High resolution structural characterization of Aβ42 amyloid fibrils by magic angle spinning NMR.

This suggests that there may be significant structural differences between Aβ M01–42 fibrils and Aβ M01–40 fibrils, which may be a result of their different hydrophobicities and steric constraints related to accommodating two extra residues within the fibril. 71 Furthermore, we note that the location of the β-strands in this work are in slightly different locations compared to many of those reported for Aβ 1–40 fibrils.
