L-Carnitine

C7H15NO3 (161.105188)

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

Naringenin

C15H12O5 (272.0684702)

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

C10H14N2O5 (242.09026740000002)

Deoxythymidine, also known as 2-deoxy-5-methyluridine or 5-methyl-2-deoxyuridine, is a member of the class of compounds known as pyrimidine 2-deoxyribonucleosides. Pyrimidine 2-deoxyribonucleosides are compounds consisting of a pyrimidine linked to a ribose which lacks a hydroxyl group at position 2. Deoxythymidine is soluble (in water) and a very weakly acidic compound (based on its pKa). Deoxythymidine can be synthesized from thymine. Deoxythymidine is also a parent compound for other transformation products, including but not limited to, tritiated thymidine, alpha-tritiated thymidine, and 5,6-dihydrothymidine. Deoxythymidine can be found in a number of food items such as butternut squash, mammee apple, catjang pea, and climbing bean, which makes deoxythymidine a potential biomarker for the consumption of these food products. Deoxythymidine can be found primarily in most biofluids, including blood, amniotic fluid, cerebrospinal fluid (CSF), and urine, as well as throughout most human tissues. Deoxythymidine exists in all living species, ranging from bacteria to humans. In humans, deoxythymidine is involved in the pyrimidine metabolism. Deoxythymidine is also involved in few metabolic disorders, which include beta ureidopropionase deficiency, dihydropyrimidinase deficiency, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and UMP synthase deficiency (orotic aciduria). Moreover, deoxythymidine is found to be associated with canavan disease and degenerative disc disease. Thymidine (deoxythymidine; other names deoxyribosylthymine, thymine deoxyriboside) is a pyrimidine deoxynucleoside.

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

Adenosine

C10H13N5O4 (267.09674980000005)

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

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

It is relatively toxic parenterally, but has been used orally for various parasitic and fungal infections and as antidiarrheal. See also: Goldenseal (part of); Berberis aristata stem (part of). Berberine is a quaternary ammonium salt that belongs to the protoberberine group of benzylisoquinoline alkaloids. Chemically, berberine is classified as an isoquinoline alkaloid. More specifically, berberine is a plant alkaloid derived from tyrosine through a complex 8 step biosynthetic process. Berberine is found in plants such as Berberis vulgaris (barberry), Berberis aristata (tree turmeric), Mahonia aquifolium (Oregon grape) and Hydrastis canadensis (goldenseal). Two other known berberine-containing plants are Phellodendron chinense and Phellodendron amurense. Berberine is usually found in the roots, rhizomes, stems, and bark of Berberis plants. Due to berberines intense yellow color, plants that contain berberine were traditionally used to dye wool, leather, and wood. Under ultraviolet light, berberine shows a strong yellow fluorescence, making it useful in histology for staining heparin in mast cells. Berberine is a bioactive plant compound that has been frequently used in traditional medicine. Among the known physiological effects or bioactivities are: 1) Antimicrobial action against bacteria, fungi, protozoa, viruses, helminthes, and Chlamydia; 2) Antagonism against the effects of cholera and E coli heat-stable enterotoxin; 3) Inhibition of intestinal ion secretion and of smooth muscle contraction; 4) Reduction of inflammation and 5) Stimulation of bile secretion and bilirubin discharge (PMID:32335802). Berberine can inhibit bacterial growth in the gut, including Helicobacter pylori, protect the intestinal epithelial barrier from injury, and ameliorate liver injury. Currently, berberine is sold as an Over-the-Counter (OTC) drug for treating gastrointestinal infections in China (PMID:18442638). Berberine also inhibits the proliferation of various types of cancer cells and impedes invasion and metastasis (PMID:32335802). Recent evidence has also confirmed that berberine improves the efficacy and safety of both chemo and radiotherapies for cancer treatment (PMID:32335802). Berberine has also been shown to regulate glucose and lipid metabolism in vitro and in vivo (PMID:18442638). In fact, berberine is the main active component of an ancient Chinese herb Coptis chinensis French, which has been used to treat diabetes for thousands of years. As an anti-diabetic, berberine increases glucose uptake by muscle fibers independent of insulin levels. It triggers AMPK activation and increases glycolysis, leading to decreased insulin resistance and decreased oxygen respiration. The same mechanism leads to a reduction in gluconeogenesis in the liver. AMPK activation by berberine also leads to an antiatherosclerotic effect in mice. Berberines AMPK activation may also underlie berberines anti-obesity effects and favorable influence on weight loss (PMID:18442638). While its use as a medication is widely touted, it is important to remember that berberine inhibits CYP2D6 and CYP3A4 enzymes, both of which are involved in the metabolism of many endogenous substances and xenobiotics, including a number of prescription drugs.

Sucrose

C12H22O11 (342.11620619999997)

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

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

Tryptamine

C10H12N2 (160.1000432)

Tryptamine, also known as TrpN, is a catabolite of tryptophan converted by the gut microbiota. After absorption through the intestinal epithelium, tryptophan catabolites enter the bloodstream and are later excreted in the urine. Both Clostridium sp. and Ruminococcus sp. have been found to convert tryptophan into tryptamine (PMID: 30120222). Tryptamine is a monoamine compound that is a common precursor molecule to many hormones and neurotransmitters. Biosynthesis generally proceeds from the amino acid tryptophan, with tryptamine acting as a precursor for other compounds. Substitutions to the tryptamine molecule give rise to a group of compounds collectively known as tryptamines. The most well-known tryptamines are serotonin, an important neurotransmitter, and melatonin, a hormone involved in regulating the sleep-wake cycle. Tryptamine has been detected, but not quantified in, several different foods, such as onion-family vegetables, acerola, Japanese walnuts, custard apples, and green zucchinis. This could make tryptamine a potential biomarker for the consumption of these foods. Tryptamine is an aminoalkylindole consisting of indole having a 2-aminoethyl group at the 3-position.

Glycocholic acid

C26H43NO6 (465.30902180000004)

Glycocholic acid is an acyl glycine and a bile acid-glycine conjugate. It is a secondary bile acid produced by the action of enzymes existing in the microbial flora of the colonic environment. Bacteroides, Bifidobacterium, Clostridium and Lactobacillus are involved in bile acid metabolism and produce glycocholic acid (PMID: 6265737; 10629797). In hepatocytes, both primary and secondary bile acids undergo amino acid conjugation at the C-24 carboxylic acid on the side chain, and almost all bile acids in the bile duct therefore exist in a glycine conjugated form (PMID: 16949895). More specifically, glycocholic acid or cholylglycine, is a crystalline bile acid involved in the emulsification of fats. It occurs as a sodium salt in the bile of mammals. Its anion is called glycocholate. As the glycine conjugate of cholic acid, this compound acts as a detergent to solubilize fats for absorption and is itself absorbed (PubChem). Bile acids are steroid acids found predominantly in bile of mammals. The distinction between different bile acids is minute, depends only on presence or absence of hydroxyl groups on positions 3, 7, and 12. Bile acids are physiological detergents that facilitate excretion, absorption, and transport of fats and sterols in the intestine and liver. Bile acids are also steroidal amphipathic molecules derived from the catabolism of cholesterol. They modulate bile flow and lipid secretion, are essential for the absorption of dietary fats and vitamins, and have been implicated in the regulation of all the key enzymes involved in cholesterol homeostasis. Bile acids recirculate through the liver, bile ducts, small intestine and portal vein to form an enterohepatic circuit. They exist as anions at physiological pH and, consequently, require a carrier for transport across the membranes of the enterohepatic tissues. The unique detergent properties of bile acids are essential for the digestion and intestinal absorption of hydrophobic nutrients. Bile acids have potent toxic properties (e.g., membrane disruption) and there are a plethora of mechanisms to limit their accumulation in blood and tissues (PMID: 11316487, 16037564, 12576301, 11907135). Glycocholic acid is found to be associated with alpha-1-antitrypsin deficiency, which is an inborn error of metabolism. Glycocholic acid is a bile acid glycine conjugate having cholic acid as the bile acid component. It has a role as a human metabolite. It is functionally related to a cholic acid and a glycochenodeoxycholic acid. It is a conjugate acid of a glycocholate.

L-Tryptophan

C11H12N2O2 (204.0898732)

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

Cholic acid

C24H40O5 (408.28755900000004)

Cholic acid is a bile acid that is 5beta-cholan-24-oic acid bearing three alpha-hydroxy substituents at position 3, 7 and 12. It has a role as a human metabolite and a mouse metabolite. It is a bile acid, a C24-steroid, a 3alpha-hydroxy steroid, a 7alpha-hydroxy steroid, a 12alpha-hydroxy steroid and a trihydroxy-5beta-cholanic acid. It is a conjugate acid of a cholate. Cholic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Cholic acid is a Bile Acid. Cholic acid is a naturally occurring bile acid that is used to treat patients with genetic deficiencies in the synthesis of bile acids. When given in high doses, cholic acid replacement therapy has been linked to minor elevations in serum aminotransferase levels, but it has not been linked to instances of clinically apparent acute liver injury with jaundice. Cholic acid is a natural product found in Caenorhabditis elegans, Bufo bufo, and Homo sapiens with data available. Cholic acid is a major primary bile acid produced in the liver and usually conjugated with glycine or taurine. It facilitates fat absorption and cholesterol excretion. Bile acids are steroid acids found predominantly in bile of mammals. The distinction between different bile acids is minute, depends only on presence or absence of hydroxyl groups on positions 3, 7, and 12. Bile acids are physiological detergents that facilitate excretion, absorption, and transport of fats and sterols in the intestine and liver. Bile acids are also steroidal amphipathic molecules derived from the catabolism of cholesterol. They modulate bile flow and lipid secretion, are essential for the absorption of dietary fats and vitamins, and have been implicated in the regulation of all the key enzymes involved in cholesterol homeostasis. Bile acids recirculate through the liver, bile ducts, small intestine and portal vein to form an enterohepatic circuit. They exist as anions at physiological pH and, consequently, require a carrier for transport across the membranes of the enterohepatic tissues. The unique detergent properties of bile acids are essential for the digestion and intestinal absorption of hydrophobic nutrients. Bile acids have potent toxic properties (e.g., membrane disruption) and there are a plethora of mechanisms to limit their accumulation in blood and tissues. (A3407, A3408, A3409, A3410).

When present in sufficiently high levels, cholic acid can act as a hepatotoxin and a metabotoxin. A hepatotoxin causes damage to the liver or liver cells. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Among the primary bile acids, cholic acid is considered to be the least hepatotoxic while deoxycholic acid is the most hepatoxic (PMID: 1641875). The liver toxicity of bile acids appears to be due to their ability to peroxidate lipids and to lyse liver cells. Chronically high levels of cholic acid are associated with familial hypercholanemia. In hypercholanemia, bile acids, including cholic acid, are elevated in the blood. This disease causes liver damage, extensive itching, poor fat absorption, and can lead to rickets due to lack of calcium in bones. The deficiency of normal bile acids in the intestines results in a deficiency of vitamin K, which also adversely affects clotting of the blood. The bile acid ursodiol (ursodeoxycholic acid) can improve symptoms associated with familial hypercholanemia. Cholic acid. CAS Common Chemistry.

L-Tyrosine

C9H11NO3 (181.0738896)

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

Threonine is an essential amino acid in humans (provided by food), Threonine is an important residue of many proteins, such as tooth enamel, collagen, and elastin. An important amino acid for the nervous system, threonine also plays an important role in porphyrin and fat metabolism and prevents fat buildup in the liver. Useful with intestinal disorders and indigestion, threonine has also been used to alleviate anxiety and mild depression. (NCI04) Threonine is an essential amino acid in humans. It is abundant in human plasma, particularly in newborns. Severe deficiency of threonine causes neurological dysfunction and lameness in experimental animals. Threonine is an immunostimulant which promotes the growth of thymus gland. It also can probably promote cell immune defense function. This amino acid has been useful in the treatment of genetic spasticity disorders and multiple sclerosis at a dose of 1 gram daily. It is highly concentrated in meat products, cottage cheese and wheat germ. The threonine content of most of the infant formulas currently on the market is approximately 20\\\\\\% higher than the threonine concentration in human milk. Due to this high threonine content the plasma threonine concentrations are up to twice as high in premature infants fed these formulas than in infants fed human milk. The whey proteins which are used for infant formulas are sweet whey proteins. Sweet whey results from cheese production. Threonine catabolism in mammals appears to be due primarily (70-80\\\\\\%) to the activity of threonine dehydrogenase (EC 1.1.1.103) that oxidizes threonine to 2-amino-3-oxobutyrate, which forms glycine and acetyl CoA, whereas threonine dehydratase (EC 4.2.1.16) that catabolizes threonine into 2-oxobutyrate and ammonia, is significantly less active. Increasing the threonine plasma concentrations leads to accumulation of threonine and glycine in the brain. Such accumulation affects the neurotransmitter balance which may have consequences for the brain development during early postnatal life. Thus, excessive threonine intake during infant feeding should be avoided. (A3450). An essential amino acid occurring naturally in the L-form, which is the active form. It is found in eggs, milk, gelatin, and other proteins. See also: Amlisimod (monomer of) ... View More ... Threonine (Thr) or L-threonine is an alpha-amino acid.

It is classified as a polar, uncharged (at physiological pH), aliphatic amino acid. Threonine is sometimes considered as a branched chain amino acid. Threonine was actually the last of the 20 amino acids to be discovered (in 1938). It was named threonine because it was similar in structure to threonic acid, a four-carbon monosaccharide. Threonine is an essential amino acid in humans, meaning the body cannot synthesize it and that it must be obtained from the diet. Foods high in threonine include cottage cheese, poultry, fish, meat, lentils, black turtle bean and sesame seeds. Adult humans require about 20 mg/kg body weight/day. In plants and microorganisms, threonine is synthesized from aspartic acid via alpha-aspartyl-semialdehyde and homoserine. In proteins, the threonine residue is susceptible to numerous posttranslational modifications. The hydroxyl side-chain can undergo O-linked glycosylation and phosphorylation through the action of a threonine kinase. Threonine is abundant in human plasma, particularly in newborns.

In many animals it is converted to pyruvate via threonine dehydrogenase. An intermediate in this pathway can undergo thiolysis with CoA to produce acetyl-CoA and glycine. In humans the gene for threonine dehydrogenase is an inactive pseudogene, so threonine is converted to alpha-ketobutyrate. From wide variety of protein hydrolysates.

Stachyose

C24H42O21 (666.2218482000001)

Stachyose is a tetrasaccharide consisting of two D-galactose units, one D-glucose unit, and one D-fructose unit sequentially linked. Stachyose is a normal human metabolite present in human milk and is naturally found in many vegetables (e.g. green beans, soybeans and other beans) and plants. The glycosylation of serum transferrin from galactosemic patients with a deficiency of galactose-1-phosphate uridyl transferase (EC 2. 7.7 12) is abnormal but becomes normal after treatment with a galactose-free diet. Adhering to a galactose-free diet by strictly avoiding dairy products and known hidden sources of galactose does not completely normalize galactose-1-phosphate (gal-1-P) in erythrocytes from patients with galactosemia, since galactose released from stachyose may be absorbed and contribute to elevated gal-1-P values in erythrocytes of galactosemic patients (PMID:7671975, 9499382).

Rutin

C27H30O16 (610.153378)

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

Inosine

C10H12N4O5 (268.08076619999997)

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

Guanosine

C10H13N5O5 (283.09166480000005)

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

Guanine

C5H5N5O (151.049408)

Guanine is one of the five main nucleobases found in the nucleic acids DNA and RNA. Guanine is a derivative of purine, consisting of a fused pyrimidine-imidazole ring system with conjugated double bonds. Being unsaturated, the bicyclic molecule is planar. The guanine nucleoside is called guanosine. The first isolation of guanine was reported in 1844 from the excreta of sea birds, known as guano, which was used as a source of fertilizer. High affinity binding of guanine nucleotides and the ability to hydrolyze bound GTP to GDP are characteristics of an extended family of intracellular proteins. Guanine nucleotide-binding regulatory proteins may be involved in the activation of phospholipases C and A2 by hormones and other ligands. The binding of hormones to receptors that activate phospholipase C is decreased by guanine nucleotides and these hormones also stimulate a high-affinity GTPase activity in cell membranes. Effects of hormones on phospholipase C activity in cell-free preparations are dependent on the presence of guanine nucleotides. Hypoxanthine-guanine phosphoribosyltransferase (HPRT, EC 2.4.2.8) is a purine salvage enzyme that catalyses the conversion of hypoxanthine and guanine to their respective mononucleotides. Partial deficiency of this enzyme can result in the overproduction of uric acid leading to a severe form of gout, whilst a virtual absence of HPRT activity causes the Lesch-Nyhan syndrome, an inborn error of metabolism, which is characterised by hyperuricaemia, mental retardation, choreoathetosis and compulsive self-mutilation. Peroxynitrite induces DNA base damage predominantly at guanine (G) and 8-oxoguanine (8-oxoG) nucleobases via oxidation reactions. G and 8-oxoG are the most reactive bases toward Peroxynitrite and possibly the major contributors to peroxynitrite-derived genotoxic and mutagenic lesions. The neutral G radical, reacts with NO2 to yield 8-nitroguanine and 5-nitro-4-guanidinohydantoin (PMID: 16352449, 2435586, 2838362, 1487231). Guanine is a 2-aminopurine carrying a 6-oxo substituent. It has a role as a human metabolite, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a purine nucleobase, an oxopurine and a member of 2-aminopurines. It derives from a hydride of a 9H-purine. Guanine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Guanine is a natural product found in Fritillaria thunbergii, Isatis tinctoria, and other organisms with data available.

L-Leucine

C6H13NO2 (131.0946238)

Leucine (Leu) or L-leucine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (‚ÄìNH2) and carboxyl (‚ÄìCOOH) functional groups, along with a side chain (R group) specific to each amino acid. L-leucine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Leucine is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aliphatic amino acid. Leucine is essential in humans, meaning the body cannot synthesize it, and it must be obtained from the diet. Human dietary sources are foods that contain protein, such as meats, dairy products, soy products, beans and legumes. L-Leucine is a branched chain amino acid (BCAA). The BCAAs consist of leucine, valine and isoleucine (and occasionally threonine). BCAAs are essential amino acids whose carbon structure is marked by a branch point at the beta-carbon position. BCAAs are critical to human life and are particularly involved in stress, energy and muscle metabolism. BCAA supplementation as therapy, both oral and intravenous, in human health and disease holds great promise. BCAAs have different metabolic routes, with valine going solely to carbohydrates (glucogenic), leucine solely to fats (ketogenic) and isoleucine being both a glucogenic and a ketogenic amino acid. The different metabolism accounts for different requirements for these essential amino acids in humans: 12 mg/kg, 14 mg/kg and 16 mg/kg of valine, leucine and isoleucine respectively. The primary metabolic end products of leucine metabolism are acetyl-CoA and acetoacetate; consequently, it is one of the two exclusively ketogenic amino acids, with lysine being the other. Leucine is the most important ketogenic amino acid in humans. The vast majority of l-leucine metabolism is initially catalyzed by the branched-chain amino acid aminotransferase enzyme, producing alpha-ketoisocaproate (alpha-KIC). alpha-KIC is metabolized by the mitochondrial enzyme branched-chain alpha-ketoacid dehydrogenase, which converts it to isovaleryl-CoA. Isovaleryl-CoA is subsequently metabolized by the enzyme isovaleryl-CoA dehydrogenase and converted to beta-methylcrotonyl-CoA (MC-CoA), which is used in the synthesis of acetyl-CoA and other compounds. During biotin deficiency, HMB can be synthesized from MC-CoA via enoyl-CoA hydratase and an unknown thioesterase enzyme, which convert MC-CoA into HMB-CoA and HMB-CoA into HMB respectively. Leucine has the capacity to directly stimulate myofibrillar muscle protein synthesis (PMID 15051860). This effect of leucine arises results from its role as an activator of the mechanistic target of rapamycin (mTOR) (PMID 23551944) a serine-threonine protein kinase that regulates protein biosynthesis and cell growth. The activation of mTOR by leucine is mediated through Rag GTPases. Leucine, like other BCAAs, is associated with insulin resistance. In particular, higher levels of leucine are observed in the blood of diabetic mice, rats, and humans (PMID 25287287). BCAAs such as leucine have different deficiency symptoms. Valine deficiency is marked by neurological defects in the brain, while isoleucine deficiency is marked by muscle tremors. Persistently low leucine levels can result in decreased appetite, poor feeding, lethargy, poor growth, weight loss, skin rashes, hair loss, and desquamation. Many types of inborn errors of BCAA metabolism exist and these are marked by various abnormalities. The most common form is maple syrup urine disease, marked by a characteristic urinary odor. Other abnormalities are associated with a wide range of symptoms, such as mental retardation, ataxia, hypoglycemia, spinal muscle atrophy, rash, vomiting and excessive muscle movement. Most forms of BCAA metabolism errors are corrected by dietary res... L-leucine is the L-enantiomer of leucine. It has a role as a plant metabolite, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite, a human metabolite, an algal metabolite and a mouse metabolite. It is a pyruvate family amino acid, a proteinogenic amino acid, a leucine and a L-alpha-amino acid. It is a conjugate base of a L-leucinium. It is a conjugate acid of a L-leucinate. It is an enantiomer of a D-leucine. It is a tautomer of a L-leucine zwitterion. An essential branched-chain amino acid important for hemoglobin formation. L-Leucine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Leucine is one of nine essential amino acids in humans (provided by food), Leucine is important for protein synthesis and many metabolic functions. Leucine contributes to regulation of blood-sugar levels; growth and repair of muscle and bone tissue; growth hormone production; and wound healing. Leucine also prevents breakdown of muscle proteins after trauma or severe stress and may be beneficial for individuals with phenylketonuria. Leucine is available in many foods and deficiency is rare. (NCI04) Leucine (abbreviated as Leu or L)[2] is a branched-chain л±-amino acid with the chemical formulaHO2CCH(NH2)CH2CH(CH3)2. Leucine is classified as a hydrophobic amino acid due to its aliphatic isobutyl side chain. It is encoded by six codons (UUA, UUG, CUU, CUC, CUA, and CUG) and is a major component of the subunits in ferritin, astacin, and other buffer proteins.

