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]

C30H39N9O12 (717.2718054)


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.
