Superoxide dismutase (SOD) is an important antioxidant role of the main enzyme in the elimination of its catalytic disproportionation of oxygen and hydrogen peroxide toxic superoxide anion radical (O2 -). Three superoxide dismutase isoenzymes have been identified in mammalian cells, copper and zinc containing superoxide dismutase (Cu / Zn superoxide dismutase, SOD1), the dimer is expressed in the cytoplasm; containing manganese superoxide dismutase enzyme (manganese superoxide dismutase (SOD), start the SOD2), expressed as a tetramer in the mitochondria; and tetramer extracellular superoxide dismutase (EC superoxide dismutase of SOD3). Is the reason about 20% of amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease gene mutation in Cu / Zn SOD.Read More: Superoxide dismutase suppliers
