What Is The Difference Between Hdl And Ldl
Good vs. bad: Hdl is the 'healthy' cholesterol that 'cleans' the blood vessels of 'blockages' (plaques). Ldl is the 'lousy' cholesterol that is the main component of the arterial plaques. One would want a very high HDL (above 50 mg/dl for women) and a very low LDL (close to 60-70 mg/dl). ...Read moreSee 1 more doctor answer
HDL, or high density lipoprotein, is a molecule in the body that is responsible for the transport of lipids (fats) from various organs including blood vessels back to the liver for processing and possible elimination. Because it helps prevent accumulation of lipids in blood vessels, HDL cholesterol is ...Read more
Directional: Total serum cholesterol is made up of several component lipoproteins. Amongst these are fractions: hdl-c is the "good", which you want to be as high as possible and ldl-c is the "bad" which you want to be as low as possible. Lifestyle and, if needed, drug therapy, can help towards those goals. ...Read moreSee 1 more doctor answer

Cholesterol: High-density lipoprotein is known as "good" cholesterol. Low-density lipoprotein is known as "bad" cholesterol. Thought that HDL tends to carry cholesterol away from the arteries and back to the liver, where it's passed from the body. Ldl can slowly build up in the inner walls of the arteries that supply the heart and brain, with other substances, it can form plaque (thick & hard) in the arteries. ...Read moreSee 1 more doctor answer
A measure: Cholesterol (c) is actually transported through the blood as a constiuent of lipoproteins. These are associated with atherosclerosis; ldl-low density liporoteins-causing and hdl-high density lipoproteins-protecting against. When c l is fractionated and measured the LDL cholesterol correlates to the amount of LDL and the HDL cholesterol correlates to the hdl. Thus c provides an indirect measure. ...Read moreSee 1 more doctor answer
Chemical and fuel: Cholesterol is a chemical made by the body as well taken in food and is essential for many body functions, high levels are associated with heart disease. Calorie is a measure of the fuel or energy in food. A gram of carbohydrate or protein has 4 calories and a gram of fat has 9 calories, one gram of alcohol has 7 calories. ...Read more
Particle vs. protein: Hi. Chylomicrons are a class of lipoprotein particles that are produced by the intestines to mobilize and transport non-water soluble dietary lipids (from food) via the thoracic duct into the blood, and from there, deliver fats to tissues and the remnant to the liver. There are many different apolipoproteins that serve structural & metabolic roles for various lipoproteins (chylos, VLDL, LDL, HDL) ...Read more
HDL is Good: Hdl or high density lipoprotein and LDL or low density lipoprotein are particles that are important in cholesterol metabolism. Hdl is the "good" particle that pulls cholesterol out of the arterial wall. Ldl is the "bad" particle particularly when it is "dense" or cholesterol laden that allow cholesterol transportation and deposition into the artery wall accelerating atherosclerosis. ...Read moreSee 1 more doctor answer
Polarity: Hi. Phospholipids (PLs) are polar, amphipathic molecules: part of the molecule loves a water environment and the other part loves an oily (non-water) environment. PLs are the main lipid component of cell membranes and the coats of lipoproteins. Triglycerides (fats, like butter, oils, lard) are hydrophobic and not soluble in water. PLs help create a hydrophobic environment for non-water soluble lip ...Read more
High Cholesterol and: Triglcerides, either as an intrinsic genetic malady or diet and diabetes, lead to plaque, and then manifestations of atherosclerosis, including coronary artery disease. Treatmnt of chol/tg elevation reduces mortality and risk of coronary stenosis, and maybe other vascular events (stroke, aortic aneurysm, peripheral vascular disease). ...Read moreSee 1 more doctor answer
Cause and effect: Atherosclerosis is a process where plaque builds up in arteries due to a variety of factors. When the plaque build up is extensive enough it can restrict blood flow and cause ischemia. Ischemia, which occurs when blood flow is not sufficient to meet the need for blood may result from extensive atherosclerosis. however it is important to note that atherosclerosis usually does not result in ischemia ...Read more
