An antioxidant is a molecule capable of inhibiting the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons from a substance to an oxidizing agent. Oxidation reactions can produce free radicals. In turn, these radicals can start chain reactions that damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols, ascorbic acid or polyphenols. Although oxidation reactions are crucial for life, they can also be damaging; hence, plants and animals maintain complex systems of multiple types of antioxidants, such as glutathione, vitamin C, and vitamin E as well as enzymes such as catalase, superoxide dismutase and various peroxidases. Low levels of antioxidants, or inhibition of the antioxidant enzymes, cause oxidative stress and may damage or kill cells. As oxidative stress might be an important part of many human diseases, the use of antioxidants in pharmacology is intensively studied, particularly as treatments for stroke and neurodegenerative diseases. However, it is unknown whether oxidative stress is the cause or the consequence of disease. Antioxidants are widely used as ingredients in dietary supplements in the hope of maintaining health and preventing diseases such as cancer, coronary heart disease and even altitude sickness. Although initial studies suggested that antioxidant supplements might promote health, later large clinical trials did not detect any benefit and suggested instead that excess supplementation may be harmful. In addition to these uses of natural antioxidants in medicine, these compounds have many industrial uses, such as preservatives in food and cosmetics and preventing the degradation of rubber and gasoline.

Q. What are three vitamins that also act as antioxidants? Asked by Caitlin - Wed Nov 21 00:47:49 2007 - - 2 Answers - 0 Comments A. Atoms are composed of a nucleus, neutrons, protons and electrons. Electrons are positioned in various shells that surround an atom. Each shell has a certain maximum number of electrons it can hold. The outer shell is the critical shell. Atoms that have full outer shells maintain their chemical properties and bond normally with adjacent atoms. However, atoms that do not have full outer shells will try to react chemically with adjacent atoms in an attempt to fill their outer shell. The incomplete outer shell will try to gain or release electrons to fill or empty their outer shell. or it will attempt to share their outer shell electrons by bonding together with adjacent atoms in order to complete their outer shell. Unfortunately, this… [cont.] Answered by Horatio - Wed Nov 21 01:52:23 2007 From Yahoo Answer Search: "Antioxidants" See also:
