Tetrahydropteroyltri-L-glutamic acid
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]
Tetrahydrofolyl-[Glu](n)
Tetrahydrofolyl-[Glu](n) is involved in the folate biosynthesis pathway. Tetrahydrofolyl-[Glu](n) can be reversibly converted into Tetrahydrofolyl-[Glu](2) by folylpolyglutamate synthase [EC:6.3.2.17]. Tetrahydrofolyl-[Glu](n) can be irreversibly converted into tetrahydrofolate by gamma-glutamyl hydrolase [EC:3.4.19.9]. Sample structure image shows the case when n=3.
