· Journal of the American Chemical Society (U.S.)
The formation constants of Cu/sup 2+/ Ni/sup 2+/ and uranyl complexes of glycylglycine, glycine amide, histidine, and histidine ester have been measured and compared. The predominant coordination sites of histidine toward Cu/sup 2+/, Ni/sup 2+/, and uranyl ions are probably the "pyridine" nitrogen of the imidazole group and the amino group. The rates of alkaline hydrolysis of histidine methyl ester have been determined in the presence and absence of metal ions and it was found that an increase in the stability of metal-ester complex is accompanied by an increase in the bimolecular rate constant.
