[Catalase and peroxidase activity of porphyrins].
Using spectroscopic photometry, the catalase-like and peroxidase-like activities of some metal complexes of hematoporphyrins and tetraphenylporphyrins were detected. The rate constant for hydrogen peroxide degradation by porphyrins was determined. The possible mechanism of catalysis is discussed.
