Detailed explanation-1: -Peroxidases, also known as catalases, are also an oxidoreductase class of enzymes, which catalyze oxidoreduction reactions. The peroxidase enzyme catalyzes the decomposition of hydrogen peroxide into water and molecular oxygen (see illustration). Catalase is a haem-containing enzyme.

Detailed explanation-2: -To protect itself, the body makes catalase, the enzyme that decomposes hydrogen peroxide before it can form hydroxyl radicals.

Detailed explanation-3: -Peroxidase is an enzyme found in a wide variety of organisms, from plants to humans to bacteria. Its function is to break down hydrogen peroxide (H2O2), which is one of the toxins produced as a byproduct of using oxygen for respiration.

Detailed explanation-4: -3 Glutathione Peroxidase. GPX works to remove both H2O2 and lipid peroxides by conversion to water and alcohols, respectively.

Detailed explanation-5: -Peroxidases are enzymes catalyzing redox reactions that cleave peroxides. Their active redox centers have heme, cysteine thiols, selenium, manganese, and other chemical moieties.
