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

Carnitine
(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.

Sucrose
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.

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.

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

Deoxycholic Acid is a steroidal acid that is a secondary bile acid, with cytolytic activity. Upon subcutaneous administration, deoxycholic acid causes lysis of adipocytes and improves the appearance of fullness associated with submental fat. Also, it may potentially be able to reduce fat in other subcutaneous fatty tissues. Deoxycholic acid, naturally produced by the metabolism of cholic acid by intestinal bacteria, is involved in the emulsification of dietary fats in the intestine. Deoxycholic acid is a bile acid formed by bacterial action from cholate. It is usually conjugated with glycine or taurine. Deoxycholic acid acts as a detergent to solubilize fats for intestinal absorption, is reabsorbed itself, and is used as a choleretic and detergent. 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, deoxycholic acid can act as a hepatotoxin, a metabotoxin, and an oncometabolite. 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. An oncometabolite is a compound, when present at chronically high levels, that promotes tumour growth and survival. 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. High bile acid levels lead to the generation of reactive oxygen species and reactive nitrogen species, disruption of the cell membrane and mitochondria, induction of DNA damage, mutation and apoptosis, and the development of reduced apoptosis capability upon chronic exposure (PMID: 24884764). Chronically high levels of deoxycholic acid are associated with familial hypercholanemia. In hypercholanemia, bile acids, including deoxycholic 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. Chronically high levels of deoxycholic acid are also associated with several forms of cancer including colon cancer, pancreatic cancer, esophageal cancer, and many other GI cancers.

Gentisate
Gentisic acid, also known as gentisate or 2,5-dioxybenzoate, 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. Gentisic acid is also classified as a dihydroxybenzoic acid. It is a derivative of benzoic acid and a minor (1\\\\\%) product of the metabolic break down of aspirin, which is excreted by the kidneys. Gentisic acid is found in essentially all organisms ranging from bacteria to fungi to plants to animals. Gentisic acid has been associated with a number of useful effects on human health and exhibits anti-inflammatory, antigenotoxic, hepatoprotective, neuroprotective, antimicrobial, and especially antioxidant activities (PMID: 31825145). It is widely distributed in plants as a secondary plant product such as Gentiana spp., Citrus spp., Vitis vinifera, Pterocarpus santalinus, Helianthus tuberosus, Hibiscus rosa-sinensis, Olea europaea, and Sesamum indicum and in fruits such as avocados, batoko plum, kiwi fruits, apple, bitter melon, black berries, pears, and some mushrooms (PMID: 31825145). Gentisic acid is found in higher concentrations in a number of foods such as tarragons, common thymes, and common sages and in a lower concentration in grape wines, rosemaries, and sweet marjorams. Gentisic acid has also been shown to act as a pathogen-inducible signal for the activation of plant defenses in tomato plants and cucumbers (PMID: 16321412; https://doi.org/10.1094/MPMI.1999.12.3.227). Gentisic acid is a dihydroxybenzoic acid. It is a crystalline powder that forms monoclinic prism in water solution. Gentisic acid is an active metabolite of salicylic acid degradation. There is an increasing amount of evidence indicating that gentisic acid has a broad spectrum of biological activity, such as anti-inflammatory, antirheumatic and antioxidant properties. Gentisic acid is also a byproduct of tyrosine and benzoate metabolism. [HMDB]. Gentisic acid is found in many foods, some of which are common sage, common grape, nutmeg, and dill. 2,5-dihydroxybenzoic acid is a dihydroxybenzoic acid having the two hydroxy groups at the 2- and 5-positions. It has a role as a MALDI matrix material, an EC 1.13.11.33 (arachidonate 15-lipoxygenase) inhibitor, a human metabolite, a fungal metabolite and a mouse metabolite. It is functionally related to a benzoic acid.

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

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

Vitamin The parent compound of the 6-aminopurines, composed of a purine having an amino group at C-6. Adenine (/ˈædɪnɪn/) (symbol A or Ade) is a purine nucleobase. It is one of the four nucleobases in the nucleic acids of DNA, the other three being guanine (G), cytosine (C), and thymine (T). Adenine derivatives have various roles in biochemistry including cellular respiration, in the form of both the energy-rich adenosine triphosphate (ATP) and the cofactors nicotinamide adenine dinucleotide (NAD), flavin adenine dinucleotide (FAD) and Coenzyme A. It also has functions in protein synthesis and as a chemical component of DNA and RNA.[2] The shape of adenine is complementary to either thymine in DNA or uracil in RNA. The adjacent image shows pure adenine, as an independent molecule. When connected into DNA, a covalent bond is formed between deoxyribose sugar and the bottom left nitrogen (thereby removing the existing hydrogen atom). The remaining structure is called an adenine residue, as part of a larger molecule. Adenosine is adenine reacted with ribose, as used in RNA and ATP; Deoxyadenosine is adenine attached to deoxyribose, as used to form DNA. Adenine forms several tautomers, compounds that can be rapidly interconverted and are often considered equivalent. However, in isolated conditions, i.e. in an inert gas matrix and in the gas phase, mainly the 9H-adenine tautomer is found.[3][4] Purine metabolism involves the formation of adenine and guanine. Both adenine and guanine are derived from the nucleotide inosine monophosphate (IMP), which in turn is synthesized from a pre-existing ribose phosphate through a complex pathway using atoms from the amino acids glycine, glutamine, and aspartic acid, as well as the coenzyme tetrahydrofolate. Adenine (6-Aminopurine), a purine, is one of the four nucleobases in the nucleic acid of DNA. Adenine acts as a chemical component of DNA and RNA. Adenine also plays an important role in biochemistry involved in cellular respiration, the form of both ATP and the cofactors (NAD and FAD), and protein synthesis[1][2][3].

L-Tryptophan
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 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.

Cholic acid
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.

It is a conjugate acid of an azelaate(2-) and an azelaate. Azelaic acid is a saturated dicarboxylic acid found naturally in wheat, rye, and barley. It is also produced by Malassezia furfur, also known as Pityrosporum ovale, which is a species of fungus that is normally found on human skin. Azelaic acid is effective against a number of skin conditions, such as mild to moderate acne, when applied topically in a cream formulation of 20\\\\\%. It works in part by stopping the growth of skin bacteria that cause acne, and by keeping skin pores clear. Azelaic acids antimicrobial action may be attributable to inhibition of microbial cellular protein synthesis. Azelaic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). The physiologic effect of azelaic acid is by means of Decreased Protein Synthesis, and Decreased Sebaceous Gland Activity. Azelaic Acid is a naturally occurring dicarboxylic acid produced by Malassezia furfur and found in whole grain cereals, rye, barley and animal products. Azelaic acid possesses antibacterial, keratolytic, comedolytic, and anti-oxidant activity. Azelaic acid is bactericidal against Proprionibacterium acnes and Staphylococcus epidermidis due to its inhibitory effect on the synthesis of microbial cellular proteins. Azelaic acid exerts its keratolytic and comedolytic effects by reducing the thickness of the stratum corneum and decreasing the number of keratohyalin granules by reducing the amount and distribution of filaggrin in epidermal layers. Azelaic acid also possesses a direct anti-inflammatory effect due to its scavenger activity of free oxygen radical. This drug is used topically to reduce inflammation associated with acne and rosacea. Azelaic acid is a saturated dicarboxylic acid found naturally in wheat, rye, and barley.

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

It is a conjugate acid of a salicylate. It is a colorless solid, it is a precursor to and a metabolite of aspirin (acetylsalicylic acid). It is a plant hormone. The name is from Latin salix for willow tree. It is an ingredient in some anti-acne products. Salts and esters of salicylic acid are known as salicylates. Salicylic acid modulates COX1 enzymatic activity to decrease the formation of pro-inflammatory prostaglandins. Salicylate may competitively inhibit prostaglandin formation. Salicylates antirheumatic (nonsteroidal anti-inflammatory) actions are a result of its analgesic and anti-inflammatory mechanisms. Salicylic acid works by causing the cells of the epidermis to slough off more readily, preventing pores from clogging up, and allowing room for new cell growth. Salicylic acid inhibits the oxidation of uridine-5-diphosphoglucose (UDPG) competitively with nicotinamide adenosine dinucleotide and noncompetitively with UDPG. It also competitively inhibits the transferring of glucuronyl group of uridine-5-phosphoglucuronic acid to the phenolic acceptor. The wound-healing retardation action of salicylates is probably due mainly to its inhibitory action on mucopolysaccharide synthesis. Salicylic acid is biosynthesized from the amino acid phenylalanine. In Arabidopsis thaliana, it can be synthesized via a phenylalanine-independent pathway.

5-Hydroxytryptophan
5-hydroxytryptophan is a tryptophan derivative that is tryptophan substituted by a hydroxy group at position 5. It has a role as a human metabolite and a neurotransmitter. 5-Hydroxytryptophan, DL- is a racemic mixture of 5-hydroxytryptophan (5-HTP), a precursor to the neurotransmitter serotonin with anti-depressant, analgesic and appetite-suppressant activities. DL-5-HTP is decarboxylated to serotonin by aromatic-L-amino-acid decarboxylase, and results in increased serotonin levels within the brain. Mediated through serotonin receptors, elevated levels of serotonin causes increased serotonin neurotransmissions, hence leading to release of depression, pain and appetite. 5-Hydroxy-L-tryptophan is an aromatic amino acid naturally produced by the body from the essential amino acid l-tryptophan. 5-Hydroxy-L-tryptophan is the immediate precursor of the neurotransmitter serotonin. The conversion to serotonin is catalyzed by the enzyme aromatic l-amino acid decarboxylase (EC 4.1.1.28, AADC1 also known as dopa decarboxylase), an essential enzyme in the metabolism of the monoamine neurotransmitters. An accumulation of 5-Hydroxy-L-tryptophan in cerebrospinal fluid occurs in Aromatic l-amino acid decarboxylase deficiency (OMIM 608643), accompanied by an increased excretion in the urine of the patients, which are indicative of the disorder but not specific 5-Hydroxy-L-tryptophan is also increased in other disorders such as in Parkinsons patients with severe postural instability and gait disorders. Confirmation of the diagnosis AADC deficiency is then required by enzyme activity measurement or genetic analysis. The amount of endogenous 5-Hydroxy-L-tryptophan available for serotonin synthesis depends on the availability of tryptophan and on the activity of various enzymes, especially tryptophan hydroxylase (EC 1.14.16.4), indoleamine 2,3-dioxygenase (EC 1.13.11.52), and tryptophan 2,3-dioxygenase. (EC 1.13.11.11, TDO). 5-Hydroxy-L-tryptophan has been used clinically for over 30 years. In addition to depression, the therapeutic administration of 5-Hydroxy-L-tryptophan has been shown to be effective in treating a wide variety of conditions, including fibromyalgia, insomnia, binge eating associated with obesity, cerebellar ataxia, and chronic headaches. 5-Hydroxy-L-tryptophan easily crosses the blood-brain barrier and effectively increases central nervous system (CNS) synthesis of serotonin. Supplementation with 5-Hydroxy-L-tryptophan is hypothesized to normalize serotonin synthesis, which is putatively related to its antidepressant properties. (A3384, A3385, A3386).

Citric acid
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.

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

It has a role as a human metabolite and a mouse metabolite. It is a bile acid, a dihydroxy-5beta-cholanic acid and a C24-steroid. It is a conjugate acid of a chenodeoxycholate. Chenodeoxycholic acid (or Chenodiol) is an epimer of ursodeoxycholic acid (DB01586). Chenodeoxycholic acid is a bile acid naturally found in the body. It works by dissolving the cholesterol that makes gallstones and inhibiting production of cholesterol in the liver and absorption in the intestines, which helps to decrease the formation of gallstones. It can also reduce the amount of other bile acids that can be harmful to liver cells when levels are elevated. Chenodeoxycholic acid (chenodiol) is a primary bile acid, synthesized in the liver and present in high concentrations in bile that is used therapeutically to dissolve cholesterol gallstones. Chronic therapy is associated with transient elevations in serum aminotransferase levels in up to 30\\\\\% of patients, but chenodiol has been linked to only rare instances of clinically apparent liver injury with jaundice. Chenodeoxycholic acid is a natural product found in Ganoderma lucidum and Homo sapiens with data available. A bile acid, usually conjugated with either glycine or taurine. It acts as a detergent to solubilize fats for intestinal absorption and is reabsorbed by the small intestine. It is used as cholagogue, a choleretic laxative, and to prevent or dissolve gallstones. Chenodeoxycholic acid is a bile acid. 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).

