DescriptionTetrahydropteroyltri-L-glutamate, 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-glutamate is a strong basic compound (based on its pKa). Tetrahydropteroyltri-L-glutamate exists in all living species, ranging from bacteria to humans. selenomethionine and tetrahydropteroyltri-L-glutamate can be biosynthesized from selenohomocysteine and 5-methyltetrahydropteroyltri-L-glutamate through the action of the enzyme N5-methyltetrahydropteroyltriglutamate-homocysteine methyltransferase. In yeast, tetrahydropteroyltri-L-glutamate is involved in the metabolic pathway called the selenocompound metabolism pathway.
