Ubiquinone
Ubiquinone also known as coenzyme Q or simply CoQ, is a 1,4-benzoquinone, where Q refers to the quinone chemical group and 10 refers to the number of isoprenyl chemical subunits in its tail.
Structure[edit | edit source]
Ubiquinone is a fat-soluble substance resembling a vitamin. Its structure includes a quinone group, which is a ring of six carbon atoms with two oxygen atoms, and a tail of 10 isoprene units. The quinone group is responsible for the molecule's ability to accept and donate electrons.
Function[edit | edit source]
Ubiquinone is a vital participant in the electron transport chain, where it accepts electrons from complexes I and II. It then transfers these electrons to complex III, contributing to the formation of a proton gradient across the mitochondrial membrane. This gradient is used by ATP synthase to generate ATP, the main energy currency of the cell.
Role in human health[edit | edit source]
Ubiquinone has been studied for its potential role in treating various health conditions. It is a powerful antioxidant, protecting cells from damage by free radicals. It also plays a role in maintaining heart health, and some studies suggest it may help with neurological disorders.
Dietary sources[edit | edit source]
Ubiquinone is found in a variety of foods, including meat, fish, and whole grains. It can also be synthesized in the body.
