Biosynthesis

Animals, including humans, cannot synthesize folate and therefore must obtain folate from their diet. All plants and fungi and certain protozoa, bacteria, and archaea can synthesize folate de novo through variations on the same biosynthetic pathway. The folate molecule is synthesized from pterin pyrophosphate, para-aminobenzoic acid, and glutamate through the action of dihydropteroate synthase and dihydrofolate synthase. Pterin is in turn derived in a series of enzymatically catalyzed steps from guanosine triphosphate (GTP), while para-aminobenzoic acid is a product of the shikimate pathway.
