title: Phospholipid fatty acid composition of Gorgonia mariae and Gorgonia ventalina.
abstract: The phospholipid fatty acid composition of the Caribbean gorgonians Gorgonia mariae (Bayer) and Gorgonia ventalina (Linnaeus) is described for the first time. The main phospholipids identified were phosphatidylethanolamine, phosphatidylcholine, and phosphatidylserine. The main fatty acids were 14:0, 16:0, 18:3(n-6), 18:4(n-3), 18:2(n-6), 20:4(n-6), 22:6(n-3), and 24:5(n-6). In both G. mariae and G. ventalina n-6 polyunsaturated fatty acids predominated over the n-3 family. In addition, the 7-methyl-6(E)-hexadecenoic acid was identified in both gorgonians. The occurrence of tetracosapolyenoic fatty acids in the genus Gorgonia is also reported for the first time.
