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

Fumarate is converted by the enzyme fumarase to malate. Fumaric acid has recently been identified as an oncometabolite or an endogenous, cancer causing metabolite. High levels of this organic acid can be found in tumors or biofluids surrounding tumors. Its oncogenic action appears to due to its ability to inhibit prolyl hydroxylase-containing enzymes. In many tumours, oxygen availability becomes limited (hypoxia) very quickly due to rapid cell proliferation and limited blood vessel growth. The major regulator of the response to hypoxia is the HIF transcription factor (HIF-alpha). Under normal oxygen levels, protein levels of HIF-alpha are very low due to constant degradation, mediated by a series of post-translational modification events catalyzed by the prolyl hydroxylase domain-containing enzymes PHD1, 2 and 3, (also known as EglN2, 1 and 3) that hydroxylate HIF-alpha and lead to its degradation. All three of the PHD enzymes are inhibited by fumarate. Fumaric acid is found to be associated with fumarase deficiency, which is an inborn error of metabolism. It is also a metabolite of Aspergillus. Produced industrially by fermentation of Rhizopus nigricans, or manufactured by catalytic or thermal isomerisation of maleic anhydride or maleic acid. Used as an antioxidant, acidulant, leavening agent and flavouring agent in foods. Present in raw lean fish. Dietary supplement. Used in powdered products since fumaric acid is less hygroscopic than other acids. A precursor to L-malate in the Krebs tricarboxylic acid cycle. It is formed by the oxidation of succinate by succinate dehydrogenase (wikipedia). Fumaric acid is also found in garden tomato, papaya, wild celery, and star fruit. Fumaric acid.

Argininosuccinic acid disodium

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

C10H18N4O6 (290.1226)


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

Asparagine

(2S)-2-Amino-3-carbamoylpropanoic acid

C4H8N2O3 (132.0535)


Asparagine (Asn) or L-asparagine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-asparagine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Asparagine is found in all organisms ranging from bacteria to plants to animals. In humans, asparagine is not an essential amino acid, which means that it can be synthesized from central metabolic pathway intermediates in humans and is not required in the diet. The precursor to asparagine is oxaloacetate. Oxaloacetate is converted to aspartate using a transaminase enzyme. This enzyme transfers the amino group from glutamate to oxaloacetate producing alpha-ketoglutarate and aspartate. The enzyme asparagine synthetase produces asparagine, AMP, glutamate, and pyrophosphate from aspartate, glutamine, and ATP. In the asparagine synthetase reaction, ATP is used to activate aspartate, forming beta-aspartyl-AMP. Glutamine donates an ammonium group which reacts with beta-aspartyl-AMP to form asparagine and free AMP. Since the asparagine side chain can make efficient hydrogen bond interactions with the peptide backbone, asparagines are often found near the beginning and end of alpha-helices, and in turn motifs in beta sheets. Its role can be thought as "capping" the hydrogen bond interactions which would otherwise need to be satisfied by the polypeptide backbone. Asparagine also provides key sites for N-linked glycosylation, a modification of the protein chain that is characterized by the addition of carbohydrate chains. A reaction between asparagine and reducing sugars or reactive carbonyls produces acrylamide (acrylic amide) in food when heated to sufficient temperature (i.e. baking). These occur primarily in baked goods such as French fries, potato chips, and roasted coffee. Asparagine was first isolated in 1806 from asparagus juice --hence its name. Asparagine was the first amino acid to be isolated. The smell observed in the urine of some individuals after the consumption of asparagus is attributed to a byproduct of the metabolic breakdown of asparagine, asparagine-amino-succinic-acid monoamide. However, some scientists disagree and implicate other substances in the smell, especially methanethiol. [Spectral] L-Asparagine (exact mass = 132.05349) and L-Aspartate (exact mass = 133.03751) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX.

(2R)-4-({[({[(2R,3S,4R,5R)-5-(6-amino-9H-purin-9-yl)-4-hydroxy-3-(phosphonooxy)oxolan-2-yl]methoxy}(hydroxy)phosphoryl)oxy](hydroxy)phosphoryl}oxy)-N-(2-{[2-(butanoylsulfanyl)ethyl]-C-hydroxycarbonimidoyl}ethyl)-2-hydroxy-3,3-dimethylbutanimidic acid

C25H42N7O17P3S (837.1571)


Butyryl-coa, also known as 4:0-coa or butanoyl-coa, is a member of the class of compounds known as acyl coas. Acyl coas are organic compounds containing a coenzyme A substructure linked to an acyl chain. Thus, butyryl-coa is considered to be a fatty ester lipid molecule. Butyryl-coa is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). Butyryl-coa can be synthesized from coenzyme A and butyric acid. Butyryl-coa is also a parent compound for other transformation products, including but not limited to, (2S,3S)-3-hydroxy-2-methylbutanoyl-CoA, acetoacetyl-CoA, and 2-methylacetoacetyl-CoA. Butyryl-coa can be found in a number of food items such as wild carrot, persian lime, redcurrant, and arrowroot, which makes butyryl-coa a potential biomarker for the consumption of these food products. Butyryl-coa may be a unique E.coli metabolite.

   

Dihydroorotic acid

(S)-2,6-dioxo-hexahydro-Pyrimidine-4-carboxylic acid

C5H6N2O4 (158.0328)


4,5-Dihydroorotic acid, also known as dihydroorotate or hydroorotate is a pyrimidinemonocarboxylic acid that results from the base-catalysed cyclisation of N-alpha-carbethoxyasparagine. It is classified as a secondary amide, a monocarboxylic acid, a pyrimidinemonocarboxylic acid and a N-acylurea. 4,5-Dihydroorotic acid is a derivative of orotic acid which serves as an intermediate in pyrimidine biosynthesis. 4,5-Dihydroorotic acid exists in all living species, ranging from bacteria to plants to humans. 4,5-Dihydroorotic acid is synthesized by the enzyme known as Dihydroorotase (EC 3.5.2.3) which converts carbamoyl aspartic acid into 4,5-dihydroorotic acid as part of the de novo pyrimidine biosynthesis pathway (PMID: 13163076). 4,5-Dihydroorotic acid is also a substrate for the enzyme known as dihydroorotate dehydrogenase (DHODH). In mammalian species, DHODH catalyzes the fourth step in the de novo pyrimidine biosynthesis pathway, which involves the ubiquinone-mediated oxidation of dihydroorotate to orotate and the reduction of flavin mononucleotide (FMN) to dihydroflavin mononucleotide (FMNH2). Inhibition of DHODH activity with teriflunomide (an immunomodulatory drug) or expression with RNA interference results in reduced ROS generation and consequent apoptosis of transformed skin and prostate epithelial cells. Mutations in the DHOD gene have been shown to cause Miller syndrome, also known as Genee-Wiedemann syndrome, Wildervanck-Smith syndrome or post-axial acrofacial dystosis (PMID: 19915526). 4,5-Dihydroorotic acid is a substrate of the enzyme orotate reductase [EC 1.3.1.14], which is part of the pyrimidine metabolism pathway. (KEGG) Dihydroorotate is oxidized by Dihydroorotate dehydrogenases (DHODs) to orotate. These dehydrogenases use their FMN (flavin mononucleotide) prosthetic group to abstract a hydride equivalent from C6 to deprotonate C5 [HMDB] L-Dihydroorotic acid can reversibly hydrolyze to yield the acyclic L-ureidosuccinic acid by dihydrowhey enzyme[1].

   

Metanephrine

4-[1-hydroxy-2-(methylamino)ethyl]-2-methoxyphenol

C10H15NO3 (197.1052)


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

C4H8N2O3 (132.0535)


The simplest peptide, made of two glycine molecules; used in the synthesis of more complicated peptides. Glycine is a simple, nonessential amino acid, although experimental animals show reduced growth on low-glycine diets. The average adult ingests 3 to 5 grams of glycine daily. Glycine is involved in the bodys production of DNA, phospholipids and collagen, and in release of energy. Glycine levels are effectively measured in plasma in both normal patients and those with inborn errors of glycine metabolism. (http://www.dcnutrition.com/AminoAcids/) Nonketotic hyperglycinaemia (OMIM 606899) is an autosomal recessive condition caused by deficient enzyme activity of the glycine cleavage enzyme system (EC 2.1.1.10). The glycine cleavage enzyme system comprises four proteins: P-, T-, H- and L-proteins (EC 1.4.4.2, EC 2.1.2.10 and EC 1.8.1.4 for P-, T- and L-proteins). Mutations have been described in the GLDC (OMIM 238300), AMT (OMIM 238310), and GCSH (OMIM 238330) genes encoding the P-, T-, and H-proteins respectively. The glycine cleavage system catalyses the oxidative conversion of glycine into carbon dioxide and ammonia, with the remaining one-carbon unit transferred to folate as methylenetetrahydrofolate. It is the main catabolic pathway for glycine and it also contributes to one-carbon metabolism. Patients with a deficiency of this enzyme system have increased glycine in plasma, urine and cerebrospinal fluid (CSF) with an increased CSF: plasma glycine ratio.

