Related to lipoprotein lipase: Lipoprotein lipase deficiency

lip·o·pro·tein li·pase

(lip'ō-prō'tēn lī'pās, lī'pō-),
An enzyme that hydrolyzes one fatty acid from a triacylglycerol; its activity is enhanced by heparin and inactivated by heparinase. It is activated by apolipoprotein C-II; a deficiency of lipoprotein lipase is associated with familial hyperlipoproteinemia type I.

lipoprotein lipase

/lipo·pro·tein li·pase/ (li´pās) an enzyme that catalyzes the hydrolytic cleavage of fatty acids from triglycerides (or di- or monoglycerides) in chylomicrons, very-low-density lipoproteins, and low-density lipoproteins.

lipoprotein lipase (LPL)

an enzyme that plays a key role in breaking down triglycerides present in chylomicrons and very low-density lipoprotein particles, releasing their fatty acids for entry into tissue cells.

lip·o·pro·tein li·pase

(lip'ō-prō'tēn lip'ās)
An enzyme that hydrolyzes one fatty acid from a triacylglycerol; its activity is enhanced by heparin and inactivated by heparinase.

lipoprotein

any of the macromolecular complexes that are the form in which lipids are transported in the blood. They consist of a core of hydrophobic lipids covered by a layer of phospholipids and apoproteins, which make the complex water-soluble. There are four main classes of lipoproteins: chylomicrons, in which lipids are transported after a meal from the intestine to tissues, where they are stored or used; very low density lipoproteins (VLDL); low density lipoproteins (LDL); and high density lipoproteins (HDL). VLDL and HDL are produced by both the liver and the intestine; LDL is produced by the metabolism of VLDL.

α-lipoprotein
high density lipoproteins which migrate in the alpha position in paper chromatography. Inherited deficiency of these proteins is described in humans but there is no known animal model of the disease.
lipoprotein factor Xa inhibitor
a blood coagulation inhibitor present in the low density lipoprotein fraction of plasma.
high density lipoprotein (HDL)
a fraction of lipoproteins separable by ultracentrifugation.
intermediate density lipoprotein (IDL)
intermediate in density between LDL and VLDL; migrate in electrophoresis with β-globulins.
lipoprotein lipase
specific lipase hydrolyzing lipoproteins.
