations of various strengths; however, it may also be found in some dietary supplements. Capsaicin is a naturally-occurring botanical irritant in chili peppers, synthetically derived for pharmaceutical formulations. The most recent capsaicin FDA approval was Qutenza, an 8\\\\\\% capsaicin patch dermal-delivery system, indicated for neuropathic pain associated with post-herpetic neuralgia. Capsaicin is a natural product found in Capsicum pubescens, Capsicum, and Capsicum annuum with data available. Capsaicin is a chili pepper extract with analgesic properties. Capsaicin is a neuropeptide releasing agent selective for primary sensory peripheral neurons. Used topically, capsaicin aids in controlling peripheral nerve pain. This agent has been used experimentally to manipulate substance P and other tachykinins. In addition, capsaicin may be useful in controlling chemotherapy- and radiotherapy-induced mucositis. Capsaicin is identified as the primary pungent principle in Capsicum fruits. Hot chili peppers that belong to the plant genus Capsicum (family Solanaceae) are among the most heavily consumed spices throughout the world. The capsaicin content of green and red peppers ranges from 0.1 to 1\\\\\\%. 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. Although a minute amount of capsaicin displays few or no deleterious effects, heavy ingestion of the compound has been associated with necrosis, ulceration and even carcinogenesis. Capsaicin is considered to be metabolized by cytochrome P-450-dependent mixed-function oxidases to reactive species. (A7835). An alkylamide found in CAPSICUM that acts at TRPV CATION CHANNELS.

L-Tyrosine

(2S)-2-amino-3-(4-hydroxyphenyl)propanoic acid

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 (‚ÄìNH2) and carboxyl (‚ÄìCOOH) 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 ‚Äì 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.

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).

Chlorogenic acid is the major polyphenolic compound in coffee, isolated from the leaves and fruits of dicotyledonous plants. This compound, long known as an antioxidant, also slows the release of glucose into the bloodstream after a meal. Coffee is a complex mixture of chemicals that provides significant amounts of chlorogenic acid. The chlorogenic acid content of a 200 ml (7-oz) cup of coffee has been reported to range from 70-350 mg, which would provide about 35-175 mg of caffeic acid. The results of epidemiological research suggest that coffee consumption may help prevent several chronic diseases, including type 2 diabetes mellitus, Parkinsons disease and liver disease (cirrhosis and hepatocellular carcinoma). Most prospective cohort studies have not found coffee consumption to be associated with significantly increased cardiovascular disease risk. However, coffee consumption is associated with increases in several cardiovascular disease risk factors, including blood pressure and plasma homocysteine. At present, there is little evidence that coffee consumption increases the risk of cancer. (PMID:16507475, 17368041).

L-Proline

pyrrolidine-2-carboxylic acid

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 (‚ÄìNH2) and carboxyl (‚ÄìCOOH) 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.

L-Canaline

L-alpha-amino-gamma-(aminooxy)-n-butyric acid

C4H10N2O3 (134.0691)

L-canaline, also known as L-2-amino-4-(aminooxy)butyric acid, 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-canaline is soluble (in water) and a moderately acidic compound (based on its pKa). L-canaline can be found in a number of food items such as mulberry, rape, grape, and black chokeberry, which makes L-canaline a potential biomarker for the consumption of these food products. L-canaline is a substrate for ornithine aminotransferase resulting in the synthesis of L-ureidohomoserine (the corresponding analog of L-citrulline). In turn, the latter forms L-canavaninosuccinic acid in a reaction mediated by argininosuccinic acid synthetase. L-Canavaninosuccinic acid is cleaved to form L-canavanine by argininosuccinic acid synthetase. By these sequential reactions, the canaline-urea cycle (analogous to the ornithine-urea cycle) is formed. Every time a canavanine molecule runs through the canaline-urea cycle, the two terminal nitrogen atoms are released as urea. Urea is an important by-product of this reaction sequence because it makes ammonicial ammonia (urease-mediated) that is available to support intermediary nitrogen metabolism. L-canaline can by reductively cleaved to L-homoserine, a non-protein amino acid of great importance in the formation of a host of essential amino acids. In this way, the third nitrogen atom of canavanine enters into the reactions of nitrogen metabolism of the plant. As homoserine, its carbon skeleton also finds an important use . L-canaline is a non-proteinogenic L-alpha-amino acid that is L-homoserine in which the hydroxy group at position 4 is substituted by an aminooxy group. It has been isolated from legumes and plays an essential role in lugume chemical defense against insects. It has a role as a plant metabolite, an antineoplastic agent, an antimetabolite and a phytogenic insecticide. It is functionally related to a L-homoserine. It is a tautomer of a L-canaline zwitterion. Canavanine reacts with water to produce L-canaline and urea. The reaction is catalyzed by arginase. L-canaline reacts with carbamoyl-phosphate to produce O-ureidohomoserine and phosphate. The reaction is catalyzed by ornithine carbamoyltransferase. A non-proteinogenic L-alpha-amino acid that is L-homoserine in which the hydroxy group at position 4 is substituted by an aminooxy group. It has been isolated from legumes and plays an essential role in lugume chemical defense against insects.

Selenomethionine

2-amino-4-methylselanylbutanoic acid

C5H11NO2Se (196.9955)

L-selenomethionine is the L-enantiomer of selenomethionine. It is an enantiomer of a D-selenomethionine. It is a tautomer of a L-selenomethionine zwitterion. Selenomethionine is a naturally occuring amino acid in some plant materials such as cereal grains, soybeans and enriched yeast but it cannot be synthesized from animals or humans. It can be produced from post-structural modifications. *In vivo*, selenomethionine plays an essential role in acting as an antioxidant, where it depletes reactive oxygen species (ROS) and aids in the formation and recycling of glutathione, another important antioxidant. In comparison to selenite, which is the inorganic form of selenium, the organic form of selenomethionine is more readily absorbed in the human body. Selenomethionin is used in biochemical laboratories where its incorporation into proteins that need to be visualized enhances the performance of X-ray crystallography. L-Selenomethionine is the amino acid methionine with selenium substituting for the sulphur moiety. Methionine is an essential amino acid in humans, whereas selenium is a free-radical scavenging anti-oxidant, essential for the protection of various tissues from the damages of lipid peroxidation. As a trace mineral that is toxic in high doses, selenium is a cofactor for glutathione peroxidase, an anti-oxidant enzyme that neutralizes hydrogen peroxide. L-Selenomethionine is considered a safe, efficacious form of selenium and is readily bioavailable. Selenium may be chemoprotective for certain cancers, particularly prostate cancer. (NCI04) Diagnostic aid in pancreas function determination. Selenomethionine (CAS: 1464-42-2) is an amino acid containing selenium that cannot be synthesized by higher animals but can be obtained from plant material. Selenomethionine is the major seleno-compound in cereal grains (wheat grain, maize, and rice), soybeans, and enriched yeast. Seleno-compounds present in plants may have a profound effect on the health of animals and human subjects. It is now known that the total Se content cannot be used as an indication of its efficacy, but knowledge of individual selenocompounds is necessary to fully assess the significance. Thus, speciation of the seleno-compounds has moved to the forefront. Since animals and man are dependent upon plants for their nutritional requirements, this makes the types of seleno-compounds in plants even more critical. Se enters the food chain through incorporation into plant proteins, mostly as selenocysteine and selenomethionine at normal Se levels. There are two possible pathways for the catabolism of selenomethionine. One is the transsulfuration pathway via selenocystathionine to produce selenocysteine, which in turn is degraded into H2Se by the enzyme beta-lyase. The other pathway is the transamination-decarboxylation pathway. It was estimated that 90\\\\% of methionine is metabolized through this pathway and thus could be also the major route for selenomethionine catabolism (PMID:14748935). Found in onion, cabbage, coco de mono (Lecythis elliptica), Brazil nuts (Bertholletia excelsa), wheat grains and other plants. Dietary supplement for avoidance of Se deficiency in humans and ruminants C26170 - Protective Agent > C275 - Antioxidant The L-enantiomer of selenomethionine. L-SelenoMethionine, an L-isomer of Selenomethionine, is a major natural food-form of selenium. L-SelenoMethionin is a cancer chemopreventive agent that can reduce cancer incidence by dietary supplementation and induce apoptosis of cancer cells. L-SelenoMethionine also can increase expression of glutathione peroxidase[1][2][3]. Selenomethionine is a naturally occurring amino acid containing selenium and is a common natural food source.

Hyoscyamine

BENZENEACETIC ACID, .ALPHA.-(HYDROXYMETHYL)-8-METHYL-8-AZABICYCLO(3.2.1)OCT-3-YL ESTER, ENDO-(+/-)-

Atropine is a racemate composed of equimolar concentrations of (S)- and (R)-atropine. It is obtained from deadly nightshade (Atropa belladonna) and other plants of the family Solanaceae. It has a role as a muscarinic antagonist, an anaesthesia adjuvant, an anti-arrhythmia drug, a mydriatic agent, a parasympatholytic, a bronchodilator agent, a plant metabolite, an antidote to sarin poisoning and a oneirogen. It contains a (S)-atropine and a (R)-atropine. Atropine is an alkaloid originally synthesized from Atropa belladonna. It is a racemic mixture of d-and l-hyoscyamine, of which only l-hyoscyamine is pharmacologically active. Atropine is generally available as a sulfate salt and can be administered by intravenous, subcutaneous, intramuscular, intraosseous, endotracheal and ophthalmic methods. Oral atropine is only available in combination products. Atropine is a competitive, reversible antagonist of muscarinic receptors that blocks the effects of acetylcholine and other choline esters. It has a variety of therapeutic applications, including pupil dilation and the treatment of anticholinergic poisoning and symptomatic bradycardia in the absence of reversible causes. Atropine is a relatively inexpensive drug and is included in the World Health Organization List of Essential Medicines. Atropine is an Anticholinergic and Cholinergic Muscarinic Antagonist. The mechanism of action of atropine is as a Cholinergic Antagonist and Cholinergic Muscarinic Antagonist. Hyoscyamine as a natural plant alkaloid derivative and anticholinergic that is used to treat mild to moderate nausea, motion sickness, hyperactive bladder and allergic rhinitis. Hyoscyamine has not been implicated in causing liver enzyme elevations or clinically apparent acute liver injury. Atropine is a natural product found in Cyphanthera tasmanica, Anthocercis ilicifolia, and other organisms with data available. Atropine Sulfate is the sulfate salt of atropine, a naturally-occurring alkaloid isolated from the plant Atropa belladonna. Atropine functions as a sympathetic, competitive antagonist of muscarinic cholinergic receptors, thereby abolishing the effects of parasympathetic stimulation. This agent may induce tachycardia, inhibit secretions, and relax smooth muscles. (NCI04) Atropine is a synthetically-derived form of the endogenous alkaloid isolated from the plant Atropa belladonna. Atropine functions as a sympathetic, competitive antagonist of muscarinic cholinergic receptors, thereby abolishing the effects of parasympathetic stimulation. This agent may induce tachycardia, inhibit secretions, and relax smooth muscles. (NCI04) Hyoscyamine is a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity. Hyoscyamine functions as a non-selective, competitive antagonist of muscarinic receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal tract. These inhibitory effects cause a decrease in saliva, bronchial mucus, gastric juices, and sweat. Furthermore, its inhibitory action on smooth muscle prevents bladder contraction and decreases gastrointestinal motility.

Putrescine

1,4-Diaminobutane, puriss., >=99.0\\% (GC)

C4H12N2 (88.1)

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). Putrescine is a metabolite found in or produced by Saccharomyces cerevisiae. A toxic diamine formed by putrefaction from the decarboxylation of arginine and ornithine. Putrescine is a polyamine.

Tetrahydrobiopterin

(-)-(6R)-2-Amino-6-((1R,2S)-1,2-dihydroxypropyl)-5,6,7,8-tetrahydro-4(3H)-pteridinone

C9H15N5O3 (241.1175)

Tetrahydrobiopterin (CAS: 17528-72-2), also known as BH4, is an essential cofactor in the synthesis of neurotransmitters and nitric oxide (PMID: 16946131). In fact, it is used by all three human nitric-oxide synthases (NOS) eNOS, nNOS, and iNOS as well as the enzyme glyceryl-ether monooxygenase. It is also essential in the conversion of phenylalanine into tyrosine by the enzyme phenylalanine-4-hydroxylase; the conversion of tyrosine into L-dopa by the enzyme tyrosine hydroxylase; and the conversion of tryptophan into 5-hydroxytryptophan via tryptophan hydroxylase. Specifically, tetrahydrobiopterin is a cofactor for tryptophan 5-hydroxylase 1, tyrosine 3-monooxygenase, and phenylalanine hydroxylase, all of which are essential for the formation of the neurotransmitters dopamine, noradrenaline, and adrenaline. Tetrahydrobiopterin has been proposed to be involved in the promotion of neurotransmitter release in the brain and the regulation of human melanogenesis. A defect in BH4 production and/or a defect in the enzyme dihydropteridine reductase (DHPR) causes phenylketonuria type IV, as well as dopa-responsive dystonias. BH4 is also implicated in Parkinsons disease, Alzheimers disease, and depression. Tetrahydrobiopterin is present in probably every cell or tissue of higher animals. On the other hand, most bacteria, fungi and plants do not synthesize tetrahydrobiopterin (Wikipedia).

5-Aminopentanoic acid

5-Aminovaleric acid hydrochloride

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). It can be found in Corynebacterium (PMID:27717386). 5-aminopentanoic acid is a normal metabolite present in human saliva, with a tendency to elevated concentration in patients with chronic periodontitis.

Argininosuccinic acid disodium

(2S)-2-[[N-[(4S)-4-amino-4-carboxybutyl]carbamimidoyl]amino]butanedioic acid

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.

L-Glutamine

(2S)-2,5-diamino-5-oxopentanoic acid

C5H10N2O3 (146.0691)

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 (‚ÄìNH2) and carboxyl (‚ÄìCOOH) 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‚Äìbrain 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.

