<prompt> Which receptors are present in liver for uptake of LDL?Apo EApo A and Apo EApo E and Apo B100Apo B 100  <response>: Classification of Lipoproteins - Depending on the density by ultra centrifugation or on the electrophoretic mobility, the lipoproteins in plasma are classified into five major types. Chylomicrons. Contains apoprotein B-48. Very low density lipoproteins VLDL or prebeta lipoproteins. Main apoprotein is B-100. Intermediate density lipoproteins IDL or broad-beta lipoproteins Low density lipoproteins LDL or betalipoproteins. Major apoprotein in LDL is B-100. High density lipoproteins HDL or alphalipoproteins. Major apoprotein in HDL is apo-A. Free fatty acids FFA or nonesterified fattyacids NEFA are complexed with albumin. FFAs are not generally included in the classification of lipoproteins, because they are loosely bound to the protein APOPROTEINS - Chylomicron - A,B-48,C-II,E VLDL - B-100, C-II,E IDL - B-100, E LDL- B-100 HDL - A-I, C, E FFA - Albumin.
