Which lipoprotein contains mostly triglycerides?

Lipoprotein composition varies by what they carry. The liver ships triglycerides to tissues mainly in a particle designed for that purpose, which is VLDL. That makes VLDL the TG-rich lipoprotein among the options. As VLDL offloads triglycerides to muscles and adipose tissue, it becomes IDL and then LDL, shifting its content from triglycerides toward cholesterol esters. In contrast, HDL is richer in protein and cholesterol esters, and LDL carries more cholesterol than triglycerides. Apolipoprotein is a protein component of lipoproteins, not a distinct lipoprotein particle. Therefore, the lipoprotein containing mostly triglycerides is VLDL.
