Study of Interactions between Cysteine and Cadmium(II) Ions using Automatic Pipetting System off-line Coupled with Electrochemical Analyser Dedicated United Nation Environment Program: Lead and Cadmium Initiatives

Popis výsledku v původním jazyce

The sulfhydryl group of low molecular thiols including cysteine is reactive and is often found conjugated to other molecules such as nitric oxide and/or metal ions via its sulfhydryl moiety. Therefore, it is not surprising that thiols play key role in many protective mechanisms against adverse effects of metal ions. On the other, good affinity of their -SH moiety can be used as a base for heavy metal ion sensor in environmental analysis. Electrochemical measurements were performed Trace Analyzer and autosampler, using a standard cell with three electrodes and cooled sample holder (4 degrees C). For automated samples handling prior to their electrochemical and photometrical analysis, an automated pipetting station with computer controlling was used. Ellman reaction for -SH group detection was measured using Chemical Analyser. In this study, we primarily aimed our attention on studying of basic electrochemical behaviour of cadmium(II) ions and low molecular mass thiol cysteine.
