Distinct fatty acid profile of ten brown macroalgae
Open accessAbstract
It is widely accepted that the consumption of ω-3 polyunsaturated fatty acids has beneficial effects on human health. In this work, ten brown macroalgae species collected along the Portuguese west coast were studied for their fatty acids composition by GC-MS after alkaline hydrolysis and derivatization. The results of this survey showed that different macroalgae from the same region display distinct fatty acids profile. Concerning ω-3 polyunsaturated fatty acids, eicosapentaenoic acid was found in all but one species. Additionally, some species contained docosahexaenoic acid. Linoleic acid, an essential fatty acid of the ω-6 series, was present in all studied macroalgae. Fucus spiralis L. exhibited the highest amounts of monounsaturated fatty acids and of polyunsaturated fatty acids of the ω-3 and ω-6 series. The ω-6/ω-3 ratio in half of the studied species was lower than 1. This information reinforces the potential application of some brown macroalgae as dietary sources of polyunsaturated fatty acids.

Macroalgae contain larger amounts of unsaturated fatty acids than saturated, and because of that, they exhibit acetylcholinesterase inhibition, which can provide protection from neurodegenerative disorders.
“Macroalgae contain larger amount of unsaturated fatty acids than saturated [23,24], and because of that, they exhibit acetylcholinesterase inhibition, which means that they can provide protection from neurodegenerative disorders [25].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
