Label Id Description
Oxazines D010078 [Six-membered heterocycles containing an oxygen and a nitrogen. ]
Oxazocines D010079 [One ring heterocyclic compounds defined by C6H7NO. Permitted are any degree of hydrogenation, any substituents and any ortho-fused or ortho-peri-fused ring systems. ]
Oxazoles D010080 [Five-membered heterocyclic ring structures containing an oxygen in the 1-position and a nitrogen in the 3-position, in distinction from ISOXAZOLES where they are at the 1,2 positions. ]
Oxazolidinones D023303 [Derivatives of oxazolidin-2-one. They represent an important class of synthetic antibiotic agents. ]
Oxazolone D010081 [Immunologic adjuvant and sensitizing agent. ]
Oxcarbazepine D000078330 [A carbamazepine derivative that acts as a voltage-gated sodium channel blocker. It is used for the treatment of PARTIAL SEIZURES with or without secondary generalization. It is also an inducer of CYTOCHROME P-450 CYP3A4. ]
Oxepins D010082 [Compounds based on a 7-membered heterocyclic ring including an oxygen. They can be considered a medium ring ether. A natural source is the MONTANOA plant genus. Some dibenzo-dioxepins, called depsidones, are found in GARCINIA plants. ]
Oxidants D016877 [Electron-accepting molecules in chemical reactions in which electrons are transferred from one molecule to another (OXIDATION-REDUCTION). ]
Oxidants, Photochemical D010083 [Compounds that accept electrons in an oxidation-reduction reaction. The reaction is induced by or accelerated by exposure to electromagnetic radiation in the spectrum of visible or ultraviolet light. ]
Oxidation-Reduction D010084 [A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). ]
Oxidative Coupling D058451 [The reaction of two molecular entities via oxidation usually catalyzed by a transition metal compound and involving dioxygen as the oxidant. ]
Oxidative Phosphorylation D010085 [Electron transfer through the cytochrome system liberating free energy which is transformed into high-energy phosphate bonds. ]
Oxidative Phosphorylation Coupling Factors D010086
Oxidative Stress D018384 [Excessive antioxidants potentially related to immune system and nutrient absorption disturbances. , A disturbance in the prooxidant-antioxidant balance in favor of the former, leading to potential damage. Indicators of oxidative stress include damaged DNA bases, protein oxidation products, and lipid peroxidation products (Sies, Oxidative Stress, 1991, pxv-xvi). ]
Oxides D010087 [Binary compounds of oxygen containing the anion O(2-). The anion combines with metals to form alkaline oxides and non-metals to form acidic oxides. ]
Oxidopamine D016627 [A neurotransmitter analogue that depletes noradrenergic stores in nerve endings and induces a reduction of dopamine levels in the brain. Its mechanism of action is related to the production of cytolytic free-radicals. ]
Oxidoreductases D010088 [The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9) ]
Oxidoreductases Acting on Aldehyde or Oxo Group Donors D050837 [A broad category of oxidoreductases that either reduce double bonds or oxidize single bonds between OXYGEN and CARBON in organic compounds. ]
Oxidoreductases Acting on CH-CH Group Donors D044925 [A subclass of enzymes which includes all dehydrogenases acting on carbon-carbon bonds. This enzyme group includes all the enzymes that introduce double bonds into substrates by direct dehydrogenation of carbon-carbon single bonds. ]
Oxidoreductases Acting on CH-NH Group Donors D000587 [Enzymes catalyzing the dehydrogenation of secondary amines, introducing a C=N double bond as the primary reaction. In some cases this is later hydrolyzed. ]
