Which receptors are present in liver for uptake of LDL?
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.
