CoQ10, also known as coenzyme Q10 or ubiquinone, is a quinone that is naturally present in the majority of aerobic organisms ranging from bacteria to mammals. It was first discovered in 1940 and isolated from bovine heart mitochondria in 1957[1]. In the human body, CoQ10 is found at the highest levels in the heart, liver, kidneys and pancreas. It is mainly involved in aerobic cellular respiration and is very important in the energy metabolism of the mitochondrial electron transport respiratory chain. Considering its important function, the level of CoQ10 in the body, especially in certain organs, may be reduced under certain physiological or disease conditions.