L-Cystine

(2R)-2-amino-3-[[(2R)-2-amino-2-carboxyethyl]disulfanyl]propanoic acid

C6H12N2O4S2 (240.0238)


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

Saccharopine

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

C11H20N2O6 (276.1321)


Saccharopine is an intermediate in the degradation of lysine, formed by the condensation of lysine and alpha-ketoglutarate. The saccharopine pathway is the main route for lysine degradation in mammals, and its first two reactions are catalyzed by enzymatic activities known as lysine-oxoglutarate reductase (LOR) and saccharopine dehydrogenase (SDH), which reside on a single bifunctional polypeptide (LOR/SDH) (EC 1.5.1.8). The reactions involved with saccharopine dehydrogenases have very strict substrate specificity for L-lysine, 2-oxoglutarate, and NADPH. LOR/SDH has been detected in a number of mammalian tissues, mainly in the liver and kidney, contributing not only to the general nitrogen balance in the organism but also to the controlled conversion of lysine into ketone bodies. A tetrameric form has also been observed in human liver and placenta. LOR activity has also been detected in brain mitochondria during embryonic development, and this opens up the question of whether or not lysine degradation has any functional significance during brain development. As a result, there is now a new focus on the nutritional requirements for lysine in gestation and infancy. Finally, LOR and/or SDH deficiencies seem to be involved in a human autosomal genetic disorder known as familial hyperlysinemia, which is characterized by serious defects in the functioning of the nervous system and characterized by a deficiency in lysine-ketoglutarate reductase, saccharopine dehydrogenase, and saccharopine oxidoreductase activities. Saccharopinuria (high amounts of saccharopine in the urine) and saccharopinemia (an excess of saccharopine in the blood) are conditions present in some inherited disorders of lysine degradation (PMID: 463877, 10567240, 10772957, 4809305). If present in sufficiently high levels, saccharopine can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Saccharopine is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). Many affected children with organic acidemias experience intellectual disability or delayed development. Amino acid from Saccharomyces cerevisiae and Neurospora crassaand is also found in mushrooms and seeds

   

1-methyl-4-imidazoleacetate

Methylimidazoleacetic acid, hydrochloride

C6H8N2O2 (140.0586)


Methylimidazoleacetic acid is the main metabolite of histamine. This end product of histamine catabolism is formed by N-methylation in the imidazole ring to methylhistamine by histamine methyltransferase (EC 2.1.1.8) and a subsequent oxidative deamination in the side chain by type B monoamine oxidase (EC 1.4.3.4). Based on studies, it is known that as much as 70 to 80 percent of the histamine metabolized in the body is excreted in the urine as methylimidazoleacetic acid. Thus, urinary methylimidazoleacetic acid being the major and specific histamine metabolite is a clear marker of any changes in histamine metabolism in the body. The urinary excretion of methylimidazoleacetic acid is considered a reliable indicator of histamine turnover rate in the body. The excretion of methylimidazoleacetic acid is higher in men than in women. However, this gender difference is abolished when corrected for creatinine excretion. A possible explanation is that basal histamine turnover is related to body size. There is no significant difference in methylimidazoleacetic acid excretion between smokers and non-smokers when analyzing absolute values (mg/24 h). When using methylimidazoleacetic acid values corrected for creatinine excretion female smokers have significantly higher methylimidazoleacetic acid excretion compared to nonsmokers (PMID:11411609, 7130180, 10350179, 10202992).

N-acetylglutamate

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

C7H11NO5 (189.0637)


N-Acetyl-L-glutamic acid or N-Acetylglutamate, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetyl-L-glutamate can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetyl-L-glutamate is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-glutamic acid. N-Acetyl-L-glutamic acid is found in all organisms ranging from bacteria to plants to animals. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\\% of all human proteins and 68\\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetylglutamate can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free glutamic acid can also occur. In particular, N-Acetyl-L-glutamic acid can be biosynthesized from glutamate and acetylornithine by ornithine acetyltransferase, and from glutamic acid and acetyl-CoA by the enzyme known as N-acetylglutamate synthase. N-Acetyl-L-glutamic acid is the first intermediate involved in the biosynthesis of arginine in prokaryotes and simple eukaryotes and a regulator of the urea cycle in vertebrates. In vertebrates, N-acetylglutamic acid is the allosteric activator molecule to mitochondrial carbamyl phosphate synthetase I (CPSI) which is the first enzyme in the urea cycle. It triggers the production of the first urea cycle intermediate, a compound known as carbamyl phosphate. Notably the CPSI enzyme is inactive when N-acetylglutamic acid is not present. A deficiency in N-acetyl glutamate synthase or a genetic mutation in the gene coding for the enzyme will lead to urea cycle failure in which ammonia is not converted to urea, but rather accumulated in the blood leading to the condition called Type I hyperammonemia. Excessive amounts N-acetyl amino acids can be detected in the urine with individuals with aminoacylase I deficiency, a genetic disorder (PMID: 16465618). These include N-acetylalanine (as well as N-acetylserine, N-acetylglutamine, N-acetylglutamate, N-acetylglycine, N-acetylmethionine and smaller amounts of N-acetylthreonine, N-acetylleucine, N-acetylvaline and N-acetylisoleucine. Aminoacylase I is a soluble homodimeric zinc binding enzyme that catalyzes the formation of free aliphatic amino acids from N-acetylated precursors. In humans, Aminoacylase I is encoded by the aminoacylase 1 gene (ACY1) on chromosome 3p21 that consists of 15 exons (OMIM 609924). Individuals with aminoacylase I deficiency w... N-acetyl-l-glutamate, also known as L-N-acetylglutamic acid or ac-glu-oh, belongs to glutamic acid and derivatives class of compounds. Those are compounds containing glutamic acid or a derivative thereof resulting from reaction of glutamic acid at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-acetyl-l-glutamate is soluble (in water) and a weakly acidic compound (based on its pKa). N-acetyl-l-glutamate can be found in a number of food items such as cardoon, almond, butternut squash, and avocado, which makes N-acetyl-l-glutamate a potential biomarker for the consumption of these food products. N-acetyl-l-glutamate may be a unique S.cerevisiae (yeast) metabolite. Acquisition and generation of the data is financially supported in part by CREST/JST.

Pipecolic acid

Pipecolic acid, 14C-labeled CPD, (+,-)-isomer

C6H11NO2 (129.079)


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

Pyridoxal

3-Hydroxy-5-(hydroxymethyl)-2-methylpyridine-4-carboxaldehyde

C8H9NO3 (167.0582)


Pyridoxal is a pyridinecarbaldehyde that is pyridine-4-carbaldehyde bearing methyl, hydroxy and hydroxymethyl substituents at positions 2, 3 and 5 respectively. Pyridoxal, also known as pyridoxaldehyde, belongs to the class of organic compounds known as pyridoxals and derivatives. Pyridoxals and derivatives are compounds containing a pyridoxal moiety, which consists of a pyridine ring substituted at positions 2, 3, 4, and 5 by a methyl group, a hydroxyl group, a carbaldehyde group, and a hydroxymethyl group, respectively. Pyridoxal is one form of vitamin B6. Pyridoxal exists in all living species, ranging from bacteria to humans. In humans, pyridoxal is involved in glycine and serine metabolism. Pyridoxal has been detected, but not quantified in several different foods, such as sourdoughs, lichee, arctic blackberries, watercress, and cottonseeds. Some medically relevant bacteria, such as those in the genera Granulicatella and Abiotrophia, require pyridoxal for growth. This nutritional requirement can lead to the culture phenomenon of satellite growth. In in vitro culture, these pyridoxal-dependent bacteria may only grow in areas surrounding colonies of bacteria from other genera ("satellitism") that are capable of producing pyridoxal. Pridoxal has a role as a cofactor, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite.

Tolmetin is only found in individuals that have used or taken this drug. It is a non-steroidal anti-inflammatory agent (anti-inflammatory agents, NON-steroidal) similar in mode of action to indomethacin. [PubChem]The mode of action of tolmetin is not known. However, studies in laboratory animals and man have demonstrated that the anti-inflammatory action of tolmetin is not due to pituitary-adrenal stimulation. Tolmetin inhibits prostaglandin synthetase in vitro and lowers the plasma level of prostaglandin E in man. This reduction in prostaglandin synthesis may be responsible for the anti-inflammatory action. Tolmetin does not appear to alter the course of the underlying disease in man.

Itaconic acid

2-Hydroxy-3-naphthoyl-2-naphthylamine

C5H6O4 (130.0266)


Itaconic acid is a dicarboxylic acid that is methacrylic acid in which one of the methyl hydrogens is substituted by a carboxylic acid group. It has a role as a fungal metabolite and a human metabolite. It is a dicarboxylic acid and an olefinic compound. It derives from a succinic acid. It is a conjugate acid of an itaconate(2-). This dicarboxylic acid is a white solid that is soluble in water, ethanol, and acetone. Historically, itaconic acid was obtained by the distillation of citric acid, but currently it is produced by fermentation. The name itaconic acid was devised as an anagram of aconitic acid, another derivative of citric acid. Itaconic acid, also known as itaconate, belongs to the class of organic compounds known as branched fatty acids. These are fatty acids containing a branched chain. Itaconic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Since the 1960s, it is produced industrially by the fermentation of carbohydrates such as glucose or molasses using fungi such as Aspergillus itaconicus or Aspergillus terreus. For A. terreus the itaconate pathway is mostly elucidated. The generally accepted route for itaconate is via glycolysis, tricarboxylic acid cycle, and a decarboxylation of cis-aconitate to itaconate via cis-aconitate-decarboxylase. The smut fungus Ustilago maydis uses an alternative route. Cis-aconitate is converted to the thermodynamically favoured trans-aconitate via aconitate-Δ-isomerase (Adi1). trans-Aconitate is further decarboxylated to itaconate by trans-aconitate-decarboxylase (Tad1). Itaconic acid is also produced in cells of macrophage lineage. It was shown that itaconate is a covalent inhibitor of the enzyme isocitrate lyase in vitro. As such, itaconate may possess antibacterial activities against bacteria expressing isocitrate lyase (such as Salmonella enterica and Mycobacterium tuberculosis). It is also sythesized in the laboratory, where dry distillation of citric acid affords itaconic anhydride, which undergoes hydrolysis to itaconic acid. Itaconic acid. CAS Common Chemistry. CAS, a division of the American Chemical Society, n.d. https://commonchemistry.cas.org/detail?cas_rn=97-65-4 (retrieved 2024-07-01) (CAS RN: 97-65-4). Licensed under the Attribution-Noncommercial 4.0 International License (CC BY-NC 4.0). Itaconic acid, a precursor of polymers, chemicals, and fuels, can be synthesized by many fungi. Itaconic acid also is a macrophage-specific metabolite. Itaconic acid mediates crosstalk between macrophage metabolism and peritoneal tumors[1][2].

