text: Briefly, the antioxidant activity is exerted by inhibiting the activity of some enzymes (e.g., xanthine oxidase, protein kinase C, ascorbic acid oxidase, cyclooxygenase, lipoxygenase, Na+/K+ ATPase, and cAMP phosphodiesterase) which inhibit the production of ROS species; by scavenging, interrupting the reactions that lead to the lipid peroxidation; by chelating metal ions, mainly iron and copper, that are involved in the process of free radical creation; or by potentiating the action of other antioxidants .
