Temple University: Slide 1 Human Catalase An enzyme (protein that changes the rate of chemical reactions) found in all living organisms. Its function is to decompose Hydrogen Peroxide (bodily toxin) into Water and Oxygen molecules: A protein composed of four peptide chains, over 500 Amino Acids long. Molecular Mass (weight) of 59,800 amu. This is what our data contains. 2 H 2 O 2 → 2 H 2 O + O 2
