Linoleic acid, an omega-6 fatty acid, is converted by the body into

Question

BlackTom AI · Accepted Answer

The question asks about the metabolic fate of linoleic acid, an omega-6 fatty acid, in the body. 
Option 1: palmitic acid. This is a saturated fatty acid that can be produced from fatty acid synthesis pathways, but linoleic acid is not converted into palmitic acid as a primary biological route; thus this option is incorrect for the stated context.
Option 2: alpha-linolenic acid. This is an omega-3 fatty acid, and while there is a shared pathway for desaturation and elongation among fatty acids, linoleic acid is not converted into alpha-linolenic acid in a direct, biologically standard route. Therefore this choice misrepresents the typical metabolic fate of linoleic acid.
Option 3: oleic acid. Oleic acid is an omega-9 monounsaturated fatty acid formed by the desaturation of stearic acid rather than a direct product of linoleic acid metabolism. Linoleic acid does not routinely convert to oleic acid in common physiology, so this option is not correct for linoleic acid's downstream product.
Option 4: arachidonic acid. Indeed, linoleic acid (18:2, n-6) is desaturated and elongated through a series of steps to form dihomo-gamma-linolenic acid (DGLA) and ultimately arachidonic acid (20:4, n-6). This pathway is the canonical route by which dietary omega-6 linoleic acid contributes to signaling molecules and inflammatory mediators. Therefore, this option is correct.
In summary, understanding the omega-6 pathway shows linoleic acid is the precursor that ultimately yields arachidonic acid, while the other listed fatty acids do not represent the direct downstream product of linoleic acid metabolism.
