According to Wikipedia:
"An antioxidant is a molecule able to delay or prevent oxidation of other molecules. Oxidation is a chemical reaction of electron transfer of a substance to an oxidizing agent . Oxidation reactions can produce free radicals Starting chain reactions that damage cells . Antioxidants terminate these reactions by removing free radical intermediates and inhibit other oxidation reactions oxidized themselves. Because of this is that antioxidants are often reducing agents such as thiols or polyphenols. Although oxidation reactions are crucial for life, can also be harmful, so plants and animals maintain complex systems of multiple types of antioxidants such as glutathione, vitamin C, vitamin E and enzymes such as catalase, superoxide dismutase and various peroxidases. Low levels of antioxidants or inhibition of antioxidant enzymes causes oxidative stress and can damage or kill cells. Oxidative stress has been associated with the pathogenesis of many human diseases, which is why the use of antioxidants in pharmacology is intensively studied, particularly as a treatment for stroke and neurodegenerative diseases. However, it is unknown whether oxidative stress is the cause or the consequence of such diseases. Antioxidants are also widely used as ingredients in dietary supplements the hope of maintaining health and preventing diseases such as cancer and heart disease. Although some studies have suggested that antioxidant supplements have health benefits, other large clinical trials did not detect any benefit for the formulations tested, and excess supplementation can be harmful. Besides these applications in medicine, antioxidants have many industrial applications, such as preservatives in foods and cosmetics and preventing the degradation of rubber and gasoline.
