<prompt> Answer this question truthfullyWhat exactly is intermediate-density lipoprotein?  <response>: <reason> Intermediate density lipoproteins are a class of lipoproteins formed from the degradation of very low density lipoproteins, constituted essentially of triacylglycerols and cholesterol esters. They are cleared from the plasma into the liver by receptor-mediated endocytosis, or further degraded to form low density lipoproteins. They are usually 25 to 35 nm in diameter.v t e Lipids: lipoprotein metabolism General Chylomicron - HDL - LDL - IDL - VLDL - Lpa Apolipoproteins APOA 1, 2, 5 - APOB - APOC 1, 2, 3, 4 - APOD - APOE - APOH Other Lipoprotein lipase - Cholesterylester transfer protein Acetyl-CoA C-acyltransferase, LCAT - LDL receptor - Microsomal triglyceride transfer protein - ABCA1 - Lecithin-cholesterol acyltransferase see also disordersit:Lipoproteine a densità intermedia sv:Intermediate Density Lipoprotein Template:WikiDoc Sources Template:WH
