Metal-Ion-Coordinating Properties of Various Amino Acids, Investigation of the Essential Function in Biological Systems regarding to their Nano-Structure
(Islamic Azad University - Varamin Branch, 2012-04-01)The acidity constants of some amino acids (Am) were determined by potentiometric pH titration. The stability constants of the 1:1 complexes formed between M2+: Ca2+, Mg2+, Mn2+, Co2+, Ni2+, Cu2+ or Zn2+ and Am2-, were ...
