Epicatechin

C15H14O6 (290.079)

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

L-Valine

C5H11NO2 (117.079)

L-valine is the L-enantiomer of valine. It has a role as a nutraceutical, a micronutrient, a human metabolite, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a pyruvate family amino acid, a proteinogenic amino acid, a valine and a L-alpha-amino acid. It is a conjugate base of a L-valinium. It is a conjugate acid of a L-valinate. It is an enantiomer of a D-valine. It is a tautomer of a L-valine zwitterion. Valine is a branched-chain essential amino acid that has stimulant activity. It promotes muscle growth and tissue repair. It is a precursor in the penicillin biosynthetic pathway. L-Valine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Valine is an aliphatic and extremely hydrophobic essential amino acid in humans related to leucine, Valine is found in many proteins, mostly in the interior of globular proteins helping to determine three-dimensional structure. A glycogenic amino acid, valine maintains mental vigor, muscle coordination, and emotional calm. Valine is obtained from soy, cheese, fish, meats and vegetables. Valine supplements are used for muscle growth, tissue repair, and energy. (NCI04) Valine (abbreviated as Val or V) is an -amino acid with the chemical formula HO2CCH(NH2)CH(CH3)2. It is named after the plant valerian. L-Valine is one of 20 proteinogenic amino acids. Its codons are GUU, GUC, GUA, and GUG. This essential amino acid is classified as nonpolar. Along with leucine and isoleucine, valine is a branched-chain amino acid. Branched chain amino acids (BCAA) are essential amino acids whose carbon structure is marked by a branch point. These three amino acids are critical to human life and are particularly involved in stress, energy and muscle metabolism. BCAA supplementation as therapy, both oral and intravenous, in human health and disease holds great promise. BCAA denotes valine, isoleucine and leucine which are branched chain essential amino acids. Despite their structural similarities, the branched amino acids have different metabolic routes, with valine going solely to carbohydrates, leucine solely to fats and isoleucine to both. The different metabolism accounts for different requirements for these essential amino acids in humans: 12 mg/kg, 14 mg/kg and 16 mg/kg of valine, leucine and isoleucine respectively. Furthermore, these amino acids have different deficiency symptoms. Valine deficiency is marked by neurological defects in the brain, while isoleucine deficiency is marked by muscle tremors. Many types of inborn errors of BCAA metabolism exist, and are marked by various abnormalities. The most common form is the maple syrup urine disease, marked by a characteristic urinary odor. Other abnormalities are associated with a wide range of symptoms, such as mental retardation, ataxia, hypoglycemia, spinal muscle atrophy, rash, vomiting and excessive muscle movement. Most forms of BCAA metabolism errors are corrected by dietary restriction of BCAA and at least one form is correctable by supplementation with 10 mg of biotin daily. BCAA are decreased in patients with liver disease, such as hepatitis, hepatic coma, cirrhosis, extrahepatic biliary atresia or portacaval shunt; aromatic amino acids (AAA) tyrosine, tryptophan and phenylalanine, as well as methionine are increased in these conditions. Valine in particular, has been established as a useful supplemental therapy to the ailing liver. All the BCAA probably compete with AAA for absorption into the brain. Supplemental BCAA with vitamin B6 and zinc help normalize the BCAA:AAA ratio. In sickle-cell disease, valine substitutes for the hydrophilic amino acid glutamic acid in hemoglobin. Because valine is hydrophobic, the hemoglobin does not fold correctly. Valine is an essential amino acid, hence it must be ingested, usually as a component of proteins. A branched-chain essential amino acid that has stimulant activity. It promotes muscle growth and ... Valine (Val) or L-valine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (‚ÄìNH2) and carboxyl (‚ÄìCOOH) functional groups, along with a side chain (R group) specific to each amino acid. L-valine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Valine is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aliphatic amino acid. Valine was first isolated from casein in 1901 by Hermann Emil Fischer. The name valine comes from valeric acid, which in turn is named after the plant valerian due to the presence of valine in the roots of the plant. Valine is essential in humans, meaning the body cannot synthesize it, and it must be obtained from the diet. Human dietary sources are foods that contain protein, such as meats, dairy products, soy products, beans and legumes. L-valine is a branched chain amino acid (BCAA). The BCAAs consist of leucine, valine and isoleucine (and occasionally threonine). BCAAs are essential amino acids whose carbon structure is marked by a branch point at the beta-carbon position. BCAAs are critical to human life and are particularly involved in stress, energy and muscle metabolism. BCAA supplementation as therapy, both oral and intravenous, in human health and disease holds great promise. BCAAs have different metabolic routes, with valine going solely to carbohydrates (glucogenic), leucine solely to fats (ketogenic) and isoleucine being both a glucogenic and a ketogenic amino acid. The different metabolism accounts for different requirements for these essential amino acids in humans: 12 mg/kg, 14 mg/kg and 16 mg/kg of valine, leucine and isoleucine respectively. Like other branched-chain amino acids, the catabolism of valine starts with