Peptoids, or poly-N-substituted glycines, are a class of peptidomimetics whose side chains are appended to the nitrogen atom of the peptide backbone, rather than to the α-carbons (as they are in amino acids). ==Chemical structure and synthesis== In peptoids the side chain is connected to the nitrogen of the peptide backbone, instead of the α-car...
