low-density lipoprotein (LDL), a plasma protein provided from very low–density lipoproteins (VLDLs) or by the liver, containing relatively more cholesterol and triglycerides than protein. It is derived in part, if not completely, from the intravascular breakdown of the very low–density lipoproteins and delivers lipids and cholesterol to the body tissues. The high cholesterol content may account for its greater atherogenic potential as compared with the VLDLs.
