Question

Which among the following are \(\omega\)-6 polyunsaturated essential fatty acids?

• A. 18:2 Linoleic acid
• B. 18:3 \(\alpha\)-Linolenic acid
• C. 18:3 \(\gamma\)-Linolenic acid
• D. 20:4 Arachidonic acid

Hint:

(\omega\)-6 fatty acids, such as linoleic acid and arachidonic acid, are crucial for cellular function and inflammatory responses.

Answer 1

The Correct Option is A, C, D

Step 1: Understanding \(\omega\)-6 fatty acids.
\(\omega\)-6 polyunsaturated fatty acids are essential fats that the body cannot produce and must be obtained through diet. These fats play crucial roles in inflammation, brain function, and cellular structure.
Step 2: Analyzing the options.
- (A) Correct, 18:2 Linoleic acid is a common \(\omega\)-6 fatty acid and is essential for the body.
- (B) Incorrect, 18:3 \(\alpha\)-Linolenic acid is an \(\omega\)-3 fatty acid, not \(\omega\)-6.
- (C) Correct, 18:3 \(\gamma\)-Linolenic acid is an \(\omega\)-6 fatty acid.
- (D) Correct, 20:4 Arachidonic acid is a key \(\omega\)-6 fatty acid involved in the synthesis of eicosanoids, which regulate inflammation.
Step 3: Conclusion.
Thus, the correct answers are (A) 18:2 Linoleic acid, (C) 18:3 \(\gamma\)-Linolenic acid, and (D) 20:4 Arachidonic acid.
