Bovine Superoxide dismutase-polyethylene glycol

Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. Hydrogen peroxide is also damaging, but less so, and is degraded by other enzymes such as catalase. Thus, SOD is an important antioxidant defense in nearly all living cells exposed to oxygen. https://www.creative-enzymes.com/product/Bovine-Superoxide-Dismutasepolyethylene-Glycol_1607.html
