Topic of This Issue: Magical Superoxide anion
Superoxide ion (O2·−), which is considered both a radical and an anion with the radical sign ( . ) and a charge of −1, is produced by the one-electron reduction of molecular oxygen and is of great significance as a radical species implicated in diverse chemical and biological systems. Superoxide anion is a byproduct of respiration and a crucial component of the immune defense system. It can be generated from two major sources: the mitochondrial respiratory chain and phagocytic nicotinamide adenine dinucleotide phosphate oxidase (NADPH oxidase). Under normal circumstances, the biological system releases an enzyme, superoxide dismutase (SOD), which specifically maintains the Superoxide anion concentration at an optimal level.
Nevertheless, whe n overproduction of Superoxide anion occurs and/or antioxidant defences are deficient, oxidative stress may develop, damaging important biomolecules and altering their physiological function. For example, Superoxide anion attacks cellular components causing damage to lipids, proteins, and nucleic acids. This can initiate numerous diseases, including cancer, atherosclerosis, rheumatoid arthritis, diabetes, liver damage, sarcopenia, obesity, degenerative diseases that cause urological disorders , fibrous alveoli, bronchopneumonia dysplasia, adult respiratory distress syndrome, Alzheimer's disease and central nervous system disorders.
