When
the body cannot synthetize a fatty acid, it is called "Essential".
The body cannot fonction without it.
The
Essential Fatty Acid or EFA must be provided by the food, but it
is also important to apply them on the skin.
These
two acids are linoleic acid and alpha linolenic acid :
Linoleic
acid C18:2 6
Linoleic acid is an omega-6 fatty acid.
It is biologically inactive before it is catalysed by our body into
others omega-6 fatty acids : gamma linoleic acid (GLA), dihomo-gamma
linoleic acid (DHGLA) and arachidonic acid (AA).
Alpha
linolenic acid C18:3 3
It is an omega-3 fatty acid.
Other omega-3 fatty acids are manufactured in the body using alpha-linolenic
acid for example the eicosapentaenoic acid (EPA) and docosahexaenoic
acid (DHA).
