The lipoprotein contains the greatest amount of protein is called?

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

Answer: (A)

Lipoproteins differ in how much protein versus lipid they carry, and density tracks with that balance: more protein makes a particle heavier and denser, while more lipid makes it lighter and less dense. The one with the greatest protein content is the high-density lipoprotein, HDL. It is the most dense and is known to have a higher protein-to-lipid ratio than the others. Chylomicrons are the least dense and are packed with triglycerides, LDL and VLDL have more lipid and less protein in comparison, so they contain less protein overall. That’s why HDL is the correct choice here.
