Descriptions Names[Advanced Search]

Inhibition of the reactions brought about by dioxygen (O2) or peroxides. Usually the antioxidant is effective because it can itself be more easily oxidized than the substance protected. The term is often applied to components that can trap free radicals, thereby breaking the chain reaction that normally leads to extensive biological damage. Catalysis of the reaction: donor + H2O2 = oxidized donor + 2 H2O. Catalysis of an oxidation-reduction (redox) reaction in which the peroxide group acts as a hydrogen or electron acceptor. Catalysis of the reaction: 2 ferrocytochrome c + H2O2 = 2 ferricytochrome c + 2 H2O.
