Definition:Measurement of the amount of cholesterol, a eukaryotic sterol that in higher animals is the precursor of bile acids and steroid hormones and a key constituent of cell membranes, carried in intermediate-density lipoprotein (IDL) molecules in a specified volume of blood, the fluid that circulates through the heart, arteries, capillaries and veins carrying nutrients and oxygen to the body tissues and metabolites away from them. IDL are relatively large lipoprotein particles (complex es that consist of protein surrounding a core of lipids) formed by degradation of very low density lipoproteins (VLDL) particles and thus having a size intermediate between those of VLDL and LDL. The IDL class of lipoproteins is defined as having a density between 1.006 and 1.019 g/ml.
Comment:Values for density ranges of the lipoprotein classes are approximate. The classes may be defined differently by different researchers, in part because class definitions depend on the number of subclasses into which the lipoprotein fractions are divided.
Synonyms:related_synonym: blood IDL level;   blood IDL-C level
