A group of organic or inorganic substances capable of preventing the genotoxic and carcinogenic effects of free-radical compounds. Antioxidants bind to and neutralize ('scavenge') free radicals, thereby transforming them into non-toxic compounds and blocking their genotoxic and carcinogenic effects. This class of agents includes the vitamins C and E, the carotenoids, and selenium. Organic antioxidants are found in high concentrations in fruits, seeds and vegetables. (NCI04)

Agent used to stabilize a system against oxidative degradation. (Adapted from Medicinescomplete)

A substance that protects cells from the damage caused by free radicals (unstable molecules made by the process of oxidation during normal metabolism). Free radicals may play a part in cancer, heart disease, stroke, and other diseases of aging. Antioxidants include beta-carotene, lycopene, vitamins A, C, and E, and other natural and manufactured substances.
