Abstract:However, by carefully accounting for differences between gas-phase and solution-phase systems, a better understanding of how competitive noncovalent interactions affect the hydration and structure of flexible biomolecules can be gleaned. By systematically probing inherent gas-phase properties, such as, solvation shell size and occupancy (using K(DFB)m(H2O) n clusters to mimic the weaker ion-molecule interactions present in solution) and cluster temperature (varying the evaporative ligand to obtain clusters in the 250-350 K or 50-150K temperature ranges). These lessons are then applied to understanding the impact of a charged species on the hydrogen-bonded topology and conformational flexibility of small biomolecules: M+(n-methylacetamide)(H 2O)n, M+(indole)m(H2O) n, and M+ (tryptamine)(H2O)n.
