Peptide models XXV. Side-chain conformational potential energy surface, E = E(χ1, χ2) of N-formyl-L-aspartic acidamide and its conjugate base N- formyl-L-aspartatamide in their γ(L) backbone conformations

Ab initio molecular computations were carried out on the γ(L) backbone conformation of N-formyl-L-aspartic acidamide and its conjugate base N- formyl-L-aspartatamide at the HF/3-21G level of theory. All side-chain conformations were explored for the parent amino acid diamide and its conjugate base....

Sumario:Ab initio molecular computations were carried out on the γ(L) backbone conformation of N-formyl-L-aspartic acidamide and its conjugate base N- formyl-L-aspartatamide at the HF/3-21G level of theory. All side-chain conformations were explored for the parent amino acid diamide and its conjugate base. Propionate ion, propionic acid, 3,3-difluoropropionate ion and 3,3-difluoropropionic acid were used to model the side-chain in the anionic and neutral compounds.