C21H35N7O13P2S (687.1489)


Dephospho-CoA, also known as 3-dephospho-CoA, belongs to the class of organic compounds known as purine ribonucleoside diphosphates. These are purine ribonucleosides with a diphosphate group linked to the ribose moiety. Thus, dephospho-CoA is considered to be a fatty ester lipid molecule. Dephospho-CoA is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, dephospho-CoA has been detected, but not quantified in, several different foods, such as wild leeks, summer savouries, arctic blackberries, biscuits, and persimmons. This could make dephospho-CoA a potential biomarker for the consumption of these foods. Dephospho-CoA is an intermediate in pantothenate and CoA biosynthesis. It is a substrate for bifunctional coenzyme A synthase which contains the dephospho-CoA kinase (EC 2.7.1.24). This enzyme catalyzes the final step in CoA biosynthesis: the phosphorylation of the 3-hydroxyl group of ribose using ATP as a phosphate donor. The reaction is ATP + 3-dephospho-CoA = ADP + CoA. Dephospho-CoA is a substrate for Ectonucleotide pyrophosphatase/phosphodiesterase 1, Ectonucleotide pyrophosphatase/phosphodiesterase 3 and Ectonucleotide pyrophosphatase/phosphodiesterase 2. [HMDB]. Dephospho-CoA is found in many foods, some of which are cardamom, epazote, lemon balm, and mammee apple. Acquisition and generation of the data is financially supported in part by CREST/JST.

Glucosamine

(3R,4R,5S,6R)-3-Amino-6-(hydroxymethyl)oxane-2,4,5-triol

C6H13NO5 (179.0794)


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

Pyroglutamic acid

(S)-(-)-gamma-Butyrolactam-gamma-carboxylic acid

C5H7NO3 (129.0426)


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

Dialkyl phosphates are organic compounds containing a phosphate group that is linked to exactly two alkyl chain (e)-monocrotophos is slightly soluble (in water) and an extremely weak acidic compound (based on its pKa). Within the cell, (e)-monocrotophos is primarily located in the cytoplasm. It can also be found in the extracellular space (e)-monocrotophos is a non-carcinogenic (not listed by IARC) potentially toxic compound. 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).

Oleic acid

Emersol 221 low titer white oleic acid

C18H34O2 (282.2559)


Oleic acid (or 9Z)-Octadecenoic acid) is an unsaturated C-18 or an omega-9 fatty acid that is the most widely distributed and abundant fatty acid in nature. It occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. The name derives from the Latin word oleum, which means oil. Oleic acid is the most abundant fatty acid in human adipose tissue, and the second most abundant in human tissues overall, following palmitic acid. Oleic acid is a component of the normal human diet, being a part of animal fats and vegetable oils. Triglycerides of oleic acid represent the majority of olive oil (about 70\\\\%). Oleic acid triglycerides also make up 59–75\\\\% of pecan oil, 61\\\\% of canola oil, 36–67\\\\% of peanut oil, 60\\\\% of macadamia oil, 20–80\\\\% of sunflower oil, 15–20\\\\% of grape seed oil, sea buckthorn oil, 40\\\\% of sesame oil, and 14\\\\% of poppyseed oil. High oleic variants of plant sources such as sunflower (~80\\\\%) and canola oil (70\\\\%) also have been developed. consumption has been associated with decreased low-density lipoprotein (LDL) cholesterol, and possibly with increased high-density lipoprotein (HDL) cholesterol, however, the ability of oleic acid to raise HDL is still debated. Oleic acid may be responsible for the hypotensive (blood pressure reducing) effects of olive oil that is considered a health benefit. Oleic acid is used in manufacturing of surfactants, soaps, plasticizers. It is also used as an emulsifying agent in foods and pharmaceuticals. Oleic acid is used commercially in the preparation of oleates and lotions, and as a pharmaceutical solvent. Major constituent of plant oils e.g. olive oil (ca. 80\\\\%), almond oil (ca. 80\\\\%) and many others, mainly as glyceride.

Aicar, also known as 5-phosphoribosyl-5-amino-4-imidazolecarboxamide or 5-aminoimidazole-4-carboxamide ribotide, is a member of the class of compounds known as 1-ribosyl-imidazolecarboxamides. 1-ribosyl-imidazolecarboxamides are organic compounds containing the imidazole ring linked to a ribose ring through a 1-2 bond. Aicar is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Aicar can be found in a number of food items such as safflower, greenthread tea, common pea, and wild leek, which makes aicar a potential biomarker for the consumption of these food products. Aicar can be found primarily in saliva, as well as in human skeletal muscle tissue. Aicar exists in all living species, ranging from bacteria to humans. In humans, aicar is involved in few metabolic pathways, which include azathioprine action pathway, mercaptopurine action pathway, purine metabolism, and thioguanine action pathway. Aicar is also involved in several metabolic disorders, some of which include mitochondrial DNA depletion syndrome, purine nucleoside phosphorylase deficiency, xanthinuria type II, and gout or kelley-seegmiller syndrome. AICAR also known as ZMP is an analog of AMP that is capable of stimulating AMP-dependent protein kinase activity(AMPK). AICAR is an intermediate in the generation of inosine monophosphate. AICAR is being clinically used to treat and protect against cardiac ischemic injury. AICAR can enter cardiac cells to inhibit adenosine kinase and adenosine deaminase. It enhances the rate of nucleotide re-synthesis increasing adenosine generation from adenosine monophosphate only during conditions of myocardial ischemia. AICAR increases glucose uptake by inducing translocation of GLUT4 and/or by activating the p38 MAPK pathway. Acquisition and generation of the data is financially supported in part by CREST/JST.

D-Xylose

(3R,4S,5R)-Tetrahydro-2H-pyran-2,3,4,5-tetrol

C5H10O5 (150.0528)


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

Tizanidine

5-chloro-N-(4,5-dihydro-1H-imidazol-2-yl)-2,1,3-benzothiadiazol-4-amine

C9H8ClN5S (253.0189)


Tizanidine is a short-acting drug for the management of spasticity. Tizanidine is an agonist at a2-adrenergic receptor sites and presumably reduces spasticity by increasing presynaptic inhibition of motor neurons. In animal models, tizanidine has no direct effect on skeletal muscle fibers or the neuromuscular junction, and no major effect on monosynaptic spinal reflexes. The effects of tizanidine are greatest on polysynaptic pathways. The overall effect of these actions is thought to reduce facilitation of spinal motor neurons. Tizanidine has two major metabolites: (1) 5-chloro-4-(2-imidazolin-4-on-2-ylamino)-2,1,3-benzothiazdiazole and (2) 5-chloro-4-(2-imidazolin-4-on-2-ylamino)-2,1,3-benzothiadiazole (PMID: 9929503, 19961320).

Target: α2-adrenergic receptor Tizanidine is a drug that is used as a muscle relaxant. It is a centrally acting α2 adrenergic agonist. It is used to treat the spasms, cramping, and tightness of muscles caused by medical problems such as multiple sclerosis, ALS, spastic diplegia, back pain, or certain other injuries to the spine or central nervous system. It is also prescribed off-label for migraine headaches, as a sleep aid, and as an anticonvulsant. It is also prescribed for some symptoms of fibromyalgia. Tizanidine has been found to be as effective as other antispasmodic drugs and has superior tolerability to that of baclofen and diazepam. Tizanidine can be very strong even at the 2 mg dose and may cause hypotension, so caution is advised when it is used in patients who have a history of orthostatic hypotension, or when switching from gel cap to tablet form and vice versa. Tizanidine can occasionally cause liver damage, generally the hepatocellular type. Clinical trials show that up to 5\% of patients treated with tizanidine had elevated liver function test values, though symptoms disappeared upon withdrawal of the drug. Care should be used when first beginning treatment with tizanidine with regular liver tests for the first 6 months of treatment.

4-Hydroxybutyric acid

4-Hydroxybutyric acid monosodium salt

C4H8O3 (104.0473)


4-Hydroxybutyric acid (also known as gamma-hydroxybutyrate or GHB) is a precursor and a metabolite of gamma-aminobutyric acid (GABA). GHB acts as a central nervous system (CNS) neuromodulator, mediating its effects through GABA and GHB-specific receptors, or by affecting dopamine transmission (PMID: 16620539). GHB occurs naturally in all mammals, but its function remains unknown. GHB is labeled as an illegal drug in most countries, but it also is used as a legal drug (Xyrem) in patients with narcolepsy. It is used illegally (under the street names juice, liquid ecstasy, or G) as an intoxicant for increasing athletic performance and as a date rape drug. In high doses, GHB inhibits the CNS, inducing sleep and inhibiting the respiratory drive. In lower doses, its euphoriant effect predominates (PMID: 17658710). When present in sufficiently high levels, 4-hydroxybutyric acid can act as an acidogen, a neurotoxin, and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A neurotoxin is a compound that adversely affects neural cells and tissues. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of 4-hydroxybutyric acid are associated with two inborn errors of metabolism: glutaric aciduria II and succinic semialdehyde dehydrogenase deficiency (SSADH). SSADH deficiency leads to a 30-fold increase of GHB and a 2-4 fold increase of GABA in the brains of patients with SSADH deficiency as compared to normal brain concentrations of the compounds. As an acidogen, 4-hydroxybutyric 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. Many affected children with organic acidemias experience intellectual disability or delayed development. These are also the characteristic symptoms of the untreated IEMs mentioned above. Particularly for SSADH deficiency, the most common features observed include developmental delay, hypotonia, and intellectual disability. Nearly half of patients exhibit ataxia, seizures, behaviour problems, and hyporeflexia. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. As a neurotoxin, GHB appears to affect both GABA (a neurotransmitter) signaling and glutamate signaling (another neurotransmitter). Glutamine metabolism may also play a role in the pathophysiology of excessive levels of GHB. High levels of GHB have been shown to depress both the NMDA and AMPA/kainite receptor-mediated functions and may also alter glutamatergic excitatory synaptic transmission as well. 4-Hydroxybutyric acid is a microbial metabolite found in Aeromonas, Escherichia and Pseudomonas (PMID: 19434404). 4-hydroxybutyric acid may cause bradycardia and dyskinesias.

