antioxidants Substances that slow the rate of oxidation reactions. Various antioxidants are used to preserve foodstuffs and to prevent the deterioration of rubber, synthetic plastics, and many other materials. Some antioxidants inhibit the oxidation reaction by removing oxygen free radicals. Naturally occurring antioxidants with this ability include vitamin E, β-carotene, and glutathione; they limit the cell and tissue damage caused by foreign substances, such as toxins and pollutants, in the body.
