Nanosolvation-induced stabilization of a protonated peptide dimer isolated in the gas phase.
Résumé
A dash of water: Nanosolvation of a leucine-enkephalin peptide dimer by only three water molecules has a dramatic impact on its stability to VUV photon irradiation. A drastic reduction of the fragmentation abundance of the hydrated protonated peptide dimer precursor, isolated in the gas phase, was observed. Calculations show that hydration in fact stabilizes the dimer structure.
