Abstract

Despite the major advances of magnesium research during the past 20 years, there is still much to be learned about the mechanism of action of magnesium cations in the many chemical and biological processes in which the water molecules are intimately involved. Very little systematic study has been conducted of magnesium chemicals that may inhibit or prevent cancer. The effect of counter anion also has not been studied to its basic considerations and magnesium ions in cardiovascular cells. The supramolecular chemistry of magnesium in biological systems is the starting point of description of the chemistry and biochemistry of magnesium. Magnesium ions are present in all cells and in all reactions in which ATP is a substrate (Mg2+.ATP)[1]. In this substrate complex, Mg2+ is chelated between the phosphates β and γ and is capable of approaching and bind in a reversible fashion to other sites of specific proteins. However, its precise function in the specific cleavage of the terminal phosphoryl group of the ATP molecule is still unknown [2]. In addition, it intervenes in all the nucleic acid syntheses, in nucleotides or lipids and glucides and in the activation of muscular contraction. This cleavage involves hydrolysis of ATP to ADP and Pi and Mg2+ is known to be essential for this dephosphorylation. The hydrolysis of ATP at the Pγ position has not been determined clearly. It proceeds through the attack of nucleophiles, such as OH− and H2O on the Pγ
