Answer:
The correct answer is b. likely to be found in beta turns.
Explanation:
Proline is the amino acid which is unique from other amino acids as the side chain of proline is connected which gives it a cyclic structure. Beta turns are the secondary structure found in proteins that helps in the changing of direction of polypeptide chain in the protein.
The amino -acid proline is commonly found in beta turns because the unique cyclic structure of proline suits the beta-turn organization. Glycine is another amino acid that is abundant in beta turn because of its small size.
Therefore the correct answer is b. likely to be found in beta turns.
