A GC-EIMS method to determine the structure of the fatty acid chains in cyclic lipopeptides is described. The structure of the fatty acid chains can be determined by the characteristic peaks of the MS spectrogram according to the fact that the alpha cleavage predominates the MS of a fatty acid with amino and hydroxy groups, while the McLafferty rearrangement predominates the MS of one without amino or hydroxy group. The characteristics of the strongest peaks of 103 and 102 in MS spectrograms… CONTINUE READING
