in·ter·me·di·ate den·si·ty lip·o·pro·tein (IDL),
class of lipoproteins formed in degradation of very low density lipoproteins; about half are cleared quickly from the plasma into the liver by receptor-mediated endocytosis; the other half are degraded into low density lipoproteins.
intermediate density lipoproteinPhysiology A plasma lipoprotein with a density of 1.006-1.019 g/dl, formed by lipoprotein lipase hydrolysis of VLDL partially depleted of TGs Composition 15% protein, predominantly apoB and apoE, 25% phospholipid, 30% cholesterol, 30% TGs Role Transports cholesterol from intestine to liver; once in the liver, is delipidated by hepatic lipoprotein lipase to form a low-density protein
