Descrição

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 sol ubility in aqueous electrolyte solutions can therefore be useful for the design of separation processes and, also, be related to protein chemistry, providing an important insight into the interactions present in those complex solutions. Previous studies we re focused on the effect of salts in the solubility of glycine, DL - alanine, L - isoleucine, L - threonine and L - serine [ 1 - 3 ] . This work extends that analysis to four additional AA, containing two carboxylic groups or the aromat ic ring.
