A chemical which is added to feedstuffs to stop fats breaking down Vitamin E is a commonly used anti-oxidant in fish feeds
A material which, when added to a varnish or an oil, allows the oxidation to progress to the desired stage and then retards subsequent oxidation, thus extending the life of the film
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
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
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 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 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
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 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 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
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
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
