Functions of magnesium
Magnesium is the second most abundant intracellular cation and has a vital role in a range of biochemical and physiological processes . Magnesium helps stabilize ATP by binding to the phosphate groups of this molecule. In fact, magnesium is required by more than 300 enzymes that utilize ATP, including those required for energy metabolism , muscle contraction, and protein synthesis. A magnesium-dependent enzyme system pumps sodium out of cell and potassium into cell-this process seems especially sensitive to magnesium deficiency. Magnesium also is needed for DNA and RNA synthesis . It's in calcium metabolism contributes to bone structure and mineralization . Magnesium also important for nerve transmission , heart and smooth muscle contraction, and glucose and insulin metabolism . Research suggests the diets high in magnesium-rich foods may help protect against Metabolic Syndrome and diabetes by improving insulin action . Other possible benefits of magnesium include decreasing blood pressure by dilating arteries, preventing heat rhythm abnormalities, and protecting against gallstone formation.
