Ergocalciferol
Ergocalciferol appears as odorless white crystals. Used as a dietary supplement and food additive. (EPA, 1998) Vitamin D2 is a vitamin D supplement and has been isolated from alfalfa. It has a role as a nutraceutical, a bone density conservation agent, a rodenticide and a plant metabolite. It is a seco-ergostane, a hydroxy seco-steroid and a vitamin D. Ergocalciferol is an inactivated vitamin D analog. It is synthesized by some plants in the presence of UVB light. The production of ergocalciferol was prompted by the identification of dietary deficiency, more specifically vitamin D, as the main causative factor for the development of rickets. Ergocalciferol was isolated for the first time from yeast in 1931 and its structure was elucidated in 1932. Ergocalciferol is considered the first vitamin D analog and is differentiated from [cholecalciferol] by the presence of a double bond between C22 and C23 and the presence of a methyl group at C24. These modifications reduce the affinity of ergocalciferol for the vitamin D binding protein resulting in faster clearance, limits its activation, and alters its catabolism. The first approved product containing ergocalciferol under the FDA records was developed by US Pharm Holdings and was FDA approved in 1941. Ergocalciferol is a Provitamin D2 Compound.

Theobromine, or 3,7-Dimethylxanthine, is the principle alkaloid in Theobroma cacao (the cacao bean) and other plants. A xanthine alkaloid that is used as a bronchodilator and as a vasodilator. It has a weaker diuretic activity than theophylline and is also a less powerful stimulant of smooth muscle. It has practically no stimulant effect on the central nervous system. It was formerly used as a diuretic and in the treatment of angina pectoris and hypertension. Theobromine is a bitter alkaloid of the methylxanthine family, which also includes the similar compounds theophylline and caffeine. Despite its name, the compound contains no bromine. Theobromine is derived from Theobroma, the genus of the cacao tree, which is composed of the Greek roots theo ("God") and broma ("food"), meaning "food of the gods". It is the primary alkaloid found in cocoa and chocolate, and is one of the causes for chocolates mood-elevating effects. The amount found in chocolate is small enough that chocolate can be safely consumed by humans in large quantities, but animals that metabolize theobromine more slowly, such as cats and dogs, can easily consume enough chocolate to cause chocolate poisoning. Theobromine is a stimulant frequently confused with caffeine. Theobromine has very different effects on the human body from caffeine; it is a mild, lasting stimulant with a mood improving effect, whereas caffeine has a strong, immediate effect and increases stress. In medicine, it is used as a diuretic, vasodilator, and myocardial stimulant. There is a possible association between prostate cancer and theobromine.

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

beta-Cryptoxanthin
beta-Cryptoxanthin has been isolated from abalone, fish eggs, and many higher plants. beta-Cryptoxanthin is a major source of vitamin A, often second only to beta-carotene, and is present in fruits such as oranges, tangerines, and papayas (PMID: 8554331). Frequent intake of tropical fruits that are rich in beta-cryptoxanthin is associated with higher plasma beta-cryptoxanthin concentrations in Costa Rican adolescents. Papaya intake was the best food predictor of plasma beta-cryptoxanthin concentrations. Subjects that frequently consumed (i.e. greater or equal to 3 times/day) tropical fruits with at least 50 micro g/100 g beta-cryptoxanthin (e.g. papaya, tangerine, orange, watermelon) had twofold the plasma beta-cryptoxanthin concentrations of those with intakes of less than 4 times/week (PMID: 12368412). A modest increase in beta-cryptoxanthin intake, equivalent to one glass of freshly squeezed orange juice per day, is associated with a reduced risk of developing inflammatory disorders such as rheumatoid arthritis (PMID: 16087992). Higher prediagnostic serum levels of total carotenoids and beta-cryptoxanthin were associated with lower smoking-related lung cancer risk in middle-aged and older men in Shanghai, China (PMID: 11440962). Consistent with inhibition of the lung cancer cell growth, beta-cryptoxanthin induced the mRNA levels of retinoic acid receptor beta (RAR-beta) in BEAS-2B cells, although this effect was less pronounced in A549 cells. Furthermore, beta-cryptoxanthin transactivated the RAR-mediated transcription activity of the retinoic acid response element. These findings suggest a mechanism of anti-proliferative action of beta-cryptoxanthin and indicate that beta-cryptoxanthin may be a promising chemopreventive agent against lung cancer (PMID: 16841329). Cryptoxanthin is a natural carotenoid pigment. It has been isolated from a variety of sources including the petals and flowers of plants in the genus Physalis, orange rind, papaya, egg yolk, butter, apples, and bovine blood serum. In a pure form, cryptoxanthin is a red crystalline solid with a metallic lustre. It is freely soluble in chloroform, benzene, pyridine, and carbon disulfide. In the human body, cryptoxanthin is converted into vitamin A (retinol) and is therefore considered a provitamin A. As with other carotenoids, cryptoxanthin is an antioxidant and may help prevent free radical damage to cells and DNA, as well as stimulate the repair of oxidative damage to DNA. Structurally, cryptoxanthin is closely related to beta-carotene, with only the addition of a hydroxyl group. It is a member of the class of carotenoids known as xanthophylls. Beta-cryptoxanthin is a carotenol that exhibits antioxidant activity. It has been isolated from fruits such as papaya and oranges.

Zeaxanthin
Zeaxanthin is a carotenoid xanthophyll and is one of the most common carotenoid found in nature. It is the pigment that gives corn, saffron, and many other plants their characteristic color. Zeaxanthin breaks down to form picrocrocin and safranal, which are responsible for the taste and aroma of saffron Carotenoids are among the most common pigments in nature and are natural lipid soluble antioxidants. Zeaxanthin is one of the two carotenoids (the other is lutein) that accumulate in the eye lens and macular region of the retina with concentrations in the macula greater than those found in plasma and other tissues. Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. The main difference between them is in the location of a double bond in one of the end rings. This difference gives lutein three chiral centers whereas zeaxanthin has two. A relationship between macular pigment optical density, a marker of lutein and zeaxanthin concentration in the macula, and lens optical density, an antecedent of cataractous changes, has been suggested. The xanthophylls may act to protect the eye from ultraviolet phototoxicity via quenching reactive oxygen species and/or other mechanisms. Some observational studies have shown that generous intakes of lutein and zeaxanthin, particularly from certain xanthophyll-rich foods like spinach, broccoli and eggs, are associated with a significant reduction in the risk for cataract (up to 20\\%) and for age-related macular degeneration (up to 40\\%). While the pathophysiology of cataract and age-related macular degeneration is complex and contains both environmental and genetic components, research studies suggest dietary factors including antioxidant vitamins and xanthophylls may contribute to a reduction in the risk of these degenerative eye diseases. Further research is necessary to confirm these observations. (PMID: 11023002). Zeaxanthin has been found to be a microbial metabolite, it can be produced by Algibacter, Aquibacter, Escherichia, Flavobacterium, Formosa, Gramella, Hyunsoonleella, Kordia, Mesoflavibacter, Muricauda, Nubsella, Paracoccus, Siansivirga, Sphingomonas, Zeaxanthinibacter and yeast (https://reader.elsevier.com/reader/sd/pii/S0924224417302571?token=DE6BC6CC7DCDEA6150497AA3E375097A00F8E0C12AE03A8E420D85D1AC8855E62103143B5AE0B57E9C5828671F226801). It is a marker for the activity of Bacillus subtilis and/or Pseudomonas aeruginosa in the intestine. Higher levels are associated with higher levels of Bacillus or Pseudomonas. (PMID: 17555270; PMID: 12147474) Zeaxanthin is a carotenol. It has a role as a bacterial metabolite, a cofactor and an antioxidant. It derives from a hydride of a beta-carotene.

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

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

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

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

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

Deoxyuridine
Deoxyuridine, also known as dU, belongs to the class of organic compounds known as pyrimidine 2-deoxyribonucleosides. Pyrimidine 2-deoxyribonucleosides are compounds consisting of a pyrimidine linked to a ribose which lacks a hydroxyl group at position 2. It is similar in chemical structure to uridine, but without the 2-hydroxyl group. Deoxyuridine exists in all living organisms, ranging from bacteria to humans. Within humans, deoxyuridine participates in a number of enzymatic reactions. In particular, deoxyuridine can be biosynthesized from deoxycytidine through its interaction with the enzyme cytidine deaminase. In addition, deoxyuridine can be converted into uracil and deoxyribose 1-phosphate through its interaction with the enzyme thymidine phosphorylase. Deoxyuridine is considered to be an antimetabolite that is converted into deoxyuridine triphosphate during DNA synthesis. Laboratory suppression of deoxyuridine is used to diagnose megaloblastic anemia due to vitamin B12 and folate deficiencies. In humans, deoxyuridine is involved in the metabolic disorder called UMP synthase deficiency (orotic aciduria). Outside of the human body, deoxyuridine has been detected, but not quantified in, several different foods, such as lichee, highbush blueberries, agaves, macadamia nut (M. tetraphylla), and red bell peppers. This could make deoxyuridine a potential biomarker for the consumption of these foods. 2-Deoxyuridine is a naturally occurring nucleoside.

3-ureidopropionate
Ureidopropionic acid, also known as 3-ureidopropanoate or N-carbamoyl-beta-alanine, belongs to the class of organic compounds known as ureas. Ureas are compounds containing two amine groups joined by a carbonyl (C=O) functional group. Ureidopropionic acid is an intermediate in the metabolism of uracil. More specifically, it is a breakdown product of dihydrouracil and is produced by the enzyme dihydropyrimidase. It is further decomposed into beta-alanine via the enzyme beta-ureidopropionase. Ureidopropionic acid is essentially a urea derivative of beta-alanine. High levels of ureidopropionic acid are found in individuals with beta-ureidopropionase (UP) deficiency (PMID: 11675655). Enzyme deficiencies in pyrimidine metabolism are associated with a risk for severe toxicity against the antineoplastic agent 5-fluorouracil. Ureidopropionic acid has been detected, but not quantified in, several different foods, such as gram beans, broccoli, climbing beans, oriental wheat, and mandarin orange (clementine, tangerine).

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

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

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

Debrisoquine
Debrisoquine is an adrenergic neuron-blocking drug. Genetic and environmental factors are determinants of the interindividual and interethnic variability in drug metabolism. Thus, interethnic differences in debrisoquine hydroxylation polymorphism (Cytochrome p450, subfamily IID, polypeptide 6, CYP2D6) might be partly responsible for the variation in haloperidol disposition between races. The influence of tobacco, ethanol, caffeine, gender, and oral contraceptive use on the debrisoquine metabolic ratio (MR) has been analyzed in panels of healthy volunteers. About 5-10\\% of European white population has a genetically determinant defect of the CYP2D6, one of the enzymes of cytochrome P-450. This defect leads to the impaired metabolism of many drugs including various psychopharmacological agents. The measurement of the hydroxylation of debrisoquine is a laboratory test which allows identifying such an individual. Patients who show an impaired hydroxylation of debrisoquine usually demonstrate severe side effects and poor outcome of psychopharmacotherapy. In practice, knowledge of a patients debrisoquine metabolic phenotype is an advantage when prescribing tricyclic antidepressants and neuroleptics, as the drug concentration will be considerably higher in slow metabolisers than in the average patient.

