ABSTRACT

The Omega-3, 6 and 9 fatty acids are important for promoting heart health, brain development and immune system function. In this investigation, the muscle tissue of Ophionereis dubia from Qeshm region of Persian Gulf in April 2015 were separately extracted for their lipid content especially Omega-3, 6 and 9 fatty acids Composition using the Blight & Dyer method. The components detected were saturated fatty acid Palmitic acid (20%) and stearic acid (14%), monounsaturated fatty acid Oleic acid (23%), polyunsaturated fatty acids Arachidonic acid (4.5%), Docosahexaenoic acid (5.5%) and Eicosapentaenoic acid (10.5%), and one ester including Palmitic acid–methylester (9.5%).
