Selenium metabolism and function.
Selenium like many other elements has a bimodal effect. At lower concentrations selenium is an essential trace element necessary for the growth of man and animals. However, at higher concentrations, selenium has toxic properties for man and animals. The biochemistry of selenium as a component of glutathione peroxidase and the analytical properties of selenium are also outlined.
