Characterization of Saponifiable Lipids and Characterization & Isolation of Complex Lipids Jan Kevin Roxas‚ Nashiba Samad‚ Erickson Santos Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Lipids building blocks of different organic material that are water insoluble. This can be divided into simple and complex lipids that have several forms like waxes‚ triacylglycerols‚ phosphoacylgylcerols‚ sphingolipids‚ eicosanoids‚ isoprenoids and many other. To identify‚

Isolation and Characterization of Complex Lipids Shea Kathleen Guinto‚ Peter Julius Dale Inocando*‚ SooHyun Jung‚ Jurilla Camille Louise Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract In this experiment an egg yolk will serve as the sample to isolate lipids and separate them into two classes which is the phosphorylated lipid and the non-phosphorylated lipid. The isolated lipids are then characterized through a series of color chemical tests along with the given

conducted in order to know how green tea reduce the risks of cardiovascular diseases. However‚ the results are inconsistent and the mechanisms remain unclear. In this review article‚ the potential mechanisms will be showed from five aspects: lowering cholesterol level‚ inhibiting oxidation of LDL‚ improving vascular endothelial function‚ decreasing blood pressure and having anti-atherosclerotic effect. In the discussion part‚ the adverse effects of high consumption of green tea will be showed. To sum up
