Conformation self-aggregated -sheets

Self-assembly of chiral molecules may result in organized aggregates displaying a remarkable enhancement of ophcal achvity. The best known examples are amino-acid residues that assume a periodic conformation - an a-helix or a p-sheet chain. In this case, the enhancement of optical activity is due to the onset of a parhcular rigid conformation. [Pg.97]

Self association seems to be related to a degree of conformational freedom. Smaller peptides with well defined architecture, such as oxytocin have not been observed in aggregated form so far. On the other hand many blocked intermediates in peptide synthesis exhibit annoying insolubility in organic solvents because of their tendency for aggregation in the form of jS-sheets. [Pg.44]