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

L-Histidinol, a structural analogue of the essential amino acid L-histidine, enhances the toxicity of a variety of anticancer drugs for many tumour cells of animal origin (PMID:8297120). L-Histidinol inhibits human myristoyl-CoA:protein-myristoyltransferase (hNMT), an essential eukaryotic enzyme that catalyzes the cotranslational transfer of myristate into the NH2-terminal glycine residue of a number of important proteins of diverse function (PMID:9778369).

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

Nα-Acetyl-L-lysine
N-epsilon-Acetyl-L-lysine also known as Nepsilon-Acetyllysine or N6-Acetyllysine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at one of its nitrogen atoms. N-epsilon-Acetyl-L-lysine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-epsilon-Acetyl-L-lysine is a biologically available sidechain, N-capped form of the proteinogenic alpha amino acid L-lysine. Unlike L-lysine, acetylated lysine derivatives such as N-epsilon-Acetyl-L-lysine are zwitterionic compounds. These are molecules that contains an equal number of positively- and negatively-charged functional groups. N-epsilon-Acetyl-L-lysine is found naturally in eukaryotes ranging from yeast to plants to humans. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins (often histones) by specific hydrolases. N-epsilon-Acetyl-L-lysine can be biosynthesized from L-lysine and acetyl-CoA via the enzyme known as Lysine N-acetyltransferase. Post-translational lysine-acetylation is one of two major modifications of lysine residues in various proteins – either N-terminal or N-alpha acetylation or N6 (sidechain) acetylation. Side-chain acetylation of specific lysine residues in the N-terminal domains of core histones is a biochemical marker of active genes. Acetylation is now known to play a major role in eukaryotic transcription. Specifically, acetyltransferase enzymes that act on particular lysine side chains of histones and other proteins are intimately involved in transcriptional activation. By modifying chromatin proteins and transcription-related factors, these acetylases are believed to regulate the transcription of many genes. The best-characterized mechanism is acetylation, catalyzed by histone acetyltransferase (HAT) enzymes. HATs function enzymatically by transferring an acetyl group from acetyl-coenzyme A (acetyl-CoA) to the amino group of certain lysine side chains within a histones basic N-terminal tail region. Within a histone octamer, these regions extend out from the associated globular domains, and in the context of a nucleosome, they are believed to bind the DNA through charge interactions (positively charged histone tails associated with negatively charged DNA) or mediate interactions between nucleosomes. Lysine acetylation, which neutralizes part of a tail regions positive charge, is postulated to weaken histone-DNA or nucleosome-nucleosome interactions and/or signal a conformational change, thereby destabilizing nucleosome structure or arrangement and giving other nuclear factors, such as the transcription complex, more access to a genetic locus. In agreement with this is the fact that acetylated chromatin has long been associated with states of transcriptional activation. Specific recognition of N6-acetyl-L-lysine is a conserved function of all bromodomains found in different proteins, recognized as an emerging intracellular signalling mechanism that plays critical roles in regulating gene transcription, cell-cycle progression, apoptosis, DNA repair, and cytoskeletal organization (PMID: 9169194 , 10827952 , 17340003 , 16247734 , 9478947 , 10839822 ). N-acetylated amino acids, such as N-epsilon-Acetyl-L-lysine can be released by an N-acylpeptide hydrolase from histones going through proteolytic degradation (PMID: 16465618). Many N-acetylamino acids are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). Isolated from sugarbeet (Beta vulgaris) KEIO_ID A174 Nepsilon-Acetyl-L-lysine is a derivative of the amino acid lysine.
Prednisone
Prednisone is only found in individuals that have used or taken this drug. It is a synthetic anti-inflammatory glucocorticoid derived from cortisone. It is biologically inert and converted to prednisolone in the liver. [PubChem]Prednisone is a glucocorticoid receptor agonist. It is first metabolized in the liver to its active form, prednisolone. Prednisolone crosses cell membranes and binds with high affinity to specific cytoplasmic receptors. The result includes inhibition of leukocyte infiltration at the site of inflammation, interference in the function of mediators of inflammatory response, suppression of humoral immune responses, and reduction in edema or scar tissue. The antiinflammatory actions of corticosteroids are thought to involve phospholipase A2 inhibitory proteins, lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes.

Stanozolol
Stanozolol is only found in individuals that have used or taken this drug. Stanozolol has is a synthetic anabolic steroid with therapeutic uses in treating hereditary angioedema. Stanozolol was first synthesized by Clinton et al. in 1959, as a heterocyclic anabolic androgenic steroid. The structure of Stanozolol differs from endogenous steroid hormones and most commercially available anabolic steroids. It most closely resembles methyl testosterone. Instead of the 3-ketogroup in methyltestosterone, there is a pyrazole ring fused to the androstane ring system. This slightly different structure has the disadvantage of making extraction and isolation of the molecule from matrices more difficult. Like most other anabolic steroids, Stanozolol has poor gas chromatographic behavior and is difficult to detect in urine, because of renal clearance and low urinary excretion. This is due to the rapid metabolization, leading to low concentration levels of the parent compound found in urine. Therefore, most research studies had focused on the detection of urinary metabolites. Androgens are drugs, derived from the natural male sex hormone testosterone, with high anabolic potential and minimized androgenic activity. It has been abused by several high profile professional athletes. Stanozolol binds to androgen receptors, such as membrane bound receptor proteins LAGS and stanozolol-binding protein (STBP). Anabolic steroids stimulate protein synthesis, resulting in an acceleration of the food conversion rate and increasing muscle growth, body mass and enhanced performance. Androgens can be used as therapeutics, because they accelerate the recovery of protein deficiency and protein-wasting disorders (e.g. osteoporosis), but they are also widely abused in doping, as well in animals as in men.

N-Acetylarylamine
N-Acetylarylamine is an odourless solid chemical of leaf or flake-like appearance. It is also known as acetanilide, N-phenylacetamide, acetanil, or acetanilid, and was formerly known by the trade name Antifebrin. N-Acetylarylamine has analgesic and fever-reducing properties; it is in the same class of drugs as acetaminophen (paracetamol). Under the name acetanilid it formerly figured in the formula of a number of patent medicines and over the counter drugs. In 1948, Julius Axelrod and Bernard Brodie discovered that acetanilide is much more toxic in these applications than other drugs, causing methemoglobinemia and ultimately doing damage to the liver and kidneys. As such, acetanilide has largely been replaced by less toxic drugs, in particular acetaminophen, which is a metabolite of acetanilide and whose use Axelrod and Brodie suggested in the same study.

Ephedrine
Ephedrine is only found in individuals who have consumed this drug. Ephedrine is an alpha- and beta-adrenergic agonist that may also enhance release of norepinephrine. It has been used in the treatment of several disorders including asthma, heart failure, rhinitis, and urinary incontinence, and for its central nervous system stimulatory effects in the treatment of narcolepsy and depression. It has become less extensively used with the advent of more selective agonists. [PubChem] Ephedrine is similar in molecular structure to the well-known drugs phenylpropanolamine and methamphetamine, as well as to the important neurotransmitter epinephrine (adrenalin). Chemically, it is an alkaloid with a phenethylamine skeleton found in various plants in the genus Ephedra (family Ephedraceae).

Levetiracetam
Levetiracetam is an anticonvulsant medication used to treat epilepsy. Levetiracetam may selectively prevent hypersynchronization of epileptiform burst firing and propagation of seizure activity. Levetiracetam binds to the synaptic vesicle protein SV2A, which is thought to be involved in the regulation of vesicle exocytosis. Although the molecular significance of levetiracetam binding to synaptic vesicle protein SV2A is not understood, levetiracetam and related analogs showed a rank order of affinity for SV2A which correlated with the potency of their antiseizure activity in audiogenic seizure-prone mice.

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

Medroxyprogesterone
Medroxyprogesterone, or MP is a progestin (synthetic progestogen). MP is not used medically, as it is over two orders of magnitude less potent than medroxyprogesterone acetate (MPA); a derivative of MP (PMID: 16784762). MP may be formed via the metabolism of MPA. Medroxyprogesterone acetate is used to treat conditions such as absent or irregular menstrual periods, or abnormal uterine bleeding. Synthetic progestogens are widely used to simulate the effects of progesterone; a natural female sex hormone. Progesterone is essential for endometrial receptivity, embryo implantation, and the successful establishment of pregnancy. A low progesterone concentration or an insufficient response to progesterone can cause infertility and pregnancy loss (PMID: 20104424). In addition to progestagenic activity, MP is also a weak antiandrogen in vitro (PMID: 29990947). Medroxyprogesterone is only found in individuals that have used or taken MPA.

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).

Orotidylic acid
Orotidylic acid, also known as 5-(dihydrogen phosphate)orotidine or omp, is a member of the class of compounds known as pyrimidine ribonucleoside monophosphates. Pyrimidine ribonucleoside monophosphates are pyrimidine ribobucleotides with monophosphate group linked to the ribose moiety. Orotidylic acid is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Orotidylic acid can be found in a number of food items such as coriander, summer savory, oriental wheat, and sourdough, which makes orotidylic acid a potential biomarker for the consumption of these food products. Orotidylic acid can be found primarily in prostate Tissue, as well as in human prostate tissue. Orotidylic acid exists in all living species, ranging from bacteria to humans. In humans, orotidylic acid is involved in a couple of metabolic pathways, which include glycine and serine metabolism and pyrimidine metabolism. Orotidylic acid is also involved in several metabolic disorders, some of which include dihydropyrimidinase deficiency, dihydropyrimidine dehydrogenase deficiency (DHPD), 3-phosphoglycerate dehydrogenase deficiency, and non ketotic hyperglycinemia. Moreover, orotidylic acid is found to be associated with prostate cancer. Orotidylic acid (OMP), is a pyrimidine nucleotide which is the last intermediate in the biosynthesis of uridine monophosphate. Decarboxylation by Orotidylate decarboxylase affords Uridine 5-phosphate which is the route to Uridine and its derivatives de novo and consequently one of the most important processes in nucleic acid synthesis (Dictionary of Organic Compounds). In humans, the enzyme UMP synthase converts OMP into uridine 5- monophosphate. If UMP synthase is defective, orotic aciduria can result. (Wikipedia). KEIO_ID O015; [MS2] KO009132 KEIO_ID O015
Uridine 5'-monophosphate
Uridine 5-monophosphate (UMP), also known as uridylic acid or uridylate, belongs to the class of organic compounds known as pyrimidine ribonucleoside monophosphates. These are pyrimidine ribobucleotides with monophosphate group linked to the ribose moiety. UMP consists of a phosphate group, a pentose sugar ribose, and the nucleobase uracil; hence, it is a ribonucleotide monophosphate. Uridine 5-monophosphate exists in all living species, ranging from bacteria to plants to humans. UMP is a nucleotide that is primarily used as a monomer in RNA biosynthesis. Uridine monophosphate is formed from Orotidine 5-monophosphate (orotidylic acid) in a decarboxylation reaction catalyzed by the enzyme orotidylate decarboxylase. Within humans, uridine 5-monophosphate participates in a number of enzymatic reactions. In particular, uridine 5-monophosphate can be converted into uridine 5-diphosphate through the action of the enzyme UMP-CMP kinase. In addition, uridine 5-monophosphate can be biosynthesized from uridine 5-diphosphate through its interaction with the enzyme soluble calcium-activated nucleotidase 1. In brain research studies, uridine monophosphate has been used as a convenient delivery compound for uridine. Uridine is present in many foods, mainly in the form of RNA. Non-phosphorylated uridine is not bioavailable beyond first-pass metabolism. In a study, gerbils fed a combination of uridine monophosphate, choline, and docosahexaenoic acid (DHA) were found to have significantly improved performance in running mazes over those not fed the supplements, implying an increase in cognitive function (PMID: 18606862). 5′-UMP.

