Overview
Information
4-Aminobenzoic acid (para-Aminobenzoic acid) is an intermediate in the synthesis of tetrahydrofolic acid in many non-mammalian organisms, including bacteria and fungi.
In vivo
Plants produce PABA in their chloroplasts, and store it as a glucose ester (pABA-Glc) in their tissues. Humans lack the enzymes to convert PABA to folate, so require folate from dietary sources such as green leafy vegetables. In humans, PABA is considered nonessential and, although it has been referred to historically as "vitamin Bx", is no longer recognized as a vitamin, because most people have colon bacteria that generate PABA
