Omega-3 fatty acids are a type of polyunsaturated fat (like omega-6), considered an essential fatty acid because it cannot be manufactured by the body. As a result, people must obtain omega-3 fatty acids from foods such as fish, nut, and plant-based oils such as canola oil and sunflower oils.hat are they? Omega-6 fatty acid is also a polyunsaturated fat, essential for human health because it cannot be made in the body. For this reason, people must obtain omega-6 fatty acids by consuming foods such as meat, poultry, and eggs as well as nut and plant-based oils such as canola and sunflower oils.
Fats and Oils. Sometimes it is important to distinguish between fats and oils, or more completely, animal fats and vegetable oils. The distinction between these rests on what kinds of fatty acids went into the formation of that fat. Here (and also in Example 7 in your workbook) we have the structural formulas for four such fatty acids -- stearic acid, oleic acid, linoleic acid and linolenic acid. Note that all four have 18 carbon atoms.
