A healthy human converts linoleic acid into which substance?

Linoleic acid is an essential fatty acid belonging to the omega-6 fatty acid family. The body has the ability to convert linoleic acid into gamma-linolenic acid (GLA) through a series of enzymatic reactions. This conversion is significant because GLA has several health benefits, including anti-inflammatory properties and roles in various physiological processes.

Understanding this conversion is essential in dietary contexts, as it highlights the importance of including sources of linoleic acid, which is commonly found in plant oils (such as safflower and sunflower oils), nuts, and seeds, in a balanced diet. The body's ability to convert linoleic acid to GLA also showcases the importance of omega-6 fatty acids in maintaining overall health.

The other options do not accurately reflect the conversion pathway of linoleic acid. Saturated fatty acids and cholesterol do not derive from linoleic acid, nor is docosahexaenoic acid (DHA), an omega-3 fatty acid, synthesized from linoleic acid. Thus, the recognition that linoleic acid can be converted into GLA provides a clear understanding of its metabolic role within the body.
