Question

Which of the following lipoproteins transports dietary triglycerides from intestine to tissues?

• A. VLDL
• B. LDL
• C. HDL
• D. Chylomicrons

Hint:

Chylomicrons carry dietary triglycerides from intestine to tissues.

Answer 1

The Correct Option is D

The question asks which lipoprotein is responsible for transporting dietary triglycerides from the intestine to tissues. Let's analyze the options:

1. Very-Low-Density Lipoprotein (VLDL): VLDL is primarily involved in the transport of triglycerides synthesized in the liver to peripheral tissues, not dietary triglycerides from the intestine.
2. Low-Density Lipoprotein (LDL): LDL is known for transporting cholesterol from the liver to tissues, but it is not involved in the transport of dietary triglycerides.
3. High-Density Lipoprotein (HDL): HDL is involved in reverse cholesterol transport, carrying cholesterol away from tissues to the liver, but it does not transport triglycerides from dietary sources.
4. Chylomicrons: Chylomicrons are the largest and least dense lipoproteins, responsible for the transport of dietary triglycerides and cholesterol from the intestines to tissues where they can be used or stored.

The correct answer is Chylomicrons because they are specifically designed to carry freshly absorbed dietary triglycerides from the intestine to other parts of the body.

Conclusion: Among the given options, Chylomicrons transport dietary triglycerides from the intestine to tissues. This makes chylomicrons essential for postprandial (after eating) lipid transport in the body.
