Synthetic Route of 555-43-1, A common heterocyclic compound, 555-43-1, name is Propane-1,2,3-triyl tristearate, molecular formula is C57H110O6, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: An assay mixture consisting of 1 ml of liquid ester or 1 g of solid ester, 3 ml of isopropanol, 5 ml of phosphate buffer (pH=8.0), and 1 ml of the lipase solution was incubated for 15 min at 30C with stirring at 180 rpm. The reaction was terminated by the addition of 95% ethanol, and the amount of liberated fatty acids after incubation was determined by titrating with 50 mM NaOH in the presence of two drops of phenolphthalein solution as the indicator. The control experiment was performed under the same conditions with the addition of 95% ethanol prior to the reaction. One unit of lipase activity was defined as the amount of enzyme required to liberate 1 mumol of free fatty acid per minute under the experimental conditions.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
