Resumen:
Ab initio molecular computations were carried out on the gl 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. q2000 Elsevier Science B.V.
