Two-dimensional 13C/13C exchange solid-state NMR spectrum of fibrillized
Alzheimer's �-amyloid peptide fragments (16-22 residue: KLVFFAE)
uniformly 13C- and 15N-labeled from L17 though A21. Assignments of the
signals are given in the figure. Analysis of spectral line widths and
chemical shifts demonstrates well ordered structures and �-sheet
formation all through the molecule.http://chem.uic.edu/chemistry/people/faculty/yoshitaka-ishii
