Densities of glycine in various aqueous urea,monomethylurea(MMU),dimethylurea (DMU) solutions have been measured at 298.15 K with an Anton Paar Model 55 densimeter.From these densities,apparent molar volumes and limited partial molar volumes have been calculated; transfer volumes from water to aqueous urea,MMU,DMU solutions have also been obtained.Furthermore,the hydration numbers and volumetric interaction coefficients for glycine were evaluated.Solvent effect was discussed in detail.The results show that all of the transfer volumes in different solutions are positive,and increase with increasing the co-solutes (urea,MMU,DMU) concentration; the hydration numbers for glycine in three solutions all decrease with increasing the co-solutes concentration.It was concluded that interaction between amino acids and urea,MMU,DMU molecule is dominated by 1:1 form from the results of the volumetric interaction coefficients.