Uridine

C9H12N2O6 (244.0695332)

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

L-Proline

C5H9NO2 (115.0633254)

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

Raffinose

C18H32O16 (504.1690272)

Raffinose is a complex carbohydrate. It is a trisaccharide composed of galactose, fructose, and glucose. It can be found in beans, cabbage, brussels sprouts, broccoli, asparagus, other vegetables, and whole grains. Raffinose is hydrolyzed to D-galactose and sucrose by D-galactosidase (D-GAL). D-GAL also hydrolyzes other D-galactosides such as stachyose, verbascose, and galactinol [1-O-(D-galactosyl)-myoinositol], if present. The enzyme does not cleave linked galactose, as in lactose. Raffinose is also known as melitose and may be thought of as galactose and sucrose connected via an alpha(1->6) glycosidic linkage.

Citric acid

C6H8O7 (192.0270018)

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

Epigallocatechin gallate

C22H18O11 (458.0849078)

Epigallocatechin gallate (EGCG) is the principal catechin in tea from Camellia sinensis, the most consumed beverage worldwide (after water). Depending on brew time and temperature, a single cup of green tea may contain 100-200 mg EGCG. To control the dose of EGCG administered in experimental studies, green tea solids (GTS) or capsules of green tea extract standardized to EGCG content are often employed. However, there is considerable variability in the EGCG content of commercially available dietary supplements, ranging from 12-143\\\\\\\\% of the tablet or capsule weight. While standardizing tea preparations to EGCG or using highly purified EGCG for research presents an important strategy for the conduct of precise studies as well as the ability to replicate experiments, it is worth noting this approach limits the potential contributions and possible synergy with other bioactive tea ingredients, including caffeine and other flavonoids. Human studies of the bioavailability of green tea catechins reveal these compounds to be poorly absorbed, with <0.1\\\\\\\\% of ingested catechins appearing in blood. Most ingested EGCG is rapidly cleared from blood with an elimination half-life of {approx}3 h and preferentially excreted via bile to the colon. The growing interest in the role of EGCG in health promotion and disease prevention is reflected by an exponential growth of research publications in this field.

Ferulic acid

C10H10O4 (194.057906)

trans-Ferulic acid is a highly abundant phenolic phytochemical which is present in plant cell walls. Ferulic acid is a phenolic acid that can be absorbed by the small intestine and excreted through the urine. It is one of the most abundant phenolic acids in plants, varying from 5 g/kg in wheat bran to 9 g/kg in sugar-beet pulp and 50 g/kg in corn kernel. It occurs primarily in seeds and leaves both in its free form (albeit rarely) and covalently linked to lignin and other biopolymers. It is usually found as ester cross-links with polysaccharides in the cell wall, such as arabinoxylans in grasses, pectin in spinach and sugar beet, and xyloglucans in bamboo. It also can cross-link with proteins. Due to its phenolic nucleus and an extended side chain conjugation (carbohydrates and proteins), it readily forms a resonance-stabilized phenoxy radical which accounts for its potent antioxidant potential. Food supplementation with curcumin and ferulic acid is considered a nutritional approach to reducing oxidative damage and amyloid pathology in Alzheimer disease (PMID:17127365, 1398220, 15453708, 9878519).

4-Hydroxybenzoic acid

C7H6O3 (138.03169259999999)

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

L-Phenylalanine

C9H11NO2 (165.0789746)

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

Phenylalanine is highly concentrated in high protein foods, such as meat, cottage cheese and wheat germ. A new dietary source of phenylalanine is artificial sweeteners containing aspartame. Aspartame appears to be nutritious except in hot beverages; however, it should be avoided by phenylketonurics and pregnant women. Phenylketonurics, who have a genetic error of phenylalanine metabolism, have elevated serum plasma levels of phenylalanine up to 400 times normal. Mild phenylketonuria can be an unsuspected cause of hyperactivity, learning problems, and other developmental problems in children. Phenylalanine can be an effective pain reliever. Its use in premenstrual syndrome and Parkinsons may enhance the effects of acupuncture and electric transcutaneous nerve stimulation (TENS). Phenylalanine and tyrosine, like L-dopa, produce a catecholamine effect. Phenylalanine is better absorbed than tyrosine and may cause fewer headaches. Low phenylalanine diets have been prescribed for certain cancers with mixed results. Some tumors use more phenylalanine (particularly melatonin-producing tumors called melanoma). One strategy is to exclude this amino acid from the diet, i.e., a Phenylketonuria (PKU) diet (compliance is a difficult issue; it is hard to quantify and is under-researched). The other strategy is just to increase phenylalanines competing amino acids, i.e., tryptophan, valine, isoleucine and leucine, but not tyrosine.

View More ... L-phenylalanine, also known as phe or f, belongs to phenylalanine and derivatives class of compounds. Those are compounds containing phenylalanine or a derivative thereof resulting from reaction of phenylalanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. L-phenylalanine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). L-phenylalanine can be found in watermelon, which makes L-phenylalanine a potential biomarker for the consumption of this food product. L-phenylalanine can be found primarily in most biofluids, including sweat, blood, urine, and cerebrospinal fluid (CSF), as well as throughout all human tissues. L-phenylalanine exists in all living species, ranging from bacteria to humans. In humans, L-phenylalanine is involved in a couple of metabolic pathways, which include phenylalanine and tyrosine metabolism and transcription/Translation. L-phenylalanine is also involved in few metabolic disorders, which include phenylketonuria, tyrosinemia type 2 (or richner-hanhart syndrome), and tyrosinemia type 3 (TYRO3). Moreover, L-phenylalanine is found to be associated with viral infection, dengue fever, hypothyroidism, and myocardial infarction. L-phenylalanine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Phenylalanine (Phe or F) is an α-amino acid with the formula C 9H 11NO 2. It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine. This essential amino acid is classified as neutral, and nonpolar because of the inert and hydrophobic nature of the benzyl side chain. The L-isomer is used to biochemically form proteins, coded for by DNA. The codons for L-phenylalanine are UUU and UUC. Phenylalanine is a precursor for tyrosine; the monoamine neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline); and the skin pigment melanin . Hepatic. L-phenylalanine that is not metabolized in the liver is distributed via the systemic circulation to the various tissues of the body, where it undergoes metabolic reactions similar to those that take place in the liver (DrugBank). If PKU is diagnosed early, an affected newborn can grow up with normal brain development, but only by managing and controlling phenylalanine levels through diet, or a combination of diet and medication. The diet requires severely restricting or eliminating foods high in phenylalanine, such as meat, chicken, fish, eggs, nuts, cheese, legumes, milk and other dairy products. Starchy foods, such as potatoes, bread, pasta, and corn, must be monitored. Optimal health ranges (or "target ranges") of serum phenylalanine are between 120 and 360 µmol/L, and aimed to be achieved during at least the first 10 years of life. Recently it has been found that a chiral isomer of L-phenylalanine (called D-phenylalanine) actually arrests the fibril formation by L-phenylalanine and gives rise to flakes. These flakes do not propagate further and prevent amyloid formation by L-phenylalanine. D-phenylalanine may qualify as a therapeutic molecule in phenylketonuria (A8161) (T3DB). L-Phenylalanine.

Hesperidin is an abundant and inexpensive by-product of Citrus cultivation and is the major flavonoid in sweet orange and lemon. In young immature oranges it can account for up to 14\\\\% of the fresh weight of the fruit due to vitamin C deficiency such as bruising due to capillary fragility were found in early studies to be relieved by crude vitamin C extract but not by purified vitamin C. The bioflavonoids, formerly called "vitamin P", were found to be the essential components in correcting this bruising tendency and improving the permeability and integrity of the capillary lining. These bioflavonoids include hesperidin, citrin, rutin, flavones, flavonols, catechin and quercetin. Of historical importance is the observation that "citrin", a mixture of two flavonoids, eriodictyol and hesperidin, was considered to possess a vitamin-like activity, as early as in 1949. Hesperidin deficiency has since been linked with abnormal capillary leakiness as well as pain in the extremities causing aches, weakness and night leg cramps. Supplemental hesperidin also helps in reducing oedema or excess swelling in the legs due to fluid accumulation. As with other bioflavonoids, hesperidin works best when administered concomitantly with vitamin C. No signs of toxicity have been observed with normal intake of hesperidin. Hesperidin was first discovered in 1827, by Lebreton, but not in a pure state and has been under continuous investigation since then (PMID:11746857).

Succinic acid

C4H6O4 (118.0266076)

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

Palmitic acid

C16H32O2 (256.2402172)

Palmitic acid, also known as palmitate or hexadecanoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, palmitic acid is considered to be a fatty acid lipid molecule. Palmitic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Palmitic acid can be found in a number of food items such as sacred lotus, spinach, shallot, and corn salad, which makes palmitic acid a potential biomarker for the consumption of these food products. Palmitic acid can be found primarily in most biofluids, including feces, sweat, cerebrospinal fluid (CSF), and urine, as well as throughout most human tissues. Palmitic acid exists in all living species, ranging from bacteria to humans. In humans, palmitic acid is involved in several metabolic pathways, some of which include alendronate action pathway, rosuvastatin action pathway, simvastatin action pathway, and cerivastatin action pathway. Palmitic acid is also involved in several metabolic disorders, some of which include hypercholesterolemia, familial lipoprotein lipase deficiency, ethylmalonic encephalopathy, and carnitine palmitoyl transferase deficiency (I). Moreover, palmitic acid is found to be associated with schizophrenia. Palmitic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Palmitic acid, or hexadecanoic acid in IUPAC nomenclature, is the most common saturated fatty acid found in animals, plants and microorganisms. Its chemical formula is CH3(CH2)14COOH, and its C:D is 16:0. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Palmitic acid can also be found in meats, cheeses, butter, and dairy products. Palmitate is the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at physiologic pH (7.4) . Palmitic acid is the first fatty acid produced during lipogenesis (fatty acid synthesis) and from which longer fatty acids can be produced. Palmitate negatively feeds back on acetyl-CoA carboxylase (ACC) which is responsible for converting acetyl-ACP to malonyl-ACP on the growing acyl chain, thus preventing further palmitate generation (DrugBank). Palmitic acid, or hexadecanoic acid, is one of the most common saturated fatty acids found in animals, plants, and microorganisms. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Excess carbohydrates in the body are converted to palmitic acid. Palmitic acid is the first fatty acid produced during fatty acid synthesis and is the precursor to longer fatty acids. As a consequence, palmitic acid is a major body component of animals. In humans, one analysis found it to make up 21–30\\\% (molar) of human depot fat (PMID: 13756126), and it is a major, but highly variable, lipid component of human breast milk (PMID: 352132). Palmitic acid is used to produce soaps, cosmetics, and industrial mould release agents. These applications use sodium palmitate, which is commonly obtained by saponification of palm oil. To this end, palm oil, rendered from palm tree (species Elaeis guineensis), is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate. Aluminium salts of palmitic acid and naphthenic acid were combined during World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and palmitic acid (Wikipedia). Palmitic acid is also used in the determination of water hardness and is a surfactant of Levovist, an intravenous ultrasonic contrast agent. Hexadecanoic acid is a straight-chain, sixteen-carbon, saturated long-chain fatty acid. It has a role as an EC 1.1.1.189 (prostaglandin-E2 9-reductase) inhibitor, a plant metabolite, a Daphnia magna metabolite and an algal metabolite.

Dicumarol

C19H12O6 (336.06338519999997)

Dicoumarol is a hydroxycoumarin that is methane in which two hydrogens have each been substituted by a 4-hydroxycoumarin-3-yl group. Related to warfarin, it has been used as an anticoagulant. It has a role as a vitamin K antagonist, an anticoagulant, an EC 1.6.5.2 [NAD(P)H dehydrogenase (quinone)] inhibitor and a Hsp90 inhibitor. Dicoumarol is an oral anticoagulant agent that works by interfering with the metabolism of vitamin K. In addition to its clinical use, it is also used in biochemical experiments as an inhibitor of reductases. Dicumarol is a natural product found in Homo sapiens and Viola arvensis with data available. Dicumarol is a hydroxycoumarin originally isolated from molding sweet-clover hay, with anticoagulant and vitamin K depletion activities. Dicumarol is a competitive inhibitor of vitamin K epoxide reductase; thus, it inhibits vitamin K recycling and causes depletion of active vitamin K in blood. This prevents the formation of the active form of prothrombin and several other coagulant enzymes, and inhibits blood clotting. Dicumarol is only found in individuals that have used or taken this drug. It is an oral anticoagulant that interferes with the metabolism of vitamin K. It is also used in biochemical experiments as an inhibitor of reductases. [PubChem] Dicumarol inhibits vitamin K reductase, resulting in depletion of the reduced form of vitamin K (vitamin KH2). As vitamin K is a cofactor for the carboxylation of glutamate residues on the N-terminal regions of vitamin K-dependent proteins, this limits the gamma-carboxylation and subsequent activation of the vitamin K-dependent coagulant proteins. The synthesis of vitamin K-dependent coagulation factors II, VII, IX, and X and anticoagulant proteins C and S is inhibited. Depression of three of the four vitamin K-dependent coagulation factors (factors II, VII, and X) results in decresed prothrombin levels and a decrease in the amount of thrombin generated and bound to fibrin. This reduces the thrombogenicity of clots. An oral anticoagulant that interferes with the metabolism of vitamin K. It is also used in biochemical experiments as an inhibitor of reductases.

Trehalose

C12H22O11 (342.11620619999997)

Trehalose, also known as mycose, is a 1-alpha (disaccharide) sugar found extensively but not abundantly in nature. It is thought to be implicated in anhydrobiosis - the ability of plants and animals to withstand prolonged periods of desiccation. The sugar is thought to form a gel phase as cells dehydrate, which prevents disruption of internal cell organelles by effectively splinting them in position. Rehydration then allows normal cellular activity to be resumed without the major, generally lethal damage that would normally follow a dehydration/reyhdration cycle. Trehalose is a non-reducing sugar formed from two glucose units joined by a 1-1 alpha bond giving it the name of alpha-D-glucopyranoglucopyranosyl-1,1-alpha-D-glucopyranoside. The bonding makes trehalose very resistant to acid hydrolysis, and therefore stable in solution at high temperatures even under acidic conditions. The bonding also keeps non-reducing sugars in closed-ring form, such that the aldehyde or ketone end-groups do not bind to the lysine or arginine residues of proteins (a process called glycation). The enzyme trehalase, present but not abundant in most people, breaks it into two glucose molecules, which can then be readily absorbed in the gut. Trehalose is an important components of insects circulating fluid. It acts as a storage form of insect circulating fluid and it is important in respiration. Trehalose has also been found to be a metabolite of Burkholderia, Escherichia and Propionibacterium (PMID:12105274; PMID:25479689) (krishikosh.egranth.ac.in/bitstream/1/84382/1/88571\\\\%20P-1257.pdf). Alpha,alpha-trehalose is a trehalose in which both glucose residues have alpha-configuration at the anomeric carbon.

4-Pyridoxic acid

C8H9NO4 (183.0531554)

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

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

Creatinine

C4H7N3O (113.0589092)

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

The typical reference range for women is considered about 45-90 µmol/L; for men 60-110 µmol/L. Creatine and creatinine are metabolized in the kidneys, muscle, liver, and pancreas. Creatinine.

2-Aminobenzoic acid, also known as anthranilic acid or O-aminobenzoate, belongs to the class of organic compounds known as aminobenzoic acids. These are benzoic acids containing an amine group attached to the benzene moiety. Within humans, 2-aminobenzoic acid participates in a number of enzymatic reactions. In particular, 2-aminobenzoic acid and formic acid can be biosynthesized from formylanthranilic acid through its interaction with the enzyme kynurenine formamidase. In addition, 2-aminobenzoic acid and L-alanine can be biosynthesized from L-kynurenine through its interaction with the enzyme kynureninase. It is a substrate of enzyme 2-Aminobenzoic acid hydroxylase in benzoate degradation via hydroxylation pathway (KEGG). In humans, 2-aminobenzoic acid is involved in tryptophan metabolism. Outside of the human body, 2-Aminobenzoic acid has been detected, but not quantified in several different foods, such as mamey sapotes, prairie turnips, rowals, natal plums, and hyacinth beans. This could make 2-aminobenzoic acid a potential biomarker for the consumption of these foods. 2-Aminobenzoic acid is a is a tryptophan-derived uremic toxin with multidirectional properties that can affect the hemostatic system. Uremic syndrome may affect any part of the body and can cause nausea, vomiting, loss of appetite, and weight loss.

Deoxycytidine

C9H13N3O4 (227.0906018)

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

Deoxyadenosine

C10H13N5O3 (251.10183480000003)

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

Tryptophol

C10H11NO (161.0840596)

Tryptophol, also known as indole-3-ethanol, is an indolyl alcohol that is ethanol substituted by a 1H-indol-3-yl group at position 2. It has a role as a Saccharomyces cerevisiae metabolite, an auxin and a plant metabolite. Tryptophol is a catabolite of tryptophan converted by the gut microbiota. After absorption through the intestinal epithelium, tryptophan catabolites enter the bloodstream and are later excreted in the urine (PMID:30120222). Tryptophol production was negatively associated with interferon-gamma production (IFNγ) which suggests that tryptophol has anti-inflammatory properties (PMID:27814509). Tryptophol has also been identified as the hypnotic agent in trypanosomal sleeping sickness, and because it is formed in vivo after ethanol or disulfiram treatment, it is also associated with the study of alcoholism (PMID:7241135). Indole-3-ethanol is a dietary indole present in cruciferous vegetables that has been shown to influence estradiol metabolism in humans and may provide a new chemopreventive approach to estrogen-dependent diseases.

Dehydroepiandrosterone

C19H28O2 (288.2089188)

Dehydroepiandrosterone (DHEA) is a natural steroid hormone produced from cholesterol by the adrenal glands. DHEA is also produced in the gonads, adipose tissue and the brain. DHEA is structurally similar to, and is a precursor of, androstenedione, testosterone, estradiol, estrone and estrogen. It is the most abundant hormone in the human body. Most of DHEA is sulfated (dehydroepiandrosterone sulfate- DEHAS) before secretion. DHEAS is the sulfated version of DHEA; - this conversion is reversibly catalyzed by sulfotransferase (SULT2A1) primarily in the adrenals, the liver, and small intestines. In blood, most DHEA is found as DHEAS with levels that are about 300 times higher than free DHEA. Blood measurements of DHEAS/DHEA are useful to detect excess adrenal activity as seen in adrenal cancer or hyperplasia, including certain forms of congenital adrenal hyperplasia. Women with polycystic ovary syndrome tend to have normal or mildly elevated levels of DHEAS. [HMDB]. Dehydroepiandrosterone is found in many foods, some of which are summer grape, quinoa, calabash, and chinese chives.

C19H26O2 (286.1932696)

Androst-4-en-3,17-dione, also known as androstenedione or delta(4)-androsten-3,17-dione, belongs to androgens and derivatives class of compounds. Those are 3-hydroxylated C19 steroid hormones. They are known to favor the development of masculine characteristics. They also show profound effects on scalp and body hair in humans. Thus, androst-4-en-3,17-dione is considered to be a steroid lipid molecule. Androst-4-en-3,17-dione is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Androst-4-en-3,17-dione can be found in a number of food items such as naranjilla, purslane, common cabbage, and oval-leaf huckleberry, which makes androst-4-en-3,17-dione a potential biomarker for the consumption of these food products.

In humans, androst-4-en-3,17-dione is involved in a couple of metabolic pathways, which include androgen and estrogen metabolism and androstenedione metabolism. Androst-4-en-3,17-dione is also involved in a couple of metabolic disorders, which include 17-beta hydroxysteroid dehydrogenase III deficiency and aromatase deficiency. Moreover, androst-4-en-3,17-dione is found to be associated with rheumatoid arthritis, thyroid cancer , cushings Syndrome, and schizophrenia. Androst-4-en-3,17-dione is a non-carcinogenic (not listed by IARC) potentially toxic compound. Androstenedione is a delta-4 19-carbon steroid that is produced not only in the testis, but also in the ovary and the adrenal cortex. Depending on the tissue type, androstenedione can serve as a precursor to testosterone as well as estrone and estradiol. It is the common precursor of male and female sex hormones. Some androstenedione is also secreted into the plasma and may be converted in peripheral tissues to testosterone and estrogens. Androstenedione originates either from the conversion of dehydroepiandrosterone or from 17-hydroxyprogesterone. It is further converted to either testosterone or estrone. The production of adrenal androstenedione is governed by ACTH, while the production of gonadal androstenedione is under control by gonadotropins.