C10H13N4O8P (348.0471)


Inosinic acid, also known as inosine monophosphate, IMP, 5-inosinate or 5-IMP, belongs to the class of organic compounds known as purine ribonucleoside monophosphates. These are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. IMP is also classified as a nucleotide (a nucleoside monophosphate). Inosinic acid exists in all living species, ranging from bacteria to plants to humans. IMP is widely used as a flavor enhancer. In the food industry it is known as E number reference E630. Inosinic acid can be converted into various salts including disodium inosinate (E631), dipotassium inosinate (E632), and calcium inosinate (E633). These three inosinate compounds are used as flavor enhancers for the basic taste umami. These inosinate salts are mostly used in soups, sauces, and seasonings for the intensification and balance of the flavor of meat. Inosinic acid is typically obtained from chicken byproducts or other meat industry waste. Inosinic acid or IMP is important in metabolism. It is the ribonucleotide of hypoxanthine and the first nucleotide formed during the synthesis of purine nucleotides. It can also be formed by the deamination of adenosine monophosphate by AMP deaminase. GMP is formed by the inosinate oxidation to xanthylate (XMP). Within humans, inosinic acid participates in a number of enzymatic reactions. In particular, inosinic acid can be converted into phosphoribosyl formamidocarboxamide; which is catalyzed by the bifunctional purine biosynthesis protein. In addition, inosinic acid can be converted into xanthylic acid; which is catalyzed by the enzyme inosine-5-monophosphate dehydrogenase 1.

N2-acetyllysine

6-Amino-2-[(1-hydroxyethylidene)amino]hexanoate

C8H16N2O3 (188.1161)


N-alpha-Acetyl-L-lysine also known as Nalpha-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 its terminal nitrogen atom. N-alpha-Acetyl-L-lysine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-alpha-Acetyl-L-lysine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-lysine. Unlike L-lysine, acetylated lysine derivatives such as N-alpha-Acetyl-L-lysine are zwitterionic compounds. These are molecules that contains an equal number of positively- and negatively-charged functional groups. N-alpha-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 by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\% of all human proteins and 68\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-alpha-Acetyl-L-lysine can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free lysine can also occur. In particular, N-alpha-Acetyl-L-lysine can be biosynthesized from L-lysine and acetyl-CoA via the enzyme known as Lysine N-acetyltransferase. Individuals with hyperlysinaemia due to L-lysine alpha-ketoglutarate reductase deficiency will excrete high levels of N-alpha-Acetyl-L-lysine in their urine (PMID: 116084). L-lysine alpha-ketoglutarate reductase deficiency, if untreated, can lead to neurological and behavioral deficits (PMID: 116084). 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). Acetyl-L-lysine is an endogenous metabolite.

Meta-Tyrosine, or M-Tyrosine for short, is a natural weed suppressant found in certain Fine fescue grass. M-tyrosine exudes out of the grass plants roots and is then absorbed by neighbouring weed seedlings. The weed plants will either die or be stunted from the toxic acid. DL-m-Tyrosine shows effects on Arabidopsis root growth. Carbidopa combination with DL-m-tyrosine shows a potent hypotensive effect[1][2].

   

5,6-dihydrouracil

5,6-Dihydro-2,4(1H,3H)-pyrimidinedione

C4H6N2O2 (114.0429)


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

alpha-keto-beta-Methyl-n-valeric acid

C6H10O3 (130.063)


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.

Decanoylcarnitine (C10)

(3R)-3-(decanoyloxy)-4-(trimethylazaniumyl)butanoate

C17H33NO4 (315.2409)


Decanoylcarnitine is a member of the class of compounds known as acylcarnitines. More specifically, it is a decanoic acid ester of carnitine. Acylcarnitines were first discovered in the 1940s (PMID: 13825279 ). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. Decanoylcarnitine is therefore classified as a medium chain AC. As a medium-chain acylcarnitine decanoylcarnitine is somewhat less abundant than short-chain acylcarnitines. These are formed either through esterification with L-carnitine or through the peroxisomal metabolism of longer chain acylcarnitines (PMID: 30540494 ). Many medium-chain acylcarnitines can serve as useful markers for inherited disorders of fatty acid metabolism. In particular decanoylcarnitine is elevated in the blood or plasma of individuals with obesity in adolescence (PMID: 26910390 ). It is also decreased in the blood or plasma of individuals with adolescent idiopathic scoliosis (PMID: 26928931 ). Carnitine octanoyltransferase (CrOT, EC:2.3.1.137) is responsible for the synthesis of all medium-chain (MCAC, C5-C12) and medium-length branched-chain acylcarnitines in peroxisomes (PMID: 10486279 ). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews]. Acylcarnitine useful in the diagnosis of fatty acid oxidation disorders and differentiation between biochemical phenotypes of medium-chain acyl-CoA dehydrogenase (MCAD) deficiency deficiencyoxidation disorders.(PMID: 12385891) [HMDB]

C5H7NO2 (113.0477)


1-Pyrroline-5-carboxylic acid (CAS: 2906-39-0) is an enamine or an imino acid that forms upon the spontaneous dehydration of L-glutamate gamma-semialdehyde in aqueous solutions. The stereoisomer (S)-1-pyrroline-5-carboxylate is an intermediate in glutamate metabolism, arginine degradation, and proline biosynthesis and degradation. It can also be converted into or be formed from three amino acids: L-glutamate, L-ornithine, and L-proline. In particular, it is synthesized via the oxidation of proline by pyrroline-5-carboxylate reductase 1 (PYCR1) (EC 1.5.1.2) or by proline dehydrogenase (PRODH) (EC 1.5.99.8). It is hydrolyzed into L-glutamate by delta-1-pyrroline-5-carboxylate dehydrogenase (ALDH4A1) (EC 1.5.1.12). It is also one of the few metabolites that can act as a precursor to other metabolites of both the urea cycle and the tricarboxylic acid (TCA) cycle. Under certain conditions, pyrroline-5-carboxylate can act as a neurotoxin and a metabotoxin. A neurotoxin causes damage to nerve cells and nerve tissues. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of pyrroline-5-carboxylate are associated with at least five inborn errors of metabolism, including hyperprolinemia type I, hyperprolinemia type II, iminoglycinuria, prolinemia type II, and pyruvate carboxylase deficiency. Hyperprolinemia type II results in high levels of pyrroline-5-carboxylate. People with hyperprolinemia type II have signs and symptoms that vary in severity, but they are more likely than type I to have seizures or intellectual disability. Pyrroline-5-carboxylate is highly reactive and excess quantities have been shown to cause cell death and apoptosis (PMID: 15548746).

Acetoacetate

Acetoacetic acid, calcium salt

C4H6O3 (102.0317)


Acetoacetic acid (AcAc) is a weak organic acid that can be produced in the human liver under certain conditions of poor metabolism leading to excessive fatty acid breakdown (diabetes mellitus leading to diabetic ketoacidosis). It is then partially converted into acetone by decarboxylation and excreted either in urine or through respiration. Persistent mild hyperketonemia is a common finding in newborns. Ketone bodies serve as an indispensable source of energy for extrahepatic tissues, especially the brain and lung of developing rats. Another important function of ketone bodies is to provide acetoacetyl-CoA and acetyl-CoA for synthesis of cholesterol, fatty acids, and complex lipids. During the early postnatal period, acetoacetate and beta-hydroxybutyrate are preferred over glucose as substrates for synthesis of phospholipids and sphingolipids in accord with requirements for brain growth and myelination. Thus, during the first two weeks of postnatal development, when the accumulation of cholesterol and phospholipids accelerates, the proportion of ketone bodies incorporated into these lipids increases. On the other hand, an increased proportion of ketone bodies are utilized for cerebroside synthesis during the period of active myelination. In the lung, AcAc serves better than glucose as a precursor for the synthesis of lung phospholipids. The synthesized lipids, particularly dipalmityl phosphatidylcholine, are incorporated into surfactant, and thus have a potential role in supplying adequate surfactant lipids to maintain lung function during the early days of life (PMID: 3884391). The acid is also present in the metabolism of those undergoing starvation or prolonged physical exertion as part of gluconeogenesis. When ketone bodies are measured by way of urine concentration, acetoacetic acid, along with beta-hydroxybutyric acid or acetone, is what is detected.

   

Cytidine triphosphate

({[({[(2R,3S,4R,5R)-5-(4-amino-2-oxo-1,2-dihydropyrimidin-1-yl)-3,4-dihydroxyoxolan-2-yl]methoxy}(hydroxy)phosphoryl)oxy](hydroxy)phosphoryl}oxy)phosphonic acid

C9H16N3O14P3 (482.9845)


