Data for: The macroalgal ensemble of Golfo Nuevo (Patagonia, Argentina) as a potential source of valuable fatty acids for nutritional and nutraceutical purposes

The appendix contains the fatty acid profile of fifteen seaweed species from Patagonia.
Sixty nine different fatty acids were detected; most of them at trace levels and/or in specific samples only. Five were branched-chain FA with 11-14 carbon chain length and another three were hydroxylated FA with 16-22 carbon chain length. Thirteen of the detected compounds were identified to their chain length and number of double bonds, but could not be determined the double bonds position. Five of the detected compounds were only identified to their chain length. One compound could not be identified in chain length, number and position of double bonds. One of the hydroxylated FA could not be identified in the OH and double bond position. In all cases, cis or trans isomers were confirmed only if the compounds were present in the standards used. For further analysis, a database with 31 FA was constructed by filtering from the raw database those FA whose proportion exceeded 2% in, at least, one sample. This procedure excluded 65% of the detected compounds from the analysis, but its content only accounted for 2.3% of the total FA.

本附录收录了来自巴塔哥尼亚的十五种海藻的脂肪酸谱。检测到六十九种不同的脂肪酸；其中大部分仅以痕量存在或仅在某些特定样本中发现。五种为分支链脂肪酸，碳链长度为11-14个碳原子，另外三种为羟基脂肪酸，碳链长度为16-22个碳原子。检测到的十三种化合物被确认为其碳链长度和双键数量，但无法确定双键的位置。五种检测到的化合物仅被确认为其碳链长度。一种化合物无法确定其碳链长度、双键数量和位置。一种羟基脂肪酸无法确定其羟基和双键的位置。在所有情况下，仅当化合物存在于所使用的标准品中时，才能确认顺式或反式异构体。为了进一步分析，通过从原始数据库中筛选出在至少一个样本中比例超过2%的脂肪酸，构建了一个包含31种脂肪酸的数据库。此过程排除了检测到的65%的化合物，但其含量仅占总脂肪酸的2.3%。
