Abstract

The classical conformational energy calculations described and applied to various amino acid residues in earlier papers of this series have now been extended to the side chain of arginine residue. The extended Huckel-type calculations were carried out for the model compound, N-methylguanidine, in order to predict the barrier to rotation about the C-N bond of the guanidyl group. The theoretically predicted conformations for the arginine side chain are found to be in excellent agreement with observations.
