Melamine
Melamine is an organic base and a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 66\\\% nitrogen by mass and, if mixed with resins, has fire retardant properties due to its release of nitrogen gas when burned or charred, and has several other industrial uses. Melamine is also a metabolite of cyromazine, a pesticide. It is formed in the body of mammals who have ingested cyromazine. It has been reported that cyromazine can also be converted to melamine in plants. Melamine is combined with formaldehyde to produce melamine resin, a very durable thermosetting plastic used in Formica, and melamine foam, a polymeric cleaning product. The end products include countertops, dry erase boards, fabrics, glues, housewares, dinnerware, cooking spoons, guitar saddles, guitar nuts, acoustic foam paneling, and flame retardants. Melamine is one of the major components in Pigment Yellow 150, a colorant in inks and plastics. Melamine is sometimes illegally added to food products in order to increase the apparent protein content. Standard tests, such as the Kjeldahl and Dumas tests, estimate protein levels by measuring the nitrogen content, so they can be misled by adding nitrogen-rich compounds such as melamine.There is an instrument (SPRINT) developed by the company CEM Corp that allows the determination of protein content directly in some applications; this cannot be fooled by adding melamine in the sample. Ultrasound-assisted extractive electrospray ionization mass spectrometry (EESI-MS) has been developed at ETH Zurich (Switzerland) by Zhu et al., (2008) for a rapid detection of melamine in untreated food samples. Ultrasounds are used to nebulize the melamine-containing liquids into a fine spray. The spray is then ionised by extractive electrospray ionisation (EESI) and analysed using tandem mass spectrometry (MS/MS). An analysis requires 30 seconds per sample. The limit of detection of melamine is a few nanograms of melamine per gram of milk. Crystallization and washing of melamine generates a considerable amount of waste water, which is a pollutant if discharged directly into the environment. The waste water may be concentrated into a solid (1.5-5\\\% of the weight) for easier disposal. The solid may contain approximately 70\\\% melamine, 23\\\% oxytriazines (ammeline, ammelide, and cyanuric acid), 0.7\\\% polycondensates (melem, melam, and melon). In the Eurotecnica process, however, there is no solid waste and the contaminants are decomposed to ammonia and carbon dioxide and sent as off gas to the upstream urea plant; accordingly, the waste water can be recycled to the melamine plant itself or used as clean cooling water make-up. Melamine also enters the fabrication of melamine poly-sulfonate used as superplasticizer for making high-resistance concrete. Sulfonated melamine formaldehyde (SMF) is a polymer used as cement admixture to reduce the water content in concrete while increasing the fluidity and the workability of the mix during its handling and pouring. It results in concrete with a lower porosity and a higher mechanical strength, exhibiting an improved resistance to aggressive environments and a longer life-time. Melamine appears as colorless to white monoclinic crystals or prisms or white powder. Sublimes when gently heated. (NTP, 1992) Melamine is a trimer of cyanamide, with a 1,3,5-triazine skeleton. It has a role as a xenobiotic metabolite. It is functionally related to a cyanamide. It is a conjugate base of a melamine(1+). Melamine is a natural product found in Euglena gracilis, Aeromonas veronii, and Apis cerana with data available. Melamine is an organic base and a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 66\\\% nitrogen by mass and, if mixed with resins, has fire retardant properties due to its release of nitrogen gas when burned or charred, and has several other industrial uses. Melamine is also a metabolite of cyromazine, a pesticide. It is formed in the body of mammals who have ingested cyromazine. It has been reported that cyromazine can also be converted to melamine in plants. Melamine is described as Harmful if swallowed, inhaled or absorbed through the skin. Chronic exposure may cause cancer or reproductive damage. Eye, skin and respiratory irritant. However, the short-term lethal dose is on a par with common table salt with an LD50 of more than 3 grams per kilogram of bodyweight.[15] U.S. Food and Drug Administration (FDA) scientists explained that when melamine and cyanuric acid are absorbed into the bloodstream, they concentrate and interact in the urine-filled renal tubules, then crystallize and form large numbers of round, yellow crystals, which in turn block and damage the renal cells that line the tubes, causing the kidneys to malfunction.

