Relationship between amounts of CoQ associated with membrane proteins and rate of superoxide anion radical generation by cardiac mitochondria of different mammalian species. Mitochondrial membrane proteins were isolated as deoxycholic acid (DOC) pelletable micelles, and the CoQ9 and CoQ10 content was determined by HPLC. The CoQ content (CoQ9 + CoQ10), retained in the mitochondrial DOC micelles in different species, is expressed as percent of the total amount of CoQ present in whole mitochondria and is plotted against the rate of O2˙̄ generation, reported previously by Lass et al., 1997.
