Incorporation of [3H]-cholecalciferol into the liver and the rate of its conversion into 25-OH-D are significantly larger after intravenous administration of this vitamin into liposomes than its dissolution in ethanol. The latter may be due to a different distribution of vitamin D3 in the cells of the liver. Incorporation of [3H]-vitamin D3 in reticulocytes suggests that its cells are a locus for storage of vitamin D, from which the latter is transported into hepatocytes where its 25-hydroxylation proceeds.
