Apo-AII is also a structural protein in HDL and acts as an activator of hepatic lipase. Watch an animation about atherosclerosis. Biochemistry, High Density Lipoprotein - StatPearls - NCBI Bookshelf Last Update: OctoApo-AI is the primary structural apolipoprotein of HDL and activates LecithinCholesterol AcylTransferase (LCAT). This is because it absorbs other types of cholesterol and carries them away from your arteries and back to your liver. They store excess energy from your diet.Ī high triglyceride level combined with high LDL (bad) cholesterol or low HDL (good) cholesterol is linked with fatty buildups within the artery walls, which increases the risk of heart attack and stroke. HDL (high-density lipoprotein) is often referred to as good cholesterol. ![]() Triglycerides are the most common type of fat in the body. The two most commonly known lipoproteins are low-density. This is because it absorbs other types of cholesterol and carries them away from. Cholesterol and other fats are carried in your bloodstream as spherical particles called lipoproteins. Only one-third to one-fourth of blood cholesterol is carried by HDL. HDL (high-density lipoprotein) is often referred to as good cholesterol. But HDL cholesterol doesn't completely eliminate LDL cholesterol. HDL carries LDL (bad) cholesterol away from the arteries and back to the liver, where the LDL is broken down and passed from the body. There are two main types of lipoprotein: high-density lipoprotein (HDL) cholesterol, which people may refer to as good cholesterol, and low-density lipoprotein (LDL), or bad, cholesterol. HDL cholesterol can be thought of as the “good” cholesterol because a healthy level may protect against heart attack and stroke. This narrows the arteries and increases the risk for heart attack, stroke and peripheral artery disease (PAD). LDL cholesterol is considered the “bad” cholesterol, because it contributes to fatty buildups in arteries ( atherosclerosis). A test measures the amount of each type of cholesterol in your blood. ![]() The other is high-density lipoprotein, or HDL. Two types of lipoproteins carry cholesterol to and from cells. The HDL cholesterol test measures the amount of cholesterol carried by HDL (high density lipoprotein) particles in the blood. HDL (high-density lipoprotein) is often referred to as good cholesterol.
