Cholesterol esters - Study guides, Class notes & Summaries

What is a lipoprotein Many important molecules in the body are lipids. But transporting these molecules around the body through the blood presents an obvious problem, because, by definition, lipids are nonpolar and thus not very soluble in water. Small amounts of fatty acids are transported in the blood bound to blood proteins. These are called free fatty acids (despite the binding). Beyond this, however, other lipids are transported in special particles called lipoproteins. To emphasis, lip...

Atherosclerosis The abnormal accumulation of lipid deposits and fibrous tissue within the arterial walls and lumen, referred to as plaque or atheromas; CAD is the most prevalent and the leading cause of death in the US; CAD usually begins with HTN Plaque The buildup of deposits in the arteries r/t CAD; This causes blockages which reduce blood flow; The area of the artery affected cannot dilate because the wall is less elastic, which increases the risk of spasm, embolism, and thrombosis; When th...

Chylomicrons, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) are considered to be lipoproteins that transport lipids throughout the body; cholesterol is classified as a lipid. 2. In the laboratory procedure for the quantification of HDL, the purpose of the dextran sulfate is to: a. Precipitate all Apo A1 containing lipoproteins b. Covert cholesterol esters to choles...
