Magnesium: Energy
built 650 days ago
Magnesium is an important ion in all living cells being a cofactor of many enzymes, especially those utilising high energy phosphate bounds. The relationship between insulin and magnesium has been recently studied. In particular it has been shown that magnesium plays the role of a second messenger for insulin action; on the other hand, insulin itself has been demonstrated to be an important regulatory factor of intracellular magnesium accumulation. Conditions associated with insulin resistance, such as hypertension or aging, are ... associated with low intracellular magnesium contents. In diabetes mellitus, it is suggested that low intracellular magnesium levels result from both increased urinary losses and insulin resistance. The extent to which such a low intracellular magnesium content contributes to the development of macro- and microangiopathy remains to be established.

Magnesium is an essential cofactor in the transfer of a high energy phosphate group from phosphoenol pyruvate to adenosine pyrophosphoric acid (ADP), synthesizing adenosine triphosphate (ATP). This is an important energy-producing step in glycolysis.

Magnesium is essential for every major biological process. It is necessary for the metabolism of glucose, production of cellular energy, and the synthesis of nucleic acids and proteins.* Magnesium's role in cellular reproduction is key in maintaining healthy levels of immune-related cells during an immune challenge.*

Magnesium is important as a cofactor for enzymes that convert adenosine triphosphate (ATP) to adenosine pyrophosphoric acid (ADP), with the subsequent release of energy. As a constituent of these enzymes, magnesium is essential to reactions involving the synthesis and metabolism of carbohydrates, lipids, proteins, and nucleic acids.