Cytidine triphosphate (CTP), also known as 5-CTP, is pyrimidine nucleoside triphosphate. Formally, CTP is an ester of cytidine and triphosphoric acid. It belongs to the class of organic compounds known as pentose phosphates. These are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. CTP, much like ATP, consists of a base (cytosine), a ribose sugar, and three phosphate groups. CTP is a high-energy molecule similar to ATP, but its role as an energy coupler is limited to a much smaller subset of metabolic reactions. CTP exists in all living species, ranging from bacteria to plants to humans and is used in the synthesis of RNA via RNA polymerase. Another enzyme known as cytidine triphosphate synthetase (CTPS) mediates the conversion of uridine triphosphate (UTP) into cytidine triphosphate (CTP) which is the rate-limiting step of de novo CTP biosynthesis. CTPS catalyzes a complex set of reactions that include the ATP-dependent transfer of the amide nitrogen from glutamine (i.e., glutaminase reaction) to the C-4 position of UTP to generate CTP. GTP stimulates the glutaminase reaction by accelerating the formation of a covalent glutaminyl enzyme intermediate. CTPS activity regulates the intracellular rates of RNA synthesis, DNA synthesis, and phospholipid synthesis. CTPS is an established target for a number of antiviral, antineoplastic, and antiparasitic drugs. CTP also acts as an inhibitor of the enzyme known as aspartate carbamoyltransferase, which is used in pyrimidine biosynthesis. CTP also reacts with nitrogen-containing alcohols to form coenzymes that participate in the formation of phospholipids. In particular, CTP is the direct precursor of the activated, phospholipid pathway intermediates CDP-diacylglycerol, CDP-choline, and CDP-ethanolamine ((PMID: 18439916). CDP-diacylglycerol is the source of the phosphatidyl moiety for phosphatidylserine, phosphatidylethanolamine, and phosphatidylcholine (synthesized by way of the CDP-diacylglycerol pathway) as well as phosphatidylglycerol, cardiolipin, and phosphatidylinositol (PMID: 18439916). Cytidine triphosphate, also known as 5-ctp or cytidine 5-triphosphoric acid, is a member of the class of compounds known as pentose phosphates. Pentose phosphates are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. Cytidine triphosphate is soluble (in water) and an extremely strong acidic compound (based on its pKa). Cytidine triphosphate can be found in a number of food items such as lowbush blueberry, black radish, american pokeweed, and cherry tomato, which makes cytidine triphosphate a potential biomarker for the consumption of these food products. Cytidine triphosphate can be found primarily in cellular cytoplasm, as well as throughout all human tissues. Cytidine triphosphate exists in all living species, ranging from bacteria to humans. In humans, cytidine triphosphate is involved in several metabolic pathways, some of which include cardiolipin biosynthesis cl(i-14:0/i-17:0/i-16:0/i-21:0), cardiolipin biosynthesis cl(a-13:0/a-21:0/i-22:0/i-17:0), phosphatidylethanolamine biosynthesis PE(18:2(9Z,12Z)/24:0), and cardiolipin biosynthesis cl(i-13:0/a-21:0/a-15:0/i-16:0). Cytidine triphosphate is also involved in several metabolic disorders, some of which include sialuria or french type sialuria, tay-sachs disease, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and g(m2)-gangliosidosis: variant B, tay-sachs disease. Cytidine triphosphate is a high-energy molecule similar to ATP, but its role as an energy coupler is limited to a much smaller subset of metabolic reactions. Cytidine triphosphate is a coenzyme in metabolic reactions like the synthesis of glycerophospholipids and glycosylation of proteins . Cytidine 5′-triphosphate (Cytidine triphosphate; 5'-CTP) is a nucleoside triphosphate and serves as a building block for nucleotides and nucleic acids, lipid biosynthesis. Cytidine triphosphate synthase can catalyze the formation of cytidine 5′-triphosphate from uridine 5′-triphosphate (UTP). Cytidine 5′-triphosphate is an essential biomolecule?in the de novo?pyrimidine biosynthetic pathway in?T. gondii[1].

   

Nicotinic acid adenine dinucleotide

[C21H27N6O15P2]+ (665.101)


Nicotinic acid adenine dinucleotide, also known as deamido-NAD or NAAD, belongs to the class of organic compounds known as (5->5)-dinucleotides. These are dinucleotides where the two bases are connected via a (5->5)-phosphodiester linkage. NAAD is possibly soluble (in water) and a strong basic compound (based on its pKa). NAAD exists in all living species, ranging from bacteria to humans. L-Glutamine and NAAD can be converted into L-glutamic acid and NAD; which is catalyzed by the enzyme glutamine-dependent nad(+) synthetase. In humans, NAAD is involved in the nicotinate and nicotinamide metabolism pathway. NAAD is also involved in the metabolic disorder called succinic semialdehyde dehydrogenase deficiency. Outside of the human body, NAAD has been detected, but not quantified in, several different foods, such as japanese walnuts, cauliflowers, sparkleberries, komatsuna, and macadamia nut (m. tetraphylla). This could make NAAD a potential biomarker for the consumption of these foods. NAAD is the product of the degradation of Nicotinic acid adenine dinucleotide phosphate (NAADP) by a Ca2+-sensitive phosphatase. NAADP is a Ca2+-mobilizing second messenger which is synthesized, in response to extracellular stimuli, via the base-exchange reaction by an ADP-ribosyl cyclase (ARC) family members (such as CD38). NAADP binds to and opens Ca2+ channels on intracellular organelles, thereby increasing the intracellular Ca2+ concentration which, in turn, modulates a variety of cellular processes. Structurally, NAADP it is a dinucleotide that only differs from the house-keeping enzyme cofactor, NADP, by a hydroxyl group (replacing the nicotinamide amino group) and yet this minor modification converts it into the most potent Ca2+-mobilizing second messenger yet described. NAADP may also be broken down to 2-phosphoadenosine diphosphoribose (ADPRP) by CD38 or reduced to NAADPH. Deamido-nad(+), also known as deamidonicotinamide adenine dinucleoetide, is a member of the class of compounds known as (5->5)-dinucleotides (5->5)-dinucleotides are dinucleotides where the two bases are connected via a (5->5)-phosphodiester linkage. Deamido-nad(+) is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Deamido-nad(+) can be found in a number of food items such as garden tomato, sea-buckthornberry, pitanga, and japanese walnut, which makes deamido-nad(+) a potential biomarker for the consumption of these food products. Deamido-nad(+) exists in all living species, ranging from bacteria to humans. In humans, deamido-nad(+) is involved in few metabolic pathways, which include glutamate metabolism, homocarnosinosis, and nicotinate and nicotinamide metabolism. Deamido-nad(+) is also involved in few metabolic disorders, which include 2-hydroxyglutric aciduria (D and L form), 4-hydroxybutyric aciduria/succinic semialdehyde dehydrogenase deficiency, hyperinsulinism-hyperammonemia syndrome, and succinic semialdehyde dehydrogenase deficiency.

   

Heptanal

Oenanthic aldehyde

C7H14O (114.1045)


Heptanal, also known as enanthal or N-heptaldehyde, belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Thus, heptanal is considered to be a fatty aldehyde lipid molecule. It is a colourless liquid with a strong fruity odor, which is used as precursor to components in perfumes and lubricants. Heptanal is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Heptanal exists in all eukaryotes, ranging from yeast to humans. Heptanal is an aldehydic, citrus, and fat tasting compound. heptanal is found, on average, in the highest concentration in a few different foods, such as corns, tea, and sweet oranges and in a lower concentration in lemons, wild carrots, and carrots. heptanal has also been detected, but not quantified, in several different foods, such as horned melons, common beets, dills, red bell peppers, and malus (crab apple). This could make heptanal a potential biomarker for the consumption of these foods. The formation of heptanal in the fractional distillation of castor oil was already described in 1878. The large-scale production is based on the pyrolytic cleavage of ricinoleic acid ester (Arkema method) and on the hydroformylation of 1-hexene with rhodium 2-ethylhexanoate as a catalyst upon addition of some 2-ethylhexanoic acid (Oxea method):Heptanal naturally occurs in the essential oils of ylang-ylang (Cananga odorata), clary sage (Salvia sclarea), lemon (Citrus x limon), bitter orange (Citrus x aurantium), rose (Rosa) and hyacinth (Hyacinthus). Heptanal is a potentially toxic compound. Heptanal has been found to be associated with several diseases such as ulcerative colitis, crohns disease, uremia, and nonalcoholic fatty liver disease; also heptanal has been linked to the inborn metabolic disorders including celiac disease. The compound has a flash point of 39.5 °C. The explosion range is between 1.1\\% by volume as the lower explosion limit (LEL) and 5.2\\% by volume as the upper explosion limit. Heptanal or heptanaldehyde is an alkyl aldehyde. Full hydrogenation provides the branched primary alcohol 2-pentylnonan-1-ol, also accessible from the Guerbet reaction from heptanol. A by-product of the given reaction is the unpleasant rancid smelling (Z)-2-pentyl-2-nonenal. Heptanal forms flammable vapor-air mixtures. Heptanal is a flammable, slightly volatile colorless liquid of pervasive fruity to oily-greasy odor, which is miscible with alcohols and practically insoluble in water. Heptanal reacts with benzaldehyde in a Knoevenagel reaction under basic catalysis with high yield and selectivity (> 90\\%) to alpha-pentylcinnamaldehyde (also called jasmine aldehyde because of the typical jasmine odor), which is mostly used in many fragrances as a cis/trans isomer mixture. Found in essential oils of ylang-ylang, clary sage, California orange, bitter orange and others. Flavouring agent

C26H44N7O17P3S (851.1727)


Pentanoyl CoA is an acyl-CoA with the C-5 Acyl chain. Acyl-CoA (or formyl-CoA) is a coenzyme involved in the metabolism of fatty acids. It is a temporary compound formed when coenzyme A (CoA) attaches to the end of a long-chain fatty acid, inside living cells. The CoA is then removed from the chain, carrying two carbons from the chain with it, forming acetyl-CoA. This is then used in the citric acid cycle to start a chain of reactions, eventually forming many adenosine triphosphates. To be oxidatively degraded, a fatty acid must first be activated in a two-step reaction catalyzed by acyl-CoA synthetase. First, the fatty acid displaces the diphosphate group of ATP, then coenzyme A (HSCoA) displaces the AMP group to form an Acyl-CoA. The acyladenylate product of the first step has a large free energy of hydrolysis and conserves the free energy of the cleaved phosphoanhydride bond in ATP. The second step, transfer of the acyl group to CoA (the same molecule that carries acetyl groups as acetyl-CoA), conserves free energy in the formation of a thioester bond. Consequently, the overall reaction Fatty acid + CoA + ATP <=> Acyl-CoA + AMP + PPi has a free energy change near zero. Subsequent hydrolysis of the product PPi (by the enzyme inorganic pyrophosphatase) is highly exergonic, and this reaction makes the formation of acyl-CoA spontaneous and irreversible. Fatty acids are activated in the cytosol, but oxidation occurs in the mitochondria. Because there is no transport protein for CoA adducts, acyl groups must enter the mitochondria via a shuttle system involving the small molecule carnitine. Pentanoyl coA is a acyl-CoA with the C-5 Acyl chain.

Pantetheine 4-phosphate, or 4-phosphopantetheine, is a metabolite in the pantothenate and coenzyme A biosynthesis pathway. It can be generated from Pantatheine (via pantothenate kinase 1) or R-4-Phospho-pantothenoyl-L-cysteine (via phosphopantothenoylcysteine decarboxylase) or Dephospho-CoA (via 4-phosphopantetheine adenylyl-transferase and ectonucleotide pyrophosphatase). In most mammals, coenzyme A can be hydrolyzed to pantetheine and pantothenate in the intestinal lumen via the following series of reactions: coenzyme A leads to phosphopantetheine leads to pantetheine leads to pantothenate. The conversion of 4-phosphopantetheine (4-PP) to dephospho-CoA, is catalyzed by 4-phosphopantetheine adenylyl-transferase. In mammalian systems, this step may occur in the mitochondria or in the cytosol. (PMID: 1746161) It has been identified as an essential cofactor in in the biosynthesis of fatty acids, polyketides, depsipeptides, peptides, and compounds derived from both carboxylic and amino acid precursors. In particular it is a key prosthetic group of acyl carrier protein (ACP) and peptidyl carrier proteins (PCP) and aryl carrier proteins (ArCP) derived from Coenzyme A. Phosphopantetheine fulfils two demands. Firstly, the intermediates remain covalently linked to the synthases (or synthetases) in an energy-rich thiol ester linkage.

