Worked Solution & Example Answer:In a protein, hydrogen bonding takes place during the formation of the A - VCE - SSCE Chemistry - Question 7 - 2022 - Paper 1
Step 1
B. primary, secondary and tertiary structures only.
Answer
Hydrogen bonding is a critical interaction in protein structure. It primarily plays a role during the formation of the secondary, tertiary, and quaternary structures of proteins.
-
Primary Structure: The primary structure refers to the linear sequence of amino acids in a protein. Hydrogen bonds do not form in this stage as the sequence is simply a chain of amino acids.
-
Secondary Structure: Hydrogen bonds form between the backbone atoms in a polypeptide chain, leading to structures such as alpha-helices and beta-pleated sheets.
-
Tertiary Structure: Interaction between side chains (including hydrogen bonds) contributes significantly to the overall 3D shape of the protein.
-
Quaternary Structure: Although hydrogen bonds can also be significant in stabilizing quaternary structures, the question primarily emphasizes the earlier stages where they are most crucial.
Therefore, the correct answer is option B: primary, secondary and tertiary structures only.
