During the formation of chylomicrons, the first portion that is formed is the pre-chylomicron or the primordial chylomicron, which is composed of phospholipids, cholesterol, small amounts of triglycerides, and a special lipoprotein known as apolipoprotein B48 (apoB48).

WebChylomicrons are the largest and most buoyant class of lipoprotein. The major protein component is apo B-48 but they also contain apo A-I, apo A-II and apo A-IV. After secretion, they acquire apo E and apo C from HDL. Chylomicrons are formed in the intestine and are the transport vehicle for dietary fat. WebChylomicrons are formed in the ER lumen by a two-step process. In the first step, apolipoprotein B-48 (apoB-48), which is only 48% of the translated full-length apoB transcript, is pulled across the ER membrane through its translocon by the microsomal triacylglycerol transport protein (MTP).