Fumaric acid
Fumaric acid appears as a colorless crystalline solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Combustible, though may be difficult to ignite. Used to make paints and plastics, in food processing and preservation, and for other uses. Fumaric acid is a butenedioic acid in which the C=C double bond has E geometry. It is an intermediate metabolite in the citric acid cycle. It has a role as a food acidity regulator, a fundamental metabolite and a geroprotector. It is a conjugate acid of a fumarate(1-). Fumaric acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Fumaric acid is a precursor to L-malate in the Krebs tricarboxylic acid cycle. It is formed by the oxidation of succinate by succinate dehydrogenase. Fumarate is converted by fumarase to malate. A fumarate is a salt or ester of the organic compound fumaric acid, a dicarboxylic acid. Fumarate has recently been recognized as an oncometabolite. (A15199). As a food additive, fumaric acid is used to impart a tart taste to processed foods. It is also used as an antifungal agent in boxed foods such as cake mixes and flours, as well as tortillas. Fumaric acid is also added to bread to increase the porosity of the final baked product. It is used to impart a sour taste to sourdough and rye bread. In cake mixes, it is used to maintain a low pH and prevent clumping of the flours used in the mix. In fruit drinks, fumaric acid is used to maintain a low pH which, in turn, helps to stabilize flavor and color. Fumaric acid also prevents the growth of E. coli in beverages when used in combination with sodium benzoate. When added to wines, fumaric acid helps to prevent further fermentation and yet maintain low pH and eliminate traces of metallic elements. In this fashion, it helps to stabilize the taste of wine. Fumaric acid can also be added to dairy products, sports drinks, jams, jellies and candies. Fumaric acid helps to break down bonds between gluten proteins in wheat and helps to create a more pliable dough. Fumaric acid is used in paper sizing, printer toner, and polyester resin for making molded walls. Fumaric acid is a dicarboxylic acid. It is a precursor to L-malate in the Krebs tricarboxylic acid (TCA) cycle. It is formed by the oxidation of succinic acid by succinate dehydrogenase. Fumarate is converted by the enzyme fumarase to malate. Fumaric acid has recently been identified as an oncometabolite or an endogenous, cancer causing metabolite. High levels of this organic acid can be found in tumors or biofluids surrounding tumors. Its oncogenic action appears to due to its ability to inhibit prolyl hydroxylase-containing enzymes. In many tumours, oxygen availability becomes limited (hypoxia) very quickly due to rapid cell proliferation and limited blood vessel growth. The major regulator of the response to hypoxia is the HIF transcription factor (HIF-alpha). Under normal oxygen levels, protein levels of HIF-alpha are very low due to constant degradation, mediated by a series of post-translational modification events catalyzed by the prolyl hydroxylase domain-containing enzymes PHD1, 2 and 3, (also known as EglN2, 1 and 3) that hydroxylate HIF-alpha and lead to its degradation. All three of the PHD enzymes are inhibited by fumarate. Fumaric acid is found to be associated with fumarase deficiency, which is an inborn error of metabolism. It is also a metabolite of Aspergillus. Produced industrially by fermentation of Rhizopus nigricans, or manufactured by catalytic or thermal isomerisation of maleic anhydride or maleic acid. Used as an antioxidant, acidulant, leavening agent and flavouring agent in foods. Present in raw lean fish. Dietary supplement. Used in powdered products since fumaric acid is less hygroscopic than other acids. A precursor to L-malate in the Krebs tricarboxylic acid cycle. It is formed by the oxidation of succinate by succinate dehydrogenase (wikipedia). Fumaric acid is also found in garden tomato, papaya, wild celery, and star fruit. Fumaric acid.

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).

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
L-Phenylalanine
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.

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. 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 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.

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.

Succinic acid
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.

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

L-Dopa
L-dopa is an optically active form of dopa having L-configuration. Used to treat the stiffness, tremors, spasms, and poor muscle control of Parkinsons disease It has a role as a prodrug, a hapten, a neurotoxin, an antiparkinson drug, a dopaminergic agent, an antidyskinesia agent, an allelochemical, a plant growth retardant, a human metabolite, a mouse metabolite and a plant metabolite. It is a dopa, a L-tyrosine derivative and a non-proteinogenic L-alpha-amino acid. It is a conjugate acid of a L-dopa(1-). It is an enantiomer of a D-dopa. It is a tautomer of a L-dopa zwitterion. Levodopa is a prodrug of dopamine that is administered to patients with Parkinsons due to its ability to cross the blood-brain barrier. Levodopa can be metabolised to dopamine on either side of the blood-brain barrier and so it is generally administered with a dopa decarboxylase inhibitor like carbidopa to prevent metabolism until after it has crossed the blood-brain barrier. Once past the blood-brain barrier, levodopa is metabolized to dopamine and supplements the low endogenous levels of dopamine to treat symptoms of Parkinsons. The first developed drug product that was approved by the FDA was a levodopa and carbidopa combined product called Sinemet that was approved on May 2, 1975. 3,4-Dihydroxy-L-phenylalanine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Levodopa is an Aromatic Amino Acid. Levodopa is an amino acid precursor of dopamine with antiparkinsonian properties. Levodopa is a prodrug that is converted to dopamine by DOPA decarboxylase and can cross the blood-brain barrier. When in the brain, levodopa is decarboxylated to dopamine and stimulates the dopaminergic receptors, thereby compensating for the depleted supply of endogenous dopamine seen in Parkinsons disease. To assure that adequate concentrations of levodopa reach the central nervous system, it is administered with carbidopa, a decarboxylase inhibitor that does not cross the blood-brain barrier, thereby diminishing the decarboxylation and inactivation of levodopa in peripheral tissues and increasing the delivery of dopamine to the CNS. L-Dopa is used for the treatment of Parkinsonian disorders and Dopa-Responsive Dystonia and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system. Peripheral tissue conversion may be the mechanism of the adverse effects of levodopa. It is standard clinical practice to co-administer a peripheral DOPA decarboxylase inhibitor - carbidopa or benserazide - and often a catechol-O-methyl transferase (COMT) inhibitor, to prevent synthesis of dopamine in peripheral tissue.The naturally occurring form of dihydroxyphenylalanine and the immediate precursor of dopamine. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to dopamine. It is used for the treatment of parkinsonian disorders and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system. [PubChem]L-Dopa is the naturally occurring form of dihydroxyphenylalanine and the immediate precursor of dopamine. Unlike dopamine itself, L-Dopa can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to dopamine. In particular, it is metabolized to dopamine by aromatic L-amino acid decarboxylase. Pyridoxal phosphate (vitamin B6) is a required cofactor for this decarboxylation, and may be administered along with levodopa, usually as pyridoxine. The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside ... L-DOPA, also known as levodopa or 3,4-dihydroxyphenylalanine 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). L-DOPA is found naturally in both animals and plants. It is made via biosynthesis from the amino acid L-tyrosine by the enzyme tyrosine hydroxylase.. L-DOPA is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), which are collectively known as catecholamines. The Swedish scientist Arvid Carlsson first showed in the 1950s that administering L-DOPA to animals with drug-induced (reserpine) Parkinsonian symptoms caused a reduction in the intensity of the animals symptoms. Unlike dopamine itself, L-DOPA can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to dopamine. In particular, it is metabolized to dopamine by aromatic L-amino acid decarboxylase. Pyridoxal phosphate (vitamin B6) is a required cofactor for this decarboxylation, and may be administered along with levodopa, usually as pyridoxine. As a result, L-DOPA is a drug that is now used for the treatment of Parkinsonian disorders and DOPA-Responsive Dystonia. It is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system. It is standard clinical practice in treating Parkinsonism to co-administer a peripheral DOPA decarboxylase inhibitor - carbidopa or benserazide - and often a catechol-O-methyl transferase (COMT) inhibitor, to prevent synthesis of dopamine in peripheral tissue. Side effects of L-DOPA treatment may include: hypertension, arrhythmias, nausea, gastrointestinal bleeding, disturbed respiration, hair loss, disorientation and confusion. L-DOPA can act as an L-tyrosine mimetic and be incorporated into proteins by mammalian cells in place of L-tyrosine, generating protease-resistant and aggregate-prone proteins in vitro and may contribute to neurotoxicity with chronic L-DOPA administration. L-phenylalanine, L-tyrosine, and L-DOPA are all precursors to the biological pigment melanin. The enzyme tyrosinase catalyzes the oxidation of L-DOPA to the reactive intermediate dopaquinone, which reacts further, eventually leading to melanin oligomers.

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

Tetrahydrobiopterin
Tetrahydrobiopterin (CAS: 17528-72-2), also known as BH4, is an essential cofactor in the synthesis of neurotransmitters and nitric oxide (PMID: 16946131). In fact, it is used by all three human nitric-oxide synthases (NOS) eNOS, nNOS, and iNOS as well as the enzyme glyceryl-ether monooxygenase. It is also essential in the conversion of phenylalanine into tyrosine by the enzyme phenylalanine-4-hydroxylase; the conversion of tyrosine into L-dopa by the enzyme tyrosine hydroxylase; and the conversion of tryptophan into 5-hydroxytryptophan via tryptophan hydroxylase. Specifically, tetrahydrobiopterin is a cofactor for tryptophan 5-hydroxylase 1, tyrosine 3-monooxygenase, and phenylalanine hydroxylase, all of which are essential for the formation of the neurotransmitters dopamine, noradrenaline, and adrenaline. Tetrahydrobiopterin has been proposed to be involved in the promotion of neurotransmitter release in the brain and the regulation of human melanogenesis. A defect in BH4 production and/or a defect in the enzyme dihydropteridine reductase (DHPR) causes phenylketonuria type IV, as well as dopa-responsive dystonias. BH4 is also implicated in Parkinsons disease, Alzheimers disease, and depression. Tetrahydrobiopterin is present in probably every cell or tissue of higher animals.

It is the substrate of a group of enzymes acyl-Coenzyme A oxidases 1, 2, 3 (E.C.: 1.3.3.6) corresponding to palmitoyl, branched chain, and pristanoyl, respectively, in the peroxisomal fatty acid beta-oxidation, producing hydrogen peroxide. Abnormality of this group of enzymes is linked to coma, dehydration, diabetes, fatty liver, hyperinsulinemia, hyperlipidemia, and leukodystrophy. It is also a substrate of a group of enzymes called acyl-Coenzyme A dehydrogenase (E.C.:1.3.99-, including 1.3.99.2, 1.3.99.3) in the metabolism of fatty acids or branched chain amino acids in the mitochondria (Rozen et al., 1994). Acyl-Coenzyme A dehydrogenase (1.3.99.3) has shown to contribute to kidney-associated diseases, such as adrenogential syndrome, kidney failure, kidney tubular necrosis, homocystinuria, as well as other diseases including cretinism, encephalopathy, hypoglycemia, medium chain acyl-CoA dehydrogenase deficiency. The gene (ACADS) also plays a role in theta oscillation during sleep. In addition, crotonoyl-CoA is the substrate of enoyl coenzyme A hydratase (E.C.4.2.1.17) in the mitochondria during lysine degradation and tryptophan metabolism, benzoate degradation via CoA ligation; in contrast it is the product of this enzyme in the butanoate metabolism. Moreover, it is produced from multiple enzymes in the butanoate metabolism pathway, including 3-Hydroxybutyryl-CoA dehydratase (E.C.:4.2.1.55), glutaconyl-CoA decarboxylase (E.C.: 4.1.1.70), vinylacetyl-CoA Δ-isomerase (E.C.: 5.3.3.3), and trans-2-enoyl-CoA reductase (NAD+) (E.C.: 1.3.1.44). In lysine degradation and tryptophan metabolism, crotonoyl CoA is produced by glutaryl-Coenzyme A dehydrogenase (E.C.:1.3.99.7) lysine and tryptophan metabolic pathway. This enzyme is linked to type-1glutaric aciduria, metabolic diseases, movement disorders, myelinopathy, and nervous system diseases.

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

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

Muramic acid
Muramic acid is an amino sugar acid. In terms of chemical composition, it is the ether of lactic acid and glucosamine. It occurs naturally as N-acetylmuramic acid in peptidoglycan, whose primary function is a structural component of many typical bacterial cell walls. Muramic acid, also known as muramate or murexide, belongs to the class of organic compounds known as sugar acids and derivatives.

Pyridoxamine 5'-phosphate
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.

Sulfadoxine
Sulfadoxine is only found in individuals that have used or taken this drug. It is a long acting sulfonamide that is used, usually in combination with other drugs, for respiratory, urinary tract, and malarial infections. [PubChem]Sulfadoxine is a sulfa drug, often used in combination with pyrimethamine to treat malaria. This medicine may also be used to prevent malaria in people who are living in, or will be traveling to, an area where there is a chance of getting malaria. Sulfadoxine targets Plasmodium dihydropteroate synthase and dihydrofolate reductase. Sulfa drugs or Sulfonamides are antimetabolites. They compete with para-aminobenzoic acid (PABA) for incorporation into folic acid. The action of sulfonamides exploits the difference between mammal cells and other kinds of cells in their folic acid metabolism. All cells require folic acid for growth. Folic acid (as a vitamin) diffuses or is transported into human cells. However, folic acid cannot cross bacterial (and certain protozoan) cell walls by diffusion or active transport. For this reason bacteria must synthesize folic acid from p-aminobenzoic acid.

