| DIHYDROFOLIC ACID Usage And Synthesis |
| Uses | antidote to methotrexate toxicity | | Uses | Dihydrofolic Acid is an intermediate in mammalian conversion of dietary folic acid to tetrahydrofolate by dihydrofolate reductase (DHFR). Folic acid (FA) and Dihydrofolic acid (FAH2) are substrates of
dihydrofolate reductase(s) which reduce them to tetrahydrofolate (THF). | | Uses | Dihydrofolic Acid is an intermediate in mammalian conversion of dietary folic acid to tetrahydrofolate by dihydrofolate reductase (DHFR). Folic acid (FA) and Dihydrofolic acid (FAH2) are substrates of dihydrofolate reductase(s) which reduce them to tetrahydrofolate (THF). | | 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. | | 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). | | Purification Methods | DHFA is best purified by suspending (1g mostly dissolved)) in ice-cold sodium ascorbate (300mL of 10% at pH 6.0, prepared by adjusting the pH of 30g of sodium ascorbate in 150mL of H2O by adding 1N NaOH dropwise using a gla |
