Table 4: Fatty acid (FA) profile and content of each fatty acid (expressed in mg g\({}^{-1}\)) of the four algae species studied. SFA—saturated fatty acids; MUFA—monounsaturated fatty acids; PUFA—polyunsaturated fatty acids; HUFA—highly unsaturated fatty acids; LA—linolenic acid. N corresponds to the number of different fatty acids found for each species. Results are expressed in mean \(\pm\) standard deviation (\(n=3\)). Statistically significant differences in the same fatty acid content among the species are expressed by letters above the bars (\({}^{\text{a}}\)\({}^{\text{b}}\)\({}^{\text{c}}\)\({}^{\text{d}}\)). Similar letters indicate no significant differences at the \(p\)-value ¡ 0.05 level. _Appl. Sci._**2021**, _11_, 10681  
Figure 2: n-MDS of the four species studied, regarding the fatty acid profile: _Laminaria ochroleuca_ (LO_R1, LO_R2, LO_R3), _Saccharina latissima_ (SL_R1, SL_R2, SL_R3), _Sacchariza polychides_ (SP_R1, SP_R2, SP_R3), and _Undaria pimmatifida_ (UP_R1, UP_R2, UP_R3). Group A is composed of LO_R1, LO_R2, and LO_R3 samples; group B is composed of SL_R1 and SL_R3 samples; Group C is composed of UP_R1, UP_R2, UP_R3, SP_R1, and SP_R2 samples.
