  • The stationary points characterizing the potential energy profiles of the complexation process of the proline unusual α-amino acid with the alkali metal ions M+ (Li+, Na+ and K+) were investigated by density functional theory using the B3LYP hybrid potential and the 6-311++G** basis set. Different types of M+ coordinations on several proline conformers were considered. Results show that Li+, Na+, and K+ cations bind very similarly to the proline. In the M+-proline lowest-energy conformer, the… CONTINUE READING
