Gas-liquid chromatography-mass spectrometry of synthetic ceramides containing phytosphingosine
Journal of Lipid Research, 1970 Ceramides containing phytosphingosine as base and one of the fatty acids 16:0, 18:0, 20:0, 22:0, 23:0, and 24:0, were prepared by direct coupling in the presence of a mixed carbodiimide. The ceramides were analyzed as the 1,3,4-tri-O-trimethylsilyl ether
