Mechanism
Synthesis from 2 studies
Your body needs B vitamins to break down sugar and make ATP, the molecule that stores energy. But ATP can't do anything unless magnesium is attached to it — like a key that only works when inserted into its lock. Without magnesium, even plenty of ATP won't power your cells.
Most probable mechanism
Magnesium binds to ATP, turning it into a form that cells can actually use to power reactions like breaking down sugar for energy. Without magnesium, ATP is just a molecule that can't do its job. B vitamins help move sugar through the energy-making pathway so that ATP can be made in the first place.
Magnesium ions bind to ATP to form a stable Mg-ATP complex that is the only biologically active form capable of donating phosphate groups in enzymatic reactions.
The Mg-ATP complex serves as the direct substrate for energy-requiring enzymes, including those involved in glycolysis and ATP synthesis, enabling phosphate transfer and conformational changes necessary for metabolic function.
B vitamins act as precursor molecules for coenzymes that facilitate key steps in glycolysis, allowing the conversion of glucose into pyruvate and the net production of ATP.
The ATP generated through glycolysis must be complexed with magnesium to be utilized in downstream processes such as muscle contraction, ion pumping, and biosynthesis.