Furazolidone
Furazolidone is a nitrofuran derivative with antiprotozoal and antibacterial activity. Furazolidone has been shown to exhibit antibiotic and anti-microbial functions (PMID 1476092, 6651278). Furazolidone is also used as a poultry food additive. It is marketed by Roberts Laboratories under the brand name Furoxone and by GlaxoSmithKline as Dependal-M. Furoxone has a broad antibacterial spectrum covering the majority of gastrointestinal tract pathogens including E. coli, staphylococci, Salmonella, Shigella, Proteus, Aerobacter aerogenes, Vibrio cholerae and Giardia lamblia. Its bactericidal activity is based upon its interference with DNA replication and protein production. Furazolidone binds bacterial DNA which leads to the gradual inhibition of monoamine oxidase (From Martindale, The Extra Pharmacopoeia, 30th ed, p514). Furazolidone and its related free radical products are believed to bind DNA and induce cross-links. Bacterial DNA is particularly susceptible to this drug leading to high levels of mutations (transitions and transversions) in the bacterial chromosome. Furazolidone belongs to the family of Nitrofurans. These are compounds containing a furan ring which bears a nitro group.

Tridemorph
Systemic eradicant cereal fungicide Tridemorph is a fungicide. It was developed in the 1960s by the German multinational BASF who sell tridemorph under the trade name Calixin. It is used to control the fungus Erysiphe graminis in cereals, Mycosphaerella species in bananas, and Caticum solmonicolor in tea. Tridemorph is applied onto many crops across the world, but very little data on usage and production is in the public domain. In high doses it has been shown to have teratogenic effects. These effect are manifested in edemas, hemorrhages, hematomas, abnormal development of the brain (hydrocephalia), visceral cranium (micrognathia, cleft palate) and genitourinary system (hydronephrosis), in decreased size of pelvic bones, shoulder girdle, front and hind limbs, etc. (PMID 7324433
N-Acetyltryptophan
N-Acetyl-L-tryptophan or N-Acetyltryptophan, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetyltryptophan can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetyltryptophan is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-tryptophan. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\\\% of all human proteins and 68\\\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetyltryptophan can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free tryptophan can also occur. Many N-acetylamino acids, including N-acetyltryptophan are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). N-Acetyltryptophan has also been used as a protein stabilizer. It prevents protein molecules from oxidative degradation by scavenging oxygen dissolved in protein solutions (PMID: 21903216 ). N-Acetyltryptophan has been identified as a catabolite of tryptophan generated by the gut microbiota. After absorption through the intestinal epithelium, tryptophan catabolites enter the bloodstream and are later excreted in the urine (PMID: 28916042). N-Acetyltryptophan is an inhibitor of cytochrome c release and an antagonist of the neurokinin 1 receptor (NK-1R). These inhibitory effects are thought have a useful role in neuroprotection. For instance, in mouse models of amyotrophic lateral sclerosis (ALS) the administration of N-Acetyltryptophan has been shown delay disease onset, extend survival, and ameliorate deterioration in motor performance ALS transgenic mice (PMID: 25986728). N-acetyltryptophan has been shown to significantly reduce blood-brain barrier permeability and improve functional outcome in rat models of traumatic brain injury (PMID: 29256408). N-Acetyltryptophan has also been shown to have a role in preventing hepatic ischemia-reperfusion injury. This is thought to occur through de-activation of the RIP2/caspase/IL-1beta signaling pathway (PMID: 31184936).

Estrone
Estrone is a major mammalian estrogen. The conversion of the natural C19 steroids, testosterone and androstenedione into estrone is dependent on a complex key reaction catalyzed by the cytochrome P450 aromatase (EC 1.14.14.1, unspecific monooxygenase), which is expressed in many tissues of the adult human (e.g. ovary, fat tissue), but not in the liver. The ovaries after menopause continue to produce androstenedione and testosterone in significant amounts and these androgens are converted in fat, muscle, and skin into estrone. When women between the ages of 45 and 64 years have prophylactic oophorectomy (when hysterectomy is performed for benign disease to prevent the development of ovarian cancer), evidence suggests that oophorectomy increases the subsequent risk of coronary heart disease (CHD) and osteoporosis. Whereas 14,000 women die of ovarian cancer every year nearly 490,000 women die of heart disease and 48,000 women die within 1 year after hip fracture. Therefore, the decision to perform prophylactic oophorectomy should be approached with great caution for the majority of women who are at low risk of developing ovarian cancer. Steroid sulfatase (EC 3.1.6.2, STS) hydrolyzes steroid sulfates, such as estrone sulfate to estrone which can be converted to steroids with potent estrogenic properties, that is, estradiol; STS activity is much higher in breast tumors and high levels of STS mRNA expression in tumors are associated with a poor prognosis. The biological roles of estrogens in tumorigenesis are certainly different between the endometrium and breast, although both are considered "estrogen-dependent tissues". 17beta-hydroxysteroid dehydrogenases (EC 1.1.1.62, 17-HSDs) are enzymes involved in the formation of active sex steroids. estrone is interconverted by two enzymes 17-HSD types. Type 1 converts estrone to estradiol and Type 2 catalyzes the reverse reaction. (PMID: 17653961, 17513923, 17470679, 17464097).

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

4-Hydroxyphenylpyruvic acid
3-(4-hydroxy-phenyl)pyruvic acid, also known as 4-hydroxy a-oxobenzenepropanoate or 3-(p-hydroxyphenyl)-2-oxopropanoate, belongs to phenylpyruvic acid derivatives class of compounds. Those are compounds containing a phenylpyruvic acid moiety, which consists of a phenyl group substituted at the second position by an pyruvic acid. 3-(4-hydroxy-phenyl)pyruvic acid is slightly soluble (in water) and a moderately acidic compound (based on its pKa). 3-(4-hydroxy-phenyl)pyruvic acid can be synthesized from pyruvic acid. 3-(4-hydroxy-phenyl)pyruvic acid can also be synthesized into 4-hydroxyphenylpyruvic acid oxime. 3-(4-hydroxy-phenyl)pyruvic acid can be found in a number of food items such as garden onion (variety), rose hip, sourdough, and horseradish tree, which makes 3-(4-hydroxy-phenyl)pyruvic acid a potential biomarker for the consumption of these food products. 3-(4-hydroxy-phenyl)pyruvic acid can be found primarily in blood and urine, as well as in human prostate tissue. 3-(4-hydroxy-phenyl)pyruvic acid exists in all eukaryotes, ranging from yeast to humans. In humans, 3-(4-hydroxy-phenyl)pyruvic acid is involved in few metabolic pathways, which include disulfiram action pathway, phenylalanine and tyrosine metabolism, and tyrosine metabolism. 3-(4-hydroxy-phenyl)pyruvic acid is also involved in several metabolic disorders, some of which include tyrosinemia type I, phenylketonuria, tyrosinemia, transient, of the newborn, and alkaptonuria. Moreover, 3-(4-hydroxy-phenyl)pyruvic acid is found to be associated with hawkinsinuria and phenylketonuria. 4-Hydroxyphenylpyruvic acid (4-HPPA) is a keto acid that is involved in the tyrosine catabolism pathway. It is a product of the enzyme (R)-4-hydroxyphenyllactate dehydrogenase (EC 1.1.1.222) and is formed during tyrosine metabolism. The conversion from tyrosine to 4-HPPA is catalyzed by tyrosine aminotransferase. Additionally, 4-HPPA can be converted to homogentisic acid which is one of the precursors to ochronotic pigment. The enzyme 4-hydroxyphenylpyruvic acid dioxygenase (HPD) catalyzes the reaction that converts 4-hydroxyphenylpyruvic acid to homogentisic acid. A deficiency in the catalytic activity of HPD is known to lead to tyrosinemia type III, an autosomal recessive disorder characterized by elevated levels of blood tyrosine and massive excretion of tyrosine derivatives into urine. It has been shown that hawkinsinuria, an autosomal dominant disorder characterized by the excretion of hawkinsin, may also be a result of HPD deficiency (PMID: 11073718). Moreover, 4-hydroxyphenylpyruvic acid is also found to be associated in phenylketonuria, which is also an inborn error of metabolism. There are two isomers of HPPA, specifically 4HPPA and 3HPPA, of which 4HPPA is the most common. 4-HPPA has been found to be a microbial metabolite in Escherichia (ECMDB).

DL-Malic acid
Malic acid (CAS: 6915-15-7) is a tart-tasting organic dicarboxylic acid that plays a role in many sour or tart foods. Apples contain malic acid, which contributes to the sourness of a green apple. Malic acid can make a wine taste tart, although the amount decreases with increasing fruit ripeness (Wikipedia). In its ionized form, malic acid is called malate. Malate is an intermediate of the TCA cycle along with fumarate. It can also be formed from pyruvate as one of the anaplerotic reactions. In humans, malic acid is both derived from food sources and synthesized in the body through the citric acid cycle or Krebs cycle which takes place in the mitochondria. Malates importance to the production of energy in the body during both aerobic and anaerobic conditions is well established. Under aerobic conditions, the oxidation of malate to oxaloacetate provides reducing equivalents to the mitochondria through the malate-aspartate redox shuttle. During anaerobic conditions, where a buildup of excess reducing equivalents inhibits glycolysis, malic acids simultaneous reduction to succinate and oxidation to oxaloacetate is capable of removing the accumulating reducing equivalents. This allows malic acid to reverse hypoxias inhibition of glycolysis and energy production. In studies on rats, it has been found that only tissue malate is depleted following exhaustive physical activity. Other key metabolites from the citric acid cycle needed for energy production were found to be unchanged. Because of this, a deficiency of malic acid has been hypothesized to be a major cause of physical exhaustion. Notably, the administration of malic acid to rats has been shown to elevate mitochondrial malate and increase mitochondrial respiration and energy production. Malic acid has been found to be a metabolite in Aspergillus (Hugo Vanden Bossche, D.W.R. Mackenzie and G. Cauwenbergh. Aspergillus and Aspergillosis, 1987).

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

Perillic acid
Perillic acid, also known as perillate, belongs to the class of organic compounds known as menthane monoterpenoids. These are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. Perillic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Perillic acid is an intermediate in the Limonene and pinene degradation pathway. (KEGG); Its measurement in urine is used to monitor cancer patients receiving oral Limonene (a farnesyl transferase inhibitor that has shown antitumor properties)(PubMed ID 8723738 ). Perillic acid is found in cardamom. C471 - Enzyme Inhibitor > C2020 - Farnesyl Transferase Inhibitor

Adenosine phosphosulfate
Adenosine phosphosulfate, also known as adenylylsulfate or adenosine sulfatophosphate, 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. Adenosine phosphosulfate exists in all living species, ranging from bacteria to humans. Within humans, adenosine phosphosulfate participates in a number of enzymatic reactions. In particular, adenosine phosphosulfate can be biosynthesized from sulfate through the action of the enzyme bifunctional 3-phosphoadenosine 5-phosphosulfate synthase 2. In addition, adenosine phosphosulfate can be converted into phosphoadenosine phosphosulfate; which is catalyzed by the enzyme bifunctional 3-phosphoadenosine 5-phosphosulfate synthase 2. In humans, adenosine phosphosulfate is involved in sulfate/sulfite metabolism. Outside of the human body, Adenosine phosphosulfate has been detected, but not quantified in several different foods, such as chia, yardlong beans, swiss chards, sapodilla, and chicory leaves. This could make adenosine phosphosulfate a potential biomarker for the consumption of these foods. An adenosine 5-phosphate having a sulfo group attached to one the phosphate OH groups. Adenosine phosphosulfate (also known as APS) is the initial compound formed by the action of ATP sulfurylase (or PAPS synthetase) on sulfate ions after sulfate uptake. PAPS synthetase 1 is a bifunctional enzyme with both ATP sulfurylase and APS kinase activity, which mediates two steps in the sulfate activation pathway. The first step is the transfer of a sulfate group to ATP to yield adenosine 5-phosphosulfate (APS), and the second step is the transfer of a phosphate group from ATP to APS yielding 3-phosphoadenylylsulfate (PAPS). In mammals, PAPS is the sole source of sulfate; APS appears to be only an intermediate in the sulfate-activation pathway. [HMDB]. Adenosine phosphosulfate is found in many foods, some of which are muskmelon, garlic, caraway, and peach (variety).
Nicotinamide adenine dinucleotide phosphate
NADPH is the reduced form of NADP+, and NADP+ is the oxidized form of NADPH. Nicotinamide adenine dinucleotide phosphate (NADP) is a coenzyme composed of ribosylnicotinamide 5-phosphate (NMN) coupled with a pyrophosphate linkage to 5-phosphate adenosine 2,5-bisphosphate. NADP serves as an electron carrier in a number of reactions, being alternately oxidized (NADP+) and reduced (NADPH). NADP is formed through the addition of a phosphate group to the 2 position of the adenosyl nucleotide through an ester linkage (Dorland, 27th ed). This extra phosphate is added by the enzyme NAD+ kinase and removed via NADP+ phosphatase. NADP is also known as TPN (triphosphopyridine nucleotide) and it is an important cofactor used in anabolic reactions in all forms of cellular life. Examples include the Calvin cycle, cholesterol synthesis, fatty acid elongation, and nucleic acid synthesis (Wikipedia). Nicotinamide adenine dinucleotide phosphate.

