  • Title: In vitro catabolism of human very low density lipoproteins: fate of apoproteins B and C.
    Author: Catapano AL, Capurso A, Kinnunen PK.
    Journal: Artery; 1981; 9(2):87-95. PubMed ID: 7295047.
    Abstract:
    The fate of apo C-II, apo C-III and apo B during the in vitro catabolism of human very low density lipoproteins (VLDL) by the action of purified lipoprotein lipase was studied. Up to 58 percent of triglyceride apo C-II and C-III was released from VLDL during hydrolysis and at a similar rate. The amount of C apoproteins lost was proportional to triglyceride hydrolysis. The apo B content of VLDL remained constant. From these studies we conclude that during the hydrolysis of human VLDL, lipoprotein lipase, while including a net loss of apo C, is not responsible for major changes in the apo C-II/C-III ratio.
