What is folic acid pathway?
Folic acid is synthesized by bacteria from the substrate, para-amino-benzoic acid (PABA), and all cells require folic acid for growth. Folic acid (as a vitamin in food) diffuses or is transported into mammalian cells. However, folic acid cannot cross bacterial cell walls by diffusion or active transport.
What metabolic pathways use folate?
The biochemical outputs of folate metabolism include nucleotide synthesis, serine-glycine interconversion, mitochondrial tRNA modification, and methyl group biogenesis, which in turn supports cellular functions such as proliferation, mitochondrial respiration, and epigenetic regulation.
What is the role of folic acid in metabolism?
Folic acid is necessary for cell development; for the metabolism of specific biochemical reactions in the body, such as the conversion of homocysteine to methionine; and for the metabolism of specific anticonvulsant drugs. Folic acid has an interrelationship with vitamin B12.
What is the role of folic acid in DNA synthesis?
Folate has an essential role in one-carbon metabolism and is a strong antiproliferative agent. Folate increases DNA stability, being crucial for DNA synthesis and repair, the methylation cycle, and preventing oxidation of DNA by free radicals.
Does folic acid boost metabolism?
In humans, high erythrocyte folate status during pregnancy was associated with increased fat mass of children at six years of age [22]. Folic acid appears to influence energy and lipid metabolism by modulating DNA methylation and gene expression patterns [17,18,23].
Does folic acid get converted to folate?
Folate is a water-soluble B vitamin that is naturally present in some foods, added to others, and available as a dietary supplement. Folic acid is the fully oxidized monoglutamate form of the vitamin that is used in fortified foods and most dietary supplements.

How does folic acid help neural tube formation?
Folate is effective in preventing neural tube defects So, folate-deficient situations are easy to occur in neuroepithelial cells, where large amounts of folate are needed to make nuclei acids, resulting in NTDs. Thus, folate is effective to prevent NTDs.
Is pantothenic acid an amino acid?
Pantothenic acid (vitamin B5) is also known as pantothenate, and is formed from beta alanine (an amino acid) and pantoic acid (an alpha hydroxyl acid).
Does folic acid block folate receptors?
Folic acid blocks the uptake of methylfolate into the brain via inhibition of folate receptors.
How is folic acid excreted?
Excess folic acid is excreted in urine. A high folate intake can mask vitamin B-12 deficiency until its neurological effects become irreversible. This can typically be remedied by taking a supplement containing 100 percent of the daily value of both folic acid and vitamin B-12.
How does folate affect neural tube?
The most common forms of neural tube defects are spina bifida and anencephaly. Folate deficiency increases the risk of neural tube defects, and inadequate concentrations of folate in a pregnant woman can therefore lead to the development of a fetus with congenital defects and malformations.
