The complete hydrolysis of a protein produces
Correct answer: C. a mixture of amino acids
- A. glucose molecules
- B. fatty acids and glycerol
- C. a mixture of amino acids
- D. urea and ammonia
Explanation
Every peptide bond is broken by boiling with concentrated acid or by protease enzymes, releasing the constituent amino acids, which can then be separated by chromatography or electrophoresis. Glucose comes from the hydrolysis of carbohydrates and fatty acids with glycerol from fats. Urea is a later metabolic product formed when surplus amino acids are deaminated in the liver.

About Importance of Proteins
Proteins are polymers of amino acids joined by peptide bonds, and their biological roles depend on primary, secondary, tertiary and quaternary structure. Coverage includes enzymes, hormones, antibodies, transport proteins, muscle fibres and structural tissues, together with denaturation and the effects of heat, pH and chemicals.
