Answer:

Cyanocobalamin is the chemical name for Vitamin B12. Vitamin B12 is a water-soluble vitamin that plays a crucial role in various bodily functions, including the formation of red blood cells, DNA synthesis, and proper functioning of the nervous system.

Explanation:

1. Cyanocobalamin:
- Cyanocobalamin is the synthetic form of Vitamin B12. It is the most stable and commonly used form of Vitamin B12 in supplements and fortified foods.
- The name "cyanocobalamin" refers to the presence of a cyanide molecule attached to the cobalamin structure.
- Cyanocobalamin is converted to its active forms, methylcobalamin and adenosylcobalamin, in the body.

2. Vitamin B12:
- Vitamin B12 is essential for the normal functioning of the body. It is involved in various biochemical reactions and processes.
- It is primarily obtained from animal sources such as meat, fish, eggs, and dairy products. However, it can also be obtained from fortified plant-based foods or supplements for individuals following a vegetarian or vegan diet.
- The recommended daily intake of Vitamin B12 varies depending on age, sex, and specific health conditions.
- Vitamin B12 deficiency can lead to various health problems, including anemia, neurological disorders, and impaired cognitive function.

3. Functions of Vitamin B12:
- Formation of red blood cells: Vitamin B12 is necessary for the production of healthy red blood cells. It is involved in the synthesis of DNA and the growth and division of cells within the bone marrow.
- Nervous system function: Vitamin B12 plays a crucial role in maintaining the health of the nervous system. It helps in the production of myelin, a protective coating around nerve fibers that allows for proper nerve signaling.
- DNA synthesis: Vitamin B12 is involved in the synthesis of DNA, the genetic material in all cells. It helps in the proper replication and repair of DNA.
- Energy production: Vitamin B12 is involved in the metabolism of macronutrients, including carbohydrates, fats, and proteins. It helps convert these nutrients into usable energy for the body.

Conclusion:
In conclusion, cyanocobalamin is the chemical name for Vitamin B12. Vitamin B12 is an essential nutrient that plays a crucial role in various bodily functions, including the formation of red blood cells, DNA synthesis, and proper functioning of the nervous system. It is important to ensure an adequate intake of Vitamin B12 through diet or supplementation to maintain optimal health.
