L-Asparaginyl-L-valine 1.33-hydrate

The title compound, C₉H₁₇N₃O₄·1.33H₂O, crystallizes with three peptide mol­ecules and four water mol­ecules in the asymmetric unit. Two of the peptide mol­ecules contain an intramolecular hydrogen bond between the N-terminal amino group and the asparagine side chain. Valine side chains aggregate into large hydro­phobic columns.
