Answer:
Protein may contain amino acids but lipids do not.
Explanation:
First of all, Lipids aren't polymers because they are not built by monomers. Of course lipids contain carbon, so do all the other macromolecules such as carbs, proteins, and nucleic acids. Lipids contain carbon too. So last not but not least, protein's contain amino acids, which is something lipids certainly do not contain. I'm not a science expert but I hope this helped. Good luck!
