Study Notes
Tetrahydrofolate Molecule (THF)
- A component of THF is p-aminobenzoic acid (PABA)
Folic Acid in Protein Synthesis
- Folic acid is essential for one-carbon metabolism, allowing for the synthesis of amino acids, such as methionine and serine
- Folic acid is necessary for the transfer of one-carbon units in amino acid synthesis
Folic Acid Supplementation in Pregnancy
- Folic acid supplementation during pregnancy helps prevent neural tube defects in the fetus
- Supplementation is critical, as the demand for folate increases during fetal development
Antifolates and Metabolic Function
- Antifolates, such as methotrexate, inhibit the action of folic acid, highlighting the importance of folic acid in cell growth and proliferation
- Antifolates are used to treat cancer, as they inhibit the rapid cell division characteristic of cancer cells
Biosynthetic Pathways
- Folate participates in the synthesis of methionine, serine, and glycine
- Folate is essential for the interconversion of amino acids, such as homocysteine and methionine
Antifolates
- Antifolates are known for their ability to inhibit cell growth and proliferation by blocking the action of folic acid
