2-Hydroxy-4-methoxybenzoic acid (2-Hydroxy-p-anisic Acid) is a predicted metabolite generated by BioTransformer1 that is produced by the metabolism of 3-(2-hydroxy-4-methoxyphenyl)propanoic acid. It is generated by unspecified-gutmicro enzyme via a beta-oxidation-of-carbxoylic-acid reaction. This beta-oxidation-of-carbxoylic-acid occurs in human gut microbiota.
