Verified step by step guidance

Understand the role of biomolecules in energy storage: Different biomolecules serve distinct functions in the body. Carbohydrates are primarily used for short-term energy, while lipids are specialized for long-term energy storage.

Review the structure and properties of lipids: Lipids, such as triglycerides, are composed of glycerol and fatty acids. Their hydrophobic nature allows them to be stored efficiently in adipose tissue without attracting water, making them ideal for long-term energy storage.

Compare lipids to carbohydrates: Carbohydrates, like glycogen, are stored in limited quantities and are quickly metabolized for immediate energy needs. Lipids, on the other hand, provide more energy per gram due to their higher proportion of carbon-hydrogen bonds, which release energy during oxidation.

Consider the storage mechanism in animals: Animals store lipids in adipose tissue, which serves as an energy reserve during periods of fasting or increased energy demand. Proteins and nucleic acids are not primarily used for energy storage; proteins are involved in structural and functional roles, while nucleic acids store genetic information.

Conclude that lipids are the primary biomolecule for long-term energy storage in animals, as their structure and storage properties are optimized for this function.
