Catalase is a high activity enzyme that facilitates the decomposition of hydrogen peroxide to harmless oxygen and water. This is a protective function to prevent cell damage that could be caused by hydrogen peroxide, a powerful oxidizing agent. Catalase is found in nearly all animals as well as many microbes and plants - the catalase sold here is sourced from derived from Fungi, Aspergillus niger. It is also used widely in industrial processes.
