Magnesium: Proteins
built 649 days ago
Magnesium ... plays an important role in protein biosynthesis which is certainly applicable to athletes. It is necessary for the activation of amino acids and the attachment of mRNA to the ribosome. This process helps "make" proteins. In other words, protein synthesis depends on optimal magnesium concentrations. It is hypothesized that low magnesium levels may negatively affect protein metabolism, and may result in diminished strength gains in a structured workout regimen. It is important to note that increasing dietary protein intake may increase magnesium requirements because high protein intake may decrease magnesium retention (5).

Magnesium is required for a number of steps during nucleic acid (DNA and RNA) and protein synthesis. Several enzymes participating in the synthesis of carbohydrates and lipids require magnesium for their activity. Glutathione, an important antioxidant, requires magnesium for its synthesis (3).

Magnesium is essential as a cofactor in the synthesis of RNA from DNA. It is important in the synthesis and degradation of DNA, and ... plays a vital role in binding messenger RNA to the 70's subunit of the protein-synthesizing ribosome.
