Figure 7. Calculated diffraction patterns.

(A) A hexagonal packing of the coiled-coils well describes the experimental small angle data in Fig. 5B in non-treated hair. (B) The second peak was found to be increased in intensity after perming, consistent with a structure where some coiled-coils are dissolved into monomers and occupy positions in between the dimer locations. [hkl] indices of the primitive and base centred monoclinic lattices used for the calculation are marked. Cartoons show the arrangements of dimers and monomers within the filaments.
