- What Makes HDL Cholesterol so Good? HDL is short for high-density lipoprotein. Each bit of HDL cholesterol is a microscopic blob that consists of a rim of lipoprotein surrounding a cholesterol center. The HDL cholesterol particle is dense compared to other types of cholesterol particles, so it's called high-density. Cholesterol isn't all bad.

Cholesterol Charts (What the Numbers Mean) Less than 200 mg/dL: desirable. 200-239 mg/dL: borderline high risk. 240 and over: high risk. HDL (high density lipoprotein) is considered the good cholesterol because it may help decrease the cholesterol buildup in the walls of arteries that causes narrowing of their openings.

- Realize that HDL is not cholesterol. Contrary to popular belief, HDL is not a type of cholesterol; rather, it's a type of cholesterol carrier or shuttle. There's only one type of cholesterol and it's essential to the body because it's needed to make all cell membranes and some hormones.

What is the difference between LDL and HDL cholesterol? LDL and HDL are very different lipoproteins. LDL is generally fatty acid rich with cholesterol ester (CE) core. Its density is low because it carried a lot of traiglycerides (TG) and so floats. It has a specific apolipoprotein marker which tells the body which lipoprotein it is.

- Low-density lipoprotein (LDL) is one of the five major groups of lipoproteins. These groups, from least dense to most dense, are: chylomicrons, very low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), LDL, and High Density Lipoprotein (HDL), all of them, particles far smaller than human cells. In nutrition, LDL is sometimes referred to as the bad cholesterol..

Low-density lipoprotein High-density lipoprotein. (Redirected from HDL cholesterol) High-density lipoproteins (HDL) are 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.

5.1.1: What Are LDL and HDL HDL is a type of cholesterol that stands for high density lipoprotein. This cholesterol is usually considered the good cholesterol. It is considered good because it takes cholesterol to the liver to be disposed of since cholesterol can't be dissolved in blood. HDL along with LDL are used to measure the risk of heart disease.

Unit 4 Biomed LDL - low-density lipoprotein (transports cholesterol to and from the cells), takes cholesterol to the cells from the liver; high levels can lead to buildup in the arteries and result in heart disease

VLDL test VLDL stands for very low density lipoprotein. Lipoproteins are made up of cholesterol, triglycerides, and proteins. They move cholesterol, triglycerides, and other lipids (fats) to around the body. VLDL is one of the three main types of lipoproteins. VLDL contains the highest amount of triglycerides. VLDL is a type of bad cholesterol because it helps cholesterol build up on the walls of arteries. A lab test is used to measure the amount of VLDL in your blood.

Lipid Panel Test HDL, or High-density Lipoprotein, transports cholesterol around the body and elevated levels have been correlated with fewer cardiovascular diseases. Elevated LDL, or Low-density Lipoprotein, levels can result in the formation or arterial plaques and increase the risk of cardiovascular disease.

- When it comes to HDL cholesterol -- good cholesterol – a higher number means lower risk. This is because HDL cholesterol protects against heart disease by taking the bad cholesterol out of your blood and keeping it from building up in your arteries. A statin can slightly increase your HDL, as can exercise.our total cholesterol level is in the Desirable range, but your level of bad LDL cholesterol is Very High. This may mean that your level of high-density lipoprotein (HDL), or good cholesterol, is too low.

- The higher the level of HDL cholesterol in your blood, the LOWER your chance is of getting heart disease. Coronary heart disease is a condition in which plaque (plak) builds up inside the coronary (heart) arteries. Plaque is made up of cholesterol, fat, calcium, and other substances found in the blood.When plaque builds up in the arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis). high LDL level leads to a buildup of cholesterol in your arteries. (Arteries are blood vessels that carry blood from your heart to your body.). HDL cholesterol sometimes is called “good” cholesterol. This is because it carries cholesterol from other parts of your body back to your liver.

What Does a Low HDL in the Blood Mean? Low HDL and Heart Disease. HDL carries 25 to 33 percent of total blood cholesterol. Other lipoproteins -- including LDL or bad cholesterol -- carry the balance of blood cholesterol. In contrast to the other lipoprotein carriers, HDL is often referred to as the good cholesterol carrier.

- The LDL/HDL ratio is actually a purer ratio than total cholesterol/HDL, because LDL is a measure of bad' cholesterol and HDL is a measure of good cholesterol, whereas the total cholesterol is the sum of HDL, LDL, and the VLDL.

lipoprotein LDL cholesterol: Low-density lipoprotein cholesterol, commonly referred to as 'bad' cholesterol. Elevated LDL levels are associated with an increased risk of heart disease. Lipoproteins, which are combinations of fats (lipids) and proteins, are the form in which lipids are transported in the blood. Low-density lipoproteins transport cholesterol from the liver to the tissues of the body. Search MedTerms:

High-Density Lipoprotein and Cardiovascular Risk HDL as an Independent Risk Factor for CAD. With few exceptions, low HDL is an independent risk factor for CAD in case-control and prospective observational studies. In contrast, high HDL levels are associated with longevity and are protective against the development of atherosclerotic disease.

How Do LDL and HDL Differ Structurally and Functionally? What Do Cholesterol Numbers Mean. Your total blood cholesterol is a measure of the cholesterol components LDL (low-density lipoprotein) cholesterol, HDL (high-density lipoprotein) cholesterol, and VLDL (very low-density lipoprotein, which is the triglyceride-carrying component of lipids).

- This could mean you have a high level of high-density lipoprotein, or good HDL cholesterol, which protects against heart disease. Or you could have elevated secondary lipids, such as non-HDL particles that increase the risk of heart disease. Your LDL level also could be optimal if you are taking a statin medication.

HDL cholesterol: How to boost your 'good' cholesterol HDL cholesterol: How to boost your 'good' cholesterol. Your cholesterol levels are an important measure of heart health. For HDL cholesterol, or good cholesterol, higher levels are better. High-density lipoprotein (HDL) is known as the good cholesterol because it helps remove other forms of cholesterol from your bloodstream. Higher levels of HDL cholesterol are associated with a lower risk of heart disease.

- HDL-C is considered to be beneficial, the so-called good cholesterol, because it removes excess cholesterol from tissues and carries it to the liver for disposal. As part of a lipid profile, HDL-C may also be used to monitor the effectiveness of treatment for unhealthy lipid levels.

What Does a Low LDL/HDL Ratio Mean? LDL and HDL are best thought of as cholesterol taxis. LDL is the “bad” taxi, because it transports cholesterol and fat from the liver into the bloodstream, where it can clog arteries. HDL is the “good” taxi, because it transports cholesterol from the blood back to the liver. As such, a low LDL-to-HDL ratio is a good thing, because it can reduce your risk of cardiovascular diseases.

- LDL stands for low-density lipoprotien cholesterol. It's typically considered bad cholesterol because it builds up on the walls of your arteries, thereby restricting the flow of blood to your heart and brain.

Familial HDL deficiency Familial HDL deficiency is a condition characterized by low levels of high-density lipoprotein (HDL) in the blood. HDL is a molecule that transports cholesterol and certain fats called phospholipids through the bloodstream from the body's tissues to the liver.
