Abstract

The sequences of polypeptide chains which are built up with alternating hydrophilic-hydrophobic residues concentrate them-selves in the β-pleated sheet conformation when dissolved in salted water. The sheets are more stable than the α-helix and are shown to constitute a pathway to the enrichment in one enantiomer. They are considered as a single system with potential template activity.
