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: -Lipids, including triglycerides, fat cells, lipoproteins, and cell membranes, are processed in various forms in the body. Any excess energy absorbed is converted into triglycerides, which along with globules make up 90 percent of fat cells. To keep the body going, these fat cells have enough energy storage for 30 days.

Detailed explanation-3: -Unlike the carbohydrates, the body is able to store lipids in the body, and they are therefore an important long term source of energy.