1,4-Dithiothreitol
Dithiothreitol (DTT) is the common name for a small-molecule redox reagent known as Clelands reagent. DTTs formula is C4H10O2S2 and the molecular structure of its reduced form is shown at the right; its oxidized form is a disulfide-bonded 6-membered ring (shown below). Its name derives from the four-carbon sugar, threose. DTT has an epimeric (sister) compound, dithioerythritol. A common use of DTT is as a reducing or "deprotecting" agent for thiolated DNA. The terminal sulfur atoms of thiolated DNA have a tendency to form dimers in solution, especially in the presence of oxygen. Dimerization greatly lowers the efficiency of subsequent coupling reactions such as DNA immobilization on gold in biosensors. Typically DTT is mixed with a DNA solution and allowed to react, and then is removed by filtration (for the solid catalyst) or by chromatography (for the liquid form). The DTT removal procedure is often called "desalting.". DTT is frequently used to reduce the disulfide bonds of proteins and, more generally, to prevent intramolecular and intermolecular disulfide bonds from forming between cysteine residues of proteins. However, even DTT cannot reduce buried (solvent-inaccessible) disulfide bonds, so reduction of disulfide bonds is sometimes carried out under denaturing conditions (e.g., at high temperatures, or in the presence of a strong denaturant such as 6 M guanidinium hydrochloride, 8 M urea, or 1\\% sodium dodecylsulfate). Conversely, the solvent exposure of different disulfide bonds can be assayed by their rate of reduction in the presence of DTT. DTT can also be used as an oxidizing agent. Its principal advantage is that effectively no mixed-disulfide species are populated, in contrast to other agents such as glutathione. In very rare cases, a DTT adduct may be formed, i.e., the two sulfur atoms of DTT may form disulfide bonds to different sulfur atoms; in such cases, DTT cannot cyclize since it has no remaining free thiols. Due to air oxidation, DTT is a relatively unstable compound whose useful life can be extended by refrigeration and handling in an inert atmosphere. Since protonated sulfurs have lowered nucleophilicities, DTT becomes less potent as the pH lowers. Tris(2-carboxyethyl)phosphine HCl (TCEP hydrochloride) is an alternative which is more stable and works even at low pH. Dithiothreitol (DTT) is the common name for a small-molecule redox reagent known as Clelands reagent. DTT has an epimeric compound, dithioerythritol.

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
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.

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

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

Guanosine diphosphate mannose
Guanosine diphosphate mannose, also known as gdp-D-mannose or guanosine pyrophosphoric acid mannose, is a member of the class of compounds known as purine nucleotide sugars. Purine nucleotide sugars are purine nucleotides bound to a saccharide derivative through the terminal phosphate group. Guanosine diphosphate mannose is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Guanosine diphosphate mannose can be found in a number of food items such as sorrel, common persimmon, citrus, and butternut, which makes guanosine diphosphate mannose a potential biomarker for the consumption of these food products. Guanosine diphosphate mannose exists in all living species, ranging from bacteria to humans. In humans, guanosine diphosphate mannose is involved in a couple of metabolic pathways, which include fructose and mannose degradation and fructose intolerance, hereditary. Guanosine diphosphate mannose is also involved in fructosuria, which is a metabolic disorder. Guanosine diphosphate mannose or GDP-mannose is a nucleotide sugar that is a substrate for glycosyltransferase reactions in metabolism. This compound is a substrate for enzymes called mannosyltransferases . GDP-mannose is a nucleoside diphosphate sugar that is important in the production of fucosylated oligosaccharides. In particular, GDP-mannose is converted to GDP-fucose, which is the fucose donor in the construction of all mammalian fucosylated glycans. GDP-mannose is transformed to GDP-fucose via three enzymatic reactions carried out by two proteins, GDP-mannose 4,6-dehydratase (GMD) and a second enzyme, GDP-keto-6-deoxymannose 3,5-epimerase, 4-reductase. GDP-mannose 4,6-dehydratase (EC 4.2.1.47) catalyzes the chemical reaction: GDP-mannose <--> GDP-4-dehydro-6-deoxy-D-mannose + H2O. The epimerase converts the GDP-4-dehydro-6-deoxy-D-mannose to GDP-fucose (PMID: 12651883). GDP-mannose is also synthesized from mannose 1-phosphate via the enzyme ATP-mannose-1-phosphate-guanyltransferase and GTP.

Aciclovir
Aciclovir is only found in individuals that have used or taken this drug. It is a guanosine analog that acts as an antimetabolite. Viruses are especially susceptible. Used especially against herpes. [PubChem]Viral (HSV-1, HSV-2 and VZV) thymidine kinase converts aciclovir to the aciclovir monophosphate, which is then converted to the diphosphate by cellular guanylate kinase, and finally to the triphosphate by phosphoglycerate kinase, phosphoenolpyruvate carboxykinase, and pyruvate kinase. Aciclovir triphosphate competitively inhibits viral DNA polymerase and competes with the natural deoxyguanosine triphosphate, for incorporation into viral DNA. Once incorporated, aciclovir triphosphate inhibits DNA synthesis by acting as a chain terminator.

Eugenol
Eugenol appears as clear colorless pale yellow or amber-colored liquid. Odor of cloves. Spicy pungent taste. (NTP, 1992) Eugenol is a phenylpropanoid formally derived from guaiacol with an allyl chain substituted para to the hydroxy group. It is a major component of clove essential oil, and exhibits antibacterial, analgesic and antioxidant properties. It has been widely used in dentistry to treat toothache and pulpitis. It has a role as an allergen, a human blood serum metabolite, a sensitiser, a volatile oil component, a flavouring agent, an EC 1.4.3.4 (monoamine oxidase) inhibitor, a radical scavenger, an antibacterial agent, an antineoplastic agent, an apoptosis inducer, an anaesthetic, an analgesic, a voltage-gated sodium channel blocker, a NF-kappaB inhibitor and an anti-inflammatory agent. It is a phenylpropanoid, a monomethoxybenzene, a member of phenols and an alkenylbenzene. It is functionally related to a guaiacol. Eugenol is a naturally occurring phenolic molecule found in several plants such as cinnamon, clove, and bay leaves. It has been used as a topical antiseptic as a counter-irritant and in dental preparations with zinc oxide for root canal sealing and pain control. Although not currently available in any FDA-approved products (including OTC), eugenol has been found to have anti-inflammatory, neuroprotective, antipyretic, antioxidant, antifungal and analgesic properties. Its exact mechanism of action is unknown, however, it has been shown to interfere with action potential conduction. There are a number of unapproved OTC products available containing eugenol that advertise its use for the treatment of toothache. Eugenol is a Standardized Chemical Allergen. The physiologic effect of eugenol is by means of Increased Histamine Release, and Cell-mediated Immunity. Eugenol, also called clove oil, is an aromatic oil extracted from cloves that is used widely as a flavoring for foods and teas and as an herbal oil used topically to treat toothache and more rarely to be taken orally to treat gastrointestinal and respiratory complaints. Eugenol in therapeutic doses has not been implicated in causing serum enzyme elevations or clinically apparent liver injury, but ingestions of high doses, as with an overdose, can cause severe liver injury. Eugenol is a natural product found in Dahlia sherffii, Elettaria cardamomum, and other organisms with data available. Eugenol is an allyl chain-substituted guaiacol, i.e. 2-methoxy-4-(2-propenyl)phenol. Eugenol is a member of the allylbenzene class of chemical compounds. It is a clear to pale yellow oily liquid extracted from certain essential oils especially from clove oil, nutmeg, cinnamon, and bay leaf.

Deoxycorticosterone
11-Deoxycorticosterone (also called desoxycortone, 21-hydroxyprogesterone, DOC, or simply deoxycorticosterone) is a steroid hormone produced by the adrenal gland that possesses mineralocorticoid activity and acts as a precursor to aldosterone. It is classified as a member of the 21-hydroxysteroids. 21-hydroxysteroids are steroids carrying a hydroxyl group at the 21-position of the steroid backbone. Deoxycorticosterone is very hydrophobic, practically insoluble (in water), and relatively neutral. Deoxycorticosterone can be synthesized from progesterone by 21-beta-hydroxylase and is then converted to corticosterone by 11-beta-hydroxylase. Corticosterone is then converted to aldosterone by aldosterone synthase. Deoxycorticosterone stimulates the collecting tubules in the kidney to continue to excrete potassium in much the same way that aldosterone does. Deoxycorticosterone has about 1/20 of the sodium retaining power of aldosterone and about 1/5 the potassium excreting power of aldosterone (Wikipedia). Deoxycorticosterone can be found throughout all human tissues and has been detected in amniotic fluid and blood. When present in sufficiently high levels, deoxycorticosterone can act as a hypertensive agent and a metabotoxin. A hypertensive agent increases blood pressure and causes the production of more urine. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of deoxycorticosterone are associated with congenital adrenal hyperplasia (CAH) and with adrenal tumors producing deoxycorticosterone (PMID: 20671982). High levels of this mineralocorticoid are associated with resistant hypertension, which can result in polyuria, polydipsia, increased blood volume, edema, and cardiac enlargement. Deoxycorticosterone can be used to treat adrenal insufficiency. In particular, desoxycorticosterone acetate (DOCA) is used as replacement therapy in Addisons disease. Desoxycorticosterol, also known as 21-hydroxy-4-pregnene-3,20-dione or 21-hydroxyprogesterone, is a member of the class of compounds known as 21-hydroxysteroids. 21-hydroxysteroids are steroids carrying a hydroxyl group at the 21-position of the steroid backbone. Thus, desoxycorticosterol is considered to be a steroid lipid molecule. Desoxycorticosterol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Desoxycorticosterol can be synthesized from progesterone. Desoxycorticosterol can also be synthesized into 11-deoxycorticosterone-21-hemisuccinate and 5beta-dihydrodeoxycorticosterone. Desoxycorticosterol can be found in rice, which makes desoxycorticosterol a potential biomarker for the consumption of this food product. Desoxycorticosterol can be found primarily in amniotic fluid and blood, as well as throughout all human tissues. In humans, desoxycorticosterol is involved in the steroidogenesis. Desoxycorticosterol is also involved in several metabolic disorders, some of which include corticosterone methyl oxidase I deficiency (CMO I), 21-hydroxylase deficiency (CYP21), corticosterone methyl oxidase II deficiency - CMO II, and 11-beta-hydroxylase deficiency (CYP11B1). Desoxycorticosterol is a non-carcinogenic (not listed by IARC) potentially toxic compound.

Anatabine
Anatabine is one of the minor alkaloids found in plants in the family Solanaceae, which includes the tobacco plant and tomato. Commercial tobacco plants typically produce alkaloids at levels between 2\\\% and 4\\\% of total dry weight, with nicotine accounting for about 90\\\% of the total alkaloid content, and the related compounds anabatine, nornicotine, and anabasine making up nearly all the rest. These compounds are thought to be biologically active, and part of plants natural defense system against insects. It belongs to the class of organic compounds known as aralkylamines. These are alkylamines in which the alkyl group is substituted at one carbon atom by an aromatic hydrocarbyl group. Anatabine is tobacco alkaloid in urine of smokers and smokeless tobacco users (PMID: 8245163). This Nicotine-related alkaloid is an inhibitor of human cytochrome P-450 2A6 (PMID:14757175).

Geranial
Geranial, also known as 3,7-dimethyl-2,6-octadienal, citral or lemonal, belongs to the class of organic compounds known as acyclic monoterpenoids. These are monoterpenes that do not contain a cycle. Thus, citral is considered to be an isoprenoid lipid. Two different isomers of 3,7-dimethyl-2,6-octadienal exist. The E-isomer or trans-isomer is known as geranial or citral A. The Z-isomer or cis-isomer is known as neral or citral B. 3,7-dimethyl-2,6-octadienal is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Citral is present in the oils of several plants, including lemon myrtle (90-98\\\\%), Litsea citrata (90\\\\%), Litsea cubeba, lemongrass (65-80\\\\%), lemon tea-tree (70-80\\\\%), Ocimum gratissimum, Lindera citriodora, Calypranthes parriculata, petitgrain, lemon verbena, lemon ironbark, lemon balm, lime, lemon and orange. Citral has also been reported to be found in Cannabis sativa (PMID:6991645 , 26657499 ). Citral has a strong lemon (citrus) odor. Nerals lemon odor is less intense, but sweeter. Citral is therefore an aroma compound used in perfumery for its citrus effect. Citral is also used as a flavor and for fortifying lemon oil. It has strong antimicrobial qualities (PMID:28974979 ) and pheromonal effects in nematodes and insects (PMID:26973536 ).

