Crystallographic Study

β-Alanine is an amino acid which is important in the design of diverse peptides. Crystallographic study shows that the N-acyl adduct of β-Alanine, an ω-amino acid important in peptide design for the production of structural and functional diversities, and N,N′-dicyclohexyl urea(DCU) forms a turn like structure without any intra-molecular hydrogen bonding.
