Self-assembly intermediates in heterochiral peptides. (a) Chemical structures of the amphiphilic peptides T-W6, T-(wW)3, and T-W(wW)2. (b) Time evolution of CD spectra for T-(wW)3. (c) AFM images of solutions of the two enantiomeric peptides T-W6 and T-w6. (d) AFM images showing the time evolution of the heterochiral (racemic) peptide T-(wW)3, with the proposed structure of the chiral aggregates. (e) Energy landscape of self-assembly pathways for homochiral and heterochiral peptides. Adapted with permission from ref (23c). Copyright 2020 American Chemical Society.
