Concept explainers
(a)
Interpretation:
The vitamins that are associated with the fat-soluble vitamins are to be stated.
Concept introduction:
Vitamins are the organic compounds that are essential in small amounts for the proper functioning of the human body. The vitamins should be included in the diet. Vitamins are the micronutrients that are essential for the proper functioning of the human body. They are classified into two types; one is water soluble and the other is fat soluble.
(b)
Interpretation:
The vitamin that is associated with the term thiamin is to be stated
