MeSH Heading: Reactive Oxygen Species
Tree Number(s): D01.339.431; D01.650.775
Unique ID: D017382
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D017382
Scope Note: 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.
Entry Term(s): Active Oxygen; Active Oxygen Species; Oxygen Radical; Oxygen Radicals; Oxygen Species, Reactive; Pro-Oxidant; Pro-Oxidants; Reactive Oxygen Intermediates
Registry Number: 0
See Also: Free Radicals; Oxidative Stress; Oxygen Radical Absorbance Capacity
