Oxidation is the chemical process in which an atom or a molecule gives up (donates) one or more electrons to another substance. Burning is an example of a rapid process of oxidation. Rusting is an example of a slow process of oxidation.
Oxidation and oxidative stress and oxidative damage: structural damage to cell components such as proteins, lipids, and DNA that is caused by chain reactions set off by harmful free radicals. The chain reactions can be terminated by antioxidants such as Coenzyme Q10.
