Catalase vs. Peroxidase

Catalasenoun

An enzyme found in the liver that catalyses the decomposition of hydrogen peroxide to water and oxygen.

Catalasenoun

an enzyme found in most plant and animal cells that functions as an oxidative catalyst; it decomposes hydrogen peroxide into hydrogen and water.

Catalase

Catalase 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. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS).

Peroxidasenoun

(enzyme) Any of a class of enzymes that act on substrates such as hydrogen peroxide and organic hydroperoxides such as lipid peroxides.

Peroxidasenoun

any of a group of enzymes (occurring especially in plant cells) that catalyze the oxidation of a compound by a peroxide

Peroxidase

Peroxidases or peroxide reductases (EC number 1.11.1.x) are a large group of enzymes which play a role in various biological processes. They are named after the fact that they commonly break up peroxides.
