Sphingolipids and glycerophospholipids from natural sources contain a heterogeneous mixture of fatty acids attached to the sphingosine or glycerol moiety, respectively. 

We have compiled the typical fatty acid composition of Cayman natural lipids here (PDF). Please note the actual composition may vary according to dietary history and growth condition of the source. The exact identity may vary from batch to batch. For additional information, please contact our Technical Support scientists.
