Apolipoprotein B (apo B) exists in human plasma as two isoforms, apo B-48 and apo B-100. Apo B-100 is the major physiological ligand for the LDL receptor. It is a large monomeric protein , containing 4536 amino acid residues. Apo B-100 is synthesised in the liver and is required for the assembly of very low density lipoproteins (VLDL). It does not interchange between lipoprotein particles, as do the other lipoproteins, and it is found in IDL and LDL particles after the removal of the apolipoproteins A, apolipproteins E and apolipoproteins C. Apo B-48 is present in chylomicrons and chylomicron remnants and plays an essential role in the intestinal absorption of dietary fats. Apo B-48 is synthesised in the small intestine.