Citral is a monoterpene found in Cymbopogon citratus essential oil, with antihyperalgesic, anti-nociceptive and anti-inflammatory effects[1].
Glutathione
Glutathione is a compound synthesized from cysteine, perhaps the most important member of the bodys toxic waste disposal team. Like cysteine, glutathione contains the crucial thiol (-SH) group that makes it an effective antioxidant. There are virtually no living organisms on this planet-animal or plant whose cells dont contain some glutathione. Scientists have speculated that glutathione was essential to the very development of life on earth. glutathione has many roles; in none does it act alone. It is a coenzyme in various enzymatic reactions. The most important of these are redox reactions, in which the thiol grouping on the cysteine portion of cell membranes protects against peroxidation; and conjugation reactions, in which glutathione (especially in the liver) binds with toxic chemicals in order to detoxify them. glutathione is also important in red and white blood cell formation and throughout the immune system. glutathiones clinical uses include the prevention of oxygen toxicity in hyperbaric oxygen therapy, treatment of lead and other heavy metal poisoning, lowering of the toxicity of chemotherapy and radiation in cancer treatments, and reversal of cataracts. (http://www.dcnutrition.com/AminoAcids/) 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 to S-D-Lactoyl-glutathione. Glyoxalase II (EC 3.1.2.6) catalyzes the hydrolysis of S-D-Lactoyl-glutathione to glutathione and D-lactate. GSH is known as a substrate in both conjugation reactions and reduction reactions, catalyzed by glutathione S-transferase enzymes in cytosol, microsomes, and mitochondria. However, it is also capable of participating in non-enzymatic conjugation with some chemicals, as in the case of n-acetyl-p-benzoquinone imine (NAPQI), the reactive cytochrome P450-reactive metabolite formed by acetaminophen, that becomes toxic when GSH is depleted by an overdose (of acetaminophen). glutathione in this capacity binds to NAPQI as a suicide substrate and in the process detoxifies it, taking the place of cellular protein thiol groups which would otherwise be covalently modified; when all GSH has been spent, NAPQI begins to react with the cellular proteins, killing the cells in the process. The preferred treatment for an overdose of this painkiller is the administration (usually in atomized form) of N-acetylcysteine, which is used by cells to replace spent GSSG and renew the usable GSH pool. (http://en.wikipedia.org/wiki/glutathione). Glutathione (GSH) - reduced glutathione - is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides. [Wikipedia]. Glutathione is found in many foods, some of which are cashew nut, epazote, ucuhuba, and canada blueberry. Glutathione. CAS Common Chemistry.

Dihomo-alpha-linolenic acid
Dihomolinolenic acid, also known as 11,14,17-eicosatrienoic acid or (11z,14z,17z)-eicosa-11,14,17-trienoic 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, dihomolinolenic acid is considered to be a fatty acid lipid molecule. Dihomolinolenic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Dihomolinolenic acid can be found in evening primrose, which makes dihomolinolenic acid a potential biomarker for the consumption of this food product. Dihomolinolenic acid can be found primarily in blood and feces. Dihomo-alpha-linolenic acid, also known as 11,14,17-eicosatrienoic acid, is a rare polyunsaturated fatty acid of the omega-3 series. In normal humans, it represents less than 0.25\\% of serum phospholipid fatty acids. However, it is one of the most active essential fatty acids when assayed for the inhibition of fatty acid elongation/desaturation reactions which convert dietary C-18 fatty acids to C-20 eicosanoid precursors.

3b-Allotetrahydrocortisol
3b-Allotetrahydrocortisol is one of the tetrahydrometabolites of cortisol. The 11-beta-hydroxysteroid dehydrogenase (11beta-HSD) is responsible for the interconversion of both the hormonally inactive cortisone and the active cortisol, which has implications in the pathogenesis of numerous diseases, as reflected in the ratio of tetrahydrometabolites of cortisol. (PMID: 16310418). The daily excretion of allotetrahydrocortisol is above normal in hyperthyroid patients; In contrast, in hyperthyroidism the excretion is diminished below normal levels to approximately half that of normal subjects. (PMID 13906284). A decreased activity of the enzyme 11beta-HSD produces a pattern of urinary steroid metabolites with an abnormal elevation of tetrahydrocortisol and allo-tetrahydrocortisol compared to tetrahydrocortisone; this pattern of steroid excretion is essential for the diagnosis of the syndrome of apparent mineralocorticoid excess type 1.

D-2-Hydroxyglutaric acid
In humans, D-2-hydroxyglutaric acid is formed by a hydroxyacid-oxoacid transhydrogenase whereas in bacteria it is formed by a 2-hydroxyglutarate synthase. D-2-Hydroxyglutaric acid is also formed via the normal activity of hydroxyacid-oxoacid transhydrogenase during conversion of 4-hydroxybutyrate to succinate semialdehyde. The compound can be converted to alpha-ketoglutaric acid through the action of a 2-hydroxyglutarate dehydrogenase (EC 1.1.99.2). In humans, there are two such enzymes (D2HGDH and L2HGDH). Both the D and the L stereoisomers of hydroxyglutaric acid are found in body fluids. D-2-Hydroxyglutaric acid is a biochemical hallmark of the inherited neurometabolic disorder D-2-hydroxyglutaric aciduria (OMIM: 600721) and the genetic disorder glutaric aciduria II. D-2-Hydroxyglutaric aciduria (caused by loss of D2HGDH or gain of function of IDH) is rare, with symptoms including cancer, macrocephaly, cardiomyopathy, mental retardation, hypotonia, and cortical blindness. An elevated urine level of D-2-hydroxyglutaric acid has been reported in patients with spondyloenchondrodysplasia (OMIM: 271550). D-2-Hydroxyglutaric acid can be converted to alpha-ketoglutaric acid through the action of 2-hydroxyglutarate dehydrogenase (D2HGDH). Additionally, the enzyme D-3-phosphoglycerate dehydrogenase (PHGDH) can catalyze the NADH-dependent reduction of alpha-ketoglutarate (AKG) to D-2-hydroxyglutarate (D-2HG). Nyhan et al. (1995) described 3 female patients, 2 of them sibs, who were found to have excess accumulation of D-2-hydroxyglutaric acid in the urine. The phenotype was quite variable, even among the sibs, but included mental retardation, macrocephaly with cerebral atrophy, hypotonia, seizures, and involuntary movements. One of the patients developed severe intermittent vomiting and was given a pyloromyotomy. The electroencephalogram demonstrated hypsarrhythmia. There was an increased concentration of protein in cerebrospinal fluid, an unusual finding in inborn errors of metabolism. D-2-Hydroxyglutaric acid can also be produced via gain-of-function mutations in the cytosolic and mitochondrial isoforms of isocitrate dehydrogenase (IDH). IDH is part of the TCA cycle and this compound is generated in high abundance when IDH is mutated. Since D-2-hydroxyglutaric acid is sufficiently similar in structure to 2-oxoglutarate (2OG), it is able to inhibit a range of 2OG-dependent dioxygenases, including histone lysine demethylases (KDMs) and members of the ten-eleven translocation (TET) family of 5-methylcytosine (5mC) hydroxylases. This inhibitory effect leads to alterations in the hypoxia-inducible factor (HIF)-mediated hypoxic response and alterations in gene expression through global epigenetic remodeling. The net effect is that D-2-hydroxyglutaric acid causes a cascading effect that leads genetic perturbations and malignant transformation. Depending on the circumstances, D-2-hydroxyglutaric acid can act as an oncometabolite, a neurotoxin, an acidogen, and a metabotoxin. An oncometabolite is a compound that promotes tumour growth and survival. A neurotoxin is compound that is toxic to neurons or nerual tissue. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. As an oncometabolite, D-2-hydroxyglutaric acid is a competitive inhibitor of multiple alpha-ketoglutarate-dependent dioxygenases, including histone demethylases and the TET family of 5mC hydroxylases. As a result, high levels of 2-hydroxyglutarate lead to genome-wide histone and DNA methylation alterations, which in turn lead to mutations that ultimately cause cancer (PMID: 29038145). As a neurotoxin, D-2-hydroxyglutaric acid mediates its neurotoxicity through activation of N-methyl-D-aspartate receptors. D-2-Hydroxyglutaric acid is structurally similar to the excitatory amino acid glutamate and stimul... Tissue accumulation of high amounts of D 2 hydroxyglutaric acid is the biochemical hallmark of the inherited neurometabolic disorder D 2 hydroxyglutaric aciduria.

Isoquinoline
Isoquinoline is a flavouring agent Being an analog of pyridine, isoquinoline is a weak base, with a pKb of 8.6. It protonates to form salts upon treatment with strong acids, such as HCl. It forms adducts with Lewis acids, such as BF3. Isoquinoline is a colorless hygroscopic liquid at room temperature with a penetrating, unpleasant odor. Impure samples can appear brownish, as is typical for nitrogen heterocycles. It crystallizes platelets that have a low solubility in water but dissolve well in ethanol, acetone, diethyl ether, carbon disulfide, and other common organic solvents. It is also soluble in dilute acids as the protonated derivative. Isoquinoline is a heterocyclic aromatic organic compound. It is a structural isomer of quinoline. Isoquinoline and quinoline are benzopyridines, which are composed of a benzene ring fused to a pyridine ring. In a broader sense, the term isoquinoline is used to make reference to isoquinoline derivatives. 1-Benzylisoquinoline is the structural backbone in naturally occurring alkaloids including papaverine and morphine. The isoquinoline ring in these natural compound derives from the aromatic amino acid tyrosine Flavouring agent KEIO_ID I067
1,3-Benzenediol
1,3-Benzenediol, also known as resorcin or m-hydroquinone, belongs to the class of organic compounds known as resorcinols. Resorcinols are compounds containing a resorcinol moiety, which is a benzene ring bearing two hydroxyl groups at positions 1 and 3. 1,3-Benzenediol exists in all living organisms, ranging from bacteria to humans. 1,3-Benzenediol is a creamy, hawthorn, and musty tasting compound. 1,3-Benzenediol has been detected, but not quantified, in several different foods, such as alcoholic beverages, cereals and cereal products, coffee and coffee products, eggplants, and java plums. This could make 1,3-benzenediol a potential biomarker for the consumption of these foods. 1,3-Benzenediol is a potentially toxic compound. In addition, exogenous ochronosis is associated with prolonged exposure to resorcinol . Data regarding the specific mechanisms of action of resorcinol does not appear to be readily accessible in the literature. Nevertheless, the role played by iodide ions in the irreversible inactivation of the enzymes is not yet fully elucidated . Resorcinol works by helping to remove hard, scaly, or roughened skin. In particular, it appears that resorcinol indicated for treating acne, dermatitis, or eczema in various skin care topical applications and peels revolves around the compounds ability to precipitate cutaneous proteins from the treated skin . In LPO and TPO, the resulting π-cation radical of the porphyrin can isomerize to a radical cation with the radical in an aromatic side chain of the enzyme . In vitro and in vivo studies have demonstrated that resorcinol can inhibit peroxidases in the thyroid and subsequently block the synthesis of thyroid hormones and cause goiter . Present in roasted barley, cane molasses, coffee, beer and wine. Flavouring ingredient. 1,3-Benzenediol is found in many foods, some of which are cereals and cereal products, coffee and coffee products, alcoholic beverages, and java plum.

Thiamine
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.

Xanthophylls are yellow pigments and form one of two major divisions of the carotenoid group; the other division is formed by the carotenes. Both are carotenoids. Xanthophylls and carotenes are similar in structure, but xanthophylls contain oxygen atoms while carotenes are purely hydrocarbons, which do not contain oxygen. Their content of oxygen causes xanthophylls to be more polar (in molecular structure) than carotenes and causes their separation from carotenes in many types of chromatography. (Carotenes are usually more orange in color than xanthophylls. Canthaxanthin is naturally found in bacteria, algae and some fungi. Canthaxanthin is associated with E number E161g and is approved for use as a food coloring agent in different countries, including the United States and the EU. Canthaxanthin is used as poultry feed additive to yield red color in skin and yolks. The European Union permits the use of canthaxanthin in feedstuff at a maximum content of 25 mg/kg of final feedstuff while the United States allows the use of this pigment in broiler chicken and salmonid fish feeds. Canthoxanthin was first isolated in edible chanterelle mushroom (Cantharellus cinnabarinus), from which it derived its name. It has also been found in green algae, bacteria, archea (a halophilic archaeon called Haloferax alexandrines), fungi and bioaccumulates in tissues and egg yolk from wild birds and at low levels in crustaceans and fish such as carp, golden grey mullet, and seabream. Canthaxanthin is not found in wild Atlantic Salmon, but is a minor carotenoid in Pacific Salmon. Canthaxanthin is used in farm-raised trout to give a red/orange color to their flesh similar to wild trout. Canthaxanthin has been used as a food additive for egg yolk, in cosmetics and as a pigmenting agent for human skin applications. It has also been used as a feed additive in fish and crustacean farms. Canthaxanthin is a potent lipid-soluble antioxidant (PMID: 2505240). Canthaxanthin increases resistance to lipid peroxidation primarily by enhancing membrane alpha-tocopherol levels and secondarily by providing weak direct antioxidant activity. Canthaxanthin biosynthesis in bacteria and algae proceeds from beta-carotene via the action of an enzyme known as a beta-carotene ketolase, that is able to add a carbonyl group to carbon 4 and 4 of the beta carotene molecule.

