ANALYSIS OF RESEARCH RESULTS OF SELENIUM CONTENT IN VEGETABLE RAW MATERIALS

doi: 10.25712/ASTU.2072-8921.2021.03.009

Abstract

The trace element selenium is a necessary nutrient for the normal functioning of the human body. Compounds of this trace element protect cell membranes from oxidative destruction, catalyze intermediate reactions in metabolism, and reduce the toxicity of some heavy metals. Vitamins C and E together with selenium enhance their antioxidant properties and effectively prevent oxidation in cells and tissues. In addition, selenium is able to protect nucleic acids from damage. This trace element is unevenly distributed in different regions of the world. The average content of selenium in the earth's crust, expressed as a percentage as a clarke number, is 5 · 10¯6.

The biological activity of selenium depends on the chemical form in which it is found in food and the body. Inorganic forms of selenium are more toxic than organic ones. Therefore, organic forms of selenium are used to prevent selenium deficiency conditions.
