Vitamins B1, B2, B3, B6, B9, B12 THEIR VALUES AND FUNCTIONS:

• Vitamin B1 (thiamine) is mainly involved in the metabolism of carbohydrates, in the body it is converted into cocarboxylase. REQUIRED FOR NORMAL ACTIVITY OF THE CENTRAL NERVOUS SYSTEM. REGULATOR OF FAT AND CARBON METABOLISM
• .Vitamin B2 (riboflavin) plays an important role in protein metabolism, it is also involved in carbohydrate and fat metabolism. PARTICIPATE IN REDOX REACTIONS
• VITAMIN B3 (PANTOTENIC ACID) PARTICIPATES IN THE REACTIONS OF BIOCHEMICAL ACYLATION, METABOLISM OF PROTEINS, LIPIDS, CARBOHYDRATES
• Vitamin B6 (pyridoxine) is essential for protein metabolism and building diversity. It has a regulatory effect on the nervous system, participates in hematopoiesis, improves lipid metabolism in atherosclerosis, enhances the secretion of gastric juice. Thiamine is contained in the germs and shells of oats, buckwheat, wheat, in bread baked from plain flour. Especially a lot of it in yeast. ALSO PARTICIPATES IN THE METABOLISM SYNTHESIS OF AMINO ACIDS, FATTY ACIDS AND UNSATURATED LIPIDS.
• Vitamin B9 (folic acid) is essential for the proper functioning of vitamin B12 in the production of red blood cells and the processing of carbohydrates, fats and proteins. PARTICIPATES IN THE SYNTHESIS OF AMINO ACIDS, CHOLINE ETC.
• Vitamin B12 (cyanocobalamin) is essential for normal blood formation. It is involved in protein metabolism, has a positive effect on fat and carbohydrate metabolism, on the function of the nervous system and liver. Vitamin B12 lowers blood cholesterol and activates the blood coagulation system. With a lack of vitamin B12, anemia develops.

Slide 7

Vitamin B1, B2, B6 deficiency:

• B-1. With a lack of thiamine, there is a breakdown, increased fatigue, tachycardia
• With a lack of vitamin B2, weakness is noted, appetite and weight decrease, the process of hematopoiesis is disturbed, pain in the eyes, cracks and pain appear.
• With a lack of vitamin B6, gastrointestinal disorders are observed, skin lesions and neuropsychiatric disorders are noted. For example, if you suddenly experience "hell pain" in the back of your ankle at night, so severe that you jump out of bed, you can assume that you are not getting enough vitamin B6 (but this can also be a sign of a lack of vitamin E or magnesium. in the hands, twitching of the eyelids, you sleep badly, you have a bad memory - these are not signs of old age at all.

Slide 8

Lack of vitamin B9, B12:

• Signs of a lack of folic acid (vitamin B9): depression, fatigue, insomnia, irritability, forgetfulness, weakness, pallor, inflammation of the gums, sometimes neuralgic pain (especially in older people
• Vitamin B12 lowers blood cholesterol and activates the blood coagulation system. With a lack of vitamin B12, anemia develops, severe disorders.

Folic acid (lat. acidum folicum, folacin; from lat. folium leaf) is a water-soluble vitamin B 9 necessary for the growth and development of the circulatory and immune systems. Along with folic acid, vitamins include its derivatives, including di-, tri-, polyglutamates and others. All such derivatives, together with folic acid, are combined under the name folacin.lat. circulatory immune system vitamins

Discovery History In 1931, researcher Lucy Wills reported that taking a yeast extract helped cure anemia in pregnant women. This observation led researchers in the late 1930s to identify folic acid as the main active ingredient in yeast. Pholic acid was obtained from spinach leaves in 1941 and was first chemically synthesized in Lucy Wills yeast extract of anemia spinach.

Biological significance From the lack of folic acid, the bone marrow suffers, in which there is an active division of cells. Progenitor cells of red blood cells, formed in the bone marrow, increase in size in folic acid deficiency, forming the so-called megaloblasts and leading to megaloblastic anemia.

Daily Value Adults mcg Pregnant women mcg Breastfeeding women mcg Children up to 300 mcg per day

Hypovitaminosis Rarely develops, mainly in violation of its absorption by the body. Symptoms of hypovitaminosis: red tongue, anemia, apathy, fatigue, insomnia, anxiety, indigestion, graying, growth retardation, shortness of breath, memory problems, birth defects of offspring. With a deficiency of folic acid in a pregnant woman, the likelihood of developing toxicosis, depression increases, pain in the legs appears, and anemia of pregnant women develops.

Hypervitaminosis Large doses of folic acid sometimes cause dyspepsia in children, an increase in the excitability of the central nervous system, and can lead to hypertrophy and hyperplasia of the epithelial cells of the kidneys. Long-term use of large doses of folic acid is not recommended due to the possibility of a decrease in the blood concentration of vitamin B12.

GENERAL INFORMATION ON THE ACTION OF FOLIC ACID: Pholic acid takes an active part in the processes of regulation of the functions of the hematopoietic organs, has an antianemic effect in macrocytic anemia. Pholic acid affects the functions of the intestines and liver, increases the content of choline in the liver and prevents its fatty infiltration. Pholic acid supports the immune system by contributing to the normal formation and function of white blood cells. Pholic acid plays an important role in pregnancy. It regulates the formation of embryonic nerve cells, which is extremely important for normal development. Daily intake of folic acid in early pregnancy can prevent fetal nerve trunk defects such as anencephaly and spina bifida in 75% of cases. In addition, folic acid prevents premature birth, premature birth and premature rupture of the amniotic membrane. Folic acid is indispensable for relieving postpartum depression, so it can rightfully be called the most important female vitamin. In high doses, folic acid has an estrogen-like effect, it can delay the onset of menopause and alleviate its symptoms, and in adolescent girls, it can correct delayed puberty.
