Is one of the five major groups of lipoproteins which enable cholesterol and triglycerides to be transported within the water based blood stream. HDL can remove cholesterol from atheroma within arteries and transport it back to the liver for excretion or re-utilization—which is the main reason why HDL-bound cholesterol is sometimes called “good cholesterol”, or HDL-C. A high level of HDL-C seems to protect against cardiovascular diseases. cf. LDL.
A fat and protein complex that removes excess cholesterol from arterial walls and transports it to the liver
HDL act as scavengers and pick up excess cholesterol and phospholipids from the tissues and return them to the liver for disposal. HDLs have earned the label “good cholesterol.”
High-density lipoproteins that return unused fat to the liver for disposal; HDL levels are raised by aerobic exercise; are beneficial due to their “removal” effect on harmful lipoproteins.
A lipoprotein in blood plasma composed primarily of protein and a minimum of cholesterol or triglyceride whose purpose is to transport cholesterol from the tissues to the liver.
Lipoproteins that can help move excess low-density lipoproteins (i.e., “bad” cholesterol, which can clog arteries) out of the human body by binding to the low-density lipoproteins (also known as LDL cholesterol) in the blood and then attaching to special LDL? receptor molecules in the liver. The liver then clears those (bound) low-density lipoproteins out of the body as a part of regular liver functions.
A molecular package consisting oi proteins and lipids that picks up cholesterol from the tissues and delivers it to the liver for reprocessing or excretion. Because it clears cholesterol out of the cardiovascular system, HDL has been called the “good” cholesterol. There are several types of HDL.
Protein-like structures that transport fats to the liver and lower the risk of cholesterol buildup in the arteries, thus lowering the risk of coronary heart disease.
A lipoprotein with a low percentage of cholesterol.
A protein-lipid complex responsible for the transport of lipids (triacylglycerides and cholesterol) in the blood from/to the liver to/from storage sites in the periphery. The complex is very dense and contains phospholipids as well as glycerides and sterols. Elevated HDL is associated with a reduction in risk for cardiovascular disease.
High density lipoproteins (HDLs) are lipid/protein complexes transported in the circulatory system. HDL particles are synthesized in the liver and to a lesser degree in the cells of the gastrointestinal tract. The primary role of HDL particles is the removal of cholesterol from lower density lipoproteins and tissues for transportation to the liver via the reverse cholesterol transport system.
Protein of plasma that contains relatively more protein and less fats; it serves to transport cholesterol and other lipids from plasma to tissues. According to some studies, high HDL levels are associated with lowered risks of cardiovascular disorders.
Plasma lipids bound to albumin, consisting of lipoproteins. They contain more protein than either very low-density lipoproteins or low-density lipoproteins. High density lipoprotein cholesterol is the so called good cholesterol; a high level is desirable.
High-density lipoprotein is considered to be the good form of cholesterol because of its dense structure. It cleans out plaque and debris (e.g., atherosclerotic buildup) from the blood vessel walls.
Carries cholesterol from the blood back to the liver, which processes the cholesterol for elimination from the body. It is often referred to as good cholesterol.