L-Arginine

(S)-2-Amino-5-[(aminoiminomethyl)amino]-pentanoic acid

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 (‚ÄìNH2) and carboxyl (‚ÄìCOOH) 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.

The simplest peptide, made of two glycine molecules; used in the synthesis of more complicated peptides. Glycine is a simple, nonessential amino acid, although experimental animals show reduced growth on low-glycine diets. The average adult ingests 3 to 5 grams of glycine daily. Glycine is involved in the bodys production of DNA, phospholipids and collagen, and in release of energy. Glycine levels are effectively measured in plasma in both normal patients and those with inborn errors of glycine metabolism. (http://www.dcnutrition.com/AminoAcids/) Nonketotic hyperglycinaemia (OMIM 606899) is an autosomal recessive condition caused by deficient enzyme activity of the glycine cleavage enzyme system (EC 2.1.1.10).

Guanidinoacetate

2-[[Amino(imino)methyl]amino]acetic acid

C3H7N3O2 (117.0538)

Guanidoacetic acid (GAA), also known as guanidinoacetate or glycocyamine, 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. Guanidinoacetic acid was first prepared in 1861 by Adolph Strecker by reaction of cyanamide with glycine in aqueous solution. Manufactured guanidinoacetic acid is primarily used a feed additive approved by EFSA in poultry farming (for fattening), and pigs for fattening. Guanidoacetic acid exists naturally in all vertebrates. It is formed primarily in the kidneys by transferring the guanidine group of L-arginine to the amino acid glycine via the enzyme known as L-Arg:Gly-amidinotransferase (AGAT). In a further step, guanidinoacetate is methylated to generate creatine using S-adenosyl methionine (as the methyl donor) via the enzyme known as guanidinoacetate N-methyltransferase (GAMT). The resulting creatine is released into the bloodstream. Elevated levels of guanidoacetic acid are a characteristic of an inborn metabolic disorder known as Guanidinoacetate Methyltransferase (GAMT) Deficiency. GAMT converts guanidinoacetate to creatine and deficiency of this enzyme results in creatine depletion and accumulation of guanidinoacetate The disorder is transmitted in an autosomal recessive fashion and is localized to mutations on chromosome 19p13.3. GAMT deficiency is characterized by developmental arrest, medication-resistant epilepsy (myoclonic, generalized tonic-clonic, partial complex, atonic), severe speech impairment, progressive dystonia, dyskinesias, hypotonia, ataxia, and autistic-like behavior. Guanidino acetic acid, also known as guanidinoacetate or glycocyamine, belongs to alpha amino acids and derivatives class of compounds. Those 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. Guanidino acetic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). Guanidino acetic acid can be found in apple and loquat, which makes guanidino acetic acid a potential biomarker for the consumption of these food products. Guanidino acetic acid can be found primarily in most biofluids, including cellular cytoplasm, feces, urine, and cerebrospinal fluid (CSF), as well as in human brain, kidney and liver tissues. In humans, guanidino acetic acid is involved in a couple of metabolic pathways, which include arginine and proline metabolism and glycine and serine metabolism. Guanidino acetic acid is also involved in several metabolic disorders, some of which include dihydropyrimidine dehydrogenase deficiency (DHPD), hyperprolinemia type II, prolinemia type II, and hyperornithinemia-hyperammonemia-homocitrullinuria [hhh-syndrome]. Moreover, guanidino acetic acid is found to be associated with chronic renal failure and schizophrenia. Guanidino acetic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Chronic Exposure: Kidney dialysis is usually needed to relieve the symptoms of uremic syndrome until normal kidney function can be restored.

Guanidinosuccinic acid

(2S)-2-(diaminomethylideneamino)butanedioic acid

C5H9N3O4 (175.0593)

Guanidinosuccinic acid (GSA) has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID:22626821). It is one of the earliest uremic toxins isolated and its toxicity identified. Its metabolic origins show that it arose from the oxidation of argininosuccinic acid (ASA) by free radicals. The stimulus for this oxidation, occurring optimally in the presence of the failed kidney, is the rising level of urea which, through enzyme inhibition, results in a decline in hepatic levels of the semi-essential amino acid, arginine. It is further noted that concentrations of GSA in both serum and urine decline sharply in animals and humans exposed to the essential amino acid, methionine. Uremic patients suffer from a defective ability to generate methyl groups due to anorexia, dietary restrictions and renal protein leakage. This leads to the accumulation of homocysteine, a substance known to produce vascular damage. Even in healthy subjects intake of choline together with methionine is insufficient to satisfy total metabolic requirements for methyl groups. In end-stage renal disease, therefore, protein restriction contributes to the build-up of toxins in uremia. Replacement using specific amino acid mixtures should be directed toward identified deficiencies and adequacy monitored by following serum levels of the related toxins, in this case GSA and homocysteine.

L-Histidine

(2S)-2-amino-3-(1H-imidazol-5-yl)propanoic acid

C6H9N3O2 (155.0695)

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 (‚ÄìNH2) and carboxyl (‚ÄìCOOH) 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-Œ∫B pathway, in adipocytes (PMID: 23361591 ). Low plasma concentrations of histidine are associated with protein-energy...

L-Homoserine

(2S)-2-Amino-4-hydroxybutanoic acid

C4H9NO3 (119.0582)

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

(2S)-2-{[(5S)-5-amino-5-carboxypentyl]amino}pentanedioic acid

C11H20N2O6 (276.1321)

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

The polyamines, found in virtually all living organisms, are a ubiquitous group of compounds that appear to play a vital role in many cellular processes involving nucleic acids including cell growth and differentiation. Acetylation on the terminal nitrogen adjacent to the 4-carbon chain produces N8-acetylspermidine. This reaction is catalyzed by spermidine N8-acetyltransferase and does not result in the conversion of spermidine to putrescine but, instead, the product undergoes deacetylation. This acetyltransferase appears to be associated with chromatin in the cell nucleus and has been reported to be the same as (or related to) the enzyme(s) responsible for histone acetylation. N8-Acetylspermidine does not accumulate in tissues but rather appears to be rapidly deacetylated back to spermidine by a relatively specific cytosolic deacetylase, N8-acetylspermidine deacetylase. The function of this N8-acetylation/deacetylation pathway in cellular processes is not understood clearly, but several observations have suggested a role in cell growth and differentiation.

N-acetylglutamate

N-Acetylglutamate, calcium salt (1:1), (L)-isomer

C7H11NO5 (189.0637)

N-Acetyl-L-glutamic acid or N-Acetylglutamate, 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-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‚Äôs (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.

These are N-acylated alpha-amino acids which have the L-configuration of the alpha-carbon atom. N-Acetylornithine is a minor component of the deproteinized blood plasma of human blood. Human blood plasma contains a variable amount of acetylornithine, averaging 1.1 +/- 0.4 umol/L (range 0.8-0.2 umol/L).

L-Ornithine

(2S)-2,5-diaminopentanoic acid

C5H12N2O2 (132.0899)

Ornithine, also known as (S)-2,5-diaminopentanoic acid or ornithine, (L)-isomer, 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. Ornithine is soluble (in water) and a moderately acidic compound (based on its pKa). Ornithine can be found in a number of food items such as pine nut, lingonberry, turnip, and cassava, which makes ornithine a potential biomarker for the consumption of these food products. Ornithine can be found primarily in most biofluids, including urine, cerebrospinal fluid (CSF), feces, and saliva, as well as throughout most human tissues. Ornithine exists in all living species, ranging from bacteria to humans. In humans, ornithine is involved in few metabolic pathways, which include arginine and proline metabolism, glycine and serine metabolism, spermidine and spermine biosynthesis, and urea cycle. Ornithine is also involved in several metabolic disorders, some of which include ornithine transcarbamylase deficiency (OTC deficiency), prolidase deficiency (PD), citrullinemia type I, and arginine: glycine amidinotransferase deficiency (AGAT deficiency). Moreover, ornithine is found to be associated with cystinuria, alzheimers disease, leukemia, and uremia. Ornithine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Ornithine is a drug which is used for nutritional supplementation, also for treating dietary shortage or imbalance. it has been claimed that ornithine improves athletic performance, has anabolic effects, has wound-healing effects, and is immuno-enhancing. Ornithine is a non-proteinogenic amino acid that plays a role in the urea cycle. Ornithine is abnormally accumulated in the body in ornithine transcarbamylase deficiency. The radical is ornithyl . L-Ornithine is metabolised to L-arginine. L-arginine stimulates the pituitary release of growth hormone. Burns or other injuries affect the state of L-arginine in tissues throughout the body. As De novo synthesis of L-arginine during these conditions is usually not sufficient for normal immune function, nor for normal protein synthesis, L-ornithine may have immunomodulatory and wound-healing activities under these conditions (by virtue of its metabolism to L-arginine) (DrugBank). Chronically high levels of ornithine are associated with at least 9 inborn errors of metabolism including: Cystathionine Beta-Synthase Deficiency, Hyperornithinemia with gyrate atrophy, Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome, Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome, Hyperprolinemia Type II, Lysinuric Protein Intolerance, Ornithine Aminotransferase Deficiency, Ornithine Transcarbamylase Deficiency and Prolinemia Type II (T3DB). Ornithine or L-ornithine, also known as (S)-2,5-diaminopentanoic acid 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-ornithine is soluble (in water) and a moderately basic compound. Ornithine is a non-proteinogenic amino acid that plays a role in the urea cycle. It is considered to be a non-essential amino acid. 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. L-Ornithine is one of the products of the action of the enzyme arginase on L-arginine, creating urea. Therefore, ornithine is a central part of the urea cycle, which allows for the disposal of excess nitrogen. Outside the human body, L-ornithine is abundant in a number of food items such as wild rice, brazil nuts, common oregano, and common grapes. L-ornithine can be found throughout most human tissues; and in most biofluids, some of which include blood, urine, cerebrospinal fluid (CSF), sweat, saliva, and feces. L-ornithine exists in all living species, from bacteria to plants to humans. L-Ornithine is also a precursor of citrulline and arginine. In order for ornithine that is produced in the cytosol to be converted to citrulline, it must first cross the inner mitochondrial membrane into the mitochondrial matrix where it is carbamylated by the enzyme known as ornithine transcarbamylase. This transfer is mediated by the mitochondrial ornithine transporter (SLC25A15; AF112968; ORNT1). Mutations in the mitochondrial ornithine transporter result in hyperammonemia, hyperornithinemia, homocitrullinuria (HHH) syndrome, a disorder of the urea cycle (PMID: 16256388). The pathophysiology of the disease may involve diminished ornithine transport into mitochondria, resulting in ornithine accumulation in the cytoplasm and reduced ability to clear carbamoyl phosphate and ammonia loads (OMIM 838970). In humans, L-ornithine is involved in a number of other metabolic disorders, some of which include, ornithine transcarbamylase deficiency (OTC deficiency), argininemia, and guanidinoacetate methyltransferase deficiency (GAMT deficiency). Ornithine is abnormally accumulated in the body in ornithine transcarbamylase deficiency. Moreover, Ornithine is found to be associated with cystinuria, hyperdibasic aminoaciduria I, and lysinuric protein intolerance, which are inborn errors of metabolism. It has been claimed that ornithine improves athletic performance, has anabolic effects, has wound-healing effects, and is immuno-enhancing. L-Ornithine. CAS Common Chemistry.

Orotic acid

2,6-Dioxo-1,2,3,6-tetrahydro-pyrimidine-4-carboxylic acid

C5H4N2O4 (156.0171)

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].

C21H26O5 (358.178)

Prednisone is only found in individuals that have used or taken this drug. It is a synthetic anti-inflammatory glucocorticoid derived from cortisone. It is biologically inert and converted to prednisolone in the liver. [PubChem]Prednisone is a glucocorticoid receptor agonist. It is first metabolized in the liver to its active form, prednisolone. Prednisolone crosses cell membranes and binds with high affinity to specific cytoplasmic receptors. The result includes inhibition of leukocyte infiltration at the site of inflammation, interference in the function of mediators of inflammatory response, suppression of humoral immune responses, and reduction in edema or scar tissue. The antiinflammatory actions of corticosteroids are thought to involve phospholipase A2 inhibitory proteins, lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes.

Pyrrole-2-carboxylic acid

1H-Pyrrole-2-carboxylic acid

C5H5NO2 (111.032)

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. (PMID:4430715). Urinary excretion of N-(pyrrole-2-carboxyl) glycine has been reported in a 5-year-old affected with type II hyperprolinemia; The child has mild developmental delay, recurrent seizures of the grand mal type and EEG alterations.

C17H21NO4 (303.1471)

Scopolamine, also known as hyoscine, is a tropane alkaloid drug obtained from plants of the family Solanaceae (nightshades), such as henbane or jimson weed (Datura species). It is part of the secondary metabolites of plants. Scopolamine is used criminally as a date rape drug and as an aid to robbery, the most common act being the clandestine drugging of a victims drink. It is preferred because it induces retrograde amnesia, or an inability to recall events prior to its administration. Victims of this crime are often admitted to a hospital in police custody, under the assumption that the patient is experiencing a psychotic episode. A telltale sign is a fever accompanied by a lack of sweat. An alkaloid from Solanaceae, especially Datura metel L. and Scopola carniolica. Scopolamine and its quaternary derivatives act as antimuscarinics like atropine, but may have more central nervous system effects. Among the many uses are as an anesthetic premedication, in urinary incontinence, in motion sickness, as an antispasmodic, and as a mydriatic and cycloplegic.

