Fig. 5.

Model of Aβ^{20–34, isoAsp23} as the core of an Aβ 1–42 modified polymorph. a Model of Aβ^{1–42, isoAsp23} centered on interface A. b Centered on interface B. Blue residues correspond to the crystal structure core (Aβ^{20–34, isoAsp23}), gray sticks correspond to the modeled extension (1–19 and 35–42)
