ubidecarenone

Coenzyme Q10 powder Coenzyme Q (CoQ /ˌkoʊkjuː/), also known as ubiquinone, is a naturally occurring biochemical cofactor (coenzyme) and an antioxidant produced by the human body. The human body mainly produces the form known as coenzyme Q10 (CoQ10, ubidecarenone), but other forms exist. CoQ is used by and found in many organisms, including animals and bacteria. As a result, it can also be obtained from dietary sources, such as meat, fish, seed oils, vegetables, and dietary supplements.

CoQ plays a role in mitochondrial oxidative phosphorylation, aiding in the production of adenosine triphosphate (ATP), which is involved in energy transfer within cells. The structure of CoQ10 consists of a benzoquinone moiety and an isoprenoid side chain, with the "10" referring to the number of isoprenyl chemical subunits in its tail.
