Lipidomics as a new approach for the bioprospecting of marine macroalgae — Unraveling the polar lipid and fatty acid composition of Chondrus crispus

摘要: Abstract Marine macroalgae, or seaweeds, have been used for direct human consumption, as additives in the food industry, and fertilizers agriculture. The fatty acid composition of several species macroalgae has extensively studied, considering their nutritional value phylogenetic characterization. However, polar lipid components which include compounds with important nutraceutical bioactive properties, are still very poorly studied at molecular level. Herein, it is reported, first time, a lipidomic study on red seaweed Chondrus crispus, namely its through hydrophilic interaction liquid chromatography — electrospray ionization mass spectrometry (HILIC–ESI–MS), an approach to better understand valuable properties provided from lipidic components. main groups identified glycolipids (sulfoquinovosyldiacylglycerols digalactosyldiacylglycerols), glycosphingolipids bearing ceramide backbones (galactosylceramides), inositolphosphoceramides, glycerophospholipids (phosphatidylcholines, lyso-phosphatidylcholines, phosphatidic acids, phosphatidylglycerols lyso-phosphatidylglycerols), betaine lipids, well some phytyl derivatives, chlorophylls pheophytins. This lipidomic-based envisaged promising algae fingerprint, required metabolism, dependence environmental conditions, also valorization edible products source compounds.
