Cytochrome b5 reductase purified from liver plasma membrane reduces coenzyme Q (CoQ) in reconstituted liposomes in the absence of cytochrome b5. Both CoQ and its reductase are responsible for the reduction of the ascorbate free radical at the cell surface. Thus, NADH-CoQ reductase represents a partial reaction of NADH-AFR reductase in the plasma membrane. Cytochrome b5 reductase maintains CoQ and ascorbate in their reduced state to support antioxidations. Reduced CoQ prevents lipid peroxidation… CONTINUE READING
