Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of proteins and protein-like compounds.
Step 2: Detailed Explanation:
Phytin is not a true protein.
It is a salt of phytic acid (inositol hexaphosphate).
It is a storage form of phosphorus in seeds.
Glutein (A): A true protein (storage protein in wheat).
Calmodulin (C): A true protein (calcium-binding protein).
Zein (D): A true protein (storage protein in maize).
Thus, phytin is not a true protein.
Step 3: Final Answer:
Thus, phytin is not a true protein, which corresponds to option (B).
