A single crystal X-ray diffraction study of the tetrapeptide Boc-Ala 1 -Aib 2 -Leu 3 -Aib 4 -OMe 1 (Aib: a-aminoisobutyric acid) reveals that it forms a supramolecular helix through continuous intermolecular hydrogen bonds. Scanning electron microscopic studies show that this peptide exhibits amyloi
