| Reactive Oxygen Species Oxygen Radicals | Active Oxygen | Oxygen Species, Reactive | Pro-Oxidants | Oxygen, Active | Pro Oxidants 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. |
