Reactive oxygen species:

Including oxygen in free radical state (such as superoxide radical and hydroxyl radical) and hydrogen peroxide which is not free radical. Free radical is the product of losing an electron in the outermost even electron of an atom. They can also be produced by exogenous factors, which can easily react with surrounding molecules, release energy and cause cell damage.

There are both AOS production system and antioxidant system that antagonizes AOS production in cells. Usually a small amount of AOS is eliminated by intracellular and extracellular antioxidants such as superoxide dismutase, glutathione peroxidase, catalase and vitamin E.

During redox reactions such as hypoxia-ischemia, cell phagocytosis, chemical radiation injury, inflammation and aging, AOS production increases, and lipids, protein and DNA are peroxidized.