Tetrahydrobiopterin

C9H15N5O3 (241.11748400000002)

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.

Adenosine monophosphate

C10H14N5O7P (347.06308240000004)

Adenosine monophosphate, also known as adenylic acid or amp, is a member of the class of compounds known as purine ribonucleoside monophosphates. Purine ribonucleoside monophosphates are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. Adenosine monophosphate is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Adenosine monophosphate can be found in a number of food items such as kiwi, taro, alaska wild rhubarb, and skunk currant, which makes adenosine monophosphate a potential biomarker for the consumption of these food products. Adenosine monophosphate can be found primarily in most biofluids, including blood, feces, cerebrospinal fluid (CSF), and urine, as well as throughout all human tissues. Adenosine monophosphate exists in all living species, ranging from bacteria to humans. In humans, adenosine monophosphate is involved in several metabolic pathways, some of which include josamycin action pathway, methacycline action pathway, nevirapine action pathway, and aspartate metabolism. Adenosine monophosphate is also involved in several metabolic disorders, some of which include hyperornithinemia-hyperammonemia-homocitrullinuria [hhh-syndrome], molybdenum cofactor deficiency, xanthinuria type I, and mitochondrial DNA depletion syndrome. Adenosine monophosphate is a drug which is used for nutritional supplementation, also for treating dietary shortage or imbalanc. Adenosine monophosphate, also known as 5-adenylic acid and abbreviated AMP, is a nucleotide that is found in RNA. It is an ester of phosphoric acid with the nucleoside adenosine. AMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase adenine. AMP can be produced during ATP synthesis by the enzyme adenylate kinase. AMP has recently been approved as a Bitter Blocker additive to foodstuffs. When AMP is added to bitter foods or foods with a bitter aftertaste it makes them seem sweeter. This potentially makes lower calorie food products more palatable.

5'-Methylthioadenosine

C11H15N5O3S (297.089556)

5-Methylthioadenosine, also known as MTA or thiomethyladenosine, belongs to the class of organic compounds known as 5-deoxy-5-thionucleosides. These are 5-deoxyribonucleosides in which the ribose is thio-substituted at the 5position by a S-alkyl group. 5-Methylthioadenosine is metabolized solely by MTA-phosphorylase, to yield 5-methylthioribose-1-phosphate and adenine, a crucial step in the methionine and purine salvage pathways, respectively. 5-Methylthioadenosine exists in all living species, ranging from bacteria to humans. 5-Methylthioadenosine (MTA) is a naturally occurring sulfur-containing nucleoside present in all mammalian tissues. Within humans, 5-methylthioadenosine participates in a number of enzymatic reactions. In particular, 5-methylthioadenosine and spermidine can be biosynthesized from S-adenosylmethioninamine and putrescine through the action of the enzyme spermidine synthase. In addition, 5-methylthioadenosine can be converted into 5-methylthioribose 1-phosphate and L-methionine; which is catalyzed by the enzyme S-methyl-5-thioadenosine phosphorylase. It is produced from S-adenosylmethionine mainly through the polyamine biosynthetic pathway, where it behaves as a powerful inhibitory product. For instance, 5-Methylthioadenosine has been shown to influence the regulation of gene expression, proliferation, differentiation, and apoptosis (PMID:15313459). In humans, 5-methylthioadenosine is involved in the metabolic disorder called hypermethioninemia. Outside of the human body, 5-Methylthioadenosine has been detected, but not quantified in several different foods, such as soursops, allspices, summer grapes, alaska wild rhubarbs, and breadfruits. Elevated excretion appears in children with severe combined immunodeficiency syndrome (SCID) (PMID:3987052). Evidence suggests that 5-Methylthioadenosine can affect cellular processes in many ways. 5-Methylthioadenosine can be found in human urine. 5-deoxy-5-methylthioadenosine, also known as S-methyl-5-thioadenosine or mta, is a member of the class of compounds known as 5-deoxy-5-thionucleosides. 5-deoxy-5-thionucleosides are 5-deoxyribonucleosides in which the ribose is thio-substituted at the 5position by a S-alkyl group. 5-deoxy-5-methylthioadenosine is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 5-deoxy-5-methylthioadenosine can be found in a number of food items such as allspice, sesame, roselle, and bayberry, which makes 5-deoxy-5-methylthioadenosine a potential biomarker for the consumption of these food products. 5-deoxy-5-methylthioadenosine can be found primarily in blood and urine, as well as in human fibroblasts, platelet and prostate tissues. 5-deoxy-5-methylthioadenosine exists in all living species, ranging from bacteria to humans. In humans, 5-deoxy-5-methylthioadenosine is involved in a couple of metabolic pathways, which include methionine metabolism and spermidine and spermine biosynthesis. 5-deoxy-5-methylthioadenosine is also involved in several metabolic disorders, some of which include glycine n-methyltransferase deficiency, methionine adenosyltransferase deficiency, homocystinuria-megaloblastic anemia due to defect in cobalamin metabolism, cblg complementation type, and hypermethioninemia. 5'-Methylthioadenosine (5'-(Methylthio)-5'-deoxyadenosine) is a nucleoside generated from S-adenosylmethionine (SAM) during polyamine synthesis[1]. 5'-Methylthioadenosine suppresses tumors by inhibiting tumor cell proliferation, invasion, and the induction of apoptosis while controlling the inflammatory micro-environments of tumor tissue. 5'-Methylthioadenosine and its associated materials have striking regulatory effects on tumorigenesis[2]. 5'-Methylthioadenosine (5'-(Methylthio)-5'-deoxyadenosine) is a nucleoside generated from S-adenosylmethionine (SAM) during polyamine synthesis[1]. 5'-Methylthioadenosine suppresses tumors by inhibiting tumor cell proliferation, invasion, and the induction of apoptosis while controlling the inflammatory micro-environments of tumor tissue. 5'-Methylthioadenosine and its associated materials have striking regulatory effects on tumorigenesis[2]. 5'-Methylthioadenosine (5'-(Methylthio)-5'-deoxyadenosine) is a nucleoside generated from S-adenosylmethionine (SAM) during polyamine synthesis[1]. 5'-Methylthioadenosine suppresses tumors by inhibiting tumor cell proliferation, invasion, and the induction of apoptosis while controlling the inflammatory micro-environments of tumor tissue. 5'-Methylthioadenosine and its associated materials have striking regulatory effects on tumorigenesis[2].

5-Methyltetrahydrofolic acid

C20H25N7O6 (459.186623)

5 methyltetrahydrofolic acid (5-MTHF) is the most biologically active form of the B-vitamin known as folic acid, also known generically as folate. 5-MTHF functions, in concert with vitamin B12, as a methyl-group donor involved in the conversion of the amino acid homocysteine to methionine. Methyl (CH3) group donation is vital to many bodily processes, including serotonin, melatonin, and DNA synthesis. Therapeutically, 5-MTHF is instrumental in reducing homocysteine levels, preventing neural tube defects, and improving vascular endothelial function. Research on folate supplementation suggests it plays a key role in preventing cervical dysplasia and protecting against neoplasia in ulcerative colitis. Folic acid also shows promise as part of a nutritional protocol to treat vitiligo, and may reduce inflammation of the gingiva. Furthermore, certain neurological, cognitive, and psychiatric presentations may be secondary to folate deficiency. Such presentations include depression, peripheral neuropathy, myelopathy, restless legs syndrome, insomnia, dementia, forgetfulness, irritability, endogenous depression, organic psychosis, and schizophrenia-like syndromes. After ingestion, the process of conversion of folic acid to the metabolically active coenzyme forms is relatively complex. Synthesis of the active forms of folic acid requires several enzymes, adequate liver and intestinal function, and adequate supplies of riboflavin (B2), niacin (B3), pyridoxine (B6), zinc, vitamin C, and serine. After formation of the coenzyme forms of the vitamin in the liver, these metabolically active compounds are secreted into the small intestine with bile (the folate enterohepatic cycle), where they are reabsorbed and distributed to tissues throughout the body. Human pharmacokinetic studies indicate folic acid has high bioavailability, with large oral doses of folic acid substantially raising plasma levels in healthy subjects in a time and dose dependent manner. Red blood cells (RBCs) appear to be the storage depot for folic acid, as RBC levels remain elevated for periods in excess of 40 days following discontinuation of supplementation. Folic acid is poorly transported to the brain and rapidly cleared from the central nervous system. The primary methods of elimination of absorbed folic acid are fecal (through bile) and urinary. Despite the biochemical complexity of this process, evidence suggests oral supplementation with folic acid increases the bodys pool of 5-MTHF in healthy individuals. However, enzyme defects, mal-absorption, digestive system pathology, and liver disease can result in impaired ability to activate folic acid. In fact, some individuals have a severe congenital deficiency of the enzyme Methyl tetrahydrofolate reductase (5-MTHFR), which is needed to convert folic acid to 5-MTHF. Milder forms of this enzyme defect likely interact with dietary folate status to determine risk for some disease conditions. In individuals with a genetic defect of this enzyme (whether mild or severe), supplementation with 5- MTHF might be preferable to folic acid supplementation.

Acetyl-N-formyl-5-methoxykynurenamine

C13H16N2O4 (264.1110016)

Acetyl-N-formyl-5-methoxykynurenamine (AFMK) results from the oxidative cleavage of the pyrrole ring during melatonin oxidation by myeloperoxidase (MPO), a superoxide anion (O)-dependent reaction. AFMK is also expected to be formed from oxidation catalyzed by the unspecific enzyme indoleamine-2,3-dioxygenase (IDO), found in a variety of cell types including monocyte/macrophage lineages. MPO- and IDO-catalyzed melatonin oxidation has the requirement of O in common, a species formed in large amounts in inflammatory conditions. The non-enzymatic formation of AFMK can also be expected by its direct reaction with highly reactive oxygen species, such as hydroxyl radical and singlet oxygen. Thus, we assume that AFMK is a product formed in a route of melatonin metabolism, especially active in inflammation. As AFMK is biologically more active on leukocytes than melatonin, the metabolizing of melatonin to AFMK at inflammatory sites possibly plays a role in immunomodulation. AFMK is found in the CSF of patients with meningitis, and in some samples at a remarkably high concentration, with AFMK found in some patients exceeding the concentration of melatonin normally found in serum.

Oxoglutaric acid

C5H6O5 (146.0215226)

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

Argininosuccinic acid

C10H18N4O6 (290.12262880000003)

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

L-Asparagine

C4H8N2O3 (132.05348980000002)

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

Pseudouridine

C9H12N2O6 (244.0695332)

Beta-pseudouridine, also known as p or 5-(b-D-ribofuranosyl)uracil, is a member of the class of compounds known as nucleoside and nucleotide analogues. Nucleoside and nucleotide analogues are analogues of nucleosides and nucleotides. These include phosphonated nucleosides, C-glycosylated nucleoside bases, analogues where the sugar unit is a pyranose, and carbocyclic nucleosides, among others. Beta-pseudouridine is soluble (in water) and a very weakly acidic compound (based on its pKa). Beta-pseudouridine can be found in a number of food items such as eggplant, wax gourd, asparagus, and garden cress, which makes beta-pseudouridine a potential biomarker for the consumption of these food products. Beta-pseudouridine can be found primarily in amniotic fluid, blood, feces, and urine. Beta-pseudouridine exists in all living species, ranging from bacteria to humans. Moreover, beta-pseudouridine is found to be associated with canavan disease.

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

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

Sphinganine

C18H39NO2 (301.2980634)

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

Metanephrine

C10H15NO3 (197.105188)

Metanephrine is a metabolite of epinephrine created by action of catechol O-methyltransferase on epinephrine. Technically it is a product of epinephrine O-methylation. It is a commonly occurring, pharmacologically and physiologically inactive metabolite of epinephrine. The measurement of plasma free metanephrines is considered to be the best tool in the diagnosis of pheochromocytoma, a rare kind of adrenal medullary neoplasm. In adrenal chromaffin cells, leakage of norepinephrine and epinephrine from storage granules leads to substantial intracellular production of the O-methylated metabolite metanephrine. In fact, the adrenals constitute the single largest source out of any organ system including the liver for circulating metanephrine. In humans, about 93 percent of circulating metanephrine is derived from catecholamines metabolized within adrenal chromaffin cells. (PMID 15317907).

Hypoxanthine

C5H4N4O (136.03850939999998)

Hypoxanthine, also known as purine-6-ol or Hyp, belongs to the class of organic compounds known as purines. Purines are a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. Hypoxanthine is also classified as an oxopurine, Hypoxanthine is a naturally occurring purine derivative and a reaction intermediate in the metabolism of adenosine and in the formation of nucleic acids by the nucleotide salvage pathway. Hypoxanthine exists in all living species, ranging from bacteria to plants to humans. Hypoxanthine has been detected, but not quantified in, several different foods, such as radish (var.), mountain yams, welsh onions, greenthread tea, and common beets. Hypoxanthine is occasionally found as a constituent of nucleic acids, where it is present in the anticodon of tRNA in the form of its nucleoside inosine. Biologically, hypoxanthine can be formed a number of ways. For instance, it is one of the products of the action of xanthine oxidase on xanthine. However, more frequently xanthine is formed from oxidation of hypoxanthine by xanthine oxidoreductase. The enzyme hypoxanthine-guanine phosphoribosyltransferase converts hypoxanthine into IMP in the nucleotide salvage pathway. Hypoxanthine is also a spontaneous deamination product of adenine. Under normal circumstances hypoxanthine is readily converted to uric acid. In this process, hypoxanthine is first oxidized to xanthine, which is further oxidized to uric acid by xanthine oxidase. Molecular oxygen, the oxidant in both reactions, is reduced to H2O2 and other reactive oxygen species. In humans, uric acid is the final product of purine degradation and is excreted in the urine. Within humans, hypoxanthine participates in a number of other enzymatic reactions. In particular, hypoxanthine and ribose 1-phosphate can be biosynthesized from inosine through its interaction with the enzyme purine nucleoside phosphorylase. Hypoxanthine is also involved in the metabolic disorder called the purine nucleoside phosphorylase deficiency. Purine nucleoside phosphorylase (PNP) deficiency is a disorder of the immune system (primary immunodeficiency) characterized by recurrent infections, neurologic symptoms, and autoimmune disorders. PNP deficiency causes a shortage of white blood cells, called T-cells, that help fight infection. Affected individuals develop neurologic symptoms, such as stiff or rigid muscles (spasticity), uncoordinated movements (ataxia), developmental delay, and intellectual disability. PNP deficiency is associated with an increased risk to develop autoimmune disorders, such as autoimmune hemolytic anemia, idiopathic thrombocytopenic purpura (ITP), autoimmune neutropenia, thyroiditis, and lupus. [Spectral] Hypoxanthine (exact mass = 136.03851) and Adenine (exact mass = 135.0545) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX. Additionally some of the peaks in this data contains dimers and other unidentified ions. Occurs widely in plant and animal tissue (CCD).

Indoleacetic acid

C10H9NO2 (175.0633254)

Indoleacetic acid (IAA) is a breakdown product of tryptophan metabolism and is often produced by the action of bacteria in the mammalian gut. Higher levels of IAA are associated with bacteria from Clostridium species including C. stricklandii, C. lituseburense, C. subterminale, and C. putrefaciens (PMID: 12173102). IAA can be found in Agrobacterium, Azospirillum, Bacillus, Bradyrhizobium, Clostridium, Enterobacter, Pantoea, Pseudomonas, Rhizobium (PMID: 12173102, PMID: 17555270, PMID: 12147474, PMID: 19400643, PMID: 9450337, PMID: 21397014) (https://link.springer.com/chapter/10.1007/978-1-4612-3084-7_7) (https://escholarship.org/uc/item/1bf1b5m3). Some endogenous production of IAA in mammalian tissues also occurs. It may be produced by the decarboxylation of tryptamine or the oxidative deamination of tryptophan. IAA frequently occurs at low levels in urine and has been found in elevated levels in the urine of patients with phenylketonuria (PMID: 13610897). IAA has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Using material extracted from human urine, it was discovered by Kogl in 1933 that indoleacetic acid is also an important plant hormone (PMID: 13610897). Specifically, IAA is a member of the group of phytohormones called auxins. IAA is generally considered to be the most important native auxin. Plant cells synthesize IAA from tryptophan (Wikipedia). IAA and some derivatives can be oxidized by horseradish peroxidase (HRP) into cytotoxic species. IAA is only toxic after oxidative decarboxylation; the effect of IAA/HRP is thought to be due in part to the formation of methylene-oxindole, which may conjugate with DNA bases and protein thiols. IAA/HRP could be used as the basis for targeted cancer, a potential new role for plant auxins in cancer therapy (PMID: 11163327). 1h-indol-3-ylacetic acid, also known as (indol-3-yl)acetate or heteroauxin, belongs to indole-3-acetic acid derivatives class of compounds. Those are compounds containing an acetic acid (or a derivative) linked to the C3 carbon atom of an indole. 1h-indol-3-ylacetic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 1h-indol-3-ylacetic acid is a mild, odorless, and sour tasting compound and can be found in a number of food items such as sweet bay, chinese bayberry, winter squash, and linden, which makes 1h-indol-3-ylacetic acid a potential biomarker for the consumption of these food products. 1h-indol-3-ylacetic acid can be found primarily in most biofluids, including blood, feces, saliva, and urine, as well as throughout most human tissues. 1h-indol-3-ylacetic acid exists in all living species, ranging from bacteria to humans. In humans, 1h-indol-3-ylacetic acid is involved in the tryptophan metabolism. Moreover, 1h-indol-3-ylacetic acid is found to be associated with appendicitis and irritable bowel syndrome. 1h-indol-3-ylacetic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound.

3-Sulfinoalanine

C3H7NO4S (153.0095782)

3-Sulfinoalanine or cysteinesulfinic acid is a N-methyl-D-aspartate agonist. It is a product of cysteine dioxygenase or CDO [EC 1.13.11.20]. In humans cysteine catabolism is tightly regulated via regulation of cysteine dioxygenase (CDO) levels in the liver, with the turnover of CDO protein being dramatically decreased when intracellular cysteine levels increase. This occurs in response to changes in the intracellular cysteine concentration via changes in the rate of CDO ubiquitination and degradation. Expressed at high levels in the liver with lower levels in the kidney, brain, and lung, cysteine dioxygenase catalyzes the addition of molecular oxygen to the sulfhydryl group of cysteine, yielding cysteinesulfinic acid. The oxidative catabolism of cysteine to cysteinesulfinate by CDO represents an irreversible loss of cysteine from the free amino acid pool. Once generated, cysteinesulfinate is shuttled into several pathways including hypotaurine/taurine synthesis, sulfite/sulfate production, and the generation of pyruvate.

L-Lysine

C6H14N2O2 (146.1055224)

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

Indole-3-methyl acetate

C11H11NO2 (189.0789746)

Indole-3-methyl acetate, also known as methyl indole-3-acetate (methyl-IAA), is a catabolite of tryptophan converted by the gut microbiota. After absorption through the intestinal epithelium, tryptophan catabolites enter the bloodstream and are later excreted in the urine (PMID: 30120222). Pediatric enthesitis-related arthritis (ERA) patients (i.e. spondyloarthropathy associated with inflammatory bowel disease) have intestinal inflammation and decreased gut microbial diversity. Such alterations in the gut microbiota resulted in the reduction of tryptophan metabolism and several tryptophan metabolites in pediatric ERA fecal samples, including indole-3-methyl acetate (PMID: 27786174). Indole-3-methyl acetate is found in apple, and has been isolated from immature seeds of beach pea (Lathyrus maritimus), Vicia amurensis, wild soybean (Glycine soja), lobiya (Vigna catiang var. sinensis) and hyacinth bean (Dolichos lablab). Isolated from immature seeds of beach pea (Lathyrus maritimus), Vicia amurensis, wild soybean (Glycine soja), lobiya (Vigna catiang variety sinensis) and hyacinth bean (Dolichos lablab). Indole-3-methyl acetate is found in many foods, some of which are gram bean, yellow wax bean, common bean, and sweet orange. Methyl 2-(1H-indol-3-yl)acetate is an endogenous metabolite.

N-Acetylleucine

C8H15NO3 (173.105188)

N-Acetyl-L-leucine or N-Acetylleucine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetylleucine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetylleucine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-lecuine. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\\% of all human proteins and 68\\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetylleucine 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 leucine can also occur. In particular, N-Acetylleucine can be biosynthesized from L-leucine and acetyl-CoA by the enzyme leucine N-acetyltransferase (EC 2.3.1.66). Excessive amounts N-acetyl amino acids including N-acetylleucine (as well as N-acetylglycine, N-acetylserine, N-acetylglutamine, N-acetylglutamate, N-acetylalanine, N-acetylmethionine and smaller amounts of N-acetylthreonine, N-acetylisoleucine, and N-acetylvaline) can be detected in the urine with individuals with acylase I deficiency, a genetic disorder (PMID: 16465618). Aminoacylase I is a soluble homodimeric zinc binding enzyme that catalyzes the formation of free aliphatic amino acids from N-acetylated precursors. In humans, Aminoacylase I is encoded by the aminoacylase 1 gene (ACY1) on chromosome 3p21 that consists of 15 exons (OMIM 609924). Individuals with aminoacylase I deficiency will experience convulsions, hearing loss and difficulty feeding (PMID: 16465618). ACY1 can also catalyze the reverse reaction, the synthesis of acetylated amino acids. Many N-acetylamino acids, including N-acetylleucine are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557).

