Barrios Montilla, Jorge IDENTIFICACIÓN Y CUANTIFICACIÓN DE ÁCIDOS GRASOS PRESENTES EN TRES MACROALGAS DE ISLA CARIBE, ESTADO SUCRE, VENEZUELA Mendeley Data In the present work, the fatty acids present in three Rhodophyta macroalgae collected in March 2001 on the Caribbean island (Sucre state, Venezuela): Centroceras clavulatum, Hypnea valentiae and Gymnogongrus tenuis, were studied. Lipid extraction was carried out by the Overturf and Dryer method, for the characterization and quantification of fatty acids (FA) a gas chromatograph was used. The study showed the occurrence of nine saturated fatty acids:13:0, 14:0, 15:0,16:0, 18:0, 19:0, 20:0, 22:0 and 24:0, two monounsaturated fatty acids:16:1ω-7 and 18:1ω-7, and five polyunsaturated fatty acids:18:2ω-6, 18:4, 20:2, 20:5ω-3 and 22:6ω-3. The algae C. clavulatun presented 13 fatty acids, and the other two algae presented 9 FA, resulting the FA 16:0, 18:2ω-6, 20:2, 20:5ω-3 and 22:6ω-3 common for the three species. In red algae, the most abundant fatty acid is eicosapentaenoic acid, but in this work docosahexaenoic acid stood out due to its high percentages for the algae studied, which is an important difference with rhodophyceans from other regions that could be attributed to environmental factors. Only marine algae can biosynthesize essential fatty acids, the presence of significant amounts of polyunsaturated fatty acids 20:5n-3 and 22:6n-3 in the species analyzed gives it value in humans and animals diets Red Algae Saturated Fatty Acid Maza-Wuitter, Arelys Dataset doi:10.17632/c4zntdztg8.1 oai:data.mendeley.com/c4zntdztg8.1 Creative Commons Attribution 4.0 International http://creativecommons.org/licenses/by/4.0 https://data.mendeley.com/datasets/c4zntdztg8 2023-10-31T20:31:44Z
