Identification
- Generic Name
- Tetrahydrofolic acid
- DrugBank Accession Number
- DB00116
- Background
Tetrahydrofolic acid is a folic acid derivative that is produced from dihydrofolic acid after conversion by dihydrofolate reductase. It is converted into 5,10-methylenetetrahydrofolate by serine hydroxymethyltransferase. It is a soluble coenzyme in many reactions, especially in the metabolism of amino acids and nucleic acids.

Tetrahydrofolate is the main active metabolite of dietary folate. It is vital as a coenzyme in reactions involving transfers of single carbon groups. Tetrahydrofolate has a role in nucleic and amino acid synthesis. As nucleic and amino acid synthesis is affected by a deficiency of tetrahydrofolate, actively dividing and growing cells tend to be the first affected. Tetrahydrofolate is used to treat topical sprue and megaloblastic and macrocytic anemias, hematologic complications resulting from a deficiency in folic acid.
- Mechanism of action
Tetrahydrofolate is transported across cells by receptor-mediated endocytosis where it is needed to maintain normal erythropoiesis, synthesize purine and thymidylate nucleic acids, interconvert amino acids, methylate tRNA, and generate and use formate.
