| 中文摘要 | the cytochrome c and hydrogen peroxide-dependent oxidation of m-aminophenol was investigated by electrochemistry and spectrophotometry. the results indicated that the hydroxylated species of m-aminophenol have at least two conjugated substituted groups on the ring system (most possibly, its oxidized form 2-hydroxy-4-iminoquinone), and that the degradation of cytochrome c by hydrogen peroxide can also be prevented in the presence of m-aminophenol. the hydroxyl radical scavengers, mannitol and sodium benzoate, almost completely eliminate the hydroxylation of m-aminophenol. but oxo-heme species scavenger, uric acid, does not inhibit the hydroxylation. combining the results of mass spectrum, nuclear magnetic resonance and element analysis with that of spectrophotometry, electrochemistry and chemical scavengers, it is suggested that cytochrome c may act as a peroxidase, which facilitates the hydroxylation and subsequent dimerization of m-aminophenol.
