Also Known As: Coenzyme q10, Co Q-10, Ubiquinone, Ubidecarenone, CoQ10, Q10
Coenzyme Q10, also known as ubiquinone, ubidecarenone, coenzyme Q, and abbreviated at times to CoQ10 /ËŒkoÊŠ ËŒkjuË ËˆtÉ›n/, CoQ, Q10, or Q, 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.
This oil-soluble, vitamin-like substance is present in most eukaryotic cells, primarily in the mitochondria. It 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 bodyâ€™s energy is generated this way. Therefore, those organs with the highest energy requirementsâ€”such as the heart, liver and kidney â€”have the highest CoQ10 concentrations. There are three redox states of coenzyme Q10: fully oxidized (ubiquinone), semiquinone (ubisemiquinone), and fully reduced (ubiquinol). The capacity of this molecule to exist in a completely oxidized form and a completely reduced form enables it to perform its functions in electron transport chain and as an antioxidant respectively.
