Protonated dipeptide losses from b 5 and b 4 ions of side chain hydroxyl group containing pentapeptides
In this study, C-terminal protonated dipeptide eliminations were reported for both b 5 and b 4 ions of side chain hydroxyl group (-OH) containing pentapeptides. The study utilized the model C-terminal amidated pentapeptides ...
Non-direct sequence ions in the tandem mass spectrometry of protonated peptide amides - An energy-resolved study
The fragmentation reactions of the MH+ ions of Leu-enkephalin amide and a variety of heptapeptide amides have been studied in detail as a function of collision energy using a QqToF beam type mass spectrometer. The initial ...
