Name: Dihydrofolic acid
Description:Dihydrofolic acid is a folic acid derivative acted upon by dihydrofolate reductase to produce tetrahydrofolic acid. It interacts with bacteria during cell division. It can be targeted with drug analogs to prevent nucleic acid synthesis. Dihydrofolic acid is also known by the name Dihydrofolate - more commonly Vitamin B9.
