[EC:1.11.1.15] EOG8ZGRTS GO:0004601 1/8 peroxidase activity molecular_function "Catalysis of the reaction: donor + hydrogen peroxide = oxidized donor + 2 H2O." [EC:1.11.1.7] EOG8ZGRTS GO:0016209 1/8 antioxidant activity molecular_function "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." [ISBN:0198506732]
