Multiple Choice

Which of the following statements about omega-6 fatty acids is TRUE?

They are saturated fatty acids commonly found in animal fats.

They are synthesized in the human body and are not required in the diet.

Linolenic acid is the primary dietary omega-6 fatty acid.

They have their first double bond at the sixth carbon from the methyl (omega) end.

Verified step by step guidance

Step 1: Understand the structure of omega-6 fatty acids. Omega-6 fatty acids are unsaturated fatty acids characterized by having their first double bond at the sixth carbon from the methyl (omega) end of the fatty acid chain. This structural feature distinguishes them from other types of fatty acids, such as omega-3 fatty acids.

Step 2: Clarify the term 'unsaturated fatty acids.' Unsaturated fatty acids contain one or more double bonds in their hydrocarbon chain, unlike saturated fatty acids, which have no double bonds and are fully saturated with hydrogen atoms.

Step 3: Evaluate the incorrect statements. The first option is incorrect because omega-6 fatty acids are unsaturated, not saturated, and are commonly found in plant oils rather than animal fats. The second option is incorrect because omega-6 fatty acids are essential fatty acids, meaning they cannot be synthesized by the human body and must be obtained through the diet. The third option is incorrect because linoleic acid, not linolenic acid, is the primary dietary omega-6 fatty acid.

Step 4: Confirm the correct statement. The correct statement is that omega-6 fatty acids have their first double bond at the sixth carbon from the methyl (omega) end. This is a defining characteristic of omega-6 fatty acids and aligns with their nomenclature.

Step 5: Summarize the importance of omega-6 fatty acids. Omega-6 fatty acids are essential for human health, playing roles in cell membrane structure, inflammatory responses, and other physiological processes. They must be obtained through dietary sources such as vegetable oils, nuts, and seeds.
