The synthesis and involvement of H2O2 during the early stages of melano-genesis involving the oxidations of DOPA and dopamine (diphenolase activity) were established by two sensitive and specific electrochemical detection systems. Catalase-treated reaction mixtures showed diminished rates of H2O2 production during the autoxidation and tyrosinase-mediated oxidation of both diphenols.
