[Interconversions of ubiquinone and ubichromenol in rat liver under the effect of alpha-tocopherol].
Incubation of ground liver preparation isolated from vitamin E-deficient rats resulted in correlated in time changes of ubiquinone and ubichromenol contents and their ration in tissues. A suggestion is made on the possibility of ubiquinone and ubichromenol interconversions and of the existence of a system controlling (depending on a functional state of the organism) a certain ratio of the quinones contents in animal tissues. Possible biochemical role of ubichromenol in animals is discussed.
