Vitamin B9


Many people, even those far from medicine and biology, know about the role of nucleic acids in the transmission of hereditary traits. The blue eyes of a child, a touching mole that appears with constancy in different generations of the family, character traits, predisposition to diseases and much more is associated with the structure and function of DNA and RNA — two types of nucleic acids responsible for storing and transmitting inherited traits. In the processes that prepare biosynthesis, doubling of nucleic acids, providing cell duplication and tissue growth, the most important role belongs to one of the B vitamins — folic acid. Why is it needed? Sufficient supply of folic acid is of particular importance in the earliest stages of nascent life. In addition to participating in the creation of cells of the nervous system of the fetus, this vitamin is spent on the «repair» and replacement of about 70 trillion mother’s cells, as human cells are constantly updated. Folic acid is necessary for cell division, growth and development of all organs and tissues, normal development of the embryo and fetus, hematopoiesis processes, taking part in the formation of erythrocytes, leukocytes and platelets, i.e. all formed elements of the blood. In this regard, the content of folic acid in the diet of a pregnant woman is also very important. This is especially important in the first trimester of pregnancy, when the main structures of the fetal nervous system are also formed, the correct laying of which is largely provided by folic acid. Sources of Folic acid are rich in the leaves of green plants: spinach, onions, lettuce and other garden greens. Also, this vitamin is found in the liver, kidneys and meat. Folic Acid Deficiency Folic acid deficiency primarily affects the developing nervous system of the fetus. So, with a significant deficiency of the vitamin, the formation of neural tube defects, hydrocephalus, anencephaly (absence of the brain), cerebral hernias is possible, and the risk of mental retardation of the child increases. Folic acid deficiency plays a huge role during pregnancy, since at this time not only the organs and tissues of the fetus are formed, but also the tissue of the placenta, as well as new vessels in the uterus. With a lack of folic acid, this process can be disrupted, which exceeds the likelihood of premature termination of pregnancy. The lack of folic acid also negatively affects the condition of the mother. It can appear in 1-4 weeks, depending on the diet and the previous supply of the vitamin in the body. Early symptoms may include fatigue, irritability, and loss of appetite. Acute deficiency of folic acid derivatives may cause loss of appetite, abdominal pain, nausea and diarrhea, painful mouth and throat ulcers, skin changes and hair loss.