Arachidate (20:0)
Arachidic acid, also known as icosanoic acid, is a saturated fatty acid with a 20-carbon chain. It is a minor constituent of butter, perilla oil, peanut oil, corn oil, and cocoa butter. It also constitutes 7.08\\\\% of the fats from the fruit of the durian species Durio graveolens. The salts and esters of arachidic acid are known as arachidates. Its name derives from the Latin arachis that means peanut. It can be formed by the hydrogenation of arachidonic acid. The reduction of arachidic acid yields arachidyl alcohol. Arachidic acid is used for the production of detergents, photographic materials and lubricants. Arachidic acid belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Arachidic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Arachidonic acid (Icosanoic acid), a long-chain fatty acid, is present in all mammalian cells, typically esterified to membrane phospholipids, and is one of the most abundant polyunsaturated fatty acids present in human tissue[1][2].

Phosphoethanolamine
O-Phosphoethanolamine, also known as PEA, phosphorylethanolamine, colamine phosphoric acid or ethanolamine O-phosphate, belongs to the class of organic compounds known as phosphoethanolamines. Phosphoethanolamines are compounds containing a phosphate linked to the second carbon of an ethanolamine. O-Phosphoethanolamine is used in the biosynthesis of two different types of phospholipids: glycerophospholipids and sphingolipids. O-Phosphoethanolamine exists in all living species, ranging from bacteria to plants to humans. Within humans, O-phosphoethanolamine participates in a number of enzymatic reactions. In particular, cytidine triphosphate and O-phosphoethanolamine can be converted into CDP-ethanolamine; which is mediated by the enzyme ethanolamine-phosphate cytidylyltransferase. In addition, O-phosphoethanolamine can be biosynthesized from ethanolamine; which is catalyzed by the enzyme choline/ethanolamine kinase. In humans, O-phosphoethanolamine is involved in phosphatidylcholine biosynthesis. O-phosphoethanolamine is also a product of the metabolism of sphingolipids. In particular, sphinglipids are metabolized in vivo to phosphorylethanolamine and a fatty aldehyde, generally palmitaldehyde. Both metabolites are ultimately converted to glycerophospholipids. The lipids are first phosphorylated by a kinase and then cleaved by the pyridoxal-dependent sphinganine-1-phosphate aldolase. Elevated urine levels of O-Phosphoethanolamine or PEA can be used to help in the diagnosis of Hypophosphatasia (HPP). Reference ranges for urinary PEA vary according to age and somewhat by diet, and follow a circadian rhythm. Outside of the human body, O-phosphoethanolamine has been detected, but not quantified in, several different foods, such as oxheart cabbages, anises, shiitakes, abalones, and teffs. Phosphoryl-ethanolamine, also known as colamine phosphoric acid or ethanolamine phosphate, is a member of the class of compounds known as phosphoethanolamines.

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.

alpha-D-Glucose 1,6-bisphosphate
Glucose 1,6-diphosphate (G-1,6-P2) is considered to be a major regulator of carbohydrate metabolism. It has been demonstrated that G-1,6-P2 is a potent activator (deinhibitor) of skeletal muscle phosphofructokinase (PFK) and phosphoglucomutase, while being an inhibitor of hexokinase (see Ref. 2). In addition, G-1,6-P2 has been shown to inhibit 6-phosphogluconate dehydrogenase in various rat tissues and fructose 1,6-bisphosphatase in bovine liver. Various factors and conditions affect the tissue content of G-1,6-P2. Specifically, anoxia induces a rapid fall in the content of G-l,6-P2 in the brain. Glucose 1,6-diphosphate has been recognized as a regulatory signal implicated in the control of metabolism, oxygen affinity of red cells, and other cellular functions. The levels of G 1,6-P2 are reduced in the liver and in the muscle of rats with experimentally induced diabetes. In muscle of genetically dystrophic mice, a decrease in the levels of G 1,6-P2 has been found, probably resulting from enhancement of glucose 1,6-P2 phosphatase activity. G 1,6-P2 is an inhibitor of hexokinase and its level is increased significantly after 5 min of exercise (~25\\%) and then decreased continuously. G 1,6-P2 is a potent allosteric activator of phosphofructokinase, and is markedly decreased in muscles of patients with glycogenosis type VII (muscle phosphofructokinase deficiency) and type V (muscle phosphorylase deficiency). Chronic alcohol intake produces an increase in the concentration of G 1,6-P2 in human muscle before the first sign of myopathy appears. When myopathy is present the level decreases to be similar to healthy humans. These changes could contribute to the decline in skeletal muscle performance (PMID:1449560, 2018547, 2003594, 3407759).

Thioguanine
Thioguanine is only found in individuals that have used or taken this drug. It is an antineoplastic compound which also has antimetabolite action. The drug is used in the therapy of acute leukemia. [PubChem]Thioguanine competes with hypoxanthine and guanine for the enzyme hypoxanthine-guanine phosphoribosyltransferase (HGPRTase) and is itself converted to 6-thioguanilyic acid (TGMP), which reaches high intracellular concentrations at therapeutic doses. TGMP interferes with the synthesis of guanine nucleotides by its inhibition of purine biosynthesis by pseudofeedback inhibition of glutamine-5-phosphoribosylpyrophosphate amidotransferase, the first enzyme unique to the de novo pathway of purine ribonucleotide synthesis. TGMP also inhibits the conversion of inosinic acid (IMP) to xanthylic acid (XMP) by competition for the enzyme IMP dehydrogenase. Thioguanine nucleotides are incorporated into both the DNA and the RNA by phosphodiester linkages, and some studies have shown that incorporation of such false bases contributes to the cytotoxicity of thioguanine. Its tumor inhibitory properties may be due to one or more of its effects on feedback inhibition of de novo purine synthesis; inhibition of purine nucleotide interconversions; or incorporation into the DNA and RNA. The overall result of its action is a sequential blockade of the utilization and synthesis of the purine nucleotides.

Bendroflumethiazide
Bendroflumethiazide is only found in individuals that have used or taken this drug. It is a thiazide diuretic with actions and uses similar to those of hydrochlorothiazide. It has been used in the treatment of familial hyperkalemia, hypertension, edema, and urinary tract disorders. (From Martindale, The Extra Pharmacopoeia, 30th ed, p810)As a diuretic, bendroflumethiazide inhibits active chloride reabsorption at the early distal tubule via the Na-Cl cotransporter, resulting in an increase in the excretion of sodium, chloride, and water. Thiazides like bendroflumethiazide also inhibit sodium ion transport across the renal tubular epithelium through binding to the thiazide sensitive sodium-chloride transporter. This results in an increase in potassium excretion via the sodium-potassium exchange mechanism. The antihypertensive mechanism of bendroflumethiazide is less well understood although it may be mediated through its action on carbonic anhydrases in the smooth muscle or through its action on the large-conductance calcium-activated potassium (KCa) channel, also found in the smooth muscle.

Repaglinide
Repaglinide is an oral antihyperglycemic agent used for the treatment of non-insulin-dependent diabetes mellitus (NIDDM). It belongs to the meglitinide class of short-acting insulin secretagogues, which act by binding to cells of the pancreas to stimulate insulin release. Repaglinide induces an early insulin response to meals decreasing postprandial blood glucose levels. It should only be taken with meals and meal-time doses should be skipped with any skipped meal. Approximately one month of therapy is required before a decrease in fasting blood glucose is seen. Meglitnides may have a neutral effect on weight or cause a slight increase in weight. The average weight gain caused by meglitinides appears to be lower than that caused by sulfonylureas and insulin and appears to occur only in those naive to oral antidiabetic agents. Due to their mechanism of action, meglitinides may cause hypoglycemia although the risk is thought to be lower than that of sulfonylureas since their action is dependent on the presence of glucose. In addition to reducing postprandial and fasting blood glucose, meglitnides have been shown to decrease glycosylated hemoglobin (HbA1c) levels, which are reflective of the last 8-10 weeks of glucose control. Meglitinides appear to be more effective at lowering postprandial blood glucose than metformin, sulfonylureas and thiazolidinediones. Repaglinide is extensively metabolized in the liver and excreted in bile. Repaglinide metabolites do not possess appreciable hypoglycemic activity. Approximately 90\\% of a single orally administered dose is eliminated in feces and 8\\% in urine.

Aspartame
Aspartame is the name for an artificial, non-carbohydrate sweetener, aspartyl-phenylalanine-1-methyl ester; i.e., the methyl ester of the dipeptide of the amino acids aspartic acid and phenylalanine. It is marketed under a number of trademark names, such as Equal, and Canderel, and is an ingredient of approximately 6,000 consumer foods and beverages sold worldwide. It is commonly used in diet soft drinks, and is often provided as a table condiment. It is also used in some brands of chewable vitamin supplements. In the European Union, it is also known under the E number (additive code) E951. Aspartame is also one of the sugar substitutes used by diabetics. Upon ingestion, aspartame breaks down into several constituent chemicals, including the naturally-occurring essential amino acid phenylalanine which is a health hazard to the few people born with phenylketonuria, a congenital inability to process phenylalanine. Aspartic acid is an amino acid commonly found in foods. Approximately 40\\\% of aspartame (by mass) is broken down into aspartic acid. Because aspartame is metabolized and absorbed very quickly (unlike aspartic acid-containing proteins in foods), it is known that aspartame could spike blood plasma levels of aspartate. Aspartic acid is in a class of chemicals known as excitotoxins. Abnormally high levels of excitotoxins have been shown in hundreds of animals studies to cause damage to areas of the brain unprotected by the blood-brain barrier and a variety of chronic diseases arising out of this neurotoxicity.

Hexadecanedioic acid
Hexadecanedioic acid, also known as thapsic acid, belongs to the class of organic compounds known as long-chain fatty acids.

