Table 3.
Fatty acid profile of each fatty acid (expressed in mg·g−1 of dried algae) of Sargassum muticum, Undaria pinnatifida, Colpomenia peregrina, Gracilaria gracilis, Calliblepharis jubata, and Asparagopsis armata. α-LA alpha linoleic acid; γ-LA—gamma linoleic acid; ARA—arachidonic acid; EPA—eicosapentaenoic acid; DHA—docosahexaenoic acid. Results are expressed in mean ± standard deviation. The sum of fatty acids’ (FA) content that compose each class (SFA—saturated fatty acids; MUFA—monounsaturated fatty acids; PUFA—polyunsaturated fatty acids; HUFA—highly unsaturated fatty acids), the ratio of omega 6/omega 3 and the N—diversity in FA molecules have been highlighted with bold format in the respective table lines.