Methyl parathion is an insecticide that does not occur naturally in the environment. Pure methyl parathion exists as white crystals. Impure methyl parathion is a brownish liquid that smells like rotten eggs.Methyl parathion is used to kill insects on farm crops, especially cotton. The EPA now restricts how methyl parathion can be used and applied; only trained people are allowed to spray it. Methyl parathion can no longer be used on food crops commonly consumed by children. Methyl parathion is a white crystalline solid which is often dissolved in a liquid solvent carrier. The commercial product is a tan liquid (xylene solution) with a pungent odor. It is slightly soluble to insoluble in water. Usually with the liquid solvent it is a combustible liquid. It is toxic by inhalation, ingestion and skin absorption. It is used as an insecticide.

Pipecolic acid

C6H11NO2 (129.0789746)

Pipecolic acid is a metabolite of lysine found in human physiological fluids such as urine, plasma and CSF. However, it is uncertain if pipecolic acid originates directly from food intake or from mammalian or intestinal bacterial enzyme metabolism. Recent studies suggest that plasma pipecolic acid, particularly the D-isomer, originates mainly from the catabolism of dietary lysine by intestinal bacteria rather than by direct food intake. In classic Zellweger syndrome (a cerebro-hepato-renal genetic disorder, OMIM 214100) pipecolic acid accumulate in the plasma of the patients. It is known that plasma pipecolic acid levels are also elevated in patients with chronic liver diseases. Pipecolic acid is moderately elevated in patients with pyridoxine-dependent seizures and might therefore be a possible biochemical marker for selecting candidates for pyridoxine therapy (Plecko et al 2000). Pipecolic acid was also elevated in CSF in these vitamin B6-responsive patients (PMID 12705501). Pipecolic acid is found to be associated with adrenoleukodystrophy, infantile Refsum disease, and peroxisomal biogenesis defect, which are also inborn errors of metabolism.

Pregnenolone

C21H32O2 (316.24021719999996)

Pregnenolone is a derivative of cholesterol, the product of cytochrome P450 side-chain cleavage (EC 1.14.15.6, CYP11A1. This reaction consists of three consecutive monooxygenations, a 22-hydroxylation, a 20-hydroxylation, and the cleavage of the C20-C22 bond, yielding pregnenolone. Pregnenolone is the precursor to gonadal steroid hormones and the adrenal corticosteroids. This reaction occurs in steroid hormone-producing tissues such as the adrenal cortex, corpus luteum, and placenta. The most notable difference between the placenta and other steroidogenic tissues is that electron supply to CYP11A1 limits the rate at which cholesterol is converted into pregnenolone in the placenta. The limiting component for electron delivery to CYP11A1 is the concentration of adrenodoxin reductase in the mitochondrial matrix which is insufficient to maintain the adrenodoxin pool in a fully reduced state. Pregnenolone is also a neurosteroid, and is produced in the spinal cord; CYP11A1 is the key enzyme catalyzing the conversion of cholesterol into pregnenolone, the rate-limiting step in the biosynthesis of all classes of steroids, and has been localized in sensory networks of the spinal cord dorsal horn. In the adrenal glomerulosa cell, angiotensin II, one of the major physiological regulators of mineralocorticoid synthesis, appears to affect most of the cholesterol transfer to the mitochondrial outer membrane and many steps in the transport to the inner membrane. Thus, it exerts a powerful control over the use of cholesterol for aldosterone production (PMID: 17222962, 15823613, 16632873, 15134809).

Pyridoxamine 5'-phosphate

C8H13N2O5P (248.05620580000001)

Pyridoxamine 5-phosphate belongs to the class of organic compounds known as pyridoxamine 5-phosphates. These are heterocyclic aromatic compounds containing a pyridoxamine that carries a phosphate group at the 5-position. Vitamin B6 is a water-soluble compound that was discovered in 1930s during nutrition studies on rats. The vitamin was named pyridoxine to indicate its structural homology to pyridine. Later it was shown that vitamin B6 could exist in two other, slightly different, chemical forms, termed pyridoxal and pyridoxamine. All three forms of vitamin B6 are precursors of an activated compound known as pyridoxal 5-phosphate (PLP), which plays a vital role as the cofactor of a large number of essential enzymes in the human body. Vitamin B6 is a water-soluble vitamin. The three major forms of vitamin B6 are pyridoxine (also known as pyridoxol), pyridoxal, and pyridoxamine, which are all converted in the liver to pyridoxal 5-phosphate (PLP) a cofactor in many reactions of amino acid metabolism. PLP also is necessary for the enzymatic reaction governing the release of glucose from glycogen. Vitamin B6 is a water-soluble compound that was discovered in 1930s during nutrition studies on rats.

S-Adenosylhomocysteine

C14H20N6O5S (384.12158300000004)

S-Adenosyl-L-homocysteine (SAH) is formed by the demethylation of S-adenosyl-L-methionine. S-Adenosylhomocysteine (AdoHcy or SAH) is also the immediate precursor of all of the homocysteine produced in the body. The reaction is catalyzed by S-adenosylhomocysteine hydrolase and is reversible with the equilibrium favoring formation of SAH. In vivo, the reaction is driven in the direction of homocysteine formation by the action of the enzyme adenosine deaminase which converts the second product of the S-adenosylhomocysteine hydrolase reaction, adenosine, to inosine. Except for methyl transfer from betaine and from methylcobalamin in the methionine synthase reaction, SAH is the product of all methylation reactions that involve S-adenosylmethionine (SAM) as the methyl donor. Methylation is significant in epigenetic regulation of protein expression via DNA and histone methylation. The inhibition of these SAM-mediated processes by SAH is a proven mechanism for metabolic alteration. Because the conversion of SAH to homocysteine is reversible, with the equilibrium favoring the formation of SAH, increases in plasma homocysteine are accompanied by an elevation of SAH in most cases. Disturbances in the transmethylation pathway indicated by abnormal SAH, SAM, or their ratio have been reported in many neurodegenerative diseases, such as dementia, depression, and Parkinsons disease (PMID:18065573, 17892439). Therefore, when present in sufficiently high levels, S-adenosylhomocysteine can act as an immunotoxin and a metabotoxin. An immunotoxin disrupts, limits the function, or destroys immune cells. A metabotoxin is an endogenous metabolite that causes adverse health effects at chronically high levels. Chronically high levels of S-adenosylhomocysteine are associated with S-adenosylhomocysteine (SAH) hydrolase deficiency and adenosine deaminase deficiency. S-Adenosylhomocysteine forms when there are elevated levels of homocysteine and adenosine. S-Adenosyl-L-homocysteine is a potent inhibitor of S-adenosyl-L-methionine-dependent methylation reactions. It is toxic to immature lymphocytes and can lead to immunosuppression (PMID:221926). S-adenosylhomocysteine, also known as adohcy or sah, is a member of the class of compounds known as 5-deoxy-5-thionucleosides. 5-deoxy-5-thionucleosides are 5-deoxyribonucleosides in which the ribose is thio-substituted at the 5position by a S-alkyl group. S-adenosylhomocysteine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). S-adenosylhomocysteine can be found in a number of food items such as rapini, european plum, rambutan, and pepper (c. pubescens), which makes S-adenosylhomocysteine a potential biomarker for the consumption of these food products. S-adenosylhomocysteine can be found primarily in blood, cerebrospinal fluid (CSF), feces, and urine, as well as throughout most human tissues. S-adenosylhomocysteine exists in all living species, ranging from bacteria to humans. In humans, S-adenosylhomocysteine is involved in several metabolic pathways, some of which include phosphatidylcholine biosynthesis PC(14:0/18:3(9Z,12Z,15Z)), phosphatidylcholine biosynthesis PC(22:4(7Z,10Z,13Z,16Z)/22:0), phosphatidylcholine biosynthesis PC(20:3(5Z,8Z,11Z)/22:2(13Z,16Z)), and phosphatidylcholine biosynthesis PC(18:3(6Z,9Z,12Z)/22:5(7Z,10Z,13Z,16Z,19Z)). S-adenosylhomocysteine is also involved in several metabolic disorders, some of which include 3-phosphoglycerate dehydrogenase deficiency, hawkinsinuria, non ketotic hyperglycinemia, and tyrosine hydroxylase deficiency. Moreover, S-adenosylhomocysteine is found to be associated with neurodegenerative disease and parkinsons disease.

Thymine

C5H6N2O2 (126.04292559999999)

Thymine, also known as 5-methyluracil, belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Thymine was first isolated in 1893 by Albrecht Kossel and Albert Neumann from calves thymus glands, hence its name. Thymine is one of the 4 nuelcoebases found in DNA and is essential to all life. Thymine exists in all living species, ranging from bacteria to plants to humans. Thymine combined with deoxyribose creates the nucleoside deoxythymidine (also called thymidine) which when phosphorylated to dTDP can be incorporated into DNA via DNA polymerases. Thymidine can be phosphorylated with up to three phosphoric acid groups, producing dTMP (deoxythymidine monophosphate) dTDP and/or dTTP. In RNA thymine is replaced with uracil in most cases. In DNA, thymine binds to adenine via two hydrogen bonds to assist in stabilizing the nucleic acid structures. Within humans, thymine participates in a number of enzymatic reactions. In particular, thymine and deoxyribose 1-phosphate can be biosynthesized from thymidine through its interaction with the enzyme thymidine phosphorylase. In addition, thymine can be converted into dihydrothymine; which is mediated by the enzyme dihydropyrimidine dehydrogenase [NADP(+)]. One of the pyrimidine bases of living matter.

Daidzein is a member of the class of 7-hydroxyisoflavones that is 7-hydroxyisoflavone substituted by an additional hydroxy group at position 4. It has a role as an antineoplastic agent, a phytoestrogen, a plant metabolite, an EC 3.2.1.20 (alpha-glucosidase) inhibitor and an EC 2.7.7.7 (DNA-directed DNA polymerase) inhibitor. It is a conjugate acid of a daidzein(1-). Daidzein is a natural product found in Pericopsis elata, Thermopsis lanceolata, and other organisms with data available. Daidzein is an isoflavone extract from soy, which is an inactive analog of the tyrosine kinase inhibitor genistein. It has antioxidant and phytoestrogenic properties. (NCI) Daidzein is one of several known isoflavones. Isoflavones compounds are found in a number of plants, but soybeans and soy products like tofu and textured vegetable protein are the primary food source. Up until recently, daidzein was considered to be one of the most important and most studied isoflavones, however more recently attention has shifted to isoflavone metabolites. Equol represents the main active product of daidzein metabolism, produced via specific microflora in the gut. The clinical effectiveness of soy isoflavones may be a function of the ability to biotransform soy isoflavones to the more potent estrogenic metabolite, equol, which may enhance the actions of soy isoflavones, owing to its greater affinity for estrogen receptors, unique antiandrogenic properties, and superior antioxidant activity. However, not all individuals consuming daidzein produce equol. Only approximately one-third to one-half of the population is able to metabolize daidzein to equol. This high variability in equol production is presumably attributable to interindividual differences in the composition of the intestinal microflora, which may play an important role in the mechanisms of action of isoflavones. But, the specific bacterial species in the colon involved in the production of equol are yet to be discovered. (A3191, A3189). See also: Trifolium pratense flower (part of).

5-Thymidylic acid

C10H15N2O8P (322.0566)

5-Thymidylic acid (conjugate base thymidylate), also known as thymidine monophosphate (TMP), deoxythymidine monophosphate (dTMP), or deoxythymidylic acid (conjugate base deoxythymidylate), is a nucleotide that is used as a monomer in DNA. It is an ester of phosphoric acid with the nucleoside thymidine. dTMP consists of a phosphate group, the pentose sugar deoxyribose, and the nucleobase thymine. Unlike the other deoxyribonucleotides, thymidine monophosphate often does not contain the "deoxy" prefix in its name; nevertheless, its symbol often includes a "d" ("dTMP"). 5-Thymidylic acid belongs to the class of organic compounds known as pyrimidine 2-deoxyribonucleoside monophosphates. These are pyrimidine nucleotides with a monophosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. The neutral species of 5-Thymidylic acid (2-deoxythymidine 5-monophosphate). 5-Thymidylic acid exists in all living species, ranging from bacteria to humans. Within humans, 5-thymidylic acid participates in a number of enzymatic reactions. In particular, 5-thymidylic acid and dihydrofolic acid can be biosynthesized from dUMP and 5,10-methylene-THF by the enzyme thymidylate synthase. In addition, 5-thymidylic acid can be converted into dTDP; which is catalyzed by the enzyme thymidylate synthase. In humans, 5-thymidylic acid is involved in pyrimidine metabolism. Outside of the human body, 5-Thymidylic acid has been detected, but not quantified in several different foods, such as common buckwheats, corn salad, garden cress, squashberries, and star fruits. 5-thymidylic acid, also known as thymidylate or thymidine 5-phosphate, is a member of the class of compounds known as pyrimidine 2-deoxyribonucleoside monophosphates. Pyrimidine 2-deoxyribonucleoside monophosphates are pyrimidine nucleotides with a monophosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. 5-thymidylic acid is slightly soluble (in water) and a moderately acidic compound (based on its pKa). 5-thymidylic acid can be found in a number of food items such as burbot, enokitake, scarlet bean, and garland chrysanthemum, which makes 5-thymidylic acid a potential biomarker for the consumption of these food products. 5-thymidylic acid can be found primarily in feces, as well as in human fibroblasts tissue. 5-thymidylic acid exists in all living species, ranging from bacteria to humans. In humans, 5-thymidylic acid is involved in the pyrimidine metabolism. 5-thymidylic 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).

Uric acid

C5H4N4O3 (168.0283394)

Uric acid is a heterocyclic purine derivative that is the final oxidation product of purine metabolism. It is a weak acid distributed throughout the extracellular fluid as sodium urate. Uric acid is produced by the enzyme xanthine oxidase, which oxidizes oxypurines such as xanthine into uric acid. In most mammals, except humans and higher primates, the enzyme uricase further oxidizes uric acid to allantoin. Interestingly, during the Miocene epoch (~15-20 million years ago), two distinct mutations in the primate genome occurred that led to a nonfunctioning uricase gene. Consequently, humans, apes, and certain New World monkeys have much higher uric acid levels (>120 μM) compared with other mammals (<<120 uM). The loss of uricase in higher primates parallels the similar loss of the ability to synthesize ascorbic acid vitamin C. This may be because in higher primates uric acid partially replaces ascorbic acid. Like ascorbic acid, uric acid is an antioxidant. In fact, in primates, uric acid is the major antioxidant in serum and is thought to be a major factor in lengthening life-span and decreasing age-specific cancer rates in humans and other primates (PMID: 6947260). Uric acid is also the end product of nitrogen metabolism in birds and reptiles. In these animal species, it is excreted in feces as a dry mass. In humans and other mammals, the amount of urate in the blood depends on the dietary intake of purines, the level of endogenous urate biosynthesis, and the rate of urate excretion. Several kidney urate transporters are involved in the regulation of plasma urate levels. These include the urate transporter 1 (URAT1), which controls the reabsorption of urate as well as a number of organic ion transporters (OAT), such as OAT1 and OAT3, and the ATP-dependent urate export transporter MRP4. URAT1 is believed to be most critical in the regulation of plasma urate levels. (PMID: 17890445) High levels of plasma uric acid lead to a condition called hyperuricemia while low levels are associated with a condition called hypouricemia. Hyperuricemia has been defined as a uric acid concentration greater than 380 μM, while hypouricemia is generally defined as a urate concentration of less than 120 μM. Hyperuricemia can arise from a number of factors, including both acute and chronic causes. Acute causes of hyperuricemia include the intake of large amounts of alcohol, tumor lysis syndrome and a diet that is rich in purines or proteins. Chronic hyperuricemia can arise from a reduction in the kidney’s glomerular filtration rate, a decrease in the excretion of urate or an increase in overall tubular absorption in the kidneys. Hyperuricemia has been linked to a number of diseases and conditions, including gout, hypertension, cardiovascular disease, myocardial infarction, stroke, and renal disease. Uric acid has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Many of the causes of hyperuricemia are correctable either with lifestyle changes or drugs. Lifestyle changes include reducing weight and reducing the consumption of protein, purines, and alcohol. There are two kinds of drugs that can be used to treat chronic hyperuricemia. Xanthine oxidase inhibitors, such as allopurinol, inhibit the production of urate by blocking urate synthesis. Alternately, uricosuric drugs, such as probenecid, sulfinpyrazone, and benzpromarone, are used to reduce the serum urate concentration through the inhibition of the URAT1 transporter. (PMID: 17890445). Uric acid (especially crystalline uric acid) is also thought to be an essential initiator and amplifier of allergic inflammation for asthma and peanut allergies (PMID: 21474346). Uric acid. CAS Common Chemistry. CAS, a division of the American Chemical Society, n.d. https://commonchemistry.cas.org/detail?cas_rn=69-93-2 (retrieved 2024-07-17) (CAS RN: 69-93-2).

Dihydrobiopterin

C9H13N5O3 (239.1018348)

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.

Diaminopimelic acid

C7H14N2O4 (190.0953524)

Diaminopimelic acid or DAPA is a lysine-like amino acid derivative that is a key component of the bacterial cell wall. DAPA is incorporated or integrated into peptidoglycan of gram negative bacteria and is the attachment point for Brauns lipoprotein (BLP or Murein Lipoprotein). BLP is found in gram-negative cell walls and is one of the most abundant membrane proteins. BLP is bound at its C-terminal end (a lysine) by a covalent bond to the peptidoglycan layer (specifically to diaminopimelic acid molecules) and is embedded in the outer membrane by its hydrophobic head (a cysteine with lipids attached). BLP tightly links the two layers and provides structural integrity to the bacterial outer membrane. Diaminopimelic acid can be found in human urine or feces due to the lysis or enzymatic breakdown of gram negative gut microbes.

Deoxyinosine

C10H12N4O4 (252.08585119999998)

Deoxyinosine is a nucleoside that is formed when hypoxanthine is attached to a deoxyribose ring (also known as a ribofuranose) via a beta-N9-glycosidic bond. Deoxyinosine is found in DNA while inosine is found in RNA. Inosine is a nucleic acid important for RNA editing. Adenosine deaminase (ADA) catalyzes the conversion of adenosine and deoxyadenosine to inosine and deoxyinosine, respectively. ADA-deficient individuals suffer from severe combined immunodeficiency (SCID) and are unable to produce significant numbers of mature T or B lymphocytes. This occurs as a consequence of the accumulation of ADA substrates or their metabolites. Inosine is also an intermediate in a chain of purine nucleotides reactions required for muscle movements. Moreover, deoxyinosine is found to be associated with purine nucleoside phosphorylase (PNP) deficiency, which is an inborn error of metabolism. Isolated from Phaseolus vulgaris (kidney bean). 2-Deoxyinosine is found in pulses, yellow wax bean, and green bean.

Gluconic acid

C6H12O7 (196.0583002)

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

Isoniazid

C6H7N3O (137.0589092)

Isoniazid (also called isonicotinyl hydrazine or INH; sold as Laniazid, Nydrazid) is an organic compound that is the first-line antituberculosis medication in prevention and treatment. First discovered in 1912 as an inhibitor of the MAO enzyme, it was first used as an antidepressant, but discontinued due to side effects. In 1951, it was later discovered that isoniazid was effective against TB. Isoniazid is never used on its own to treat active tuberculosis because resistance quickly develops.; Isoniazid is a bactericidal agent active against organisms of the genus Mycobacterium, specifically M. tuberculosis, M. bovis and M. kansasii. It is a highly specific agent, ineffective against other microorganisms. Isoniazid is bactericidal to rapidly-dividing mycobacteria, but is bacteriostatic if the mycobacterium is slow-growing.; Isoniazid is a prodrug and must be activated by bacterial catalase. It is activated by catalase-peroxidase enzyme KatG which couples the isonicotinic acyl with NADH to form isonicotinic acyl-NADH complex. This complex binds tightly to ketoenoylreductase known as InhA, thereby blocking the natural enoyl-AcpM substrate and the action of fatty acid synthase. This process inhibits the synthesis of mycolic acid required for the mycobacterial cell wall. A range of radicals are produced by KatG activation of Isoniazid, including nitric oxide, that has also been shown to be important in the action of another antimycobacterial prodrug PA824. [HMDB] Isoniazid is only found in individuals that have used or taken this drug. It is an antibacterial agent used primarily as a tuberculostatic. It remains the treatment of choice for tuberculosis. [PubChem]Isoniazid is a prodrug and must be activated by bacterial catalase. Specficially, activation is associated with reduction of the mycobacterial ferric KatG catalase-peroxidase by hydrazine and reaction with oxygen to form an oxyferrous enzyme complex. Once activated, isoniazid inhibits the synthesis of mycoloic acids, an essential component of the bacterial cell wall. At therapeutic levels isoniazid is bacteriocidal against actively growing intracellular and extracellular Mycobacterium tuberculosis organisms. Specifically isoniazid inhibits InhA, the enoyl reductase from Mycobacterium tuberculosis, by forming a covalent adduct with the NAD cofactor. It is the INH-NAD adduct that acts as a slow, tight-binding competitive inhibitor of InhA.

