Tetrahydropteroyltri-L-glutamic acid
C29H37N9O12 (703.2561562000001)
Tetrahydropteroyltri-L-glutamic acid (CAS: 4227-85-4), also known as (6S)-H4pteglu3, belongs to the class of organic compounds known as tetrahydrofolic acids and derivatives. These are heterocyclic compounds based on the 5,6,7,8-tetrahydropteroic acid skeleton conjugated with at least one L-glutamic acid unit (or a derivative thereof). Tetrahydropteroyltri-L-glutamic acid is a strong basic compound (based on its pKa). In humans, this compound is produced by the bacteria in the gut and may be found in feces or urine. Tetrahydropteroyltri-L-glutamica cid exists in all living species, ranging from bacteria to humans. Tetrahydropteroyltri-L-glutamic acid is an intermediate in the synthesis of methionine by bacteria. It is a substrate for the enzyme 5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase which catalyzes the reaction 5-methyltetrahydropteroyltri-L-glutamic acid + L-homocysteine = tetrahydropteroyltri-L-glutamic acid + L-methionine. A human metabolite taken as a putative food compound of mammalian origin [HMDB]
5-Methyltetrahydropteroyltri-L-glutamic acid
5-Methyltetrahydropteroyltri-L-glutamic acid (CAS: 13061-55-7) is formed during the reaction between the carbonyl group of 5-methyltetrahydropteroate and the amine group on one end of three replicates of glutamate. It is involved in several pathways as a product of enzymatic reduction such as in tetrahydrofolate biosynthesis II and methionine biosynthesis I, II, and III. It is also involved in several pathways as a product of enzymatic oxidation such as in the pathways folate polyglutamylation I and carbon tetrachloride degradation II. In humans, this compound is produced by the bacteria in the gut and may be found in feces or urine. 5-Methyltetrahydropteroyltri-L-glutamate is formed under reaction between carbonyl group of 5-Methyltetrahydropteroate and amine group on one end of three replicates of glutamate. It is involved in several pathways such as tetrahydrofolate biosynthesis II, methionine biosynthesis I,II,III as a product of enzymatic reduction; while in pathways folate polyglutamylation I and carbon tetrachloride degradation II as a product of enzymatic oxidation. [HMDB]. 5-Methyltetrahydropteroyltri-L-glutamate is found in many foods, some of which are common cabbage, chives, lime, and garden rhubarb.
Hydrogen Ion
Hydrogen ion, also known as proton or h+, is a member of the class of compounds known as other non-metal hydrides. Other non-metal hydrides are inorganic compounds in which the heaviest atom bonded to a hydrogen atom is belongs to the class of other non-metals. Hydrogen ion can be found in a number of food items such as lowbush blueberry, groundcherry, parsley, and tarragon, which makes hydrogen ion a potential biomarker for the consumption of these food products. Hydrogen ion exists in all living organisms, ranging from bacteria to humans. In humans, hydrogen ion is involved in several metabolic pathways, some of which include cardiolipin biosynthesis cl(i-13:0/a-25:0/a-21:0/i-15:0), cardiolipin biosynthesis cl(a-13:0/a-17:0/i-13:0/a-25:0), cardiolipin biosynthesis cl(i-12:0/i-13:0/a-17:0/a-15:0), and cardiolipin biosynthesis CL(16:1(9Z)/22:5(4Z,7Z,10Z,13Z,16Z)/18:1(11Z)/22:5(7Z,10Z,13Z,16Z,19Z)). Hydrogen ion is also involved in several metabolic disorders, some of which include de novo triacylglycerol biosynthesis TG(20:3(8Z,11Z,14Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)/22:5(7Z,10Z,13Z,16Z,19Z)), de novo triacylglycerol biosynthesis TG(18:2(9Z,12Z)/20:0/20:4(5Z,8Z,11Z,14Z)), de novo triacylglycerol biosynthesis TG(18:4(6Z,9Z,12Z,15Z)/18:3(9Z,12Z,15Z)/18:4(6Z,9Z,12Z,15Z)), and de novo triacylglycerol biosynthesis TG(24:0/20:5(5Z,8Z,11Z,14Z,17Z)/24:0). A hydrogen ion is created when a hydrogen atom loses or gains an electron. A positively charged hydrogen ion (or proton) can readily combine with other particles and therefore is only seen isolated when it is in a gaseous state or a nearly particle-free space. Due to its extremely high charge density of approximately 2×1010 times that of a sodium ion, the bare hydrogen ion cannot exist freely in solution as it readily hydrates, i.e., bonds quickly. The hydrogen ion is recommended by IUPAC as a general term for all ions of hydrogen and its isotopes. Depending on the charge of the ion, two different classes can be distinguished: positively charged ions and negatively charged ions . Hydrogen ion is recommended by IUPAC as a general term for all ions of hydrogen and its isotopes. Depending on the charge of the ion, two different classes can be distinguished: positively charged ions and negatively charged ions. Under aqueous conditions found in biochemistry, hydrogen ions exist as the hydrated form hydronium, H3O+, but these are often still referred to as hydrogen ions or even protons by biochemists.