Sepiapterin

2-Amino-7,8-dihydro-6-((2S)-2-hydroxy-1-oxopropyl)-4(3H)-pteridinone acid

Sepiapterin, also known as 2-amino-6-lactoyl-7,8-dihydropteridin-4(3H)-one, belongs to the class of organic compounds known as pterins and derivatives. These are polycyclic aromatic compounds containing a pterin moiety, which consist of a pteridine ring bearing a ketone and an amine group to form 2-aminopteridin-4(3H)-one. Sepiapterin is also classified as a member of the pteridine class of organic chemicals. It is a yellow fluorescing pigment. Sepiapterin is an intermediate in the salvage pathway of tetrahydrobiopterin (BH(4)). More specifically, sepiapterin can be metabolized into tetrahydrobiopterin via the BH(4) salvage pathway. Tetrahydrobiopterin is an essential cofactor in humans for breakdown of phenylalanine and a catalyst of the metabolism of phenylalanine, tyrosine, and tryptophan to the neurotransmitters dopamine and serotonin. A deficiency of tetrahydrobiopterin can cause toxic buildup of phenylalanine (phenylketonuria) as well as deficiencies of dopamine, norepinephrine, and epinephrine, leading to dystonia and other neurological illnesses. Sepiapterin accumulates in the brain of patients with sepiapterin reductase (SR) deficiency, an inborn error of metabolism. Sepiapterin reductase deficiency is a condition characterized by movement problems, most often a pattern of involuntary, sustained muscle contractions known as dystonia. Other movement problems can include muscle stiffness (spasticity), tremors, problems with coordination and balance (ataxia), and involuntary jerking movements (chorea). People with sepiapterin reductase deficiency can experience episodes called oculogyric crises. These episodes involve abnormal rotation of the eyeballs; extreme irritability and agitation; and pain, muscle spasms, and uncontrolled movements, especially of the head and neck. Movement abnormalities are often worse late in the day. Most affected individuals have delayed development of motor skills such as sitting and crawling, and they typically are not able to walk unassisted. The problems with movement tend to worsen over time. Within humans, sepiapterin participates in a number of enzymatic reactions. In particular, sepiapterin can be converted into 7,8-dihydroneopterin; which is mediated by the enzyme sepiapterin reductase. In addition, sepiapterin can be converted into 7,8-dihydroneopterin through its interaction with the enzyme carbonyl reductase [NADPH] 1. Sepiapterin is an intermediate in the salvage pathway of tetrahydrobiopterin (BH(4)). It is a yellow fluorescing pigment. Sepiapterin accumulates in the brain of patients with sepiapterin reductase (SR) deficiency. [HMDB] C307 - Biological Agent

Spermine

(3-aminopropyl)({4-[(3-aminopropyl)amino]butyl})amine

C10H26N4 (202.2157)

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.

Dihydrobiopterin

2-amino-6-[(1R,2S)-1,2-dihydroxypropyl]-1,4,7,8-tetrahydropteridin-4-one

C9H13N5O3 (239.1018)

Dihydrobiopterin, also known as BH2, 7,8-dihydrobiopterin, L-erythro-7,8-dihydrobiopterin, quinonoid dihydrobiopterin or q-BH2, belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative. Dihydrobiopterin is also classified as a pteridine. Pteridines are aromatic compounds composed of fused pyrimidine and pyrazine rings. Dihydrobiopterin is produced during the synthesis of neurotransmitters L-DOPA, dopamine, norepinephrine and epinephrine. It is restored to the required cofactor tetrahydrobiopterin via the NADPH-dependant reduction of dihydrobiopterin reductase. Dihydrobiopterin can also be converted to tetrahydrobiopterin by nitric oxide synthase (NOS) which is catalyzed by the flavoprotein "diaphorase" activity of NOS. This activity is located on the reductase (C-terminal) domain of NOS, whereas the high affinity tetrahydrobiopterin site involved in NOS activation is located on the oxygenase (N-terminal) domain (PMID: 8626754). Sepiapterin reductase (SPR) is another enzyme that plays a role in the production of dihydrobiopterin. SPR catalyzes the reduction of sepiapterin to dihydrobiopterin (BH2), the precursor for tetrahydrobiopterin (BH4). BH4 is a cofactor critical for nitric oxide biosynthesis and alkylglycerol and aromatic amino acid metabolism (PMID: 25550200). Dihydrobiopterin is known to be synthesized in several parts of the body, including the pineal gland. Dihydrobiopterin exists in all eukaryotes, ranging from yeast to humans. In humans, dihydrobiopterin is involved in several metabolic disorders including dihydropteridine reductase (DHPR) deficiency. DHPR deficiency is a severe form of hyperphenylalaninemia (HPA) due to impaired regeneration of tetrahydrobiopterin (BH4) leading to decreased levels of neurotransmitters (dopamine, serotonin) and folate in cerebrospinal fluid, and causing neurological symptoms such as psychomotor delay, hypotonia, seizures, abnormal movements, hypersalivation, and swallowing difficulties. Dihydrobiopterin is also associated with another metabolic disorder known as sepiapterin reductase deficiency (SRD). Sepiapterin reductase catalyzes the (NADP-dependent) reduction of carbonyl derivatives, including pteridines, and plays an important role in tetrahydrobiopterin biosynthesis. Low dihydrofolate reductase activity in the brain leads to the accumulation of dihydrobiopterin, which in turn, inhibits tyrosine and tryptophan hydroxylases. This uncouples neuronal nitric oxide synthase, leading to neurotransmitter deficiencies and neuronal cell death. SRD is characterized by low cerebrospinal fluid neurotransmitter levels and the presence of elevated cerebrospinal fluid dihydrobiopterin. SRD is characterized by motor delay, axial hypotonia, language delay, diurnal fluctuation of symptoms, dystonia, weakness, oculogyric crises, dysarthria, parkinsonian signs and hyperreflexia. Dihydrobiopterin (BH2) is an oxidation product of tetrahydrobiopterin. Tetrahydrobiopterin is a natural occurring cofactor of the aromatic amino acid hydroxylase and is involved in the synthesis of tyrosine and the neurotransmitters dopamine and serotonin. Tetrahydrobiopterin is also essential for nitric oxide synthase catalyzed oxidation of L-arginine to L-citrulline and nitric oxide. [HMDB] 7,8-Dihydro-L-biopterin is an oxidation product of tetrahydrobiopterin.

Sildenafil

C22H30N6O4S (474.2049)

Sildenafil is a drug used to treat male erectile dysfunction (impotence) and pulmonary arterial hypertension (PAH), developed by the pharmaceutical company Pfizer. It was initially studied for use in hypertension (high blood pressure) and angina pectoris (a form of ischaemic cardiovascular disease). Phase I clinical trials under the direction of Ian Osterloh suggested that the drug had little effect on angina, but that it could induce marked penile erections; Sildenafil is a potent and selective inhibitor of cGMP specific phosphodiesterase type 5 (PDE5) which is responsible for degradation of cGMP in the corpus cavernosum. The molecular structure of sildenafil is similar to that of cGMP and acts as a competitive binding agent of PDE5 in the corpus cavernosum, resulting in more cGMP and better erections. Without sexual stimulation, and therefore lack of activation of the NO/cGMP system, sildenafil should not cause an erection. Other drugs that operate by the same mechanism include tadalafil (Cialis) and vardenafil (Levitra); Sildenafil citrate, sold under the names Viagra, Revatio and generically under various other names, is a drug used to treat male erectile dysfunction (impotence) and pulmonary arterial hypertension (PAH), developed by the pharmaceutical company Pfizer. Viagra pills are blue and diamond-shaped with the words Pfizer on one side, and VGR xx (where xx stands for 25, 50 or 100, the dose of that pill in milligrams) on the other. Its primary competitors on the market are tadalafil (Cialis), and vardenafil (Levitra).

L-Norleucine

(S)-2-amino-Hexanoic acid

C6H13NO2 (131.0946)

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. An unnatural amino acid that is used experimentally to study protein structure and function. It is structurally similar to methionine, however it does not contain sulfur. Acquisition and generation of the data is financially supported in part by CREST/JST.

C13H24N4O3S (316.1569)

Timolol is only found in individuals that have used or taken this drug. It is a beta-adrenergic antagonist similar in action to propranolol. The levo-isomer is the more active. Timolol has been proposed as an antihypertensive, antiarrhythmic, antiangina, and antiglaucoma agent. It is also used in the treatment of migraine disorders and tremor. [PubChem]Like propranolol and nadolol, timolol competes with adrenergic neurotransmitters such as catecholamines for binding at beta(1)-adrenergic receptors in the heart and vascular smooth muscle and beta(2)-receptors in the bronchial and vascular smooth muscle. Beta(1)-receptor blockade results in a decrease in resting and exercise heart rate and cardiac output, a decrease in both systolic and diastolic blood pressure, and, possibly, a reduction in reflex orthostatic hypotension. Beta(2)-blockade results in an increase in peripheral vascular resistance. The exact mechanism whereby timolol reduces ocular pressure is still not known. The most likely action is by decreasing the secretion of aqueous humor.

Paroxetine

(-)-(3S,4R)-4-(p-Fluorophenyl)-3-((3,4-(methylenedioxy)phenoxy)methyl)piperidine

C19H20FNO3 (329.1427)

Paroxetine hydrochloride and paroxetine mesylate belong to a class of antidepressant agents known as selective serotonin-reuptake inhibitors (SSRIs). Despite distinct structural differences between compounds in this class, SSRIs possess similar pharmacological activity. As with other antidepressant agents, several weeks of therapy may be required before a clinical effect is seen. SSRIs are potent inhibitors of neuronal serotonin reuptake. They have little to no effect on norepinephrine or dopamine reuptake and do not antagonize α- or β-adrenergic, dopamine D₂ or histamine H₁ receptors. During acute use, SSRIs block serotonin reuptake and increase serotonin stimulation of somatodendritic 5-HT_1A and terminal autoreceptors. Chronic use leads to desensitization of somatodendritic 5-HT_1A and terminal autoreceptors. The overall clinical effect of increased mood and decreased anxiety is thought to be due to adaptive changes in neuronal function that leads to enhanced serotonergic neurotransmission. Side effects include dry mouth, nausea, dizziness, drowsiness, sexual dysfunction and headache (see Toxicity section below for a complete listing of side effects). Side effects generally occur during the first two weeks of therapy and are usually less severe and frequent than those observed with tricyclic antidepressants. Paroxetine hydrochloride and mesylate are considered therapeutic alternatives rather than generic equivalents by the US Food and Drug Administration (FDA); both agents contain the same active moiety (i.e. paroxetine), but are formulated as different salt forms. Clinical studies establishing the efficacy of paroxetine in various conditions were performed using paroxetine hydrochloride. Since both agents contain the same active moiety, the clinical efficacy of both agents is thought to be similar. Paroxetine may be used to treat major depressive disorder (MDD), panic disorder with or without agoraphobia, obsessive-compulsive disorder (OCD), social anxiety disorder (social phobia), generalized anxiety disorder (GAD), post-traumatic stress disorder (PTSD) and premenstrual dysphoric disorder (PMDD). Paroxetine has the most evidence supporting its use for anxiety-related disorders of the SSRIs. It has the greatest anticholinergic activity of the agents in this class and compared to other SSRIs, paroxetine may cause greater weight gain, sexual dysfunction, sedation and constipation.

C10H12O2 (164.0837)

Benzenebutanoic acid (also known as 4-phenylbutyrate, or 4-PBA) is the oral form of butyrate, which is known to be a transcriptional regulator. Sodium-4-PBA has been shown to induce fetal hemoglobin, and it has been used in clinical trials for sickle cell anemia and β-thalassemia. Because gene expression profiles became more differentiated, it is in phase I trials in several different malignant disorders. The potential for therapeutic benefit in cystic fibrosis (CF) resides in an additional mechanism, involving protein folding and the ER (endoplasmic reticulum) environment (PMID 12458151). 4-PBA is a drug that was developed to treat elevated blood ammonia in urea cycle disorders, a histone deacetylase inhibitor that promotes mutation ΔF508 cystic fibrosis transmembrane conductance regulator (CFTR) trafficking (PMID 16798551). 4-phenylbutyrate (4-PBA) is known to be a transcriptional regulator, and sodium-4-PBA has been shown to induce fetal hemoglobin, and it has been used in clinical trials for sickle cell anemia and β-thalassemia Because gene expression profiles became more differentiated, it is in phase I trials in several different malignant disorders.

C19H24N2O2 (312.1838)

Praziquantel is only found in individuals that have used or taken this drug. It is an anthelmintic used in most schistosome and many cestode infestations. [PubChem]Praziquantel works by causing severe spasms and paralysis of the worms muscles. This paralysis is accompanied - and probably caused - by a rapid Ca 2+ influx inside the schistosome. Morphological alterations are another early effect of praziquantel. These morphological alterations are accompanied by an increased exposure of schistosome antigens at the parasite surface. The worms are then either completely destroyed in the intestine or passed in the stool. An interesting quirk of praziquantel is that it is relatively ineffective against juvenile schistosomes. While initially effective, effectiveness against schistosomes decreases until it reaches a minimum at 3-4 weeks. Effectiveness then increases again until it is once again fully effective at 6-7 weeks. Glutathione S-transferase (GST), an essential detoxification enzyme in parasitic helminths, is a major vaccine target and a drug target against schistosomiasis. Schistosome calcium ion channels are currently the only known target of praziquantel.

Acetovanillone

1-(4-hydroxy-3-methoxyphenyl)ethan-1-one

C9H10O3 (166.063)

Acetovanillone, also known as 4-hydroxy-3-methoxyacetophenone or acetoguaiacon, is a member of the class of compounds known as alkyl-phenylketones. Alkyl-phenylketones are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. Acetovanillone is slightly soluble (in water) and a very weakly acidic compound (based on its pKa).

Spermidine

N-(gamma-Aminopropyl)tetramethylenediamine

C7H19N3 (145.1579)

Spermidine, also known as SPD, 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. Abnormal bleeding, such as bleeding spontaneously or profusely from a very minor injury can also occur. Spermidine exists in all living species, ranging from bacteria to humans. Within humans, spermidine participates in a number of enzymatic reactions. In particular, 5-methylthioadenosine and spermidine can be biosynthesized from S-adenosylmethioninamine and putrescine by the enzyme spermidine synthase. In addition, S-adenosylmethioninamine and spermidine can be converted into 5-methylthioadenosine and spermine through the action of the enzyme spermine synthase. In humans, spermidine is involved in spermidine and spermine biosynthesis. Outside of the human body, spermidine is found, on average, in the highest concentration within cow milk and oats. Spermidine has also been detected, but not quantified in several different foods, such as common chokecherries, watercress, agars, strawberry guava, and bog bilberries. This could make spermidine a potential biomarker for the consumption of these foods. Spermidine is consideres as an uremic toxine. Increased levels of uremic toxins can stimulate the production of reactive oxygen species. Chronic exposure to uremic toxins can lead to a number of conditions including renal damage, chronic kidney disease and cardiovascular disease. As a uremic toxin, this compound can cause uremic syndrome. Uremic toxins such as spermidine are actively transported into the kidneys via organic ion transporters (especially OAT3).

