Table II. Lipoprotein Composition.
Six month old mice were fasted for 4.5 hours. Serum five mice of each genotype was pooled and subjected to sequential ultracentrifugation to obtain VLDL, IDL, LDL and HDL. The amounts of triglyceride, total cholesterol, free cholesterol and phospholipids were determined for each fraction. The relative lipid composition, by weight, of each particle was calculated.