the removal of the amino group by transamination, giving alpha-ketoisovalerate, an alpha-keto acid, which is converted to isobutyryl-CoA through oxidative decarboxylation by the branched-chain Œ±-ketoacid dehydrogenase complex. This is further oxidised and rearranged to succinyl-CoA, which can enter the citric acid cycle. Furthermore, these amino acids have different deficiency symptoms. Valine deficiency is marked by neurological defects in the brain, while isoleucine deficiency is marked by muscle tremors. Many types of inborn errors of BCAA metabolism exist, and are marked by various abnormalities. The most common form is the maple syrup urine disease, marked by a characteristic urinary odor. Other abnormalities are associated with a wide range of symptoms, such as mental retardation, ataxia, hypoglycemia, spinal muscle atrophy, rash, vomiting and excessive muscle movement. Most forms of BCAA metabolism errors are corrected by dietary restriction of BCAA and at least one form is correctable by supplementation with 10 mg of biotin daily. BCAA are decreased in patients with liver disease, such as hepatitis, hepatic coma, cirrhosis, extrahepatic biliary atresia or portacaval shunt. Valine in particular, has been established as a useful supplemental therapy to the ailing liver. Valine, like other branched-chain amino acids, is associated with insulin resistance: higher levels of valine are observed in the blood of diabetic mice, rats, and humans (PMID: 25287287). Mice fed a valine deprivation diet for one day have improved insulin sensitivity and feeding of a valine deprivation diet for one week significantly decreases blood glucose levels (PMID: 24684822). In diet-induced obese and insulin resistant mice, a diet with decreased levels of valine and the other branched-chain amino acids results in reduced adiposity and improved insulin sensitivity (PMID: 29266268). In sickle-cell disease, valine substitutes for the hydrophilic amino acid glutamic acid in hemoglobin. Because valine ... L-valine, also known as (2s)-2-amino-3-methylbutanoic acid or L-(+)-alpha-aminoisovaleric acid, belongs to valine and derivatives class of compounds. Those are compounds containing valine or a derivative thereof resulting from reaction of valine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. L-valine is soluble (in water) and a moderately acidic compound (based on its pKa). L-valine can be found in watermelon, which makes L-valine a potential biomarker for the consumption of this food product. L-valine can be found primarily in most biofluids, including cerebrospinal fluid (CSF), breast milk, urine, and blood, as well as in human epidermis and fibroblasts tissues. L-valine exists in all living species, ranging from bacteria to humans. In humans, L-valine is involved in several metabolic pathways, some of which include streptomycin action pathway, tetracycline action pathway, methacycline action pathway, and kanamycin action pathway. L-valine is also involved in several metabolic disorders, some of which include methylmalonic aciduria due to cobalamin-related disorders, 3-methylglutaconic aciduria type III, isovaleric aciduria, and methylmalonic aciduria. Moreover, L-valine is found to be associated with schizophrenia, alzheimers disease, paraquat poisoning, and hypervalinemia. L-valine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Valine (abbreviated as Val or V) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH3+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain isopropyl group, making it a non-polar aliphatic amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet. Human dietary sources are foods that contain protein, such as meats, dairy products, soy products, beans and legumes. In the genetic code it is encoded by all codons starting with GU, namely GUU, GUC, GUA, and GUG (Applies to Valine, Leucine and Isoleucine)
This group of essential amino acids are identified as the branched-chain amino acids, BCAAs. Because this arrangement of carbon atoms cannot be made by humans, these amino acids are an essential element in the diet. The catabolism of all three compounds initiates in muscle and yields NADH and FADH2 which can be utilized for ATP generation. The catabolism of all three of these amino acids uses the same enzymes in the first two steps. The first step in each case is a transamination using a single BCAA aminotransferase, with a-ketoglutarate as amine acceptor. As a result, three different a-keto acids are produced and are oxidized using a common branched-chain a-keto acid dehydrogenase, yielding the three different CoA derivatives. Subsequently the metabolic pathways diverge, producing many intermediates.
The principal product from valine is propionylCoA, the glucogenic precursor of succinyl-CoA. Isoleucine catabolism terminates with production of acetylCoA and propionylCoA; thus isoleucine is both glucogenic and ketogenic. Leucine gives rise to acetylCoA and acetoacetylCoA, and is thus classified as strictly ketogenic.
There are a number of genetic diseases associated with faulty catabolism of the BCAAs. The most common defect is in the branched-chain a-keto acid dehydrogenase. Since there is only one dehydrogenase enzyme for all three amino acids, all three a-keto acids accumulate and are excreted in the urine. The disease is known as Maple syrup urine disease because of the characteristic odor of the urine in afflicted individuals. Mental retardation in these cases is extensive. Unfortunately, since these are essential amino acids, they cannot be heavily restricted in the diet; ultimately, the life of afflicted individuals is short and development is abnormal The main neurological pr...

