WebStructures of Folate • Folate (also called pteroylglutamate or pteroylmonoglutamate) is composed of three parts that are all required for vitamin activity. The three parts are: (a) 2-amino-4-hydroxypteridine, more commonly called pterin or pteridine, that is conjugated by a methylene group (— CH2 —) to (b) Para-aminobenzoic acid (PABA) to form pteroic acid; … WebPABA is needed in enzymatic reactions that produce folic acid, which acts as a coenzyme in the synthesis of purines and pyrimidines, the building-blocks of DNA. Mammals do not synthesize their own folic acid so they are unaffected by PABA inhibitors, which selectively kill …
