Application

Dihydrofolic acid has been used in diaphorase-coupled assay for dihydrofolate reductase (DHFR) activity. It has also been used as a component in assay buffer to determine dihydrofolate reductase (DHFR) activity.

Biochem/physiol Actions

Folic acid (FA) and dihydrofolic acid (FAH2) are substrates of dihydrofolate reductase(s) which reduce them to tetrahydrofolate (THF), which in turn supports ‘;one carbon’; transfer. Tetrahydrofolates are required for de novo synthesis of purines, thymidylic acid and various amino acids and for post-translational methylation (epigenetics).

General description

Intermediate in mammalian conversion of dietary folic acid to tetrahydrofolate by dihydrofolate reductase (DHFR). In bacteria, dihydrofolic acid is generated from 7,8-dihydropteroate by dihydrofolate synthetase.