Fumaric acid

C4H4O4 (116.011)

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

Isofucosterol

C29H48O (412.3705)

Isofucosterol, also known as delta5-avenasterol, is a phytosterol. Phytosterols, or plant sterols, are compounds that occur naturally and bear a close structural resemblance to cholesterol but have different side-chain configurations. Phytosterols are relevant in pharmaceuticals (production of therapeutic steroids), nutrition (anti-cholesterol additives in functional foods, anti-cancer properties), and cosmetics (creams, lipstick). Phytosterols can be obtained from vegetable oils or from industrial wastes, which gives an added value to the latter. Considerable efforts have been recently dedicated to the development of efficient processes for phytosterol isolation from natural sources. The present work aims to summarize information on the applications of phytosterols and to review recent approaches, mainly from the industry, for the large-scale recovery of phytosterols (PMID: 17123816, 16481154). Isofucosterol is found to be associated with phytosterolemia, which is an inborn error of metabolism. Isofucosterol, also known as (24z)-stigmasta-5,24(28)-dien-3-ol or delta5-avenasterol, belongs to stigmastanes and derivatives class of compounds. Those are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. Thus, isofucosterol is considered to be a sterol lipid molecule. Isofucosterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Isofucosterol can be found in a number of food items such as globe artichoke, gooseberry, deerberry, and ucuhuba, which makes isofucosterol a potential biomarker for the consumption of these food products. Isofucosterol can be found primarily in blood. Moreover, isofucosterol is found to be associated with sitosterolemia. Isofucosterol is a 3beta-sterol consisting of stigmastan-3beta-ol with double bonds at positions 5 and 24(28). The double bond at postion 24(28) adopts a Z-configuration. It has a role as an animal metabolite, a plant metabolite, an algal metabolite and a marine metabolite. It is a 3beta-sterol, a 3beta-hydroxy-Delta(5)-steroid, a C29-steroid and a member of phytosterols. It derives from a hydride of a stigmastane. Fucosterol is a natural product found in Echinometra lucunter, Ulva fasciata, and other organisms with data available. A 3beta-sterol consisting of stigmastan-3beta-ol with double bonds at positions 5 and 24(28). The double bond at postion 24(28) adopts a Z-configuration. Fucosterol is a sterol isolated from algae, seaweed or diatoms.?Fucosterol exhibits various biological activities, including antioxidant, anti-adipogenic, blood cholesterol reducing, anti-diabetic and anti-cancer activities[1][2].

