Dopamine (DA, contracted from 3,4-dihydroxyphenethylamine) is an organic chemical of the catecholamine and phenethylamine families that plays several important roles in the brain and body.
The precursor for dopamine is the amino acid tyrosine. This essential amino acid enters your body and bloodstream through your diet. An active transport mechanism takes up tyrosine from the bloodstream and concentrates it within the brain (particularly in the substantia nigra, midbrain, and hypothalamus).
