Metabolite Identification
Common Name5-Methyltetrahydropteroyltri-L-glutamate
Description5-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. In humans, this compound is produced by the bacteria in the gut and may be found in feces or urine.