5-Hydroxymethyluracil

C5H6N2O3 (142.0378)

5-Hydroxymethyluracil (5hmU), also known as alpha-hydroxythymine, 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. 5hmU has been identified as a thymine base modification found in the genomes of a diverse range of organisms (PMID: 28137275). 5-hydroxymethyluracil has been detected in bacteriophages, dinoflagellates, leishmania, and in eukaryotic genomes where its level appears to be cell type-specific. 5-Hydroxymethyluracil arises from the oxidation of thymine. 5-Hydroxymethyluracil is produced by the enzyme thymine dioxygenase (EC 1.14.11.6) which catalyzes the chemical reaction thymine + 2-oxoglutarate + O2 <-> 5-hydroxymethyluracil + succinate + CO2. The 3 substrates of this enzyme are thymine, 2-oxoglutarate, and O2, whereas its 3 products are 5-hydroxymethyluracil, succinate, and CO2. The 5hmU base can also be generated by oxidation/hydroxylation of thymine by the Ten-Eleven-Translocation (TET) proteins or result from deamination of 5hmC (PMID: 29184924). DNA containing 5hmU has been reported to be more flexible and hydrophilic (PMID: 29184924). 5-Hydroxymethyluracil is an oxidation damage product derived from thymine or 5-methylcytosine. It is a product of thymine dioxygenase [EC 1.14.11.6].

Oxoglutaric acid

C5H6O5 (146.0215)

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

6-Methyladenine

C6H7N5 (149.0701)

6-Methyladenine is a methylated adenine residue. The formation of internal 6-methyladenine (m6A) residues in eucaryotic messenger RNA (mRNA) is a postsynthetic modification in which S-adenosyl-L-methionine (SAM) serves as the methyl donor. 6-Methyladenine residues have also been localized to heterogeneous nuclear RNA (HnRNA), and for the most part these residues are conserved during mRNA processing. Although the biological significance of internal adenine methylation in eucaryotic mRNA remains unclear, a great deal of research has indicated that this modification may be required for mRNA transport to the cytoplasm, the selection of splice sites or other RNA processing reactions. The presence of m6A residues increases the in vitro translation efficiency of dihydrofolate reductase; an inhibition of m6A residues in dihydrofolate reductase transcripts significantly alters their rate of translation. m6A is found in many human fluids: oviductal fluid, blood plasma and urine.

Pipecolic acid

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.

C14H11Cl2NO2 (295.0167)

Meclofenamic acid is only found in individuals that have used or taken this drug. It is a non-steroidal anti-inflammatory agent with antipyretic and antigranulation activities. It also inhibits prostaglandin biosynthesis. [PubChem]The mode of action, like that of other nonsteroidal anti-inflammatory agents, is not known. Therapeutic action does not result from pituitary-adrenal stimulation. In animal studies, meclofenamic acid was found to inhibit prostaglandin synthesis and to compete for binding at the prostaglandin receptor site. In vitro meclofenamic acid was found to be an inhibitor of human leukocyte 5-lipoxygenase activity. These properties may be responsible for the anti-inflammatory action of meclofenamic acid. There is no evidence that meclofenamic acid alters the course of the underlying disease.

1-Methyladenosine

C11H15N5O4 (281.1124)

1-Methyladenosine, also known as M1A, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Precise m6A mapping by m6A-CLIP/IP (briefly m6A-CLIP) revealed that a majority of m6A locates in the last exon of mRNAs in multiple tissues/cultured cells of mouse and human, and the m6A enrichment around stop codons is a coincidence that many stop codons locate round the start of last exons where m6A is truly enriched. The methylation of adenosine is directed by a large m6A methyltransferase complex containing METTL3 as the SAM-binding sub-unit. Insulin-like growth factor-2 mRNA-binding proteins 1, 2, and 3 (IGF2BP1-3) are reported as a novel class of m6A readers. 1-Methyladenosine is an RNA modification originating essentially from two different reaction types, one catalyzed by enzymes and the other the result of the reaction of RNA with certain alkylating agents. 1-Methyladenosine is an RNA modification originating essentially from two different reaction types, one catalyzed by enzymes and the other the result of the reaction of RNA with certain alkylating agents.

