Updated On: May 19, 2026
- Pyruvic acid
- Lactic acid
- Folic acid
- Arachidonic acid
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Prostaglandins are lipid compounds with hormone-like effects derived from fatty acids.
Step 2: Meaning
A precursor is the starting material from which a more complex molecule is synthesized.
Step 3: Analysis
Arachidonic acid is a 20-carbon polyunsaturated fatty acid. It is released from cell membrane phospholipids and converted by cyclooxygenase (COX) enzymes into prostaglandins.
Step 4: Conclusion
Arachidonic acid is the essential metabolic precursor for the biosynthesis of prostaglandins.
