LDL is responsible for carrying cholesterol to cells that need it. Elevated LDL levels are associated with an increased risk of cardiovascular disease.

What is the function of LDL and HDL?

HDL helps rid your body of excess cholesterol so it’s less likely to end up in your arteries. LDL is called “bad cholesterol” because it takes cholesterol to your arteries, where it may collect in artery walls. Too much cholesterol in your arteries may lead to a buildup of plaque known as atherosclerosis.

HDL (high density lipoprotein) cholesterol is known as “good” cholesterol. HDL takes the “bad,” LDL (low density lipoprotein) cholesterol out of your blood and keeps it from building up in your arteries.
