Apo E • Present in 3 isoforms • E2, E3, E4 • Is found in Chylomicrons and IDL that binds to a specific receptor on liver cell • It is essential for the normal catabolism of triglyceride-rich lipoprotien constituent • E2 binds poorly to receptors homozygous poor clearance of chylomicron remnants and IDL • E4 associated with increased susceptibility to late onset of Alzheimer's disease 27

The liver removes the chylomicron fragments, and the cholesterol is repackaged for transport in the blood in very low-density lipoproteins (VLDLs), which eventually turn into low-density lipoproteins (LDL).

Patients with abetalipoproteinemia develop severe vitamin E deficiency because they are defective in three steps in this pathway: First, along with other fat soluble vitamins, the fat malabsorption decreases the absorption of vitamin E Second, the small amount of vitamin E that maybe absorbed can not be efficiently secreted by the intestine because of the defect in the chylomicron secretion.
