| Abstract: | The hydration numbers are investigated of the glycine amino acid in solutions of substances with different effects on the structure of water: urea, monomethylurea, and 1,3-dimethylurea. Glycine loses a half of its hydration water in a 20m urea solution and only a quarter of it in a 20m dimethylurea solution. The constancy of the hydration number of glycine in concentrated dimethylurea solutions is due to the compensatory effect of the interactions in the ternary and binary systems. |
