In the past several years the importance of lipoprotein lipase (LPL) as a multifunctional protein, involved in several different aspects of lipid and lipoprotein metabolism, has become evident. Thus, in addition to its traditional role in mediating the initial hydrolysis of circulating plasma triglycerides, recent studies implicate LPL in the binding of lipoproteins to cell surfaces and receptors, as well as indicating a potential role for LPL in the pathogenesis of atherosclerosis. Enhanced understanding of LPL structure, function and mechanism of action has provided insights into new potential pathways by which defects in LPL function may result in the development of different hyperlipidemic disorders and/or atherosclerosis.

UI	MeSH Term	Description	Entries
D006949	Hyperlipidemias	Conditions with excess LIPIDS in the blood.	Hyperlipemia,Hyperlipidemia,Lipemia,Lipidemia,Hyperlipemias,Lipemias,Lipidemias
D008071	Lipoprotein Lipase	An enzyme of the hydrolase class that catalyzes the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. The enzyme hydrolyzes triacylglycerols in chylomicrons, very-low-density lipoproteins, low-density lipoproteins, and diacylglycerols. It occurs on capillary endothelial surfaces, especially in mammary, muscle, and adipose tissue. Genetic deficiency of the enzyme causes familial hyperlipoproteinemia Type I. (Dorland, 27th ed) EC 3.1.1.34.

D008074	Lipoproteins	Lipid-protein complexes involved in the transportation and metabolism of lipids in the body. They are spherical particles consisting of a hydrophobic core of TRIGLYCERIDES and CHOLESTEROL ESTERS surrounded by a layer of hydrophilic free CHOLESTEROL; PHOSPHOLIPIDS; and APOLIPOPROTEINS. Lipoproteins are classified by their varying buoyant density and sizes.	Circulating Lipoproteins,Lipoprotein,Lipoproteins, Circulating
D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations

D001161	Arteriosclerosis	Thickening and loss of elasticity of the walls of ARTERIES of all sizes. There are many forms classified by the types of lesions and arteries involved, such as ATHEROSCLEROSIS with fatty lesions in the ARTERIAL INTIMA of medium and large muscular arteries.	Arterioscleroses
D014280	Triglycerides	An ester formed from GLYCEROL and three fatty acid groups.	Triacylglycerol,Triacylglycerols,Triglyceride
