Summary
Vitamin B9 (Folate) is a water-soluble vitamin that plays a key role as a component of THF (tetrahydrofolate). THF serves a key role in methylation reactions, such as those required for DNA and RNA synthesis. Folate is present in leafy green vegetables, and it is absorbed in the jejunum of the small intestine.
