N1 - Focus: Peptide Fragmentation Extensive 15N labeling and multiple-stage tandem mass spectrometry were used to investigate the fragmentation pathways of the model peptide FGGFL during low-energy collision-induced-dissociation (CID) in an ion-trap mass spectrometer. Of particular interest was formation of a 4 from b 4 and a* 4 ( a 4-NH 3) from a 4 ions correspondingly, and apparent rearrangement and scrambling of peptide sequence during CID.
