Figure 2From: Amyloid β-protein oligomers and Alzheimer’s diseaseSimulation of amyloid β-protein hexamer formation. Formation of an amyloid β-protein (Aβ)40 hexamer from a tetramer (lower left) and a dimer (upper right). β-strands are depicted as yellow ribbons, turns as light blue ribbons and random coils as white ribbons. The N-termini are represented by red spheres. The C-terminal V39 and V40 are represented by orange spheres.
