Water Molecule Adsorption on Short Alanine Peptides:  How Short Is the Shortest Gas-Phase Alanine-Based Helix?

Water adsorption measurements have been performed under equilibrium conditions for unsolvated Ac-A n K+H+ and Ac-KA n +H+ peptides with n = 4−10. Previous work on larger alanine peptides has shown that two dominant conformations (helices and globules) are present for these peptides and that water ad...
