A novel method for measuring human lipoprotein lipase and hepatic lipase activities in postheparin plasma.
The objective of this study was to establish a new lipoprotein lipase (LPL) and hepatic lipase (HL) activity assay method. Seventy normal volunteers were recruited. Lipase activities were assayed by measuring the increase in absorbance at 546 nm due to the quinoneine dye. Reaction mixture-1 (R-1) contained dioleoylglycerol solubilized with lauryldimethylaminobetaine, monoacylglycerol-specific l...
متن کاملChimeras of Hepatic Lipase and Lipoprotein Lipase
Chimeric molecules between human lipoprotein lipase (LPL) and rat hepatic lipase (HL) were used to identify structural elements responsible for functional differences. Based on the close sequence homology with pancreatic lipase, both LPL and HL are believed to have a two-domain structure composed of an aminoterminal (NHz-terminal) domain containing the catalytic Ser-His-Asp triad and a smaller ...
متن کاملRelationship between plasma high-density lipoprotein concentrations and lipoprotein lipase and hepatic lipase activities in children with hyperlipidaemia.
1. Significant positive correlations were found between the lipoprotein lipase and hepatic lipase activities of post-heparin plasma samples and plasma high-density-lipoprotein (HDL) cholesterol concentrations in 21 children with hyperlipidaemia and six normal adult males. 2. A significant positive correlation was also observed between the two lipase activities and the ratio of HDL cholesterol t...
متن کاملLipoprotein lipase and hepatic triacylglycerol lipase activities in peripheral and skeletal muscle lymph.
We studied the interstitial fluid concentration of two lipid-metabolizing enzymes (lipoprotein lipase and hepatic triacylglycerol lipase) to determine their importance in interstitial modification of filtered lipoproteins. Despite the use of a very sensitive lipase assay (1 nmol of fatty acid release/ml/hr), lipase activities in plasma and in peripheral and skeletal muscle lymph from control do...
متن کاملLipoprotein lipase, hepatic lipase, and carnitine in premature infants.
Twenty six preterm infants were studied at the age of 2, 7, and 26 days. The activities of lipoprotein and hepatic lipase in plasma taken 15 minutes after a heparin bolus of 100 IU/kg had been given and the concentrations of carnitine in serum and urine were measured. The mean gestational age was 31 weeks (range 26-35 weeks) and birth weight 1580 g (range 840-2280 g). Thirteen infants weighed u...
