Related to dopa: dopamine, DOPA decarboxylase


An amino acid, C9H11NO4, that occurs widely in animals and plants. In humans and other mammals, it is formed in the liver from tyrosine and converted to dopamine in the brain.



(Biochemistry) See L-dopa


(ˈdoʊ pə)

an amino acid, C9H11NO4, formed from tyrosine in the liver during melanin and epinephrine biosynthesis. Compare L-dopa.

L-Tyrosine is an amino acid that is the precursor to dopa, and dopa is a chemical that's necessary to manufacture dopamine.
Of the three enzymes, tyrosinase is the most critical because in the de novo synthesis pathway of melanin it catalyses the two rate-limiting steps; namely, the hydroxylation of tyrosine to DOPA and the oxidation of DOPA to dopaquinone.
