Description

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.

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).

Packaging

Sealed ampule.