Maltoheptaose
Maltoheptaose is a polysaccharide with 7 units of glucose and can be classified as a maltodextrin. Maltodextrin is a polysaccharide that is used as a food additive. It is produced from starch by partial hydrolysis and is usually found as a creamy-white hygroscopic spray-dried powder. Maltodextrin is easily digestible, being absorbed as rapidly as glucose, and might be either moderately sweet or almost flavourless. It is commonly used for the production of natural sodas and candy such as SweeTarts. Maltodextrin consists of D-glucose units connected in chains of variable length. The glucose units are primarily linked with α(1→4) glycosidic bonds. Maltodextrin is typically composed of a mixture of chains that vary from three to nineteen glucose units long. Maltodextrins are classified by DE (dextrose equivalent) and have a DE between 3 to 20. The higher the DE value, the shorter the glucose chains, and the higher the sweetness and solubility. Above DE 20, the European Unions CN code calls it glucose syrup, at DE 10 or lower the customs CN code nomenclature classifies maltodextrins as dextrins (Wikipedia). Maltooligosaccharide mixtures are important food additives (sweeteners, gelling agents and viscosity modifiers) Celloheptaose is an oligosaccharide.
3,4-Dihydroxyphenylglycol
3,4-Dihydroxyphenylglycol, also known as DHPG or DOPEG, belongs to the class of organic compounds known as catechols. Catechols are compounds containing a 1,2-benzenediol moiety. 3,4-Dihydroxyphenylglycol is an extremely weak basic (essentially neutral) compound. 3,4-Dihydroxyphenylglycol exists in all living organisms, ranging from bacteria to plants to humans. It is a potent antioxidant (PMID: 30007612). In mammals, 3,4-Dihydroxyphenylglycol is the primary metabolite of norepinephrine and is generated through the action of the enzyme monoamine oxidase (MAO). DHPG is then further metabolized by the enzyme Catechol-O-methyltransferase (COMT) to 3-methoxy-4-hydroxyphenylglycol (MHPG). Within humans, 3,4-dihydroxyphenylglycol participates in a number of enzymatic reactions. In particular, 3,4-dihydroxyphenylglycol can be biosynthesized from 3,4-dihydroxymandelaldehyde; which is mediated by the enzyme alcohol dehydrogenase 1A. In addition, 3,4-dihydroxyphenylglycol and guaiacol can be converted into vanylglycol and pyrocatechol through its interaction with the enzyme catechol O-methyltransferase. Outside of the human body, 3,4-dihydroxyphenylglycol is found, on average, in the highest concentration in olives. High levels of DHPG (up to 368 mg/kg of dry weight) have been found in the pulp of natural black olives. This could make 3,4-dihydroxyphenylglycol a potential biomarker for the consumption of olives and olive oil. 3,4-Dihydroxyphenylglycol has been linked to Menkes disease (PMID: 19234788). DHPG level are lower in Menkes patients (3.57 ± 0.40 nM) than healthy infants 8.91 ± 0.77 nM). Menkes disease (also called “kinky hair disease”) is an X-linked recessive neurodevelopmental disorder caused by defects in a gene that encodes a copper-transporting ATPase (ATP7A). Affected infants typically appear healthy at birth and show normal neurodevelopment for 2-3 months. Subsequently there is loss of milestones (e.g., smiling, visual tracking, head control) and death in late infancy or childhood (PMID: 19234788). 3,4-Dihydroxyphenylglycol (DOPEG) is a normal norepinephrine metabolite present in CSF, plasma and urine in humans (PMID 6875564). In healthy individuals there is a tendency for free DOPEG to increase and for conjugated DOPEG to decrease with age; plasmatic DOPEG levels are significantly lower in depressed patients as compared to healthy controls (PMID 6671452). DL-1-(3,4-Dihydroxyphenyl)-1,2-ethanediol is found in olive. 4-(1,2-Dihydroxyethyl)benzene-1,2-diol, a normal norepinephrine metabolite, is found to be associated with Menkes syndrome.

