Effect of Seasons on Fatty Acid Composition of Laurencia obtusa (Hudson) J.V. Lamouroux, 1813 From Sinop Coast of the Black Sea
Öz
The aim of this study was to determine the fatty acid profile of Laurencia obtusa collected from the Sinop coast. The fatty acids profile were analyzed by GC/MS and their seasonal variation was studied. Along the sampling, it was identified 36 different fatty acids in L. obtusa. During the research, it was determined that the most abundant fatty acid was palmitic acid with values ranging from 33.78±1.03% in winter to 44.51±1.70% in summer. At the end of the study, it was determined that the season in which L. obtusa was richest in terms of PUFA and SFA contents was spring and in terms of MUFA content was autumn. In addition, in the study, It has been determined that the PUFA/SFA ratio in L. obtusa varied between 0.10% and 0.23% from winter to summer, and the total n-6/n-3 PUFA ratio changed between 1.14% and 2.37% from summer to autumn. It was determined that the atherogenicity index (AI) value changed between 1.75 and 1.97 from autumn to summer, and the thrombogenicity index (TI) value changed between 1.58 and 2.22 from winter to autumn. As a result of the research, it was revealed that the seasons have a significant effect on the fatty acid profile.
