Hydrolysis of proteins yields:

• A. Nucleotides
• B. Simple sugars
• C. Amino acids
• D. Fatty acids

Answer: (C)

Proteins are polymers made from amino acids linked by peptide bonds. Hydrolysis uses water to break those bonds, so a protein is split into its monomer units. When fully hydrolyzed, proteins yield amino acids (the building blocks of proteins), though you might also get shorter peptides along the way. The other options aren’t produced by hydrolyzing proteins: nucleotides come from nucleic acids, simple sugars from carbohydrates, and fatty acids from fats.