Isocitric acid

C6H8O7 (192.027)

Isocitric acid, also known as isocitrate belongs to the class of organic compounds known as tricarboxylic acids and derivatives. These are carboxylic acids containing exactly three carboxyl groups. Isocitric acid is a TCA (tricarboxylic acid) cycle intermediate. It is a structural isomer of citric acid and is formed from citrate with the help of the enzyme aconitase. More specifically, Isocitric acid is synthesized from citric acid via the intermediate cis-aconitic acid by the enzyme aconitase (aconitate hydratase). Isocitrate is acted upon by isocitrate dehydrogenase (IDH) to form alpha-ketoglutarate. This is a two-step process, which involves oxidation of isocitrate to oxalosuccinate (a ketone), followed by the decarboxylation of the carboxyl group beta to the ketone, forming alpha-ketoglutarate. In humans, IDH exists in three isoforms: IDH3 catalyzes the third step of the citric acid cycle while converting NAD+ to NADH in the mitochondria. The isoforms IDH1 and IDH2 catalyze the same reaction outside the context of the citric acid cycle and use NADP+ as a cofactor instead of NAD+. They localize to the cytosol as well as the mitochondrion and peroxisome. Isocitric acid exists in all living species, ranging from bacteria to plants to humans. Isocitric acid is a minor organic acid found in most fruit juices, especially in blackberries, youngberries, and boyberries, and in vegetables, especially in carrots. The determination of D-isocitric acid has become of importance in the analysis of fruit juices for the detection of illegal additives (adulteration). Since the quantities of citric and isocitric acids are correlated in fruit juices, a high ratio of citric to isocitric acid can indicate the addition of citric acid as an alduterant. In authentic orange juice, for example, the ratio of citric acid to D-isocitric acid is usually less than 130. Isocitric acid is mostly used in the food industry (food additive) as a food acidulant. The citrate oxidation to isocitrate is catalyzed by the enzyme aconitase. Human prostatic secretion is remarkably rich in citric acid and low aconitase activity will therefore play a significant role in enabling accumulation of high citrate levels (PubMed ID 8115279) [HMDB]. Isocitric acid is found in many foods, some of which are wild carrot, redcurrant, carrot, and soursop. [Spectral] Isocitrate (exact mass = 192.027) and CDP (exact mass = 403.01818) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX.

Glucosamine 6-phosphate

C6H14NO8P (259.0457)

Glucosamine 6-phosphate (CAS: 3616-42-0) is normally produced in endothelial cells via de novo glucosamine synthesis by the enzyme fructose-6-phosphate amidotransferase and the modulation of this pathway by hyperglycemia and glutamine.

D-2-Hydroxyglutaric acid

C5H8O5 (148.0372)

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

N,N-Dimethylformamide

C3H7NO (73.0528)

Dimethylformamide is a polar (hydrophilic) Aprotic solvent with a high boiling point. It facilitates reactions that follow polar mechanisms, such as SN2 reactions. Dimethylformamide can be synthesized from methyl formate and dimethyl amine or reaction of dimethyl amine and carbon monoxide. Dimethylformamide is not stable in the presence of strong bases like sodium hydroxide or strong acids such as hydrochloric acid or sulfuric acid and is hydrolyzed back into formic acid and dimethylamine, especially at elevated temperatures.; Dimethylformamide is the organic compound with the formula (CH3)2NC(O)H. Commonly abbreviated DMF (though this acronym is sometimes used for dimethylfuran), this colourless liquid is miscible with water and the majority of organic liquids. DMF is a common solvent for chemical reactions. Pure dimethylformamide is odorless whereas technical grade or degraded dimethylformamide often has a fishy smell due to impurity of dimethylamine. Its name is derived from the fact that it is a derivative of formamide, the amide of formic acid.; N,N-Dimethylformamide (DMF) is a clear liquid that has been widely used in industries as a solvent, an additive, or an intermediate because of its extensive miscibility with water and most common organic solvents. Its health effects include hepatotoxicity and male reproductoxicity, possibly linked with mitochondrial DNA (mtDNA) alterations including mtDNA common deletion (delta-mtDNA4977) and mtDNA copy number; during the biotransformation of DMF in the body, free radicals are formed, including hydroxyl radicals.; The world-wide consumption of DMF in 2001 was approximately 285,000 metric tonnes and most of that was used as an industrial solvent. Overexposure to DMF could result in hepatotoxicity, alcohol intolerance, possible embryotoxicity and teratogenicity in humans and animals, and decline of human sperm motility. Based on its wide application and a wide range of toxic effects, DMF has been selected as one of the four priority compounds for human field studies by the National Toxicology Program (NTP) of the US National Institute of Environmental Health Sciences (NIEHS). The current permissible exposure limit for DMF in the working environment is 10 ppm in both USA and Taiwan. The concentrations of two major DMF metabolites in urine, N-methylformamide (U-NMF) of 15 mg/L and N-acetyl-S-(N-methylcarbamoyl) cysteine (U-AMCC) of 40 mg/L, were recommended as the biological exposure indices (BEIs) by the American Conference of Governmental Industrial Hygienists for DMF exposure in workplace.

