Effect of KCl and (NH4)2SO4 on the solubility of four amino acids in water at 298.15 K

Amino acids (AA)are very important biomolecules, not only for their intrinsic pharmaceutical value, but also, as the building blocks of proteins. The study of their solubility in aqueous electrolyte solutions can therefore be useful for the design of the separation processees and, be related to protein chemistry, providing an important insight into the interactions present in those complex solutions
