An antioxidant is a molecule that can slow or stop the oxidation, or electron transfer, of other molecules. Antioxidants can be found in food. Antioxidants are molecules that relieve oxidative stress by preventing the formation and oxidation of free radicals. Antioxidants donate one of their electrons or hydrogen to free radicals, stopping their chain reaction.
