| Abstract: | Lipolysis of human very low density lipoproteins (VLDL) by lipoprotein lipase (LPL) was inhibited in the presence of high density lipoproteins (HDL), anti-apolipoprotein (apo) CII, and by increasing the VLDL free cholesterol content but not with anti-apo CIII or lipoprotein-free plasma. The experiments lend direct evidence that the composition of VLDL and their milieu are important determinants of lipolysis by LPL. Apo CIII may not be critical in LPL mediated VLDL catabolism. |
