Fatty Acid Profiles of Livers from Two Marine Fishes Inhabiting Sudanese Red Sea Coast

摘要

Fish livers a good source of long-chain polyunsaturated fatty acids and omega 3, are usually discarded as a waste when fish are processed for human consumption in Sudan. Highly fresh Triaenodon obesus and Hipposcarus harid fish were purchased from Port Sudan fish central market during December 2014. The fatty acid profiles of the livers of these commercially important fish were determined. The polyunsaturated and saturated fatty acids ratio in the livers oil of T. obesus and H. harid was 1:2.2 and 1:1.38, respectively. The Palmatic (16:0), Pentadecenoic (12:0) and Arachidic acids were the highest in both species. The poly chain unsaturated fatty acids Linolenic (18:3n - 3), Eicosapentaenoic (20:5n - 3) and Docosahexaenoic (22:6n - 3) were detected in the liver of both species. The highest values of above poly chain unsaturated fatty acids were detected in T. obesus .
