[Mass spectrometric structure analysis of fatty acid mixtures from biological material after gas capillary chromatographical separation].
The identification of mixtures of fatty acids from biological materials is possible by electron impact ionization mass spectra of methyl esters after their capillary gas chromatographic separation. Mass spectra of pyrrolidine derivatives are used for the determination of double bond positions in unsaturated fatty acids. 97 different fatty acids (saturated, unsaturated, branched, cyclic, hydroxy, oxo, epoxy and methoxy) and other compounds (alkanes, halogens, phthalates, ketones, aldehydes) were identified in yeast and bacterial biomasses, lipid-containing animal tissues and human sera as well as fish and plant oils (77 preparations).
