Kinetics and mechanism of complexation of Ni(II) and Co(II) with L-2-Amino 3-mercapto propionic acid
Author(s): Haritma Chopra, Malhotra HC
Abstract: L -2- Amino 3-mercapto propionic acid (Cysteine) is an amino acid with immense biological significance. The kinetic study involving interaction of Ni (II) and Co (II) with L-Cysteine was carried out under first order condition. The concentration values were chosen to be such the only mono-complex formation was possible. The investigations were carried out at 20, 25, 30 and 35 (±0.05) oC. A scheme consistent with the fact that (-S) atom acts as the bridging ligand even though the deprotonated from of the ligand predominates at pH 7.7 only. The overall rate constant has been resolved into stepwise rate constant.
