Hydrogen selenide

Description

Hydrogen selenide, also known as selenide, belongs to the class of inorganic compounds known as homogeneous other non-metal compounds. These are inorganic non-metallic compounds in which the largest atom belongs to the class of 'other non-metals'. Hydrogen selenide is a drug. Hydrogen selenide is possibly neutral. Hydrogen selenide exists in all living organisms, ranging from bacteria to humans. According to the Sonoda method, H2Se is generated from the reaction of H2O and CO on Se in the presence of Et3N. Within humans, hydrogen selenide participates in a number of enzymatic reactions. In particular, L-alanine and hydrogen selenide can be biosynthesized from selenocysteine; which is mediated by the enzyme selenocysteine lyase. In addition, hydrogen selenide can be converted into phosphoroselenoic acid; which is mediated by the enzyme selenide, water dikinase 2. In humans, hydrogen selenide is involved in selenoamino acid metabolism. Hydrogen selenide is a potentially toxic compound. Even at extremely low concentrations, this compound has a very irritating smell resembling that of decayed horseradish or 'leaking gas', but smells of rotten eggs at higher concentrations. H2Se is a colorless, flammable gas under standard conditions. H2Se + SO2 ⇌ 2 H2O + 2 Se + SIts decomposition is used to prepare the highly pure element.
