zincdependent regulation of zinc import and export genesjun 09, · considering the amount of zinc in the medium (1.33 μm), this reveals more than 1,f zinc concentration in the cell. this level is higher than the zinc quota of e. coli,zinc in drinkingwater whoin tapwater, the zinc concentration can be much higher as a result of the leaching of zinc from piping and fittings (2). the most corrosive waters are those of low ph, high carbon dioxide content, and low mineral salts content. in a finnish survey of 67% of public water supplies, the median zincanalyzing free zinc(ii) ion concentrations in cell biologymeasurement of total zinc is relatively straightforward with analytical techniques such as atomic absorption/emission spectroscopy or inductively coupled plasma mass spectrometry. total zinc concentrations of human cells are 0300 μm. in contrast, the pool of nonprotein bound zinc is mostly examined with fluorescence microscopy/spectroscopy.cited by 2zinc overviewbiological rolecharacteristicscompounds and chemistryhistoryproductionapplicationsprecautions
zinc is an essential trace element for humans and other animals, for plants and for microorganisms. zinc is required for the function of over 300 enzymes and 1 transcription factors, and is stored and transferred in metallothioneins. it is the second most abundant trace metal in humans after iron and it is the only metal which appears in all enzyme classes.
