cholesterol which is contained in or bound to very low density lipoproteins (VLDL). High circulating levels of VLDL cholesterol are found in HYPERLIPOPROTEINEMIA TYPE IIB. The cholesterol on the VLDL is eventually delivered by LOW-DENSITY lipoproteins to the tissues after the catabolism of VLDL to INTERMEDIATE-DENSITY lipoproteins, then to LDL.