Hydroquinone
Hydroquinone, also benzene-1,4-diol, is an aromatic organic compound which is a type of phenol, having the chemical formula C6H4(OH)2. Its chemical structure has two hydroxyl groups bonded to a benzene ring in a para position. Hydroquinone is commonly used as a biomarker for benzene exposure. The presence of hydroquinone in normal individuals stems mainly from direct dietary ingestion, catabolism of tyrosine and other substrates by gut bacteria, ingestion of arbutin containing foods, cigarette smoking, and the use of some over-the-counter medicines. Hydroquinone is a white granular solid at room temperature and pressure. The hydroxyl groups of hydroquinone are quite weakly acidic. Hydroquinone can lose an H+ from one of the hydroxyls to form a monophenolate ion or lose an H+ from both to form a diphenolate ion. Hydroquinone has a variety of uses principally associated with its action as a reducing agent which is soluble in water. It is a major component in most photographic developers where, with the compound Metol, it reduces silver halides to elemental silver. [HMDB].

Coenzyme Q10
Coenzyme Q10 (ubiquinone) is a naturally occurring compound widely distributed in animal organisms and in humans. The primary compounds involved in the biosynthesis of ubiquinone are 4-hydroxybenzoate and the polyprenyl chain. An essential role of coenzyme Q10 is as an electron carrier in the mitochondrial respiratory chain. Moreover, coenzyme Q10 is one of the most important lipophilic antioxidants, preventing the generation of free radicals as well as oxidative modifications of proteins, lipids, and DNA, it and can also regenerate the other powerful lipophilic antioxidant, alpha-tocopherol. Antioxidant action is a property of the reduced form of coenzyme Q10, ubiquinol (CoQ10H2), and the ubisemiquinone radical (CoQ10H*). Paradoxically, independently of the known antioxidant properties of coenzyme Q10, the ubisemiquinone radical anion (CoQ10-) possesses prooxidative properties. Decreased levels of coenzyme Q10 in humans are observed in many pathologies (e.g. cardiac disorders, neurodegenerative diseases, AIDS, cancer) associated with intensive generation of free radicals and their action on cells and tissues. In these cases, treatment involves pharmaceutical supplementation or increased consumption of coenzyme Q10 with meals as well as treatment with suitable chemical compounds (i.e. folic acid or B-group vitamins) which significantly increase ubiquinone biosynthesis in the organism. Estimation of coenzyme Q10 deficiency and efficiency of its supplementation requires a determination of ubiquinone levels in the organism. Therefore, highly selective and sensitive methods must be applied, such as HPLC with UV or coulometric detection. For a number of years, coenzyme Q (CoQ10 in humans) was known for its key role in mitochondrial bioenergetics; later studies demonstrated its presence in other subcellular fractions and in plasma, and extensively investigated its antioxidant role. These two functions constitute the basis on which research supporting the clinical use of CoQ10 is founded. Also at the inner mitochondrial membrane level, coenzyme Q is recognized as an obligatory co-factor for the function of uncoupling proteins and a modulator of the transition pore. Furthermore, recent data reveal that CoQ10 affects expression of genes involved in human cell signalling, metabolism, and transport and some of the effects of exogenously administered CoQ10 may be due to this property. Coenzyme Q is the only lipid soluble antioxidant synthesized endogenously. In its reduced form, CoQH2, ubiquinol, inhibits protein and DNA oxidation but it is the effect on lipid peroxidation that has been most deeply studied. Ubiquinol inhibits the peroxidation of cell membrane lipids and also that of lipoprotein lipids present in the circulation. Dietary supplementation with CoQ10 results in increased levels of ubiquinol-10 within circulating lipoproteins and increased resistance of human low-density lipoproteins to the initiation of lipid peroxidation. Moreover, CoQ10 has a direct anti-atherogenic effect, which has been demonstrated in apolipoprotein E-deficient mice fed with a high-fat diet. (PMID: 15928598, 17914161).

Molybdenum
Molybdenum is a transition metal with the atomic symbol Mo, atomic number 42, and atomic weight 95.94. The pure metal is silvery white in color, fairly soft, and has one of the highest melting points of all pure elements. Physiologically, it exists as an ion in the body. It is an essential trace element, being a component of the enzymes xanthine oxidase, aldehyde oxidase, and nitrate reductase. There is a trace requirement for molybdenum in plants, and soils can be barren due to molybdenum deficiencies. Plants and animals generally have molybdenum present in amounts of a few parts per million. In animals molybdenum is a cofactor of the enzyme xanthine oxidase which is involved in the pathways of purine degradation and formation of uric acid. In some animals, adding a small amount of dietary molybdenum enhances growth. Francis Crick suggested that since molybdenum is an essential trace element that plays an important role in many enzymatic reactions, despite being less abundant than the more common elements, such as chromium and nickel, that perhaps this fact is indicative of "Panspermia." Crick theorized that if it could be shown that the elements represented in terrestrial living organisms correlate closely with those that are abundant in some class of star - molybdenum stars, for example, that this would provide evidence of such Directed Panspermia. In small quantities, molybdenum is effective at hardening steel. Molybdenum is important in plant nutrition, and is found in certain enzymes, including xanthine oxidase. Molybdenum is used to this day in high-strength alloys and in high-temperature steels. Special molybdenum-containing alloys, such as the Hastelloys, are notably heat-resistant and corrosion-resistant. Molybdenum is used in oil pipelines, aircraft and missile parts, and in filaments. Molybdenum finds use as a catalyst in the petroleum industry, especially in catalysts for removing organic sulfurs from petroleum products. It is used to form the anode in some x-ray tubes, particularly in mammography applications. And is found in some electronic applications as the conductive metal layers in thin-film transistors (TFTs). Molybdenum disulfide is a good lubricant, especially at high temperatures. And Mo-99 is used in the nuclear isotope industry. Molybdenum pigments range from red-yellow to a bright red orange and are used in paints, inks, plastics, and rubber compounds. Molybdenum is a Group 6 chemical element with the symbol Mo and atomic number 42. The free element, which is a silvery metal, has the sixth-highest melting point of any element. It readily forms hard, stable carbides, and for this reason it is often used in high-strength steel alloys. Molybdenum does not occur as a free metal on Earth, but rather in various oxidation states in minerals. Industrially, molybdenum compounds are used in high-pressure and high-temperature applications, as pigments and catalysts. Molybdenum-containing enzymes are used as catalysts by some bacteria to break the chemical bond in atmospheric molecular nitrogen, allowing biological nitrogen fixation. At least 50 molybdenum-containing enzymes are now known in bacteria and animals, though only the bacterial and cyanobacterial enzymes are involved in nitrogen fixation. Owing to the diverse functions of the remainder of the enzymes, molybdenum is a required element for life in higher organisms (eukaryotes), though not in all bacteria. [Wikipedia]. Molybdenum is found in many foods, some of which are cabbage, gooseberry, french plantain, and turnip. D018977 - Micronutrients > D014131 - Trace Elements

Methylamine
Methylamine occurs endogenously from amine catabolism and its tissue levels increase in some pathological conditions, including diabetes. Interestingly, methylamine and ammonia levels are reciprocally controlled by a semicarbazide-sensitive amine oxidase activity that deaminates methylamine to formaldehyde with the production of ammonia and hydrogen peroxide. Methylamine also targets the voltage-operated neuronal potassium channels, probably inducing release of neurotransmitter(s). Semicarbazide-sensitive amine oxidase (SSAO) catalyzes the deamination of primary amines. Such deamination has been shown capable of regulating glucose transport in adipose cells. It has been independently discovered that the primary structure of vascular adhesion protein-1 (VAP-1) is identical to SSAO. Increased serum SSAO activities have been found in patients with diabetic mellitus, vascular disorders, and Alzheimers disease. The SSAO-catalyzed deamination of endogenous substrates like methylamine led to production of toxic formaldehyde. Chronic elevated methylamine increases the excretion of malondialdehyde and microalbuminuria. Amine oxidase substrates such as methylamine have been shown to stimulate glucose uptake by increasing the recruitment of the glucose transporter GLUT4 from vesicles within the cell to the cell surface. Inhibition of this effect by the presence of semicarbazide and catalase led to the suggestion that the process is mediated by the hydrogen peroxide produced in the oxidation of these amines (PMID: 16049393 , 12686132 , 17406961). Methylamine has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Methylamine is a colourless gas derivative of ammonia, but with one H atom replaced by a methyl group. It is the simplest primary amine. It has a strong odor similar to fish. Methylamine is used as a building block for the synthesis of many other commercially available compounds. Hundreds of millions of kilograms are produced annually. Methylamine is found in many foods, some of which are french plantain, tea, barley, and wild celery.

Glyceric acid 1,3-biphosphate (CAS: 1981-49-3), also known as 1,3-bisphosphoglycerate (1,3BPG) or PGAP, is a 3-carbon organic molecule present in most, if not all living creatures. It primarily exists as a metabolic intermediate in glycolysis during respiration. 1,3BPG has been recognized as regulatory signal implicated in the control of metabolism, oxygen affinity of red cells, and other cellular functions. 1,3BPG concentration in erythrocytes changes in a number of pathological conditions, such as inherited phosphoglycerate kinase deficiency in erythrocytes (involved in the synthesis and breakdown of 1,3BPG) (PMID: 3555887). Glyceric acid 1,3-biphosphate is phosphorylated at the number 1 and 3 carbons.

Prephenate
Prephenate (CAS: 126-49-8), also known as prephenic acid, belongs to the class of organic compounds known as gamma-keto acids and derivatives. These are organic compounds containing an aldehyde substituted with a keto group on the C4 carbon atom. Prephenic acid is an example of an achiral (optically inactive) molecule which has two pseudoasymmetric atoms (i.e. stereogenic but not chirotopic centers): the C1 and the C4 cyclohexadiene ring atoms. Prephenate exists in all living species, ranging from bacteria to humans. Prephenate has been detected, but not quantified, in several different foods, such as American pokeweeds, breadnut tree seeds, common wheats, swiss chards, and breadfruits. The other stereoisomer, i.e. trans or, better, (1r, 4r), is called epiprephenic acid. It has been shown that of the two possible diastereoisomers, the natural prephenic acid is one that has both substituents at higher priority (according to CIP rules) on the two pseudoasymmetric carbons, i.e. the carboxyl and the hydroxyl groups, in the cis configuration, or (1s, 4s) according to the new IUPAC stereochemistry rules (2013). It is biosynthesized by a [3,3]-sigmatropic Claisen rearrangement of chorismate. Prephenic acid, commonly also known by its anionic form prephenate, is an intermediate in the biosynthesis of the aromatic amino acids phenylalanine and tyrosine, as well as of a large number of secondary metabolites of the shikimate pathway.

3-Hydroxy-3-methylglutaryl-CoA
3-Hydroxy-3-methylglutaryl-CoA (HMG-CoA) (CAS: 1553-55-5) is formed when acetyl-CoA condenses with acetoacetyl-CoA in a reaction that is catalyzed by the enzyme HMG-CoA synthase in the mevalonate pathway or mevalonate-dependent (MAD) route, an important cellular metabolic pathway present in virtually all organisms. HMG-CoA reductase (EC 1.1.1.34) inhibitors, more commonly known as statins, are cholesterol-lowering drugs that have been widely used for many years to reduce the incidence of adverse cardiovascular events. HMG-CoA reductase catalyzes the rate-limiting step in the mevalonate pathway and these agents lower cholesterol by inhibiting its synthesis in the liver and in peripheral tissues. Androgen also stimulates lipogenesis in human prostate cancer cells directly by increasing transcription of the fatty acid synthase and HMG-CoA-reductase genes (PMID: 14689582). (s)-3-hydroxy-3-methylglutaryl-coa, also known as hmg-coa or hydroxymethylglutaroyl coenzyme a, is a member of the class of compounds known as (s)-3-hydroxy-3-alkylglutaryl coas (s)-3-hydroxy-3-alkylglutaryl coas are 3-hydroxy-3-alkylglutaryl-CoAs where the 3-hydroxy-3-alkylglutaryl component has (S)-configuration.

