Voltamperemetric method for catalase and superoxidedismutase catalytic properties study
Catalase and superoxidedismutase (SOD) catalytic properties study was carried out by voltamperemetric method. The pH influence on antioxidant properties of catalase and SOD was studied. The optimal pH value of 6.86 at which enzymes show the maximum activity was found. Possible mechanisms of interaction between enzymes and reactive oxygen species were proposed. Antioxidant activity criteria of IC50 superoxidedismutase and some organic copper complexes were determined with spectrophotometric and voltamperemetric methods.
