Coensyme Q10 (CoQ10), also know as ubiquinone or ubidecarenone, is present in all tissues and membranes in different amounts. The “Q10” refers to the 10 isoprene units (5 carbons each) that are attached to the quinone ring.

Coenzyme Q10 is both a vital cell membrane antioxidant as well as an important component of the electron transport chain. As a fat soluble compound, CoQ10 is best absorbed in the presence of dietary lipids.
