Scope note: Moléculas o iones formados por la reducción incompleta de un electrón del oxígeno. Estas especies reactivas intermedias de oxígeno incluyen el SINGLETE DE OXÍGENO, los SUPERÓXIDOS, PERÓXIDOS, el RADICAL HIDROXILO y el ÁCIDO HIPOCLOROSO. Contribuyen a la actividad microbicida de los FAGOCITOS, la regulación de la TRANSDUCCIÓN DE SEÑALES, la EXPRESIÓN GÉNICA y al daño oxidativo de los ÁCIDOS NUCLEICOS, PROTEÍNAS y LÍPIDOS.

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.
