Potential energy surfaces for the gas-phase interaction between alpha-alanine and alkali metal ions (Li (super)+, Na (super)+, K (super)+). A density functional study

Research has been conducted on the alpha-alanine and the stable adducts if forms with lithium, sodium and potassium cations. The study of the conformations of these alanine and adducts has been performed via the density functional theory and the results are discussed.
