ABSTRACT
Coenzyme Q is a fat-soluble component of electron transport chains and, in consequence, it tends to partition into lipophilic organelles of the body such as membranes, lipoproteins, and fat. The coenzyme content of the different organelles varies but the mechanism responsible for regulating the distribution of coenzyme Q is presently unknown. The primary role of coenzyme Q is to transfer electrons between redox components of electron transport chains and thereby to create proton gradients across membranes.
