Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals). It catalyzes the decomposition of hydrogen peroxide to water and oxygen.
C 0163 (OTTO) Catalase from bovine liver, lyophilized powder, 2,000-5,000 units/mg protein Cas 9001-05-2 - used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less-reactive gaseous oxygen and water molecules.