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].
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).

Isoxanthopterin
Isoxanthopterin is a pteridine normally present in plasma, urine, and other bodily fluids also vary from normal concentrations in some disease states and also have diagnostic value. Pteridines urinary concentrations seem to vary independently from each other and from normal values to yield a pattern of excreted pteridines that is diagnostic for different species, tissues, and tumor types. Intravenous or intramuscular administration of isoxanthopterin inhibits the growth rates of animal tumor models. ; Pteridin derivatives are a family of organic compound with very similar chemical structures which play an important biochemistry role. Pteridines metabolism and its regulation in normal and pathological conditions have not been extensively investigated due to the difficulty of their quantification. A significant decrease of isoxanthopterin has been determined in cancer patients. (PMID 15837549, 9800651); Xanthine dehydrogenase (XDH) is the enzymes responsible for the conversion of xanthine to uric acid. It requires the presence of the molybdenum cofactor for its proper functioning.

Sepiapterin
Sepiapterin, also known as 2-amino-6-lactoyl-7,8-dihydropteridin-4(3H)-one, belongs to the class of organic compounds known as pterins and derivatives. These are polycyclic aromatic compounds containing a pterin moiety, which consist of a pteridine ring bearing a ketone and an amine group to form 2-aminopteridin-4(3H)-one. Sepiapterin is also classified as a member of the pteridine class of organic chemicals. It is a yellow fluorescing pigment. Sepiapterin is an intermediate in the salvage pathway of tetrahydrobiopterin (BH(4)). More specifically, sepiapterin can be metabolized into tetrahydrobiopterin via the BH(4) salvage pathway. Tetrahydrobiopterin is an essential cofactor in humans for breakdown of phenylalanine and a catalyst of the metabolism of phenylalanine, tyrosine, and tryptophan to the neurotransmitters dopamine and serotonin. A deficiency of tetrahydrobiopterin can cause toxic buildup of phenylalanine (phenylketonuria) as well as deficiencies of dopamine, norepinephrine, and epinephrine, leading to dystonia and other neurological illnesses. Sepiapterin accumulates in the brain of patients with sepiapterin reductase (SR) deficiency, an inborn error of metabolism. Sepiapterin reductase deficiency is a condition characterized by movement problems, most often a pattern of involuntary, sustained muscle contractions known as dystonia. Other movement problems can include muscle stiffness (spasticity), tremors, problems with coordination and balance (ataxia), and involuntary jerking movements (chorea). People with sepiapterin reductase deficiency can experience episodes called oculogyric crises. These episodes involve abnormal rotation of the eyeballs; extreme irritability and agitation; and pain, muscle spasms, and uncontrolled movements, especially of the head and neck. Movement abnormalities are often worse late in the day. Most affected individuals have delayed development of motor skills such as sitting and crawling, and they typically are not able to walk unassisted. The problems with movement tend to worsen over time. Within humans, sepiapterin participates in a number of enzymatic reactions. In particular, sepiapterin can be converted into 7,8-dihydroneopterin; which is mediated by the enzyme sepiapterin reductase. In addition, sepiapterin can be converted into 7,8-dihydroneopterin through its interaction with the enzyme carbonyl reductase [NADPH] 1. Sepiapterin is an intermediate in the salvage pathway of tetrahydrobiopterin (BH(4)). It is a yellow fluorescing pigment. Sepiapterin accumulates in the brain of patients with sepiapterin reductase (SR) deficiency. [HMDB] C307 - Biological Agent
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.
Methylmalonic acid
Methylmalonic acid is a malonic acid derivative, which is a vital intermediate in the metabolism of fat and protein. In particular, the coenzyme A-linked form of methylmalonic acid, methylmalonyl-CoA, is converted into succinyl-CoA by methylmalonyl-CoA mutase in a reaction that requires vitamin B12 as a cofactor. In this way, methylmalonic acid enters the Krebs cycle and is thus part of one of the anaplerotic reactions. Abnormalities in methylmalonic acid metabolism lead to methylmalonic aciduria. This inborn error of metabolism is attributed to a block in the enzymatic conversion of methylmalonyl CoA to succinyl CoA. Methylmalonic acid is also found to be associated with other inborn errors of metabolism, including cobalamin deficiency, cobalamin malabsorption, malonyl-CoA decarboxylase deficiency, and transcobalamin II deficiency. When present in sufficiently high levels, methylmalonic acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of methylmalonic acid are associated with at least 5 inborn errors of metabolism, including Malonyl CoA decarboxylase deficiency, Malonic Aciduria, Methylmalonate Semialdehyde Dehydrogenase Deficiency, Methylmalonic Aciduria and Methylmalonic Aciduria Due to Cobalamin-Related Disorders. Methylmalonic acid is an organic acid and abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart abnormalities, kidney abnormalities, liver damage, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. A malonic acid derivative which is a vital intermediate in the metabolism of fat and protein. Abnormalities in methylmalonic acid metabolism lead to methylmalonic aciduria. This metabolic disease is attributed to a block in the enzymatic conversion of methylmalonyl CoA to succinyl CoA.

