Definition of antioxidant in English English dictionary: Acting or having agents that act against oxidation; Any substance that acts to slow or prevent the oxidation of another chemical; In nutrition, one of a group of vitamins that act against the effects of free radicals; any natural or synthetic substance that prevents or impedes destructive oxidation reactions (oxidation is what happens when the body literally "burns up" slowly) These include Vitamins C and E, the minerals selenium and germanium, the enzymes catalase and superoxide dismutase (SOD), coenzyme Q-10, and some amino acids These help protect cells from the damaging effects of oxygen free radicals, which are highly reactive compounds created during normal cell metabolism Antioxidants scavenge free radicals, convert them to harmless substances, absorb them or attach to them before the free radicals can attack normal tissues, destroy cellular proteins or enzymes, or even cause DNA mutations leading to cancer; substance that inhibits oxidation or inhibits reactions promoted by oxygen or peroxides; Antioxidants are substances that prevent or slow oxidation Research shows that some antioxidants can prevent cell damage Antioxidants neutralize free radicals by donating an electron to end the "stealing" reaction Antioxidants do not become free radicals themselves because they are stable with or without the electron they donate They are scavengers that help to prevent cell and tissue damage that may eventually lead to disease; A substance that retards oxidation Antioxidants are added to meat and poultry products to prevent or slow oxidative rancidity of fats that causes browning Used with fresh meats; Substance used to prevent or delay deterioration, especially upon exposure to air Prevents fats from spoiling; Antioxidants protect key cell components by neutralizing the damaging effects of "free radicals," natural byproducts of cell metabolism Free radicals form when oxygen is metabolized, or burned by the body They travel through cells, disrupting the structure of other molecules, causing cellular damage Such cell damage is believed to contribute to aging and various health problems; a molecule that can neutralize free radicals before they interact with living tissue; a chemical which combines with free radicals and/or other chemicals that release free radicals that would otherwise attack molecules in the body, and abnormally oxidize them Susceptible molecules include such vital entities as DNA, RNA, lipids (fats), and proteins The antioxidant, by reacting with the oxidant, protects these important molecules from being damaged Examples of antioxidants include vitamins A, C, E, B-1, B-5, B-6, the amino acid cysteine, the food antioxidants BHT and BHA, and the minerals selenium and zinc; A chemical compound or substance that inhibits oxidation; A substance that hinders oxidation In the lung, oxidant molecules are suspected to contribute to a variety of serious conditions; antioxidants can be an important defense; a chemical substance which selectively reacts with oxygen to inhibit or prevent oxidation; Additives which inhibit oxidation at normal or elevated temperatures; The presence of such substances slows or interferes with the reaction of the fat or oil with oxygen Addition of the antioxidant(s) retards rancidity development and increases stability and shelf-life; A compound which retards oxidation; acting or havirng agents that act against oxidation; a chemical which reduces oxidative damage to cells, often by detoxifying free radicals (highly reactive chemicals); Compounding ingredient used to retard deterioration caused by oxidation; a substance that protects components of a cell from oxidative damage that may occur from light, stress, or metabolic processes Some well known antioxidants include compounds normally present in food such as, vitamin E, beta-carotene, the carotenoids lutein and zeaxanthin, vitamin C, zinc, and selenium; A substance that inhibits destructive oxidation events in an organism; A chemical substance added to a plastic resin to minimize or prevent the effects of oxygen attack on the plastic, e g , yellowing or degradation Chemical attacks by oxygen can render a plastic brittle or cause it to lose desired mechanical properties; {i} substance that inhibits oxidation; These are agents/compounds which retard oxidation in the human body; Part of a group of vitamins (A, B, C and E) that may help to limit the cellular damage caused by free radicals Studies suggest that certain antioxidants may protect against coronary artery disease; An antioxidant is a substance which slows down the damage that can be caused to other substances by the effects of oxygen. Foods which contain antioxidants are thought to be very good for you. a substance in some foods that cleans the body and protects it from cancer. Any of various compounds added to certain foods, natural and synthetic rubbers, gasolines, and other products to retard autoxidation (combination with oxygen in the air at room temperature) and its effects. Aromatic compounds such as aromatic amines, phenols, and aminophenols delay loss of elasticity in rubber and gummy deposits in gasoline. Preservatives such as tocopherol (vitamin E), propyl gallate, butylated hydroxytoluene (BHT), and butylated hydroxyanisole (BHA) prevent rancidity in fats, oils, and fatty foods. In the body, antioxidants such as vitamins C and E and selenium may reduce oxidation caused by free radicals; a substance that can protect another substance from oxidation; added to foods to keep oxygen from changing the food's color; A substance which inhibits the interaction of oxygen or free radicals with polyunsaturated fats Naturally occurring examples include vitamins C and E; An antioxidant is a substance that slows or prevents oxidation reactions, and is commonly added to prepared foods, vegetable oils and paints to prevent deterioration upon exposure to oxygen; Affects digestive system and nutrition due to its ability to stabilize to fats and oils by delaying oxidation Agents that prevent damage to cells by inhibiting oxidation and by trapping free radicals to top of page; A substance that inhibits oxidation, and is capable of counteracting the damaging effects of oxidation in body tissue; antiossidante
antioxidants: Micro-nutrients that destroy or neutralize free radicals
antioxidants: Substances such as Vitamins A, C and E and minerals such as copper, magnesium and zinc Believed to destroy free radicals, which some scientists think may not only accelerate aging but also contribute to the formation of cancers and cataracts
