Abstract

original image

Bleib positiv! Die Dissoziation eines Lanthankomplexes von Triglycin erzeugt ein neuartiges diprotoniertes Iminiumion (siehe Bild; grau C, weiß H, hellblau La, dunkelblau N, rot O), das vielfältige Fragmentierungen eingeht. Diese Klasse von Peptidfragmentionen bietet sich an, um die Auswirkungen von Mehrfachladungen zu modellieren, und könnte sich für die Peptidsequenzierung eignen.
