Deficiency of the vitamin … WebFolate and vitamin B12 are required for biological methylation and DNA synthesis. Vitamin B12 also participates in the mitochondrial catabolism of odd-chain fatty acids and some amino acids. Inborn errors of their metabolism and severe nutritional deficiencies cause serious neurological and hematological pathology.
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. WebSep 25, 2024 · ABSTRACT. Folate-mediated one-carbon metabolism (FOCM) is compartmentalized within human cells to the cytosol, nucleus, and mitochondria.
