In the fatty acid composition of total lipid of the soft coral Bebryce sp., the concentration of unsaturated fatty acid predominates. The composition of saturated fatty acids is very diverse, including all saturated fatty acids from C14 to C26. The unsaturated fatty acids with high concentration are C20: 4n-6, 20:5n-3, 22:6n-3, 24:5n-6, 26:3n-6, 26:2n-6, 26:2n-7, 28:3n-6. In the fatty acids composition of the studied coral, there is presence of characterized fatty acids for the existence of sponges C25-C28 (demospongic fatty acids) with total content 29,86%. Most of the Bebryce coral species do not have zooxanthellae, therefore, in the fatty acids composition, either it is lack or contains only a small amount of markers fatty acids for zooxanthellae such as 18:5n-3, 18:4n-3, 18:3n-6, 20:4n-3. In the phospholipid content of the soft coral Bebryce sp., there is presence of characterized classes for Cnidarian animals such as phosphatidylethanolamine (PE), phosphatidylchonline (PC), phosphatidylserine (PS), phosphatidylinositol (PI), phosphonolipid is ceramide aminoethylphosphonate (CAEP). PC account for the highest concentration (37,20% of total phospholipid). The molecular species of phospholipid classes of Bebryce sp. for the first time were investigated. In the results, there we 60 phospholipid molecular species identified in 5 classes. The molecular species with high content in the classes were PE 20:4/18:1e, PE 20:4/19:1, PC 20:4/18:0e, PC 20:4/16:0e, PS 24:5/18:0e, PI 24:5/18:0, CAEP18:2base/16:0 and CAEP 18:1base/16:0.

In this report, by a high performance liquid chromatography (HPLC) - high resolution mass spectrometry (HRMS) method, 7 molecular species of phospholipid in the polar lipid class were identified including phosphatidylinositol (PI) and phosphatidylglycerol (PG). The PI 32:0 (16:0/16:0) and PG 34:3 (16:1/18:2) molecular species have the highest content. PI molecular species are mainly formed by saturated fatty acids (16:0, 18:0) and only one polyunsaturated fatty acids C20:4, while PG species are formed by unsaturated fatty acids (16:1, 18:2 and 18:3) and only one saturated fatty acid C16:0.

This study aims to analyze compositions of fatty acids and phospholipid molecular species in the hard clams Meretrix lyrata (Sowerby, 1851) harvested from Cua Lo beach, Nghe An province, Viet Nam. Total lipid of hard clams Meretrix lyrata occupied 1.7 ± 0.2% of wet weight and contained six classes: hydrocarbon and wax (HW), triacylglycerol (TAG), free fatty acids (FFA), sterol (ST), polar lipid (PoL), and monoalkyl diacylglycerol (MADAG). Among the constituents, the proportion of PoL accounted was highest, at 45.7%. In contrast, the figures for MADAG were lowest, at 1.3%. Twenty-six fatty acids were identified with the ratios of USAFA/SAFA was 2. The percentage of n-3 PUFA (ω-3) and n-6 PUFA (ω-6) was high, occupying 38.4% of total FA. Among PUFAs, arachidonic acid (AA, 20:4n-6), eicosapentaenoic acid (EPA, 20:5n-3), docosapentaenoic acid (DPA, 22:5n-3), and docosahexaenoic acid (DHA, 22:6n-3) accounted for 3.8%, 7.8%, 2.2% and 12.0% of total lipid of the clam respectively. Phospholipid molecular species were identified in polar lipids of the clams consisting six types: phosphatidylethalnolamine (PE, with 28 molecular species), phosphatidylcholine (PC, with 26 molecular species), phosphatidylserine (PS, with 18 molecular species), phosphatidylinositol (PI, with 10 molecular species), phosphatidylglycerol (PG, with only one molecular species), and ceramide aminoethylphosphonate (CAEP, with 15 molecular species). This is the first time that the molecular species of sphingophospholipid were determined, in Meretrix lyrata in particular, and for clams in general. Phospholipid formula species of PE and PS were revealed to comprise two kinds: Alkenyl acyl glycerophosphoethanolamine and Alkenyl acyl glycerophosphoserine occupy 80.3% and 81.0% of total PE and PS species, respectively. In contrast, the percentage of diacyl glycero phosphatidylcholine was twice as high as that of PakCho in total PC, at 69.3, in comparison with 30.7%. In addition, phospholipid formula species of PI and PG comprised only diacyl glycoro phospholipids. PE 36:1 (p18:0/18:1), PC 38:6 (16:0/22:6), PS 38:1 (p18:0/20:1), PI 40:5 (20:1/20:4), PG 32:0 (16:0/16:0) and CAEP 34:2 (16:2/d18:0) were the major molecular species.
