What is an Omega-6 fatty acid?
Omega-6 fatty acids are also polyunsaturated fatty [PUFA] acids. They are essential fatty acids, so you need to obtain them from your diet. Omega-6 is primarily used for energy, and the most common and abundant member of this family is linoleic acid (LA) (Wikipedia). They have numerous important roles in the body, and contribute to the structure and function of cell membranes. They also play a part in the regulation of gene activity inside the cell. Other members of the family include gamma-linolenic acid (GLA) (Wikipedia) and arachidonic acid (ARA) or (AA) (Wikipedia). Linoleic acid is also considered an essential fatty acid since it cannot be synthesized by the body. However, other members of the omega-6 family can be made from linoleic acid.
