What is Methylenetetrahydrofolate Reductase (MTHFR)?
Methylenetetrahydrofolate reductase (MTHFR) is an enzyme that plays a crucial role in the metabolism of folate and the regulation of homocysteine levels in the body. It catalyzes the reduction of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate, which is a key step in the conversion of homocysteine to methionine.