Superoxide
Superoxide is the anionic form O2. It is important as the product of the one-electron reduction of dioxygen (oxygen gas), which occurs widely in nature. With one unpaired electron, the superoxide ion is a free radical. It is also paramagnetic. The biological toxicity of superoxide is due to its capacity to inactivate iron-sulfur cluster containing enzymes (which are critical in a wide variety of metabolic pathways), thereby liberating free iron in the cell, which can undergo fenton-chemistry and generate the highly reactive hydroxyl radical. In its HO2 form, superoxide can also initiate lipid peroxidation of polyunsaturated fatty acids. It also reacts with carbonyl compounds and halogenated carbons to create toxic peroxy radicals. As such, superoxide is a main cause of oxidative stress. Highly reactive compounds produced when oxygen is reduced by a single electron. In biological systems, they may be generated during the normal catalytic function of a number of enzymes and during the oxidation of hemoglobin to Methemoglobin. Because superoxide is toxic, nearly all organisms living in the presence of oxygen contain isoforms of the superoxide scavenging enzyme, superoxide dismutase, or SOD. SOD is an extremely efficient enzyme; it catalyzes the neutralization of superoxide nearly as fast as the two can diffuse together spontaneously in solution. Genetic inactivation ("knockout") of SOD produces deleterious phenotypes in organisms ranging from bacteria to mice. The latter species dies around 21 days after birth if the mitochondrial variant of SOD (Mn-SOD) is inactivated, and suffers from multiple pathologies, including reduced lifespan, liver cancer, muscle atrophy, cataracts and female infertility when the cytoplasmic (Cu, Zn -SOD) variant is inactivated. With one unpaired electron, the superoxide ion is a free radical and therefore paramagnetic. In living organisms, superoxide dismutase protects the cell from the deleterious effects of superoxides.

3-Dehydroquinic acid
3-Dehydroquinic acid belongs to the class of organic compounds known as alpha-hydroxy acids and derivatives. These are organic compounds containing a carboxylic acid substituted with a hydroxyl group on the adjacent carbon. 3-Dehydroquinic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). In most organisms, 3-dehydroquinic acid is synthesized from D-erythrose-4-phosphate in two steps. However, archaea genomes contain no orthologs for the genes that encode these first two steps. Instead, archaeabacteria appear to utilize an alternative pathway in which 3-dehydroquinic acid is synthesized from 6-deoxy-5-ketofructose-1-phosphate and L-aspartate-semialdehyde. These two compounds are first condensed to form 2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate, which cyclizes to 3-dehydroquinic acid. From 3-dehydroquinic acid and on to chorismate, the archaeal pathway appears to be identical to the bacterial pathway.

3-Hydroxypropanal
3-Hydroxypropanal is a broad-spectrum antimicrobial substance termed reuterin produced by Lactobacillus reuteri. L. reuteri resides in the gastrointestinal tract of healthy humans and animals, and is believed to. function as a symbiont in the enteric ecosystem. Synthesis of such an antimicrobial substance by an enteric resident raises a number of interesting questions and possibilities as to the role these residents may play in the health of the host. (PMID 3245697). In vivo, glycerol is converted in one enzymatic step into 3-Hydroxypropanal. The 3-Hydroxypropanal -producing Lactobacillus reuteri is used as a probiotic in the health care of humans and animals. 3-Hydroxypropanal forms, together with Hydroxypropanal-hydrate and Hydroxypropanal-dimer, a dynamic, multi-component system (Hydroxypropanal system) used in food preservation, as a precursor for many modern chemicals such as acrolein, acrylic acid, and 1,3-propanediol (1,3-PDO), and for polymer production. 3-Hydroxypropanal can be obtained both through traditional chemistry and bacterial fermentation. To date, 3-HPA has been produced from petrochemical resources as an intermediate in 1,3-PDO production. The biotechnological production of 3-Hydroxypropanal from renewable resources is desirable both for use of 3-Hydroxypropanal in foods and for the production of bulk chemicals. The main challenge will be the efficient production and recovery of pure 3-Hydroxypropanal.

Methane
Methane (CH4), is a gas produced by a group of colonic anaerobes, absorbed from the colon and excreted in expired air. As a result, breath CH4 excretion can be used as an indicator of the in situ activity of the methanogenic flora. All CH4 produced in human beings is a metabolic product of intestinal bacteria, and about 50\\% of CH4 produced in the gut is absorbed and excreted in expired air. Because there appears to be no catabolism of this gas by other colonic organisms or host cells, breath CH4 measurements provide a rapid, simple means of semi quantitatively assessing the ongoing in situ metabolism of the methanogenic flora. It could seem likely that the intracolonic activity of a variety of bacteria similarly might be assessed quantitatively via analysis of expired air. However, the application of this methodology has been confounded by the rapid catabolism of many volatile bacterial products by other bacteria or human tissue. A striking aspect of the studies of breath CH4 measurements is the enormous individual variations in the excretion of this gas. Virtually all children under 5 years of age and 66\\% of the adult population do not exhale appreciable quantities of CH4. The remaining 34\\% of the adult population has appreciable breath methane concentrations of up to 80 ppm (mean, 15.2 ppm; median, 11.8 ppm). On this basis the population can be divided into CH4 producers or nonproducers, although a more accurate term would be to define subjects as being low or high CH4 producers. The primary methanogen present in the human colon, Methanobrevibacter smithii, produces methane via a reaction that relies entirely on H2 produced by other organisms to reduce CO2 to CH4. Thus, breath CH4 concentrations might be expected to mirror breath H2 concentrations; however, the high levels of CH4 observed in the fasting state may result from H2 derived from endogenous rather than dietary substrates. A diverse assortment of conditions has been associated with a high prevalence of methane producers including diverticulosis, cystic fibrosis, high fasting serum cholesterol levels, encopresis in children, and aorto-iliac vascular disease, whereas obesity (measured as skin-fold thickness) was related inversely to methane production. The challenge that remains is to determine to what extent methanogens actively influence body physiology vs. simply serve as passive indicators of colonic function. (PMID: 16469670, Clinical Gastroenterology and Hepatology Volume 4, Issue 2, February 2006, Pages 123-129). Methane can be found in Desulfovibrio, Methanobacterium, Methanobrevibacter, Methanococcus, Methanocorpusculum, Methanoculleus, Methanoflorens, Methanofollis, Methanogenium, Methanomicrobium, Methanopyrus, Methanoregula, Methanosaeta, Methanosarcina, Methanosphaera, Methanospirillium, Methanothermobacter (Wikipedia).

L-Dopachrome
Dopachrome is a cyclization product of L-DOPA and is an intermediate in the biosynthesis of melanin. Dopaquinone has an ortho-quinone ring, which is known to be neurotoxic and highly reactive with many other compounds (PMID: 413870). Dopachrome spontaneously gives rise to 5,6-dihydroxyindole (DHI) or it can be enzymatically metabolized by dopachrome tautomerase to give 5,6-dihydroxyindole-2-carboxylic acid (DHICA). DHI and its oxidation products are also toxic to cells. Many Parkinsons patients are treated with L-DOPA. However, long-term treatment with L-DOPA may actually worsen symptoms or may result in neurotic and psychotic symptoms. These may be due to dopachrome and dopaquinone accumulating in the brain of L-DOPA treated patients (PMID: 19131041, PMID: 12373519). The non-decarboxylative tautomerization of L-dopachrome to 5,6-dihydroxyindole-2-carboxylic acid in the melanin biosynthetic pathway is catalyzed by Tyrosinase-related protein-2, a melanocyte-specific enzyme. (PMID 11095412) [HMDB]

Stearaldehyde or octadecanal is a normal long chain fatty aldehyde that can be found in total lipid extracts of muscle tissue. Stearaldehyde can also be found in the plasma of patients with Sjogren-Larsson syndrome. Sjogren-Larsson syndrome (SLS) is an autosomal recessively inherited neurocutaneous disorder caused by a deficiency of the microsomal enzyme fatty aldehyde dehydrogenase (FALDH). (PMID 14564703, 11408337). Octadecanal is often used as the substrate of choice to test FALDH activity in patients suspected of having Sjogren-Larsson syndrome.

Protochlorophyllide
Protochlorophyllide is found in fruits. Protochlorophyllide is isolated from the seed husks of Cucurbita pepo Chlorophyll itself is bound to proteins and can transfer the absorbed energy in the required direction. Protochlorophyllide, differently, mostly occurs in the free form and under light conditions acts as photosensitizer, forming highly toxic free radicals. Hence plants need an efficient mechanism of regulating the amount of chlorophyll precursor. In angiosperms, this is done at the step of D-Aminolevulinic acid (ALA), one of the intermediate compounds in the biosynthesis pathway. Plants that are fed by ALA accumulate high and toxic levels of protochlorophyllide, so do the mutants with the damaged regulatory system. Despite of numerous past attempts to find the mutant that overacumulates protochlorophyllide under usual conditions, only one such gene (flu) is currently (2009) known. Flu (first described in ) is a nuclear - encoded, chloroplast - located protein that appears containing only protein - protein interaction sites. It is currently not know which other proteins interact through this linker. The regulatory protein is a transmembrane protein that is located in the thylakoid membrane. Later it was discovered that Tigrina mutants in barley, known long time ago, are also mutated in the same gene It is not obvious why no mutants of any other gene were observed; maybe mutations in other proteins, involved into the regulatory chain, are fatal. Flu is a single gene, not a member of the gene family. Protochlorophyllide , more accurate monovinyl protochlorophyllide, is an immediate precursor of chlorophyll a that lacks the phytol side chain of chlorophyll. Unlike chlorophyll, protochlorophyllide is highly fluorescent; mutants that accumulate it glow in red if irradiated by the blue lightIn Angiosperms, the last step, conversion of protochlorophyllide to chlorophyll, is light - dependent and such plants are pale (etiolated) if grown in the darkness. Gymnosperms, algae, and photosynthetic bacteria additionally have another, light - independent enzyme and grow green in the darkness as well. The enzyme that converts protochlorophyllide to chlorophyll is protochlorophyllide reductase , EC 1.3.1.33. There are two structurally unrelated proteins with this activity: the light - dependent and the dark - operative. The light dependent reductase needs light to operate. The dark - operative version is a completely different protein, consisting of three subunits that exhibit significant sequence similarity to the three subunits of nitrogenase, which catalyzes the formation of ammonia from dinitrogen. This enzyme might be evolutionary older but (being similar to nitrogenase) is highly sensitive to free oxygen and does not work if its concentration exceeds about 3 \\%. Hence the alternative, light dependent version needed to evolve
Propylene glycol
Propylene glycol (CAS: 57-55-6), also known as 1,2-propanediol, is an organic compound (a diol alcohol), usually a tasteless, odourless, and colourless clear oily liquid that is hygroscopic and miscible with water, acetone, and chloroform. It is manufactured by the hydration of propylene oxide. Propylene glycol is used as a solvent for intravenous, oral, and topical pharmaceutical preparations It is generally considered safe. However, in large doses, it can be toxic, especially if given over a short period of time. Intravenous lorazepam contains the largest amount of propylene glycol of commonly used drugs. In adults with normal liver and kidney function, the terminal half-life of propylene glycol ranges from 1.4 to 3.3 hours. Propylene glycol is metabolized by the liver to form lactate, acetate, and pyruvate. The nonmetabolized drug is excreted in the urine mainly as the glucuronide conjugate, approximately 12 to 45 percent is excreted unchanged in urine. Renal clearance decreases as the dose administered increases (390 ml/minute/173 m2 at a dose of 5 g/day but only 144 ml/minute/173 m2 at a dose of 21 g/day). These data suggest that renal clearance declines at higher propylene glycol doses because of the saturation of proximal tubular secretion of the drug. As an acceptable level of propylene glycol has not been defined, the clinical implication of a propylene glycol level is unclear. The World Health Organization (WHO) recommends a maximum consumption of 25 mg/kg/day (1.8 g/day for a 75 kg male) of propylene glycol when used as a food additive, but this limit does not address its use as a drug solvent. No maximum dose is recommended in the literature for intravenous therapy with propylene glycol. Intoxication occurs at much higher doses than the WHO dose limit and is exclusive to pharmacologic exposure. Propylene glycol toxicity includes the development of serum hyperosmolality, lactic acidosis, and kidney failure. It has been suggested that proximal tubular necrosis is the cause of acute kidney injury from propylene glycol. Along these lines, proximal tubular cell injury occurs in cultured human cells exposed to propylene glycol. Acute tubular necrosis was described with propylene glycol toxicity in a case of concomitant administration of intravenous lorazepam and trimethoprim sulfamethoxazole. Propylene glycol induced intoxication can also mimic sepsis or systemic inflammatory response syndrome (SIRS). Patients suspected of having sepsis with negative cultures should be evaluated for propylene glycol toxicity if they have been exposed to high dose lorazepam or other medications containing this solvent (PMID:17555487). Propylene glycol is an anticaking agent, antioxidant, dough strengthener, emulsifier, flavouring agent, formulation aid, humectant, solvent, preservative, stabiliser, hog/poultry scald agent, and surface active agent. It is found in foods such as roasted sesame seeds, oats, truffle and other mushrooms.

