Vitamin B12 (Vitamin B12), Cyanocobalamin (Suapocobalamin) - a B vitamin. This vitamin has coenzyme activity in the form of 5-deoxyadenosyl cobalamin (5-deoxyadenosyi cobalamin); it is necessary for the synthesis of nucleic acids, maintaining normal myelin and the absorption of another B vitamin by the body - folic acid. Vitamin B12 can be absorbed only if there is a specific protein in the body - internal factor (intrinsic factor), which is produced by the glands of the stomach.
Vitamin B12 deficiency causes changes in almost all organs and tissues, especially in those whose cells are actively multiplying. The most serious manifestations of deficiency of this vitamin include pernicious anemia and degenerative changes in the nervous system.
Vitamin B12 is produced only by certain microorganisms and is found exclusively in foods of animal origin. It is found in large quantities in liver, fish and eggs. The recommended daily intake of this vitamin for adults is 34 mcg.
Vitamin B12 (cyanocobalamin): an important coenzyme and essential nutrient
Vitamin B12, also known as cyanocobalamin, is one of the eight B vitamins. It plays an important role in a variety of biological processes and is essential for maintaining a healthy body. Vitamin B12 has the activity of a coenzyme known as 5-deoxyadenosyl cobalamin, which is an integral part of many enzymatic reactions.
One of the key functions of vitamin B12 is its role in the synthesis of nucleic acids, including DNA, RNA and methylated biologically active substances. Vitamin B12 is also necessary for the normal functioning of the nervous system and the maintenance of healthy myelin, a substance that protects nerve fibers. In addition, it plays an important role in the absorption of another B vitamin - folic acid, which is also necessary for normal DNA formation and the production of new cells.
The absorption of vitamin B12 by the body is possible only in the presence of a specific protein known as intrinsic factor. This factor is produced by the glands of the stomach and helps the absorption of vitamin B12 in the small intestine. Intrinsic factor deficiency or dysfunction can lead to vitamin B12 deficiency, which can have serious health consequences.
Vitamin B12 deficiency can cause a variety of changes in organs and tissues of the body, especially in those where cells actively multiply. One of the most serious manifestations of vitamin B12 deficiency is pernicious anemia, which is characterized by a lack of mature red blood cells in the blood due to a violation of their formation. Vitamin B12 deficiency can also lead to degenerative changes in the nervous system, resulting in symptoms such as numbness, weakness, problems with coordination and memory.
Vitamin B12 is synthesized only by certain microorganisms and is not synthesized by the human body itself. It is found exclusively in animal products such as liver, meat, fish, eggs and dairy products. Vegetarians and vegans who exclude these foods from their diet are advised to consider alternative sources of vitamin B12, such as fortified foods or dietary supplements.
The recommended daily intake of vitamin B12 for adults is about 34 mcg. However, individual needs may vary depending on gender, age, physiological state and nutritional characteristics. If you are deficient in vitamin B12, it is recommended that you consult a doctor or dietitian to evaluate your diet and, if necessary, take additional measures such as taking supplements or changing your diet.
In conclusion, vitamin B12 is an essential nutritional element required for many biological processes in the body. It plays a key role in nucleic acid synthesis, maintaining a healthy nervous system and folic acid absorption. Vitamin B12 deficiency can have serious health consequences, so it is important to ensure adequate intake through a varied and balanced diet that includes animal products or alternative sources of vitamin B12.
Vitamin B12, also known as cyanocobalamycin, is an essential B vitamin that plays an important role in the synthesis of DNA and RNA in cells. It has many functions in the body, including participation in homocysteine metabolism, immune system function, appetite regulation, and even heart and vascular health. Below we will look at the main aspects of the chemical composition and physiology of vitamin B12, its properties and symptoms of deficiency.
Chemical composition of vitamin B12: Vitamin B12 in its structure is a group of coenzymes that are necessary for a number of enzymatic reactions in various tissues of the body. The vitamin itself contains a complex of cobalt and adenosine, which gives it its blue color, which is why it is called cyanocobalmin. One gram of cyanocobalamin contains approximately 6 mcg of vitamin B12. Vitamin B12 deficiency is called megaloblastic anemia. It causes a decrease in the number of red blood cells, accompanied by severe fatigue. Patients may suffer from poor tissue regeneration, but live long enough. A lack of vitamin B12 can also cause problems with the nervous system. People who are deficient may develop damage to the peripheral nervous system, as well as more severe consequences such as Wernicke-Korsakoff encephalopathy, impaired consciousness, peripheral nerve inflammation, and cerebellar ataxia. Thinning gums may also occur, leading to cracked teeth and an itchy base of the tongue. Thyroid diseases of varying severity often develop.
