Pharmacology

Superoxide is a reactive oxygen species (ROS) containing a negatively charged dioxygen group. Superoxides are produced by phagocytic cells of the immune system to kill invading microorganisms and are neutralized by the enzyme superoxide dismutase (SOD) to protect host cells from oxidative damage.
