WebbThe Functions of Fats in the Body Storing Energy The excess energy from the food we eat is incorporated into adipose tissue, or fatty tissue. Most of the energy required by the human body is provided by carbohydrates and lipids. As discussed in the Carbohydrates unit, glucose is stored in the body as glycogen. WebbCells must be able to exclude, take in, and excrete various substances, all in specific amounts. In addition, they must able to communicate with other cells, identifying themselves and sharing information. To perform these roles, the plasma membrane needs lipids, which make a semi-permeable barrier between the cell and its environment.
