Difference Between Peroxide and Superoxide

Difference Between Peroxide and Superoxide

Peroxide and superoxide are oxides containing oxygen atoms. The main difference between peroxide and superoxide is that the oxidation state of oxygen in peroxide is -1 whereas the oxidation state of oxygen in superoxide is -1/2.

Is hydrogen peroxide a superoxide?

Superoxide (O2˙̄)2 and hydrogen peroxide (H2O2) are produced by leaks of electrons from donor redox centers of the mitochondrial electron transport chain and associated metabolic enzymes to cause either one-electron or two-electron reduction of oxygen (1, 2).

What does superoxide mean?

Superoxide is a diatomic oxygen, an inorganic radical anion, an oxygen radical and a member of reactive oxygen species. ... In living organisms, SUPEROXIDE DISMUTASE protects the cell from the deleterious effects of superoxides.

What are the examples of Superoxides?

Sodium superoxide (NaO2) can be prepared with high oxygen pressures, whereas the superoxides of rubidium, potassium, and cesium can be prepared directly by combustion in air. By contrast, no superoxides have been isolated in pure form in the case of lithium or the alkaline-earth metals, although…

Which is larger peroxide or superoxide?

Superoxide is larger than peroxide. This is because a peroxide compound is composed of an oxygen-oxygen single bond while the superoxide is composed of an anion O2.

Is RbO2 a superoxide or peroxide?

RbO2 is an ionic compound consisting of Rb+ (alkali metal ion) and O-2 (superoxide ion). The superoxide ion contains an odd number of electrons (17e-) and is, thus, paramangnetic.

Why is superoxide dangerous to the body?

Superoxide may contribute to the pathogenesis of many diseases (the evidence is particularly strong for radiation poisoning and hyperoxic injury), and perhaps also to aging via the oxidative damage that it inflicts on cells.

What causes superoxide?

In cells, superoxide is produced from oxygen molecules by xanthine oxidase, NADPH oxidase and mitochondrial electron transfer systems. Superoxide produced in mitochondria is generated by electrons leaking from the electron transfer system, which is located in the inner membrane of mitochondria.

What is superoxide dismutase used for?

Superoxide dismutase is an enzyme that helps break down potentially harmful oxygen molecules in cells. This might prevent damage to tissues. It is being researched to see if it can help conditions where harmful oxygen molecules are believed to play a role in disease.

How is superoxide created?

4.1. 1(i) Superoxide (O2·) Superoxide, which is an anion radical, is produced by the one-electron reduction of molecular oxygen.

What is meant by peroxide and superoxide?

Peroxide and superoxide are oxides containing oxygen atoms. The main difference between peroxide and superoxide is that the oxidation state of oxygen in peroxide is -1 whereas the oxidation state of oxygen in superoxide is -1/2.

What does peroxide mean?

Peroxide, any of a class of chemical compounds in which two oxygen atoms are linked together by a single covalent bond. Several organic and inorganic peroxides are useful as bleaching agents, as initiators of polymerization reactions, and in the preparation of hydrogen peroxide (q.v.) and other oxygen compounds.
