From: Iodine staining as a useful probe for distinguishing insulin amyloid polymorphs
Schematic illustration for the binding of the polyiodides on the surface of amyloid fibrils. In this figure, I5− and (I3−)2 are shown as tentative examples of polyiodides, and two possible candidates for the binding sites of polyiodides, i.e., the grooves of the pleated cross-β structure (model I) and the edge of β-sheets (model II), are represented.
