Which lipoprotein primarily carries triglycerides from the liver to peripheral tissues?

• A. Triglycerides from the liver to peripheral tissues
• B. Cholesterol to the liver
• C. Glucose to the cells
• D. Cholesterol from tissues to the liver

Answer: (A)

Lipoproteins move lipids through the blood. The liver packages triglycerides into very-low-density lipoprotein (VLDL) and releases it to deliver these triglycerides to peripheral tissues. As the triglycerides are unloaded by lipoprotein lipase, VLDL is remodeled into IDL and then LDL, which mostly carries cholesterol to cells. HDL, in contrast, is involved in reverse cholesterol transport, taking cholesterol from tissues back to the liver. So the lipoprotein primarily responsible for carrying triglycerides from the liver to peripheral tissues is VLDL.
