What food has the most energy per gram?
Fats have the greatest amount of food energy per mass, up to 9 kcal g − 1 . Most of the carbohydrates and proteins have approximately 4 kcal g − 1 , whereas fibers have less due to its low digestibility and absorbance in human bodies (Insel et al., 2012).
Which biomolecules has the most energy?
There are four classes of biological molecules: fats , carbohydrates, proteins, and nucleic acids. Of these, fats produce the most energy per gram at a whopping nine calories per gram.
Do vitamins yield energy?
Unlike the macronutrients, vitamins do not serve as an energy source for the body or provide raw materials for tissue building. Rather, they assist in energy-yielding reactions and facilitate metabolic and physiologic processes throughout the body.
