Glass transition in aqueous solutions of glucose. Molecular dynamics simulation

We have simulated by molecular dynamics the melting and glass transition of aqueous solution of glucose in a wide concentration range. The simulated glass transition temperature (Tg) are in good agreement with experimental values but the obtained melting temperatures of relatively diluted solutions are below the experimental ones. The ‘glass’ branch of the temperature-concentration state diagram is quite acceptable and opens the possibility of reliable simulation of vitrification processes in carbohydrate solutions.
