title: [Biochemical role of selenium].
abstract: The molecular mechanisms of selenium regulation of biochemical functions in animal and human tissues are presented in review. It is shown, that in spite of high toxicity selenium is an essential nutrient for people and animals. Taking into account deficit of this microelement in fodder it is necessary to use the selenium compounds in rations of domestic animals and poultry. The study of properties and characteristics of selenoproteins is important in discovering selenium role in regulation of cellular growth processes, the protective effect of this element in prevention of toxic action of heavy metals, xenobiotics and bacterial toxins on organism and anticarcinogenic effect of selenium.
