Question:
Which structure of protein represents its constitution?
Which structure of protein represents its constitution?
Show Hint
Primary structure = amino acid sequence.
Updated On: Jun 18, 2026
- Primary structure
- Secondary structure
- Tertiary structure
- Quaternary structure
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
The constitution of a protein is determined by the sequence of amino acids linked together.
Step 1: Define primary structure.
Primary structure represents the exact order of amino acids in a polypeptide chain.
Step 2: Compare with other structures.
Secondary structure: \[ \alpha\text{-helix},\ \beta\text{-sheet} \] Tertiary structure: Three-dimensional folding. Quaternary structure: Association of multiple chains. Hence, \[ \boxed{\text{Primary structure}} \] represents the constitution of protein.
