[PAR] [TLE] Homovanillic acid [SEP] Homovanillic acid (HVA) is a major catecholamine metabolite that is produced by a consecutive action of monoamine oxidase and catechol-O-methyltransferase on dopamine.  Homovanillic acid is used as a reagent to detect oxidative enzymes, and is associated with dopamine levels in the brain. [PAR] [TLE] Dopamine [SEP] Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is an organic chemical of the catecholamine and phenethylamine families that plays several important roles in the brain and body.  It is an amine synthesized by removing a carboxyl group from a molecule of its precursor chemical L-DOPA, which is synthesized in the brain and kidneys.  Dopamine is also synthesized in plants and most animals.
