Study of electrical conductance of Albumine in water and it’s reaction with alkali metal ions
Abstract
Interactions of bovine serum albumin with some alkali earth metal ions Na+, K+, Mg+2,Ca+2,were investigated to give the effect of metal molecular structure on complex formation of metal-protein molecules. To elucidate the interactions, the protein-metal combination in aqueous buffer solution of pH values (4,7and8.2) and at37°Cwere investigated using conductivity, straight lines from the plot of specific conductivity against its concentration were gives at pH 7 which is chosen because it is near the pH of blood serum. Besides, the conductivities of albumin with each of solutions of some alkali earth metal chlorides (NaCl, KCl, MgCl2, CaCl2) at pH7 were measured. The plot of specific conductivity against each mixture solution were discussed.
