Question

give a detailed description of superoxide

Answer 1

Most of these cells have superoxidedismutase and another enzyme, catalase (or another enzyme, glutathione peroxidase), which converts the hydrogen peroxide to oxygen and water. In other words, the combination of superoxide dismutase and catalase removes oxygen radicals and thus is protective for cells in the body.

Answer 2

A superoxide, also known as hyperoxide,is a compound that contains the superoxide anion with the chemical formula O−
2.The systematic name of the anion is dioxide(1−). The reactive oxygen anion superoxide is particularly important as the product of the one-electron reduction of dioxygen O2, which occurs widely in nature. Whereas molecular oxygen (dioxygen) is a diradical containing two unpaired electrons, the addition of a second electron fills one of its two degenerate molecular orbitals, leaving a charged ionic species with single unpaired electron and a net negative charge of −1. Both dioxygen and the superoxide anion are free radicals that exhibit paramagnetism.
