Definition of Semiquinone. Meaning of Semiquinone. Synonyms of Semiquinone

- Semiquinones (or ubisemiquinones, if their origin is ubiquinone) are free radicals resulting from the removal of one hydrogen atom with its electron during...
- exist in four redox states, which are the flavin-N(5)-oxide, quinone, semiquinone, and hydroquinone. FAD is converted between these states by accepting...
- neutral (semiquinone) state, and colourless when totally reduced. The oxidized and reduced forms are in fast equilibrium with the semiquinone (radical)...
- Doxorubicin, sold under the brand name Adriamycin among others, is a chemotherapy medication used to treat cancer. This includes breast cancer, bladder...
- three redox states, fully oxidized (ubiquinone), partially reduced (semiquinone or ubisemiquinone), and fully reduced (ubiquinol). The redox functions...
- protein' and to the bL heme. This oxidation reaction produces a transient semiquinone before complete oxidation to ubiquinone, which then leaves the Qo site...
- electron results in the free-radical (semiquinone) form of Q, and transfer of the second electron reduces the semiquinone form to the ubiquinol form, QH2....
- oxidoreductases induce reversible interconversions between the oxidized (FMN), semiquinone (FMNH•), and reduced (FMNH2) forms of the isoalloxazine core. FMN is...
- concentrations. There are three redox states of CoQ: fully oxidized (ubiquinone), semiquinone (ubisemiquinone), and fully reduced (ubiquinol). The capacity of this...
- convert to the semiquinone radical. At pH = 7, this conversion occurs at 100 mV:[citation needed] C6H4(OH)2 → C6H4(O)(OH) + ½ H2 The semiquinone radical can...
