Fragmentations of N-benzyloxycarbonyl-protected tri-peptide ethyl esters containing proline at the P2 site were compared with those of the corresponding peptide derivatives containing no proline in field desorption mass spectrometry. The fragment ion [M-107]+ due to a loss of the benzyloxy group from a molecular ion was observed in the field desorption mass spectra for the peptides containing no proline, while it was not found in the peptides containing proline at all. These results suggest that the conformational difference of the peptide derivatives attributable to the existence of proline has an effect upon fragmentations in the field desorption ionizing process.
