Final answer:
Lipids are not considered polymers because they lack repeating monomers.
Step-by-step explanation:
Lipids are not considered polymers because they lack repeating monomers.
Lipids are a diverse group of compounds that are united by a common feature. They are hydrophobic, or insoluble in water, because they are non-polar molecules that contain non-polar hydrocarbon chains. Unlike polymers, which are made up of repeating units called monomers, lipids do not exhibit this repetitive structure.
