Ubiquinone is 2,3-dimethoxy-5-methyl-6-multiprenyl-1, 4-benzoquinone, also known as CoEnzyme Q (CoQ10, Q). The reduced form (QH2) is called ubiquinol and the partially reduced free-radical form is called semiquinone. The quinone group allows CoEnzyme Q to function as an electron-carrier, while the highly hydrophobic tail of isoprene units helps to confine CoEnzyme Q to lipid-rich areas of cells.