Cephapirin
Cephapirin is an injectable, first-generation cephalosporin antibiotic that has a wide spectrum of activity against gram-positive and gram-negative organisms. The bactericidal activity of cephapirin results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs). Cephapirin is more resistant to beta-lactamases than the penicillins, and therefore is effective against staphylococci, with the exception of methicillin-resistant staphylococci. Cephapirin is FDA approved for use in food-producing animals, especially dairy cattle. Cephapirin is used for the treatment of mastitis in cows. Production for use in humans has been discontinued in the United States. It is marketed under the trade name Cefadyl. Active against gram-positive and -negative bacteria (vet. use). FDA approved for use in food producing animals, especies dairy cattle.

UDP-α-D-N-Acetylglucosamine disodium
Uridine diphosphate-N-acetylglucosamine (uridine 5-diphosphate-GlcNAc, or UDP-Glc-NAc) is an acetylated aminosugar nucleotide. UDP-GlcNAc is the donor substrate for modification of nucleocytoplasmic proteins at serine and threonine residues with N-acetylglucosamine (O-GlcNAc). Nutrient sensing in mammals is done through the hexosamine biosynthetic pathway (HSP), which produces uridine 5-diphospho-N-acetylglucosamine (UDP-Glc-NAc) as its end product. Mammals respond to nutrient excess by activating O-GlcNAcylation (addition of O-linked N-acetylglucosamine). O-GlcNAc addition (and removal) is key to histone remodeling, transcription, proliferation, apoptosis, and proteasomal degradation. This nutrient-responsive signaling pathway also modulates important cellular pathways, including the insulin signaling cascade in. Alterations in O-GlcNAc metabolism are associated with various human diseases including diabetes mellitus and neurodegeneration. (PMID: 16317114) Due to the chemical makeup of UDP-GlcNAc, it is well positioned to serve as a glucose sensor in that it is a high-energy compound that requires and/or responds to glucose, amino acid, fatty acid and nucleotide metabolism for synthesis. Elevated levels of O-GlcNAc have an effect on insulin-stimulated glucose uptake. (PMID: 12678487).

Clomifene
Clomifene is only found in individuals that have used or taken this drug. It is a triphenyl ethylene stilbene derivative which is an estrogen agonist or antagonist depending on the target tissue. [PubChem]Clomifene has both estrogenic and anti-estrogenic properties, but its precise mechanism of action has not been determined. Clomifene appears to stumulate the release of gonadotropins, follicle-stimulating hormone (FSH), and leuteinizing hormone (LH), which leads to the development and maturation of ovarian follicle, ovulation, and subsequent development and function of the coprus luteum, thus resulting in pregnancy. Gonadotropin release may result from direct stimulation of the hypothalamic-pituitary axis or from a decreased inhibitory influence of estrogens on the hypothalamic-pituitary axis by competing with the endogenous estrogens of the uterus, pituitary, or hypothalamus. Clomifene has no apparent progestational, androgenic, or antrandrogenic effects and does not appear to interfere with pituitary-adrenal or pituitary-thyroid function.

Nateglinide
Nateglinide is an oral antihyperglycemic agent used for the treatment of non-insulin-dependent diabetes mellitus (NIDDM). It belongs to the meglitinide class of short-acting insulin secretagogues, which act by binding to cells of the pancreas to stimulate insulin release. Nateglinide is an amino acid derivative that induces an early insulin response to meals decreasing postprandial blood glucose levels. It should only be taken with meals and meal-time doses should be skipped with any skipped meal. Approximately one month of therapy is required before a decrease in fasting blood glucose is seen. Meglitnides may have a neutral effect on weight or cause a slight increase in weight. The average weight gain caused by meglitinides appears to be lower than that caused by sulfonylureas and insulin and appears to occur only in those naive to oral antidiabetic agents. Due to their mechanism of action, meglitinides may cause hypoglycemia although the risk is thought to be lower than that of sulfonylureas since their action is dependent on the presence of glucose. In addition to reducing postprandial and fasting blood glucose, meglitnides have been shown to decrease glycosylated hemoglobin (HbA1c) levels, which are reflective of the last 8-10 weeks of glucose control. Meglitinides appear to be more effective at lowering postprandial blood glucose than metformin, sulfonylureas and thiazolidinediones. Nateglinide is extensively metabolized in the liver and excreted in urine (83\\%) and feces (10\\%). The major metabolites possess less activity than the parent compound. One minor metabolite, the isoprene, has the same potency as its parent compound.

Zonisamide is a sulfonamide anticonvulsant approved for use as an adjunctive therapy in adults with partial-onset seizures. Zonisamide may be a carbonic anhydrase inhibitor although this is not one of the primary mechanisms of action. Zonisamide may act by blocking repetitive firing of voltage-gated sodium channels leading to a reduction of T-type calcium channel currents, or by binding allosterically to GABA receptors. This latter action may inhibit the uptake of the inhibitory neurotransmitter GABA while enhancing the uptake of the excitatory neurotransmitter glutamate.

Bovinic acid
Bovinic acid is a conjugated linoleic acid, present in human adipose tissue; the amount of bovinic acid in humans is significantly related to milk fat intake. Conjugated linoleic acids (CLAs) are a group of naturally occurring fatty acids present mainly in fats from ruminants. Milk contains over 20 isomers of CLA but the predominant one is cis-9,trans-11-CLA (bovinic acid). Biomedical studies with animal models have shown that this isomer has anticarcinogenic and anti-atherogenic activities. Bovinic acid is produced as an intermediate in the rumen biohydrogenation of linoleic acid but not of linolenic acid. However, it is only a transient intermediate, and the major source of milk fat CLA is from endogenous synthesis (PMID: 10393134, 15736916).

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.

Delta-Tocopherol
Tocopherol, or Vitamin E, is a fat-soluble vitamin in eight forms that is an important antioxidant. Vitamin E is often used in skin creams and lotions because it is believed to play a role in encouraging skin healing and reducing scarring after injuries such as burns. -- Wikipedia; Natural vitamin E exists in eight different forms or isomers, four tocopherols and four tocotrienols. All isomers have a chromanol ring, with a hydroxyl group which can donate a hydrogen atom to reduce free radicals and a hydrophobic side chain which allows for penetration into biological membranes. There is an alpha, beta, gamma and delta form of both the tocopherols and tocotrienols, determined by the number of methyl groups on the chromanol ring. Each form has its own biological activity, the measure of potency or functional use in the body. -- Wikipedia; Alpha-tocopherol is traditionally recognized as the most active form of vitamin E in humans, and is a powerful biological antioxidant. The measurement of "vitamin E" activity in international units (IU) was based on fertility enhancement by the prevention of spontaneous abortions in pregnant rats relative to alpha tocopherol. It increases naturally to about 150\\\\\% of normal in the maternal circulation during human pregnancies. 1 IU of vitamin E is defined as the biological equivalent of 0.667 milligrams of d-alpha-tocopherol, or of 1 milligram of dl-alpha-tocopherol acetate. The other isomers are slowly being recognized as research begins to elucidate their additional roles in the human body. Many naturopathic and orthomolecular medicine advocates suggest that vitamin E supplements contain at least 20\\\\\% by weight of the other natural vitamin E isomers. Commercially available blends of natural vitamin E include "mixed tocopherols" and "high gamma tocopherol" formulas. Also selenium, Coenzyme Q10, and ample vitamin C have been shown to be essential cofactors of natural tocopherols. -- Wikipedia; Synthetic vitamin E, usually marked as d,l-tocopherol or d,l tocopheryl acetate, with 50\\\\\% d-alpha tocopherol moiety and 50\\\\\% l-alpha-tocopherol moiety, as synthesized by an earlier process is now actually manufactured as all-racemic alpha tocopherol, with only about one alpha tocopherol molecule in 8 molecules as actual d-alpha tocpherol. The synthetic form is not as active as the natural alpha tocopherol form. The 1950s thalidomide disaster with numerous severe birth defects is a common example of d- vs l- epimer forms type problem with synthesized racemic mixtures. Information on any side effects of the synthetic vitamin E epimers is not readily available. Naturopathic and orthomolecular medicine advocates have long considered the synthetic vitamin E forms to be with little or no merit for cancer, circulatory and heart diseases. -- Wikipedia; Abetalipoproteinemia is a rare inherited disorder of fat metabolism that results in poor absorption of dietary fat and vitamin E. The vitamin E deficiency associated with this disease causes problems such as poor transmission of nerve impulses, muscle weakness, and degeneration of the retina that can cause blindness. Individuals with abetalipoproteinemia may be prescribed special vitamin E supplements by a physician to treat this disorder. -- Wikipedia; Recent studies also show that vitamin E acts as an effective free radical scavenger and can lower the incidence of lung cancer in smokers. The effects are opposite to that of the clinical trials based on administering carotenoid to male smokers, that resulted in increased risk of lung cancer. Hence vitamin E is an effective antagonist to the oxidative stress that is imposed by high carotenoids in certain patients. -- Wikipedia; A cataract is a condition of clouding of the tissue of the lens of the eye.

Dimethylglycine
Dimethylglycine (DMG) is an amino acid derivative found in the cells of all plants and animals and can be obtained in the diet in small amounts from grains and meat. The human body produces DMG when metabolizing choline into glycine. Dimethylglycine that is not metabolized in the liver is transported by the circulatory system to body tissue. Dimethylglycine was popular with Russian athletes and cosmonauts owing to its reputed ability to increase endurance and reduce fatigue. DMG is also a byproduct of homocysteine metabolism. Homocysteine and betaine are converted to methionine and N,N-dimethylglycine by betaine-homocysteine methyltransferase. DMG in the urine is a biomarker for the consumption of legumes. It is also a microbial metabolite (PMID: 25901889).

Phenylacetylglutamine
Phenylacetylglutamine is a product formed from the conjugation of phenylacetate and glutamine. Technically, it is the amino acid acetylation product of phenylacetate (or phenylbutyrate after beta-oxidation). Phenylacetylglutamine is a normal constituent of human urine, but other mammals such as the dog, cat, rat, monkey, sheep, and horse do not excrete this compound. Phenylacetyl-CoA and L-glutamine react to form phenylacetylglutamine and coenzyme A. The enzyme (glutamine N-acetyl transferase) that catalyzes this reaction has been purified from human liver mitochondria and shown to be a polypeptide species distinct from glycine-N-acyltransferase. Phenylacetylglutamine is a major nitrogenous metabolite that accumulates in uremia (PMID: 2791363, 8972626). It has been shown that over 50\\\% of urine phenylacetylglutamine may be derived from kidney conjugation of free plasma phenylacetic acid and/or from the kidneys preferential filtration of conjugated phenylacetic acid (PMID: 6420430).

