Synthesis of Calcium-Glycine (Ca-Gly) complex by using Chicken Egg Shell

Abstract

The complex Ca(Gly)2 was synthesized and the chemical composition and structure were studied. We successfully extracted calcium infrom of calcium carbonate from egg shell and synthesis it with glycine. The colorless, crystalline hydrates Ca(gly)2.H2O has been isolated. The compound is readily soluble in water. Structural diversity is also observed with the binding modes of the two aminocarboxylate ligands and the one calcium environment. The Ca(Gly)2.H2O structure is proposed by 3D structure, 1H NMR and 13C NMR by using Chemdraw 12.0 software as per data available in literature.
