===Dopamine biosynthesis===
{{Catecholamine and trace amine biosynthesis|caption=In humans, [[catecholamine]]s and phenethylaminergic [[trace amine]]s are derived from the amino acid [[phenylalanine]]. It is well established that dopamine is produced from L-tyrosine via L-dopa; however, recent evidence has shown that CYP2D6 is expressed in the human brain and catalyzes the biosynthesis of dopamine from L-tyrosine via ''p''-tyramine.<ref name="CYP2D6 tyramine-dopamine metabolism" /> Similarly, CYP2D6 also metabolizes [[m-tyramine|''m''-tyramine]] into dopamine.<ref name="CYP2D6 tyramine-dopamine metabolism" />}}
