Abstract

Sonolysis of argon-saturated aqueous quinone solutions resulted in an enhancement in ferricytochrome c (Cyt c) reduction. Upon addition of superoxide dismutase, Cyt c reduction was partially inhibited, thus implying a role of superoxide ion in this reduction process. Neither quinone hydrophobicity nor reduction potential exclusively controls the Cyt c reduction enhancement, although a preference for hydrophobicity versus reduction potential is noted.

摘要

对饱和氩气的醌类水溶液进行超声处理，可增强高铁细胞色素c（细胞色素c）的还原。添加超氧化物歧化酶后，细胞色素c的还原受到部分抑制，这表明超氧离子在该还原过程中发挥了作用。尽管观察到对疏水性与还原电位存在偏好，但醌类的疏水性和还原电位均不能单独控制细胞色素c还原的增强。
