Reactive Oxygen Species: Molecules or ions formed by the incomplete one-electron reduction of oxygen. These reactive oxygen intermediates include Singlet oxygen; Superoxides; Peroxides; Hydroxyl radical; and Hypochlorous acid. They contribute to the microbicidal activity of Phagocytes, regulation of signal transduction and gene expression, and the oxidative damage to Nucleic acids; Proteins; and Lipids.
