Anwendungen & Verwendung
Beschreibung
Anhydrous Magnesium Acetate has the chemical formula Mg(CH3COO)2 and in its hydrous form, Magnesium Acetate Tetrahydrate, it has the chemical formula Mg(CH3COO)2.4H2O. In this compound the magnesium metal has an oxidation state of 2+. Magnesium acetate is the magnesium salt of acetic acid.It is deliquescent and upon heating, it decomposes to form magnesium oxide.Magnesium acetate is commonly used as a source of magnesium or as a chemical reagent.
Verwenden
Dye fixative in textile printing, deodorant, disinfectant, and antiseptic. Magnesium acetate is used in chemistry and molecular biology as a reagent and a source of magnesium. Magnesium has a variety of biological roles in enzymology, cell membrane and wall structural integrity, muscle cell physiology, and nucleic acid structure.Magnesium is an essential co-factor in many enzymes, including deoxyribonuclease (DNase), the restriction enzymes EcoR I and EcoR V, and Ribonuclease H. Magnesium also stabilizes polymeric nucleic acids such as transfer RNA and ribozymes. Magnesium acetate has been widely used in the crystallization of proteins. A protocol for the separation of MB and BB isoenzymes of creatine kinase and the LD1 isoenzyme of lactate dehydrogenase that involves elution with magnesium acetate has been published.
