hydrogen peroxide is the substrate for which enzyme?
catalase
catalases are enzymes that catalyse the conversion of hydrogen peroxide to water and oxygen, using either an iron or manganese cofactor. this protein is localized to peroxisomes in most eukaryotic cells. catalase is an unusual enzyme since, although hydrogen peroxide is its only substrate, it follows a ping-pong mechanism. here, its cofactor is oxidised by one molecule of hydrogen peroxide and then regenerated by transferring the bound oxygen to a second molecule of substrate. despite its apparent importance in hydrogen peroxide removal, humans with genetic deficiency of catalase — "acatalasemia" — or mice genetically engineered to lack catalase completely, suffer few ill effects.

hydrogen peroxide - urea









































hydrogen peroxide - urea (also called hyperol, artizone, urea hydrogen peroxide, and uhp) is a solid composed of equal amounts of hydrogen peroxide and urea. this compound is a white crystalline solid which dissolves in water to give free hydrogen peroxide. often called carbamide peroxide in the dental office, it is used as a source of hydrogen peroxide for bleaching, disinfection, and oxidation. hydrogen peroxide - urea contains solid and water-free hydrogen peroxide, which offers a higher stability and better controllability than liquid hydrogen peroxide when used as an oxidizing agent.
