Sidebar: Some quick fatty acids facts

-    Fatty acids range in length from two to 22 carbon chains. Some fatty acids are saturated, which means that they lack double bonds in their carbon chain, while others are unsaturated, meaning that they have anywhere from one to six double bonds in their carbon chain. The final carbon atom at one particular end of the carbon chain is called the "omega" carbon.

-    Polyunsaturated fatty acids have more than one double bond and are classified according to the location and number of double bonds in their chemical structure. Omega-3 fatty acids have their first double bond at the third carbon atom, while omega-6 fatty acids have theirs at the sixth carbon atom in the chain. The omega-3 fatty acids are linolenic, eicosapentaenoic (EPA), and docosahexaenoic (DHA).