Hydrogen

H2 (2.0156)

Hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2. With an atomic weight of 1.00794, hydrogen is the lightest element. Besides the common H1 isotope, hydrogen exists as the stable isotope Deuterium and the unstable, radioactive isotope Tritium. Hydrogen is the most abundant of the chemical elements, constituting roughly 75\\% of the universes elemental mass. Hydrogen can form compounds with most elements and is present in water and most organic compounds. It plays a particularly important role in acid-base chemistry, in which many reactions involve the exchange of protons between soluble molecules. Oxidation of hydrogen, in the sense of removing its electron, formally gives H+, containing no electrons and a nucleus which is usually composed of one proton. That is why H+ is often called a proton. This species is central to discussion of acids. Under the Bronsted-Lowry theory, acids are proton donors, while bases are proton acceptors. A bare proton H+ cannot exist in solution because of its strong tendency to attach itself to atoms or molecules with electrons. However, the term proton is used loosely to refer to positively charged or cationic hydrogen, denoted H+. H2 is a product of some types of anaerobic metabolism and is produced by several microorganisms, usually via reactions catalyzed by iron- or nickel-containing enzymes called hydrogenases. These enzymes catalyze the reversible redox reaction between H2 and its component two protons and two electrons. Creation of hydrogen gas occurs in the transfer of reducing equivalents produced during pyruvate fermentation to water. Hydrogen has been found to be a metabolite of Citrobacter, Cyanobacteria, Enterobacter, Halobacterium and Rhodobacteraceae (PMID: 28042989; PMID: 16371161) (https://www.insa.nic.in/writereaddata/UpLoadedFiles/PINSA/Vol51B_1985_2_Art16.pdf) (https://www.researchgate.net/publication/222428793_High_Hydrogen_Yield_from_a_Two-step_Process_of_Dark-_and_Photo-fermentation_of_Sucrose) (Tao, Y; Chen, Y; Wu, Y; He, Y; Zhou, Z (2007).

Tungsten

W (183.951)

