HDL stands for which lipoprotein?

• A. A1-lipoprotein (HDL)
• B. High-density lipoprotein (HDL)
• C. Low-density lipoprotein (LDL)
• D. Very-low-density lipoprotein (VLDL)

Answer: (B)

HDL is named for its density: it has more protein relative to lipid, giving it the highest density among the common lipoproteins. That’s why the correct label is High-density lipoprotein. The other options refer to different particles by their densities—low-density lipoprotein and very-low-density lipoprotein. The first option uses a nonstandard term that isn’t used to describe this lipoprotein, so it isn’t correct. For memory, think: HDL = high density, often thought of as the "good" cholesterol because it helps remove cholesterol from arteries.
