Question

What is the chemical name of the vitamin${{B}_{12}}$.
A) Riboflavin
B) Thiamin
C) Cyanocobalamin
D) Pyridoxine

Answer 1

It is a coordination complex which is very essential for healthy living.
In Vitamin ${{B}_{12}}$, Co is the central metal atom.

Complete step by step answer:
So in the question it is given that we have to give the chemical name for vitamin ${{B}_{12}}$
Vitamin ${{B}_{12}}$ is a type of vitamin B, which is necessary for many of the life processes.
In vitamin ${{B}_{12}}$, the rare element Cobalt ($Co$) is present as the central atom, in the centre most part of a corrin ring. And hence the chemical name of vitamin ${{B}_{12}}$ is generally called cobalamin. And it exists in mainly four nearly identical forms. They are hydroxocobalamin, cyanocobalamin, methylcobalamin and adenosylcobalamin.
Vitamin ${{B}_{12}}$ is having the most complex structure.
It is a water –soluble structure and only produced by some type of bacteria. Vitamin ${{B}_{12}}$ is a cofactor in the DNA synthesis and in fatty acids and amino acid metabolism. It helps the body to produce red blood cells and it keeps the nervous system of the body healthy. It helps to release the energy from the food.
The deficiency of vitamin ${{B}_{12}}$ may cause vitamin ${{B}_{12}}$ deficiency anemia.
If the level of vitamin ${{B}_{12}}$ is slightly lesser, it shows symptoms like fatigue, depression, poor memory, headache, pale skin etc.
Good sources of vitamin ${{B}_{12}}$ are meat, milk, fish, cheese etc.

So the correct answer for the question is option (C) Cyanocobalamin.

Note: There are many types of vitamin B and the other given here is,
Thiamin – which is the chemical name for vitamin ${{B}_{1}}$ and it is very much necessary for maintaining a nervous system in good health.
Riboflavin-the chemical name of vitamin ${{B}_{2}}$, which keeps the eyes and skin healthy.
Pyridoxine- is the chemical name of vitamin ${{B}_{6}}$, it helps the body to store the energy obtained from proteins and carbohydrates we have in our diet.
