superoxide dismutase
superoxide dismutase (SOD) A widely distributed enzyme that removes the superoxide radical (O
2·), with the formation of molecular oxygen and hydrogen peroxide, in the following reaction: O
2· + O
2· + 2H
+ → O
2 + H
2O
2 The hydrogen peroxide formed is removed by the action of
catalase. The superoxide anion, which damages tissues, is a
free radical formed by the partial reduction of molecular oxygen; it is produced during the metabolic breakdown of various toxins (including drugs and chemical poisons) and as part of the immune response to the presence of bacteria and virus-infected cells.
