 (lĭp′ō-prō′tēn′, -tē-ĭn, lī′pō-)
Any of a group of conjugated proteins in which at least one of the components is a lipid. Lipoproteins, classified according to their densities and chemical qualities, are the principal means by which lipids are transported in the blood.


(ˌlɪpəʊˈprəʊtiːn; ˌlaɪ-)
(Biochemistry) any of a group of proteins to which a lipid molecule is attached, important in the transport of lipids in the bloodstream. They exist in two main forms: high-density lipoproteins and low-density lipoproteins. See also low-density lipoprotein


(ˌlɪp əˈproʊ tin, -ti ɪn, ˌlaɪ pə-)

any of the class of proteins that contain a lipid combined with a simple protein.


(ˌlɪp əˌproʊ tinˈæ, -ti ɪnˈeɪ, ˌlaɪ pə-)
a plasma lipoprotein containing protein and cholesterol, high levels of which are associated with atherosclerosis.
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.lipoprotein - a conjugated protein having a lipid component; the principal means for transporting lipids in the blood
compound protein, conjugated protein - a protein complex combining amino acids with other substances
alpha-lipoprotein, HDL, high-density lipoprotein - a lipoprotein that transports cholesterol in the blood; composed of a high proportion of protein and relatively little cholesterol; high levels are thought to be associated with decreased risk of coronary heart disease and atherosclerosis
beta-lipoprotein, LDL, low-density lipoprotein - a lipoprotein that transports cholesterol in the blood; composed of moderate amount of protein and a large amount of cholesterol; high levels are thought to be associated with increased risk of coronary heart disease and atherosclerosis
very low density lipoprotein, VLDL - large lipoproteins rich in triglycerides; VLDLs circulate through the blood giving up their triglycerides to fat and muscle tissue until the VLDL remnants are modified and converted into LDL


n lipoproteína; high density — (HDL) lipoproteína de alta densidad; low density — (LDL) lipoproteína de baja densidad; very low density — (VLDL) lipoproteína de muy baja densidad

There are five major lipoproteins in blood: chylomicrons; very-low-density lipoprotein (VLDL); intermediate-density lipoprotein (IDL); low-density lipoprotein (LDL); and high-density lipoprotein (HDL).
This modeling is rooted in the classical definition of LDL by the Friedewald equation(6) and p quantification, which is inclusive of intermediate-density lipoprotein and lipoprotein(a).
Non-high-density lipoprotein (Non-HDL) cholesterol has been shown to be superior predictor of cardiovascular risk,1 because it contains cholesterol of all atherogenic particles, including low density lipoprotein (LDL), Lipoprotein A, very-low-density lipoprotein (VLDL),VLDL remnant and intermediate-density lipoprotein.
Non-HDL is a novel idea that is an estimate of cholesterol content in the atherogenic lipoproteins, including intermediate-density lipoprotein (IDL), very low density lipoprotein (VLDL), LDL, and lipoprotein cholesterol Lp(a).
SBo induced a decreasing trend in the serum total, intermediate-density lipoprotein (IDL) and low-density lipoprotein (LDL) cholesterol, and subfractions of IDL and LDL in group B.
As is known, when the Friedewald formula was used, LDL-C molecules include intermediate-density lipoprotein (2).
The formula: Total Cholesterol = VLDL-Cholesterol + LDL-Cholesterol + HDL-Cholesterol, is generally accepted as a convenient approximation, because the LDL fraction is heterogenous and contains intermediate-density lipoprotein (IDL), with a density of 1.
The remnants of CM and VLDL, after LPL has hydrolysed triglycerides, are smaller and denser and eventually enter the intermediate-density lipoprotein (IDL) category.
A physiologic elevation of LDL cholesterol occurs with both omega-3 fatty acids and fibrates as lipoprotein lipase metabolizes VLDL particles secreted by the liver, removing triglycerides, shrinking the molecule into intermediate-density lipoprotein (IDL) and low density lipoprotein (LDL).
Because particles of LDL, intermediate-density lipoprotein (IDL) and VLDL each contain one apolipoprotein B (ApoB) protein, ApoB concentration may give a better indication of large lipoprotein particle concentration than measurements of cholesterol concentrations alone.
Measurement of lipoprotein subclasses, which include HDL2 and HDL3, intermediate-density lipoprotein (IDL), very-low-density lipoproteins (VLDL1, VLDL2, VLDL3), and lipoprotein(a) [Lp(a)], a particularly dangerous lipoprotein that can lead to heart attacks and strokes.
Levels of LDL, intermediate-density lipoprotein (IDL), and very-low-density lipoprotein (VLDL) must be measured in the fasting state to be accurate, but nonfasting levels of HDL and total cholesterol generally are accurate.