Tungsten is a transition metal found, along with chromium, molybdenum and seaborgium, in Group VI of the Periodic Table of elements. Since its discovery in the last quarter of 18th century, tungsten-based products have been in use in a wide range of applications stretching from daily household necessities to highly specialized components of modern science and technology. As new applications and uses are discovered continuously, interest on and demand for tungsten, already an essential commodity, are projected to increase steadily in the years to come. Unavoidably, as is the case with other natural materials and/or non-renewable resources, increased demand and use of tungsten will spawn (a) increased interactions with other materials and/or non-sustainable practices, (b) a greater number of possible entry points into the natural and human environment and (c) a higher probability of deliberate or accidental releases. Currently, the existing knowledge base does not provide clear information about the behavior of tungsten-based products in the environment. The toxicological profile of tungsten, including possible effects on living organisms and exposure pathways, remains rather sketchy, narrow and fragmentary. Regulation of tungsten, both in terms of environmental and occupational safety and health, is at present limited in comparison with other metals. This pattern of environmental obscurity has been unequivocally disrupted by the events of Fallon, Nevada and the possible implication of tungsten to an acute lymphocytic leukemia (ALL) cluster. Tungsten is now the focus of scrutiny as it currently occupies the top of to do lists of various regulatory, health and environmental agencies. The occurrence of a childhood leukemia cluster in Fallon, Nevada prompted a wide investigation that involved several local, state and federal agencies led by the Centers of Disease Control (CDC). In essence, the objective of this investigation was to assess whether environmental causes were responsible for the cluster. The 16 reported leukemia cases within the time frame of 1997-2001, were well above the average for Nevada (3.0 cases/100,000 children/5 years). Several possible causes were proposed, such as jet fuel (JP-8) from a nearby military base or from a JP-8 pipeline running through the city, high levels of arsenic and other metals in the drinking water supplies, industrial pollution from a local tungsten smelting facility, and agrochemical contamination resulting from agricultural pesticide/fungicide use. Although the exact causes of leukemia are not well known, genetic and/or environmental factors may trigger the disease including ionizing and electromagnetic radiation, infectious and chemical agents. Physiologically, it exists as an ion in the body.(PMID: 16343746). Tungsten is a chemical element with the chemical symbol W and atomic number 74. Tungsten is the only metal from the third transition series that is known to occur in biomolecules, where it is used in a few species of bacteria. It is the heaviest element known to be used by any living organism. Tungsten interferes with molybdenum and copper metabolism, and is somewhat toxic to animal life. [Wikipedia]. Tungsten is found in many foods, some of which are orange bell pepper, black walnut, parsnip, and eggplant.

C4H6O2 (86.0368)

Gamma-butyrolactone (GBL), also known as 1,4-butanolide or 1,4-lactone, belongs to the class of organic compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. GBL can also be classified as a tetrahydrofuran substituted by an oxo group at position 2. Gamma-butyrolactone is soluble in ethanol and moderately miscible in water. Gamma-butyrolactone is a sweet, caramel, and creamy tasting compound. Gamma-butyrolactone exists in all living species, ranging from bacteria to plants to humans. It can be endogenously produced from gamma-aminobutyrate and is the precursor of gamma-hydroxybutyrate. Outside of the human body, gamma-butyrolactone has been detected, but not quantified in, several different foods, such as pepper (c. annuum), yellow bell peppers, orange bell peppers, soy beans, evergreen blackberries and a variety of wines (at a concentration of 5 ug/mL) (PMID: 15939164). This could make gamma-butyrolactone a potential biomarker for the consumption of these foods. Gamma-butyrolactone is rapidly converted into gamma-hydroxybutyrate by paraoxonase (lactonase) enzymes, found in the blood. Because it can serve as a prodrug for gamma-hydroxybutyrate (GHB), Gamma-butyrolactone is commonly used as a recreational CNS depressant with effects similar to those of barbiturates. Industrially gamma-butyrolactone is used as a common solvent for polymers and alcohols, a chemical intermediate, a raw material for pharmaceuticals, and as a paint stripper, superglue remover, and a stain remover. Present in morello cherry, melon, pineapple, blackberry, quince, strawberry jam, wine, soybeans, black tea, Bourbon vanilla, wheat bread, crispbread and other breads.

Diluent in colour additive mixtures for food us Cyclohexane appears as a clear colorless liquid with a petroleum-like odor. Used to make nylon, as a solvent, paint remover, and to make other chemicals. Flash point -4 °F. Density 6.5 lb / gal (less than water) and insoluble in water. Vapors heavier than air. Cyclohexane is an alicyclic hydrocarbon comprising a ring of six carbon atoms; the cyclic form of hexane, used as a raw material in the manufacture of nylon. It has a role as a non-polar solvent. It is a cycloalkane and a volatile organic compound. Cyclohexane is an organic compound with the molecular formula C6H12. It is a colorless, flammable liquid with a distinctive sweet odor. Cyclohexane is a saturated hydrocarbon, consisting of a six-membered ring of carbon atoms, with each carbon atom bonded to two hydrogen atoms. The carbon-carbon bonds in the ring are of equal length and angle, giving cyclohexane a regular, symmetrical structure. Due to its ring structure, cyclohexane is more stable than the open-chain aliphatic hydrocarbons with the same number of carbon atoms. It is widely used in industry as a solvent for oils, waxes, and alkaloids, and as a starting material in the production of various chemicals, including adipic acid, cyclohexanol, and cyclohexene. Cyclohexane is also used in the manufacturing of nylon and other synthetic fibers. Cyclohexane exhibits a unique conformational behavior, where it can exist in several different forms, known as conformers. The two most stable conformers are the chair form and the boat form. The chair conformation is the most stable and is characterized by alternating axial and equatorial hydrogen atoms, while the boat conformation has two pairs of hydrogen atoms that are close together, creating strain in the molecule. In terms of its physical properties, cyclohexane has a boiling point of around 80.7°C and a melting point of approximately 6.47°C. It is relatively insoluble in water but miscible with many organic solvents. Cyclohexane is non-polar and therefore does not dissolve ionic compounds or highly polar molecules. Cyclohexane.

