Fish is the best source of polyunsaturated fatty acids (PUFA), specifically n-3 fatty acids, especially eicosapentaenoic acid and docosahexaenoic acid. The objective of the present study was to determine the fat content and fatty acid compositions of 34 marine water fish species from the Mediterranean Sea. The fatty acid compositions of fish consisted of 30.10-46.88% saturated fatty acids, 11.83-38.17% monounsaturated fatty acids and 20.49-49.31% PUFA. In most species, the following fatty acids were identified: mystiric acid (C14:0, 0.72-8.09%), pentadecanoic acid (15:0, 0.05-2.35%), palmitic acid (C16:0, 15.97-31.04%), palmitoleic acid (C16:1, 1.48-19.61%), heptadecanoic acid (C17:0, 0.31-1.84%), cis-10-heptadecenoic acid (C17:1, 0.17-2.01%), stearic acid (C18:0, 2.79-11.20%), oleic acid (C18:1n9, 2.44-28.97%), linoleic acid (C18:2n-6, 0.06-3.48%), arachidonic acid (C20:4n-6, 0.12-10.72%), cis-5,8,11,14,17-eicosapentaenoic acid (C20:5n-3, 1.94-10%) and cis-4,7,10,13,16,19-docosahexaenoic acid (C22:6n-3, 3.31-31.03%). The proportions of n-3 PUFA ranged from 12.66% for annular seabream to 36.54% for European hake, whereas the proportions of PUFA n-6 were between 1.24% for oceanic puffer and 12.76% for flathead mullet. The results of this study show that these fish species were rich in n-3 PUFA, especially, eicosapentaenoic acid and docosahexaenoic acid.
鱼类是多不饱和脂肪酸（PUFA）的最佳来源，特别是 n-3 脂肪酸，尤其是二十碳五烯酸（EPA）和二十二碳六烯酸（DHA）。本研究的目的是确定来自地中海的 34 种海洋鱼类的脂肪含量和脂肪酸组成。鱼类的脂肪酸组成包括 30.10-46.88%的饱和脂肪酸、11.83-38.17%的单不饱和脂肪酸和 20.49-49.31%的 PUFA。在大多数物种中，鉴定出以下脂肪酸：迷迭香酸（C14:0，0.72-8.09%）、十五烷酸（15:0，0.05-2.35%）、棕榈酸（C16:0，15.97-31.04%）、棕榈油酸（C16:1，1.48-19.61%）、十七烷酸（C17:0，0.31-1.84%）、顺-10-十七碳烯酸（C17:1，0.17-2.01%）、硬脂酸（C18:0，2.79-11.20%）、油酸（C18:1n9，2.44-28.97%）、亚油酸（C18:2n-6，0.06-3.48%）、花生四烯酸（C20:4n-6，0.12-10.72%）、顺-5,8,11,14,17-二十碳五烯酸（C20:5n-3，1.94-10%）和顺-4,7,10,13,16,19-二十二碳六烯酸（C22:6n-3，3.31-31.03%）。n-3PUFA 的比例范围从环纹臂尾轮虫的 12.66%到欧洲无须鳕的 36.54%，而 n-6PUFA 的比例范围从大洋马鲛的 1.24%到鲻鱼的 12.76%。本研究结果表明，这些鱼类富含 n-3PUFA，尤其是二十碳五烯酸和二十二碳六烯酸。
