MSH: Highly reactive compounds produced when oxygen is reduced by a single electron. In biological systems, they may be generated during the normal catalytic function of a number of enzymes and during the oxidation of hemoglobin to METHEMOGLOBIN. In living organisms, SUPEROXIDE DISMUTASE protects the cell from the deleterious effects of superoxides.,CSP: compound containing the highly reactive surperoxide radical O2-, which is produced by reduction of molecular oxygen in many biological oxidations.
