Antioxidants definition: Naturally occurring or synthetic substances that inhibit or retard the oxidation of a substance to which it is added. They counteract the harmful and damaging effects of oxidation in animal tissues.
antioxidant definition: naturally occurring or synthetic substances that inhibit or retard the oxidation of a substance to which it is added; counteract the harmful and damaging effects of oxidation.
antioxidant definition: A substance that prevents damage caused by free radicals. Free radicals are highly reactive chemicals that often contain oxygen. They are produced when molecules are split to give products that have unpaired electrons. This process is called oxidation.
Antioxidant definition: 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)
Peroxiredoxins definition: A family of ubiquitously-expressed peroxidases that play a role in the reduction of a broad spectrum of PEROXIDES like HYDROGEN PEROXIDE; LIPID PEROXIDES and peroxinitrite. They are found in a wide range of organisms, such as BACTERIA; PLANTS; and MAMMALS. The enzyme requires the presence of a thiol-containing intermediate such as THIOREDOXIN as a reducing cofactor.
antioxidant activity definition: Inhibition of the reactions brought about by dioxygen (O2) or peroxides. Usually the antioxidant is effective because it can itself be more easily oxidized than the substance protected. The term is often applied to components that can trap free radicals, thereby breaking the chain reaction that normally leads to extensive biological damage.

Total Radical-Trap Antioxidant Potential Measurement definition: The determination of the potential for the antioxidants contained in a biological specimen to buffer free radicals in a solution.
