Fatty acid - Wikipedia

For example, α-Linolenic acid is classified as a n−3 or omega-3 fatty acid, and so it is likely to share a biosynthetic pathway with other compounds of this type. The ω− x , omega- x , or "omega" notation is common in popular nutritional literature, but IUPAC has depreed it in favor of n − x notation in technical documents. [15]