Porphobilinogen

C10H14N2O4 (226.0953524)

Porphobilinogen (PBG) is a pyrrole-containing intermediate in the biosynthesis of porphyrins. It is generated from aminolevulinate (ALA) by the enzyme ALA dehydratase. Porphobilinogen is then converted into hydroxymethylbilane by the enzyme porphobilinogen deaminase (also known as hydroxymethylbilane synthase). Under certain conditions, porphobilinogen can act as a phototoxin, a neurotoxin, and a metabotoxin. A phototoxin leads to cell damage upon exposure to light. 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 porphyrins are associated with porphyrias such as porphyria variegate, acute intermittent porphyria, and hereditary coproporphyria (HCP). There are several types of porphyrias (most are inherited). Hepatic porphyrias are characterized by acute neurological attacks (seizures, psychosis, extreme back and abdominal pain, and an acute polyneuropathy), while the erythropoietic forms present with skin problems (usually a light-sensitive blistering rash and increased hair growth). The neurotoxicity of porphyrins may be due to their selective interactions with tubulin, which disrupt microtubule formation and cause neural malformations (PMID: 3441503). Porphobilinogen is a pyrrole involved in porphyrin metabolism. -- Wikipedia; It consists of a pyrrole ring with acetyl, propionyl, and aminomethyl side chains; It is a key monopyrrolic intermediate in porphyrin, chlorophyll and vitamin B12 biosynthesis. Porphobilinogen is generated by the enzyme ALA dehydratase by combining two molecules of dALA together, and converted into hydroxymethyl bilane by the enzyme porphobilinogen deaminase. 4 molecules of porphobilinogen are condensed to form one molecule of uroporphyrinogen III, which is then converted successively to coproporphyrinogen III, protoporphyrin IX, and heme. Porphobilinogen is produced in excess and excreted in the urine in acute intermittent porphyria and several other porphyrias. [HMDB]. Porphobilinogen is found in many foods, some of which are strawberry guava, amaranth, parsnip, and ostrich fern.

Glycerol 3-phosphate

C3H9O6P (172.01367439999999)

Glycerol 3-phosphate, also known as glycerophosphoric acid or alpha-glycerophosphorate, is a member of the class of compounds known as glycerophosphates. Glycerophosphates are compounds containing a glycerol linked to a phosphate group. Glycerol 3-phosphate is soluble (in water) and a moderately acidic compound (based on its pKa). Glycerol 3-phosphate can be found in a number of food items such as sacred lotus, common oregano, mixed nuts, and yautia, which makes glycerol 3-phosphate a potential biomarker for the consumption of these food products. Glycerol 3-phosphate can be found primarily in blood, feces, saliva, and urine, as well as in human prostate tissue. Glycerol 3-phosphate exists in all living species, ranging from bacteria to humans. In humans, glycerol 3-phosphate is involved in several metabolic pathways, some of which include cardiolipin biosynthesis cl(i-12:0/i-21:0/a-21:0/i-21:0), cardiolipin biosynthesis cl(i-12:0/a-25:0/i-13:0/i-12:0), cardiolipin biosynthesis cl(i-13:0/i-21:0/i-21:0/a-25:0), and cardiolipin biosynthesis cl(i-13:0/a-25:0/i-18:0/a-13:0). Glycerol 3-phosphate is also involved in several metabolic disorders, some of which include de novo triacylglycerol biosynthesis tg(i-24:0/19:0/16:0), de novo triacylglycerol biosynthesis TG(16:0/22:4(7Z,10Z,13Z,16Z)/16:1(9Z)), de novo triacylglycerol biosynthesis TG(18:0/18:3(9Z,12Z,15Z)/14:1(9Z)), and de novo triacylglycerol biosynthesis TG(18:3(6Z,9Z,12Z)/22:5(4Z,7Z,10Z,13Z,16Z)/20:2(11Z,14Z)). Glycerol 3-phosphate is a chemical intermediate in the glycolysis metabolic pathway. It is commonly confused with the similarly named glycerate 3-phosphate or glyceraldehyde 3-phosphate. Glycerol 3-phosphate is produced from glycerol, the triose sugar backbone of triglycerides and glycerophospholipids, by the enzyme glycerol kinase. Glycerol 3-phospate may then be converted by dehydrogenation to dihydroxyacetone phosphate (DHAP) by the enzyme glycerol-3-phosphate dehydrogenase. DHAP can then be rearranged into glyceraldehyde 3-phosphate (GA3P) by triose phosphate isomerase (TIM), and feed into glycolysis. The glycerol 3-phosphate shuttle is used to rapidly regenerate NAD+ in the brain and skeletal muscle cells of mammals (wikipedia).

D-Glucuronate

C6H10O7 (194.042651)

Glucuronic acid (CAS: 6556-12-3) is a carboxylic acid that has the structure of a glucose molecule that has had its sixth carbon atom (of six total) oxidized. The salts of glucuronic acid are known as glucuronates. Glucuronic acid is highly soluble in water. In humans, glucuronic acid is often linked to toxic or poisonous substances to allow for subsequent elimination, and to hormones to allow for easier transport. These linkages involve O-glycosidic bonds. The process is known as glucuronidation, and the resulting substances are known as glucuronides (or glucuronosides). Glucuronidation uses UDP-glucuronic acid (glucuronic acid linked via a glycosidic bond to uridine diphosphate) as an intermediate. UDP-glucuronic acid is formed in the liver of all animals. D-Glucuronic acid is an important intermediate isolated from many gums. D-Glucuronic acid and its derivative glucuronolactone are as a liver antidote in the prophylaxis of human health. D-Glucuronic acid has an anti-inflammatory effect for the skin[1]. D-Glucuronic acid is an important intermediate isolated from many gums.

Glucosamine

C6H13NO5 (179.0793688)

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

Pyroglutamic acid

C5H7NO3 (129.0425912)

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

Aflatoxin B1

C17H12O6 (312.06338519999997)

Aflatoxins are naturally occurring mycotoxins that are produced by many species of Aspergillus, a fungus. At least 13 different types of aflatoxin are produced in nature. Aflatoxin B1 is considered the most toxic and is produced by both Aspergillus flavus and Aspergillus parasiticus. The native habitat of Aspergillus is in soil, decaying vegetation, hay, and grains undergoing microbiological deterioration and it invades all types of organic substrates whenever conditions are favourable for its growth. Favourable conditions include high moisture content (at least 7\\\%) and high temperature. Aflatoxins B1 (AFB1) are contaminants of improperly stored foods; they are potent genotoxic and carcinogenic compounds, exerting their effects through damage to DNA. They can also induce mutations that increase oxidative damage (PMID: 17214555). Crops which are frequently affected by Aspergillus contamination include cereals (maize, sorghum, pearl millet, rice, wheat), oilseeds (peanut, soybean, sunflower, cotton), spices (chile peppers, black pepper, coriander, turmeric, ginger), and tree nuts (almond, pistachio, walnut, coconut, brazil nut).

Aicar is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Aicar can be found in a number of food items such as safflower, greenthread tea, common pea, and wild leek, which makes aicar a potential biomarker for the consumption of these food products. Aicar can be found primarily in saliva, as well as in human skeletal muscle tissue. Aicar exists in all living species, ranging from bacteria to humans. In humans, aicar is involved in few metabolic pathways, which include azathioprine action pathway, mercaptopurine action pathway, purine metabolism, and thioguanine action pathway. Aicar is also involved in several metabolic disorders, some of which include mitochondrial DNA depletion syndrome, purine nucleoside phosphorylase deficiency, xanthinuria type II, and gout or kelley-seegmiller syndrome. AICAR also known as ZMP is an analog of AMP that is capable of stimulating AMP-dependent protein kinase activity(AMPK). AICAR is an intermediate in the generation of inosine monophosphate. AICAR is being clinically used to treat and protect against cardiac ischemic injury. AICAR can enter cardiac cells to inhibit adenosine kinase and adenosine deaminase. It enhances the rate of nucleotide re-synthesis increasing adenosine generation from adenosine monophosphate only during conditions of myocardial ischemia. AICAR increases glucose uptake by inducing translocation of GLUT4 and/or by activating the p38 MAPK pathway. Acquisition and generation of the data is financially supported in part by CREST/JST.

D-Xylose

C5H10O5 (150.052821)

Xylose or wood sugar is an aldopentose - a monosaccharide containing five carbon atoms and an aldehyde functional group. It has chemical formula C5H10O5 and is 40\\\\% as sweet as sucrose. Xylose is found in the embryos of most edible plants. The polysaccharide xylan, which is closely associated with cellulose, consists practically entirely of d-xylose. Corncobs, cottonseed hulls, pecan shells, and straw contain considerable amounts of this sugar. Xylose is also found in mucopolysaccharides of connective tissue and sometimes in the urine. Xylose is the first sugar added to serine or threonine residues during proteoglycan type O-glycosylation. Therefore xylose is involved in the biosythetic pathways of most anionic polysaccharides such as heparan sulphate and chondroitin sulphate. In medicine, xylose is used to test for malabsorption by administering a xylose solution to the patient after fasting. If xylose is detected in the blood and/or urine within the next few hours, it has been absorbed by the intestines. Xylose is said to be one of eight sugars which are essential for human nutrition, the others being galactose, glucose, mannose, N-acetylglucosamine, N-acetylgalactosamine, fucose, and sialic acid. (Wikipedia). Xylose in the urine is a biomarker for the consumption of apples and other fruits. Xylose is a sugar first isolated from wood, and named for it. Xylose is classified as a monosaccharide of the aldopentose type, which means that it contains five carbon atoms and includes an aldehyde functional group. It is the precursor to hemicellulose, one of the main constituents of biomass. D-Xylopyranose is found in flaxseed. D-(+)-xylose (Xylose) is a natural compound that is catalyzed by xylose isomerase to form xylulose, which is a key step in the anaerobic ethanol fermentation of xylose.

Quetiapine

C21H25N3O2S (383.166739)

The most common side effect is sedation, and is prescribed specifically for this effect in patients with sleep disorders. Seroquel will put the patient into a drowsy state, and will help the patient fall asleep. It is one of the most sedating of all anti psychotic drugs, rivaling even the most sedating older antipsychotics. Many prescriptions call for the entire dose to be taken before bedtime because of its sedative effects. Although quetiapine is approved by the FDA for the treatment of schizophrenia and bipolar disorder, it is frequently prescribed for off-label purposes including insomnia or the treatment of anxiety disorders. Due to its sedative side effects, reports of quetiapine abuse (sometimes by insufflating crushed tablets) have emerged in medical literature; Quetiapine belongs to a series of neuroleptics known as "atypical antipsychotics", which have become increasingly popular alternatives to "typical antipsychotics" such as haloperidol. Quetiapine HAS approvals for the treatment of schizophrenia and acute mania in bipolar disorder.

Sterigmatocystin

C18H12O6 (324.06338519999997)

Sterigmatocystin is a mycotoxin of Aspergillus versicolor and Chaetomium species Sterigmatocystin is a poison of the type dermatoxin, from the fungi genus Aspergillus. It appears on crusts of cheese with mold. Sterigmatocystin is a toxic metabolite structurally closely related to the aflatoxins (compare general fact sheet number 2), and consists of a xanthone nucleus attached to a bifuran structure. Sterigmatocystin is mainly produced by the fungi Aspergillus nidulans and A. versicolor. It has been reported in mouldy grain, green coffee beans and cheese although information on its occurrence in foods is limited. It appears to occur much less frequently than the aflatoxins, although analytical methods for its determination have not been as sensitive until recently, and so it is possible that small concentrations in food commodities may not always have been detected. Although it is a potent liver carcinogen similar to aflatoxin B1, current knowledge suggests that it is nowhere near as widespread in its occurrence. If this is the true situation it would be justified to consider sterigmatocystin as no more than a risk to consumers in special or unusual circumstances. Sterigmatocystin is a number of closely related compounds such o-methyl sterigmatocystin are known and some may also occur naturally. The IARC-classification of sterigmatocystin is group 2B, which means it is possibly carcinogenic to humans. In practice, the risk is quite low however, because this substance only appears on cheese crusts with mold, and because of that the chance of daily exposure is very low. Sterigmatocystin is a molded crust is best not to be consumed in whole, but after removing the crust, the cheese can still be consumed. Sterigmatocystin is a different kind of mold than that which appears on cheese itself, which can simply be removed before further consumption D009676 - Noxae > D011042 - Poisons > D009183 - Mycotoxins CONFIDENCE Reference Standard (Level 1); INTERNAL_ID 2320

Ethionamide

C8H10N2S (166.056466)

Ethionamide is only found in individuals that have used or taken this drug. It is a second-line antitubercular agent that inhibits mycolic acid synthesis. It also may be used for treatment of leprosy. (From Smith and Reynard, Textbook of Pharmacology, 1992, p868)Ethionamide may be bacteriostatic or bactericidal in action, depending on the concentration of the drug attained at the site of infection and the susceptibility of the infecting organism. Ethionamide, like prothionamide and pyrazinamide, is a nicotinic acid derivative related to isoniazid. It is thought that ethionamide undergoes intracellular modification and acts in a similar fashion to isoniazid. Isoniazid inhibits the synthesis of mycoloic acids, an essential component of the bacterial cell wall. Specifically isoniazid inhibits InhA, the enoyl reductase from Mycobacterium tuberculosis, by forming a covalent adduct with the NAD cofactor. It is the INH-NAD adduct that acts as a slow, tight-binding competitive inhibitor of InhA. Ethionamide. CAS Common Chemistry.

Oxidized glutathione

C20H32N6O12S2 (612.1519552)

Oxidized glutathione, also known as glutathione disulfide or GSSG, belongs to the class of organic compounds known as peptides. Peptides are compounds containing an amide derived from two or more amino carboxylic acid molecules (the same or different) by the formation of a covalent bond from the carbonyl carbon of one to the nitrogen atom of another. In humans, oxidized glutathione is involved in the metabolic disorder called leukotriene C4 synthesis deficiency pathway. Outside of the human body, oxidized glutathione has been detected, but not quantified in several different foods, such as leeks, star anises, mamey sapotes, climbing beans, and common persimmons. Oxidized glutathione is a glutathione dimer formed by a disulfide bond between the cysteine sulfhydryl side chains during the course of being oxidized. Glutathione participates in leukotriene synthesis and is a cofactor for the enzyme glutathione peroxidase. It is also important as a hydrophilic molecule that is added to lipophilic toxins and waste in the liver during biotransformation before they can become part of the bile. Glutathione is also needed for the detoxification of methylglyoxal, a toxin produced as a by-product of metabolism. This detoxification reaction is carried out by the glyoxalase system. Glyoxalase I (EC 4.4.1.5) catalyzes the conversion of methylglyoxal and reduced glutathione into S-D-lactoyl-glutathione. Glyoxalase II (EC 3.1.2.6) catalyzes the hydrolysis of S-D-lactoyl-glutathione into glutathione and D-lactate. Glutathione disulfide (GSSG) - oxidized glutathione - is a disulfide derived from two glutathione molecules. In living cells, glutathione disulfide is reduced into two molecules of glutathione with reducing equivalents from the coenzyme NADPH. This reaction is catalyzed by the enzyme glutathione reductase. [Wikipedia]. Glutathione disulfide is found in many foods, some of which are jute, millet, malabar plum, and acorn.

4-Nitrophenol

C6H5NO3 (139.02694200000002)

4-Nitrophenol (also called p-nitrophenol or 4-hydroxynitrobenzene) is a phenolic compound that has a nitro group at the opposite position of the hydroxyl group on the benzene ring. It belongs to the class of organic compounds known as nitrophenols. Nitrophenols are compounds containing a nitrophenol moiety, which consists of a benzene ring bearing both a hydroxyl group and a nitro group on two different ring carbon atoms. 4-Nitrophenol shows two polymorphs in the crystalline state. The alpha-form is colorless pillars, unstable at room temperature, and stable toward sunlight. The beta-form is yellow pillars, stable at room temperature, and gradually turns red upon irradiation of sunlight. Usually 4-nitrophenol exists as a mixture of these two forms. 4-Nitrophenol can be used as a pH indicator and as an intermediate in the synthesis of paracetamol. Itis also used as the precursor for the preparation of phenetidine and acetophenetidine, indicators, and raw materials for fungicides. Bioaccumulation of this compound rarely occurs. In peptide synthesis, carboxylate ester derivatives of 4-nitrophenol may serve as activated components for construction of amide moieties. 4-Nitrophenol is a potentially toxic compound: it can cause eyes, skin, and respiratory tract irritations. It may also cause inflammation of those parts. It has a delayed interaction with blood and forms methaemoglobin which is responsible for methemoglobinemia -which is characterized by tissue hypoxia, as methemoglobin cannot bind oxygen-, potentially causing cyanosis, confusion, and unconsciousness. When ingested, it causes abdominal pain and vomiting. Prolonged contact with skin may cause allergic response. Genotoxicity and carcinogenicity of 4-nitrophenol are not known.

Diethylthiophosphate

C4H11O3PS (170.0166506)

Diethylthiophosphate, also known as DETP, belongs to the class of organic compounds known as thiophosphate diesters. These are organic compounds containing the thiophosphoric acid functional group or a derivative thereof, with the general structure ROP(OR)(OR)=S, where exactly two R-groups are organyl groups. The glutathione transferase reactions produce products that are, in most cases, of low toxicity. Diethylthiophosphate is a potentially toxic compound. Acute OP intoxication results from blockage of the decomposition of synaptic acetylcholine because the pesticide covalently binds to chlolinesterase Chronic exposure to POs has neurological sequelae as well and data suggests that OP exposure alters sperm chromatin condensation (A3181, A3182, A3183, A3181). Chronic exposure to POs has neurological sequelae as well (PMID 8179040) and data suggests that OP exposure alters sperm chromatin condensation (PMID 15050412). PON1 hydrolyzes the active metabolites in several organophosphates insecticides as well as, nerve agents such as soman, sarin, and VX. Metabolism of organophosphates occurs principally by oxidation, by hydrolysis via esterases and by reaction with glutathione. Acute OP intoxication results from blockage of the decomposition of synaptic acetylcholine because the pesticide covalently binds to chlolinesterase (PMID 11991535). Diethylthiophosphate is the most frequent metabolite of organophosphorus (OP) found in urine (PMID 15050412). Organophosphorus compounds are widely used as pesticides because of easy degradation in the environment. Acute OP intoxication results from blockage of the decomposition of synaptic acetylcholine because the pesticide covalently binds to chlolinesterase (PMID 11991535).

Phytosphingosine

C18H39NO3 (317.29297840000004)

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

Flavin mononucleotide

C17H21N4O9P (456.10461060000006)

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

Inosinic acid

C10H13N4O8P (348.0470988)

Inosinic acid, also known as inosine monophosphate, IMP, 5-inosinate or 5-IMP, belongs to the class of organic compounds known as purine ribonucleoside monophosphates. These are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. IMP is also classified as a nucleotide (a nucleoside monophosphate). Inosinic acid exists in all living species, ranging from bacteria to plants to humans. IMP is widely used as a flavor enhancer. In the food industry it is known as E number reference E630. Inosinic acid can be converted into various salts including disodium inosinate (E631), dipotassium inosinate (E632), and calcium inosinate (E633). These three inosinate compounds are used as flavor enhancers for the basic taste umami. These inosinate salts are mostly used in soups, sauces, and seasonings for the intensification and balance of the flavor of meat. Inosinic acid is typically obtained from chicken byproducts or other meat industry waste. Inosinic acid or IMP is important in metabolism. It is the ribonucleotide of hypoxanthine and the first nucleotide formed during the synthesis of purine nucleotides. It can also be formed by the deamination of adenosine monophosphate by AMP deaminase. GMP is formed by the inosinate oxidation to xanthylate (XMP). Within humans, inosinic acid participates in a number of enzymatic reactions. In particular, inosinic acid can be converted into phosphoribosyl formamidocarboxamide; which is catalyzed by the bifunctional purine biosynthesis protein.

