Catalase crystals, light micrograph. Catalase is an enzyme that catalyses (speeds up) reactions. As a catalyst it is not used up in the reaction. This enzyme is found in cells where it catalyses the decomposition of hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product that forms during oxidation processes in cells. High concentrations of catalase are found in the liver. Catalase is the fastest known enzyme. It is also used in the rubber industry to form the oxygen in foam rubber. This sample was imaged using a type of interference microscopy called Jamin-Lebedeff microscopy. Interference microscopy is suited for transparent samples. Magnification unknown.
