Review[Biological function of some elements and their compounds. II. Selenium, selenate, selenium organic compounds].
The review is devoted to the role of selenium and its compounds for living organisms. Selenium as an antioxidant protects the cells from generating free radicals. It constitutes an integral part of approximately 20 enzymes. ⋯ Amino acid bonds are significant in functions of RNA, in biosynthesis and activity of thyroid hormones. Selenium deficiency leads to decrease in selenium-dependent glutathione peroxidase, which occurs in mitochondria and cytosole. It causes also heart muscles diseases, the skeletal and circulatory systems disorders, neoplasms, infections, and cold.
