Peptide-based short single β-strand mimics without hydrogen bonding or aggregation.

Generation of short peptides with a single β-strand structure in solution is difficult. Herein, we design a new class of single β-strand peptidic mimics that are stable without self-aggregation in protic and non-protic solvents. Introduction of one present β-strand mimic can induce and propagate the β-strand structure for at least a penta-peptide sequence.