C38H72N2O12 (748.5085)

Azithromycin is a macrolide antibiotic useful for the treatment of bacterial infections. It has a role as an antibacterial drug, an environmental contaminant and a xenobiotic. ["Azithromycin is an antibacterial prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of certain bacterial infections, such as:","Various bacterial respiratory diseases, including community-acquired pneumonia, acute sinus and ear infections, acute worsening of chronic bronchitis, and throat and tonsil infections","Pelvic inflammatory disease","Genital ulcer disease and infections of the urethra and cervix","Infections of the skin","Community-acquired pneumonia, a bacterial respiratory disease, can be an opportunistic infection (OI) of HIV."] Azithromycin is a broad-spectrum macrolide antibiotic with a long half-life and a high degree of tissue penetration. It was initially approved by the FDA in 1991. It is primarily used for the treatment of respiratory, enteric and genitourinary infections and may be used instead of other macrolides for some sexually transmitted and enteric infections. It is structurally related to erythromycin. Azithromycin [9-deoxo-9a-aza-9a-methyl-9a-homoerythromycin] is a part of the azalide subclass of macrolides, and contains a 15-membered ring, with a methyl-substituted nitrogen instead of a carbonyl group at the 9a position on the aglycone ring, which allows for the prevention of its metabolism. This differentiates azithromycin from other types of macrolides. In March 2020, a small study was funded by the French government to investigate the treatment of COVID-19 with a combination of azithromycin and the anti-malaria drug [hydroxychloroquine]. The results were positive, all patients taking the combination were virologically cured within 6 days of treatment, however, larger studies are required. Azithromycin anhydrous is a Macrolide Antimicrobial. Azithromycin is a semisynthetic macrolide antibiotic which is commonly used for a wide variety of mild-to-moderate bacterial infections. Azithromycin has been linked to rare instances of acute liver injury. Azithromycin Anhydrous is the anhydrous form of azithromycin, an orally bioavailable azalide derived from erythromycin, and a member of a subclass of macrolide antibiotics, with anti-bacterial activity. Upon oral administration, azithromycin reversibly binds to the 23S rRNA of the 50S ribosomal subunit of the bacterial ribosome of susceptible microorganisms, thereby inhibiting the translocation step of protein synthesis by preventing the assembly of the 50S ribosomal subunit. This inhibits bacterial protein synthesis, inhibits cell growth and causes cell death. Azithromycin is an azalide, derived from erythromycin, and a member of a subclass of macrolide antibiotics with bacteriocidal and bacteriostatic activities. Azithromycin reversibly binds to the 50S ribosomal subunit of the 70S ribosome of sensitive microorganisms, thereby inhibiting the translocation step of protein synthesis, wherein a newly synthesized peptidyl tRNA molecule moves from the acceptor site on the ribosome to the peptidyl (donor) site, and consequently inhibiting RNA-dependent protein synthesis leading to cell growth inhibition and cell death. A semi-synthetic macrolide antibiotic structurally related to ERYTHROMYCIN. It has been used in the treatment of Mycobacterium avium intracellulare infections, toxoplasmosis, and cryptosporidiosis. Azithromycin is a semi-synthetic macrolide antibiotic of the azalide class. It is used to treat certain bacterial infections, most often bacteria causing middle ear infections, tonsillitis, throat infections, laryngitis, bronchitis, pneumonia, and sinusitis. It is also effective against certain sexually transmitted infectious diseases, such as non-gonococcal urethritis and cervicitis. Like other macrolide antibiotics, azithromycin inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit of the bacterial 70S ribosome. Binding inhibits peptidyl transferase activity and interferes with amino acid translocation during the process of translation. Its effects may be bacteriostatic or bactericidal depending of the organism and the drug concentration. Its long half-life, which enables once-daily dosing, and shorter administration durations is a property distinct from other macrolides. Azithromycin is derived from erythromycin; however, it differs chemically from erythromycin in that a methyl-substituted nitrogen atom is incorporated into the lactone ring, thus making the lactone ring 15-membered. Azithromycin is sold under the brand names Zithromax ("Zmax") and Sumamed, and is one of the worlds best-selling antibiotics.

Urea

Carbonyl diamide

Urea is a highly soluble organic compound formed in the liver from ammonia produced by the deamination of amino acids. It is the principal end product of protein catabolism and constitutes about one half of the total urinary solids. Urea is formed in a cyclic pathway known simply as the urea cycle. In this cycle, amino groups donated by ammonia and L-aspartate are converted to urea. Urea is essentially a waste product; it has no physiological function. It is dissolved in blood (in humans in a concentration of 2.5 - 7.5 mmol/liter) and excreted by the kidney in the urine. In addition, a small amount of urea is excreted (along with sodium chloride and water) in human sweat. Urea is found to be associated with primary hypomagnesemia, which is an inborn error of metabolism.

C6H13N3O3 (175.0957)

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).

Acetylcholine

Bournonville brand OF acetylcholine chloride

[C7H16NO2]+ (146.1181)

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).

Asymmetric dimethylarginine

(2S)-2-amino-5-[(E)-[amino(dimethylamino)methylidene]amino]pentanoic acid

C8H18N4O2 (202.143)

Asymmetric dimethylarginine (ADMA) is a naturally occurring chemical found in blood plasma. It is a metabolic by-product of continual protein modification processes in the cytoplasm of all human cells. It is closely related to L-arginine, a conditionally-essential amino acid. ADMA interferes with L-arginine in the production of nitric oxide, a key chemical to endothelial and hence cardiovascular health. Asymmetric dimethylarginine is created in protein methylation, a common mechanism of post-translational protein modification. This reaction is catalyzed by an enzyme set called S-adenosylmethionine protein N-methyltransferases (protein methylases I and II). The methyl groups transferred to create ADMA are derived from the methyl group donor S-adenosylmethionine, an intermediate in the metabolism of homocysteine. (Homocysteine is an important blood chemical, because it is also a marker of cardiovascular disease). After synthesis, ADMA migrates into the extracellular space and thence into blood plasma. Asymmetric dimethylarginine is measured using high performance liquid chromatography. ADMA has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Isolated from broad bean seeds (Vicia faba). NG,NG-Dimethyl-L-arginine is found in many foods, some of which are yellow wax bean, spinach, green zucchini, and white cabbage.

Homo-L-arginine

(2S)-2-amino-6-carbamimidamidohexanoic acid

L-homoarginine, also known as N6-(aminoiminomethyl)-L-lysine or N6-amidino-L-lysine, 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. More specifically, L-homoarginine is a naturally occurring, non-proteinogenic, cationic amino acid. It is formed in the liver in a reaction catalyzed by L-arginine:glycine amidinotransferase (AGAT) when transferring the amidino group from arginine to lysine. It is an alternative substrate for nitric oxide (NO) synthase. L-homoarginine increases the availability of NO and thereby affects endothelial function. High homoarginine levels may exert positive actions that are relevant to cardiovascular health, including enhanced endothelial function, inhibition of platelet aggregation and stimulation of insulin secretion (PMID: 30866658). Recent studies have demonstrated that low serum homoarginine levels are a strong predictor of cardiovascular mortality (PMID: 24583919). L-homoarginine is a substrate of the human cationic amino acid CAT1 [solute carrier family 7 (SLC7A1)], CAT2A (SLC7A2A) or CAT2B (SLC7A2B) (PMID: 28684763). According to published human metabolomic data, L-homoarginine can be found primarily in blood, cerebrospinal fluid (CSF), and urine, as well as in human intestinal and testes tissues. Moreover, L-homoarginine has been found to be associated with liver cirrhosis and the genetic disorder, hyperargininemia. Homoarginine is an organ-specific uncompetitive inhibitor of human liver and bone alkaline phosphohydrolase (PMID: 5063678). H-HoArg-OH, a homologue arginine, is a strong inhibitor of human bone and liver alkaline phosphatase.

Lipoxin A4

(7E,9E,11Z,13E)-(5S,6R,15S)-5,6,15-Trihydroxyicosa-7,9,11,13-tetraenoic acid

Lipoxin A4 (LXA4) was first identified in 1984 by Serhan and colleagues as 5-lipoxygenase interaction product of activated leukocytes. Endogenous transcellular biosynthesis of LXA4 occurs via interaction of leukocytes with epithelium, endothelium or platelets. Lipoxins (LXs) or the lipoxygenase interaction products are generated from arachidonic acid via sequential actions of lipoxygenases and subsequent reactions to give specific trihydroxytetraene-containing eicosanoids. These unique structures are formed during cell-cell interactions and appear to act at both temporal and spatially distinct sites from other eicosanoids produced during the course of inflammatory responses and to stimulate natural resolution. Lipoxin A4 (LXA4) and lipoxin B4 (LXB4) are positional isomers that each possesses potent cellular and in vivo actions. These LX structures are conserved across species. The results of numerous studies reviewed in this work now confirm that they are the first recognized eicosanoid chemical mediators that display both potent anti-inflammatory and pro-resolving actions in vivo in disease models that include rabbit, rat, and mouse systems. LXs act at specific GPCRs as agonists to regulate cellular responses of interest in inflammation and resolution. Aspirin has a direct impact in the LX circuit by triggering the biosynthesis of endogenous epimers of LX, termed the aspirin-triggered 15-epi-LX, that share the potent anti-inflammatory actions of LX.

C2H7N (45.0578)

Dimethylamine (DMA) is an organic secondary amine. It is a colorless, liquefied and flammable gas with an ammonia and fish-like odor. Dimethylamine is abundantly present in human urine. Main sources of urinary DMA have been reported to include trimethylamine N-oxide, a common food component, and asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide (NO) synthesis. ADMA is excreted in the urine in part unmetabolized and in part after hydrolysis to DMA by dimethylarginine dimethylaminohydrolase (DDAH). Statistically significant increases in urinary DMA have been found in individuals after the consumption of fish and seafoods. The highest values were obtained for individuals that consumed coley, squid and whiting with cod, haddock, sardine, skate and swordfish (PMID: 18282650). It has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). As a pure chemical substance Dimethylamine is used as dehairing agent in tanning, in dyes, in rubber accelerators, in soaps and cleaning compounds and as an agricultural fungicide. In the body, DMA also undergoes nitrosation under weak acid conditions to give dimethlynitrosamine.

Dihydronicotinamide-adenine dinucleotide

C21H29N7O14P2 (665.1248)

Nicotinamide adenine dinucleotide (NAD) is a coenzyme central to metabolism. Found in all living cells, NAD is called a dinucleotide because it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine nucleobase and the other nicotinamide. NAD exists in two forms: an oxidized and reduced form, abbreviated as NAD+ and NADH (H for hydrogen) respectively. NADH is the reduced form of NAD+, and NAD+ is the oxidized form of NADH. NAD (or nicotinamide adenine dinucleotide) is used extensively in glycolysis and the citric acid cycle of cellular respiration. The reducing potential stored in NADH can be either converted into ATP through the electron transport chain or used for anabolic metabolism. ATP "energy" is necessary for an organism to live. Green plants obtain ATP through photosynthesis, while other organisms obtain it via cellular respiration. NAD is a coenzyme composed of ribosylnicotinamide 5-diphosphate coupled to adenosine 5-phosphate by a pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH). NADP is formed through the addition of a phosphate group to the 2 position of the adenosyl nucleotide through an ester linkage.

Nevadensin, also known as pedunculin or 5,7-hydroxy-4,6,8-trimethoxyflavone, is a member of the class of compounds known as 8-o-methylated flavonoids. 8-o-methylated flavonoids are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. Thus, nevadensin is considered to be a flavonoid lipid molecule. Nevadensin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Nevadensin can be found in peppermint and sweet basil, which makes nevadensin a potential biomarker for the consumption of these food products. Nevadensin is a naturally occurring selective inhibitor of human carboxylesterase 1 (hCE1) with an IC50 of 2.64 μM.

Resolvin D1 (RvD1) is an autacoid resolvin. Autacoids are chemical mediators including the families of resolvins and protectins, defined by their potent bioactions and novel chemical structures. The bioactive local mediators, or autacoids, that require enzymatic generation from the omega-3 essential fatty acid EPA were first identified in resolving inflammatory exudates in vivo and carry potent stereoselective biological actions. Resolvins of the E (RvE) series are derived from eicosapentaenoic acid (EPA). Those derived from docosahexaenoic acid (DHA) were termed resolvins of the D series, for example resolvin D1 (RvD1).Resolvins and protectins have specific stereoselective actions which evoke biological actions in the nanogram range in vivo and are natural exudate products. Resolvins and protectins as distinct chemical families join the lipoxins as potent agonists of endogenous anti-inflammation and are proresolving chemical mediators of interest in human disease as potential new approaches to treatment. The term resolvins (resolution-phase interaction products) was first introduced to signify that these new structures were endogenous mediators, biosynthesized in the resolution phase of inflammatory exudates, possessing very potent anti-inflammatory and immunoregulatory actions. These actions include reducing neutrophil traffic, regulating cytokine and reactive oxygen species, and lowering the magnitude of the response. In recent years, investigators have recognized inflammation as playing a key role in many prevalent diseases not previously considered to be of inflammatory etiology. These include Alzheimers disease, cardiovascular disease, and cancer, which now join those well-appreciated inflammatory disorders such as arthritis and periodontal disease. Identifying the molecular mechanism(s) that underlie the many reports of the benefits of dietary omega-3 PUFAs remains an important challenge for nutrition and medicine. Thus, that these new mediator families, resolvins and protectins, are biosynthesized from EPA and DHA, act locally, and possess potent, novel bioactions is of interest to researchers.

