Vitamin A compounds (principally as retinyl esters) are concentrated in Golgi apparatus fractions from rat liver. The amounts vary with the vitamin A status of the liver and show an inverse relation to the concentration of ubiubinone. The results suggest a specific role of the Golgi apparatus in the mobilization or action, or both, of vitamin A compounds.