N-Glycolylneuraminic acid
N-Glycolylneuraminic acid (Neu5Gc) is a widely expressed sialic acid found in most mammalian cells. Although humans are genetically deficient in producing Neu5Gc, small amounts are present in human cells and biofluids. Humans cannot synthesize Neu5Gc because the human gene CMAH is irreversibly mutated, though it is found in apes. This loss of the CMAH gene was estimated to have occurred two to three million years ago, just before the emergence of the genus Homo. A dietary origin of Neu5Gc was suggested by human volunteer studies. These trace amounts of Neu5Gc were determined to come from the consumption of animals in the human diet (i.e. red meats such as lamb, pork, and beef). Neu5Gc can also be found in dairy products, but to a lesser extent. Neu5Gc is not found in poultry and is found in only trace amounts in fish (Wikipedia). Isolated from beef serum KEIO_ID G062

Granisetron
Granisetron is only found in individuals that have used or taken this drug. It is a serotonin receptor (5HT-3 selective) antagonist that has been used as an antiemetic and antinauseant for cancer chemotherapy patients. [PubChem]Granisetron is a potent, selective antagonist of 5-HT3 receptors. The antiemetic activity of the drug is brought about through the inhibition of 5-HT3 receptors present both centrally (medullary chemoreceptor zone) and peripherally (GI tract). This inhibition of 5-HT3 receptors in turn inhibits the visceral afferent stimulation of the vomiting center, likely indirectly at the level of the area postrema, as well as through direct inhibition of serotonin activity within the area postrema and the chemoreceptor trigger zone.

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.

Rimantadine
Rimantadine is only found in individuals that have used or taken this drug. It is an RNA synthesis inhibitor that is used as an antiviral agent in the prophylaxis and treatment of influenza. [PubChem]The mechanism of action of rimantadine is not fully understood. Rimantadine appears to exert its inhibitory effect early in the viral replicative cycle, possibly inhibiting the uncoating of the virus. Genetic studies suggest that a virus protein specified by the virion M2 gene plays an important role in the susceptibility of influenza A virus to inhibition by rimantadine.

It belongs to the family of N-acyl-alpha amino acids and derivatives. These are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. gamma-Glutamylcysteine is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. gamma-Glutamylcysteine is a product of enzyme glutamate-cysteine ligase [EC 6.3.2.2] and a substrate of enzyme glutathione synthase [EC 6.3.2.3] in the glutamate metabolism pathway (KEGG). G-Glutamylcysteine is a product of enzyme glutamate-cysteine ligase [EC 6.3.2.2] and a substrate of enzyme glutathione synthase [EC 6.3.2.3] in glutamate metabolism pathway (KEGG). gamma-Glutamyl-cysteine is found in many foods, some of which are cardamom, hyacinth bean, oil palm, and pak choy.

