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.
