Salinity induces unique changes in lipid classes and fatty acids of the estuarine haptophyte Diacronema vlkianum

Abstract Background: Lipidome-wide metabolites may be useful biomarkers of pregnancy outcomes. We sought to characterize maternal lipidomic signatures associated with preterm birth and neonatal anthropometric parameters. Methods: Plasma samples were collected 24-28 weeks gestation, and lipidomic profiling was quantified using high-performance liquid chromatography tandem mass spectrometry. Lipid metabolites were analyzed individually and as whole lipid classes and subgroups based on degree of hydrocarbon chain saturation. Associations were estimated using linear and logistic regression.Results: After false discovery adjustment (q<0.15), four plasmenyl-phosphatidylethanolamines and three free fatty acids associated with increased risk for spontaneous preterm birth. Five phosphatidylinositols, two phosphatidylglycerols, and one phosphatidic acid were associated with large for gestational age neonates. The saturated plasmenyl-phosphatidylethanolamines held the association with increased risk for spontaneous preterm birth. Both the mono- and poly-unsaturated free fatty acids held the association for increased risk for spontaneous preterm birth. Mono- and poly-unsaturated phosphatidylinositols were associated with large for gestational age neonates. Whole lipid classes (plasmenyl-phophatidylcholines and plasmenyl-phosphatidylethanolamines) were associated with increased risk for large for gestational age at delivery.Conclusions: This study provides evidence that finer omics-scale analysis of the maternal lipidome may be more informative biomarkers of pregnancy outcomes compared to whole class level lipid analysis.

This study studied the content and composition of the total lipid, lipid classes and fatty acids in 13 brown seaweed Sargassum species collected from Con Dao and Van Phong, Vietnam. The total lipid has a low content and varies among species from 0.10–1.70% of the fresh weight. From 13 species, seven lipid classes including polar lipid (Pol), free fatty acids (FFA), sterol (ST), hydrocarbon and wax (HW), triacylglycerol (TG), diacylglycerol (DG), and monoalkydiacylglycerol (MADG). Using the GC-FID technique, we have identified 29 fatty acids classified into 3 groups of saturated fatty acid, monounsaturated fatty acids, polyunsaturated fatty acids with an average content of 44.93%, 24.57% and 27.44%, respectively. Among those, many value fatty acids have been detected with high content such as C18:3n-3, C20:4n-6, 20:5n-3, and 22:6n-3. The lipid of 13 brown seaweed Sargassum species also fully contains omega-3,6,9 fatty acids with the content of 9.28%, 16.28% and 16.63%, respectively.

Tripneustes Gratilla

ABSTRACT – HCTN 06The Sea urchin Tripneustes gratilla (Linnaeus, 1758) is a famous species of invertebrate member of the phylum Echinodermata of marine animals living in shallow tropical water. In Viet Nam, it is usually called by the name of yellow sea urchin. This species is mentioned much about its economic and commerce properties. Recently, many researchers have been paying attention to sea urchin because of its positive effect on human health. In terms of medicine and nutrition, the egg of yellow sea urchin was rich in Polyunsaturated Fatty Acids (PUFAs) and essential amino acids. In this research, we focused on determining the total lipid contents, the components of lipid classes and the compositions and contents of fatty acids, amino acids from the body and the egg of the yellow sea urchin T. gratilla (Linnaeus, 1758) collected in Hon Tam, Nha Trang, Khanh Hoa, Viet Nam in 2016. Although the yellow sea urchin T. gratilla has low percentage of total lipid in fresh weigh basis, they are full of essential lipid ingredients such as Wax and Hydrocabon (H + W), Triacylglycerol (TG), Monodiacylglycerol MDAG, Free Fatty Acid (FFA), sterol (ST), and Polar Lipid (PL). In both egg and body samples palmitic acid (16:0) was the most abundant fatty acid with the proportion of about 25%. In addition, arachidonic acid (20:4n-6) is dominent Omega-6 fatty acid in the Monounsaturated Fatty Acid group (MUFA). Furthermore, the research result also showed the very high percentages of omega-3 fatty acids in the egg and body of T. gratilla, with the total contents of 13.97% and 20.67% respectively, especially the presence of eicosapentaenoic fatty acid (C20:5n-3, EPA), a very valuable fatty acid. By the HPLC method, the research also found 17 amino acids in the egg and body of T. gratilla with the existence of 7 essential amino acids.Keywords: Tripneustes gratilla, lipid classes, yellow sea urchin, echinodermata, fatty acid content.
