Abstract: We present the results of quantum-chemical simulation of two types of molecular complexes of glycine with phosphine oxide H$_{3}$PO, interacting through a proton or a Ca$^{2+}$ cation. The formation of the glycine–Ca$^{2+}$–phosphine oxide complex is energetically more favorable than the formation of a complex with a hydrogen bond. The results present hope that free amino acids can be used to decrease the concentration of calcium cations in regions damaged by calcifications.
Keywords: amino acids, glycine, complexation, calcification, noncovalent interactions, hydrogen bond.
