Explanation:

Vitamins are organic compounds that are essential in small amounts for various metabolic and biosynthetic reactions in the body, often acting as coenzymes. Inorganic nutrients like minerals are different from vitamins. Vitamins are not the main source of energy (carbohydrates, fats are for energy - providing), and they are not inorganic ions for functions like skeletal formation etc.

Answer:

essential nutrients that serve as coenzymes for many metabolic and biosynthetic reactions
