Abstract

 Ag+- and RP-HPLC have been used to study the triacylglycerol fraction of a dietary supplement containing fish oil. The fatty acid (FA) distribution in the glycerol backbone of the triacylglycerol fraction was determined by stereospecific analysis. Eicosapentaenoic acid, the most abundant poly unsaturated FA, was predominantly located in the sn-3 position, while docosahexaenoic and docosapentaenoic acids were generally located in the sn-2 position. The nutritional significance of these findings is briefly discussed.
