Natural phosphatidylcholines, phosphatidylethanolamines and sphingomyelins have been investigated by field desorption and fast atom bombardment mass spectrometry. It is demonstrated that using these soft mass spectrometric ionization techniques, accurate, fast, and sensitive fatty acid profiling of
Chemical ionization and fast atom bombardment mass spectra of a series of phospholipids related to PAF-acether are reported. The usefulness of these methods towards their structural determination is discussed. The mass spectra of sphingomyelin are also examined.
Ammonia desorption chemical ionization mass spectra (NH3-DCIMS) of phosphatidylsulfocholines, a mixture of a homologous series of phosphatidylsulfocholines (PSC) and a mixture of a PSC and a phosphatidylcholine (PC), were measured by a flash heating method involving introduction of 1/xg of the sampl
