Structure of the Species in the Copper (II)–L-Histidine System

摘要: The presence of simultaneously existing multiple species were taken into account in interpreting the structures complex Cu(II)–L-histidine system. A refined proton displacement technique was utilized for structure elucidation solution. absorbance and molar extinction individual computed from total distribution over pH range studied. i.r. spectra L-histidine D2O obtained as a function pD. They interpreted view detected given range. results pH, displacement, visible species, infrared data, all combined to make structural interpretations. following modes metal coordination proposed major system: MHA, O(carboxyl) N(imidazole); MH2A2, N(amino) both L-histidines; MA, O(carbo...
