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

Folic Acid Metabolism in Cancer

This issue of Biofiles reviews some of our newest and most innovative technologies and their specific applications toward cancer research. In preparing this issue of Biofiles, one is reminded how complex the disease of cancer is, and how difficult it is to identify one topic that is completely unrelated to any other.
