Metabolite Identification
Common NameHeptaglutamyl folic acid
DescriptionHeptaglutamyl folic acid is a naturally occurring form of folate. In contrast to synthetic folic acid, natural food folates are predominantly polyglutamates with a variable number of glutamate residues. (PMID 15831124 ). Approximately two-thirds of total folate intake from a mixed unfortified diet is in the polyglutamyl form, derived mainly from vegetables. These polyglutamates need to be hydrolysed to the monoglutamate form for normal absorption in the proximal small intestine. This process is controlled by the intestinal brush-border enzyme glutamate carboxypeptidase II (GCPII). (PMID 12042451 ).
