Deracemization and the first CD spectrum of a 310-helical peptide made of achiral a-amino-isobutyric acid residues in a chiral membrane mimetic environment+?

Interaction of the racemic helical homo-octapeptide made by the achiral Ca-methyl alanine (Aib) amino acid with a chiral enantiopure micellar aggregatemade of N-dodecylproline led to the deracemization of the helical Aib sequence thus allowing us to obtain for the first time the CD signature in water of a 310 helix devoid of the contribution of any chiral amino acid.
