Which type of lipoproteins is primarily responsible for getting rid of excess cholesterol?

• A. Very low-density lipoproteins
• B. Low-density lipoproteins
• C. High-density lipoproteins
• D. Chylomicrons

Answer: (C)

High-density lipoproteins (HDL) are known as "good" cholesterol because their primary function is to transport excess cholesterol away from the arteries and back to the liver. In the liver, cholesterol can be metabolized and eliminated from the body, playing a crucial role in maintaining healthy cholesterol levels and reducing the risk of cardiovascular diseases. The ability of HDL to remove cholesterol from the bloodstream helps prevent the buildup of plaque in the arteries, which can lead to atherosclerosis and other heart-related issues. In contrast, other types of lipoproteins like very low-density lipoproteins (VLDL) and low-density lipoproteins (LDL) are primarily involved in delivering cholesterol to tissues, which can contribute to cardiovascular problems if present in excess. Chylomicrons are mainly responsible for transporting dietary lipids from the intestines to other locations in the body. Thus, HDL is specifically designed for the removal and recycling of cholesterol, making it the correct answer in this context.
