(6R,S)-5,6,7,8-Tetrahydrofolic acid (THFA), the reduced form of folic acid (Item No. 20515), serves as a cofactor in methyltransferase reactions and is the major one-carbon carrier in one carbon metabolism.1 Its metabolites participate in the synthesis of thymidine for incorporation into DNA or the synthesis of purines, as well as in the formation of methionine, which can be converted to the ubiquitous methyl donor, S-adenosylmethionine (Item No. 13956).1 THFA has also been used to study the activation of metabolite-binding riboswitches.2
