Which of the following is NOT a ketone body?
Show Hint
Ketone bodies:
- Acetone, Acetoacetate, \(\beta\)-hydroxybutyrate.
- Produced during fasting, diabetes, and low-carbohydrate diets.
- Acetone, Acetoacetate, \(\beta\)-hydroxybutyrate.
- Produced during fasting, diabetes, and low-carbohydrate diets.
Updated On: Sep 1, 2026
- Acetone
- Acetoacetate
- \(\beta\)-hydroxybutyrate
- Isobutyryl CoA
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of ketone bodies and metabolism.
Step 2: Detailed Explanation:
The three ketone bodies are:
1. Acetone
2. Acetoacetate
3. \(\beta\)-hydroxybutyrate
They are produced during ketogenesis when acetyl-CoA accumulates.
Isobutyryl CoA (D) is an intermediate in amino acid metabolism (valine degradation).
It is not a ketone body.
Thus, isobutyryl CoA is not a ketone body.
Step 3: Final Answer:
Thus, isobutyryl CoA is NOT a ketone body, which corresponds to option (D).

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
In light of the above statements, choose the correct answer from the options given below. - The serum level of which of the following metabolites can effectively distinguish "Vitamin B12 deficiency" from "Folate deficiency" ?