3-(4-hydroxyphenyl)lactate
Hydroxyphenyllactic acid or 4-hydroxyphenyllactate (the L-form) is a tyrosine metabolite. The level of L-hydroxyphenyllactic acid is elevated in patients with a deficiency of the enzyme p-hydroxyphenylpyruvate oxidase (EC 1.14.2.2) (PMID: 4720815). L-hydroxyphenyllactate is present in relatively higher concentrations in the cerebrospinal fluid and urine of patients with phenylketonuria (PKU) and tyrosinemia (PMID: 3126358). However, the D-form of hydroxyphenyllactate is of bacterial origin and is also found in individuals with bacterial overgrowth or unusual gut microflora (PMID: 3126358). Microbial hydroxyphenyllactate is likely derived from phenolic or polyphenolic compounds in the diet. Bifidobacteria and lactobacilli produce considerable amounts of phenyllactic and p-hydroxyphenyllactic acids (PMID: 23061754). It has also been shown that hydroxyphenyllactate decreases ROS (reactive oxygen species) production in both mitochondria and neutrophils and so hydroxyphenyllactate may function as a natural anti-oxidant (PMID: 23061754). Hydroxyphenyllactic acid is a microbial metabolite found in Acinetobacter, Bacteroides, Bifidobacteria, Bifidobacterium, Clostridium, Enterococcus, Escherichia, Eubacterium, Klebsiella, Lactobacillus, Pseudomonas and Staphylococcus (PMID: 19961416).

3,4-Dihydroxymandelic acid
3,4-Dihydroxymandelic acid, also known as DOMA or 3,4-dihydroxyphenylglycolate, belongs to the class of organic compounds known as catechols. Catechols are compounds containing a 1,2-benzenediol moiety. 3,4-Dihydroxymandelic acid exists in all living organisms, ranging from bacteria to humans. Within humans, 3,4-dihydroxymandelic acid participates in a number of enzymatic reactions. In particular, 3,4-dihydroxymandelic acid can be biosynthesized from 3,4-dihydroxymandelaldehyde through its interaction with the enzyme aldehyde dehydrogenase, dimeric nadp-preferring. In addition, 3,4-dihydroxymandelic acid and guaiacol can be converted into vanillylmandelic acid and pyrocatechol through the action of the enzyme catechol O-methyltransferase. In humans, 3,4-dihydroxymandelic acid is involved in the metabolic disorder called tyrosinemia type I. Outside of the human body, 3,4-Dihydroxymandelic acid has been detected, but not quantified in several different foods, such as yellow wax beans, soy beans, pomegranates, cucurbita (gourd), and daikon radish. 3,4-dihydroxymandelic acid, also known as 3,4-dihydroxyphenylglycolate or (3,4-dihydroxyphenyl)(hydroxy)acetic acid, is a member of the class of compounds known as catechols. Catechols are compounds containing a 1,2-benzenediol moiety. 3,4-dihydroxymandelic acid is soluble (in water) and a moderately acidic compound (based on its pKa). 3,4-dihydroxymandelic acid can be found in a number of food items such as lime, pitanga, sapodilla, and persimmon, which makes 3,4-dihydroxymandelic acid a potential biomarker for the consumption of these food products. 3,4-dihydroxymandelic acid can be found primarily in blood and urine, as well as in human nerve cells tissue. In humans, 3,4-dihydroxymandelic acid is involved in a couple of metabolic pathways, which include disulfiram action pathway and tyrosine metabolism. 3,4-dihydroxymandelic acid is also involved in several metabolic disorders, some of which include hawkinsinuria, alkaptonuria, dopamine beta-hydroxylase deficiency, and tyrosinemia, transient, of the newborn.

