Total fatty acid composition of duck fatty tissues

Total lipids extracted from duck fatty tissues were fractionated on thin layer plates into polar lipids and neutral lipids. Neutral lipids were similarly fractionated into their components. Fatty acid methyl esters from total lipids were fractionated by gas-liquid-chromatography. Results indicated that duck fatty tissues are mostly formed by neutral lipids and that triglycerides comprise the vast majority of neutral lipids. Results also indicated that the major fatty acids in duck lipids are: oleic greater than linoleic greater than stearic greater than palmitoleic. About 73% of all fatty acids present belong to the C-18 series. The unsaturation level for duck lipids is about 73%.
