Question:
Which of the following is a correct combination of components for activation of lactoperoxidase system in milk?
Which of the following is a correct combination of components for activation of lactoperoxidase system in milk?
Show Hint
Lactoperoxidase system:
Lactoperoxidase + Thiocyanate + H\(_2\)O\(_2\).
Produces antimicrobial hypothiocyanite.
Lactoperoxidase + Thiocyanate + H\(_2\)O\(_2\).
Produces antimicrobial hypothiocyanite.
Updated On: Aug 18, 2026
- Lactoferrin-Thiocyanate-Hydrogen peroxide
- Lactoperoxidase-Thiocyanate-Hydrogen peroxide
- Lactoperoxidase-Thiobarbiturate-Hydrogen peroxide
- Lactoperoxidase-Thiocyanate-Hydrogen oxide
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
The lactoperoxidase system is a natural antimicrobial system in milk.
It requires specific components for activation.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the components of the lactoperoxidase system.
Step 3: Detailed Explanation:
The lactoperoxidase system requires three components:
- Lactoperoxidase (enzyme)
- Thiocyanate (SCN\(^-\))
- Hydrogen peroxide (H\(_2\)O\(_2\))
These components produce hypothiocyanite, which has antimicrobial activity.
Lactoferrin is a separate antimicrobial protein.
Thiobarbiturate is not a component.
Hydrogen oxide is not a correct term.
Thus, the correct combination is lactoperoxidase-thiocyanate-hydrogen peroxide.
Step 4: Final Answer:
The correct combination is Lactoperoxidase-Thiocyanate-Hydrogen peroxide.
Hence, the correct option is (B). \bigskip