5,6-dihydrouracil
Dihydrouracil belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Dihydrouracil is an intermediate breakdown product of uracil. Dihydrouracil exists in all living organisms, ranging from bacteria to plants to humans. Within humans, dihydrouracil participates in a number of enzymatic reactions. In particular, dihydrouracil can be biosynthesized from uracil; which is mediated by the enzyme dihydropyrimidine dehydrogenase [NADP(+)]. The breakdown of uracil is a multistep reaction that leads to the production of beta-alanine. The reaction process begins with the enzyme known as dihydropyrimidine dehydrogenase (DHP), which catalyzes the reduction of uracil into dihydrouracil. Then the enzyme known as dihydropyrimidinase hydrolyzes dihydrouracil into N-carbamyl-beta-alanine. Finally, beta-ureidopropionase catalyzes the conversion of N-carbamyl-beta-alanine into beta-alanine. There is at least one metabolic disorder that is associated with altered levels of dihydrouracil. In particular, dihydropyrimidinase deficiency is an inborn metabolic disorder that leads to highly increased concentrations of dihydrouracil and 5,6-dihydrothymine, and moderately increased concentrations of uracil and thymine in urine. Dihydropyrimidinase deficiency can cause neurological and gastrointestinal problems in some affected individuals (OMIM: 222748). In particular, patients with dihydropyrimidinase deficiency exhibit a number of neurological abnormalities including intellectual disability, seizures, weak muscle tone (hypotonia), an abnormally small head size (microcephaly), and autistic behaviours that affect communication and social interaction. Gastrointestinal problems that occur in dihydropyrimidinase deficiency include backflow of acidic stomach contents into the esophagus (gastroesophageal reflux) and recurrent episodes of vomiting. 3,4-dihydrouracil, also known as 2,4-dioxotetrahydropyrimidine or 5,6-dihydro-2,4-dihydroxypyrimidine, is a member of the class of compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 3,4-dihydrouracil is soluble (in water) and a very weakly acidic compound (based on its pKa). 3,4-dihydrouracil can be found in a number of food items such as colorado pinyon, rocket salad (sspecies), wax gourd, and boysenberry, which makes 3,4-dihydrouracil a potential biomarker for the consumption of these food products. 3,4-dihydrouracil can be found primarily in blood, cerebrospinal fluid (CSF), saliva, and urine, as well as throughout most human tissues. 3,4-dihydrouracil exists in all living organisms, ranging from bacteria to humans. In humans, 3,4-dihydrouracil is involved in a couple of metabolic pathways, which include beta-alanine metabolism and pyrimidine metabolism. 3,4-dihydrouracil is also involved in several metabolic disorders, some of which include UMP synthase deficiency (orotic aciduria), dihydropyrimidinase deficiency, ureidopropionase deficiency, and carnosinuria, carnosinemia. Moreover, 3,4-dihydrouracil is found to be associated with dihydropyrimidine dehydrogenase deficiency and hypertension.

