Coenzyme Q10

Coenzyme Q10 (CoQ10 /ˌkoʊkjuːˈtɛn/), also known as ubiquinone, is a naturally occurring <a href="/facts/Cofactor_(biochemistry)/AGo0PCUU">biochemical cofactor</a> (coenzyme) and an <a href="/facts/Antioxidant/4TG4MQ83">antioxidant</a> produced by the human body. It can also be obtained from dietary sources, such as meat, fish, seed oils, vegetables, and <a href="/facts/Dietary_supplement/SHXNNxaS">dietary supplements</a>. CoQ10 is found in many organisms, including animals and bacteria.
CoQ10 plays a role in <a href="/facts/Mitochondria/ErHqrdJ1">mitochondrial</a> <a href="/facts/Oxidative_phosphorylation/en2l08P9">oxidative phosphorylation</a>, aiding in the production of <a href="/facts/Adenosine_triphosphate/nB9bwgcU">adenosine triphosphate</a> (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 <a href="/facts/Isoprene/8ArKUyzT">isoprenyl</a> chemical subunits in its tail.
Although a ubiquitous molecule in human tissues, CoQ10 is not a dietary <a href="/facts/Nutrient/34bn4skK">nutrient</a> and does not have a <a href="/facts/Dietary_Reference_Intake/FWaI93Dm">recommended intake level</a>, and its use as a supplement is not <a href="/facts/Approved_drug/1AgqCVCh">approved</a> in the United States for any health or anti-disease effect.