Pseudouridine (5-ribosyluracil) is a ubiquitous yet enigmatic constituent of structural RNAs (transfer, ribosomal, small nuclear, and small nucleolar). Although pseudouridine (psi) was the first modified nucleoside to be discovered in RNA, and is the most abundant, its biosynthesis and biological roles have remained poorly understood since its identification as a "fifth nucleoside" in RNA. Recently, a combination of biochemical, biophysical, and genetic approaches has helped to illuminate the structural consequences of psi in polyribonucleotides, the biochemical mechanism of U-->psi isomerization in RNA, and the role of modification enzymes (psi synthases) and box H/ACA snoRNAs, a class of eukaryotic small nucleolar RNAs, in the site-specific biosynthesis of psi. Through its unique ability to coordinate a structural water molecule via its free N1-H, psi exerts a subtle but significant "rigidifying" influence on the nearby sugar-phosphate backbone and also enhances base stacking. These effects may underlie the biological role of most (but perhaps not all) of the psi residues in RNA. Certain genetic mutants lacking specific psi residues in tRNA or rRNA exhibit difficulties in translation, display slow growth rates, and fail to compete effectively with wild-type strains in mixed culture. In particular, normal growth is severely compromised in an Escherichia coli mutant deficient in a pseudouridine synthase responsible for the formation of three closely spaced psi residues in the mRNA decoding region of the 23S rRNA. Such studies demonstrate that pseudouridylation of RNA confers an important selective advantage in a natural biological context. PMID: 10902565 [HMDB].

C20H28N10O19P4 (836.0483)


Diadenosine tetraphosphate (AP4A) is a diadenosine polyphosphate. Diadenosine polyphosphates (APnAs, n=3-6) are a family of endogenous vasoactive purine dinucleotides which have been isolated from thrombocytes. APnAs have been demonstrated to be involved in the control of vascular tone as well as the growth of vascular smooth muscle cells and hence, possibly, in atherogenesis. APnAs isolated substances are Ap3A, Ap4A, Ap5A, and Ap6A. APnAs are naturally occurring substances that facilitate tear secretion; they are released from the corneal epithelium, they stimulate tear production and therefore they may be considered as physiological modulators of tear secretion. The APnAs were discovered in the mid-sixties in the course of studies on aminoacyl-tRNA synthetases (aaRS). APnAs have emerged as intracellular and extracellular signalling molecules implicated in the maintenance and regulation of vital cellular functions and become considered as second messengers. Great variety of physiological and pathological effects in mammalian cells was found to be associated with alterations of APnAs. APnAs are polyphosphated nucleotidic substances which are found in the CNS and are known to be released in a calcium-dependent manner from storage vesicles in brain synaptosomes. AP5A is a specific adenylate kinase inhibitor in the hippocampus, decreasing the rate of decomposition of ADP and the formation of ATP; a pathway that influences the availability of purines in the central nervous system. AP4A is the only APnA that can induce a considerable increase in [Ca2+] in endothelial cells, indicating that its vasoactive effects are comparable to the known effects of arginine vasopressin, Angiotensin II, and ATP. AP4A is a ubiquitous ApnA is a signal molecule for DNA replication in mammalian cells. AP4A is a primer for oligoadenylate synthesis catalyzed by interferon-inducible 2-5A synthetase. AP4A is an avid inhibitor of eosinophil-derived neurotoxin (EDN). EDN is a catalytically proficient member of the pancreatic ribonuclease superfamily secreted along with other eosinophil granule proteins during innate host defense responses and various eosinophil-related inflammatory and allergic diseases. The ribonucleolytic activity of EDN is central to its antiviral and neurotoxic activities and possibly to other facets of its biological activity. (PMID: 11212966, 12738682, 11810214, 9607303, 8922753, 9187362, 16401072, 9694344, 9351706, 1953194). Diadenosine tetraphosphate (AP4A) is a diadenosine polyphosphate. Diadenosine polyphosphates (APnAs, n=3-6) are a family of endogenous vasoactive purine dinucleotides which have been isolated from thrombocytes. APnAs have been demonstrated to be involved in the control of vascular tone as well as the growth of vascular smooth muscle cells and hence, possibly, in atherogenesis. APnAs isolated substances are Ap3A, Ap4A, Ap5A, and Ap6A. APnAs are naturally occurring substances that facilitate tear secretion; they are released from the corneal epithelium, they stimulate tear production and therefore they may be considered as physiological modulators of tear secretion. The APnAs were discovered in the mid-sixties in the course of studies on aminoacyl-tRNA synthetases (aaRS). APnAs have emerged as intracellular and extracellular signalling molecules implicated in the maintenance and regulation of vital cellular functions and become considered as second messengers. Great variety of physiological and pathological effects in mammalian cells was found to be associated with alterations of APnAs. APnAs are polyphosphated nucleotidic substances which are found in the CNS and are known to be released in a calcium-dependent manner from storage vesicles in brain synaptosomes. AP5A is a specific adenylate kinase inhibitor in the hippocampus, decreasing the rate of decomposition of ADP and the formation of ATP; a pathway that influences the availability of purines in the central nervous system.

Carbamic acid

Carbamic acid, potassium salt

CH3NO2 (61.0164)


Carbamic acid is occasionally found as carbamate in workers exposed to pesticides. Carbamates, particularly carbofuran, seem to be more associated with exuberant and diversified symptomatology of pesticide exposure than organophosphates. Neurological symptoms occur among farmers occupationally exposed to acetylcholinesterase-inhibiting insecticides such as carbamates. Carbamic acid products of several amines, such as beta-N-methylamino-L-alanine (BMAA), ethylenediamine, and L-cysteine have been implicated in toxicity. Studies suggested that a significant portion of amino-compounds in biological samples (that naturally contain CO2/bicarbonate) can be present as a carbamic acid. The formation of carbamate glucuronide metabolites has been described for numerous pharmaceuticals and they have been identified in all of the species commonly used in drug metabolism studies (rat, dog, mouse, rabbit, guinea pig, and human). There has been no obvious species specificity for their formation and no preference for 1 or 2 degree amines. Many biological reactions have also been described in the literature that involve the reaction of CO2 with amino groups of biomolecules. For example, CO2 generated from cellular respiration is expired in part through the reversible formation of a carbamate between CO2 and the -amino groups of the alpha and beta-chains of hemoglobin. Glucuronidation is an important mechanism used by mammalian systems to clear and eliminate both endogenous and foreign chemicals. Many functional groups are susceptible to conjugation with glucuronic acid, including hydroxyls, phenols, carboxyls, activated carbons, thiols, amines, and selenium. Primary and secondary amines can also react with carbon dioxide (CO2) via a reversible reaction to form a carbamic acid. The carbamic acid is also a substrate for glucuronidation and results in a stable carbamate glucuronide metabolite. The detection and characterization of these products has been facilitated greatly by the advent of soft ionization mass spectrometry techniques and high field NMR instrumentation.

Phytanate

3,7,11,15-Tetramethylhexadecoanoic acid

C20H40O2 (312.3028)


Phytanic acid (or 3,7,11,15-tetramethylhexadecanoic acid) is a 20-carbon branched-chain fatty acid that humans can obtain through the consumption of dairy products, ruminant animal fats, and certain fish. It is primarily formed by bacterial degradation of chlorophyll in the intestinal tract of ruminants. Unlike most fatty acids, phytanic acid cannot be metabolized by beta-oxidation (because of a methyl group in the beta position). Instead, it undergoes alpha-oxidation in the peroxisome, where it is converted into pristanic acid by the removal of one carbon. Pristanic acid can undergo several rounds of beta-oxidation in the peroxisome to form medium-chain fatty acids that can be converted into carbon dioxide and water in mitochondria. Refsum disease, an autosomal recessive neurological disorder caused by mutations in the PHYH gene, is characterized by having impaired alpha-oxidation activity. Individuals with Refsum disease accumulate large stores of phytanic acid in their blood and tissues. This frequently leads to peripheral polyneuropathy, cerebellar ataxia, retinitis pigmentosa, anosmia, and hearing loss. Therefore, chronically high levels of phytanic acid can be neurotoxic. Phytanic acids neurotoxicity appears to lie in its ability to initiate astrocyte/neural cell death by activating the mitochondrial route of apoptosis. In particular, phytanic acid can induce the substantial generation of reactive oxygen species in isolated mitochondria as well as in intact cells. It also induces the release of cytochrome c from mitochondria. A 20-carbon branched chain fatty acid, Phytanic acid is present in animal (primarily herbivores or omnivores) tissues where it may be derived from the chlorophyll in consumed plant material. Phytanic acid derives from the corresponding alcohol, phytol, and is ultimately oxidized into pristanic acid. In phytanic acid storage disease (Refsum disease) this lipid may comprise as much as 30\\% of the total fatty acids in plasma. These high levels in Refsum disease (a neurological disorder) are due to a phytanic acid alpha-hydroxylase deficiency.; A 20-carbon branched chain fatty acid. In phytanic acid storage disease (Refsum disease) this lipid may comprise as much as 30\\% of the total fatty acids of the plasma. This is due to a phytanic acid alpha-hydroxylase deficiency.

