WebApr 11, 2024 · This is a key step in the pathway for the THF regeneration, which allows for DNA synthesis by thymidylate synthesis and for folate delivery to body tissues [125,126,131,133]. Therefore, cobalamin deficiency can lead to the absence of demethylation of methyltetrahydrofolate, resulting in folate deficiency subsequently as well. WebFolate is a water soluble vitamin (B9) that is essential for DNA synthesis and repair, myelination (e.g. insulation around neurons), and production of neurotransmitters such as serotonin. These processes are essential for a healthy brain. Our DNA, which provides the instructions to our neurons, can become damaged and is consistently being repaired.
