WebFolic acid (folate) is a vitamin that humans must take in their diet, as they cannot synthesize it. Bacteria and higher plants can synthesize folate from the bicyclic pteridine ring, p-aminobenzoic acid, and glutamate. Sulfa drugs, which are used to treat certain bacterial infections, are analogues of p -aminobenzoic acid.
