Figure 2. Relative numbers of apoB particles.

Figure 2

LDL particles (on the right) are by far the most numerous, whereas chylomicron particles (the large particle on the left) are by far the least numerous. There are, on average, 9 times the number of VLDL particles as the sum of chylomicron and chylomicron particles in the postprandial period but 9 times the number of LDL particles as VLDL particles. Note VLDL and LDL particles can differ in size based on the relative amounts of triglycerides and cholesterol, respectively. LDL particles differ in the mass of cholesterol they contain, and therefore their size, resulting in the subclasses of LDL particles: LDL1, LDL2, and LDL3. In this figure, 1 chylomicron and 1 chylomicron remnant particle are combined, so that the proper relative number of apoB particles in the postprandial period can be illustrated. apoB indicates apolipoprotein B; LDL, low‐density lipoprotein; and VLDL, very low‐density lipoprotein.
