摘要
The model tripeptide Boc-beta -Ala(1)-Aib(2)-beta -Ala(3)-OMe 1 [beta -Ala: beta -alanine, Aib: alpha -aminoisobutyric acid] forms an infinite parallel beta -sheet structure through intermolecular interactions in single crystals and from the SEM diagram of this peptide, it is evident that the compound has fibrillar morphology, a characteristic of neurodegenerative disease causing amyloid aggregate.
