The reaction of diazomethane with synthetic phosphatides and with insect lipid extracts
1.
1. The reaction of diazomethane with synthetic phosphatidylethanolamine, N-methylphosphatidylethanolamine, phosphatidylcholine and insect-lipid extracts was studied in order to find out if the reaction was specific to one type of phosphatide.
2.
2. The three synthetic phosphatides reacted in essentially the same manner, although with different rates of reaction, forming dimethyl esters of phosphatidic acids and a nitrogenous compound similar to neurine. The results with insect extracts gave evidence of the reaction of diazomethane with many natural phosphatides.
3.
3. N-methylation of the intact ethanolamine phosphatides occurred to a limited extent and was increased by the presnece of alcohols in the reaction medium.
4.
4. Techniques used included column chromatography on silicic acid, paper chromatography and infrared spectroscopy.