2-Hydroxyglutarate

C5H8O5 (148.0372)

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

Hyoscyamine

C17H23NO3 (289.1678)

(S)-atropine is an atropine with a 2S-configuration. It is functionally related to a (S)-tropic acid. It is a conjugate base of a (S)-atropinium. Hyoscyamine is a tropane alkaloid and the levo-isomer of [atropine]. It is commonly extracted from plants in the Solanaceae or nightshade family. Research into the action of hyoscyamine in published literature dates back to 1826. Hyoscyamine is used for a wide variety of treatments and therapeutics due to its antimuscarinic properties. Although hyoscyamine is marketed in the United States, it is not FDA approved. Hyoscyamine as a natural plant alkaloid derivative and anticholinergic that is used to treat mild to moderate nausea, motion sickness, hyperactive bladder and allergic rhinitis. Hyoscyamine has not been implicated in causing liver enzyme elevations or clinically apparent acute liver injury. L-Hyoscyamine is a natural product found in Datura ferox, Crenidium spinescens, and other organisms with data available. Hyoscyamine is a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity. Hyoscyamine functions as a non-selective, competitive antagonist of muscarinic receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal tract. These inhibitory effects cause a decrease in saliva, bronchial mucus, gastric juices, and sweat. Furthermore, its inhibitory action on smooth muscle prevents bladder contraction and decreases gastrointestinal motility. The 3(S)-endo isomer of atropine.

Cyclohexane

C6H12 (84.0939)

Cyclohexane appears as a clear colorless liquid with a petroleum-like odor. Used to make nylon, as a solvent, paint remover, and to make other chemicals. Flash point -4 °F. Density 6.5 lb / gal (less than water) and insoluble in water. Vapors heavier than air. Cyclohexane is an alicyclic hydrocarbon comprising a ring of six carbon atoms; the cyclic form of hexane, used as a raw material in the manufacture of nylon. It has a role as a non-polar solvent. It is a cycloalkane and a volatile organic compound. Cyclohexane is an organic compound with the molecular formula C6H12. It is a colorless, flammable liquid with a distinctive sweet odor. Cyclohexane is a saturated hydrocarbon, consisting of a six-membered ring of carbon atoms, with each carbon atom bonded to two hydrogen atoms. The carbon-carbon bonds in the ring are of equal length and angle, giving cyclohexane a regular, symmetrical structure. Due to its ring structure, cyclohexane is more stable than the open-chain aliphatic hydrocarbons with the same number of carbon atoms. It is widely used in industry as a solvent for oils, waxes, and alkaloids, and as a starting material in the production of various chemicals, including adipic acid, cyclohexanol, and cyclohexene. Cyclohexane is also used in the manufacturing of nylon and other synthetic fibers. Cyclohexane exhibits a unique conformational behavior, where it can exist in several different forms, known as conformers. The two most stable conformers are the chair form and the boat form. The chair conformation is the most stable and is characterized by alternating axial and equatorial hydrogen atoms, while the boat conformation has two pairs of hydrogen atoms that are close together, creating strain in the molecule. In terms of its physical properties, cyclohexane has a boiling point of around 80.7°C and a melting point of approximately 6.47°C. It is relatively insoluble in water but miscible with many organic solvents. Cyclohexane is non-polar and therefore does not dissolve ionic compounds or highly polar molecules. Cyclohexane.
