Oleic acid has the highest percentage of MUFA in brown seaweeds (_P. indica_ and _T. ornata_), in accordance with the results of CAF et al. [77], reported that in brown algae (_Toania atomaria_ and _Padina pavonica_), oleic acid made up the largest portion of the MUFA. Five polyunsaturated essential fatty acids (PUFA) were appeared in (Table 3) C18:2u6 (linoleic acid), C18:3 \(\omega\)3 (\(\alpha\)-linolenic acid), C20:4 \(\omega\)6 (archidonic acid), C20:5 \(\omega\)3 (Eicosapentaenoic acid) and C22:6 \(\omega\)3 (Docosahexaenoic acid). Brown species (_T. ornata_ and _P. indicia_) attained the highest percent of the total polyunsaturated fatty acids, followed by red species S. _scinaioides_ and _L. obtusa_ recorded the lowest percent. The amount of \(\alpha\)-Linolenic acid and linoleic acid in the studied seaweeds was notably higher than those reported in _Porphyna_ sp. and _Palmaria_ sp. (Table 3). The original value of 1 for the \(\omega\)6/\(\omega\)3 ratio involved the balance of intake of both PUSA \(\omega\)6 and \(\omega\)3 fatty acids [79]. The ratio of \(\omega\)6/\(\omega\)3 was 0.78, 0.74, 0.70, and 0.33 for _P. indica_, _T. ornata_, _L. obtusa_, and _S. scinaioides_, respectively. This ratio should not exceed 10 in diets, according to the World Health Organization (WHO) [76], meaning that the seaweeds under investigation are edible after further research. Diverse levels of \(\omega\)3 fatty acids may explain why the seaweeds studied are used in different ways to reduce the risk of multiple sclerosis, inflammation, diabetes, cancer, and coronary heart disease. According to [PERSON] [81], omega-3 fatty acids provide health benefits, including benefits for inflammatory bowel disease, cancer, psoriasis, and rheumatoid arthritis. In recent academic publications, the relevance of the \(\omega\)6/\(\omega\)3 ratio has been severely debated. PUFAs were found to play an important role in cell and tissue metabolism, such as controlling cell membrane fluidity, electron and oxygen transport, and thermal adaptation, and may lower the risk of coronary heart disease [82]. The fatty acid pattern of _L. obtusa_ was nearly identical to that of _Porphyna_ sp., but higher in total saturated and monounsaturated fatty acids and lower in palmitic acid (SFA). The species _L. obtusa_ contains the highest percentage of the total fatty acids, while _T. ornata_ has the lowest content of the total fatty acids.
