Vitamin B9 (Folate)
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 (see De Novo Purine Synthesis & Pyrimidine Synthesis). Folate is present in leafy green vegetables, and it is absorbed in the jejunum of the small intestine.
