Metal Ions and Enzymes
Metal Ions and Enzymes by Wenshe Liu A wide variety of metal ions are found in the environment and in the body. They serve many functions in proteins, the most important of which is the modification of protein structures, enhancement of the structural …
AN INTRODUCTION TO COMPLEX METAL IONS
Complex metal ions containing more complicated ligands In the examples we’ve already looked at, each ligand only forms one bond with the central metal ion to give the complex ion. Such a ligand is said to be unidentate. That means literally that it only has

Solution for Metal ions are named by naming the element and adding the word ion. Metal ions that have variable charge need roman numerals to indicate their… Social Science
A coordination complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.   Many metal-containing compounds, especially those of transition metals (d block elements), are coordination complexes.

Oxidation-reduction reactions of metal ions.
Several metal or metalloid ions exist in multiple oxidation states and can undergo electron transfer reactions that are important in biological and environmental systems. There are endogenous metal ions such as iron, copper, and cobalt that participate in oxidation-reduction reactions with species of oxygen like molecular dioxygen, superoxide, and hydrogen peroxide. These reactions may be
Measuring Metal Ions
From mining to electroplating, a wide range of processes require online monitoring of metal ions in solution. A major application is analysis of metal ion concentrations in wastewater for environmental reasons and for regulation of water treatment processing.
Hydrated metal ions in aqueous solution: How regular are their …
· PDF 檔案Metal ions with d10s2 valence shell electron configuration may have a stereochemically active lone electron pair (hemi-directed complexes) or an inactive one (holo-directed). The hydrated tin(II), lead(II), and thallium(I) ions are hemi-directed in aqueous solution
Metal ions and RNA folding: a highly charged topic with …
How different metal ions enable RNAs to fold depends on the electrostatic potential of the RNA and correlated fluctuations in the positions of the ions themselves. Theoretical models, fluorescence spectroscopy, small angle scattering and structural biology reveal that metal ions alter the RNA dynamics and folding transition states.
