An isoprenoid quinone that enhances nonspecific resistance to bacterial infections. It stimulates phagocytosis in macrophages by modulation of the kinetics of the Fc receptor. It serves as an electron carrier from the flavoprotein to the cytochrome complex in reconstituted proteoliposomes where cytochrome O complex function as an efficient ubiquinol-8 oxidase.
CoQ8 has been used as a ligand to activate peroxisome proliferator-activated receptor (PPAR).
ChEBI: A ubiquinone whose structure comprises a 2,3-dimethoxy-5-methylbenzoquinone nucleus (common to all ubiquinones) and a side chain of eight isoprenoid units.
Coenzyme Q (CoQ) is a natural compound, which is broadly distributed in living organisms. It is a constituent of the electron transfer system. CoQ contains a benzoquinone moiety and an isoprenoid side chain.
