title: Essentiality of ubiquinone for choline oxidation in rat liver mitochondria.
abstract: Rat liver mitochondria treated extensively with n-pentane are incapable of oxidizing choline. Choline oxidation is more sensitive than is succinate oxidation to serial n-pentane extraction of mitochondria. The ability to oxidize choline is restored by the addition of ubiquinone-2 or ubiquinone-10 to the oxidase assay medium.
