Question:
If side chains of amino acids interact with each other, which of the following would be termed as a salt bridge?
If side chains of amino acids interact with each other, which of the following would be termed as a salt bridge?
Show Hint
Salt bridges are formed between positively charged (basic) and negatively charged (acidic) amino acids and are crucial for protein stability.

- Tyr - Phe
- Cys - Cys
- Lys - Glu
- Ala - Val
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
A salt bridge is a type of non-covalent interaction between oppositely charged side chains, typically between a basic amino acid (like Lysine) and an acidic amino acid (like Glutamate). In this case, the Lys - Glu pair forms a salt bridge.
