ABSTRACT:
Bioaccumulation of metal ions involves formation of complexes. Solution studies on biomimmetic systems were carried out. Results obtained for nickel(II), L-tyrosine, L-alanine, L-phenylalanine, L-aspartic acid and L-glutamic acid are being presented in this piece of work. All these ligands are physiologically related to each other and are directly or indirectly involved in nerve transduction. These ligands coordinate with metal ions. Equimolar ternary systems involving L-tyrosine were investigated in aqueous medium at different temperatures and ionic strengths in order to find out K, enthalpy, entropy and free energy change of formation of biligand complexes. pH-metric data was subjected to SCOGS Computer program to refine the values as calculated by the method of Martell and Chaberek. Percentage distribution of metal ion over the entire experimental pH range was obtained.
KEYWORDS:
