1 The oxidation of 3,4-dihydroxyphenylethylamine (dopamine) by O2 catalyzed by tyrosinase yields 4-(2-aminoethyl)-1,2-benzoquinone, with its amino group protonated (o-dopaminequinone-H+), which evolves non-enzymatically through two branches or sequences of reactions, whose respective operations are determined by the pH of the medium.
