CBSE Class 12-science Answered

Dear student,

The B (B1) vitamin thiamine  is essential for the metabolism of carbohydrates into the simple sugar glucose.

Riboflavin (B2) is important in the breakdown of carbohydrates, fats and proteins, and, like thiamine, it acts as a coenzyme in the process. It is also significant in the maintenance of the skin and mucous membranes, the cornea of the eye and for nerve sheaths.

Niacin (B3)is needed for the metabolism of food, the maintenance of healthy skin, nerves and the gastrointestinal tract.

Pyridoxine (B6)is needed (like some of the other B vitamins) for the breakdown of carbohydrates, proteins and fats. Pyridoxine is also used in the production of red blood cells, as well as in the biochemical reactions involved in the metabolism of amino acids (the building blocks of protein).

Hope this helps.
