lipid glucose amino acid hydrocarbon
I gave my students this multiple choice question: Peptide bonds in proteins can be broken down by the enzyme peptidase. Adrian orders a hamburger and French fries for lunch. He adds cheese and mayonnaise to his hamburger, and then sits down to eat lunch with his friends. Which structure would most likely result from the action of peptidase in Adrian's small intestine?

Only one answer is correct among these 4 choices:
- lipid
- glucose
- amino acid
- hydrocarbon

Could you tell me which one is correct?

amino acid
