General magnesium-dependent enzymatic and cellular processes

Magnesium is an essential divalent cation that serves as a mandatory cofactor for over 300 enzymatic reactions within the human body (StatPearls, 2023). It is fundamentally involved in energy production through the stabilization of ATP, as well as in the synthesis of DNA, RNA, and proteins (NIH ODS, 2022). Magnesium-dependent processes are critical for maintaining normal muscle and nerve function, cardiac rhythm, and bone integrity. Clinically, magnesium salts are used to treat conditions like preeclampsia, eclampsia, and certain arrhythmias (PubChem, 2024). Chronic magnesium deficiency is associated with an increased risk of hypertension, type 2 diabetes, and osteoporosis. Because this entry describes a broad set of physiological mechanisms rather than a single protein or receptor, it is classified as a general biological process rather than a specific therapeutic target. The regulation of these processes is managed by various transporters and channels that maintain intracellular magnesium homeostasis.

Magnesium acts as a divalent cation cofactor that stabilizes the structure of ATP and nucleic acids, facilitates phosphate transfer in kinase reactions, and modulates ion channel gating (StatPearls, 2023).
