Stability constants, log K1 and log K2, of complexes of D-glucosaminic acid with Cu2+, Ni2+, Pb2+, Zn2+, Co2+, Cd2+, and Mn2+were determined by pH titration method. Copper complexes were found to be the most stable and the contribution of OH groups of glucosaminic acid to the complex formation was observed.
