   Magnesium
   Magnesium is a brilliant white metal, which is relatively soft. It is one of the more abundant elements, there being 23000 ppm in the earth`s crust. As a powder, magnesium is extremely reactive, but as a solid it oxidises slowly in air and reacts slowly in water. It does not occur naturally, but is found in combination with other elements in minera...

   magnesium
   An essential divalent cation. The major role is as the chelated ion in ATP and presumably other triphosphonucleotides. The Mg2+ /ATP complex is the sole biologically active form of ATP. The other essential role of Mg2+ is as the central ion of chlorophyll. Cellular concentration is less than 5mM, serum concentration approx.1mM.