Cytidine monophosphate

C9H14N3O8P (323.05184940000004)

Cytidine monophosphate, also known as 5-cytidylic acid and abbreviated CMP, is a nucleotide. It is an ester of phosphoric acid with the nucleoside cytidine. CMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase cytosine. Cytidine monophosphate (CMP) is derived from cytidine triphosphate (CTP) with subsequent loss of two phosphates. The synthesis of the pyrimidines CTP and UTP occurs in the cytoplasm and starts with the formation of carbamoyl phosphate from glutamine and CO2. Next, aspartate undergoes a condensation reaction with carbamoyl-phosphate to form orotic acid. In a subsequent cyclization reaction, the enzyme Aspartate carbamoyltransferase forms N-carbamoyl-aspartate which is converted into dihydroorotic acid by Dihydroorotase. The latter is converted to orotate by Dihydroorotate oxidase. Orotate is covalently linked with a phosphorylated ribosyl unit with Orotate phosphoribosyltransferase (aka "PRPP transferase") catalyzing reaction, yielding orotidine monophosphate (OMP). Orotidine-5-phosphate is decarboxylated by Orotidine-5-phosphate decarboxylase to form uridine monophosphate (UMP). UMP is phosphorylated by two kinases to uridine triphosphate (UTP) via two sequential reactions with ATP. CTP is subsequently formed by amination of UTP by the catalytic activity of CTP synthetase. Cytosine monophosphate (CMP) and uridine monophosphate (UMP) have been prescribed for the treatment of neuromuscular affections in humans. Patients treated with CMP/UMP recover from altered neurological functions. Additionally, the administration of CMP/UMP appears to favour the entry of glucose in the muscle and CMP/UMP may be important in maintaining the level of hepatic glycogen constant during exercise. [PMID:18663991]. Cytidine monophosphate, also known as cmp or cytidylic acid, is a member of the class of compounds known as pyrimidine ribonucleoside monophosphates. Pyrimidine ribonucleoside monophosphates are pyrimidine ribobucleotides with monophosphate group linked to the ribose moiety. Cytidine monophosphate is soluble (in water) and a moderately acidic compound (based on its pKa). Cytidine monophosphate can be found in a number of food items such as elliotts blueberry, small-leaf linden, orange mint, and malabar spinach, which makes cytidine monophosphate a potential biomarker for the consumption of these food products. Cytidine monophosphate can be found primarily in saliva, as well as throughout all human tissues. Cytidine monophosphate exists in all living species, ranging from bacteria to humans. In humans, cytidine monophosphate is involved in several metabolic pathways, some of which include cardiolipin biosynthesis cl(i-13:0/i-18:0/i-17:0/18:2(9z,11z)), cardiolipin biosynthesis cl(i-13:0/i-24:0/a-21:0/i-15:0), cardiolipin biosynthesis cl(i-13:0/i-22:0/i-20:0/i-15:0), and cardiolipin biosynthesis cl(i-12:0/a-17:0/i-20:0/a-21:0).

Thiamine

[C12H17N4OS]+ (265.1123012)

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

C7H13NO2 (143.0946238)

Proline betaine is an osmoprotective compound found in urine. It is thought to serve an osmoprotective role for the kidney. Proline betaine is a glycine betaine analogue found in many citrus foods. Elevated levels of proline betaine in human urine are found after the consumption of citrus fruits and juices (PMID: 18060588). Proline betaine is a biomarker for the consumption of citrus fruits. Alkaloid from Citrus spp Medicago sativa and Stachys subspecies(alfalfa). L-Stachydrine or also called proline betaine is a biomarker for the consumption of citrus fruits. L-Stachydrine is found in many foods, some of which are capers, pulses, lemon, and alfalfa. Proline betaine, also known as stachydrine, belongs to the class of organic compounds known as proline and derivatives. Proline and derivatives 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 betaine exists in all living organisms, ranging from bacteria to humans. Proline betaine is found, on average, in the highest concentration within capers (Capparis spinosa). Proline betaine has also been detected, but not quantified in, several different foods, such as soy beans (Glycine max), crosnes (Stachys affinis), domestic pigs (Sus scrofa domestica), limes (Citrus aurantiifolia), and triticales (X Triticosecale rimpaui). This could make proline betaine a potential biomarker for the consumption of these foods. Proline betaine is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Proline betaine. Stachydrine is a major constituent of Chinese herb leonurus heterophyllus sweet used to promote blood circulation and dispel blood stasis. Stachydrine can inhibit the NF-κB signal pathway.

Guanosine monophosphate (GMP), also known as 5′-guanidylic acid or guanylic acid (conjugate base guanylate), is a nucleotide that is used as a monomer in RNA. It is an ester of phosphoric acid with the nucleoside guanosine. GMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase guanine; hence it is a ribonucleoside monophosphate. Guanosine monophosphate is commercially produced by microbial fermentation. Guanosine monophosphate, also known as guanylic acid or 5-GMP, belongs to the class of organic compounds known as purine ribonucleoside monophosphates. These are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. A guanine nucleotide containing one phosphate group esterified to the sugar moiety and found widely in nature. Guanosine monophosphate exists in all living species, ranging from bacteria to humans. Within humans, guanosine monophosphate participates in a number of enzymatic reactions. In particular, guanosine triphosphate and guanosine monophosphate can be biosynthesized from diguanosine tetraphosphate through its interaction with the enzyme bis(5-nucleosyl)-tetraphosphatase [asymmetrical]. In addition, guanosine monophosphate can be biosynthesized from guanosine diphosphate; which is mediated by the enzyme ectonucleoside triphosphate diphosphohydrolase 5. In humans, guanosine monophosphate is involved in the metabolic disorder called the lesch-nyhan syndrome (lns) pathway. Outside of the human body, guanosine monophosphate has been detected, but not quantified in several different foods, such as common cabbages, tea, winter squash, spearmints, and sugar apples. Guanosine-5-monophosphate, also known as 5-gmp or guanylic acid, is a member of the class of compounds known as purine ribonucleoside monophosphates. Purine ribonucleoside monophosphates are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. Guanosine-5-monophosphate is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Guanosine-5-monophosphate can be found in a number of food items such as mustard spinach, swiss chard, watercress, and colorado pinyon, which makes guanosine-5-monophosphate a potential biomarker for the consumption of these food products. Guanosine-5-monophosphate can be found primarily in blood and saliva, as well as throughout most human tissues. Guanosine-5-monophosphate exists in all living species, ranging from bacteria to humans. In humans, guanosine-5-monophosphate is involved in several metabolic pathways, some of which include clarithromycin action pathway, erythromycin action pathway, minocycline action pathway, and tetracycline action pathway. Guanosine-5-monophosphate is also involved in several metabolic disorders, some of which include gout or kelley-seegmiller syndrome, xanthine dehydrogenase deficiency (xanthinuria), aICA-Ribosiduria, and molybdenum cofactor deficiency. Guanosine monophosphate is known as E number reference E626.[7] In the form of its salts, such as disodium guanylate (E627), dipotassium guanylate (E628) and calcium guanylate (E629), are food additives used as flavor enhancers to provide the umami taste.[7] It is often used in synergy with disodium inosinate; the combination is known as disodium 5′-ribonucleotides. Disodium guanylate is often found in instant noodles, potato chips and snacks, savoury rice, tinned vegetables, cured meats, and packet soup. As it is a fairly expensive additive, it is usually not used independently of glutamic acid or monosodium glutamate (MSG), which also contribute umami. If inosinate and guanylate salts are present in a list of ingredients but MSG does not appear to be, the glutamic acid is likely provided as part of another ingredient, such as a processed soy protein complex (hydrolyzed soy protein), autolyzed yeast, or soy sauce. 5'-Guanylic acid (5'-GMP) is involved in several metabolic disorders, including the AICA-ribosiduria pathway, adenosine deaminase deficiency, adenine phosphoribosyltransferase deficiency (aprt), and the 2-hydroxyglutric aciduria pathway. 5'-Guanylic acid (5'-GMP) is involved in several metabolic disorders, including the AICA-ribosiduria pathway, adenosine deaminase deficiency, adenine phosphoribosyltransferase deficiency (aprt), and the 2-hydroxyglutric aciduria pathway.

The phosphoric acid ester of serine. As a constituent (residue) of proteins, its side chain can undergo O-linked glycosylation. This might be important in explaining some of the devastating consequences of diabetes. It is one of three amino acid residues that are commonly phosphorylated by kinases during cell signalling in eukaryotes. Phosphorylated serine residues are often referred to as phosphoserine. Serine proteases are a common type of protease. Serine, organic compound, one of the 20 amino acids commonly found in animal proteins. Only the L-stereoisomer appears in mammalian protein. It is not essential to the human diet, since it can be synthesized in the body from other metabolites, including glycine. Serine was first obtained from silk protein, a particularly rich source, in 1865. Its name is derived from the Latin for silk, sericum. Serines structure was established in 1902. [HMDB] Phosphoserine is the phosphoric acid ester of the amino acid serine. It is found in essentially all living organisms ranging from microbes to plants to mammals. Phosphoserine is a component of many proteins as the result of posttranslational modifications to the native protein’s serine residue(s).

Phosphorylcholine, also known as choline phosphate or N-trimethyl-2-aminoethylphosphonate, is a member of the class of compounds known as phosphocholines. Phosphocholines are compounds containing a [2-(trimethylazaniumyl)ethoxy]phosphonic acid or derivative. Phosphorylcholine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Phosphorylcholine can be found in a number of food items such as grapefruit, lime, black cabbage, and barley, which makes phosphorylcholine a potential biomarker for the consumption of these food products. Phosphorylcholine can be found primarily in most biofluids, including urine, blood, saliva, and cerebrospinal fluid (CSF), as well as throughout most human tissues. Phosphorylcholine exists in all eukaryotes, ranging from yeast to humans. In humans, phosphorylcholine is involved in several metabolic pathways, some of which include phosphatidylcholine biosynthesis PC(13D5/9D5), phosphatidylcholine biosynthesis PC(22:5(4Z,7Z,10Z,13Z,16Z)/22:5(7Z,10Z,13Z,16Z,19Z)), phosphatidylcholine biosynthesis PC(14:0/20:1(11Z)), and phosphatidylcholine biosynthesis PC(11D5/9D5).

Moreover, phosphorylcholine is found to be associated with alzheimers disease and multi-infarct dementia. Phosphorylcholine (abbreviated ChoP) is the hydrophilic polar head group of some phospholipids, which is composed of a negatively charged phosphate bonded to a small, positively charged choline group. Phosphorylcholine is part of platelet-activating factor; the phospholipid phosphatidylcholine as well as sphingomyelin, the only phospholipid of the membrane that is not built with a glycerol backbone. Treatment of cell membranes, like those of RBCs, by certain enzymes, like some phospholipase A2 renders the phosphorylcholine moiety exposed to the external aqueous phase, and thus accessible for recognition by the immune system. Antibodies against phosphorylcholine are naturally occurring autoantibodies that are created by CD5+/B-1 B cells and are referred to as non-pathogenic autoantibodies . Phosphorylcholine, also known as choline phosphate or CHOP, belongs to the class of organic compounds known as phosphocholines.

Dehydroascorbic acid

C6H6O6 (174.01643760000002)

Dehydroascorbic acid (DHA) is an oxidized form of ascorbic acid (vitamin C). It is actively imported into the endoplasmic reticulum of cells via glucose transporters. It is trapped therein by reduction back to ascorbate by glutathione and other thiols. Dehydroascorbic acid, also known as L-dehydroascorbate or DHAA, belongs to the class of organic compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. Dehydroascorbic acid has similar biological activity as ascorbic acid. Currently dehydroascorbic acid is an experimental drug with no known approved indications. Dehydroascorbic acid may be a unique E. coli metabolite. Norepinephrine and dehydroascorbic acid can be biosynthesized from dopamine and ascorbic acid through its interaction with the enzyme dopamine beta-hydroxylase. In humans, dehydroascorbic acid is involved in the metabolic disorder called tyrosinemia type I. Concerning dehydroascorbic acids antiviral effect against herpes simplex virus type 1, it is suggested that dehydroascorbic acid acts after replication of viral DNA and prevents the assembly of progeny virus particles. This is important because one study has found that after an ischemic stroke, dehydroascorbic acid has neuroprotective effects by reducing infarct volume, neurological deficits, and mortality. This reaction is reversible, but dehydroascorbic acid can instead undergo irreversible hydrolysis to 2,3-diketogulonic acid. In addition, unlike ascorbic Dehydroascorbic acid acid can cross the blood brain barrier and is then converted to ascorbic acid to enable retention in the brain. Dehydroascorbic acid is made from the oxidation of ascorbic acid. The exact mechanism of action is still being investigated, but some have been elucidated. Both compounds have been shown to have antiviral effects against herpes simplex virus type 1, influenza virus type A and poliovirus type 1 with dehydroascorbic acid having the stronger effect. In the body, both dehydroascorbic acid and ascorbic acid have similar biological activity as antivirals but dehydroascorbic acid also has neuroprotective effects. Even though dehydroascorbic acid and ascorbic acid have similar effects, their mechanism of action seems to be different. Dehydroascorbic acid, also known as dehydroascorbate, is a member of the class of compounds known as gamma butyrolactones.

alpha-Ketoisovaleric acid

C5H8O3 (116.0473418)

alpha-Ketoisovaleric acid is an abnormal metabolite that arises from the incomplete breakdown of branched-chain amino acids. alpha-Ketoisovaleric acid is a neurotoxin, an acidogen, and a metabotoxin. A neurotoxin causes damage to nerve cells and nerve tissues. 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 alpha-ketoisovaleric acid are associated with maple syrup urine disease. MSUD is a metabolic disorder caused by a deficiency of the branched-chain alpha-keto acid dehydrogenase complex (BCKDC), leading to a buildup of the branched-chain amino acids (leucine, isoleucine, and valine) and their toxic by-products (ketoacids) in the blood and urine. The symptoms of MSUD often show in infancy and lead to severe brain damage if untreated. MSUD may also present later depending on the severity of the disease. If left untreated in older individuals, during times of metabolic crisis, symptoms of the condition include uncharacteristically inappropriate, extreme, or erratic behaviour and moods, hallucinations, anorexia, weight loss, anemia, diarrhea, vomiting, dehydration, lethargy, oscillating hypertonia and hypotonia, ataxia, seizures, hypoglycemia, ketoacidosis, opisthotonus, pancreatitis, rapid neurological decline, and coma. In maple syrup urine disease, the brain concentration of branched-chain ketoacids can increase 10- to 20-fold. This leads to a depletion of glutamate and a consequent reduction in the concentration of brain glutamine, aspartate, alanine, and other amino acids. The result is a compromise of energy metabolism because of a failure of the malate-aspartate shuttle and a diminished rate of protein synthesis (PMID: 15930465). alpha-Ketoisovaleric acid is a keto-acid, which is a subclass of organic acids. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of untreated MSUD. Many affected children with organic acidemias experience intellectual disability or delayed development. Flavouring ingredient for use in butter-type flavours.

Adenylsuccinic acid

C14H18N5O11P (463.0740408)

Adenylsuccinic acid, also known as adenylosuccinate, succinyladenosine or aspartyl adenylate, belongs to the class of organic compounds known as purine ribonucleoside monophosphates. These are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. Adenylsuccinic acid is found in all living organisms, ranging from bacteria to plants to animals. Adenylsuccinic acid is an important intermediate in the de novo purine biosynthesis pathway. Specifically, adenylsuccinic acid is an intermediate in the interconversion of purine nucleotides inosine monophosphate (IMP) and adenosine monophosphate (AMP). The enzyme adenylosuccinate synthase carries out the reaction by the addition of aspartate to IMP. This reaction requires the input of energy from a phosphoanhydride bond in the form of guanosine triphosphate (GTP). Adenylsuccinic acid is a substrate least one other important metabolic reaction in purine biosynthesis. In particular, adenylsuccinic acid can be converted into fumaric acid through its interaction with the enzyme known as adenylosuccinate lyase (or adenylosuccinase). Adenylosuccinate lyase deficiency, is a rare autosomal recessive metabolic disorder characterized by the appearance of succinylaminoimidazolecarboxamide riboside (SAICA riboside) and adenylsuccinic acid in cerebrospinal fluid and urine (PMID: 8412002). Adenylosuccinate lyase deficiency presents with varying degrees of psychomotor retardation, autism, muscle wasting, and epilepsy. The exact cause of the symptoms is unknown, but possibilities include not enough purine nucleotide synthesis for cell replication, malfunctioning of the purine nucleotide cycle, and a buildup of substrates to toxic levels. Adenylsuccinic acid is a substrate of the enzyme adenylosuccinase [EC 4.3.2.2] in purine metabolism pathway. The accumulation of adenylsuccinic acid in body fluids occurs due to a deficiency of adenylosuccinase.

Nicotinic acid mononucleotide

[C11H15NO9P]+ (336.048441)

