Folic acid (vitamin b9) is transformed into a tetra hydro folic acid (THFK, FH4) in the tissues, which can be called coenzyme.
This vitamin is involved in the biosynthesis of nitrogen bases, nucleic acids (and thus in the synthesis of DNA), creatine, methionine and serine amino acid.
The studies, which were conducted after the 1970s have shown that pre-cancerous cells can be protected if folic acid is consumed in large quantities.
Folic acid has a role (along with vitamin B12) in the protection of various forms of cancer, especially lung cancer.
Vitamin B9 is needed for the formation of red blood cells and plays an important role in the prevention of birth defects.
The body folic acid is deposited in the liver and is excreted by urine.