Leucodopachrome
Leucodopachrome is an indolic intermediate in the melanogenesis pathway, the non-enzymatically product of dopaquinone through cyclization in a reaction whose operation is determined by a pH greater than 4 (melanin synthesis in human pigment cell lysates is maximal at pH 6.8). Leucodopachrome participates in redox exchange with dopaquinone to give the eumelanin precursor dopachrome plus dopa. Dopaquinone (the quinone intermediate resulting from tyrosinase-mediated oxidation of tyrosine, monophenol dihydroxyphenylalanine:oxygen oxidoreductase, EC 1.14.18.1) could be a toxic metabolite in melanin biosynthesis. (PMID: 6807981, 1445949, 413870, 11461115, 11171088, 12755639) [HMDB]. Leucodopachrome is found in many foods, some of which are chives, saffron, leek, and red beetroot.

Dopaquinone (the quinone intermediate resulting from tyrosinase-mediated oxidation of tyrosine, monophenol dihydroxyphenylalanine:oxygen oxidoreductase, EC 1.14.18.1) could be a toxic metabolite in melanin biosynthesis (PMID: 6807981, 1445949, 413870, 11461115, 11171088, 12755639).
Selenocystine
Selenocystine, also known as 3,3-diselenodialanine, belongs to the class of organic compounds known as alpha-amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxyl group (alpha carbon). More specifically, selenocystine is a diselenide consisting of two selenoamino acids that are attached together at their selenium atoms. This particular selenoamino acid is selenocysteine, the selenium analogue to cysteine (selenium being the element directly beneath sulphur in the periodic table); likewise, selenocystine is the selenium analogue to cystine. Since each constituent amino acid has a stereocentre, there are three different stereoisomers of selenocystine: D-selenocystine, L-selenocystine, and meso-selenocystine, the first two of which are optically active. Like other amino acids, L-selenocystine is the most common form within organisms; however, the D- and meso- forms have also been found (PMID: 30920149). Selenocystine is a solid that is moderately soluble in water. Due to the reactivity of selenocysteine, it is rarely encountered; rather, cells store selenium in the less reactive oxidized form of selenocystine or in a methylated form, such as selenomethionine (DOI: 10.1007/978-3-319-92405-2_3). When cells are grown in the absence of selenium, translation of selenoproteins terminates at the UGA codon, resulting in a truncated, non-functional enzyme. Unlike other amino acids present in biological proteins, selenocysteine is not coded for directly in the genetic code. Rather, the tRNA-bound seryl residue is converted to a selenocysteine residue by the pyridoxal phosphate-containing enzyme selenocysteine synthase (PMID: 17194211). Kurt Franke et al. indicated that there was evidence that selenium was in a form similar to that of cysteine, predating Thressa Stadtman’s discovery of the 21st amino acid by four decades (PMID: 26949981; J. Biol. Chem. 111:643). Selenocysteine may be denoted by the short forms Sec, U, or SeCys (Cys is used for cysteine), whereas selenocystine may be denoted by SeCys2. However, the literature sometimes uses SeCys for selenocystine and may cause confusion. Selenocystine has been found in animals, plants, and bacteria. It is being researched as treatment for cancer and for its antioxidant properties (PMID: 24763048, 24030774). Selenium, in its various forms such as selenocystine, is essential for many species, including humans, yet it is also toxic to all organisms; hence, it has come to be referred to as the “essential poison” (PMID: 26949981; 6679541). Selenocystine is a substrate for glutathione peroxidase 1. [HMDB] D000890 - Anti-Infective Agents > D000998 - Antiviral Agents L-Selenocystine is a diselenide-bridged amino acid. L-Selenocystine is a redox-active selenium compound that has both anti- and pro-oxidant actions. L-Selenocystine induces an unfolded protein response, ER stress, and large cytoplasmic vacuolization in HeLa cells and has cytostatic effects in a range of cancer cell types[1].

Carboxyphosphamide
In contrast to previous adult studies on urinary metabolites, plasma carboxyphosphamide concentrations did not support the existence of polymorphic metabolism.

Isoprene is produced by many plants, and its polymers are the main component of natural rubber. C. G. Williams named the compound in 1860 after obtaining it from thermal decomposition (pyrolysis) of natural rubber; he correctly deduced the empirical formula C5H8 .
Maltose
D-Maltose, also known as maltose, maltobiose or malt sugar, is a disaccharide formed from two units of glucose joined with an alpha (1‚Üí4) bond. Its name comes from malt, combined with the suffix -ose which is used in names of sugars. Maltose is a key structural motif of starch. When alpha-amylase breaks down starch, it removes two glucose units at a time, producing maltose. Maltose can be further broken down to glucose by the maltase enzyme, which catalyses the hydrolysis of the glycosidic bond. D-maltose exists in all living species, ranging from bacteria to plants to humans. Within humans, D-maltose participates in a number of enzymatic reactions. In particular, maltose can be converted into glucose; which is mediated by the enzyme maltase-glucoamylase. In addition, maltose can be converted into glucose through its interaction with the enzyme glycogen debranching enzyme. Maltose is found in high concentrations in oriental wheats and in a lower concentrations in sweet potato, grape wines, yellow pond-lilies, sunflowers, and spinach. Maltose is a component of malt, a substance which is obtained in the process of allowing grain to soften in water and germinate. It is also present in highly variable quantities in partially hydrolysed starch products like maltodextrin, corn syrup and acid-thinned starch. Maltose has a sweet taste but is only about 30‚Äì60\\\\% as sweet as sucrose, depending on the concentration. Sweetening agent, dietary supplement.

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

(R)-Lipoic acid
A vitamin-like antioxidant that acts as a free-radical scavenger. Alpha-lipoic acid is also known as thioctic acid. It is a naturally occurring compound that is synthesized by both plants and animals. Lipoic acid contains two thiol groups which may be either oxidized or reduced. The reduced form is known as dihydrolipoic acid (DHLA). Lipoic acid (Delta E= -0.288) is therefore capable of thiol-disulfide exchange, giving it antioxidant activity. Lipoate is a critical cofactor for aerobic metabolism, participating in the transfer of acyl or methylamine groups via the 2-Oxoacid dehydrogenase (2-OADH) or alpha-ketoglutarate dehydrogenase complex. This enzyme catalyzes the conversion of alpha-ketoglutarate to succinyl CoA. This activity results in the catabolism of the branched chain amino acids (leucine, isoleucine and valine). Lipoic acid also participates in the glycine cleavage system(GCV). The glycine cleavage system is a multi-enzyme complex that catalyzes the oxidation of glycine to form 5,10 methylene tetrahydrofolate, an important cofactor in nucleic acid synthesis. Since Lipoic acid is an essential cofactor for many enzyme complexes, it is essential for aerobic life as we know it. This system is used by many organisms and plays a crucial role in the photosynthetic carbon cycle. Lipoic acid was first postulated to be an effective antioxidant when it was found it prevented vitamin C and vitamin E deficiency. It is able to scavenge reactive oxygen species and reduce other metabolites, such as glutathione or vitamins, maintaining a healthy cellular redox state. Lipoic acid has been shown in cell culture experiments to increase cellular uptake of glucose by recruiting the glucose transporter GLUT4 to the cell membrane, suggesting its use in diabetes. Studies of rat aging have suggested that the use of L-carnitine and lipoic acid results in improved memory performance and delayed structural mitochondrial decay. As a result, it may be helpful for people with Alzheimers disease or Parkinsons disease. -- Wikipedia [HMDB] Lipoic acid is a vitamin-like antioxidant that acts as a free-radical scavenger.

2-Hydroxyglutarate
2-Hydroxyglutarate exists in 2 isomers: L-2-hydroxyglutarate acid and D-2-hydroxyglutarate. Both the D and the L stereoisomers of hydroxyglutaric acid (EC 1.1.99.2) are found in body fluids. In humans it is part of butanoate metabolic pathway and can be produced by phosphoglycerate dehydrogenase (PHGDH). More specifically, the enzyme PHGDH catalyzes the NADH-dependent reduction of ?-ketoglutarate (AKG) to D-2-hydroxyglutarate (D-2HG). 2-hydroxyglutarate is also the product of gain-of-function mutations in the cytosolic and mitochondrial isoforms of isocitrate dehydrogenase (IDH). Additionally, 2-hydroxyglutarate can be converted to ?-ketoglutaric acid through the action of 2-hydroxyglutarate dehydrogenase (HGDH). Humans have to variants of this enzyme: D-2-hydroxyglutarate dehydrogenase (D2HGDH) and L-2-hydroxyglutarate dehydrogenase (L2HGDH). A deficiency in either of these two enzymes can lead to a disease known as 2-hydroxyglutaric aciduria. L-2-hydroxyglutaric aciduria (caused by loss of L2HGDH) is chronic, with early symptoms such as hypotonia, tremors, and epilepsy declining into spongiform leukoencephalopathy, muscular choreodystonia, mental retardation, and psychomotor regression. D-2-hydroxyglutaric aciduria (caused by loss of D2HGDH or gain of function of IDH) is rare, with symptoms including cancer, macrocephaly, cardiomyopathy, mental retardation, hypotonia, and cortical blindness. 2-hydroxyglutarate was the first oncometabolite (or cancer-causing metabolite) to be formally named or identified. In cancer it is either produced by overexpression of phosphoglycerate dehydrogenase (PHGDH) or is produced in excess by gain-of-function mutations in the cytosolic and mitochondrial isoforms of isocitrate dehydrogenase (IDH). IDH is part of TCA cycle and is generated in high abundance when IDH is mutated. 2-hydroxyglutarate is sufficiently similar in structure to 2-oxogluratate (2OG) that it is able to inhibit a range of 2OG-dependent dioxygenases, including histone lysine demethylases (KDMs) and members of the ten-eleven translocation (TET) family of 5-methylcytosine (5mC) hydroxylases. This inhibitory effect leads to alterations in the hypoxia induced factor (HIF)-mediated hypoxic response and alterations in gene expression through global epigenetic remodeling. The net effect is that 2-hydroxyglutarate causes a cascading effect that leads genetic perturbations and malignant transformation. Furthermore, 2-hydroxyglutarate is found to be associated with glutaric aciduria II, which is also an inborn error of metabolism. 2-Hydroxyglutarate has also been found to be a metabolite in Aspergillus (PMID: 6057807).

Glycerophosphoric acid
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 brain and skeletal muscle cells of mammals (wikipedia). [HMDB]

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).

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. The acyl radical is histidyl. relative retention time with respect to 9-anthracene Carboxylic Acid is 0.046 relative retention time with respect to 9-anthracene Carboxylic Acid is 0.045 relative retention time with respect to 9-anthracene Carboxylic Acid is 0.043 L-Histidine is an essential amino acid for infants.

4-Hydroxyphenylpyruvic acid
A 2-oxo monocarboxylic acid that is pyruvic acid in which one of the methyl hydrogens is substituted by a 4-hydroxyphenyl group. 4-Hydroxyphenylpyruvic acid (4-HPPA) is a keto acid. It is a product of the enzyme (R)-4-hydroxyphenyllactate dehydrogenase [EC 1.1.1.222] and is formed during tyrosine metabolism (KEGG). There are two isomers of HPPA, specifically 4HPPA and 3HPPA, of which 4HPPA is the most common. The enzyme 4-hydroxyphenylpyruvic acid dioxygenase (HPD) catalyzes the reaction of 4-hydroxyphenylpyruvic acid to homogentisic acid in the tyrosine catabolism pathway. A deficiency in the catalytic activity of HPD is known to lead to tyrosinemia type III, an autosomal recessive disorder characterized by elevated levels of blood tyrosine and massive excretion of tyrosine derivatives into urine. It has been shown that hawkinsinuria, an autosomal dominant disorder characterized by the excretion of hawkinsin, may also be a result of HPD deficiency (PMID: 11073718).

Those are prenol lipids structurally characterized by a bile acid or alcohol which bears three hydroxyl groups. Thus, cholic acid is considered to be a bile acid lipid molecule. Cholic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Cholic acid can be found in a number of food items such as cocoa bean, walnut, garden rhubarb, and carob, which makes cholic acid a potential biomarker for the consumption of these food products. Cholic acid can be found primarily in bile, blood, feces, and urine, as well as throughout all human tissues. Cholic acid exists in all living organisms, ranging from bacteria to humans. In humans, cholic acid is involved in few metabolic pathways, which include bile acid biosynthesis, cerebrotendinous xanthomatosis (CTX), congenital bile acid synthesis defect type II, and congenital bile acid synthesis defect type III. Cholic acid is also involved in few metabolic disorders, which include 27-hydroxylase deficiency, familial hypercholanemia (FHCA), and zellweger syndrome. Moreover, cholic acid is found to be associated with biliary atresia, cirrhosis, cystic fibrosis, and primary biliary cirrhosis.
