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: 2 Mn2+ + 2 H+ + H2O2 = 2 Mn3+ + 2 H2O. Catalysis of the reaction: 2 H2O2 = O2 + 2 H2O. Catalysis of the reaction: NADPH + H2O2 = NADP+ + 2 H2O. Catalysis of the reaction: thioredoxin + H2O2 = thioredoxin disulfide + H2O. Catalysis of the reaction: 2 glutathione + H2O2 = oxidized glutathione + 2 H2O. Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. Catalysis of the reaction: 2 R-H + 2 chloride + H2O2 = 2 R-Cl + 2 H2O. Catalysis of the reaction: donor + H2O2 = oxidized donor + 2 H2O. Catalysis of the reaction: 1,2-bis(3,4-dimethoxyphenyl)propane-1,3-diol + H2O2 = veratraldehyde + 1-(3,4-dimethylphenyl)ethane-1,2-diol + 4 H2O. Catalysis of the reaction: 2 R-H + 2 bromide + H2O2 = 2 R-Br + 2 H2O. Enzymes with this activity often accept other halide ions as substrates, including chloride and iodide. Catalysis of the reaction: iodide + H2O2 = iodine + 2 H2O. Catalysis of the reaction: L-ascorbate + H2O2 = dehydroascorbate + 2 H2O. Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. Catalysis of the reactions: Reactive Black 5 + H2O2 = oxidized Reactive Black 5 + 2 H2O and donor + H2O2 = oxidized donor + 2 H2O. Catalysis of the reaction: tryparedoxin + H2O2 = tryparedoxin disulfide + H2O. Catalysis of the reaction: 2 ferrocytochrome c + H2O2 = 2 ferricytochrome c + 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: NADH + H+ + H2O2 = NAD+ + 2 H2O. Catalysis of the reaction: palmitate + 2 H2O2 = pentadecanal + CO2 + 3 H2O.
