Chemical Information
FooDB Name4-Methoxybenzoic acid
DescriptionFlavouring agent. Food additive listed in the EAFUS Food Additive Database (Jan. 2001) 4-Methoxybenzoic acid, or anisic acid, is an organic compound which is a carboxylic acid found naturally in anise. It is a white crystalline solid which is insoluble in water and soluble in alcohols, ether, and ethyl acetate.; Anisic acid is a phenolic acid, an organic molecule commonly found in anis-seed, a common food spice. Anisic acid is occasionally found in human biofluids. Anisic acid has been characterized as a classical non-competitive inhibitor of the oxidation of L-3,4-dihydroxyphenylalanine (L-DOPA), and the hydroxylation of L-tyrosine catalyzed by tyrosinase (EC 1.14.18.1). Additionally, anisic acid is a metabolite of aniracetam, a cognition enhancer. (PMID: 14577637, 6480763, 6511847, 11597608)
