HUMAN NUTRITION

Detailed explanation-1: -As discussed previously, glucose is stored in the body as glycogen. While glycogen provides a ready source of energy, lipids primarily function as an energy reserve. Glycogen is quite bulky with heavy water content, thus the body cannot store too much for long.

Detailed explanation-2: -The main biological functions of lipids include storing energy, as lipids may be broken down to yield large amounts of energy. Lipids also form the structural components of cell membranes, and form various messengers and signaling molecules within the body.

Detailed explanation-3: -Lipids are the highest long-term energy storage molecules. One gram of lipids yields 9 kcal of energy.
