  • 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)
