| lipoprotein | <biochemistry> An important class of serum proteins in which a spherical hydrophobic core of triglycerides or cholesterol esters surrounded by an amphipathic monolayer of phospholipids, cholesterol and apolipoproteins. Classified according to density: chylomicrons, large low density particles, very low density, low density and high density species. Important in lipid transport, especially cholesterol transport in the blood stream. Abnormalities in lipoprotein metabolism have been implicated in certain heart diseases. (13 Nov 1997) |
|---|---|
| lipoprotein electrophoresis | Electrophoretic separation of plasma lipoproteins. (05 Mar 2000) |
| lipoprotein lipase | <enzyme> An enzyme of the hydrolase class that catalyses 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 hyperlipoproteinaemia type I. Chemical name: Triacylglycero-protein acylhydrolase Registry number: EC 3.1.1.34 (12 Dec 1998) |
| lipoprotein lipase deficiency, familial | A rare familial condition characterised by massive chylomicronaemia and decreased levels of other lipoproteins. It is due to deficiency of lipoprotein lipase, an alkaline triglyceride hydrolase which catalyses an important step in the extrahepatic removal of triglyceride-rich lipoproteins from the blood. (12 Dec 1998) |
| lipoprotein Lp(a) | A lipoprotein composed of an LDL particle combined with an additional protein, Lp(a) specific protein; elevated levels have been identified as a risk factor for coronary artery disease. (05 Mar 2000) |
| lipoprotein polymorphism | Heritable variations in low density beta-lipoproteins; the variant lipoproteins exhibit different antigenic and chemical properties when compared with normal lipoproteins. (05 Mar 2000) |
| lipoprotein(a) | A family of lipoprotein particles varying in density and size depending on the protein-lipid ratio and the protein composition. These particles consist of apolipoprotein b-100 covalently linked to apolipoprotein-a by one or two disulfide bonds. There is a correlation between high plasma levels of this lipoprotein and increased risk for atherosclerotic cardiovascular disease. (12 Dec 1998) |
| lipoprotein(a) hyperlipoproteinaemia | Elevated levels of lipoprotein(a) in the serum; associated with an increased risk of coronary disease. (05 Mar 2000) |
| lipoprotein-associated coagulation inhibitor | Formerly known as anticonvertin; a protein that inhibits the extrinsic pathway of coagulation by binding to the tissue factor III-factor VII-Calcium-factor Xa complex. (05 Mar 2000) |
| lipoprotein-x | An abnormal lipoprotein which is present in large amounts in individuals suffering from obstructive liver diseases. It exists as a bilayer vesicle of equimolar phospholipids and unesterified cholesterol containing small amounts of plasma proteins (mainly albumin) in its internal aqueous compartment together with some apolipoproteins adsorbed on its surface. Separates with ldl by ultracentrifugation. (12 Dec 1998) |
| lipoproteins | Any of the lipid-protein complexes in which lipids are transported in the blood. Lipoprotein particles consist of a spherical hydrophobic core of triglycerides or cholesteryl esters surrounded by an amphipathic monolayer of phospholipids, cholesterol, and apolipoproteins. (12 Dec 1998) |
| lipoproteins, hdl | A class of lipoproteins frequently divided into hdl2 and hdl3 and the minor variant hdl1. Hdl promote transport of cholesterol from extrahepatic tissue to the liver for excretion in the bile. Synthesised by the liver as discoid "nascent hdl" particles lacking a lipid core, they accumulate a core of cholesterol esters during reverse cholesterol transport and transfer them to the liver directly or indirectly via other lipoproteins. Hdl also shuttle apolipoproteins c-II and e to and from triglyceride-rich lipoproteins during catabolism of the lipoproteins. Serum hdl cholesterol has been negatively correlated with premature coronary heart disease. (12 Dec 1998) |
| lipoproteins, hdl cholesterol | Cholesterol which is contained in or bound to high density lipoproteins (hdl). High density lipoproteins transport cholesterol from peripheral tissues to the liver thereby acting as a scavenger to prevent excess accumulation and deposition of cholesterol in blood vessels. (12 Dec 1998) |
| lipoproteins, ldl | A class of lipoproteins responsible for transport of cholesterol to extrahepatic tissues. They are formed in the circulation when very-low-density lipoproteins are degraded first to intermediate-density lipoproteins and then to ldl by the gain and loss of specific apolipoproteins and the loss of most of their triglycerides. Ldl are taken up and catabolised by both the liver and extrahepatic tissues by specific receptor-mediated endocytosis. (12 Dec 1998) |
