Types of Cholesterol

Lipoproteins and cholesterol--what is the connection?
Chylomicrons
What is the definition of a chylomicron? Chylomicrons are liporproteins that transport triglycerdies and cholesterol from the small intestine to other tissues for chylomicron metabolism.
An Explanation of the Major Lipoprotein Classes
This website gives you a broader picture of the different classes of lipoproteins that exist and what their functions are.
What Do Lipoproteins Do?
Lipoproteins are in charge of transporting cholesterol to various parts of the body.
The Connection Between Lipoproteins and Cholesterol
Lipoproteins play an intricate role in cholesterol transportation.
How Can I Raise My HDL Levels?
High density lipoproteins, or HDLs, are produced by the liver and carry cholesterol and other fats from tissues to the liver for recycling. HDLs are good for you -- the higher your HDL levels are, the better.
Intermediate Density Lipoprotein
Intermediate density lipoproteins, or IDLs, transport cholesterol and triglycerides through the body. IDLs are a type of cholesterol that are a product of vldl degradation and result in ldl cholesterol when broken down.
Lipoprotein (a)
Lipoprotein a is a type of cholesterol that consists of LDL cholesterol attached to apolipoprotein a. When lipoprotein a is high, you might be at an increased risk of heart disease.
Apolipoprotein E
Are you looking for the definition of apolipoprotein e? What is apo E? Apolipoprotein E is a protein that is found in triglycerides, chylomicrons, and HDL. High levels of Apo E can be correlated to high triglyceride levels. There may be apolipoprotein e testing for cardiovascular disease.
Apolipoprotein A1
Apolipoprotein a1 major protein that makes up high-density liporprotein, or HDL cholesterol. Having high levels of apo A1 could help in heart disease prevention.
Apolipoprotein B
Apo B is a major protein that makes up low-density liporprotein, or LDL cholesterol. Apo B helps transport cholesterol and triglycerides to cells in the body.
Oxidized Low Density Lipoprotein
An oxidized low density lipoprotein is a form of ldl that has been oxidized. Oxidized ldl can cause atherosclerosis by causing inflammation at the site of an artery and accumulation of fats within the artery.
How Can I Lower My LDL Cholesterol Level?
High LDL levels are an important risk factor for heart disease. LDL levels can be lowered by medication, but may also be lowered by exercise, smoking cessation, eating healthy, losing weight, and drinking alcohol. Lowering LDL levels will lower your risk of heart disease.
Is There A Bad Side To “Good” Cholesterol?
Having a high level of HDL cholesterol, or the "good" cholesterol, is a good thing, since it has a protective effect against heart disease and prevents cholesterol levels from accumulating in the blood. Researchers, however, are now finding out that HDL may have a bad side to it. They have discovered that the protein part on some of the HDL molecules may change over time, and may actually have the ability to cause heart disease.
Is Increasing HDL Levels the Answer to Cholesterol Problems?
You're familiar with the difference between "good" cholesterol (HDL) and "bad" cholesterol (LDL). Research has shown that high HDL levels can decrease your risk of heart disease. Despite this knowledge, there are no medications that specifically raise HDL cholesterol. This article addresses why raising HDL may not be enough.
What Are Triglycerides?
Triglycerides are the most common type of lipid found in the blood.
Triglyceride Levels and Stroke Risk
High lipids can place you at risk for having a heart attack, however there is another lipid that, if high enough, it can place your risk of having a stroke.
Very Low Density Lipoprotein
Very low density lipoproteins, or VLDL, are made up of triglycerides, cholesterol, and proteins. VLDL carries cholesterol from your liver to organs and tissues in the body. VLDL is a precursor to LDL.
C-Reactive Protein: A Cardiovascular Risk Factor?
C-reactive protein is not a lipid like cholesterol, but high levels of it could play an important role in causing heart disease when combined with high cholesterol.
Macrophage
Macrophages defend the body against foreign cells, like bacteria. They can also contribute to the formation of atherosclerosis, along with high cholesterol and high triglyceride levels.
