High density lipoprotein (HDL) serves as the transit agent for cholesterol away from blood, tissues, and organs of the body to the liver, where cholesterol breakdown occurs. This process ultimately helps to remove cholesterol from the arteries. Colloquially known as the "good cholesterol", HDL makes up 20%-30% of the total cholesterol in the body.HDL is used in cardiovascular research and the development of potential therapeutic approaches to cardiovascular risk management.
