Coenzyme Q10 (also known as ubiquinone, ubidecarenone, coenzyme Q, and abbreviated at times to CoQ10 – pronounced like "ko-cue-ten" –, CoQ, Q10, or simply Q) is a 1,4-benzoquinone, where Q refers to the quinone chemical group, and 10 refers to the number of isoprenyl chemical subunits.
This oil-soluble substance is present in most eukaryotic cells, primarily in the mitochondria. Recent studies have found evidence of mitochondrial dysfunction in autism. This is why Coenzyme Q10 is often part of the supplement regimen given to special needs children.
CoQ10 is a component of the electron transport chain and participates in aerobic cellular respiration, generating energy in the form of ATP. Ninety-five percent of the human body’s energy is generated this way. Therefore, those organs with the highest energy requirements—such as the heart and the liver—have the highest CoQ10 concentrations.
