Antioxidants

What are antioxidants and what do they do?

In the life cycle of normal tissue cells, oxygen molecules are present and usefull. These oxygen molecules travel in pairs. Sometimes one of the pair will be used and the other is left alone. That lone oxygen molecule is called a "free radical". Free radicals easily attach onto cells causing an effect, much like that of rust, called oxidative damage, which can bring about intense cell damage and interferes with the cell’s ability to function properly. Over time this may lead to cancer or cardiovascular disease, arthritis, Alzheimer’s, or even AIDS.

Antioxidants are cells that neutralize free radicals because they supply a positive charge to the unpaired oxygen so it cannot damage cells. This renders the free radical useless and the threat is gone. Antioxidants can also prevent oxidation by "guarding" or creating barriers around cell tissue and bonding with free radicals as they attack.

Superoxide dismutase is a naturally occurring enzyme which protects the body against active oxygen species by scavenging excess superoxide.
