A substance that, when present at a lower concentration than that of the oxidizable substrate, significantly inhibits or delays oxidative processes, while being itself oxidized. For antioxidants, such as ascorbic acid (Fig. 1), antioxidative activity is by the donation of an electron to a radical derivative. Other antioxidants act by removing an oxidative catalyst and the consequent prevention of the initiation of oxidation. See also: Vitamin C
