Study Notes
Magnesium's Role in the Body
- Magnesium (Mg2+) is a crucial cofactor for over 300 enzymes.
- These enzymes are involved in diverse processes like glycolysis, ion transport, nerve function, and the production of carbohydrates, proteins, lipids, and nucleic acids.
- Magnesium also plays a role in hormone release and response.
Clinical Significance of Serum Mg2+ Levels
- Understanding serum magnesium levels has become more important recently.
- Research has linked abnormal serum Mg2+ levels to various health issues, including cardiovascular, metabolic, and neuromuscular disorders.
- While serum levels may not show the total amount of magnesium in the body, they are helpful in assessing short-term changes in magnesium levels.
