Question 11
When two amino acids react in a condensation reaction, water is eliminated and a peptide link is formed. Which of the following represents this process? A B C D
Worked Solution & Example Answer:When two amino acids react in a condensation reaction, water is eliminated and a peptide link is formed - Scottish Highers Chemistry - Question 11 - 2023
Step 1
Step 2
Analyze the options
Answer
We need to look at the structures presented in options A, B, C, and D to identify which one represents the formation of a peptide bond. In a peptide bond formation, the amine group (–NH2) of one amino acid reacts with the carboxyl group (–COOH) of another amino acid.
Step 3
Determine the correct option
Answer
Upon reviewing the options:
- Option A: does not show correct bonding.
- Option B: indicates a different reaction pathway.
- Option C: correctly illustrates the condensation of two amino acids, showing the elimination of water.
- Option D: also does not illustrate a peptide bond correctly.
Therefore, option C is the correct representation of the described process.
