Mass spectrometry of triglycerides: II. Specifically deuterated triglycerides and elucidation of fragmentation mechanisms

Deuterium labeled monoacid triglycerides were synthesized and their mass spectra were measured. The spectra provided further support for proposed (1) structures of principal ions, knowledge about the formation of [M-18]+, the interexchange of hydrogen atoms between 2 and the 5,6 or 7 positions and the explusion of part of the alkyl chain.
