摘　　要：Metal glycinate chelates are formed by glycine and metal compounds through chemical reactions.Calcium glycinate,magnesium glycinate and zinc glycinate are kinds of new-type and ideal nutrient supplements,which have satisfactory physico-chemical properties and bioactivities.They are important for prophylaxis and treat metal deficiency.The structural characterization shows that the metal ion is bonded to the amino and carboxyl group to form two five-membered rings.This paper mainly studies the structure characterization of the metal chelated glycinates by their solubility,infrared spectrum,thermal analysis,mass spectrometry,polycrystal difrac-tion,the metal contents and glycine contents of calcium glycinate,magnesium glycinate and zinc glycinate.

关 键 词：Calcium glycinate magnesium glycinate zinc glycinate structure charact erization.