The reactive species in the phosphofructokinase modulation system could be considered thiocysteine (R-S-S-) or cystine trisulfide (R-S-S-S-R) produced from cystine in the presence of gamma-Cystathionase (CST, EC 4.4.1.1). The desulfuration reaction of cystine in vivo produces thiocysteine containing a bound sulfur atom. Persulfide generated from L-cysteine inactivates tyrosine aminotransferase. Thiocysteine is the reactive (unstable) intermediate of thiocystine which functions as a persulfide in transferring its sulfane sulfur to thiophilic acceptors. Thiocystine conversion to unstable thiocysteine is accelerated by sulfhydryl compounds, or reagents that cleave sulfur-sulfur bonds to yield sulfhydryl groups. Thiocystine is proposed as the storage form of sulfane sulfur in biological systems. Liver cytosols contain factors that produce an inhibitor of tyrosine aminotransferase in 3 steps: initial oxidation of cysteine to form cystine; desulfurization of cystine catalyzed by cystathionase to form the persulfide, thiocysteine; and reaction of thiocysteine (or products of its decomposition) with proteins to form protein-bound sulfane.

Phytanoyl CoA is a coenzyme A derivative of phytanic acid. Phytanic acid is present in human diet or in animal tissues where it may be derived from chlorophyll in plant extracts. Specifically it is an epimeric metabolite of the isoprenoid side chain of chlorophyll. Owing to the presence of its epimeric beta-methyl group, phytanic acid cannot be metabolized by beta-oxidation. Instead, it is metabolized in peroxisomes via alpha-oxidation to give pristanic acid, which is then oxidized by beta-oxidation. PhyH (phytanoyl-CoA 2-hydroxylase) catalyses hydroxylation of phytanoyl-CoA. Mutations of PhyH can lead to phytanic acid accumulation. High levels of phytanic acid are found in patients suffering from Refsums syndrome. This inherited neurological disorder is characterized by an accumulation of phytanic acid in blood and tissues. Clinically it is characterized by adult onset retinitis pigmentosa, anosmia, sensory neuropathy, and phytanic acidaemia. This disorder has been found to be related to deficiency in the α-oxidation pathway in the liver. (PMID: 17956235). Phytanoyl CoA and other branched-chain fatty acid CoA products are potent inducers of the peroxisome proliferator-activated receptor PPARalpha, a nuclear receptor that enhances transcription of peroxisomal enzymes mediating beta-oxidation of these potentially toxic fatty acids (PMID: 16768463). Pyruvate dehydrogenase and 2-oxoglutarate dehydrogenase are strongly inhibited by phytanoyl-CoA. Decreased activity of these important mitochondrial metabolism complexes might therefore contribute to neurological symptoms upon accumulation of phytanic acid in Refsum disease (PMID: 16737698).

Hexanal

N-Caproic aldehyde

C6H12O (100.0888)


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.

C35H62N7O17P3S (977.3136)


Tetradecanoyl-CoA (or myristoyl-CoA) is an intermediate in fatty acid biosynthesis, fatty acid elongation and the beta oxidation of fatty acids. It is also used in the myristoylation of proteins. The first pass through the beta-oxidation process starts with the saturated fatty acid palmitoyl-CoA and produces myristoyl-CoA. A total of four enzymatic steps are required, starting with VLCAD CoA dehydrogenase (Very Long Chain) activity, followed by three enzymatic steps catalyzed by enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and ketoacyl-CoA thiolase, all present in the mitochondria. Myristoylation of proteins is also catalyzed by the presence of myristoyl-CoA along with Myristoyl-CoA:protein N-myristoyltransferase (NMT). Myristoylation is an irreversible, co-translational (during translation) protein modification found in animals, plants, fungi and viruses. In this protein modification a myristoyl group (derived from myristioyl CoA) is covalently attached via an amide bond to the alpha-amino group of an N-terminal amino acid of a nascent polypeptide. It is more common on glycine residues but also occurs on other amino acids. Myristoylation also occurs post-translationally, for example when previously internal glycine residues become exposed by caspase cleavage during apoptosis. Myristoylation plays a vital role in membrane targeting and signal transduction in plant responses to environmental stress. Compared to other species that possess a single functional myristoyl-CoA: protein N-myristoyltransferase (NMT) gene copy, human, mouse and cow possess 2 NMT genes, and more than 2 protein isoforms. Myristoyl-coa, also known as S-tetradecanoyl-coenzyme a or myristoyl-coenzyme a, is a member of the class of compounds known as long-chain fatty acyl coas. Long-chain fatty acyl coas are acyl CoAs where the group acylated to the coenzyme A moiety is a long aliphatic chain of 13 to 21 carbon atoms. Myristoyl-coa is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). Myristoyl-coa can be found in a number of food items such as sea-buckthornberry, anise, chicory, and cassava, which makes myristoyl-coa a potential biomarker for the consumption of these food products. Myristoyl-coa can be found primarily in human fibroblasts tissue. Myristoyl-coa exists in all eukaryotes, ranging from yeast to humans. In humans, myristoyl-coa is involved in few metabolic pathways, which include adrenoleukodystrophy, x-linked, beta oxidation of very long chain fatty acids, and fatty acid metabolism. Myristoyl-coa is also involved in several metabolic disorders, some of which include de novo triacylglycerol biosynthesis TG(18:0/14:0/22:0), de novo triacylglycerol biosynthesis tg(i-21:0/12:0/14:0), de novo triacylglycerol biosynthesis TG(18:1(9Z)/14:0/22:2(13Z,16Z)), and de novo triacylglycerol biosynthesis TG(14:0/16:1(9Z)/22:5(4Z,7Z,10Z,13Z,16Z)).

C27H44N7O17P3S (863.1727)


trans-Hexenoyl-CoA is an intermediate in fatty acid metabolism. Beta-oxidation occurs in both mitochondria and peroxisomes. Mitochondria catalyze the beta-oxidation of the bulk of short-, medium-, and long-chain fatty acids derived from diet, and this pathway constitutes the major process by which fatty acids are oxidized to generate energy. Peroxisomes are involved in the beta-oxidation chain shortening of long-chain and very-long-chain fatty acyl-coenzyme (CoAs), long-chain dicarboxylyl-CoAs, the CoA esters of eicosanoids, 2-methyl-branched fatty acyl-CoAs, and the CoA esters of the bile acid intermediates di- and trihydroxycoprostanoic acids, and in the process they generate H2O2. Long-chain and very-long-chain fatty acids (VLCFAs) are also metabolized by the cytochrome P450 CYP4A omega-oxidation system to dicarboxylic acids that serve as substrates for peroxisomal beta-oxidation. The peroxisomal beta-oxidation system consists of (a) a classical peroxisome proliferator-inducible pathway capable of catalyzing straight-chain acyl-CoAs by fatty acyl-CoA oxidase, L-bifunctional protein, and thiolase, and (b) a second noninducible pathway catalyzing the oxidation of 2-methyl-branched fatty acyl-CoAs by branched-chain acyl-CoA oxidase (pristanoyl-CoA oxidase/trihydroxycoprostanoyl-CoA oxidase), D-bifunctional protein, and sterol carrier protein (SCP)x. trans-Hexenoyl-CoA is the substrate of the enzymes enoyl-coenzyme A reductase, acyl-CoA oxidase [EC 1.3.99.2-1.3.3.6], acyl-CoA dehydrogenase, long-chain-acyl-CoA dehydrogenase [EC 1.3.99.3-1.3.99.13], and Oxidoreductases [EC 1.3.99.-]; trans-Hexenoyl-CoA is an intermediate in fatty acid elongation in mitochondria, being the substrate of the enzymes enoyl-CoA hydratase and long-chain-enoyl-CoA hydratase [EC 4.2.1.17-4.2.1.74].

Hydrazine

Hydrazine sulfate (1:1) monosodium salt

H4N2 (32.0374)


Being bifunctional, with two amines, hydrazine is a key building block for the preparation of many heterocyclic compounds via condensation with a range of difunctional electrophiles. With 2,4-pentanedione, it condenses to give the 3,5-dimethylpyrazole. In the Einhorn-Brunner reaction hydrazines react with imides to give triazoles. Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. Thus, it is used as an antioxidant, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems. It is also used to reduce metal salts and oxides to the pure metals in electroless nickel plating and plutonium extraction from nuclear reactor waste. Hydrazine is an inorganic chemical compound with the formula N2H4. It is a colourless liquid with an ammonia-like odor and is derived from the same industrial chemistry processes that manufacture ammonia. However, hydrazine has physical properties that are more similar to those of water. The propanone azine is an intermediate in the Atofina-PCUK synthesis. Direct alkylation of hydrazines with alkyl halides in the presence of base affords alkyl-substituted hydrazines, but the reaction is typically inefficient due to poor control on level of substitution (same as in ordinary amines). The reduction of hydrazones to hydrazines present a clean way to produce 1,1-dialkylated hydrazines.

Diadenosine triphosphate (AP3A) is a diadenosine polyphosphate. Diadenosine polyphosphates (APnAs, n = 3-6) are a family of endogenous vasoactive purine dinucleotides which have been isolated from thrombocytes. APnAs have been demonstrated to be involved in the control of vascular tone as well as the growth of vascular smooth muscle cells and hence, possibly, in atherogenesis. APnAs isolated substances are Ap3A, Ap4A, Ap5A, and Ap6A. APnAs are naturally occurring substances that facilitate tear secretion; they are released from the corneal epithelium, they stimulate tear production and therefore they may be considered as physiological modulators of tear secretion. The APnAs were discovered in the mid-sixties in the course of studies on aminoacyl-tRNA synthetases (aaRS). APnAs have emerged as intracellular and extracellular signalling molecules implicated in the maintenance and regulation of vital cellular functions and become considered as second messengers. Great variety of physiological and pathological effects in mammalian cells was found to be associated with alterations of APnAs. APnAs are polyphosphated nucleotidic substances which are found in the CNS and are known to be released in a calcium-dependent manner from storage vesicles in brain synaptosomes. AP3A is a primer for oligoadenylate synthesis catalyzed by interferon-inducible 2-5A synthetase. AP3A is synthesized in cells by tryptophanyl-tRNA synthetase (WRS); cellular level of AP3A significantly increases after interferon treatment. AP3A is an avid inhibitor of eosinophil-derived neurotoxin (EDN). EDN is a catalytically proficient member of the pancreatic ribonuclease superfamily secreted along with other eosinophil granule proteins during innate host defense responses and various eosinophil-related inflammatory and allergic diseases. The ribonucleolytic activity of EDN is central to its antiviral and neurotoxic activities and possibly to other facets of its biological activity. AP3A accumulates in cells in response to various physiological factors. AP3A FHIT (Fragile histidine Triad) is a human tumor suppressor gene. The Fhit protein is believed to inhibit tumor growth by inducing apoptosis through interaction with AP3A.

