Table 2.
The elastic moduli in GPa for the Aβ40, Aβ42 and α-syn from experiment and our CG model. The structural symmetry of β-amyloid (if specified in the literature) is given next to the PDB entries. The experimental results regarding indentation for Aβ42 and α-syn have been taken from [30]. The experimental values for the shear modulus (S) for β-amyloids have been taken from [62], while the experimental values of S and YL for α-syn are currently unknown.
