Реферат:	eng: Solid mixtures of ice with three glycine polymorphs were heated up to the eutectic melting and the DSC has detected the eutectic temperatures of -2.8 C for α-, -3.6 C for β-, and -2.8 C for γ-glycine. DSC peaks of the eutectic melting are rather strange in shape, indicating unclear processes in the solutions. Accurate DSC measurements of extremely small samples can probably provide us with the physicochemical tool for the investigation of polymorphic differences among different solutions. This may be important in relation to different bioavailability of solutions prepared from different polymorphs. Eutectic temperature of -4.7 C in water-glycine system allows us to suggest that the unknown polymorph of glycine exists. © 2012 Akadémiai Kiadó, Budapest, Hungary.
