The aim of this study is to determine the composition and percentage of fatty acids in marine algae species [Codium fragile (Suringar) Hariot, Ulva intestinalis Linnaeus (Synonym: Enteremorpha intestinalis Linnaeus-Nees), U. lactuca Linnaeus] and freshwater algae species [Cladophora fracta (O.F Müller ex Vahl) Kützing and Spirogyra weberi Kützing] and to compare species with each other. The algal samples were collected from five different areas along The Black Sea coast (Trabzon). Freshwater algae were also collected from Gümenek area of Yeşilırmak River, Tokat. The composition of fatty acids were determined by gas chromatography (GC). In all algae samples, palmitic acid (PA) was predominantly found. The palmitic acid levels in freshwater algae were lower than in marine algae. In S. weberi and C. fracta, monounsaturated fatty acid (MUFA) levels were higher than the other algae. U. lactuca had 16.38% oleic acid (OA), and 77.03% saturated short-chain fatty acid. Linolenic acid (LA) was determined in high levels (9.75%) in S.weberi. In U. intestinalis, 19.09% saturated short-chain fatty acid and 80.73% saturated long-chain fatty acid were found. In all species, except U. intestinalis, saturated short-chain fatty acids were higher than saturated long-chain fatty acids. In S. weberi, the unsaturated fatty acids (UFA) were higher than saturated fatty acids (SA). Likewise, the 16:1 ω7 fatty acid in S.weberi is noteworthy. The unsaturated fatty acid levels detected in freshwater algae were greater than marine algae, and levels of palmitic acid in freshwater algae were less than marine algae.
