anion radical

It has been suggested that superoxide anion radicals and hydroxyl radicals may be formed and that lipid peroxidation could be responsible for the toxicity of cephaloridine.

Enzymes in plants called superoxide dismutases remove superoxide anion radicals from cells, but increasing the amount and activity of these enzymes is difficult and not the most efficient way to go about improving the durability of plants.

Rather than proceeding through a Type I or Type II photooxygenation mechanism, some investigators have chosen to use 9,10-dicyanoanthracene (DCA) as a photosensitzer, leading to the reaction of an indolizine derivative with the superoxide anion radical.
