Triacylglycerol lipase activities of homogenates and subcellular fractions of rat liver were measured under optimal conditions at pH 7.5 using emulsified tri[1-14C]oleoylglycerol as substrate. Twenty-four hr after administration of streptozotocin, hepatic alkaline lipase activity was 39% of normal, and this lower level of activity was observed at 72 hr and 7 days, after streptozotocin injection...

The tremendous mounting interest in lipase production is pertinent to the biotechnological applications that these enzymes offer. Lipase, belonging to the hydrolyze enzymes, is involved in copious biological functions including: hydrolysis insoluble triacylglycerol to mono and diacylglycerols and glycerol. Submerge fermentation technique was applied for the efficient production of this. Briefly...

To improve the reusability and organic solvent tolerance of microbial lipase and expand the application of lipase (hydrolysis, esterification, and transesterification), we immobilized marine microbial lipase using different methods and determined the properties of immobilized lipases. Considering the activity and cost of immobilized lipase, the concentration of lipase was fixed at 2 mg/mL. The ...

The ontogenesis and specific activities of pancreatic (trypsin, chymotrypsin, amylase and lipase) and intestinal enzymes (alkaline phosphatase, aminopeptidase N) were investigated in Kutum (Rutilus frisii Kutum) from the onset of exogenous feeding (3 day after hatching, DAH) to the juvenile stage at 50 DAH. Trypsin- and chymotrypsin-specific activity showed similar patterns and increased with l...

Dietary triglycerides are hydrolyzed in the small intestine principally by pancreatic lipase. Following uptake by enterocytes and secretion as chylomicrons, dietary lipids are cleared from the bloodstream via lipoprotein lipase. Whereas lipoprotein lipase is inhibited by several proteins including Angiopoietin-like 4 (Angptl4), no endogenous regulator of pancreatic lipase has yet been identifie...

Lipoprotein lipase (LP lipase, triacylglycero-protein acylhydrolase EC 3.1.1.34) activity was found in four dissimilar brain regions (hypothalamus, cortex, cerebellum, and midbrain) of adult male rats. Progressive accumulation of LP lipase activity in cultured fetal rat hypothalamic cells was also observed, indicating de novo synthesis of the lipase. The brain LP lipase activity was serum-depen...

Treatment of 3T3-Ll adipocytes with either an oleanolic acid gtycoside or a 2orS>-protopanaxatriol g]ycoside increased the secretion of lipoprotein lipase activity into the medium dose-dependently. At a concentration of 100pg/ml, ginsenosides Ro, Re, Rgi, and Rhi increased the secretion of lipase activity into the medium by 119, 107, 56, and 32%, respectiyely. The ratio of lipase actiyity in th...

in this study, the effects of dietary egg lecithin on digestive enzymes and body biochemical composition of juveniles mesopotamichthys sharpeyi was evaluated. four experimental diets including control diet (with 0% egg lecithin) and three diets containing 2%, 4% and 6% egg lecithin were used. at the end of the experiment, digestive enzymes activity (lipase, amylase and alkaline phosphatase) and...
