Answer
Formation of amino acids
Explanation
Hydrolysis of a protein involves breaking the peptide bonds between amino acids, resulting in the formation of individual amino acids.
Common mistake
Peptide Bond Drawing Error
Students often incorrectly draw the peptide bond by not showing the correct connection between the amine and carboxylic acid groups.
To correctly draw a peptide bond, remember that it forms between the carbon of the carboxylic acid group and the nitrogen of the amine group. The formula for the peptide bond is R1CO-NHR2, where R1 and R2 are the side chains of the amino acids. Ensure to illustrate the loss of a water molecule (H2O) during the condensation reaction.
