COM to make DNA and normal red blood cells, and the growing fetus must have it for the proper development of the nervous system. Bacteria must also have folic acid so they can carry out important functions within the cell. Bacteria can make folic acid, however, while people cannot. Folic acid and folate (MPKB) - is converted by the body into DHFR (DiHydro-Folate Reductase), which can be used by parasitic bacteria to form the Isn 39;t it strange that while we give these folks medicines which block their folic acid metabolism, we pour folic acid down nbsp; Targeting Bacterial Central Metabolism for Drug Development or inhibit their growth.
