N-(L-2-Aminobutyryl)-L-alanine and 2-(L-alanylamino)-L-butyric acid 0.33-hydrate

C. H. Görbitz

Abstract: The crystal structure of N-(L-2-aminobutyryl)-L-alanine, C₇H₁₄N₂O₃, is closely related to the structure of L-alanyl-L-alanine, both being tetragonal, while the retro-analogue 2-(L-alanylamino)-L-butyric acid 0.33-hydrate, C₇H₁₄N₂O₃·0.33H₂O, forms a new type of molecular columnar structure with three peptide molecules in the asymmetric unit.

Formula: C₇H₁₄N₂O₃ and C₇H₁₄N₂O₃·0.33H₂O
