An antioxidant is a molecule that helps prevent the oxidation of other molecules in organic methods. Oxidation encompasses a wide selection of chemical reactions and changes, this kind of as the burning of gas, or the rusting of metal. In biology, oxidation reactions require the two necessary reactions, such as the burning of food items for fuel, or the fat burning capacity of numerous chemical compounds, but it also requires oxidative tension, a relatively random and destructive process by which cost-free radicals create a chain reaction which damages the within of a mobile.
How do anti-oxidants perform?
Antioxidants operate primarily by eliminating cost-free radicals, terminating the destructive chain reactions by way of which these free radicals harm cells. Antioxidants do so by reacting with the free radical, and are as a result “employed up” when they terminate the response.
