Metabolite Identification
Common Namep-Aminobenzoic acid
Description4-Aminobenzoic acid, also known as paba or p-aminobenzoate, belongs to the class of organic compounds known as aminobenzoic acids. These are benzoic acids containing an amine group attached to the benzene moiety. 4-Aminobenzoic acid exists as a solid, possibly soluble (in water), and a moderately basic compound (based on its pKa) molecule. 4-Aminobenzoic acid exists in all living species, ranging from bacteria to humans.
