Among lipoproteins, which carries the most triglycerides?

• A. CM
• B. VLDL
• C. LDL
• D. HDL

Answer: (A)

The main idea here is that chylomicrons are the triglyceride-rich lipoproteins. They are formed in the intestinal lining from fats absorbed after a meal and travel through the bloodstream carrying a large load of triglycerides to tissues like muscle and adipose tissue. In capillaries, lipoprotein lipase acts on these triglycerides, releasing fatty acids for use or storage, which is why chylomicrons are so loaded with TG after a meal. What’s left after TG removal are chylomicron remnants, which are taken up by the liver.

In comparison, lipoprotein particles from the liver (VLDL) also carry triglycerides but to a lesser extent than chylomicrons, because their main role includes distributing endogenously synthesized triglycerides. LDL and HDL carry relatively little triglyceride; LDL is richer in cholesterol esters, and HDL is primarily involved in reverse cholesterol transport with low triglyceride content.

So, the lipoprotein carrying the most triglycerides is the intestinally derived chylomicron.
