What's the attraction? The structures of three dipeptides in aqueous solutions were investigated by using a combination of neutron diffraction and computer simulation. In each solution, peptide association was dominated by charge–charge rather than hydrophobic interactions (see the representative snapshot of the peptide/water box for glycyl-L-alanine; the water molecules are depicted by red crosses.)
