Question

Which of the following interactions is LEAST likely to play a significant role in the stabilization of a protein's tertiary structure?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
 **Primary Concept**: Protein tertiary structure stabilization
 **Related Topics**: Non-covalent interactions, covalent interactions, protein folding
 **Prerequisites**: Understanding of different types of chemical bonds and their properties.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the interaction LEAST likely to stabilize a protein's tertiary structure.
**Method & Steps**:
 1. Analyze each interaction's role in protein folding.
  Reasoning: Tertiary structure refers to the 3D arrangement of a polypeptide chain. Several interactions contribute to its stability.
 2. Identify the interaction that is not typically involved in protein structure.
  Working:  
        * Hydrophobic interactions: Nonpolar amino acid side chains cluster in the protein's core, away from water, stabilizing the structure.
        * Hydrogen bonds: Form between polar amino acid side chains and the peptide backbone, contributing to stability.
        * Disulfide bonds: Covalent bonds between cysteine residues, creating strong cross-links.
        * Ester bonds: These are typically found in lipids and not in the peptide backbone or side chains of proteins.
 3. Determine the least significant interaction.
  Result: Ester bonds are not involved in protein tertiary structure stabilization.
  Verification: The other options are all crucial for protein folding and stability.
 ## OPTION ANALYSIS
A :x: Hydrophobic interactions are crucial for protein folding.
B :x: Hydrogen bonds are essential for stabilizing the protein's structure.
C :x: Disulfide bonds provide strong covalent links within the protein.
D ✓: Ester bonds are not involved in the stabilization of protein tertiary structure.
 ## LEARNING AIDS
 **Common Mistakes**: Confusing ester bonds with peptide bonds or disulfide bonds.
  **How to avoid**: Focus on the chemical nature of each bond and its location within a protein.
 **Quick Tips**: Remember that ester bonds are primarily found in lipids and not proteins.  Focus on the interactions that occur between amino acid side chains and the polypeptide backbone.
