ABSTRACT

The interaction of dimers of glucosamine and acetylglucosamine molecules with sodium ion has been studied using the DFT/B3LYP approach. The optimization of geometrical parameters and vibrational spectra calculations were done under 6-31G(d) basis set, and energies of the reactions were obtained using 6-311 G(d, p) basis set. The enthalpies of the association reactions of the dimers of glucosamine and acetylglucosamine with Na have been determined. The internal hydrogen bonds OH…O and NH…O have been shown to play an important role in conformational behavior of a particular molecule.
