serum very low density lipoprotein phospholipid level
Measurement of the amount of phospholipid, any of various phosphorus-containing lipids that are composed mainly of fatty acids, a phosphate group, and a simple organic molecule such as glycerol, carried in very low-density lipoprotein (VLDL) molecules in a specified volume of serum, the clear liquid that separates from blood after it has clotted completely, i.e. blood plasma from which fibrinogen has been removed. VLDL constitute a class of large (e.g. approximately 30-80 nm in diameter) lipoprotein particles, complex molecules that consist of a protein membrane surrounding a core of lipids. The VLDL class of lipoproteins has a density between 0.95 and 1.006 g/ml.
