Question

Which of the following B-group vitamins can be stored in our body?
a.) Vitamin \[{{B}_{1}}\]
b.) Vitamin \[{{B}_{2}}\]
c.) Vitamin \[{{B}_{6}}\]
d.) Vitamin \[{{B}_{12}}\]

Answer 1

Hint: There are eight B vitamins, collectively all 8 vitamins are called B complex vitamins and are as follows.
Thiamine (\[{{B}_{1}}\]), Riboflavin (\[{{B}_{2}}\]), Niacin (\[{{B}_{3}}\]), Pantothenic acid (\[{{B}_{5}}\]), Pyridoxine (\[{{B}_{6}}\]), Biotin (\[{{B}_{7}}\]), Folic acid (\[{{B}_{9}}\]) and Cobalamin (\[{{B}_{12}}\]).
Out of all of these only two can be stored in our body.

Complete step by step answer:
Most of the B-vitamins cannot be stored by the human body and should be consumed every day in the diet.
Over cooking, processing of food and consumption of excess alcohol can destroy the accessibility of many of these B-vitamins.
The human body has a minimum capacity to store the most of the B-group vitamins excluding Cobalmine (\[{{B}_{12}}\])​and folic acid (\[{{B}_{9}}\]), which are going to be stored in the liver.
The vitamin which is going to be stored in the human body is cobalamin (\[{{B}_{12}}\])​.
So, the correct answer is “Option D”.

Additional Information:
Vitamin \[{{B}_{12}}\] is soluble in water like all other groups of B-vitamins.
Cobalamin found naturally in animal products, and available as a supplement via oral or through injection.
Cobalamin has many roles in our body and it supports the function of nerve cells and is required for red blood cell development and in the synthesis of DNA.

Note: The central metal which is present in the cobalamin is cobalt. Cobalamin contain corrin rings in its structure. The corrin ring contains four pyrrole subunits. Cobalamin is the only vitamin containing metal in its structure.
