Cooenzyme Q10 (CoQ10) is a component of the electron transport chain and participates in aerobic cellular respiration, generating energy in the form of ATP. CoQ1 is an amphipathic CoQ10 homolog that has a tail consisting of five isoprene units. It has been used as an electron acceptor to study a range of oxidoreductases as isolated enzymes, in subcellular fractions, in intact cells in culture, and in perfused organs. Ubiquinone analogs, including CoQ1, impact mitochondrial permeability transition pore (PTP) formation, as well as PTP-dependent cell death, in an analog- and cell-specific manner.
