Elevated levels of homocysteine have been linked to an increased risk of NTDs. Folic acid helps convert homocysteine into other amino acids, reducing its levels in the body.
- Supplementation with folic acid has been shown to significantly reduce the risk of NTDs.
The U.S. Public Health Service recommends that all women of childbearing age consume 400 micrograms of folic acid daily, ideally starting at least one month before conception and continuing throughout pregnancy. This can be achieved through a balanced diet rich in folate-rich foods or by taking folic acid supplements.
By preventing NTDs, folic acid plays a crucial role in ensuring the health and well-being of newborns and their families.
Contributes to DNA Synthesis
DNA synthesis is the process by which cells make copies of their genetic material. This process is essential for cell division, growth, and repair. Folic acid plays a crucial role in DNA synthesis by acting as a cofactor for several enzymes involved in this process.
- Folic acid is required for the synthesis of thymidine, one of the four building blocks of DNA.
Thymidine is produced from uridine, another nucleotide, in a reaction catalyzed by the enzyme thymidylate synthase. Folic acid is a cofactor for thymidylate synthase, meaning it is required for the enzyme to function properly.
- Folic acid is also involved in the synthesis of purines, another type of nucleotide.
Purines are synthesized from a precursor molecule called inosine monophosphate (IMP). Folic acid is a cofactor for the enzyme that converts IMP to adenosine monophosphate (AMP), the first step in the purine synthesis pathway.
- In addition to its role in nucleotide synthesis, folic acid is also involved in the repair of damaged DNA.
When DNA is damaged, it can be repaired through a process called base excision repair. Folic acid is a cofactor for the enzyme that removes the damaged base from DNA, allowing it to be replaced with a new one.
- By contributing to DNA synthesis and repair, folic acid plays a vital role in maintaining the integrity of the genetic material and ensuring the proper functioning of cells.
This is particularly important during periods of rapid growth and development, such as in embryos, infants, and children.
Overall, folic acid is an essential nutrient for DNA synthesis and repair, contributing to the health and well-being of individuals throughout their lifespan.
