What is the role of folic acid in my body

Folic acid (vitamin B9) is a water-soluble B group vitamin. It is present in foods as folate and in supplements as folic acid, which has greater bioavailability. Folate plays an essential role in DNA synthesis and repair, and in cell growth and division. Folate also has a major role in DNA methylation and is therefore important for epigenomic regulation.

Folic acid plays a critical role in ..

In B12 deficiency, inadequate DNA synthesis seems due in large measure to a block of tetrahydrofolic acid (THFA) regeneration from 5-methyl THFA (via homocysteine transmethylation).

In support of the above, homocysteine appears to facilitate and methionine to reduce de novo DNA synthesis. This was measured by the ability of deoxyuridine to suppress thymidine-3H uptake into DNA in human bone marrow cultures. The homocysteine effect in B12-deficient marrow supports the possibility that there is in man an additional B12-independent pathway for regeneration of THFA by methylation of homocysteine to form methionine.

In addition, there is a multiple cross over inhibition and activation of all dNTP molecules promoting the even synthesis of DNA precursors.

(remember that folic acid is required for thymine synthesis ..

But genes are not found only in reproductive cells. Every cell in an organism contains DNA (and therefore genes) because DNA also codes for the proteins that the organism produces. And proteins control cell function and provide structure. So, the basis of life happens in each and every cell.

Among possible explanations for the methionine effect is end-product inhibition of the homocysteine transmethylase reaction, resulting in further accumulation of 5-methyl THFA. Homocysteine transmethylation may play an important role in the regulation of THFA availability and de novo DNA synthesis.

Folic acid is a water-soluble B vitamin with a role as a ..

The order of the nitrogenous bases on a strand of DNA (or in a section of the DNA that comprises a gene) determines which amino acid is produced. And the order that amino acids are strung together determines which protein is produced. Which protein is produced determines what structural element is produced within your body (such as, muscle tissue, skin, or hair) or what function can be performed (such as if hemoglobin is being produced to transport oxygen to all the cells).

Despite overwhelming evidence that folic acid fortification is effective in reducing NTDS, a significant proportion of women remain folate-deficient in early pregnancy. Health Canada and the Public Health Agency of Canada recommend that women of child-bearing years take a daily supplement of 0.4 mg of folic acid to reduce the risk of NTDs. This recommendation is supported by detailed guidelines from the Society of Obstetricians and Gynaecologists of Canada. They recommend that women in good health eat a diet of folate-rich foods, along with daily supplementation with a multivitamin which includes folic acid (0.4 mg to 1.0 mg) for at least two to three months before conception and throughout the pregnancy and postpartum periods (for a minimum of four to six weeks and as long as breastfeeding continues). Factors known to increase the risk of NTDs in subsequent pregnancies include birth of a previous child with a NTD, a family history of NTDs, maternal obesity and maternal Hispanic origin, and the use of some anticonvulsants. Pregestational or gestational diabetes is of low predictive value, perhaps because the risk may vary with the level of glycemic control. Since the etiology appears to be multifactorial, each risk factor is of similarly low predictive value, with the highest risk being for women with a previous affected child (at 2% to 5% before fortification ). Therefore, for women with a family history of NTD or other health complications, the SOGC recommends increasing dietary intake of folate-rich foods and daily supplementation with multivitamins (including 5 mg of folic acid) at least three months before conception and continuing 10 to 12 weeks postconception.
