Definition of omega-3
Omega-3s are a group of essential fatty acids, this means that man has to resort to food supplies of this nutrient because it can not synthesize itself.

Chemical definition of omega-3 (complex part for specialist)
The molecules are omega-3 long chain hydrogénocarbonée with several double bonds (also known as polyunsaturated fatty acids: which means that the channel is not fully saturated with hydrogen atom H).
The concept of omega-3 is a generic term that includes various fatty acids: eicosapentaenoic acid (EPA) with 20 C and 5 double bonds, docosahexaenoic acid (DHA) with 22 C and 6 double bonds and acid docosapentaénoique (DPA) with 22 C and 5 double bonds.
As can be seen on 3 of the term omega-3 means the strict sense, 3 unsaturated, fatty acids or some part of this family have more than 3 links (5 ,…), it is therefore rather a group of fatty acids in the broad sense.
