Answer:
chemically reacted (dehydrated)
Step-by-step explanation:
- By definition, polymers are macromolecules formed by the combination or interlinking of a single repeating unit i.e. a monomer.
- Unlike carbohydrates and proteins, lipids do not form polymers. Lipids consist of a unique starting molecule that is different from the other units.
- Lipids are formed by the chemical combination of sub-units through reactions such as dehydration. Fatty acids combine through dehydration and release water.
- This process only allow lipids to elongate in one direction only whereas carbohydrates and proteins can form complex, branched structures.