3-methyl-2-oxovalerate
3-Methyl-2-oxovaleric acid (CAS: 1460-34-0) is an abnormal metabolite that arises from the incomplete breakdown of branched-chain amino acids. 3-Methyl-2-oxovaleric acid is a neurotoxin, an acidogen, and a metabotoxin. A neurotoxin causes damage to nerve cells and nerve tissues. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of 3-methyl-2-oxovaleric acid are associated with maple syrup urine disease. MSUD is a metabolic disorder caused by a deficiency of the branched-chain alpha-keto acid dehydrogenase complex (BCKDC), leading to a buildup of the branched-chain amino acids (leucine, isoleucine, and valine) and their toxic by-products (ketoacids) in the blood and urine. The symptoms of MSUD often show in infancy and lead to severe brain damage if untreated. MSUD may also present later depending on the severity of the disease. If left untreated in older individuals, during times of metabolic crisis, symptoms of the condition include uncharacteristically inappropriate, extreme, or erratic behaviour and moods, hallucinations, anorexia, weight loss, anemia, diarrhea, vomiting, dehydration, lethargy, oscillating hypertonia and hypotonia, ataxia, seizures, hypoglycemia, ketoacidosis, opisthotonus, pancreatitis, rapid neurological decline, and coma. In maple syrup urine disease, the brain concentration of branched-chain ketoacids can increase 10- to 20-fold. This leads to a depletion of glutamate and a consequent reduction in the concentration of brain glutamine, aspartate, alanine, and other amino acids. The result is a compromise of energy metabolism because of a failure of the malate-aspartate shuttle and a diminished rate of protein synthesis (PMID: 15930465). 3-Methyl-2-oxovaleric acid is a keto-acid, which is a subclass of organic acids. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of untreated MSUD. Many affected children with organic acidemias experience intellectual disability or delayed development. (s)-3-methyl-2-oxopentanoate, also known as (3s)-2-oxo-3-methyl-N-valeric acid or (S)-omv, belongs to short-chain keto acids and derivatives class of compounds. Those are keto acids with an alkyl chain the contains less than 6 carbon atoms. Thus, (s)-3-methyl-2-oxopentanoate is considered to be a fatty acid lipid molecule (s)-3-methyl-2-oxopentanoate is slightly soluble (in water) and a weakly acidic compound (based on its pKa). (s)-3-methyl-2-oxopentanoate can be found in a number of food items such as bean, prickly pear, wild leek, and nutmeg, which makes (s)-3-methyl-2-oxopentanoate a potential biomarker for the consumption of these food products (s)-3-methyl-2-oxopentanoate may be a unique S.cerevisiae (yeast) metabolite.

Penicillamine
Penicillamine is only found in individuals that have used or taken this drug. It is the most characteristic degradation product of the penicillin antibiotics. It is used as an antirheumatic and as a chelating agent in Wilsons disease. [PubChem]Penicillamine is a chelating agent recommended for the removal of excess copper in patients with Wilsons disease. From in vitro studies which indicate that one atom of copper combines with two molecules of penicillamine. Penicillamine also reduces excess cystine excretion in cystinuria. This is done, at least in part, by disulfide interchange between penicillamine and cystine, resulting in formation of penicillamine-cysteine disulfide, a substance that is much more soluble than cystine and is excreted readily. Penicillamine interferes with the formation of cross-links between tropocollagen molecules and cleaves them when newly formed. The mechanism of action of penicillamine in rheumatoid arthritis is unknown although it appears to suppress disease activity. Unlike cytotoxic immunosuppressants, penicillamine markedly lowers IgM rheumatoid factor but produces no significant depression in absolute levels of serum immunoglobulins. Also unlike cytotoxic immunosuppressants which act on both, penicillamine in vitro depresses T-cell activity but not B-cell activity.

Formic acid
Formic acid is the simplest carboxylic acid. Formate is an intermediate in normal metabolism. It takes part in the metabolism of one-carbon compounds and its carbon may appear in methyl groups undergoing transmethylation. It is eventually oxidized to carbon dioxide. Formate is typically produced as a byproduct in the production of acetate. It is responsible for both metabolic acidosis and disrupting mitochondrial electron transport and energy production by inhibiting cytochrome oxidase activity, the terminal electron acceptor of the electron transport chain. Cell death from cytochrome oxidase inhibition by formate is believed to result partly from depletion of ATP, reducing energy concentrations so that essential cell functions cannot be maintained. Furthermore, inhibition of cytochrome oxidase by formate may also cause cell death by increased production of cytotoxic reactive oxygen species (ROS) secondary to the blockade of the electron transport chain. In nature, formic acid is found in the stings and bites of many insects of the order Hymenoptera, including bees and ants. The principal use of formic acid is as a preservative and antibacterial agent in livestock feed. When sprayed on fresh hay or other silage, it arrests certain decay processes and causes the feed to retain its nutritive value longer. Urinary formate is produced by Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Enterobacter, Acinetobacter, Proteus mirabilis, Citrobacter frundii, Enterococcus faecalis, Streptococcus group B, Staphylococcus saprophyticus (PMID: 22292465). It is used as a flavouring adjunct, an animal feed additive, a brewing antiseptic and as a food preservative

