Question:
Which of the following is a \(\omega\)-9 fatty acid?
Which of the following is a \(\omega\)-9 fatty acid?
Show Hint
\(\omega\)-9:
- First double bond at carbon 9.
- Erucic acid is C22:1 \(\omega\)-9.
- Oleic acid is also a \(\omega\)-9 fatty acid.
- First double bond at carbon 9.
- Erucic acid is C22:1 \(\omega\)-9.
- Oleic acid is also a \(\omega\)-9 fatty acid.
Updated On: Sep 1, 2026
- Erucic acid
- Palmitoleic acid
- Gamma-Linolenic acid
- Eicosapentaenoic acid
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of fatty acid nomenclature.
Step 2: Detailed Explanation:
\(\omega\)-9 fatty acids have the first double bond at the 9th carbon from the methyl end.
Erucic acid: C22:1 \(\omega\)-9 (cis-13-docosenoic acid).
Palmitoleic acid (B): \(\omega\)-7 fatty acid.
Gamma-Linolenic acid (C): \(\omega\)-6 fatty acid.
Eicosapentaenoic acid (D): \(\omega\)-3 fatty acid.
Thus, erucic acid is a \(\omega\)-9 fatty acid.
Step 3: Final Answer:
Thus, erucic acid is a \(\omega\)-9 fatty acid, which corresponds to option (A).

- Which of the following molecules can be classified under glycosphingolipid category?
- The bicarbonate buffer is a principal buffering system in blood plasma. The ratio of the bicarbonate to carbonic acid required to maintain pH of plasma at 7.4 is:
- 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" ?

List-I (Name of the Enzyme) & List-II (Class of the enzyme)
(A). Pyruvate carboxylase & (I). Oxidoreductase
(B). Fumarase & (II). Hydrolase
(C). Phospholipase & (III). Lyase
(D). Nitrogenase & (IV). Ligase
