What is an HDL lipoprotein?

High-density lipoprotein ( HDL) is one of the five major groups of lipoproteins. Lipoproteins are complex particles composed of multiple proteins which transport all fat molecules ( lipids) around the body within the water outside cells. They are typically composed of 80–100 proteins per particle (organized by one,...

Do níveis of high-density lipoprotein (HDL) cholesterol levels matter for cardiovascular health?

Níveis elevados de HDL costumam estar relacionados a menor risco cardiovascular; contudo, altos níveis de HDL colesterol decorrentes de algumas doenças genéticas podem não proteger de doença cardiovascular, provavelmente em razão das alterações metabólicas e lipídicas concomitantes.

What is the function of HDL-C?

HDL particles remove fats and cholesterol from cells, including within artery wall atheroma, and transport it back to the liver for excretion or re-utilization; thus the cholesterol carried within HDL particles (HDL-C) is sometimes called good cholesterol (despite being the same as cholesterol in LDL particles).

What are lipoproteins and what do they do?

Two types of lipoproteins carry cholesterol throughout the body: LDL (low-density lipoprotein), sometimes called “bad” cholesterol, makes up most of your body’s cholesterol. High levels of LDL cholesterol raise your risk for heart disease and stroke. HDL (high-density lipoprotein), or “good” cholesterol, absorbs cholesterol ...

What is the function of HDL cholesterol in the body?

HDL (high-density lipoprotein), or “good” cholesterol, absorbs cholesterol and carries it back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke. When your body has too much LDL cholesterol,...

What is the difference between lipoprotein and HDL?

Unlike the larger lipoprotein particles, which deliver fat molecules to cells, HDL particles remove fat molecules from cells. The lipids carried include cholesterol, phospholipids, and triglycerides, amounts of each are variable.

What is high-density lipoprotein (HDL)?

Also called: High-density lipoprotein. Cholesterol is a waxy, fat-like substance thats found in all the cells in your body. Your liver makes cholesterol, and it is also in some foods, such as meat and dairy products.

What is LDL and HDL in blood test?

LDL stands for low-density lipoproteins. It is sometimes called the bad cholesterol because a high LDL level leads to a buildup of cholesterol in your arteries. How do I know what my HDL level is? A blood test can measure your cholesterol levels, including HDL.

What is the function of HDL-C?

HDL particles remove fats and cholesterol from cells, including within artery wall atheroma, and transport it back to the liver for excretion or re-utilization; thus the cholesterol carried within HDL particles (HDL-C) is sometimes called good cholesterol (despite being the same as cholesterol in LDL particles).

What is the function of HDL and LDL particles?

HDL particles remove fats and cholesterol from cells, including within artery wall atheroma, and transport it back to the liver for excretion or re-utilization; thus the cholesterol carried within HDL particles (HDL-C) is sometimes called good cholesterol (despite being the same as cholesterol in LDL particles).

What is HDL cholesterol and why is it good?

HDL cholesterol is good because it helps move extra cholesterol through your body, keeping it from building up on artery walls. Ideally, you will have a balance, with lower levels of LDL cholesterol and higher levels of HDL cholesterol. Here are recommended levels of lipids in your blood measured in milligrams per deciliter (mg/dL). 2 

What is the role of HDL in the pathophysiology of atherosclerosis?

Several steps in the metabolism of HDL can participate in the transport of cholesterol from lipid-laden macrophages of atherosclerotic arteries, termed foam cells, to the liver for secretion into the bile. This pathway has been termed reverse cholesterol transport and is considered as the classical protective function of HDL toward atherosclerosis.

What Is a Lipoprotein? Cholesterol and triglycerides are fatty molecules. Because of their fat-like properties, they are not able to easily circulate in the bloodstream. In order for cholesterol and triglycerides to travel in the blood, they are often carried by proteins that make the cholesterol and triglycerides more soluble in blood.

How do lipoproteins affect cholesterol levels?
