Abstract
Tetrahydrofolate (THF) is the metabolically active form of folate that is central to normal one-carbon metabolism. The interdependent and interconnecting pathways of folate and one-carbon metabolism are graphically presented in Fig. 1 with emphasis on the two major functions of folic acid: DNA synthesis and DNA methylation. Normal folate metabolism is essential for the synthesis and balance of deoxynucleotide triphosphate (dNTP) precursor pools required for error-free DNA synthesis and repair (1).
