Abstract
Obesity has existed for a very long time. Obesity leads to improper physiological metabolism, which in turn produces a host of physiological and social issues in addition to aesthetic concerns. Individuals are working to discover anti-obesity medications and other safe and efficient treatment options. Because pancreatic lipase (PL) is essential to human fat metabolism, PL inhibitors are now used to treat obesity in clinical settings. This research involved partially purifying lipase from the ovine pancreas. One lipase isoenzyme was identified using the CM-Cellulose ion exchange chromatography technology. It had a specific activity of 2.467 U/mg protein and a recovery of 272 in comparison to the crude extract. The molecular weight was determined to be 33.8 kilodaltons, and the electrophoresis method produced only one band. Using p-nitrophenyl acetate as a substrate, the capacity of willow bark extracts to inhibit partly purified pancreatic lipase activity was investigated.
The inhibitory percentages via treating the enzyme with EthOH 70% and H2O were found to be 27.14 and 61.43 respectively. Furthermore, the Lineweaver-Burk plots revealed the inhibition modes noncompetitive with both extracts.
