Abstract
Radiolytically generated hydroxyl radicals degrade cytochrome c. In contrast, ferrocytochrome c is oxidized in the Fe-EDTA-H2O2 system, without loss of any cytochrome c. It is concluded that in the latter system no hydroxyl radicals are formed and that oxidation takes place via a FeO(II)EDTA or Fe(II)-H2O2-EDTA complex.
摘要
辐射分解产生的羟基自由基会降解细胞色素c。相比之下，亚铁细胞色素c在Fe-EDTA-H₂O₂体系中被氧化，而细胞色素c没有任何损失。可以得出结论，在后一种体系中不会形成羟基自由基，氧化是通过FeO(II)EDTA或Fe(II)-H₂O₂-EDTA络合物进行的。
