Catalase (CAT) is an enzyme found in peroxisomes that catalyzes the decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2).
Catalase (CAT) is a ubiquitous enzyme found in nearly all living organisms that are exposed to oxygen. It is present in a wide variety of tissue types and organisms, including: Catalase is primarily located in peroxisomes, which are organelles that play a key role in the metabolism of hydrogen peroxide and other reactive oxygen species….
