What is gamma linolenic acid (GLA) derived from?

Alpha linolenic acid
Linoleic acid
Stearic acid
Oleic acid

The correct answer is: Linoleic acid

Gamma linolenic acid (GLA) is an omega-6 fatty acid that is derived from linoleic acid. Linoleic acid is a polyunsaturated fatty acid that serves as a precursor for the formation of GLA in the body. Upon the action of specific enzymes, linoleic acid can undergo enzymatic conversion to form GLA, making it the direct source for this beneficial fatty acid. Options stemming from other fatty acids such as alpha linolenic acid, stearic acid, and oleic acid do not provide the necessary building blocks for GLA synthesis. Alpha linolenic acid is an omega-3 fatty acid, while stearic and oleic acids are saturated and monounsaturated fats, respectively. Therefore, they do not contribute directly to the production of GLA.
