Abstract
Hydrogen peroxide, formed directly or as a product of superoxide dismutation, can oxidize ferrocytochrome c at rates comparable to those at which ferricytochrome c is reduced by superoxide. This reoxidation can significantly affect estimates of rates and amounts of superoxide production using absorbance changes for cytochrome c at 550 nm as the assay. The oxidation can be inhibited by catalase.Keywords