Methylarsonate is used as a contact herbicide in either the monosodium or disodium salt form. It goes by the trade names Weed-E-Rad, Ansar 170 H.C., Ansar 529 H.C., DiTac and others. Methylarsonate is considered only slightly toxic, having an oral LD50 of 2200 mg/Kg for rats. The inhalation risk is greater with LD50 Rats >20 mg. Long term studies with people exposed to organoarsenicals has shown an increased risk of skin cancer (Spiewak, 2001), lung cancer and some liver cancers, although some recent studies have shown some arsenic containing compounds (specifically Arsine trioxide) may have anticarcinogenic properties (Wang, 2001). In mammals, Methylarsonate is also an intermediate in the detoxification of inorganic arsenic. In the arsenate detoxification I pathway, arsenite reacts with S-adenosyl-L-methionine to produce methylarsonate and S-adenosyl-L-homocysteine. Arsenite methyltransferase catalyzes this reaction. Methylarsonate then reacts with 2 glutathione molecules to produce glutathione disulfide and methylarsonite. This reaction is catalyzed by methylarsonate reductase. Methylarsonate is an organic arsenic compound with adverse effects similar to those of arsenic trioxide. Arsenic is found in the environment primarily as arsenate and arsenite species. Arsenate is reduced to arsenite by arsenate reductase and can be subsequently methylated to Methylarsonate. This is then reduced and methylated to Dimethylarsinate, which can excreted and is considerably less toxic to the organism than any of the previous intermediate compounds. Methylarsonate was formerly included in some vitamin and mineral preparations. It was once used to treat tuberculosis, chorea, and other affections in which the cacodylates were used.

Isopentyl acetate

Acetic acid, 3-methylbutyl ester

C7H14O2 (130.0994)


Isopentyl acetate, also known as isoamyl acetate or amylacetic ester, belongs to the class of organic compounds known as carboxylic acid esters. These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). Isopentyl acetate is an ester formed from isoamyl alcohol and acetic acid. It is a colorless liquid that is only slightly soluble in water, but very soluble in most organic solvents. Isopentyl acetate has a sweet, fruity banana odor and similar sweet, fruity banana taste. Isopentyl acetate is used to confer banana flavor in foods. Isopentyl acetate is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Outside of the human body, Isopentyl acetate is found, on average, in the highest concentration within a few different foods, such as red wines, white wines, and beers. Isopentyl acetate has also been detected, but not quantified in, several different foods, such as blackberries (Rubus), figs (Ficus carica), red teas, bananas (Musa acuminata), and black elderberries (Sambucus nigra). This could make isopentyl acetate a potential biomarker for the consumption of these foods. Isopentyl acetate occurs naturally in the banana plant and it is also produced synthetically. Based on a literature review a significant number of articles have been published on Isopentyl acetate. Pure isopentyl acetate, or mixtures of isopentyl acetate, amyl acetate, and other flavors may be referred to as banana oil. Because of its intense, pleasant odor and its low toxicity, isopentyl acetate is used to test the effectiveness of respirators or gas masks. Isopentyl acetate is released by a honey bees sting where it serves as a pheromone beacon to attract other bees and provoke them to sting. Present in many fruit aromas, especies banana. It is used in banana flavouring

C5H7NO2 (113.0477)


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

Hippuric acid

Phenylcarbonylaminoacetic acid

C9H9NO3 (179.0582)


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.

A smaller fraction of the absorbed toluene is oxidized into aromatic compounds including ortho-cresol, which is not found in the urine of nonexposed individuals in a significant amount. 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 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. Hippuric acid is an endogenous phenolic acid metabolite detected after the consumption of whole grain.

acetoacetic acid

3-Oxobutanoic acid, 9CI

C4H6O3 (102.0317)


A 3-oxo monocarboxylic acid that is butyric acid bearing a 3-oxo substituent. It is a weak organic acid and can be produced in the human liver under certain conditions of poor metabolism leading to excessive fatty acid breakdown (diabetes mellitus leading to diabetic ketoacidosis), it is then partially converted to acetone by decarboxylation and excreted either in urine or through respiration. Persistent mild hyperketonemia is a common finding in newborns. These compounds serve as an indispensable source of energy for extrahepatic tissues, especially the brain and lung of developing rats. Another important function of ketone bodies is to provide acetoacetyl-CoA and acetyl-CoA for synthesis of cholesterol, fatty acids, and complex lipids. During the early postnatal period, acetoacetate (AcAc) and beta-hydroxybutyrate are preferred over glucose as substrates for synthesis of phospholipids and sphingolipids in accord with requirements for brain growth and myelination. Thus, during the first 2 wk of postnatal development, when the accumulation of cholesterol and phospholipids accelerates, the proportion of ketone bodies incorporated into these lipids increases. On the other hand, an increased proportion of ketone bodies are utilized for cerebroside synthesis during the period of active myelination. In the lung, AcAc serves better than glucose as a precursor for the synthesis of lung phospholipids. The synthesized lipids, particularly dipalmityl phosphatidylcholine, are incorporated into surfactant, and thus have a potential role in supplying adequate surfactant lipids to maintain lung function during the early days of life. (PMID 3884391) The acid is also present in the metabolism of those undergoing starvation or prolonged physical exertion as part of gluconeogenesis. When ketone bodies are measured by way of urine concentration, acetoacetic acid, along with beta-hydroxybutyric acid or acetone, is what is detected. [HMDB]

C26H44N7O17P3S (851.1727)


Pentanoyl CoA is an acyl-CoA with the C-5 Acyl chain. Acyl-CoA (or formyl-CoA) is a coenzyme involved in the metabolism of fatty acids. It is a temporary compound formed when coenzyme A (CoA) attaches to the end of a long-chain fatty acid, inside living cells. The CoA is then removed from the chain, carrying two carbons from the chain with it, forming acetyl-CoA. This is then used in the citric acid cycle to start a chain of reactions, eventually forming many adenosine triphosphates. To be oxidatively degraded, a fatty acid must first be activated in a two-step reaction catalyzed by acyl-CoA synthetase. First, the fatty acid displaces the diphosphate group of ATP, then coenzyme A (HSCoA) displaces the AMP group to form an Acyl-CoA. The acyladenylate product of the first step has a large free energy of hydrolysis and conserves the free energy of the cleaved phosphoanhydride bond in ATP. The second step, transfer of the acyl group to CoA (the same molecule that carries acetyl groups as acetyl-CoA), conserves free energy in the formation of a thioester bond. Consequently, the overall reaction Fatty acid + CoA + ATP <=> Acyl-CoA + AMP + PPi has a free energy change near zero. Subsequent hydrolysis of the product PPi (by the enzyme inorganic pyrophosphatase) is highly exergonic, and this reaction makes the formation of acyl-CoA spontaneous and irreversible. Fatty acids are activated in the cytosol, but oxidation occurs in the mitochondria. Because there is no transport protein for CoA adducts, acyl groups must enter the mitochondria via a shuttle system involving the small molecule carnitine.

Sugar phosphate, also known as sinapoylcholine or sinapine, belongs to coumaric acids and derivatives class of compounds. Those are aromatic compounds containing Aromatic compounds containing a cinnamic acid moiety (or a derivative thereof) hydroxylated at the C2 (ortho-), C3 (meta-), or C4 (para-) carbon atom of the benzene ring. Sugar phosphate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Sugar phosphate can be found in a number of food items such as common sage, tea leaf willow, broccoli, and sweet bay, which makes sugar phosphate a potential biomarker for the consumption of these food products. Sugar phosphate exists in all living organisms, ranging from bacteria to humans. Sinapine (CAS: 18696-26-9), also known as sinapoylcholine, belongs to the class of organic compounds known as morphinans. These are polycyclic compounds with a four-ring skeleton with three condensed six-member rings forming a partially hydrogenated phenanthrene moiety, one of which is aromatic while the two others are alicyclic. Sinapine is an extremely weak basic (essentially neutral) compound (based on its pKa). Sinapine has been detected, but not quantified, in garden cress and horseradish. Sinapine is found in brassicas. It is a storage protein isolated from the seeds of Brassica napus (rape). This could make sinapine a potential biomarker for the consumption of these foods. Sinapine is an acylcholine in which the acyl group specified is sinapoyl. It has a role as a photosynthetic electron-transport chain inhibitor, an antioxidant and a plant metabolite. It is functionally related to a trans-sinapic acid. Sinapine is a natural product found in Alliaria petiolata, Isatis quadrialata, and other organisms with data available. An acylcholine in which the acyl group specified is sinapoyl. Sinapine is an alkaloid isolated from seeds of the cruciferous species. Sinapine exhibits anti-inflammatory, anti-oxidant, anti-tumor, anti-angiogenic and radio-protective effects. Sinapine is also an acetylcholinesterase (AChE) inhibitor and can be used for the research of Alzheimer’s disease, ataxia, myasthenia gravis, and Parkinson’s disease[1][2][3][4].

Target: α2-adrenergic receptor Tizanidine is a drug that is used as a muscle relaxant. It is a centrally acting α2 adrenergic agonist. It is used to treat the spasms, cramping, and tightness of muscles caused by medical problems such as multiple sclerosis, ALS, spastic diplegia, back pain, or certain other injuries to the spine or central nervous system. It is also prescribed off-label for migraine headaches, as a sleep aid, and as an anticonvulsant. It is also prescribed for some symptoms of fibromyalgia. Tizanidine has been found to be as effective as other antispasmodic drugs and has superior tolerability to that of baclofen and diazepam. Tizanidine can be very strong even at the 2 mg dose and may cause hypotension, so caution is advised when it is used in patients who have a history of orthostatic hypotension, or when switching from gel cap to tablet form and vice versa. Tizanidine can occasionally cause liver damage, generally the hepatocellular type. Clinical trials show that up to 5\% of patients treated with tizanidine had elevated liver function test values, though symptoms disappeared upon withdrawal of the drug. Care should be used when first beginning treatment with tizanidine with regular liver tests for the first 6 months of treatment.
