Abstract
The hydration number of the glycine amino acid in aqueous sodium chloride solution is less than in aqueous urea solution; the difference increases significantly with increasing concentration of the nonaqueous component. Given the same partial volume of water, the hydration numbers of glycine in the two systems are close together (δ ≈ 5%).
