The antioxidant properties of catalase and superoxide dismutase (SOD) have been studied by voltammetry. The effect of pH on the antioxidant properties of catalase and SOD has been evaluated. It is established that the antioxidant activity of both enzymes is maximum at pH 6.86. Mechanisms of the interaction of enzymes with reactive oxygen species are considered. Antioxidant activity criterion (IC50) for SOD and some copper complexes have been estimated by voltammetry and spectrophotometry.