1-Pyrroline-5-carboxylic acid (CAS: 2906-39-0) is an enamine or an imino acid that forms upon the spontaneous dehydration of L-glutamate gamma-semialdehyde in aqueous solutions. The stereoisomer (S)-1-pyrroline-5-carboxylate is an intermediate in glutamate metabolism, arginine degradation, and proline biosynthesis and degradation. It can also be converted into or be formed from three amino acids: L-glutamate, L-ornithine, and L-proline. In particular, it is synthesized via the oxidation of proline by pyrroline-5-carboxylate reductase 1 (PYCR1) (EC 1.5.1.2) or by proline dehydrogenase (PRODH) (EC 1.5.99.8). It is hydrolyzed into L-glutamate by delta-1-pyrroline-5-carboxylate dehydrogenase (ALDH4A1) (EC 1.5.1.12). It is also one of the few metabolites that can act as a precursor to other metabolites of both the urea cycle and the tricarboxylic acid (TCA) cycle. Under certain conditions, pyrroline-5-carboxylate 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 pyrroline-5-carboxylate 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. Hyperprolinemia type II results in high levels of pyrroline-5-carboxylate. People with hyperprolinemia type II have signs and symptoms that vary in severity, but they are more likely than type I to have seizures or intellectual disability. Pyrroline-5-carboxylate is highly reactive and excess quantities have been shown to cause cell death and apoptosis (PMID: 15548746). (s)-1-pyrroline-5-carboxylate, also known as delta-1-pyrroline-5-carboxylate, (+-)-isomer, belongs to alpha amino acids and derivatives class of compounds. Those 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 (s)-1-pyrroline-5-carboxylate is soluble (in water) and a moderately acidic compound (based on its pKa). (s)-1-pyrroline-5-carboxylate can be found in a number of food items such as beech nut, mango, oyster mushroom, and other bread, which makes (s)-1-pyrroline-5-carboxylate a potential biomarker for the consumption of these food products (s)-1-pyrroline-5-carboxylate may be a unique E.coli metabolite.

1-Methylguanidine

1-Methylguanidine hydrochloride

C2H7N3 (73.064)

Methylguanidine (MG) is a guanidine in which one of the amino hydrogens of guanidine itself is substituted by a methyl group. Methylguanidine is a guanidine compound deriving from protein catabolism. It is also a product of putrefaction. Methylguanidine has a role as a metabolite, an EC 1.14.13.39 (nitric oxide synthase) inhibitor and as a uremic toxin. It has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID:22626821). It accumulates in renal failure, however it also exhibits anti-inflammatory effects. Methylguanidine is synthesized from creatinine concomitant with the synthesis of hydrogen peroxide from endogenous substrates in peroxisomes. Recent evidence suggests that methylguanidine significantly inhibits iNOS activity and TNF- release. This means that methylguandine can attenuate the degree of inflammation and tissue damage associated with endotoxic shock.

Prostaglandin B2

(5Z)-7-{2-[(1E,3R)-3-hydroxyoct-1-en-1-yl]-5-oxocyclopent-1-en-1-yl}hept-5-enoic acid

C20H30O4 (334.2144)

Prostaglandin B2 (PGB2) is a prostanoid. Prostanoids is a term that collectively describes prostaglandins, prostacyclines and thromboxanes. Prostanoids are a subclass of the lipid mediator group known as eicosanoids. They derive from C-20 polyunsaturated fatty acids, mainly dihomo-gamma-linoleic (20:3n-6), arachidonic (20:4n-6), and eicosapentaenoic (20:5n-3) acids, through the action of cyclooxygenases-1 and -2 (COX-1 and COX-2). The reaction product of COX is the unstable endoperoxide prostaglandin H (PGH) that is further transformed into the individual prostanoids by a series of specific prostanoid synthases. Prostanoids are local-acting mediators formed and inactivated within the same or neighbouring cells prior to their release into circulation as inactive metabolites (15-keto- and 13,14-dihydroketo metabolites). Non-enzymatic peroxidation of arachidonic acid and other fatty acids in vivo can result in prostaglandin-like substances isomeric to the COX-derived prostaglandins that are termed isoprostanes. Prostanoids take part in many physiological and pathophysiological processes in practically every organ, tissue and cell, including the vascular, renal, gastrointestinal and reproductive systems. Their activities are mediated through prostanoid-specific receptors and intracellular signalling pathways, whilst their biosynthesis and action are blocked by nonsteroidal antiinflammatory drugs (NSAID). Isoprostanes are considered to be reliable markers of oxidant stress status and have been linked to inflammation, ischaemia-reperfusion, diabetes, cardiovascular disease, reproductive disorders and diabetes. (PMID: 16986207). Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. Prostaglandin B2 (PGB2) is a prostanoid.

Resolvin D2 is an autacoid resolvin. Autacoids are chemical mediators including the families of resolvins and protectins, defined by their potent bioactions and novel chemical structures. The bioactive local mediators, or autacoids, that require enzymatic generation from the omega-3 essential fatty acid EPA were first identified in resolving inflammatory exudates in vivo and carry potent stereoselective biological actions. Resolvins of the E (RvE) series are derived from eicosapentaenoic acid (EPA). Those derived from docosahexaenoic acid (DHA) were termed resolvins of the D series, for example resolvin D1 (RvD1).Resolvins and protectins have specific stereoselective actions which evoke biological actions in the nanogram range in vivo and are natural exudate products. Resolvins and protectins as distinct chemical families join the lipoxins as potent agonists of endogenous anti-inflammation and are proresolving chemical mediators of interest in human disease as potential new approaches to treatment. The term resolvins (resolution-phase interaction products) was first introduced to signify that these new structures were endogenous mediators, biosynthesized in the resolution phase of inflammatory exudates, possessing very potent anti-inflammatory and immunoregulatory actions. These actions include reducing neutrophil traffic, regulating cytokine and reactive oxygen species, and lowering the magnitude of the response. In recent years, investigators have recognized inflammation as playing a key role in many prevalent diseases not previously considered to be of inflammatory etiology. These include Alzheimers disease, cardiovascular disease, and cancer, which now join those well-appreciated inflammatory disorders such as arthritis and periodontal disease. Identifying the molecular mechanism(s) that underlie the many reports of the benefits of dietary omega-3 PUFAs remains an important challenge for nutrition and medicine. Thus, that these new mediator families, resolvins and protectins, are biosynthesized from EPA and DHA, act locally, and possess potent, novel bioactions is of interest to researchers.

Methyl isobutyl ketone

2-Methylpropyl methyl ketone

C6H12O (100.0888)

Methyl isobutyl ketone (MIBK) is an organic solvent. MIBK is among the top ten most popular organic solvents used in industry. MIBK is occasionally found as a volatile component of urine. MIBK in urine is considered as a biological marker of occupational exposure to this solvent. Olfactory perception is significant but adaptation may occur. The typical toxicity effects of MIBK in humans exposed at 50 to 100 ppm are mucous membrane irritation and weak effects on the central nervous system (CNS) such as headache. Visual dysfunction has been reported in workers exposed to a mixture of organic solvents containing MIBK. Memory impairment was detected in clinical observation on a 44-year-old man who had been exposed to MIBK at 100 ppm for more than 10 years. Regarding to the route of absorption, skin penetration of MIBK is substantial. (PMID: 12592578, 17485256, 16464817, 5556886).

Aminomalonic acid

2-aminopropanedioic acid

C3H5NO4 (119.0219)

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].

ammonia

N-acetyl-α-D-glucosamine 1-phosphate

H3N (17.0265)

An azane that consists of a single nitrogen atom covelently bonded to three hydrogen atoms. Ammonia, also known as nh3 or ammonia solution, is a member of the class of compounds known as homogeneous other non-metal compounds. Homogeneous other non-metal compounds are inorganic non-metallic compounds in which the largest atom belongs to the class of other nonmetals. Ammonia can be found in a number of food items such as rose hip, yardlong bean, cereals and cereal products, and ceylon cinnamon, which makes ammonia a potential biomarker for the consumption of these food products. Ammonia can be found primarily in blood, cellular cytoplasm, cerebrospinal fluid (CSF), and urine, as well as throughout all human tissues. Ammonia exists in all eukaryotes, ranging from yeast to humans. In humans, ammonia is involved in several metabolic pathways, some of which include glucose-alanine cycle, phenylalanine and tyrosine metabolism, homocysteine degradation, and d-arginine and d-ornithine metabolism. Ammonia is also involved in several metabolic disorders, some of which include ureidopropionase deficiency, hyperornithinemia-hyperammonemia-homocitrullinuria [hhh-syndrome], non ketotic hyperglycinemia, and beta-mercaptolactate-cysteine disulfiduria. Moreover, ammonia is found to be associated with 3-Hydroxy-3-methylglutaryl-CoA lyase deficiency, 3-Methyl-crotonyl-glycinuria, citrullinemia type I, and short bowel syndrome. Ammonia is a non-carcinogenic (not listed by IARC) potentially toxic compound. Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH3. The simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products . Acute Exposure: EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration. (z)-n-coumaroyl-5-hydroxyanthranilic acid is a member of the class of compounds known as avenanthramides. Avenanthramides are a group of phenolic alkaloids consisting of conjugate of three phenylpropanoids (ferulic, caffeic, or p-coumaric acid) and anthranilic acid (z)-n-coumaroyl-5-hydroxyanthranilic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa).

C50H73N15O11 (1059.5614)

Bradykinin is a vasoactive kinin that is liberated from its substrate kininogen by the action of kallikrein, and is known to be involved in a wide range of biologic processes. It may play an important role in blood pressure regulation and the maintenance of normal blood flow. Moreover, in various pathologic states of the cardiovascular system, it appears to provide protective actions against ischemic injury, ventricular hypertrophy, congestive heart failure, and thrombosis. Bradykinin is a potent vasodilator that acts through endothelial B2 kinin receptors to stimulate the release of nitric oxide and endothelium-derived hyperpolarizing factor. Bradykinin deficiency states may play a role in some forms of hypertension, and a relative deficiency in bradykinin may be a contributing factor to worsening heart failure. Experimental studies revealed that mice lacking the B2 receptor gene were more likely to develop hypertension, cardiac hypertrophy, and myocardial damage. Kinins exert several biologic actions. They are involved in nociception, inflammation, capillary permeability, reactive hyperemia, and stimulation of cellular glucose uptake. Bradykinin is a polypeptide that circulates in the plasma in very low concentrations in comparison with the amount of bradykinin found in various body tissues. Kininogens ([alpha] 2 globulins) are synthesized in the liver and circulate at high concentrations in the plasma. There are two kininogenases that convert kininogens into bradykinin: plasma kallikrein, also known as Fletcher factor, and glandular kallikrein, also known as tissue kallikrein.

Formamide

Ameisensaeureamid

CH3NO (45.0215)

Formamide, also known as methanamide or ameisensaeureamid, belongs to the class of organic compounds known as carboximidic acids. These are organic acids with the general formula RC(=N)-OH (R=H, organic group). Formamide, in its pure state, has been used as an alternative solvent for the electrostatic self-assembly of polymer nanofilms. Formamide exists in all living organisms, ranging from bacteria to humans. Formamide has been detected, but not quantified in several different foods, such as hyssops, rose hips, asian pears, brassicas, and green bell peppers. It has been used as a softener for paper and fiber. Inhalation of large amounts of formamide vapor may require medical attention. In the past, formamide was produced by treating formic acid with ammonia, which produces ammonium formate, which in turn yields formamide upon heating:HCOOH + NH3 → HCOO−NH+4HCOO−NH+4 → HCONH2 + H2O. Formamide is also generated by aminolysis of ethyl formate: HCOOCH2CH3 + NH3 → HCONH2 + CH3CH2OH. The current industrial process for the manufacture of formamide involves either the carbonylation of ammonia: CO + NH3 → HCONH2. An alternative two-stage process involves the ammonolysis of methyl formate, which is formed from carbon monoxide and methanol: CO + CH3OH → HCOOCH3HCO2CH3 + NH3 → HCONH2 + CH3OH. Formamide is used in the industrial production of hydrogen cyanide. Formamide has been shown to exhibit hematoxicity in animals and is considered hazardous by prolonged exposure through inhalation, oral intake and dermal absorption. Formamide is a metabolite used for biological monitoring of workers exposed to N-N-dimethylformamide (DMF).(PMID 7622279).

