Here's why:
* Macromolecules: These are large complex molecules made up of smaller repeating subunits. Examples include carbohydrates, lipids, proteins, and nucleic acids.
* Biomolecules: This is a broader term encompassing any molecule found in living organisms, including macromolecules and smaller molecules like water, vitamins, and minerals.
So, while lipids are biomolecules, they are specifically classified as macromolecules due to their large size and complex structure.
