Noncovalent interactions are ubiquitous in molecular interaction and supramolecular self-assembly. As a model system, host–guest complexes between β-cyclodextrin (β-CD) and small molecules have been extensively studied and widely used in a variety of application fields including drug transportation and fluorescence enhancement. However, details on how guest molecules interact with the β-CD hosts to...
In this study, we systematically investigated gas-phase fragmentation behavior of [M + nH + OH]n•+ ions formed from peptides containing intra-molecular disulfide bond. Backbone fragmentation and radical initiated neutral losses were observed as the two competing processes upon low energy collision-induced dissociation (CID). Their relative contribution was found to be affected by the charge state...
