Homovanillic acid (HOC6H3(OCH3)CH2COOH; synonyms: 3-methoxy-4-hydroxyphenyl acetic acid; HVA; 4-hydroxy-3-methoxy-benzeneacetic acid; 4-hydroxy-3-methoxyphenylacetic acid) is a major catecholamine metabolite and is produced by the consecutive action of monoamine oxidase and catechol-O-methyl transferase on dopamine. It is used as a reagent to detect oxidative enzymes, and is associated with dopamine levels in the brain.