Nicotinic acid mononucleotide, also known as nicotinate ribonucleotide, belongs to the class of organic compounds known as nicotinic acid nucleotides. These are pyridine nucleotides in which the pyridine base is nicotinic acid or a derivative thereof. Nicotinic acid mononucleotide is an extremely weak basic (essentially neutral) compound (based on its pKa). Nicotinic acid mononucleotide an intermediate in the cofactor biosynthesis and the nicotinate and nicotinamide metabolism pathways. It is a substrate for nicotinamide riboside kinase, ectonucleotide pyrophosphatase/phosphodiesterase, nicotinamide mononucleotide adenylyltransferase, 5-nucleotidase, nicotinate-nucleotide pyrophosphorylase, and 5(3)-deoxyribonucleotidase. Nicotinic acid mononucleotide is an intermediate in the metabolism of Nicotinate and nicotinamide. It is a substrate for Ectonucleotide pyrophosphatase/phosphodiesterase 2, Ectonucleotide pyrophosphatase/phosphodiesterase 1, Nicotinamide mononucleotide adenylyltransferase 3, Cytosolic 5-nucleotidase IA, Cytosolic 5-nucleotidase IB, Nicotinate-nucleotide pyrophosphorylase, 5(3)-deoxyribonucleotidase (cytosolic type), Cytosolic purine 5-nucleotidase, Nicotinamide mononucleotide adenylyltransferase 2, Ectonucleotide pyrophosphatase/phosphodiesterase 3, 5-nucleotidase, 5(3)-deoxyribonucleotidase (mitochondrial) and Nicotinamide mononucleotide adenylyltransferase 1. [HMDB] NaMN is the most common mononucleotide intermediate (a hub) in NAD biogenesis. For example, in E. coli all three pyridine precursors are converted into NaMN (Table 1 and Figure 3(a)). Qa produced by the de novo Asp–DHAP pathway (genes nadB and nadA) is converted into NaMN by QAPRT (gene nadC). Salvage of both forms of niacin proceeds via NAPRT (gene pncB) either directly upon or after deamidation by NMDSE (gene pncA). Overall, more than 90\% of approximately 680 analyzed bacterial genomes contain at least one of the pathways leading to the formation of NaMN. Most of them (∼480 genomes) have the entire set of nadBAC genes for NaMN de novo synthesis from Asp that are often clustered on the chromosome and/or are co-regulated by the same transcription factors (see Section 7.08.3.1.2). Among the examples provided in Table 1, F. tularensis (Figure 4(c)) has all three genes of this de novo pathway forming a single operon-like cluster and supporting the growth of this organism in the absence of any pyridine precursors in the medium. More than half the genomes with the Asp–DHAP pathway also contain a deamidating niacin salvage pathway (genes pncAB) as do many representatives of the α-, β-, and γ-Proteobacteria, Actinobacteria, and Bacillus/Clostridium group. As already emphasized, the genomic reconstruction approach provides an assessment of the metabolic potential of an organism, which may or may not be realized under given conditions. For example, E. coli and B. subtilis can utilize both de novo and PncAB Nm salvage pathways under the same growth conditions, whereas in M. tuberculosis (having the same gene pattern) the latter pathway was considered nonfunctional, so that the entire NAD pool is generated by the de novo NadABC route. However, a recent study demonstrated the functional activity of the Nm salvage pathway in vivo, under hypoxic conditions in infected macrophages.221 This study also implicated the two downstream enzymes of NAD synthesis (NAMNAT and NADSYN) as attractive chemotherapeutic targets to treat acute and latent forms of tuberculosis. In approximately 100 species, including many Cyanobacteria (e.g., Synechococcus spp.), Bacteroidetes (e.g., Chlorobium spp.) and Proteobacteria (e.g., Caulobacter crescentus, Zymomonas mobilis, Desulfovibrio spp., and Shewanella spp. representing α-, β-, δ-, and γ-groups, respectively) the Asp–DHAP pathway is the only route to NAD biogenesis. Among them, nearly all Helicobacter spp. (except H. hepaticus), contain only the two genes nadA and nadC but lack the first gene of the pathway (nadB), which is a likely subject of nonorthologous gene replacement. One case of NadB (ASPOX) replacement by the ASPDH enzyme in T. maritima (and methanogenic archaea) was discussed in Section 7.08.2.1. However, no orthologues of the established ASPDH could be identified in Helicobacter spp. as well as in approximately 15 other diverse bacterial species that have the nadAC but lack the nadB gene (e.g., all analyzed Corynebacterium spp. except for C. diphtheriae). Therefore, the identity of the ASPOX or ASPDH enzyme in these species is still unknown, representing one of the few remaining cases of ‘locally missing genes’220 in the NAD subsystem. All other bacterial species contain either both the nadA and nadB genes (plus nadC) or none. In a limited number of bacteria (∼20 species), mostly in the two distant groups of Xanthomonadales (within γ-Proteobacteria) and Flavobacteriales (within Bacteroidetes), the Asp–DHAP pathway of Qa synthesis is replaced by the Kyn pathway. As described in Section 7.08.2.1.2, four out of five enzymes (TRDOX, KYNOX, KYNSE, and HADOX) in the bacterial version of this pathway are close homologues of the respective eukaryotic enzymes, whereas the KYNFA gene is a subject of multiple nonorthologous replacements. Although the identity of one alternative form of KYNFA (gene kynB) was established in a group of bacteria that have a partial Kyn pathway for Trp degradation to anthranilate (e.g., in P. aeruginosa or B. cereus57), none of the known KYNFA homologues are present in Xanthomonadales or Flavobacteriales. In a few species (e.g., Salinispora spp.) a complete gene set of the Kyn pathway genes co-occurs with a complete Asp–DHAP pathway. Further experiments would be required to establish to what extent and under what conditions these two pathways contribute to Qa formation. As discussed, the QAPRT enzyme is shared by both de novo pathways, and a respective gene, nadC is always found in the genomes containing one or the other pathway. Similarly, gene nadC always co-occurs with Qa de novo biosynthetic genes with one notable exception of two groups of Streptococci, S. pneumonaie and S. pyogenes. Although all other members of the Lactobacillales group also lack the Qa de novo biosynthetic machinery and rely entirely on niacin salvage, only these two human pathogens contain a nadC gene. The functional significance of this ‘out of context’ gene is unknown, but it is tempting to speculate that it may be involved in a yet-unknown pathway of Qa salvage from the human host. Among approximately 150 bacterial species that lack de novo biosynthesis genes and rely on deamidating salvage of niacin (via NAPRT), the majority (∼100) are from the group of Firmicutes. Such a functional variant (illustrated for Staphylococcus aureus in Figure 4(b)) is characteristic of many bacterial pathogens, both Gram-positive and Gram-negative (e.g., Brucella, Bordetella, and Campylobacter spp. from α-, β-, and δ-Proteobacteria, Borrelia, and Treponema spp. from Spirochaetes). Most of the genomes in this group contain both pncA and pncB genes that are often clustered on the chromosome and/or are co-regulated (see Section 7.08.3.1.2). In some cases (e.g., within Mollicutes and Spirochaetales), only the pncB, but not the pncA gene, can be reliably identified, suggesting that either of these species can utilize only the deamidated form of niacin (Na) or that some of them contain an alternative (yet-unknown) NMASE. Although the nondeamidating conversion of Nm into NMN (via NMPRT) appears to be present in approximately 50 bacterial species (mostly in β- and γ-Proteobacteria), it is hardly ever the only route of NAD biogenesis in these organisms. The only possible exception is observed in Mycoplasma genitalium and M. pneumoniae that contain the nadV gene as the only component of pyridine mononucleotide biosynthetic machinery. In some species (e.g., in Synechocystes spp.), the NMPRT–NMNAT route is committed primarily to the recycling of endogenous Nm. On the other hand, in F. tularensis (Figure 4(c)), NMPRT (gene nadV) together with NMNAT (of the nadM family) constitute the functional nondeamidating Nm salvage pathway as it supports the growth of the nadE′-mutant on Nm but not on Na (L. Sorci et al., unpublished). A similar nondeamidating Nm salvage pathway implemented by NMPRT and NMNAT (of the nadR family) is present in some (but not all) species of Pasteurellaceae in addition to (but never instead of) the RNm salvage pathway (see below), as initially demonstrated for H. ducreyi.128 A two-step conversion of NaMN into NAD via a NaAD intermediate (Route I in Figure 2) is present in the overwhelming majority of bacteria. The signature enzyme of Route I, NAMNAT of the NadD family is present in nearly all approximately 650 bacterial species that are expected to generate NaMN via de novo or salvage pathways (as illustrated by Figures 3(a) and 3(b)). All these species, without a single exception, also contain NADSYN (encoded by either a short or a long form of the nadE gene), which is required for this route. The species that lack the NadD/NadE signature represent several relatively rare functional variants, including: 1. Route I of NAD synthesis (NaMN → NaAD → NAD) variant via a bifunctional NAMNAT/NMNAT enzyme of the NadM family is common for archaea (see Section 7.08.3.2), but it appears to be present in only a handful of bacteria, such as Acinetobacter, Deinococcus, and Thermus groups. Another unusual feature of the latter two groups is the absence of the classical NADKIN, a likely subject of a nonorthologous replacement that remains to be elucidated. 2. Route II of NAD synthesis (NaMN → NMN → NAD). This route is implemented by a combination of the NMNAT of either the NadM family (as in F. tularensis) or the NadR family (as in M. succinoproducens and A. succinogenes) with NMNSYN of the NadE′ family. The case of F. tularensis described in Section 7.08.2.4 is illustrated in Figure 3(b). The rest of the NAD biosynthetic machinery in both species from the Pasteurellaceae group, beyond the shared Route II, is remarkably different from that in F. tularensis. Instead of de novo biosynthesis, they harbor a Na salvage pathway via NAPRT encoded by a pncB gene that is present in a chromosomal cluster with nadE′. Neither of these two genes are present in other Pasteurellaceae that lack the pyridine carboxylate amidation machinery (see below). 3. Salvage of RNm (RNm → NMN → NAD). A genomic signature of this pathway, a combination of the PnuC-like transporter and a bifunctional NMNAT/RNMKIN of the NadR family, is present in many Enterobacteriaceae and in several other diverse species (e.g., in M. tuberculosis). However, in H. influenzae (Figure 3(d)) and related members of Pasteurellaceae, it is the only route of NAD biogenesis. As shown in Table 1, H. influenzae as well as many other members of this group have lost nearly all components of the rich NAD biosynthetic machinery that are present in their close phylogenetic neighbors (such as E. coli and many other Enterobacteriaceae). This pathway is an ultimate route for utilization of the so called V-factors (NADP, NAD, NMN, or RNm) that are required to support growth of H. influenzae. It was established that all other V-factors are degraded to RNm by a combination of periplasmic- and membrane-associated hydrolytic enzymes.222 Although PnuC was initially considered an NMN transporter,223 its recent detailed analysis in both H. influenzae and Salmonella confirmed that its actual physiological function is in the uptake of RNm coupled with the phosphorylation of RNM to NMN by RNMKIN.17,148,224 As already mentioned, H. ducreyi and several other V-factor-independent members of the Pasteurellaceae group (H. somnus, Actinobacillus pleuropneumoniae, and Actinomycetemcomitans) harbor the NMNAT enzyme (NadV) that allows them to grow in the presence of Nm (but not Na) in the medium (Section 7.08.2.2). 4. Uptake of the intact NAD. Several groups of phylogenetically distant intracellular endosymbionts with extremely truncated genomes contain only a single enzyme, NADKIN, from the entire subsystem. Among them are all analyzed species of the Wolbachia, Rickettsia, and Blochmannia groups. These species are expected to uptake and utilize the intact NAD from their host while retaining the ability to convert it into NADP. Among all analyzed bacteria, only the group of Chlamydia does not have NADKIN and depends on the salvage of both NAD and NADP via a unique uptake system.157 A comprehensive genomic reconstruction of the metabolic potential (gene annotations and asserted pathways) across approximately 680 diverse bacterial genomes sets the stage for the accurate cross-genome projection and prediction of regulatory mechanisms that control the realization of this potential in a variety of species and growth conditions. In the next section, we summarize the recent accomplishments in the genomic reconstruction of NAD-related regulons in bacteria. Nicotinic acid mononucleotide. CAS Common Chemistry.

Pyrophosphate

H4O7P2 (177.9432294)

The anion, the salts, and the esters of pyrophosphoric acid are called pyrophosphates. The pyrophosphate anion is abbreviated PPi and is formed by the hydrolysis of ATP into AMP in cells. This hydrolysis is called pyrophosphorolysis. The pyrophosphate anion has the structure P2O74-, and is an acid anhydride of phosphate. It is unstable in aqueous solution and rapidly hydrolyzes into inorganic phosphate. Pyrophosphate is an osteotoxin (arrests bone development) and an arthritogen (promotes arthritis). It is also a metabotoxin (an endogenously produced metabolite that causes adverse health affects at chronically high levels). Chronically high levels of pyrophosphate are associated with hypophosphatasia. Hypophosphatasia (also called deficiency of alkaline phosphatase or phosphoethanolaminuria) is a rare, and sometimes fatal, metabolic bone disease. Hypophosphatasia is associated with a molecular defect in the gene encoding tissue non-specific alkaline phosphatase (TNSALP). TNSALP is an enzyme that is tethered to the outer surface of osteoblasts and chondrocytes. TNSALP hydrolyzes several substances, including inorganic pyrophosphate (PPi) and pyridoxal 5-phosphate (PLP), a major form of vitamin B6. When TSNALP is low, inorganic pyrophosphate (PPi) accumulates outside of cells and inhibits the formation of hydroxyapatite, one of the main components of bone, causing rickets in infants and children and osteomalacia (soft bones) in adults. Vitamin B6 must be dephosphorylated by TNSALP before it can cross the cell membrane. Vitamin B6 deficiency in the brain impairs synthesis of neurotransmitters which can cause seizures. In some cases, a build-up of calcium pyrophosphate dihydrate crystals in the joints can cause pseudogout.

7,8-Dihydropteroic acid

C14H14N6O3 (314.1127334)

In the mammalian host, dihydrofolate biosynthesis occurs via the reduction of folic acid, whereas in plasmodia (e.g. Plasmodium berghei, a malaria parasite) the biosynthesis of 7,8-dihydropteroate, an intermediate product in dihydrofolate synthesis, occurs via the enzymic catalysis of the reaction of 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine pyrophosphate with p-aminobenzoate. Malaria parasites synthesize their folate cofactors de novo and the antimalarial action of sulfonamides is due to their inhibiting the plasmodial dihydropteroate synthesis. The enzymes 6-hydroxymethylpterin pyrophosphokinase (EC 2.7.6.3, HPPK) and dihydropteroate synthase (EC 2.5.1.15, DHPS) catalyze sequential steps in folate biosynthesis. They are present in microorganisms but absent in mammals and therefore are especially suitable targets for antimicrobials. Sulfa drugs (sulfonamides and sulfones) currently are used as antimicrobials targeting DHPS, although resistance to these drugs is increasing. An NADPH-coupled microplate photometric assay could be used for rapid screening of chemical libraries for novel inhibitors of folate biosynthesis as the first step in developing new antimicrobial drugs targeting the folate biosynthetic pathway; in the microplate, the product of the DHPS reaction, 7,8-dihydropteroic acid, is reduced to tetrahydropteroate by excess dihydrofolate reductase (DHFR) using the cofactor NADPH (PMID: 17134675, 4354403, 3546688). 7,8-dihydropteroic acid, also known as dihydropteroinsaeure or h2pte, belongs to pterins and derivatives class of compounds.

Protoporphyrinogen IX

C34H40N4O4 (568.30494)

Protoporphyrinogen IX is an intermediate in heme biosynthesis. It is a porphyrinogen in which two pyrrole rings each have one methyl and one propionate side chain, and the other two pyrrole rings each have one methyl and one vinyl side chain. Fifteen isomers are possible but only one, type IX, occurs naturally. Protoporphyrinogen is produced by oxidative decarboxylation of coproporphyrinogen. Under certain conditions, protoporphyrinogen IX can act as a phototoxin, a neurotoxin, and a metabotoxin. A phototoxin leads to cell damage upon exposure to light. 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 porphyrins are associated with porphyrias such as porphyria variegate, acute intermittent porphyria, and hereditary coproporphyria (HCP). In particular, protoporphyrinogen IX is accumulated and excreted excessively in the feces in acute intermittent porphyria, protoporphyria, and variegate porphyria. There are several types of porphyrias (most are inherited). Hepatic porphyrias are characterized by acute neurological attacks (seizures, psychosis, extreme back and abdominal pain, and an acute polyneuropathy), while the erythropoietic forms present with skin problems (usually a light-sensitive blistering rash and increased hair growth).

Nitroglycerin

C3H5N3O9 (227.00258000000002)

Nitroglycerin is only found in individuals that have used or taken this drug. It is a volatile vasodilator which relieves angina pectoris by stimulating guanylate cyclase and lowering cytosolic calcium. [PubChem]Similar to other nitrites and organic nitrates, nitroglycerin is converted to nitric oxide (NO), an active intermediate compound which activates the enzyme guanylate cyclase. This stimulates the synthesis of cyclic guanosine 3,5-monophosphate (cGMP) which then activates a series of protein kinase-dependent phosphorylations in the smooth muscle cells, eventually resulting in the dephosphorylation of the myosin light chain of the smooth muscle fiber. The subsequent release of calcium ions results in the relaxation of the smooth muscle cells and vasodilation.

Indican

C14H17NO6 (295.1055822)

Indican is a colourless, water-soluble organic compound consisting of an indole ring conjugated to glucose. It is an indole glycoside. Its hydrolysis yields β-D-glucose and indoxyl. Indoles are compounds which consist of a pyrrole ring fused to benzene to form 2,3-benzopyrrole. The oxidation of indican by a mild oxidizing agent, e.g. atmospheric oxygen or CYP450 enzymes, yields indigo dye which is blue in colour. Indican is a substance occurring naturally in the urine of humans and mammals and also in blood plasma as a normal metabolite of tryptophan. Tryptophan is first converted to indole by gut bacteria. Following absorption from the gut, indole is converted to 3-hydroxyindole (indoxyl or indican) in the liver, where it is again then conjugated with sulfuric acid or glucoronic acid through normal xenobiotic metabolism pathways. It is then transported to the kidneys for excretion. In individuals affected by the blue diaper syndrome (a rare, autosomal recessive metabolic disorder characterized in infants by bluish urine-stained diapers), the patients exhibit a defect in tryptophan metabolism, leading to an increase in indican synthesis. Indican is then excreted into the urine and from there into the diaper where, upon exposure to air, it is converted to indigo blue dye due to oxidation by atmospheric oxygen. An increased urinary excretion of indican is seen in Hartnup disease from the bacterial degradation of unabsorbed tryptophan (PMID: 19967017). Hartnup disease is an autosomal recessive metabolic disorder affecting the absorption of nonpolar amino acids (particularly tryptophan), which leads to excessive bacterial fermentation of tryptophan (to indole) in the gut. Indican has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Its excretion is decreased by the presence of Lactobacillus bacteria in the gut (PMID: 6785555 ). Indican is an indolyl carbohydrate, a beta-D-glucoside and an exopolysaccharide. Indican is a natural product found in Indigofera suffruticosa, Isatis tinctoria, and other organisms with data available. Indican is a toxic metabolite derived from dietary proteins and tryptophan. In the intestine, proteins and tryptophan are converted to indole by tryptophanase-expressing organisms. In the liver, indole is hydroxylated to form indoxyl and indoxyl is sufated to produce indican. Overproduction of indican is associated with glomerular sclerosis, interstitial fibrosis and renal failure. Indican 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. It is a colourless organic compound, soluble in water, naturally occurring in Indigofera plants. It is a precursor of indigo dye. Indican interferes with many commercial procedures for measuring total bilirubin[6] which can be a problem for renal failure patients where blood indican levels are raised. It can cause gastrointestinal symptoms in patients where protein absorption is reduced - like Hartnups disease, allowing for greater bacterial decomposition of the Tryptophan to indole and its conversion to indican.

Demethylphylloquinone

C30H44O2 (436.3341124)

Demethylphylloquinone is a form of vitamin K that occurs in nature as part of a series of compounds with a common 2-methyl-1,4 naphthoquinone nucleus and differing isoprenoid side chains at the 3 position. Vitamin K forms comprise a single major plant form, phylloquinone with a phytyl side chain and a family of bacterially synthesized menaquinones (MKs) with multiprenyl side chains. Bacterially produced menaquinones are biologically active forms of vitamin K that are present in high concentrations in the human lower bowel. Both phylloquinone and menaquinones are bioactive in hepatic gamma-carboxylation but long-chain MKs are less well absorbed. Liver stores of vitamin K are relatively small. The hepatic reserves of phylloquinone (approximately 10\\% of the total) are labile and turn over at a faster rate than menaquinones. Vitamin K is recognised as a factor required for normal blood coagulation, and in relation to its role in bone metabolism. Vitamin K is a substrate for a liver microsomal enzyme that catalyzes the conversion of specific glutamyl residues to gamma-carboxyglutamyl residues in a limited number of proteins. These include the vitamin K-dependent clotting factors: prothrombin (factor II), factor VII, factor IX, and factor X. In the absence of vitamin K, nonfunctional clotting factors are synthesized and hemorrhage can result. Vitamin K is a coenzyme for glutamate carboxylase, which mediates the conversion of glutamate to gamma-carboxyglutamate (Gla). There are at least three Gla proteins associated with bone tissue, of which osteocalcin is the most abundant and best known. Trabecular and cortical bone appear to contain substantial concentrations of both phylloquinone and menaquinones.

The hydrogen peroxide and the hydroxytetrahydropterin can both derive from alternate routes of breakdown of a common precursor, the corresponding 4a-hydroperoxytetrahydropterin.

4-Hydroxynonenal

C9H16O2 (156.1150236)

4-Hydroxynonenal (HNE), one of the major end products of lipid peroxidation, has been shown to be involved in signal transduction and available evidence suggests that it can affect cell cycle events in a concentration-dependent manner. glutathione S-transferases (GSTs) can modulate the intracellular concentrations of HNE by affecting its generation during lipid peroxidation by reducing hydroperoxides and also by converting it into a glutathione conjugate. Overexpression of the Alpha class GSTs in cells leads to lower steady-state levels of HNE, and these cells acquire resistance to apoptosis induced by lipid peroxidation-causing agents such as H(2)O(2), UVA, superoxide anion, and pro-oxidant xenobiotics, suggesting that signaling for apoptosis by these agents is transduced through HNE. Cells with the capacity to exclude HNE from the intracellular environment at a faster rate are relatively more resistant to apoptosis caused by H(2)O(2), UVA, superoxide anion, and pro-oxidant xenobiotics as well as by HNE, suggesting that HNE may be a common denominator in mechanisms of apoptosis caused by oxidative stress. Transfection of adherent cells with HNE-metabolizing GSTs leads to transformation of these cells due to depletion of HNE. (PMID 15288119). HNE has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821).

D-Glucose

C6H12O6 (180.0633852)

Glucose is a monosaccharide containing six carbon atoms and an aldehyde group. It is referred to as an aldohexose. The glucose molecule can exist in an open-chain (acyclic) and ring (cyclic) form, the latter being the result of an intramolecular reaction between the aldehyde C atom and the C-5 hydroxyl group to form an intramolecular hemiacetal. In aqueous solution, both forms are in equilibrium and at pH 7 the cyclic one is predominant. Glucose is a primary source of energy for all living organisms. It is a fundamental metabolite found in all organisms, ranging from bacteria to plants to humans. Most of the world’s glucose is made by plants and algae during photosynthesis from water and carbon dioxide, where it is used to make cellulose (and other polymeric forms of glucose called polysaccharides) that stabilize plant cell walls. Glucose is also found in fruits and other parts of plants in its free state. In animals, glucose can be generated from the breakdown of glycogen in a process known as glycogenolysis. Glucose can also be synthesized de novo in animals. In particular it can be synthesized in the liver and kidneys from non-carbohydrate intermediates, such as pyruvate and glycerol, by a process known as gluconeogenesis. Humans also consume large amounts of glucose as part of their regular diet. Ingested glucose initially binds to the receptor for sweet taste on the tongue in humans. This complex of the proteins T1R2 and T1R3 makes it possible to identify glucose-containing food sources. Glucose in the body mainly comes from food - about 300 g per day for the average adult. In humans, the breakdown of glucose-containing polysaccharides happens partly during chewing by means of the enzyme known as amylase, which is contained in saliva, as well as by other enzymes such as maltase, lactase and sucrase on the brush border of the small intestine. The blood sugar content of a healthy person in the short-time fasting state, e.g. after overnight fasting, is about 70 to 100 mg/dL of blood (4 to 5.5 mM). In blood plasma, the measured values are about 10–15\\\\% higher. Dysregulated metabolism of glucose can lead to a number of diseases including diabetes. Diabetes is a metabolic disorder where the body is unable to regulate levels of glucose in the blood either because of a lack of insulin in the body or the failure, by cells in the body, to respond properly to insulin. Each of these situations can be caused by persistently high elevations of blood glucose levels, through pancreatic burnout and insulin resistance. A glucoside is a glycoside that is derived from glucose. Glucosides are common in plants, but rare in animals. Glucose is produced when a glucoside is hydrolysed by purely chemical means, or decomposed by fermentation or enzymes.

7-Methylxanthine

C6H6N4O2 (166.0490736)

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

Menatetrenone

C31H40O2 (444.302814)

Menatetrenone, also known as MK-4, is a vitamin K compound used as a hemostatic agent, and also as adjunctive therapy for the pain of osteoporosis. Menatetrenone is one of the nine forms of vitamin K2 and is a short-chain menaquinone. MK-4 is produced via conversion of vitamin K1 in the body, in the testes, pancreas and arterial walls (Wikipedia). Vitamin K2 is found in brassicas. Vitamin K2 is widely distributed in green leaves and vegetables. It is a fat-soluble dietary factor effective in controlling blood coagulation. All members of the vitamin K group of vitamins share a methylated naphthoquinone ring structure and vary in the aliphatic side chain attached at the 3-position. Phylloquinone (also known as vitamin K1) invariably contains in its side chain four isoprenoid residues, one of which is unsaturated. Human milk contains between 1 and 4 micrograms/litre of vitamin K1, while formula-derived milk can contain up to 100 micrograms/litre in supplemented formulas. Vitamin K2 concentrations in human milk appear to be much lower than those of vitamin K1. It is estimated that there is a 0.25 to 1.7 percent occurrence of vitamin K deficiency bleeding in the first week of the infants life with a prevalence of 2-10 cases per 100,000 births. The biochemistry of how vitamin K is used to convert glutamic acid (Glu) to gamma-carboxyglutamic acid (Gla) has been elucidated over the past thirty years in academic laboratories throughout the world. Within the cell, vitamin K undergoes electron reduction to a reduced form of vitamin K (called vitamin K hydroquinone) by the enzyme vitamin K epoxide reductase (or VKOR). Another enzyme then oxidizes vitamin K hydroquinone to allow carboxylation of Glu to Gla; this enzyme is called the gamma-glutamyl carboxylase or the vitamin K-dependent carboxylase. The carboxylation reaction will only proceed if the carboxylase enzyme is able to oxidize vitamin K hydroquinone to vitamin K epoxide at the same time. The carboxylation and epoxidation reactions are said to be coupled reactions. Vitamin K epoxide is then re-converted into vitamin K by the vitamin K epoxide reductase. These two enzymes comprise the so-called vitamin K cycle. Vitamin K2 is one of the reasons why vitamin K is rarely deficient in a human diet (vitamin K is continually recycled in our cells). Vitamin K1 is also known as phylloquinone or phytomenadione (also called phytonadione). Vitamin K2 (menaquinone, menatetrenone) is normally produced by bacteria in the large intestine, and dietary deficiency is extremely rare unless the intestines are heavily damaged or are unable to absorb the molecule, or due to decreased production by normal flora, as seen in broad spectrum antibiotic use. Menaquinone-4 is a menaquinone whose side-chain contains 4 isoprene units in an all-trans-configuration. It has a role as a bone density conservation agent, a human metabolite, an antioxidant, an anti-inflammatory agent and a neuroprotective agent. Menatetrenone has been used in trials studying the treatment of Diabetes, Osteoporosis, Prediabetic State, and Hepatocellular Carcinoma. Menatetrenone is a menaquinone compound and form of vitamin K2 with potential antineoplastic activity. Menatetrenone may act by modulating the signalling of certain tyrosine kinases, thereby affecting several transcription factors including c-myc and c-fos. This agent inhibits tumor cell growth by inducing apoptosis and cell cycle arrest.

