Resumen:
A conformational and electronic study on N-acetyl-L-glutamate-N-methylamide was carried out. Theoretical computational analysis revealed 21 di erent conformations at the RB3LYP/6-31G(d) level of theory. Ab initio calculations at two levels of theory (RHF/3-21G and RHF/6-31G(d)) were also performed. All side-chain conformations were explored for this compound. N-acetyl-L-glutamate-N-methylamide displayed a di erent conformational behaviour in comparison with other amino acids possessing shorter sidechains. These results can be attributed, at least in part, to the side-chain-backbone interactions, which are stabilizing the low-energy conformations in this molecule.
