Both the and DtV$ for the glycyl dipeptides increase with increasing molality of sodium acetate. The interactions between charged center or glycyl units of the peptide and ions dominate those between alkyl groups of the peptide and the ions. The interaction between the peptides and sodium acetate is mainly pairwise. The results were interpreted successfully by the cosphere overlap model.
