In the fibers, they have a clockwise, staggered orientation that leads to an overall right-handed helical structure. These structures, in turn, self-assemble to form coiled-coil aggregates with left-handed helicity.

A maximum in optical activity is observed in the supramolecular aggregates of a 3:1 mixture with a-SQ-1 as the major component. Intriguingly, the highest spin-selective electron transport is observed …
WebHelicity was proved to play a crucial role on peptide specificity and biological activities.
