摘要：

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 (T-g) 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.
