Sensitive non-radioisotopic method for measuring lipoprotein lipase and hepatic triglyceride lipase in post-heparin plasma. 1984

S Nozaki, and M Kubo, and Y Matsuzawa, and S Tarui

In this method for measuring lipoprotein lipase (LPL) and hepatic triglyceride lipase (H-TGL) in post-heparin plasma, we determine the released free fatty acids enzymically. After release, they are extracted by Dole 's method (J. Biol. Chem. 235: 2595-2599, 1960), solubilized with Triton X-100, then measured with an enzymic kit (NEFA Kit-K; Nippon Shoji Kaisha Ltd.) after residual turbidity is removed by centrifugation with chloroform. A 5-microL sample of post-heparin plasma suffices to measure the activity of LPL and H-TGL; thus the method is as sensitive as the radioisotopic method. Selective assay of LPL and H-TGL, by adding sodium dodecyl sulfate to inactivate H-TGL or NaCl to inactivate LPL, is also feasible. The mean activities +/- SD of LPL and H-TGL in plasma of normal healthy men were respectively 9.4 +/- 2.3 mumol/h per milliliter (157 +/- 38 U/L) and 20.1 +/- 10.4 (335 +/- 173 U) mumol/h per milliliter (U/L).

UI	MeSH Term	Description	Entries
D008049	Lipase	An enzyme of the hydrolase class that catalyzes the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. It is produced by glands on the tongue and by the pancreas and initiates the digestion of dietary fats. (From Dorland, 27th ed) EC 3.1.1.3.

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.

D008072	Hyperlipoproteinemia Type I	An inherited condition due to a deficiency of either LIPOPROTEIN LIPASE or APOLIPOPROTEIN C-II (a lipase-activating protein). The lack of lipase activities results in inability to remove CHYLOMICRONS and TRIGLYCERIDES from the blood which has a creamy top layer after standing.
