Interaction of the racemic helical homo-octapeptide made by the achiral C(α)-methyl alanine (Aib) amino acid with a chiral enantiopure micellar aggregate made 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.
由非手性 C(α)-甲基丙氨酸(Aib)氨基酸组成的外消旋螺旋同八肽与手性对映纯胶束聚集体相互作用,导致螺旋 Aib 序列的外消旋化,从而使我们首次在水中获得了无任何手性氨基酸贡献的 310 螺旋的 CD 特征。