Emtricitabine
Emtricitabine is only found in individuals that have used or taken this drug. It is a nucleoside reverse transcriptase inhibitor (NRTI) for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults. Emtricitabine works by inhibiting reverse transcriptase (RT), an enzyme that allows the virus to multiply by copying HIV RNA into new viral DNA. The drug competes with the reverse transcriptases natural substrate deoxycytidine 5-triphosphate and also becomes incorporated into viral DNA. This is a result of emtricitabine being a synthetic nucleoside analogue of cytidine. It is phosphorylated by cellular enzymes to form emtricitabine 5-triphosphate which competes with the natural substrate deoxycytidine 5-triphosphate and becomes incorporated into nascent viral DNA, resulting in early chain termination. By inhibiting HIV-1 reverse transcriptase, emtricitabine can help to lower the amount of HIV (viral load) in a patients body and can indirectly increase the number of immune system cells (T cells or CD4+ T-cells). Both of these changes are associated with healthier immune systems and a decreased likelihood of serious illness. Emtricitabine is always used in conjunction with other HIV medicine to treat people with HIV infection.

Perfluorooctane-1-sulfonic acid is a perfluoroalkanesulfonic acid that is octane-1-sulfonic acid in which all seventeen of the hydrogens that are attached to carbons hvae been replaced by fluorines. It has a role as an antilipemic drug and a persistent organic pollutant. It is functionally related to an octane-1-sulfonic acid. Perfluorooctane sulfonate (PFOS) can cause cancer according to an independent committee of scientific and health experts. It can cause developmental toxicity according to The Environmental Protection Agency (EPA). Perfluorooctanesulfonic acid or perfluorooctane sulfonate (PFOS), is a man-made fluorosurfactant and global pollutant. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009. PFOS can form from the degradation of precursors in addition to industrial production. The PFOS levels that have been detected in wildlife are considered high enough to affect health parameters, and recently higher serum levels of PFOS were found to be associated with increased risk of chronic kidney disease in the general US population, consistent with earlier animal studies. This association was independent of confounders such as age, sex, race/ethnicity, body mass index, diabetes, hypertension, and serum cholesterol level.

Vaccenic acid
Vaccenic acid is a naturally occurring trans fatty acid. It is the predominant kind of trans-fatty acid found in human milk, in the fat of ruminants, and in dairy products such as milk, butter, and yogurt. Trans fat in human milk may depend on trans fat content in food. Its IUPAC name is (11E)-11-octadecenoic acid, and its lipid shorthand name is 18:1 trans-11. The name was derived from the Latin vacca (cow). Vaccenic acid belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Vaccenic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Occurs in small proportions in ruminant fats (e.g., butter) via biohydrogenation of dietary polyene acids. Vaccenic acid is found in many foods, some of which are almond, romaine lettuce, butter, and pak choy. trans-Vaccenic acid is a precursor for the synthesis of saturated fatty acid in the rumen and of conjugated linoleic acid (CLA) at the tissue level. trans-Vaccenic acid is a precursor for the synthesis of saturated fatty acid in the rumen and of conjugated linoleic acid (CLA) at the tissue level.

Procarbazine
Procarbazine is only found in individuals that have used or taken this drug. It is an antineoplastic agent used primarily in combination with mechlorethamine, vincristine, and prednisone (the MOPP protocol) in the treatment of Hodgkins disease. [PubChem]The precise mode of cytotoxic action of procarbazine has not been clearly defined. There is evidence that the drug may act by inhibition of protein, RNA and DNA synthesis. Studies have suggested that procarbazine may inhibit transmethylation of methyl groups of methionine into t-RNA. The absence of functional t-RNA could cause the cessation of protein synthesis and consequently DNA and RNA synthesis. In addition, procarbazine may directly damage DNA. Hydrogen peroxide, formed during the auto-oxidation of the drug, may attack protein sulfhydryl groups contained in residual protein which is tightly bound to DNA.

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

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

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

Behenic acid
Behenic acid, also known as docosanoate or 1-docosanoic acid, is a member of the class of compounds known as very long-chain fatty acids. Very long-chain fatty acids are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. Thus, behenic acid is considered to be a fatty acid lipid molecule. Behenic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Behenic acid can be found in a number of food items such as rice, opium poppy, pepper (c. frutescens), and gram bean, which makes behenic acid a potential biomarker for the consumption of these food products. Behenic acid can be found primarily in blood, feces, and urine. Behenic acid (also docosanoic acid) is a carboxylic acid, the saturated fatty acid with formula C21H43COOH.

all-trans-Phytofluene
all-trans-Phytofluene is a carotenoid found in human fluids. Carotenoids are isoprenoid molecules that are widespread in nature and are typically seen as pigments in fruits, flowers, birds, and crustacea. Animals are unable to synthesize carotenoids de novo, and rely upon the diet as a source of these compounds. Over recent years there has been considerable interest in dietary carotenoids with respect to their potential in alleviating age-related diseases in humans. This attention has been mirrored by significant advances in cloning most of the carotenoid genes and in the genetic manipulation of crop plants with the intention of increasing levels in the diet. Studies have shown an inverse relationship between the consumption of certain fruits and vegetables and the risk of epithelial cancer. Since carotenoids are among the micronutrients found in cancer preventive foods, detailed qualitative and quantitative determination of these compounds, particularly in fruits and vegetables and in human plasma, have recently become increasingly important.

Camphene
Camphene, also known as 2,2-dimethyl-3-methylenebicyclo[2.2.1]heptane or 2,2-dimethyl-3-methylenenorbornane, is a member of the class of compounds known as bicyclic monoterpenoids. Bicyclic monoterpenoids are monoterpenoids containing exactly 2 rings, which are fused to each other. Monoterpenoids are terpenes that contain 10 carbon atoms and are comprised of two isoprene units. The biosynthesis of monoterpenes is known to occur mainly through the methyl-erythritol-phosphate (MEP) pathway in plastids (PMID:7640522 ). Geranyl diphosphate (GPP) is a key intermediate in the biosynthesis of cyclic monoterpenes. GPP undergoes several cyclization reactions to yield a diverse number of cyclic arrangements. Camphene is nearly insoluble in water but very soluble in common organic solvents. It volatilizes readily at room temperature and has a pungent smell. It exists as a flammable, white solid that has a minty, citrus, eucalyptus odor. It is produced industrially by catalytic isomerization of the more common alpha-pinene. Camphene is used in the preparation of fragrances and in food additives for flavouring. In the mid-19th century it was used as a fuel for lamps, but this was limited by its explosiveness. Camphene exists in all eukaryotes, ranging from yeast to plants to humans.

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

Stearoyl-CoA
Stearoyl-CoA is a long-chain acyl CoA ester that acts as an intermediate metabolite in the biosynthesis of monounsaturated fatty acids; a critical committed step in the reaction is the introduction of the cis-configuration double bond into acyl-CoAs (between carbons 9 and 10). This oxidative reaction is catalyzed by the iron-containing, microsomal enzyme, stearoyl-CoA desaturase (SCD, EC 1.14.19.1). NADH supplies the reducing equivalents for the reaction, the flavoprotein is cytochrome b5-reductase and the electron carrier is the heme protein cytochrome b5. Stearoyl-CoA is converted into oleoyl-CoA and then used as a major substrate for the synthesis of various kinds of lipids including phospholipids, triglycerides, cholesteryl esters and wax esters. Oleic acid is the preferred substrate for acyl-CoA cholesterol acyltransferase (ACAT, EC 2.3.1.26) and diacylglycerol acyltransferase (DGAT, EC 2.3.1.20), the enzymes responsible for cholesteryl esters and triglycerides synthesis, respectively. In addition oleate is the major monounsaturated fatty acid in human adipose tissue and in the phospholipid of the red-blood-cell membrane. In the biosynthesis of sphinganine, stearoyl-CoA proceeds through the acyl-CoA + serine -> 3-keto-sphinganine -> sphinganine pathway, with the key enzyme being acyl-CoA serine acyltransferase (EC 2.3.1.50) to yield C20-(3-ketosphinganine) long-chain base. There is growing recognition that acyl-CoA esters could act as signaling molecules in cellular metabolism. (PMID: 12538075, 10998569, Prostaglandins Leukot Essent Fatty Acids. 2003 Feb;68(2):113-21.)

CDP-ethanolamine
CDP-ethanolamine, also known as cytidine 5’-diphosphoethanolamine, belongs to the class of organic compounds known as CDP-ethanolamines. These are phosphoethanolamines that consist of an ethanolamine having a cytidine 5-diphosphate moiety attached to the oxygen. CDP-ethanolamine is a very strong basic compound (based on its pKa). In humans, CDP-ethanolamine is involved in phosphatidylethanolamine biosynthesis. Outside of the human body, CDP-ethanolamine has been detected, but not quantified in, several different foods, such as Chinese water chestnuts, buffalo currants, red huckleberries, eggplants, and brazil nuts. This could make CDP-ethanolamine a potential biomarker for the consumption of these foods. Cytidine is a molecule (known as a nucleoside) that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) via a beta-N1-glycosidic bond. [HMDB]. CDP-Ethanolamine is found in many foods, some of which are allspice, hedge mustard, wasabi, and green vegetables.
Dopaquinone
Dopaquinone, also known as o-dopaquinone or L-dopaquinone, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha-amino acids which have the L-configuration of the alpha-carbon atom. Dopaquinone is slightly soluble (in water) and a moderately acidic compound (based on its pKa). L-Dopaquinone is a metabolite of L-DOPA and a precursor of melanin. Melanin is synthesized from tyrosine by hydroxylation to dihydroxyphenylalanine (DOPA) and subsequent oxidation to dopaquinone. Both reactions are catalyzed by the enzyme tyrosinase, which is the rate-limiting step. Dopaquinone has an ortho-quinone ring, which is known to be neurotoxic and highly reactive with many other compounds (PMID: 413870). Dopaquinone typically combines with cysteine to form pheomelanin (a pigment-polymer). Alternatively, dopaquinone can be converted to leucodopachrome and eventually to eumelanin (also a pigment-polymer). Dopaquinone can be found in skin and feces. Within the cell, dopaquinone is primarily located in the cytoplasm. Dopaquinone is involved in several metabolic disorders, some of which include transient tyrosinemia, hawkinsinuria, tyrosinemia type I, and alkaptonuria. Chronically high levels of dopaquinone are associated with Parkinsons disease (PD). Many Parkinsons patients are treated with L-DOPA. However, long-term treatment with L-DOPA may actually worsen symptoms or 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). Dopaquinone is a substrate of enzyme monophenol monooxygenase [EC 1.14.18.1] in tyrosine metabolism pathway (KEGG). [HMDB]

