Özet

The adsorption dynamism of certain amino acids [alanine (Ala), serine (Ser), lysine (Lys), proline (Pro), and aspartic acid (Asp)] on crosslinked diethylaminoethyl (DEAE) dextran microbeads was investigated with electronic spectroscopy in aqueous solutions. Among the selected amino acids, Ala-Pro and Ser-Lys showed similar adsorption dynamism, but Asp showed the strongest tendency for adsorption. The interaction dynamism of Asp with crosslinked DEAE dextran microbeads was studied to determine the mechanism of this adsorption. (c) 2005 Wiley Periodicals, Inc.
