Average number of polar and nonpolar contacts between Aβ and Dec-DETA or Pep1b for each peptide-conformation class^a.

aThe mean values (± standard deviations) were calculated for the three peptide-conformation classes ((1) RMSD<2.0 Å, (2) 2.0 Å≤RMSD<4.0 Å, and (3) RMSD≥4.0 Å) using all ten trajectories of each system. bAveraged over periods with at least one HB between Aβ and Dec-DETA or Pep1b. cAveraged over periods with at least one C-C or C-N contact between the Aβ middle nonpolar part and the nonpolar part of Dec-DETA or Pep1b.
