Selenide means that hydrogen selenide dissolved in water can precipitate many heavy metal ions into particles. Selenium and metals in oxidation state +1 can generate two kinds of selenides, namely, positive selenide (m2se) and acid selenide. Selenium is one of the essential trace elements of the human body and organisms. It can regulate the absorption and consumption of vitamins A, C, E, and K. It cooperates with vitamin E to protect cell membranes, and participates in the catalytic reactions of various enzymes in the body. It is an important component of glutathione peroxidase (GSH-Px) and iodothyronine deiodinase (ID).
