Quizplus · Accepted Answer

High-density lipoproteins (HDLs) contain less lipid and more protein in comparison to low-density lipoproteins (LDLs). HDLs are considered "good cholesterol" because they transport cholesterol away from the arteries and back to the liver for processing and removal from the body. LDLs, on the other hand, are known as "bad cholesterol" because they can accumulate in the walls of arteries, leading to atherosclerosis and potentially heart disease.