L-glutamic-gamma-semialdehyde, also known as 5-oxo-L-norvaline or glutamic acid gamma-semialdehyde, (L)-isomer, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. L-glutamic-gamma-semialdehyde is soluble (in water) and a moderately acidic compound (based on its pKa). L-glutamic-gamma-semialdehyde can be found in a number of food items such as rubus (blackberry, raspberry), jackfruit, loganberry, and plains prickly pear, which makes L-glutamic-gamma-semialdehyde a potential biomarker for the consumption of these food products. L-glutamic-gamma-semialdehyde exists in all living species, ranging from bacteria to humans. In humans, L-glutamic-gamma-semialdehyde is involved in the arginine and proline metabolism. L-glutamic-gamma-semialdehyde is also involved in several metabolic disorders, some of which include hyperornithinemia-hyperammonemia-homocitrullinuria [hhh-syndrome], prolidase deficiency (PD), arginine: glycine amidinotransferase deficiency (AGAT deficiency), and ornithine aminotransferase deficiency (OAT deficiency). Glutamic gamma-semialdehyde is the metabolic precursor for proline biosynthesis. The conversion from L-Glutamate, an ATP- and NADPH-dependent reaction, is catalyzed by the enzyme Delta-1-pyrroline-5-carboxylate synthetase (P5CS) (OMIM 138250). L-Glutamic-gamma-semialdehyde can also be converted to or be formed from the amino acids L-ornithine (EC 2.6.1.13) and L-proline (EC 1.5.99.8 and EC 1.5.1.2). It is also one of the few metabolites that can be a precursor to other metabolites of both the urea cycle and the citric acid cycle (BioCyc).
Acrylamide
Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH2=CHC(O)NH2. It is a white odorless solid, soluble in water and several organic solvents. It is produced industrially as a precursor to polyacrylamides, which find many uses as water-soluble thickeners and flocculation agents. It is highly toxic, likely to be carcinogenic,and partly for that reason it is mainly handled as an aqueous solution. It is a chemical used in many industries around the world and more recently was found to form naturally in foods cooked at high temperatures. Acrylamide is a neurotoxicant, reproductive toxicant, and carcinogen in animal species. Only the neurotoxic effects have been observed in humans and only at high levels of exposure in occupational settings. The mechanism underlying neurotoxic effects of ACR may be basic to the other toxic effects seen in animals. This mechanism involves interference with the kinesin-related motor proteins in nerve cells or with fusion proteins in the formation of vesicles at the nerve terminus and eventual cell death. Neurotoxicity and resulting behavioral changes can affect reproductive performance of ACR-exposed laboratory animals with resulting decreased reproductive performance. Further, the kinesin motor proteins are important in sperm motility, which could alter reproduction parameters. Effects on kinesin proteins could also explain some of the genotoxic effects on ACR. These proteins form the spindle fibers in the nucleus that function in the separation of chromosomes during cell division. This could explain the clastogenic effects of the chemical noted in a number of tests for genotoxicity and assays for germ cell damage. Other mechanisms underlying ACR-induced carcinogenesis or nerve toxicity are likely related to an affinity for sulfhydryl groups on proteins. Binding of the sulfhydryl groups could inactive proteins/enzymes involved in DNA repair and other critical cell functions. Direct interaction with DNA may or may not be a major mechanism for cancer induction in animals. The DNA adducts that form do not correlate with tumor sites and ACR is mostly negative in gene mutation assays except at high doses that may not be achievable in the diet. All epidemiologic studies fail to show any increased risk of cancer from either high-level occupational exposure or the low levels found in the diet. In fact, two of the epidemiologic studies show a decrease in cancer of the large bowel. A number of risk assessment studies were performed to estimate increased cancer risk. The results of these studies are highly variable depending on the model. There is universal consensus among international food safety groups in all countries that examined the issue of ACR in the diet that not enough information is available at this time to make informed decisions on which to base any regulatory action. Too little is known about levels of this chemical in different foods and the potential risk from dietary exposure. Avoidance of foods containing ACR would result in worse health issues from an unbalanced diet or pathogens from under cooked foods. There is some consensus that low levels of ACR in the diet are not a concern for neurotoxicity or reproductive toxicity in humans, although further research is need to study the long-term, low-level cumulative effects on the nervous system. Any relationship to cancer risk from dietary exposure is hypothetical at this point and awaits more definitive studies. (PMID:17492525). Polyacrylamides are used as flocculants as a filtration aid in the treatment of waste water and expressed sugar juices and as clarifying agents in a variety of food products. Asparagine-derived Maillard production found in trace amounts in a variety of cooked and processed foods. Subject of a food scare in 2001-2 but concern may have been overstated.

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).

Hexanal
Hexanal is an alkyl aldehyde found in human biofluids. Human milk samples collected from women contains hexanal. Among mediators of oxidative stress, highly reactive secondary aldehydic lipid peroxidation products can initiate the processes of spontaneous mutagenesis and carcinogenesis and can also act as a growth-regulating factors and signaling molecules. In specimens obtained from adult patients with brain astrocytomas, lower levels of n-hexanal are associated with poorer patient prognosis. Hexanal has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID:22626821). Hexanal is a volatile compound that has been associated with the development of undesirable flavours. The content of hexanal, which is a major breakdown product of linoleic acid (LA, n - 6 PUFA) oxidation, has been used to follow the course of lipid oxidation and off-flavour development in foods, and have been proposed as one potential marker of milk quality. A "cardboard-like" off-flavour is frequently associated with dehydrated milk products. This effect is highly correlated with the headspace concentration of hexanal. (Food Chemistry. Volume 107, Issue 1, 1 March 2008, Pages 558-569, PMID:17934948, 17487452). Constituent of many foodstuffs. A production of aerobic enzymatic transformations of plant constits.

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

3,4-Dihydroxyphenylacetaldehyde
3,4-Dihydroxyphenylacetaldehyde (DOPAL) is a metabolite of the monoamine oxidase-catalyzed oxidative deamination of dopamine. Aldehydes are highly reactive molecules formed during the biotransformation of numerous endogenous and exogenous compounds, including biogenic amines. DOPAL generates a free radical and activates mitochondrial permeability transition, a mechanism implicated in neuron death. There is an increasing body of evidence suggesting that these compounds are neurotoxic, and it has been recently hypothesized that neurodegenerative disorders may be associated with increased levels of this biogenic aldehyde. It is possible to speculate that reduced detoxification of 3,4- dihydroxymandelaldehyde from impaired or deficient aldehyde dehydrogenase function may be a contributing factor in the suggested neurotoxicity of these compounds. Aldehyde dehydrogenases are a group of NAD(P)+ -dependent enzymes that catalyze the oxidation of aldehydes, such as those derived from catecholamines, to their corresponding carboxylic acids. To date, 19 aldehyde dehydrogenase genes have been identified in the human genome. Mutations in these genes and subsequent inborn errors in aldehyde metabolism are the molecular basis of several diseases.

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

2-Hydroxyestrone
2-Hydroxyestrone (2-OHE1), also known as estra-1,3,5(10)-trien-2,3-diol-17-one, is an endogenous, naturally occurring catechol estrogen and a major metabolite of estrone and estradiol. 2-Hydroxyestrone belongs to the class of organic compounds known as estrogens and derivatives. These are steroids with a structure containing a 3-hydroxylated estrane. Thus, 2-Hydroxyestrone is considered to be a steroid molecule. It is formed irreversibly from estrone in the liver and to a lesser extent in other tissues via 2-hydroxylation mediated by cytochrome P450 enzymes, mainly the CYP3A and CYP1A subfamilies. 2-OHE1 is the most abundant catechol estrogen in the body. 2-Hydroxyestrone is found in all vertebrates. Vertebrates, especially mammals, metabolizes estrogen into two major pathways and one minor. The two major pathways lead to 2-hydroxyestrone and 16a-hydroxyestrone (2-OHE1 and 16a OHE1, respectively). The minor pathway leads to 4-hydroxyestrone (4-OHE1). 2a-hydroxyestrone is considered to be the good steroid metabolite (PMID: 8943806) as 2-hydroxyestrone does not stimulate cell growth and it blocks the action of stronger estrogens that may be carcinogenic. 2-hydroxyestrone is not significantly uterotrophic, whereas other hydroxylated estrogen metabolites including 2-hydroxyestradiol, 16a-hydroxyestrone, estriol, 4-hydroxyestradiol, and 4-hydroxyestrone all are. A low urinary ratio of 2-hydroxyestrone to 16-alpha-hydroxyestrone is a strong predictor of breast cancer risk among women (PMID: 19502596). Estrone (also oestrone) is an estrogenic hormone secreted by the ovary. Its molecular formula is C18H22O2. estrone has a melting point of 254.5 degrees Celsius. estrone is one of the three estrogens, which also include estriol and estradiol. estrone is the least prevalent of the three hormones, estradiol being prevalent almost always in a female body, estriol being prevalent primarily during pregnancy. estrone sulfate is relevant to health and disease due to its conversion to estrone sulfate, a long-lived derivative of estrone. estrone sulfate acts as a pool of estrone which can be converted as needed to the more active estradiol.

p-Xylene
P-xylene, also known as para-xylene or 1,4-dimethylbenzene, is a member of the class of compounds known as P-xylenes. P-xylenes are aromatic compounds that contain a p-xylene moiety, which is a monocyclic benzene carrying exactly two methyl groups at the 1- and 4-positions. P-xylene can be found in a number of food items such as black walnut, yellow bell pepper, green bell pepper, and parsley, which makes P-xylene a potential biomarker for the consumption of these food products. P-xylene can be found primarily in feces and saliva. P-xylene is formally rated as an unfounded non-carcinogenic (IARC 3) potentially toxic compound. p-Xylene (para-xylene) is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes. The p- stands for para-, indicating that the two methyl groups in p-xylene occupy the diametrically opposite substituent positions 1 and 4. It is in the positions of the two methyl groups, their arene substitution pattern, that it differs from the other isomers, o-xylene and m-xylene. All have the same chemical formula C6H4(CH3)2. All xylene isomers are colorless and highly flammable. The odor threshold of p-xylene is 0.62 parts per million (ppm) . If the compound has been ingested, rapid gastric lavage should be performed using 5\\% sodium bicarbonate. For skin contact, the skin should be washed with soap and water. If the compound has entered the eyes, they should be washed with large quantities of isotonic saline or water. In serious cases, atropine and/or pralidoxime should be administered. Anti-cholinergic drugs work to counteract the effects of excess acetylcholine and reactivate AChE. Atropine can be used as an antidote in conjunction with pralidoxime or other pyridinium oximes (such as trimedoxime or obidoxime), though the use of -oximes has been found to be of no benefit, or possibly harmful, in at least two meta-analyses. Atropine is a muscarinic antagonist, and thus blocks the action of acetylcholine peripherally (T3DB). p-Xylene is an aromatic hydrocarbon based on benzene with two methyl substituents with the chemical formula C8H10 or C6H4(CH3)2. The “p” stands for para, identifying the location of the methyl groups as across from one another. (Wikipedia)

Mycophenolate mofetil
Mycophenolate mofetil is only found in individuals that have used or taken this drug. It is the 2-morpholinoethyl ester of mycophenolic acid (MPA), an immunosuppressive agent, inosine monophosphate dehydrogenase (IMPDH) inhibitor.Mycophenolate mofetil is hydrolyzed to form mycophenolic acid (MPA), which is the active metabolite. MPA is a potent, selective, uncompetitive, and reversible inhibitor of inosine monophosphate dehydrogenase (IMPDH), and therefore inhibits the de novo pathway of guanosine nucleotide synthesis without incorporation into DNA. Because T- and B-lymphocytes are critically dependent for their proliferation on de novo synthesis of purines, whereas other cell types can utilize salvage pathways, MPA has potent cytostatic effects on lymphocytes. MPA inhibits proliferative responses of T- and B-lymphocytes to both mitogenic and allospecific stimulation. Addition of guanosine or deoxyguanosine reverses the cytostatic effects of MPA on lymphocytes. MPA also suppresses antibody formation by B-lymphocytes. MPA prevents the glycosylation of lymphocyte and monocyte glycoproteins that are involved in intercellular adhesion to endothelial cells and may inhibit recruitment of leukocytes into sites of inflammation and graft rejection. Mycophenolate mofetil did not inhibit early events in the activation of human peripheral blood mononuclear cells, such as the production of interleukin-1 (IL-1) and interleukin-2 (IL-2), but did block the coupling of these events to DNA synthesis and proliferation.

