title: In vivo metabolism of esterified cholesterol and apoproteins in rabbit plasma low density lipoproteins.
abstract: Preparations of rabbit low density lipoproteins (LDL) labelled with 3H in the esterified and free cholesterol moieties and with 125I in the apoprotein moiety were injected intravenously into other rabbits. A substantial proportion of the esterified [3H]cholesterol removed from LDL during the first 30 min was recovered in the high density lipoprotein (HDL) fraction, while no such transfer of labelled apoprotein was observed. There was a clear cut differential in the decay of the different LDL components, slowest for the apoprotein, intermediate for esterified cholesterol and fastest for free cholesterol.
