One molecule of apo B₄₈ encircles each chylomicron and chylomicron remnant particle. The chylomicron remnant particle contains less TG but the same amount of cholesterol as the intact chylomicron particle. The difference in TG mass represents the mass of TG delivered to adipose tissue and skeletal muscle. One molecule of apo B₁₀₀ encircles VLDL, LDL, and Lp(a) particles. Lp(a) particles are an LDL particle to which a molecule of apo(a) has been attached. One molecule of apo B₄₈ encircles a chylomicron or chylomicron remnant particle. apoB indicates apolipoprotein B; CE, cholesteryl ester; LDL, low‐density lipoprotein; Lp(a), lipoprotein(a); TG, triglycerides; and VLDL, very low‐density lipoprotein.