Dimethylpropiothetin
Dimethylsulfoniopropionate, also known as dimethylpropiothetin or S-dimethylsulfonium propionic acid, is a member of the class of compounds known as carboxylic acid salts. Carboxylic acid salts are ionic derivatives of carboxylic acid. Dimethylsulfoniopropionate is slightly soluble (in water) and a weakly acidic compound (based on its pKa). Dimethylsulfoniopropionate can be found in a number of food items such as sugar apple, american butterfish, coriander, and oxheart cabbage, which makes dimethylsulfoniopropionate a potential biomarker for the consumption of these food products. Dimethylsulfoniopropionate (DMSP), is an organosulfur compound with the formula (CH3)2S+CH2CH2COO−. This zwitterionic metabolite can be found in marine phytoplankton, seaweeds, and some species of terrestrial and aquatic vascular plants. It functions as an osmolyte as well as several other physiological and environmental roles have also been identified. DMSP was first identified in the marine red alga Polysiphonia fastigiata by Frederick Challenger and Margaret Simpson (later Dr. Whitaker) .

Pregnanediol
Pregnanediol is an endogenous human testosterone metabolite. It can be detected in the urine of adults and newborns in variable concentrations. Pregnanediol is abnormally elevated in patients with cytochrome P450 (P450C17, steroid 17alpha-monooxygenase, EC 1.14.99.9) oxidoreductase deficiency (Antley-Bixler syndrome, PORD, OMIM: 201750). Antley-Bixler syndrome is a multiple congenital malformation syndrome with craniosynostosis, radiohumeral synostosis, femoral bowing, choanal atresia or stenosis, joint contractures, urogenital abnormalities, and often early death. An assay of urinary pregnanediol excretion provides an accurate indication of outcome in threatened miscarriage in 74 - 93\\\% percent of cases. Pregnanediol is one of the most important markers of pregnenolone administration, which can potentially be abused by athletes to maintain an equilibration of the steroidal environment after sex steroids administrations. Patients with recurrent vulvovaginal candidiasis have significantly lower levels of urinary pregnanediol (PMID: 126703, 16608896, 16906539, 1191599, 2905284, 15763596, 10360427, 11159778, 16687200). Pregnanediol excretion is low in women with suspected placental insufficiency and in women with uterine fibroma. Pregnanediol levels can change in endocrine disturbances such as hirsutism or Cushings syndrome, depending on the stage of the disease. Pregnanediol has been tried as a more reliable compound to measure in screening of urinary steroids when suspecting doping, due to its not significant isotopic fractionation that could lead to false positive results in anti-doping testing. 13C-Enrichment caused by a diet change might be a reason of concern in athletes that move around between places and might have a considerable change of diet between competitions. In contrast to the results obtained with the carbon isotopic ratio, the profiling of urinary testosterone/epitestosterone (T/E) ratios is found to be unaffected by a diet change (PMID: 16338181, 5172227, 13636945, 14440289). Pregnanediol is an endogenous human testosterone metabolite. It can be detected in adults and newborns urine in variable concentrations. Pregnanediol is abnormally elevated in patients with cytochrome P450 (P450C17, steroid 17alpha-monooxygenase, EC 1.14.99.9) oxidoreductase deficiency (Antley-Bixler syndrome, PORD, OMIM 201750). Antley-Bixler syndrome is a multiple congenital malformation syndrome with craniosynostosis, radiohumeral synostosis, femoral bowing, choanal atresia or stenosis, joint contractures, urogenital abnormalities and, often, early death. An assay of urinary pregnanediol excretion provides an accurate indication of outcome in threatened abortion in 74 - 93\\\% per cent of cases. Pregnanediol is one of the most important markers of pregnenolone administration, which can potentially be abused by athletes to maintain an equilibration of the steroidal environment after sex steroids administrations. Patients with recurrent vulvovaginal candidiasis have significantly lower levels of urinary pregnanediol.

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].
