Definition
Noun: A type of cholesterol carried in the blood by high-density lipoproteins (HDL). It is often called the "good" cholesterol because it helps remove other forms of cholesterol from the bloodstream, transporting them to the liver for processing and removal. A higher level of HDL cholesterol in the blood is associated with a lower risk of coronary artery disease.
