Lipids have many important functions. We attach importance to their functions. Aladdin has developed thousands of ester reagent products for scientific researchers.?It contains various fatty acids, glycolipids, terpenoids and steroids, glycosphingolipids and phospholipids, as well as related products involved in enzymatic hydrolysis, lipase, phospholipase and cholesterol esterase.?There are also products related to lipid testing, including total cholesterol (Chol), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C). These products participate in the following important physiological functions.Energy storageThe skeleton of biofilm, such as phospholipid diester layer, cholesterol, protein, glycolipid, glycerol phospholipid and sphingomyelin.Electrical and thermal insulatorAnimal adipose tissue has the functions of heat preservation and protection against mechanical pressure. Plant wax can prevent the evaporation of water.?Electrical insulation: sheath cells of nerve cells, foreskin of wires, nerve short circuit.?Thermal insulation: keep warm in winter, penguins, polar bears, etc.Signaling: steroids.Activator of enzyme: lecithin activation?β-?Hydroxybutyrate dehydrogenase.Glycosyl carrier: in the synthesis of glycoprotein, phosphate polyterpene alcohol is used as the carrier of carbonyl.Precursors of hormones, vitamins and pigments (terpenoids, sterols).Growth factors and antioxidants.Involved in signal recognition and immunity (glycolipids).
