The H-bonds formed in the tertiary structure of proteins can be differentiated from those formed in secondary structures. What is the major distinguishing factor?
A) The H-bonds in 3° structures are significantly stronger than those found in 2° structures.
B) The H-bonds in 3° structures are more random than those formed in 2° structures.
C) The H-bonds in 3° structures are formed by predictable interactions among the peptide backbone α-amine and α-carboxylate groups.
D) The H-bonds in 3∘ structures are formed by interactions involving the side chain R-groups.
E) Both B and D are correct.
Tertiary Structure
The three-dimensional shape of a protein molecule determined by interactions among its amino acids' side chains, beyond simple folding.
H-Bonds
Hydrogen bonds, a type of weak chemical bond that occurs when a hydrogen atom covalently bonded to one electronegative atom is also attracted to another electronegative atom.
Peptide Backbone
The main structural component of a peptide, consisting of a repeated sequence of amino acids linked by peptide bonds.
- Comprehend the importance of hydrogen bonding in determining the structure and stability of proteins.
- Distinguish between different types of bonding and interactions (e.g., hydrogen bonds) at various structural levels of proteins.
