40 what does catalase do to hydrogen peroxide

Hydrogen Peroxide: the body's best defence system Because hydrogen peroxide actually forms as a product of metabolism and can do some nasty things. It can break apart to yield hydroxyl radicals that attack important biochemicals like proteins and DNA. To protect itself, the body makes catalase, the enzyme that decomposes hydrogen peroxide before it can form hydroxyl radicals. How does catalase break down hydrogen peroxide? - Studybuff Catalase is a key enzyme which uses hydrogen peroxide, a nonradical ROS, as its substrate.

Antioxidant Enzyme Catalase May Help Treat COVID-19 ...

How does pH affect catalase and hydrogen peroxide? What are the effects of pH and temperature to catalase? As the temperature increases toward the optimum point, hydrogen bonds loosen, making it easier for catalase to act on hydrogen peroxide molecules. If the temperature increases beyond the optimum point, the enzyme denatures, and its structure is disrupted.
