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….

Protective roles of inorganic nitrate in health and diseases

Sources of Nitrites in Organisms Nitrites in organisms can originate from both endogenous (internal) and exogenous (external) sources. Understanding these sources is crucial for comprehending the role of nitrites in human physiology and their potential health impacts. Endogenous Sources Exogenous Sources Physiological Relevance of Nitrites In summary, nitrites in organisms originate from both internal metabolic…