Nitric oxide

Endothelium-derived relaxing factor

NO (29.998)

The biologically active molecule nitric oxide (NO) is a simple, membrane-permeable gas with unique chemistry. It is formed by the conversion of L-arginine to L-citrulline, with the release of NO. The enzymatic oxidation of L-arginine to L-citrulline takes place in the presence of oxygen and NADPH using flavin adenine dinucleotide (FAD), flavin mononucleotide (FMN), heme, thiol, and tetrahydrobiopterin as cofactors. The enzyme responsible for the generation of NO is nitric oxide synthase (E.C. 1.7.99.7; NOS). Three NOS isoforms have been described and shown to be encoded on three distinct genes: neuronal NOS (nNOS, NOS type I), inducible NOS (NOS type II), and endothelial NOS (eNOS, NOS type III). Two of them are constitutively expressed and dependent on the presence of calcium ions and calmodulin to function (nNOS and eNOS), while iNOS is considered non-constitutive and calcium-independent. However, experience has shown that constitutive expression of nNOS and eNOS is not as rigid as previously thought (i.e. either present or absent), but can be dynamically controlled during development and in response to injury. Functionally, NO may act as a hormone, neurotransmitter, paracrine messenger, mediator, cytoprotective molecule, and cytotoxic molecule. NO has multiple cellular molecular targets. It influences the activity of transcription factors, modulates upstream signaling cascades, mRNA stability and translation, and processes the primary gene products. In the brain, many processes are linked to NO. NO activates its receptor, soluble guanylate cyclase by binding to it. The stimulation of this enzyme leads to increased synthesis of the second messenger, cGMP, which in turn activates cGMP-dependent kinases in target cells. NO exerts a strong influence on glutamatergic neurotransmission by directly interacting with the N-methyl-D-aspartate (NMDA) receptor. Neuronal NOS is connected to NMDA receptors (see below) and sharply increases NO production following activation of this receptor. Thus, the level of endogenously produced NO around NMDA synapses reflects the activity of glutamate-mediated neurotransmission. However, there is recent evidence showing that non-NMDA glutamate receptors (i.e. AMPA and type I metabotropic receptors) also contribute to NO generation. Besides its influence on glutamate, NO is known to have effects on the storage, uptake and/or release of most other neurotransmitters in the CNS (acetylcholine, dopamine, noradrenaline, GABA, taurine, and glycine) as well as of certain neuropeptides. Finally, since NO is a highly diffusible molecule, it may reach extrasynaptic receptors at target cell membranes that are some distance away from the place of NO synthesis. NO is thus capable of mediating both synaptic and nonsynaptic communication processes. NO is a potent vasodilator (a major endogenous regulator of vascular tone), and an important endothelium-dependent relaxing factor. NO is synthesized by NO synthases (NOS) and NOS are inhibited by asymmetrical dimethylarginine (ADMA). ADMA is metabolized by dimethylarginine dimethylaminohydrolase (DDAH) and excreted in the kidneys. Lower ADMA levels in pregnant women compared to non-pregnant controls suggest that ADMA has a role in vascular dilatation and blood pressure changes. Several studies show an increase in ADMA levels in pregnancies complicated with preeclampsia. Elevated ADMA levels in preeclampsia are seen before clinical symptoms have developed; these findings suggest that ADMA has a role in the pathogenesis of preeclampsia. In some pulmonary hypertensive states such as ARDS, the production of endogenous NO may be impaired. Nitric oxide inhalation selectively dilates the pulmonary circulation. Significant systemic vasodilation does not occur because NO is inactivated by rapidly binding to hemoglobin. In an injured lung with pulmonary hypertension, inhaled NO produces local vasodilation of well-ventilated lung units and may "steal" blood flow away from unventil...

N1-Acetylspermidine

N-(3-((4-Aminobutyl)amino)propyl)-acetamide

N1-Acetylspermidine is a polyamine. In many organisms, polyamines originate from L-ornithine and methionine. Ornithine decarboxylase (EC 4.1.1.17), a key enzyme in polyamine metabolism, decarboxylates L-ornithine to yield putrescine which is then converted to higher polyamines spermidine and spermine by successive addition of aminopropyl groups derived from decarboxylated S-adenosylmethionine. Aliphatic polyamines occur ubiquitously in organisms and have important functions in the stabilization of cell membranes, biosynthesis of informing molecules, cell growth and differentiation, as well as adaptation to osmotic, ionic, pH and thermal stress. These cationic substances are implicated in multiple functions, therefore it is not surprising that intracellular levels of polyamines are regulated by different mechanisms. The inhibition of polyamine metabolism has important pharmacological and therapeutic implications for the control of physiological processes, reproduction, cancer and parasitic diseases. Recent reports have suggested the idea that parasites with an high turnover of Ornithine Decarboxilase (ODC) are resistant to Difluoromethyl ornithine (DFMO, the irreversible inhibitor of ornithine decarboxylase) because they always contain a fraction of newly synthesized and active enzyme, therefore not DFMO inhibited, sufficient to produce small amounts of putrescine rapidly converted into spermidine, which can support protozoan proliferation. DFMO has proved to be curative in trypanosomiasis, coccidiosis, and certain other protozoan infections. (PMID: 15490259). N1-Acetylspermidine is a polyamine.

Nitrogen

Molecular nitrogen

N2 (28.0061)

Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78\\% by volume of Earths atmosphere. Nitrogen occurs in all living organisms. It is a constituent element of amino acids and therefore of proteins and nucleic acids (DNA and RNA). Nitrogen is found in the chemical structure of almost all neurotransmitters and is a key component of alkaloids. Specific bacteria (e.g. Rhizobium trifolium) possess nitrogenase enzymes which can fix atmospheric nitrogen into a form (ammonium ion) which is chemically useful to higher organisms. Animals use nitrogen-containing amino acids from plant sources, as starting materials for all nitrogen-compound animal biochemistry, including the manufacture of proteins and nucleic acids. Animal metabolism of NO (nitric oxide) results in production of nitrite. Animal metabolism of nitrogen in proteins generally results in excretion of urea, while animal metabolism of nucleic acids results in excretion of urea and uric acid. The characteristic odor of animal flesh decay is caused by nitrogen-containing long-chain amines, such as putrescine and cadaverine. Decay of organisms and their waste products may produce small amounts of nitrate, but most decay eventually returns nitrogen content to the atmosphere, as molecular nitrogen. The circulation of nitrogen from the atmosphere through organics and then back to the atmosphere is commonly referred to as the nitrogen cycle. Nitrogen can be measured in urine with the Kjeldahl method or by spectrophotometric methods (enzymic tests). Total urinary nitrogen is calculated based on urea urinary nitrogen quantified with these methods.

L-Glutamic gamma-semialdehyde

Glutamic acid gamma-semialdehyde, (L)-isomer

L-glutamic-gamma-semialdehyde, also known as 5-oxo-L-norvaline or glutamic acid gamma-semialdehyde, (L)-isomer, 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-glutamic-gamma-semialdehyde is soluble (in water) and a moderately acidic compound (based on its pKa). L-glutamic-gamma-semialdehyde can be found in a number of food items such as rubus (blackberry, raspberry), jackfruit, loganberry, and plains prickly pear, which makes L-glutamic-gamma-semialdehyde a potential biomarker for the consumption of these food products. L-glutamic-gamma-semialdehyde exists in all living species, ranging from bacteria to humans. In humans, L-glutamic-gamma-semialdehyde is involved in the arginine and proline metabolism. L-glutamic-gamma-semialdehyde is also involved in several metabolic disorders, some of which include hyperornithinemia-hyperammonemia-homocitrullinuria [hhh-syndrome], prolidase deficiency (PD), arginine: glycine amidinotransferase deficiency (AGAT deficiency), and ornithine aminotransferase deficiency (OAT deficiency). Glutamic gamma-semialdehyde is the metabolic precursor for proline biosynthesis. The conversion from L-Glutamate, an ATP- and NADPH-dependent reaction, is catalyzed by the enzyme Delta-1-pyrroline-5-carboxylate synthetase (P5CS) (OMIM 138250). L-Glutamic-gamma-semialdehyde can also be converted to or be formed from the amino acids L-ornithine (EC 2.6.1.13) and L-proline (EC 1.5.99.8 and EC 1.5.1.2). It is also one of the few metabolites that can be a precursor to other metabolites of both the urea cycle and the citric acid cycle (BioCyc).

Ethyl carbamate

Urethane + ethanol (combination)

C3H7NO2 (89.0477)

Ethyl carbamate, also known as aethylurethan or uretan, belongs to the class of organic compounds known as carboximidic acids and derivatives. Carboximidic acids and derivatives are compounds containing a carboximidic group, with the general formula R-C(=NR1)OR2. Ethyl carbamate has been detected, but not quantified, in alcoholic beverages. This could make ethyl carbamate a potential biomarker for the consumption of these foods. Ethyl carbamate is formally rated as a probable carcinogen (by IARC 2A) and is also a potentially toxic compound. It is readily absorbed from the gastrointestinal tract and the skin. It also tends to induce specific mutations in the Kras oncogene in codon 61 of exon 2 including A:T transversions and A-->G transitions in the second base and A-->T transversions in the third base. Urethane, formerly marketed as an inactive ingredient in Profenil injection, was determined to be carcinogenic and was removed from the Canadian, US, and UK markets in 1963. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. In case of contact with eyes, irrigate opened eyes for several minutes under running water. Metabolism is mediated by cytochrome P450 2E1.

N-Methylputrescine

N1-Methyl-1,4-butanediamine

N-Methylputrescine is a byproduct of putrescine (a diamine), via methylation by putrescine N-methyltransferase (PMT; EC 2.1.1.53). N-methylputrescine is able to affect protein synthesis to a small extent in stimulated H-35 hepatoma cells, being an inhibitor of cellular insulin-induced ornithine decarboxylase activity. (PMID: 2051998). 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-Methylputrescine is a microbial metabolite.

Kyotorphin (L-tyrosyl-L-arginine) is a neuroactive dipeptide which plays a role in pain regulation in the brain. It was first isolated from bovine brain by Japanese scientists in 1979. Kyotorphin was named for the site of its discovery, Kyoto, Japan and because of its morphine- (or endorphin-) like analgesic activity. Kyotorphin has an analgesic effect, but it does not interact with the opioid receptors. Instead, it acts by releasing an Met-enkephalin and stabilizing it from degradation. It may also possess properties of neuromediator/neuromodulator. It has been shown that kyotorphin is present in the human cerebrospinal fluid and that it is lower in patients with persistent pain.

5-Androstenediol is a direct metabolite of the most abundant steroid produced by the human adrenal cortex, dehydroepiandrosterone (DHEA). 5-Androstenediol is less androgenic than 4-androstenediol, and stimulates the immune system. When administered to rats in vivo, 5-androstenediol has approximately 1/70 the androgenicity of DHEA, 1/185 the androgenicity of androstenedione, and 1/475 the androgenicity of testosterone (Wikipedia). Because it induces production of white blood cells and platelets, 5-androstenediol is being developed as a radiation countermeasure as Neumune (HE2100). An intermediate in testosterone biosynthesis, found in the testis or the adrenal glands. 5-Androstenediol, derived from dehydroepiandrosterone by the reduction of the 17-keto group (17-hydroxysteroid dehydrogenases), is converted to testosterone by the oxidation of the 3-beta hydroxyl group to a 3-keto group (3-fydroxysteroid dehydrogenase). Androstenediol is a term used to refer to two different steroids with molecular weights of 290.44: 4-androstenediol (4-androstene-3beta,17beta-diol) and 5-androstenediol (5-androstene-3beta,17beta-diol). 4-Androstenediol is closer to testosterone structurally, and has androgenic effects. 5-Androstenediol is a direct metabolite of the most abundant steroid produced by the human adrenal cortex, dehydroepiandrosterone (DHEA). 5-Androstenediol is less androgenic than 4-androstenediol, and stimulates the immune system.

Phycocyanobilin

(2R,3Z)-Phycocyanobilin

C33H38N4O6 (586.2791)

Phycocyanobilin is a linear, open-chain tetrapyrrole pigment that belongs to the family of bilins. It serves as a chromophore in various phytochrome photoreceptors found in cyanobacteria, as well as in the chlorosomes of green sulfur bacteria. Phycocyanobilin is a key component of phycobiliproteins, which are water-soluble pigments involved in light harvesting during photosynthesis. **Chemical Structure:** Phycocyanobilin has a molecular formula of C33H36N4O6 and a molecular weight of approximately 596.67 g/mol. Structurally, it consists of a porphyrin backbone with four pyrrole rings connected by methine bridges. The pyrrole rings contain nitrogen atoms that coordinate a central magnesium ion in phycobiliproteins. Unlike chlorophyll, phycocyanobilin has an open-chain structure due to the presence of a double bond between the C-20 and C-21 positions of the macrocyclic ring, which prevents it from forming a fully circular porphyrin ring. **Properties:** - **Color:** Phycocyanobilin imparts a blue color to the phycobiliproteins in which it is bound. The specific color is due to the electronic structure of the phycocyanobilin molecule, which allows it to absorb light in the red region of the visible spectrum, typically around 620-630 nm. - **Solubility:** Unlike many other pigments, phycocyanobilin is water-soluble due to its binding to phycobiliproteins, which enhances its functionality in the thylakoid membranes of cyanobacteria. - **Chemical Reactivity:** Phycocyanobilin can be isomerized and oxidized to form other bilins, such as phycoerythrobilin and phycourobilin, which have different spectral properties and can be found in different phycobiliproteins. **Biological Role:** Phycocyanobilin plays a critical role in the photosynthetic process of cyanobacteria and certain green sulfur bacteria. Its primary functions include: - **Light Harvesting:** In phycobiliproteins like phycocyanin, phycocyanobilin serves as a light-harvesting antenna. It absorbs light energy and transfers it to the photosynthetic reaction centers, where it is used to drive the synthesis of ATP and NADPH. - **Photoregulation:** In cyanobacteria, phycocyanobilin is also involved in the regulation of photosynthesis through the action of phytochrome-like photoreceptors. These photoreceptors can switch between a Pr (red-absorbing) and a Pfr (far-red-absorbing) form in response to light, regulating gene expression and various metabolic processes. **Synthesis:** Phycocyanobilin is synthesized from the amino acid L-arginine through a series of enzymatic reactions that include the production of 5-aminolevulinic acid (ALA), which is then transformed into protoporphyrin IX. The protoporphyrin IX is subsequently modified to form phycocyanobilin, a process that involves the removal of the macrocyclic ring and the introduction of the double bond at the C-20 and C-21 positions. In summary, phycocyanobilin is an essential pigment for the photosynthetic apparatus of certain photosynthetic organisms, contributing to their ability to capture and utilize light energy for the production of organic compounds. Its unique structure and properties allow it to perform a variety of functions that are critical to the survival and ecological success of these organisms.

N(omega)-Hydroxyarginine

(2S)-2-amino-5-[(Z)-N-hydroxycarbamimidamido]pentanoic acid

C6H14N4O3 (190.1066)

N-omega-hydroxy-l-arginine, also known as 6-noha, belongs to arginine and derivatives class of compounds. Those are compounds containing arginine or a derivative thereof resulting from reaction of arginine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-omega-hydroxy-l-arginine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). N-omega-hydroxy-l-arginine can be found in a number of food items such as chinese cinnamon, chervil, sugar apple, and safflower, which makes N-omega-hydroxy-l-arginine a potential biomarker for the consumption of these food products. N(omega)-Hydroxyarginine is a product of the arginine-nitric oxide pathway, and is the first intermediate in the process catalyzed by nitric oxide synthase (NOS) (EC 1.14.13.99). NOS is a heme protein that catalyzes the oxygenation of L-arginine in the presence of NADPH to form nitric oxide and citrulline. N(omega)-Hydroxyarginine appears to interfere with cell proliferation/cell growth by inhibiting arginase, a binuclear Mn(2+) metalloenzyme that catalyzes the hydrolysis of L-arginine to L-ornithine and urea (EC 3.5.3.1). Arginase has 6R-tetrahydrobiopterin (H4B) as an enzyme-bound cofactor (PMID: 11259671, 11258880, 14504282, 9735327).

