Superoxide ion

Authoring team

The superoxide ion is a free radical generated by the addition of an electron to oxygen. It can be caused by:

  • oxidases e.g. xanthine oxidase, flavin oxidases
  • auto-oxidation in mitochondria

Inactivation may be spontaneous or via the enzyme superoxide dimutase to form the hydrogen peroxide ion.
