A carb is a natural particle comprising of carbon (C), oxygen (O) and hydrogen (H) atoms, as a rule with a hydrogen–oxygen molecule proportion of 2:1; at the end of the day, with the exact equation Cm(H2O)n (where m could be not quite the same as n). This formula remains constant for monosaccharaides.


Calorie is used to measure the energy. In nourishment and regular dialect, calories allude to energy utilization through drinking and eating, and usage of energy through physical action.

Carbs are defined in three major groups that include simple starchy carbohydrates, complex starchy carbohydrates and complex fibrous carbohydrates.

Calories are just a measurement so it is used to measure the fats, carbohydrates and proteins in different food. So it has no type.

  • Function:

From the above article we can conclude that all these elements are important for body’s development. Protein and carbs are the macromolecules whereas calories are the unit used for the measurement of energy.