Metyrosine
Metyrosine is only found in individuals that have used or taken this drug. It is an inhibitor of the enzyme tyrosine 3-monooxygenase, and consequently of the synthesis of catecholamines. It is used to control the symptoms of excessive sympathetic stimulation in patients with pheochromocytoma. (Martindale, The Extra Pharmacopoeia, 30th ed)Metyrosine inhibits tyrosine hydroxylase, which catalyzes the first transformation in catecholamine biosynthesis, i.e., the conversion of tyrosine to dihydroxyphenylalanine (DOPA). Because the first step is also the rate-limiting step, blockade of tyrosine hydroxylase activity results in decreased endogenous levels of catecholamines and their synthesis. This consequently, depletes the levels of the catecholamines dopamine, adrenaline and noradrenaline in the body,usually measured as decreased urinary excretion of catecholamines and their metabolites. One main end result of the catecholamine depletion is a decrease in blood presure.

CE(16:0)
CE(16:0), also known as cholesteryl palmitic acid, is a cholesteryl ester. A cholesteryl ester is an ester of cholesterol. Fatty acid esters of cholesterol constitute about two-thirds of the cholesterol in the plasma. Cholesterol is a sterol (a combination of steroid and alcohol) and a lipid found in the cell membranes of all body tissues and transported in the blood plasma of all animals. The accumulation of cholesterol esters in the arterial intima (the innermost layer of an artery, in direct contact with the flowing blood) is a characteristic feature of atherosclerosis. Atherosclerosis is a disease affecting arterial blood vessels. It is a chronic inflammatory response in the walls of arteries, in large part to the deposition of lipoproteins (plasma proteins that carry cholesterol and triglycerides). CE(16:0) may also accumulate in hereditary hypercholesterolemia, an inborn error of metabolism. Cholesteryl palmitate is one of the four important lipids found in the tear film. Amniotic fluid cholesteryl palmitate, as measured by thin-layer chromatography, appears to be a very sensitive and specific predictor for the risk of respiratory distress syndrome (RDS) in newborns of normal pregnancies (PMID:3405552, 16922549).

24-Hydroxycholesterol
24-Hydroxycholesterol (24OHC) is almost exclusively formed in the brain. The enzymatic conversion of CNS cholesterol to 24OHC, which readily crosses the blood-brain barrier, is the major pathway for brain cholesterol elimination and brain cholesterol homeostasis maintenance. The enzyme mediating this conversion has been characterized at the molecular level as cholesterol 24-hydroxylase (EC 1.14.13.98, CYP46) and is mainly located in neurons. Like other oxysterols, 24OHC is efficiently converted into normal bile acids or excreted in bile in its sulfated and glucuronidated form. Levels of 24OHC in the circulation decrease with age in infants and children. In adults, however, the levels appear to be stable. There is accumulating evidence pointing toward a potentially important link between cholesterol, beta-amyloid, and Alzheimers disease. Patients with active demyelinating diseases had increased levels of 24OHC in cerebrospinal fluid (CSF). Patients with Alzheimers disease have slightly increased levels of 24OHC in CSF. Patients with multiple sclerosis have a tendency to have higher levels of 24OHC during active periods. (PMID: 15061359, 14574622). 24-Hydroxycholesterol has been found to accumulate in hereditary hypercholesterolemia, an inborn error of metabolism. 24-Hydroxycholesterol (24OHC) is almost exclusively formed in the brain.

(PMID: 15061359, 14574622) [HMDB] 24(S)-Hydroxycholesterol (24S-OHC), the major brain cholesterol metabolite, plays an important role to maintain homeostasis of cholesterol in the brain. 24(S)-Hydroxycholesterol (24S-OHC) is one of the most efficient endogenous LXR agonist known and is present in the brain and in the circulation at relatively high levels. 24(S)-Hydroxycholesterol (24S-OHC) is a very potent, direct, and selective positive allosteric modulator of NMDARs with a mechanism that does not overlapthat of other allosteric modulators[1][2][3]. 24(S)-Hydroxycholesterol (24S-OHC), the major brain cholesterol metabolite, plays an important role to maintain homeostasis of cholesterol in the brain. 24(S)-Hydroxycholesterol (24S-OHC) is one of the most efficient endogenous LXR agonist known and is present in the brain and in the circulation at relatively high levels. 24(S)-Hydroxycholesterol (24S-OHC) is a very potent, direct, and selective positive allosteric modulator of NMDARs with a mechanism that does not overlapthat of other allosteric modulators[1][2][3].
Levuglandin E2
Levuglandin E2 is a levuglandin generated in the cyclooxygenase (COX) pathway. Levuglandins (LGs) and their stereo and structural isomers are extraordinarily reactive γ-ketoaldehydes that are generated by rearrangements of prostanoid endoperoxide intermediates of polyene cyclooxygenation. Their rapid adduction with biological nucleophiles results, inter alia, in pathological modifications of proteins and DNA. It also complicates their detection. Cyclooxygenase-promoted lipid oxidation is a pivotal step in the biosynthesis of an array of physiologically active metabolites. COX fosters a highly regio and stereoselective cyclooxygenation of arachidonic acid (AA) to deliver a single, enantiomerically pure endoperoxide, PGH2, that is a branch point in the biosynthesis of numerous hormone-like mediators of cellular activities. Spontaneous rearrangements of PGH2 were known to generate prostaglandins (PG) PGD2 and PGE2. (PMID: 15752459) [HMDB] Levuglandin E2 is a levuglandin generated in the cyclooxygenase (COX) pathway.

MG(20:4(5Z,8Z,11Z,14Z)/0:0/0:0)
MG(20:4(5Z,8Z,11Z,14Z)/0:0/0:0) is a monoacylglyceride. A monoglyceride, more correctly known as a monoacylglycerol, is a glyceride consisting of one fatty acid chain covalently bonded to a glycerol molecule through an ester linkage. Monoacylglycerol can be broadly divided into two groups; 1-monoacylglycerols (or 3-monoacylglycerols) and 2-monoacylglycerols, depending on the position of the ester bond on the glycerol moiety. Normally the 1-/3-isomers are not distinguished from each other and are termed alpha-monoacylglycerols, while the 2-isomers are beta-monoacylglycerols. Monoacylglycerols are formed biochemically via release of a fatty acid from diacylglycerol by diacylglycerol lipase or hormone sensitive lipase. Monoacylglycerols are broken down by monoacylglycerol lipase. They tend to be minor components only of most plant and animal tissues, and indeed would not be expected to accumulate because their strong detergent properties would have a disruptive effect on membranes. 2-Monoacylglycerols are a major end product of the intestinal digestion of dietary fats in animals via the enzyme pancreatic lipase. They are taken up directly by the intestinal cells and converted to triacylglycerols via the monoacylglycerol pathway before being transported in lymph to the liver. Mono- and Diglycerides are commonly added to commercial food products in small quantities. They act as emulsifiers, helping to mix ingredients such as oil and water that would not otherwise blend well.

Cholesterol sulfate
Cholesterol sulfate, or cholest-5-en-3beta-ol sulfate, is an endogenous steroid and the C3beta sulfate ester of cholesterol. It is formed from cholesterol by steroid sulfotransferases (SSTs) such as SULT2B1b (also known as cholesterol sulfotransferase) and is converted back into cholesterol by steroid sulfatase (STS). Accumulation of cholesterol sulfate in the skin is implicated in the pathophysiology of X-linked ichthyosis, a congenital disorder in which STS is non-functional and the body cannot convert cholesterol sulfate back into cholesterol. Cholesterol sulfate is quantitatively the most important known sterol sulfate in human plasma, where it is present in a concentration that overlaps that of the other abundant circulating steroid sulfate, dehydroepiandrosterone (DHEA) sulfate (PMID 12730293). Cholesterol sulfate has a stabilizing function on the membrane, supports platelet adhesion and is involved in signal transduction (PMID 12730293). It plays a role in protecting erythrocytes from osmotic lysis and regulating sperm capacitation. Cholesterol sulfate can regulate the activity of serine proteases, e.g., those involved in blood clotting, fibrinolysis, and epidermal cell adhesion (PMID 12730293). As a result of its ability to regulate the activity of selective protein kinase C isoforms and modulate the specificity of phosphatidylinositol 3-kinase, cholesterol sulfate is involved in signal transduction (PMID 12730293). Cholesterol sulfate functions in keratinocyte differentiation, inducing genes that encode for key components involved in development of the barrier (PMID 12730293). Cholesterol sulfate is a sterol sulfate in human plasma. It is a component of cell membrane and has a regulatory function. It has a stabilizing function on the membrane, supports platelet adhesion and involves in signal transduction.

