Abstract
The oxidation reaction of NADH with synthetic melanin from L-dopa was investigated under various physicochemical conditions by spectrophotometric measurements and ESR spectroscopy. The different amounts of NADH oxidized and the effects on the formation and decay of melanin free radicals were compared. Some hypotheses on a common physical mechanism involved in electron transfer reaction and in electron excitation through a liquid-solid interface are presented.
