With as few as seven residues , acyclic α/β‐peptides, which consist of alternating units of ( L )‐alanine and of cis ‐β‐aminocyclopropanecarboxylic acids ( cis ‐β‐ACCs, see structure), form stable 3 13 ‐helix turns in solution. The configuration of the cis ‐β‐ACCs was found to be crucial for the helical structure of this new class of foldamers.
