Definition of ubiquinone in English:

ubiquinone

noun juːˈbɪkwɪnəʊnyo͞oˈbikwəˌnōn

Biochemistry

Any of a class of compounds which occur in all living cells and which act as electron-transfer agents in cell respiration. They are substituted quinones.
〔生化〕泛醌，辅酶Q
Example sentencesExamples
- Interactions of organic molecules such as dihydropyridines, ubiquinone, tryptophan, and halothane with lipid bilayers have been studied through molecular dynamics simulations.
- Strikingly, reaction centers appear to use that same solution not only for electrons but also for proton transfer toward their secondary ubiquinone acceptor site.
- The regulation of this biosynthetic pathway at the mitochondrial level depends on the ubiquinone, the alternative oxidase and a species-specific uncoupling protein.
- The succinate dehydrogenase complex (complex II) plays a role in both the tricarboxylic acid cycle and electron transfer to ubiquinone.
- Antioxidant compounds such as vitamins C and E, lipoic acid, ubiquinones, superoxide dismutase, catalase, and glucathione peroxidase can limit oxidative damage.

Origin

1950s: blend of ubiquitous and quinone.