Biopterin
Biopterin concentrations in cerebrospinal fluid from patients with Parkinsons disease, in which the nigrostriatal dopamine neurons degenerate, are lower than those from age-matched older controls. In hereditary progressive dystonia/DOPA-responsive dystonia, which is a dopamine deficiency caused by mutations in GTP cyclohydrolase I without neuronal cell death (Segawas disease), biopterin in cerebrospinal fluid decrease in parallel owing to the decreased activity in GTP cyclohydrolase I (EC 3.5.4.16, is an enzyme that is part of the folate and biopterin biosynthesis pathways. It is responsible for the hydrolysis of guanosine triphosphate (GTP) to form 7,8-dihydroneopterin 3-triphosphate. (Pteridines (1999), 10(1), 5-13.) Lowered levels of urinary biopterin concomitant with elevated serum phenylalanine concentration occur in a variant type of hyperphenylalaninemia caused by a deficiency of tetrahydrobiopterin (BH4), the obligatory cofactor for phenylalanine hydroxylase. The most frequent form of this cofactor deficiency is due to lack of 6-pyruvoyl-tetrahydropterin synthase (PTPS) activity, the second enzyme in the biosynthetic pathway for BH4. (PMID 8178819) The hepatic phenylalanine hydroxylating system consists of 3 essential components, phenylalanine hydroxylase, dihydropteridine reductase, and the nonprotein coenzyme, tetrahydrobiopterin. The reductase and the pterin coenzyme are also essential components of the tyrosine and tryptophan hydroxylating systems. There are 3 distinct forms of phenylketonuria or hyperphenylalaninemia, each caused by lack of 1 of these essential components. The variant forms of the disease that are caused by the lack of dihydropteridine reductase or tetrahydrobiopterin are characterized by severe neurol. deterioration, impaired functioning of tyrosine and tryptophan hydroxylases, and the resultant deficiency of tyrosine- and tryptophan-derived monoamine neurotransmitters in brain. (PMID 3930837) [HMDB] Biopterin, also known as tetrahydrobiopterin or BH4, belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative. Biopterin or tetrahydrobiopterin is also classified as a pterin derivative that consists of pterin group bearing an amino, an oxo and a 1,2-dihydroxypropyl substituent at positions 2, 4 and 6, respectively. Biopterin compounds found within the animals include BH4 (tetrahydrobiopterin), the free radical BH3, and BH2 (also a free radical, called Dihydrobiopterin). BH2 is produced in the synthesis of L-DOPA, dopamine, norepinephrine and epinephrine. It is restored to the required cofactor tetrahydrobiopterin by the enzyme dihydrobiopterin reductase. Tetrahydrobiopterin (BH4) is a cofactor of the three aromatic amino acid hydroxylase enzymes, used in the degradation of amino acid phenylalanine and in the biosynthesis of the neurotransmitters serotonin (5-hydroxytryptamine, 5-HT), melatonin, dopamine, norepinephrine (noradrenaline), epinephrine (adrenaline). It is also a cofactor for the production of nitric oxide (NO) by the nitric oxide syntheses. Tetrahydrobiopterin is biosynthesized from guanosine triphosphate (GTP) by three chemical reactions mediated by the enzymes GTP cyclohydrolase I (GTPCH), 6-pyruvoyltetrahydropterin synthase (PTPS), and sepiapterin reductase (SR). Biopterin synthesis disorders are a cause of hyperphenylalaninemia. There are 3 distinct forms of phenylketonuria or hyperphenylalaninemia, each caused by lack of aromatic amino acid hydroxylase enzymes. The variant forms of hyperphenylalaninemia that are caused by the lack of dihydropteridine reductase or tetrahydrobiopterin are characterized by severe neurological deterioration, impaired functioning of tyrosine and tryptophan hydroxylases, and the resultant deficiency of tyrosine- and tryptophan-derived monoamine neurotransmitters in brain. (PMID 3930837). 6-Biopterin (L-Biopterin), a pterin derivative, is a NO synthase cofactor.
7,8-Dihydroneopterin
7,8-Dihydroneopterin, also known as dihydroneopterin, belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative. They are synthesized in several parts of the body, including the pineal gland. 7,8-Dihydroneopterin is a strong basic compound (based on its pKa). Within humans, 7,8-dihydroneopterin participates in a number of enzymatic reactions. In particular, 7,8-dihydroneopterin can be biosynthesized from sepiapterin; which is catalyzed by the enzyme sepiapterin reductase or carbonyl reductase [NADPH] 1. In humans, 7,8-dihydroneopterin is involved in the metabolic disorder called hyperphenylalaninemia due to 6-pyruvoyltetrahydropterin synthase (PTPS) deficiency. 7,8-Dihydroneopterin is produced by human monocyte-derived macrophages upon stimulation with interferon-gamma. Increased amounts of 7,8-dihydroneopterin in human body fluids are found in many disorders, including viral infections and autoimmune diseases (PMID: 12804528). 7,8-dihydroneopterin, also known as npr, belongs to biopterins and derivatives class of compounds. Those are coenzymes containing a 2-amino-pteridine-4-one derivative. They are mainly synthesized in several parts of the body, including the pineal gland. 7,8-dihydroneopterin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 7,8-dihydroneopterin can be found in a number of food items such as prickly pear, star anise, cocoa bean, and black salsify, which makes 7,8-dihydroneopterin a potential biomarker for the consumption of these food products. 7,8-dihydroneopterin exists in all living organisms, ranging from bacteria to humans. In humans, 7,8-dihydroneopterin is involved in the pterine biosynthesis. 7,8-dihydroneopterin is also involved in several metabolic disorders, some of which include hyperphenylalaninemia due to dhpr-deficiency, sepiapterin reductase deficiency, dopa-responsive dystonia, and hyperphenylalaniemia due to guanosine triphosphate cyclohydrolase deficiency. 7,8-Dihydroneopterin, an inflammation marker, induces cellular apoptosis in astrocytes and neurons via enhancement of nitric oxide synthase (iNOS) expression. 7,8-Dihydroneopterin can be used in the research of neurodegenerative diseases[1].
Hippuric acid
Hippuric acid (Gr. hippos, horse, ouron, urine) is a carboxylic acid found in the urine of horses and other herbivores. Hippuric acid crystallizes in rhombic prisms which are readily soluble in hot water, melt at 187 °C and decompose at about 240 °C. High concentrations of hippuric acid can also indicate a toluene intoxication. When many aromatic compounds such as benzoic acid and toluene are taken internally, they are converted to hippuric acid by reaction with the amino acid, glycine.; Hippuric acid is an acyl glycine formed by the conjugation of benzoic aicd with glycine. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction: acyl-CoA + glycine < -- > CoA + N-acylglycine. Hippuric acid is a normal component of urine and is typically increased with increased consumption of phenolic compounds (tea, wine, fruit juices). These phenols are converted to benzoic acid which is then converted to hippuric acid and excreted in the urine. Hippuric acid is the most frequently used biomarker in the biological monitoring of occupational exposure to toluene. This product of solvent biotransformation may be also found in the urine of individuals who have not been exposed to the solvent. A smaller fraction of the absorbed toluene is oxidized to aromatic compounds including ortho-cresol, which is not found significantly in the urine of nonexposed individuals. The concentration of hippuric acid in the urine of individuals exposed to a low toluene concentration does not differ from that of individuals not exposed to the solvent. This has led to the conclusion that hippuric acid should not be utilized in the biological monitoring of occupational exposure to low levels of toluene in the air.; Protein-bound organic acids such as hippuric acid are markedly accumulated in uremic plasma and produce defective protein binding of drugs. (PMID: 9120876, 8734460). Hippuric acid is an acyl glycine formed from the conjugation of benzoic acid with glycine.

Protein-bound organic acids such as hippuric acid are markedly accumulated in uremic plasma and produce defective protein binding of drugs (PMID: 9120876 , 8734460). Hippuric acid has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Hippuric acid is also found to be associated with phenylketonuria, propionic acidemia, and tyrosinemia I, which are inborn errors of metabolism.

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

FA(16:1)
Palmitoleic acid (FA 16:1), also known as hexadecenoic acid, is a monounsaturated omega-7 fatty acid with a 16-carbon chain and a double bond at the 9th position. In biological terms, palmitoleic acid serves several important functions: 1. **Energy Source:** Like other fatty acids, palmitoleic acid is a significant source of energy. It can be oxidized through beta-oxidation to produce ATP, the energy currency of the cell. 2. **Cell Membrane Structure:** Palmitoleic acid is a component of phospholipids, which are major constituents of cell membranes. The presence of monounsaturated fatty acids like palmitoleic acid helps maintain the fluidity and flexibility of cell membranes, which is crucial for various cellular processes. 3. **Lipid Signaling:** Palmitoleic acid and its derivatives can act as signaling molecules. For example, it is converted into the lipid mediator called palmitoleoyl-lysophosphatidylcholine (LPC), which plays a role in inflammation and blood clotting. 4. **Insulin Sensitivity:** Palmitoleic acid has been shown to improve insulin sensitivity, which is important for glucose metabolism and can help in the prevention and treatment of type 2 diabetes. 5. **Inflammation Modulation:** Some studies suggest that palmitoleic acid may have anti-inflammatory effects, which could be beneficial in reducing the risk of chronic diseases associated with inflammation. 6. **Skin Health:** Palmitoleic acid is naturally present in the skin and is considered a component of the skin's surface lipids, contributing to the skin's barrier function and helping to prevent water loss. 7. **Biosynthesis of Other Lipids:** Palmitoleic acid serves as a precursor for the synthesis of other complex lipids, including prostaglandins and other eicosanoids, which are involved in a wide range of physiological processes such as inflammation and blood pressure regulation. 8. **Cardiovascular Health:** The consumption of monounsaturated fatty acids like palmitoleic acid is often associated with a lower risk of cardiovascular diseases, although the direct role of palmitoleic acid in this context is still under investigation. It's important to note that while palmitoleic acid has these potential biological functions, the overall impact on health can depend on the balance of fatty acids in the diet and the context of the individual's overall metabolic health. Palmitoleic acid, a composition of fatty acid, is implicated in the prevention of death from cerebrovascular disorders in SHRSP rats.

Rumenic acid
Bovinic acid is a conjugated linoleic acid, present in human adipose tissue; the amount of bovinic acid in humans is significantly related to milk fat intake. Conjugated linoleic acids (CLAs) are a group of naturally occurring fatty acids present mainly in fats from ruminants. Milk contains over 20 isomers of CLA but the predominant one is cis-9,trans-11-CLA (bovinic acid). Biomedical studies with animal models have shown that this isomer has anticarcinogenic and anti-atherogenic activities. Bovinic acid is produced as an intermediate in the rumen biohydrogenation of linoleic acid but not of linolenic acid. However, it is only a transient intermediate, and the major source of milk fat CLA is from endogenous synthesis. (PMID 10393134, 15736916) [HMDB]

Zeaxanthin
Meso-zeaxanthin (3R,3´S-zeaxanthin) is a xanthophyll carotenoid, as it contains oxygen and hydrocarbons, and is one of the three stereoisomers of zeaxanthin. Of the three stereoisomers, meso-zeaxanthin is the second most abundant in nature after 3R,3´R-zeaxanthin, which is produced by plants and algae. To date, meso-zeaxanthin has been identified in specific tissues of marine organisms and in the macula lutea, also known as the "yellow spot", of the human retina . Meso-zeaxanthin is a member of the class of compounds known as xanthophylls. Xanthophylls are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone. Meso-zeaxanthin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Meso-zeaxanthin can be found in channel catfish, crustaceans, and fishes, which makes meso-zeaxanthin a potential biomarker for the consumption of these food products.

Perfluorooctanesulfonic acid
Perfluorooctanesulfonic acid or perfluorooctane sulfonate (PFOS), is a man-made fluorosurfactant and global pollutant. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009. PFOS can form from the degradation of precursors in addition to industrial production. The PFOS levels that have been detected in wildlife are considered high enough to affect health parameters, and recently higher serum levels of PFOS were found to be associated with increased risk of chronic kidney disease in the general US population, consistent with earlier animal studies. This association was independent of confounders such as age, sex, race/ethnicity, body mass index, diabetes, hypertension, and serum cholesterol level. Perfluorooctanesulfonic acid.
