MTHFR: 4 Things to Consider Before Taking Folate

WebA folate analog, methotrexate, is an anti-tumor, chemotherapeutic agent that acts by inhibiting dihydrofolate reductase. Deoxythymidine monophosphate (dTMP) is synthesized by the addition of a methyl group to deoxyuridine monophosphate (dUMP). dTMP is subsequently phosphorylated to the triphosphate form (dTTP) and used for DNA synthesis. mccullough high school the woodlands txWebFolate is a B-vitamin naturally found in some foods.
