What type of fatty acids are linoleic and linolenic acids?
Likewise, what type of fatty acid is linolenic acid?
Alpha-linolenic acid (ALA) is a polyunsaturated fatty acid (PUFA). It is a member of the group of essential fatty acids called omega-3 fatty acids. Alpha-linolenic acid, in particular, is not synthesized by mammals and therefore is an essential dietary requirement for all mammals.
One may also ask, what is the difference between linoleic acid and linolenic acid? Linolenic acid most commonly refers to alpha-linolenic acid (ALA), an omega-3 fatty acid found in many nuts, vegetables and oils. Linoleic acid, on the other hand, typically refers to a type of omega-6 fatty acid commonly found in nut, seed and refined vegetable oils.
Consequently, why are linoleic and linolenic acids essential fatty acids?
All fats, including saturated fatty acids, have important roles in the body. However, the most important fats are those that the body cannot make and thus must come from the food we eat. These essential fatty acids (EFAs) are based on linoleic acid (omega-6 group) and alpha-linolenic acid (omega-3 group).
What do linoleic acid and linolenic acid have in common?
Linoleic acid is the other essential fatty acid, but it, and the other n−6 fatty acids, compete with n−3s for positions in cell membranes and have very different effects on human health. Multiple studies have shown a relationship between α-linolenic acid and an increased risk of prostate cancer.
