Catalase

Catalase is a key enzyme in the metabolism of H2O2 and reactive oxygen species (ROS), and its expression and localization is markedly altered in tumors[1]. Free oxygen radical scavenger.
Almost all biological organisms have catalase. It is common in breathing organisms, mainly in the plants' chloroplasts, mitochondria, endoplasmic reticulum, animal liver and red blood cells.Its enzymatic activity provides antioxidant defense mechanism to the body.CAT is a red blood hormone enzyme. Different sources have different structures.The level of activity is different in different tissues.Hydrogen peroxide decomposes faster in the liver than in brain or heart organs, which is due to the high levels of CAT in the liver.

ChEBI: Ethylparaben is an ethyl ester resulting from the formal condensation of the carboxy group of 4-hydroxybenzoic acid with ethanol, It has a role as an antimicrobial food preservative, an antifungal agent, a plant metabolite and a phytoestrogen. It is a paraben and an ethyl ester.
CAT (catalase) is an endogenous antioxidant enzyme, thus conferring protection to cells against damage by ROS (reactive oxygen species). In humans, this gene is localized to chromosome 11p13, which is composed of 12 introns and 13 exons.
