The mechanism of cytochrome C reduction by alkyl radicals. Evidence for multiple reaction pathways.

The reactions of the hydroxyalkyl radicals .CH2OH and (CH3)2.COH with oxidized cytochrome c are for more complex than previously reported. Analysis of the pulse-radiolytic data by kinetic modelling revealed that only about 40% of the alkyl radicals reduce the ferric iron chromophore. Altogether, four different reactions have to be considered for the… CONTINUE READING
