Metabolite Identification
Common NameGentisic acid
DescriptionGentisic acid, also known as gentisate or 2,5-dioxybenzoate, belongs to the class of organic compounds known as hydroxybenzoic acid derivatives. Hydroxybenzoic acid derivatives are compounds containing a hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxyl and a hydroxyl groups. Gentisic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Gentisic acid exists in all living organisms, ranging from bacteria to humans.
