Macromolecules that primarily serve to store energy include:
-
Carbohydrates: These macromolecules, such as starch and glycogen, act as a primary energy storage form in plants and animals, respectively. Carbohydrates consist of sugar molecules (monosaccharides) that can be linked together to form larger structures.
-
Lipids: Fats and oils are a major form of energy storage in living organisms. Lipids, particularly triglycerides, are composed of glycerol and fatty acids. They provide more energy per gram compared to carbohydrates, making them an efficient way to store energy.
-
Proteins: While proteins are primarily used for structural and functional roles in the body, they can also serve as an energy source when other macromolecules are not available. They are made up of amino acids, and in extreme situations, the body can break down proteins for energy.
Overall, carbohydrates and lipids are the main macromolecules dedicated to energy storage in biological systems.
