Catalase - Wikipedia
WEBCatalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen. [5]
Catalase | Function & Applications | Britannica
WEBcatalase, an enzyme that brings about (catalyzes) the reaction by which hydrogen peroxide is decomposed to water and oxygen. Found extensively in organisms that live in the presence of oxygen, catalase prevents the accumulation of and protects cellular organelles and tissues from damage by peroxide , which is continuously produced by numerous ...
Therapeutic potentials of catalase: Mechanisms, applications, and ...
WEBCatalase, an enzyme ubiquitous in living organisms, plays a pivotal role in mitigating oxidative stress by catalyzing the decomposition of hydrogen peroxide (H 2 O 2) into water and oxygen. Mechanistically, this action prevents the accumulation of reactive oxygen species (ROS) and consequent oxidative damage to cells and tissues.
