Final answer:
The primary function of linoleic acid and alpha-linolenic acid in the body is to provide structural support and insulation. They are essential fatty acids that the body cannot synthesize and must be obtained from the diet.
Step-by-step explanation:
The primary function of linoleic acid and alpha-linolenic acid in the body is to provide structural support and insulation. They are essential fatty acids that the body cannot synthesize and must be obtained from the diet. These fatty acids are needed for normal growth and development, and their deficiency can lead to various health issues.
Linoleic acid is used by the body to synthesize other unsaturated fatty acids and is important for the transport and metabolism of cholesterol. Alpha-linolenic acid is a precursor for the synthesis of long-chain unsaturated fatty acids, such as eicosapentaenoic acid and docosahexaenoic acid, which are important for brain function and reducing inflammation.
