title: The smallest alpha,gamma-peptide nanotubulet segments: cyclic alpha,gamma-tetrapeptide dimers.
abstract: [structure: see text] Cyclic tetrapeptides in which alpha-amino acids alternate with cis-3-aminocycloalkanecarboxylic acids dimerize by forming hydrogen bonds between their alpha-faces but not between their gamma-faces, establishing the minimal structural requirements for the novel alpha,gamma-peptide hybrids SPN.
