Folate pathway bacteria
WebFolate (vitamin B9), is an essential nutrient which acts as a coenzyme in one-carbon metabolism. It is important for normal fetal development. It also plays an important role for the methionine cycle, which is required for normal cellular functions and necessary for DNA replication (Sharp, 2005; Mahan and Escott-Stump, 2008). The biological activity of folate in the body depends upon dihydrofolate reductase action in the liver which converts folate into tetrahydrofolate (THF). This action is rate-limiting in humans leading to elevated blood concentrations of unmetabolized folic acid when consumption from dietary supplements and fortified foods nears or exceeds the U.S. Tolerable Upper Intake Level of 1,00…
