Interrelationship between oxidative damage and antioxidant enzyme activities: an easy and rapid experimental approach

Abstract

This article describes a method for determining some antioxidant enzyme activities (catalase and/or glutathione peroxidase) and the oxidative status (protein oxidative damage and/or lipid peroxidation) of human blood. However, the main objective of the work is to illustrate the relationship between antioxidant defences and oxidative damage, showing to students their correlation and the general importance of the biochemical regulation in health and diseases.
