Two of these are familiar today: the low-density lipoproteins, known as LDL, the bad cholesterol, and the high-density variety, known as HDL, the good cholesterol. (This is an oversimplification, as I will explain shortly.) The third class is known as VLDL, which stands for “very low-density lipoproteins,” and these play a critical role in heart disease. Most of the triglycerides in the blood are carried in VLDL; much of the cholesterol is found in LDL. That LDL and HDL are the two species of lipoproteins that physicians now measure when we get a checkup is a result of the oversimplification of the science, not the physiological importance of the particles themselves.
