摘要: We report the investigation of collision-induced dissociation (CID) and electron-capture (ECD) product fragmentations supermetallized complexes Substance P several monovalent metals. The supermetallization is phenomenon formation complex ion peptide–metals in gas phase when peptide accepts an unexpectedly large number have obtained investigated with incorporation up to four cesium (Cs), five potassium (K) six silver (Ag) atoms. current research reveals crucial changes behavior cases different It was observed that CID spectra Cs K dominated by peak corresponding loss metal cation while ECD gives a rich fragmentation. In case Ag, Ag+ occurs shows good
