Common Name | Ubiquinone 6 |

Description | Ubiquinone 6, also known as coenzyme Q6 or coq-6, belongs to the class of organic compounds known as ubiquinones. These are coenzyme Q derivatives containing a 5, 6-dimethoxy-3-methyl(1,4-benzoquinone) moiety to which an isoprenyl group is attached at ring position 2(or 6). Ubiquionone 10 (CoQ10) is involved in cellular respiration. Ubiquinone 6 is an extremely weak basic (essentially neutral) compound (based on its pKa). It is an endogenouse compound but it has also been isolated from foods containing baker's yeast. Ubiquione-6 has just 6 isoprene units. In humans, ubiquinone 6 is involved in ubiquinone biosynthesis. Ubiquinone 6 is a member of the chemical class known as Polyprenylbenzoquinones. It is fat-soluble and is therefore mobile in cellular membranes; it plays a unique role in the electron transport chain (ETC). These are compounds containing a polyisoprene chain attached to a quinone at the second ring position. In the inner bacterial membrane, electrons from NADH and succinate pass through the ETC to the oxygen, which is then reduced to water. The transfer of electrons through ETC results in the pumping of H+ across the membrane creating a proton gradient across the membrane, which is used by ATP synthase (located on the membrane) to generate ATP. Ubiquinone 6 is an intermediate in the synthesis of Ubiquionone 10. Normally in humans it has 10. |
