• atoms
  • Macrocyclic stereocontrol refers to the directed outcome of a given intermolecular or intramolecular chemical reaction, generally an organic reaction, that is governed by the conformational or geometrical preference of a carbocyclic or heterocyclic ring, where the ring containing 8 or more atoms.

  • structure
  • The distinctive cyclic structure of proline's side chain gives proline an exceptional conformational rigidity compared to other amino acids. (wikipedia.org)
  • The exceptional conformational rigidity of proline affects the secondary structure of proteins near a proline residue and may account for proline's higher prevalence in the proteins of thermophilic organisms. (wikipedia.org)
