The molecule is an N-acyl-amino acid that is a form of the water-soluble vitamin B9. Its biologically active forms (tetrahydrofolate and others) are essential for nucleotide biosynthesis and homocysteine remethylation. It has a role as a B vitamin, a human metabolite, a nutrient and a mouse metabolite. It is a member of folic acids and a N-acyl-amino acid. It derives from a pteroic acid. It is a conjugate acid of a folate(2-).