Lipoxin B4

(5S,14R,6E,8Z,10E,12E,15S)-5,14,15-Trihydroxy-6,8,10,12-eicosatetraenoic acid

Lipoxins (LXs) and aspirin-triggered lipoxin (ATL) are trihydroxytetraene-containing eicosanoids generated from arachidonic acid that are distinct in structure, formation, and function from the many other proinflammatory lipid-derived mediators. These endogenous eicosanoids have now emerged as founding members of the first class of lipid/chemical mediators involved in the resolution of the inflammatory response. Lipoxin A4 (LXA4), ATL, and their metabolic stable analogs elicit cellular responses and regulate leukocyte trafficking in vivo by activating the specific receptor, ALX. Many of the eicosanoids derived from arachidonic acid (AA2), including prostaglandins (PGs) and leukotrienes (LTs), play important roles as local mediators exerting a wide range of actions relevant in immune hypersensitivity and inflammation. However, recent observations indicate that other agents derived from the lipoxygenase (LO) pathways are formed and play a key role in initiating the resolution of acute inflammation. This phenomenon is an active process that is governed by specific lipid mediators and involves a series of well-orchestrated temporal events. Thus, potent locally released mediators serve as checkpoint controllers of inflammation. In addition to the well-appreciated ability of aspirin to inhibit PGs, aspirin also acetylates cyclooxygenase (COX)-2, triggering the formation of a 15-epimeric form of lipoxins, termed aspirin-triggered LXA4 (ATL). These eicosanoids (i.e. LXA4 and ATL) with a unique trihydroxytetraene structure function as stop signals in inflammation and actively participate in dampening host responses to bring the inflammation to a close, namely, resolution. LXA4 and ATL elicit the multicellular responses via a specific G protein-coupled receptor (GPCR) termed ALX that has been identified in human (PMID: 16968948, 11478982). Lipoxins (LXs) and aspirin-triggered Lipoxin (ATL) are trihydroxytetraene-containing eicosanoids generated from arachidonic acid that are distinct in structure, formation, and function from the many other proinflammatory lipid-derived mediators. These endogenous eicosanoids have now emerged as founding members of the first class of lipid/chemical mediators involved in the resolution of the inflammatory response. Lipoxin A4 (LXA4), ATL, and their metabolic stable analogs elicit cellular responses and regulate leukocyte trafficking in vivo by activating the specific receptor, ALX.

Angiotensin III (AngIII) is one of the N-terminal angiotensin degradation products of angiotensin II. AngIII shares some of its properties with Ang II, including chemotaxis and production of growth factors and chemokines. AngIII generated within the brain acts within neural circuits of the central nervous system to regulate body fluid balance. The stimulation of vasopressin release by AngIII is thought to be one of the mechanisms by which AngIII controls volume homeostasis under conditions of hypovolemia, by reducing renal water loss and increasing blood pressure. Brain aminopeptidase A, the enzyme forming central AngIII, could constitute a putative central therapeutic target for the treatment of hypertension.

Those are compounds containing proline or a derivative thereof resulting from reaction of proline at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Proline is soluble (in water) and a moderately acidic compound (based on its pKa). Proline can be found in a number of food items such as yellow zucchini, swiss chard, spinach, and cucumber, which makes proline a potential biomarker for the consumption of these food products.

3,4-dihydro-2H-pyrrole-2-carboxylic acid

A 1-pyrrolinecarboxylic acid that is 1-pyrroline in which one of the hydrogens at position 5 is replaced by a carboxy group. The stereoisomer (S)-1-pyrroline-5-carboxylate (also referred to as L-P5C) is an intermediate metabolite in the biosynthesis and degradation of proline and arginine.[4][5][6] In prokaryotic proline biosynthesis, GSA is synthesized from γ-glutamyl phosphate by the enzyme γ-glutamyl phosphate reductase. In most eukaryotes, GSA is synthesised from the amino acid glutamate by the bifunctional enzyme 1-pyrroline-5-carboxylate synthase (P5CS). The human P5CS is encoded by the ALDH18A1 gene.[7][8] The enzyme pyrroline-5-carboxylate reductase converts P5C into proline. In proline degradation, the enzyme proline dehydrogenase produces P5C from proline, and the enzyme 1-pyrroline-5-carboxylate dehydrogenase converts GSA to glutamate. In many prokaryotes, proline dehydrogenase and P5C dehydrogenase form a bifunctional enzyme that prevents the release of P5C during proline degradation. 1-Pyrroline-5-carboxylic acid.

Biopterin

2-amino-6-[(1R,2S)-1,2-dihydroxypropyl]-4,8-dihydropteridin-4-one

Biopterin concentrations in cerebrospinal fluid from patients with Parkinsons disease, in which the nigrostriatal dopamine neurons degenerate, are lower than those from age-matched older controls. In hereditary progressive dystonia/DOPA-responsive dystonia, which is a dopamine deficiency caused by mutations in GTP cyclohydrolase I without neuronal cell death (Segawas disease), biopterin in cerebrospinal fluid decrease in parallel owing to the decreased activity in GTP cyclohydrolase I (EC 3.5.4.16, is an enzyme that is part of the folate and biopterin biosynthesis pathways. It is responsible for the hydrolysis of guanosine triphosphate (GTP) to form 7,8-dihydroneopterin 3-triphosphate. (Pteridines (1999), 10(1), 5-13.) Lowered levels of urinary biopterin concomitant with elevated serum phenylalanine concentration occur in a variant type of hyperphenylalaninemia caused by a deficiency of tetrahydrobiopterin (BH4), the obligatory cofactor for phenylalanine hydroxylase. The most frequent form of this cofactor deficiency is due to lack of 6-pyruvoyl-tetrahydropterin synthase (PTPS) activity, the second enzyme in the biosynthetic pathway for BH4. (PMID 8178819) The hepatic phenylalanine hydroxylating system consists of 3 essential components, phenylalanine hydroxylase, dihydropteridine reductase, and the nonprotein coenzyme, tetrahydrobiopterin. The reductase and the pterin coenzyme are also essential components of the tyrosine and tryptophan hydroxylating systems. There are 3 distinct forms of phenylketonuria or hyperphenylalaninemia, each caused by lack of 1 of these essential components. The variant forms of the disease that are caused by the lack of dihydropteridine reductase or tetrahydrobiopterin are characterized by severe neurol. deterioration, impaired functioning of tyrosine and tryptophan hydroxylases, and the resultant deficiency of tyrosine- and tryptophan-derived monoamine neurotransmitters in brain. (PMID 3930837) [HMDB] Biopterin, also known as tetrahydrobiopterin or BH4, belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative. Biopterin or tetrahydrobiopterin is also classified as a pterin derivative that consists of pterin group bearing an amino, an oxo and a 1,2-dihydroxypropyl substituent at positions 2, 4 and 6, respectively. Biopterin compounds found within the animals include BH4 (tetrahydrobiopterin), the free radical BH3, and BH2 (also a free radical, called Dihydrobiopterin). BH2 is produced in the synthesis of L-DOPA, dopamine, norepinephrine and epinephrine. It is restored to the required cofactor tetrahydrobiopterin by the enzyme dihydrobiopterin reductase. Tetrahydrobiopterin (BH4) is a cofactor of the three aromatic amino acid hydroxylase enzymes, used in the degradation of amino acid phenylalanine and in the biosynthesis of the neurotransmitters serotonin (5-hydroxytryptamine, 5-HT), melatonin, dopamine, norepinephrine (noradrenaline), epinephrine (adrenaline). It is also a cofactor for the production of nitric oxide (NO) by the nitric oxide syntheses. Tetrahydrobiopterin is biosynthesized from guanosine triphosphate (GTP) by three chemical reactions mediated by the enzymes GTP cyclohydrolase I (GTPCH), 6-pyruvoyltetrahydropterin synthase (PTPS), and sepiapterin reductase (SR). Biopterin synthesis disorders are a cause of hyperphenylalaninemia. There are 3 distinct forms of phenylketonuria or hyperphenylalaninemia, each caused by lack of aromatic amino acid hydroxylase enzymes. The variant forms of hyperphenylalaninemia that are caused by the lack of dihydropteridine reductase or tetrahydrobiopterin are characterized by severe neurological deterioration, impaired functioning of tyrosine and tryptophan hydroxylases, and the resultant deficiency of tyrosine- and tryptophan-derived monoamine neurotransmitters in brain. (PMID 3930837). 6-Biopterin (L-Biopterin), a pterin derivative, is a NO synthase cofactor.

These are coenzymes containing a 2-amino-pteridine-4-one derivative. They are synthesized in several parts of the body, including the pineal gland. 7,8-Dihydroneopterin is a strong basic compound (based on its pKa). Within humans, 7,8-dihydroneopterin participates in a number of enzymatic reactions. In particular, 7,8-dihydroneopterin can be biosynthesized from sepiapterin; which is catalyzed by the enzyme sepiapterin reductase or carbonyl reductase [NADPH] 1. In humans, 7,8-dihydroneopterin is involved in the metabolic disorder called hyperphenylalaninemia due to 6-pyruvoyltetrahydropterin synthase (PTPS) deficiency. 7,8-Dihydroneopterin is produced by human monocyte-derived macrophages upon stimulation with interferon-gamma. Increased amounts of 7,8-dihydroneopterin in human body fluids are found in many disorders, including viral infections and autoimmune diseases (PMID: 12804528). 7,8-dihydroneopterin, also known as npr, belongs to biopterins and derivatives class of compounds. Those are coenzymes containing a 2-amino-pteridine-4-one derivative. They are mainly synthesized in several parts of the body, including the pineal gland. 7,8-dihydroneopterin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 7,8-dihydroneopterin can be found in a number of food items such as prickly pear, star anise, cocoa bean, and black salsify, which makes 7,8-dihydroneopterin a potential biomarker for the consumption of these food products. 7,8-dihydroneopterin exists in all living organisms, ranging from bacteria to humans. In humans, 7,8-dihydroneopterin is involved in the pterine biosynthesis. 7,8-dihydroneopterin is also involved in several metabolic disorders, some of which include hyperphenylalaninemia due to dhpr-deficiency, sepiapterin reductase deficiency, dopa-responsive dystonia, and hyperphenylalaniemia due to guanosine triphosphate cyclohydrolase deficiency. 7,8-Dihydroneopterin, an inflammation marker, induces cellular apoptosis in astrocytes and neurons via enhancement of nitric oxide synthase (iNOS) expression. 7,8-Dihydroneopterin can be used in the research of neurodegenerative diseases[1].

Ammonia

Ammonia (CONC 20\\% or greater)

H3N (17.0265)

Ammonia is a colourless alkaline gas and is one of the most abundant nitrogen-containing compounds in the atmosphere. It is an irritant with a characteristic pungent odor that is widely used in industry. Inasmuch as ammonia is highly soluble in water and, upon inhalation, is deposited in the upper airways, occupational exposures to ammonia have commonly been associated with sinusitis, upper airway irritation, and eye irritation. Acute exposures to high levels of ammonia have also been associated with diseases of the lower airways and interstitial lung. Small amounts of ammonia are naturally formed in nearly all tissues and organs of the vertebrate organism. Ammonia is both a neurotoxin and a metabotoxin. In fact, it is the most common endogenous neurotoxin. A neurotoxin is a compound that causes damage to neural tissue and neural cells. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Ammonia is recognized to be central in the pathogenesis of a brain condition known as hepatic encephalopathy, which arises from various liver diseases and leads to a build up ammonia in the blood (hyperammonemia). More than 40\\% of people with cirrhosis develop hepatic encephalopathy. Part of the neurotoxicity of ammonia arises from the fact that it easily crosses the blood-brain barrier and is absorbed and metabolized by the astrocytes, a population of cells in the brain that constitutes 30\\% of the cerebral cortex. Astrocytes use ammonia when synthesizing glutamine from glutamate. The increased levels of glutamine lead to an increase in osmotic pressure in the astrocytes, which become swollen. There is increased activity of the inhibitory gamma-aminobutyric acid (GABA) system, and the energy supply to other brain cells is decreased. This can be thought of as an example of brain edema. The source of the ammonia leading to hepatic encaphlopahy is not entirely clear. The gut produces ammonia, which is metabolized in the liver, and almost all organ systems are involved in ammonia metabolism. Colonic bacteria produce ammonia by splitting urea and other amino acids, however this does not fully explain hyperammonemia and hepatic encephalopathy. The alternative explanation is that hyperammonemia is the result of intestinal breakdown of amino acids, especially glutamine. The intestines have significant glutaminase activity, predominantly located in the enterocytes. On the other hand, intestinal tissues only have a little glutamine synthetase activity, making it a major glutamine-consuming organ. In addition to the intestine, the kidney is an important source of blood ammonia in patients with liver disease. Ammonia is also taken up by the muscle and brain in hepatic coma, and there is confirmation that ammonia is metabolized in muscle. Excessive formation of ammonia in the brains of Alzheimers disease patients has also been demonstrated, and it has been shown that some Alzheimers disease patients exhibit elevated blood ammonia concentrations. Ammonia is the most important natural modulator of lysosomal protein processing. Indeed, there is strong evidence for the involvement of aberrant lysosomal processing of beta-amyloid precursor protein (beta-APP) in the formation of amyloid deposits. Inflammatory processes and activation of microglia are widely believed to be implicated in the pathology of Alzheimers disease. Ammonia is able to affect the characteristic functions of microglia, such as endocytosis, and cytokine production. Based on these facts, an ammonia-based hypothesis for Alzheimers disease has been suggested (PMID: 17006913, 16167195, 15377862, 15369278). Chronically high levels of ammonia in the blood are associated with nearly twenty different inborn errors of metabolism including: 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, 3-methyl-crotonylglycinuria, argininemia, argininosuccinic aciduria, beta-ketothiolase deficiency, biotinidase deficiency, carbamoyl phosphate synthetase... Ammonia is a colourless gas with a characteristic pungent odour. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceuticals. Although in wide use, ammonia is both caustic and hazardous. Ammonia is found in many foods, some of which are spinach, common beet, ucuhuba, and oriental wheat.

