Question: What type of interaction stabilizes the secondary structure of peptides?

Options:

Correct Answer: Hydrogen bonds

Solution:

Hydrogen bonds between the backbone amide and carbonyl groups stabilize the secondary structure, such as alpha helices and beta sheets.

What type of interaction stabilizes the secondary structure of peptides?

What type of interaction stabilizes the secondary structure of peptides?

Step 1: Understand that peptides are chains of amino acids.
Step 2: Learn that the secondary structure refers to specific shapes that these chains can form, like alpha helices and beta sheets.
Step 3: Identify that the backbone of the peptide has specific groups called amide and carbonyl groups.
Step 4: Recognize that hydrogen bonds are weak attractions that can form between these amide and carbonyl groups.
Step 5: Conclude that these hydrogen bonds help hold the secondary structures (like alpha helices and beta sheets) together, making them stable.
