Application

Tetrahydrofolic acid has been used to determine the inhibitory effect of tetrahydrofolate on polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs). A recent use of tetrahydrofolate (THF) is for studying the activation of riboswitches.

Tetrahydrofolic acid may also be used as a standard to generate calibration curve to quantify the folate types produced by Streptococcus thermophilus in milk cultures using high-performance liquid chromatography (HPLC). It is also suitable for use in the enzymatic assay of formate-tetrahydrofolate ligase from M. extorquens (MeFtfL).

Biochem/physiol Actions

Tetrahydrofolic acid is the parent molecule of the folate derivatives that donate one-carbon units to amino acids, nucleic acids, and lipids. Tetrahydrofolate metabolites participate in the synthesis of purine and pyrimidine and in synthesis and conversion of amino acids