Indoleacrylic acid

(2E)-3-(1H-indol-3-yl)prop-2-enoic acid

C11H9NO2 (187.0633)

Indoleacrylic acid (CAS: 1204-06-4), also known as indoleacrylate, IA, and IAcrA, is a member of the class of compounds known as indoles. Indoles are compounds containing an indole moiety, which consists of pyrrole ring fused to benzene to form 2,3-benzopyrrole. Indoleacrylic acid is practically insoluble (in water) and a weak acidic compound (based on its pKa). Within the cell, indoleacrylic acid is primarily located in the membrane (predicted from logP). Indoleacrylic acid is best known as a plant growth hormone (a natural auxin), whereas its biological role in animals is still unknown. A two-stage production of this compound is likely: intestinal microorganisms catabolize tryptophan to indole derivatives which are then absorbed and converted into indoleacrylic acid and its glycine conjugate, indolylacryloylglycine (IAcrGly). Indolylacryloylglycine excretion in urine is especially pronounced in some myopathies, namely in boys with Duchenne muscular dystrophy (PMID: 10707769). It has been recently found that indoleacrylic acid promotes intestinal epithelial barrier function and mitigates inflammatory responses. Stimulating indoleacrylic acid production could promote anti-inflammatory responses and have therapeutic benefits (PMID: 28704649). Urinary Indole-3-acrylate is produced by Clostridium sporogenes (PMID: 29168502). Indoleacrylic acid is also a metabolite of Peptostreptococcus (PMID: 28704649, 29168502). trans-3-Indoleacrylic acid is an endogenous metabolite.

It is the precursor to ferulic acid, coniferyl alcohol, and sinapyl alcohol, all of which are significant building blocks in lignin. Outside of the human body, caffeic acid has been detected, but not quantified in fats and oils and nuts. Caffeic acid is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Caffeic acid has a variety of potential pharmacological effects in in vitro studies and in animal models, and the inhibitory effect of caffeic acid on cancer cell proliferation by an oxidative mechanism in the human HT-1080 fibrosarcoma cell line has recently been established. It occurs at high levels in black chokeberry (141 mg per 100 g) and in fairly high level in lingonberry (6 mg per 100 g).

Has no odor. pH (of 5\\% solution): 4-5.5. Slightly efflorescent in dry air. Bitter, acrid taste. (NTP, 1992) Scopolamine is a tropane alkaloid that is the (S)-tropic acid ester of 6beta,7beta-epoxy-1alphaH,5alphaH-tropan-3alpha-ol. It has a role as a muscarinic antagonist, an antiemetic, an adjuvant, a mydriatic agent, an antispasmodic drug, an anaesthesia adjuvant, an antidepressant and a metabolite. It is a propanoate ester, an epoxide, a tertiary amino compound and a tropane alkaloid. It is functionally related to a (S)-tropic acid. It is a conjugate base of a scopolamine(1+). Scopolamine is a tropane alkaloid isolated from members of the Solanaceae family of plants, similar to [atropine] and [hyoscyamine], all of which structurally mimic the natural neurotransmitter [acetylcholine]. Scopolamine was first synthesized in 1959, but to date, synthesis remains less efficient than extracting scopolamine from plants. As an acetylcholine analogue, scopolamine can antagonize muscarinic acetylcholine receptors (mAChRs) in the central nervous system and throughout the body, inducing several therapeutic and adverse effects related to alteration of parasympathetic nervous system and cholinergic signalling. Due to its dose-dependent adverse effects, scopolamine was the first drug to be offered commercially as a transdermal delivery system, Scopoderm TTS®, in 1981. As a result of its anticholinergic effects, scopolamine is being investigated for diverse therapeutic applications; currently, it is approved for the prevention of nausea and vomiting associated with motion sickness and surgical procedures. Scopolamine was first approved by the FDA on December 31, 1979, and is currently available as both oral tablets and a transdermal delivery system. Scopolamine is an Anticholinergic. The mechanism of action of scopolamine is as a Cholinergic Antagonist. Hyoscine is a natural product found in Duboisia leichhardtii, Duboisia myoporoides, and other organisms with data available. Scopolamine is a tropane alkaloid derived from plants of the nightshade family (Solanaceae), specifically Hyoscyamus niger and Atropa belladonna, with anticholinergic, antiemetic and antivertigo properties. Structurally similar to acetylcholine, scopolamine antagonizes acetylcholine activity mediated by muscarinic receptors located on structures innervated by postganglionic cholinergic nerves as well as on smooth muscles that respond to acetylcholine but lack cholinergic innervation. The agent is used to cause mydriasis, cycloplegia, to control the secretion of saliva and gastric acid, to slow gut motility, and prevent vomiting. An alkaloid from SOLANACEAE, especially DATURA and SCOPOLIA. Scopolamine and its quaternary derivatives act as antimuscarinics like ATROPINE, but may have more central nervous system effects. Its many uses include an anesthetic premedication, the treatment of URINARY INCONTINENCE and MOTION SICKNESS, an antispasmodic, and a mydriatic and cycloplegic. A tropane alkaloid that is the (S)-tropic acid ester of 6beta,7beta-epoxy-1alphaH,5alphaH-tropan-3alpha-ol.

An alpha-amino acid that consists of butyric acid bearing an amino substituent at position 2 and a carbamoyl substituent at position 4. Glutamine (symbol Gln or Q)[4] is an α-amino acid that is used in the biosynthesis of proteins. Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide. It is classified as a charge-neutral, polar amino acid. It is non-essential and conditionally essential in humans, meaning the body can usually synthesize sufficient amounts of it, but in some instances of stress, the body's demand for glutamine increases, and glutamine must be obtained from the diet.[5][6] It is encoded by the codons CAA and CAG. It is named after glutamic acid, which in turn is named after its discovery in cereal proteins, gluten.[7] In human blood, glutamine is the most abundant free amino acid.[8] The dietary sources of glutamine include especially the protein-rich foods like beef, chicken, fish, dairy products, eggs, vegetables like beans, beets, cabbage, spinach, carrots, parsley, vegetable juices and also in wheat, papaya, Brussels sprouts, celery, kale and fermented foods like miso. The one-letter symbol Q for glutamine was assigned in alphabetical sequence to N for asparagine, being larger by merely one methylene –CH2– group. Note that P was used for proline, and O was avoided due to similarity with D. The mnemonic Qlutamine was also proposed.[7] A - Alimentary tract and metabolism > A16 - Other alimentary tract and metabolism products > A16A - Other alimentary tract and metabolism products > A16AA - Amino acids and derivatives COVID info from COVID-19 Disease Map, PDB, Protein Data Bank, clinicaltrial, clinicaltrials, clinical trial, clinical trials Corona-virus Coronavirus SARS-CoV-2 COVID-19 SARS-CoV COVID19 SARS2 SARS CONFIDENCE standard compound; INTERNAL_ID 13 Acquisition and generation of the data is financially supported by the Max-Planck-Society L-Glutamine (L-Glutamic acid 5-amide) is a non-essential amino acid present abundantly throughout the body and involved in many metabolic processes.

Caffeic Acid

3,4-dihydroxy cinnamic acid

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. 3,4-dihydroxycinnamic acid, also known as caffeic acid or trans-caffeate, is a member of the class of compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. 3,4-dihydroxycinnamic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 3,4-dihydroxycinnamic acid can be found in fats and oils and nuts, which makes 3,4-dihydroxycinnamic acid a potential biomarker for the consumption of these food products. 3,4-dihydroxycinnamic acid exists in all eukaryotes, ranging from yeast to humans. Caffeic acid is an organic compound that is classified as a hydroxycinnamic acid. This yellow solid consists of both phenolic and acrylic functional groups. It is found in all plants because it is a key intermediate in the biosynthesis of lignin, one of the principal components of plant biomass and its residues .

BENZENEACETIC ACID, .ALPHA.-(HYDROXYMETHYL)-8-METHYL-8-AZABICYCLO(3.2.1)OCT-3-YL ESTER, ENDO-(+/-)-

Atropine is a racemate composed of equimolar concentrations of (S)- and (R)-atropine. It is obtained from deadly nightshade (Atropa belladonna) and other plants of the family Solanaceae. It has a role as a muscarinic antagonist, an anaesthesia adjuvant, an anti-arrhythmia drug, a mydriatic agent, a parasympatholytic, a bronchodilator agent, a plant metabolite, an antidote to sarin poisoning and a oneirogen. It contains a (S)-atropine and a (R)-atropine. Atropine is an alkaloid originally synthesized from Atropa belladonna. It is a racemic mixture of d-and l-hyoscyamine, of which only l-hyoscyamine is pharmacologically active. Atropine is generally available as a sulfate salt and can be administered by intravenous, subcutaneous, intramuscular, intraosseous, endotracheal and ophthalmic methods. Oral atropine is only available in combination products. Atropine is a competitive, reversible antagonist of muscarinic receptors that blocks the effects of acetylcholine and other choline esters. It has a variety of therapeutic applications, including pupil dilation and the treatment of anticholinergic poisoning and symptomatic bradycardia in the absence of reversible causes. Atropine is a relatively inexpensive drug and is included in the World Health Organization List of Essential Medicines. Atropine is an Anticholinergic and Cholinergic Muscarinic Antagonist. The mechanism of action of atropine is as a Cholinergic Antagonist and Cholinergic Muscarinic Antagonist. Hyoscyamine as a natural plant alkaloid derivative and anticholinergic that is used to treat mild to moderate nausea, motion sickness, hyperactive bladder and allergic rhinitis. Hyoscyamine has not been implicated in causing liver enzyme elevations or clinically apparent acute liver injury. Atropine is a natural product found in Cyphanthera tasmanica, Anthocercis ilicifolia, and other organisms with data available. Atropine Sulfate is the sulfate salt of atropine, a naturally-occurring alkaloid isolated from the plant Atropa belladonna. Atropine functions as a sympathetic, competitive antagonist of muscarinic cholinergic receptors, thereby abolishing the effects of parasympathetic stimulation. This agent may induce tachycardia, inhibit secretions, and relax smooth muscles. (NCI04) Atropine is a synthetically-derived form of the endogenous alkaloid isolated from the plant Atropa belladonna. Atropine functions as a sympathetic, competitive antagonist of muscarinic cholinergic receptors, thereby abolishing the effects of parasympathetic stimulation. This agent may induce tachycardia, inhibit secretions, and relax smooth muscles. (NCI04) Hyoscyamine is a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity. Hyoscyamine functions as a non-selective, competitive antagonist of muscarinic receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal tract. These inhibitory effects cause a decrease in saliva, bronchial mucus, gastric juices, and sweat. Furthermore, its inhibitory action on smooth muscle prevents bladder contraction and decreases gastrointestinal motility. An alkaloid, originally from Atropa belladonna, but found in other plants, mainly SOLANACEAE. Hyoscyamine is the 3(S)-endo isomer of atropine.

Dialkylamines are organic compounds containing a dialkylamine group, characterized by two alkyl groups bonded to the amino nitrogen. Spermidine is soluble (in water) and a very strong basic compound (based on its pKa). Spermidine can be found in radish, which makes spermidine a potential biomarker for the consumption of this food product. Spermidine can be found primarily in most biofluids, including urine, blood, saliva, and feces, as well as throughout most human tissues. Spermidine exists in all living organisms, ranging from bacteria to humans. In humans, spermidine is involved in a couple of metabolic pathways, which include methionine metabolism and spermidine and spermine biosynthesis. Spermidine is also involved in several metabolic disorders, some of which include homocystinuria-megaloblastic anemia due to defect in cobalamin metabolism, cblg complementation type, methionine adenosyltransferase deficiency, s-adenosylhomocysteine (SAH) hydrolase deficiency, and hypermethioninemia. Spermidine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Spermidine is a polyamine compound (C 7H 19N 3) found in ribosomes and living tissues, and having various metabolic functions within organisms. It was originally isolated from semen . As a uremic toxin, this compound can cause uremic syndrome. Uremic syndrome may affect any part of the body and can cause nausea, vomiting, loss of appetite, and weight loss. It can also cause changes in mental status, such as confusion, reduced awareness, agitation, psychosis, seizures, and coma. Abnormal bleeding, such as bleeding spontaneously or profusely from a very minor injury can also occur. Heart problems, such as an irregular heartbeat, inflammation in the sac that surrounds the heart (pericarditis), and increased pressure on the heart can be seen in patients with uremic syndrome. Shortness of breath from fluid buildup in the space between the lungs and the chest wall (pleural effusion) can also be present (T3DB). Spermidine maintains cell membrane stability, increases antioxidant enzymes activities, improving photosystem II (PSII), and relevant gene expression. Spermidine significantly decreases the H2O2 and O2.- contents[1].

Acarbose is an alpha glucosidase inhibitor which decreases intestinal absorption of carbohydrates and is used as an adjunctive therapy in the management of type 2 diabetes. Acarbose has been linked to rare instances of clinically apparent acute liver injury. Acarbose is a natural product found in Streptomyces glaucescens, Streptomyces coelicoflavus, and other organisms with data available. Acarbose is a pseudotetrasaccharide and inhibitor of alpha-glucosidase and pancreatic alpha-amylase with antihyperglycemic activity. Acarbose binds to and inhibits alpha-glucosidase, an enteric enzyme found in the brush border of the small intestines that hydrolyzes oligosaccharides and disaccharides into glucose and other monosaccharides. This prevents the breakdown of larger carbohydrates into glucose and decreases the rise in postprandial blood glucose levels. In addition, acarbose inhibits pancreatic alpha-amylase which hydrolyzes complex starches to oligosaccharides in the small intestines.

Acetylcholine

Bournonville brand OF acetylcholine chloride

C7H16NO2+ (146.1181)

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).
