Compare and contrast the functions of carbohydrates to the function of proteins

While protein's primary role is structural, carbohydrates primarily serve as an energy source. In fact, glucose -- one of the simplest carbohydrates -- is your body's preferred energy currency. Whenever your body derives energy from protein because of a low supply in carbs, protein components must undergo a number of biochemical changes to be useful in energy production. Proteins serve above all as your body's building blocks. Every cell needs them for structure, but they also play important roles as molecule transporters, hormones, disease-fighting agents and enzymes Some carbs -- namely fiber -- are important for bowel health and waste elimination.

Functions of carbohydrates and proteins:

Carbohydrates and proteins are the major biological macro molecules that help in building up our body, both are used for gaining energy whereas the major function of the proteins is to build up hair and nails, maintaining the body metabolism through hormones etc.

Carbohydrates on the other hand are sweeteners that majorly yield glucose on hydrolysis. Structurally also proteins are made up of amino acids and carbohydrates are made up of polysaccharides

The above mentions are the difference and comparison between carbohydrates and proteins.
