Modulation of intra- and inter-sheet interactions in short peptide self-assembly by acetonitrile in aqueous solution |
RDFs between different groups of solvent and peptide monomer. (a) RDFs between water and peptide molecules in pure water. (b) RDFs between water and peptide molecules in the ACN/water mixture. (c) RDFs between ACN and peptide molecules in pure ACN. (d) RDFs between ACN and peptide molecules in the ACN/water mixture. OW represents the oxygen atom of water, CT the methyl carbon of ACN, NZ the nitrogen of ACN, CG2 the side chain carbon of isoleucine, N the backbone nitrogen of isoleucine, and O the backbone oxygen of isoleucine. All of these atoms have been labeled in Fig. |
