ToggleFunctions of the Vitamin B9
This is vital vitamin which is needed for proper development f the body. It performs following function inside the body.
Function in the DNA and RNA Synthesis
It acts as co enzyme in reactions that involves the synthesis of the DNA and RNA. Basically this vitamin is involved in the synthesis of amino acids which is in turn use for DNA and RNA synthesis.
It is essential when the cell is undergoing rapid division. That is why it is recommended during pregnancy as fetus is going through rapid cell division.
It is also needed when body is going through any healing process as this is also period of rapid cell division. It is also needed during infancy and adolescence.
Function in Red Blood Cells Formation
Folate is also involved in the production of healthy red blood cells, during this process it acts alongside of vitamin B12. When body doesn’t have sufficient supply of vitamin B9 then red blood cells gets deformed. They become enlarged and immature which lead to the megaloblastic anemia.
Prevents Birth Defects
Vitamin B9 is vital for the growth of fetus during 1st trimester of pregnancy. Sufficient supply of folic acid it prevents neural tube defects. (NTDs). It is also needed by the fetus to gain weight. It prevents preterm birth when sufficiently available for the pregnant women.
