Which lipoprotein is commonly referred to as good cholesterol?

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

Answer: (C)

HDL is the lipoprotein commonly called good cholesterol because it helps remove cholesterol from arteries and other tissues and transports it to the liver for disposal. This reverse cholesterol transport reduces cholesterol buildup in arterial walls, lowering cardiovascular risk. HDL particles are small, dense, and rich in apolipoprotein A-I, which supports cholesterol efflux from cells such as macrophages in plaques. In contrast, LDL delivers cholesterol to tissues and promotes plaque formation, while VLDL and chylomicrons mainly carry triglycerides. So HDL’s role in cleaning up cholesterol explains why it’s considered the beneficial type.