Biopterin

C9H11N5O3 (237.0861856)

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.

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].

CoQ is found in the membranes of endoplasmic reticulum, peroxisomes, lysosomes, vesicles and notably the inner membrane of the mitochondrion where it is an important part of the electron transport chain; there it passes reducing equivalents to acceptors such as Coenzyme Q : cytochrome c - oxidoreductase. CoQ is also essential in the formation of the apoptosome along with other adapter proteins. The loss of trophic factors activates pro-apoptotic enzymes, causing the breakdown of mitochondria. Because of its ability to transfer electrons and therefore act as an antioxidant, Coenzyme Q has become a valued dietary supplement. CoQ10 has been widely used for the treatment of heart disease (especially heart failure), gum diseases, and also breast cancer. The benzoquinone portion of Coenzyme Q10 is synthesized from amino acids, while the isoprene sidechain is synthesized from acetyl CoA through the mevalonate pathway. The mevalonate pathway is used for the first steps of cholesterol biosynthesis. A compound composed of the standard 2,3-dimethoxy-5-methylbenzoquinone nucleus common to ubiquinones; and a side chain of a single isoprenoid unit.

4-Trimethylammoniobutanoic acid

C7H15NO2 (145.110273)

4-Trimethylammoniobutanoic acid, also known as gamma-butyrobetaine (GBB) or 3-dehydroxycarnitine, is a highly water-soluble derivative of gamma-aminobutyric acid (GABA). It is also a precursor of L-carnitine. It is a substrate of gamma butyrobetaine hydroxylase/dioxygenase (also known as BBOX) which catalyzes the formation of L-carnitine from gamma-butyrobetaine, the last step in the L-carnitine biosynthesis pathway. Carnitine is essential for the transport of activated fatty acids across the mitochondrial membrane during mitochondrial beta-oxidation. Numerous disorders have been described that lead to disturbances in energy production and in intermediary metabolism which are characterized by the production and excretion of unusual acylcarnitines. A mutation in the gene coding for carnitine-acylcarnitine translocase, or the OCTN2 transporter aetiologically, causes a carnitine deficiency that results in poor intestinal absorption of dietary L-carnitine, impaired reabsorption by the kidney, and increased urinary loss. Determination of the qualitative pattern of acylcarnitines can be of diagnostic and therapeutic importance. The betaine structure of carnitine requires special analytical procedures for recording. The ionic nature of L-carnitine causes a high water solubility which decreases with increasing chain length of the ester group in the acylcarnitines. Therefore, the distribution of L-carnitine and acylcarnitines in various organs is defined by their function and their physicochemical properties as well. High-performance liquid chromatography (HPLC) permits screening for free and total carnitine, as well as complete quantitative acylcarnitine determination, including the long-chain acylcarnitine profile (PMID: 17508264, Monatshefte fuer Chemie (2005), 136(8), 1279-1291., Int J Mass Spectrom. 1999;188:39-52.). 3-Dehydroxycarnitine is an acylcarnitine.

S-Adenosylmethionine

C15H23N6O5S+ (399.1450568)

S-adenosylmethionine, also known as sam or adomet, is a member of the class of compounds known as 5-deoxy-5-thionucleosides. 5-deoxy-5-thionucleosides are 5-deoxyribonucleosides in which the ribose is thio-substituted at the 5position by a S-alkyl group. S-adenosylmethionine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). S-adenosylmethionine can be found in a number of food items such as common grape, half-highbush blueberry, jerusalem artichoke, and thistle, which makes S-adenosylmethionine a potential biomarker for the consumption of these food products. S-adenosylmethionine can be found primarily in blood, cerebrospinal fluid (CSF), feces, and urine, as well as throughout most human tissues. S-adenosylmethionine exists in all eukaryotes, ranging from yeast to humans. In humans, S-adenosylmethionine is involved in several metabolic pathways, some of which include phosphatidylcholine biosynthesis PC(22:1(13Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)), phosphatidylcholine biosynthesis PC(22:0/18:3(9Z,12Z,15Z)), phosphatidylcholine biosynthesis PC(24:0/24:0), and phosphatidylcholine biosynthesis PC(20:5(5Z,8Z,11Z,14Z,17Z)/20:0). S-adenosylmethionine is also involved in several metabolic disorders, some of which include methylenetetrahydrofolate reductase deficiency (MTHFRD), 3-phosphoglycerate dehydrogenase deficiency, monoamine oxidase-a deficiency (MAO-A), and aromatic l-aminoacid decarboxylase deficiency. Moreover, S-adenosylmethionine is found to be associated with diabetes mellitus type 2 and neurodegenerative disease. S-adenosylmethionine is a non-carcinogenic (not listed by IARC) potentially toxic compound. S-Adenosyl methionine is a common cosubstrate involved in methyl group transfers, transsulfuration, and aminopropylation. Although these anabolic reactions occur throughout the body, most SAM-e is produced and consumed in the liver. More than 40 methyl transfers from SAM-e are known, to various substrates such as nucleic acids, proteins, lipids and secondary metabolites. It is made from adenosine triphosphate (ATP) and methionine by methionine adenosyltransferase (EC 2.5.1.6). SAM was first discovered by Giulio Cantoni in 1952 . Significant first-pass metabolism in the liver. Approximately 50\\\% of S-Adenosylmethionine (SAMe) is metabolized in the liver. SAMe is metabolized to S-adenosylhomocysteine, which is then metabolized to homocysteine. Homocysteine can either be metabolized to cystathionine and then cysteine or to methionine. The cofactor in the metabolism of homocysteine to cysteine is vitamin B6. Cofactors for the metabolism of homocysteine to methionine are folic acid, vitamin B12 and betaine (T3DB). S-Adenosylmethionine (CAS: 29908-03-0), also known as SAM or AdoMet, is a physiologic methyl radical donor involved in enzymatic transmethylation reactions and present in all living organisms. It possesses anti-inflammatory activity and has been used in the treatment of chronic liver disease (From Merck, 11th ed). S-Adenosylmethionine is a natural substance present in the cells of the body. It plays a crucial biochemical role by donating a one-carbon methyl group in a process called transmethylation. S-Adenosylmethionine, formed from the reaction of L-methionine and adenosine triphosphate catalyzed by the enzyme S-adenosylmethionine synthetase, is the methyl-group donor in the biosynthesis of both DNA and RNA nucleic acids, phospholipids, proteins, epinephrine, melatonin, creatine, and other molecules.

5-Methoxytryptophol

C11H13NO2 (191.09462380000002)

5-Methoxytryptophol is synthesized by the pineal gland. Daily rhythms in pineal methoxyindole metabolism have been described in rodents and humans (5-Methoxytryptophol levels are coincident with serotonin levels in rodents pineal) and 5-Methoxytryptophol at its highest during the daylight hours and fall markedly soon after the onset of darkness, coincident with increases in the levels of pineal melatonin and the activities of pineal serotonin-N-acetyltransferase (EC 2.3.1.87, SNAT) and hydroxyindole-O-methyltransferase (EC 2.1.1.4, HIOMT). The fact that the levels of 5-methoxytryptophol and melatonin vary in parallel suggests that the major factor generating the methoxyindole rhythms is not SNAT activity, but perhaps a change in the availability (for metabolism) of "stored" serotonin. When the onset of darkness is delayed by 12 hours, human 5-methoxytryptophol (and melatonin) rhythms usually require 3 or 4 days to adjust to the new lighting regimen. Environmental factors, other than light, that activate the sympathetic nervous system or cause epinephrine to be secreted from the adrenal medulla (e.g., the stress of immobilization; insulin-induced hypoglycemia) can override the inhibitory effects of light and accelerate melatonin synthesis. Rhythms in 5-methoxytryptophol (and melatonin) synthesis apparently persist among animals placed in environments of continuous darkness; the source of the cyclic signal (mediated by the pineal sympathetic nerves) has not yet been identified. Preliminary evidence suggests that levels of a peptide hormone, arginine vasotocin, in rat pineal and sera also exhibit daily rhythms and are increased by norepinephrine. The circadian rhythm of melatonin secretion is generated in the suprachiasmatic nucleus. Sleep disruption, nightly restlessness, sundowning, and other circadian disturbances are frequently seen in Alzheimers disease patients. Changes in the suprachiasmatic nucleus and pineal gland are thought to be the biological basis for these behavioral disturbances.

Glycerophosphocholine

C8H20NO6P (257.102819)

Glycerophosphorylcholine (GPC) is a choline derivative and one of the two major forms of choline storage (along with phosphocholine) in the cytosol. Glycerophosphorylcholine is also one of the four major organic osmolytes in renal medullary cells, changing their intracellular osmolyte concentration in parallel with extracellular tonicity during cellular osmoadaptation. As an osmolyte, Glycerophosphorylcholine counteracts the effects of urea on enzymes and other macromolecules. Kidneys (especially medullar cells), which are exposed under normal physiological conditions to widely fluctuating extracellular solute concentrations, respond to hypertonic stress by accumulating the organic osmolytes glycerophosphorylcholine (GPC), betaine, myo-inositol, sorbitol and free amino acids. Increased intracellular contents of these osmolytes are achieved by a combination of increased uptake (myo-inositol and betaine) and synthesis (sorbitol, GPC), decreased degradation (GPC) and reduced osmolyte release. GPC is formed in the breakdown of phosphatidylcholine (PtC). This pathway is active in many body tissues, including mammary tissue. Choline alfoscerate, also known as glycerophosphocholine or choline glycerophosphate, is a member of the class of compounds known as glycerophosphocholines. Glycerophosphocholines are lipids containing a glycerol moiety carrying a phosphocholine at the 3-position. Choline alfoscerate is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Choline alfoscerate can be found in a number of food items such as radish, strawberry guava, yellow pond-lily, and pepper (c. baccatum), which makes choline alfoscerate a potential biomarker for the consumption of these food products. L-Alpha glycerylphosphorylcholine (alpha-GPC, choline alfoscerate) is a natural choline compound found in the brain.

Temurin

C9H12N4O3 (224.0909362)

Temurin is a methyl derivative of uric acid, found occasionally in human urine. Temurin is one of the purine components in urinary calculi. Methylated purines originate from the metabolism of methylxanthines (caffeine, theophylline and theobromine). Methyluric acids are indistinguishable from uric acid by simple methods routinely used in clinical laboratories, requiring the use of high-performance liquid chromatography (HPLC). Purine derivatives in urinary calculi could be considered markers of abnormal purine metabolism. The content of a purine derivative in stone depends on its average urinary excretion in the general population, similarity to the chemical structure of uric acid, and content of the latter in stone. This suggests that purines in stones represent a solid solution with uric acid as solvent. It is also plausible that methylxanthines, ubiquitous components of the diet and drugs, are involved in the pathogenesis of urolithiasis. (PMID: 11712316, 15833286, 3506820, 15013152).

L-Thyronine

C15H15NO4 (273.100103)

Thyronine (T0) is a de-iodinated form of thyroxine. Thyronine are a group of metabolites derived from thyroxine and triiodothyronine via the peripheral enzymatic removal of iodines from the thyroxine nucleus. Thyronine is the thyroxine nucleus devoid of its four iodine atoms. Thyronine (T0) has been identified in human urine. In 22 normal individuals urinary thyronine concentrations were found to range between 8-25 nmol‚ÅÑ24h (PMID: 479355). Thyronine is thought to be a byproduct of thyroxine metabolism and arises through the action of thyroxine deiodinases. Iodide is actively absorbed from the bloodstream and concentrated in the thyroid follicles. (If there is a deficiency of dietary iodine, the thyroid enlarges in an attempt to trap more iodine, resulting in goitre.) Via a reaction with the enzyme thyroperoxidase, iodine is covalently bound to tyrosine residues in the thyroglobulin molecules, forming monoiodotyrosine (MIT) and diiodotyrosine (DIT). Linking two moieties of DIT produces thyroxine. Combining one particle of MIT and one particle of DIT produces triiodothyronine.

Glycoursodeoxycholic acid

C26H43NO5 (449.31410680000005)

Glycoursodeoxycholic acid is an acyl glycine and a bile acid-glycine conjugate. It is a secondary bile acid produced by the action of enzymes existing in the microbial flora of the colonic environment. In hepatocytes, both primary and secondary bile acids undergo amino acid conjugation at the C-24 carboxylic acid on the side chain, and almost all bile acids in the bile duct therefore exist in a glycine conjugated form (PMID: 16949895). Bile acids are steroid acids found predominantly in the bile of mammals. The distinction between different bile acids is minute, depending only on the presence or absence of hydroxyl groups on positions 3, 7, and 12. Bile acids are physiological detergents that facilitate excretion, absorption, and transport of fats and sterols in the intestine and liver. Bile acids are also steroidal amphipathic molecules derived from the catabolism of cholesterol. They modulate bile flow and lipid secretion, are essential for the absorption of dietary fats and vitamins, and have been implicated in the regulation of all the key enzymes involved in cholesterol homeostasis. Bile acids recirculate through the liver, bile ducts, small intestine and portal vein to form an enterohepatic circuit. They exist as anions at physiological pH and, consequently, require a carrier for transport across the membranes of the enterohepatic tissues. The unique detergent properties of bile acids are essential for the digestion and intestinal absorption of hydrophobic nutrients. Bile acids have potent toxic properties (e.g. membrane disruption) and there are a plethora of mechanisms to limit their accumulation in blood and tissues (PMID: 11316487, 16037564, 12576301, 11907135).

Indigo

C16H10N2O2 (262.074224)

Indigo (indigo dye or indigotin) is an organic compound with a distinctive blue color. It is an oxindole dimer consisting of two fused oxindole rings. Indoles are compounds which consist of a pyrrole ring fused to benzene to form 2,3-benzopyrrole. Indigo is found in both plants and animals and has been detected in human urine and human tissues (PMID: 11076521; PMID: 8667928). The natural precursor to indigo is indican, a colorless, water-soluble derivative of the amino acid tryptophan. Indican readily hydrolyzes to release β-D-glucose and indoxyl. Oxidation of indoxyl by CYP450 enzymes in the liver or kidneys can convert indoxyl to indigo (PMID: 11076521). Likewise, exposure to air can convert indoxyl to indigo. In addition to the mammalian production of minute amounts of indigo, this chemical can also be recovered in far larger amounts from plants. Historically, indigo has been extracted from the leaves of certain plants of the Indigofera genus, in particular Indigofera tinctoria. Indigofera plants were commonly grown and used throughout the world for the production of indigo dyestuff. This was economically important due to the previous rarity of some blue dyestuffs historically. India was the primary supplier of indigo to Europe as early as the Greco-Roman era. The association of India with indigo is reflected in the Greek word for the dye, indikón. The Romans latinized the term to indicum, which passed into Italian dialect and eventually into English as the word indigo. Most indigo dye produced today is synthetic, constituting several thousand tons each year. It is most commonly associated with the production of denim cloth and blue jeans.

(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.

Urocanic acid

C6H6N2O2 (138.0429256)

An alpha,beta-unsaturated monocarboxylic acid that is prop-2-enoic acid substituted by a 1H-imidazol-4-yl group at position 3. It is a metabolite of hidtidine. Urocanic acid is an intermediate in the catabolism of L-histidine.; Urocanic is a breakdown (deamination) product of histidine. In the liver, urocanic acid is an intermediate in the conversion of histidine to glutamic acid, whereas in the epidermis, it accumulates and may be both a UV protectant and an immunoregulator. Urocanic acid (UA) exists as a trans isomer (t-UA, approximately 30 mg/cm2) in the uppermost layer of the skin (stratum corneum). t-UA is formed as the cells of the second layer of skin become metabolically inactive. During this process, proteins and membranes degrade, histidine is released, and histidase (histidine ammonia lyase) catalyzes the deamination of histidine to form t-UA. t-UA accumulates in the epidermis until removal by either the monthly skin renewal cycle or sweat. Upon absorption of UV light, the naturally occurring t-UA isomerizes to its cis form, c-UA. Because DNA lesions (e.g., pyrimidine dimers) in the lower epidermis can result from UV-B absorption, initial research proposed that t-UA acted as a natural sunscreen absorbing UV-B in the stratum corneum before the damaging rays could penetrate into lower epidermal zones. Researchers have found that c-UA also suppresses contact hypersensitivity and delayed hypersensitivity, reduces the Langerhans cell count in the epidermis, prolongs skin-graft survival time, and affects natural killer cell activity.

L-Glutamine

C5H10N2O3 (146.069139)

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.

Methionine

C5H11NO2S (149.0510466)

A sulfur-containing amino acid that is butyric acid bearing an amino substituent at position 2 and a methylthio substituent at position 4. Methionine (symbol Met or M)[3] (⫽mɪˈθaɪəniːn⫽)[4] is an essential amino acid in humans. As the precursor of other non-essential amino acids such as cysteine and taurine, versatile compounds such as SAM-e, and the important antioxidant glutathione, methionine plays a critical role in the metabolism and health of many species, including humans. Methionine is also involved in angiogenesis and various processes related to DNA transcription, epigenetic expression, and gene regulation. Methionine was first isolated in 1921 by John Howard Mueller.[5] It is encoded by the codon AUG. It was named by Satoru Odake in 1925, as an abbreviation of its structural description 2-amino-4-(methylthio)butanoic acid. L-Methionine is the L-isomer of Methionine, an essential amino acid for human development. Methionine acts as a hepatoprotectant.

It has been isolated from the plants belonging to genus Colchicum. Colchicine appears as odorless or nearly odorless pale yellow needles or powder that darkens on exposure to light. Used to treat gouty arthritis, pseudogout, sarcoidal arthritis and calcific tendinitis. (EPA, 1998) (S)-colchicine is a colchicine that has (S)-configuration. It is a secondary metabolite, has anti-inflammatory properties and is used to treat gout, crystal-induced joint inflammation, familial Mediterranean fever, and many other conditions. It has a role as a mutagen, an anti-inflammatory agent and a gout suppressant. It is a colchicine and an alkaloid. It is an enantiomer of a (R)-colchicine. Colchicine is an Alkaloid. Colchicine is a plant alkaloid that is widely used for treatment of gout. Colchicine has not been associated with acute liver injury or liver test abnormalities except with serious overdoses. Colchicine is a natural product found in Colchicum arenarium, Colchicum bivonae, and other organisms with data available. Colchicine is an alkaloid isolated from Colchicum autumnale with anti-gout and anti-inflammatory activities. The exact mechanism of action by which colchicines exerts its effect has not been completely established. Colchicine binds to tubulin, thereby interfering with the polymerization of tubulin, interrupting microtubule dynamics, and disrupting mitosis. This leads to an inhibition of migration of leukocytes and other inflammatory cells, thereby reducing the inflammatory response to deposited urate crystals. Colchicine may also interrupt the cycle of monosodium urate crystal deposition in joint tissues, thereby also preventing the resultant inflammatory response. Overall, colchicine decreases leukocyte chemotaxis/migration and phagocytosis to inflamed areas, and inhibits the formation and release of a chemotactic glycoprotein that is produced during phagocytosis of urate crystals. A major alkaloid from Colchicum autumnale L. and found also in other Colchicum species. Its primary therapeutic use is in the treatment of gout, but it has been used also in the therapy of familial Mediterranean fever (PERIODIC DISEASE). See also: Colchicine; probenecid (component of).

Histidine (symbol His or H)[2] is an essential 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), a carboxylic acid group (which is in the deprotonated –COO− form under biological conditions), and an imidazole side chain (which is partially protonated), classifying it as a positively charged amino acid at physiological pH. Initially thought essential only for infants, it has now been shown in longer-term studies to be essential for adults also.[3] It is encoded by the codons CAU and CAC. Histidine was first isolated by Albrecht Kossel and Sven Gustaf Hedin in 1896.[4] The name stems from its discovery in tissue, from ἱστός histós "tissue".[2] It is also a precursor to histamine, a vital inflammatory agent in immune responses.
