Proteins provide four kilocalories of energy per gram; however providing energy is not protein’s most important function. They also provide structure to bones, muscles and skin, and play a role in conducting most of the chemical reactions that take place in the body. Scientists estimate that greater than one-hundred thousand different proteins exist within the human body.