| lipoproteins, ldl cholesterol | Cholesterol which is contained in or bound to low density lipoproteins (ldl). Ldl transport cholesterol to peripheral tissues and regulate de novo cholesterol synthesis at these sites. Atherosclerosis is caused by the deposit of cholesterol on the walls of blood vessels, because of high concentrations of ldl cholesterol in plasma. (12 Dec 1998) |
| a1-lipoprotein | A lipoprotein fraction of relatively low molecular weight, high density, rich in phospholipids, and found in the a1-globulin fraction of human plasma. (05 Mar 2000) |
|---|---|
| b1-lipoprotein | A lipoprotein fraction of relatively high molecular weight, low density, rich in cholesterol, and found in the beta-globulin fraction of human plasma. (05 Mar 2000) |
| receptors, lipoprotein | Cell surface proteins that bind lipoproteins with high affinity. Lipoprotein receptors in the liver and peripheral tissues mediate the regulation of plasma and cellular cholesterol metabolism and concentration. The receptors generally recognise the apolipoproteins of the lipoprotein complex, and binding is often a trigger for endocytosis. (12 Dec 1998) |
| very low density lipoprotein | <biochemistry> A lipoprotein substances (combination of a fat and a protein) which acts as a carrier for cholesterol and fats (particularly triglycerides) in the bloodstream. Elevations in very low density lipoprotein in the bloodstream are associated with an increased risk of atherosclerosis and coronary artery disease. Acronym: VLDL (18 Nov 1997) |
| multiple lipoprotein-type hyperlipidaemia | <biochemistry> Inherited as a defective gene, this disorder is characterised by elevations in serum cholesterol and/or triglycerides. There are often multiple types of lipoproteins (LDL) elevated in one family. This condition is associated with an increased risk of cardiovascular disease. Origin: Gr. Haima = blood (27 Sep 1997) |
| high density lipoprotein | <biochemistry> These lipoproteins acts to carry cholesterol in the bloodstream. Raised high density lipoprotein levels have been correlated with a lower risk for heart disease. Less than 35 mg/dl is considered a positive risk factor for coronary artery disease, over 60 mg/dl is considered a negative risk factor (reduces your risk of heart disease). Recent studies show a low high density lipoprotein level is the strongest predictor of cardiovascular death in women. Acronym: HDL (18 Nov 1997) |
| intermediate density lipoprotein | Class of lipoproteins formed in degradation of very-low-density lipoproteins; about half are cleared quickly from the plasma into the liver by receptor-mediated endocytosis; the other half are degraded into low density lipoproteins. (05 Mar 2000) |
| familial high density lipoprotein deficiency | Familial high {density lipoprotein deficiency}; a heritable disorder of lipid metabolism characterised by almost complete absence from plasma of high density lipoproteins, and by storage of cholesterol esters in foam cells, tonsillar enlargement, an orange or yellow-gray colour of the pharyngeal and rectal mucosa, hepatosplenomegaly, lymph node enlargement, corneal opacity, and peripheral neuropathy; autosomal recessive inheritance. Synonym: familial high {density lipoprotein deficiency}, Tangier disease. Origin: G. An-, priv., + alpha, a, + lipoprotein + -aemia, blood (05 Mar 2000) |
| familial lipoprotein lipase deficiency | An rare inherited disorder where there is a deficiency of an enzyme (lipoprotein lipase) which breaks down fat molecules, causing the accumulation of fats or lipoproteins in the blood. Symptoms in infancy include abdominal pain (appears as if its colic), failure to thrive and skin lesions (xanthomas). (27 Sep 1997) |
| familial lipoprotein lipase inhibitor | An inhibitor found in certain individuals that inhibits lipoprotein lipase resulting in accumulation of chylomicrons, VLDL, and triacylglycerols; similar in symptoms to familial lipoprotein lipase deficiency. (05 Mar 2000) |
| low density lipoprotein | <biochemistry> A lipoprotein substances (combination of a fat and a protein) which acts as a carrier for cholesterol and fats in the bloodstream. High levels of low density lipoprotein are considered a positive risk factor for the development of coronary artery disease. Less than 130 mg/dl is desirable, 130 to 159 mg/dl is borderline high, over 160 is considered high. Acronym: LDL (10 Jan 1998) |
| low density lipoprotein receptor | <biochemistry> A cell surface protein that mediates the endocytosis of low density lipoprotein by cells. Genetic defects in low density lipoprotein receptors lead to abnormal serum levels of low density lipoprotein and hypercholesterolaemia. (16 Mar 1998) |
| low-density lipoprotein receptors | Receptors on the surface of cells, especially liver cells, which bind to low density lipoprotein and promote clearance of LDL from the plasma. (05 Mar 2000) |
