Detailed explanation-1: -Fats (lipids) Fats are the primary long-term energy storage molecules of the body.
Detailed explanation-2: -Lipids are an efficient source of energy (9kcal per gram) that the body stores in relative abundance. They also play an important role as building blocks for cell membranes, hormones, and physiologically active substances.
Detailed explanation-3: -They are surrounded by water, which sets a lower limit to the amount of space required to store them and the weight they add. Because of these differences, lipids are used in long-term energy storage (adipose, or fat, tissue), and carbohydrates are used in short-term energy storage (glycogen).
Detailed explanation-4: -Lipids are considered to be a very crucial source of energy. It is considered to be a better source than carbohydrates because it yields more fatty acids. Also, lipids are compact in structure so they can store energy quite efficiently.
