J Isolation and identification of phospholipid molecular species in a wild marine shrimp Penaeuskerathurusmuscle and cephalothorax Journal Article In: Chemistry and Physics of Lipids, vol. 152, pp. 104-112, 2008, ((I F: 2.861),12ετεροαναφορές). Abstract | Links | BibTeX | Ετικέτες: fatty acids, P. kerathurus, Phosphatidylcholine, Phosphatidylethanolamine, Phospholipids @article{Miniadis-Meimaroglou2008, The concentration of TL in Penaeus kerathurus muscle and cephalothorax was 1.03 ± 0.04 (75.9 ± 0.8% of which was PhL) and 2.36 ± 0.07% (45.5 ± 0.8% of which was PhL) of the wet tissue, respectively. The phosphatidylethanolamine represented 26.4 ± 0.6% (85.6% diacyl- and 14.4% alkyl-acyl- or alkenyl-acyl-analogues) of muscle and 24.7 ± 0.2% (90.7% diacyl- and 9.3% alkyl-acyl- or 1-alkenyl-acyl-analogues) of cephalothorax phospholipids while the phosphatidylcholine represented 57.1 ± 0.6% (86.9% diacyl- and 13.1% alkyl-acyl- or alkenyl-acyl-analogues) of muscle and 47.2 ± 0.4% (89.1% diacyl- and 10.9% alkyl-acyl- or 1-alkenyl-acyl-analogues) of cephalothorax phospholipids, respectively. The main fatty acids of phosphatidylethanolamine were C16:0, C18:0, C18:1 ω − 9, C20:4 ω − 6, C20:5 ω − 3, C22:6 ω − 3 and of phosphatidylcholine were C16:0, C18:0, C18:1 ω − 9, C20:4 ω − 6, C20:5 ω − 3. Low percentages of 2-OH C14:0 and cyclo-17:0 fatty acids were also determined. Phosphatidylethanolamine were found to contain a significantly (P < 0.05) higher percentage of polyunsaturated fatty acids compared to phosphatidylcholine. The ω − 3/ω − 6 ratio in muscle phosphatidylethanolamine and phosphatidylcholine was significantly (P < 0.05) higher to the ones of cephalothorax. |

Abstract | Links | BibTeX | Ετικέτες: cephalothorax, fatty acids, Palinurus vulgaris, Phospholipids @article{Garofalaki2006, The total lipids of muscle and cephalothorax of Mediterranean lobster Palinurus vulgaris were found to be 1.0% and 2.4% of the wet tissue of which the phospholipids represented 66.5% and 47.5%, respectively. The main PhL saturated, monounsaturated and polyunsaturated fatty acids in muscle and cephalothorax were C16:0, C18:0, C18:1omega-9, C18:1omega-7, C20:4omega-6, C20:5omega-3 and C22:6omega-3. 2-OH C14:0 and cyclo-17:0 fatty acids were also identified though in low percentages. The main individual PhL in muscle were found to be phosphatidylcholine (53.5%), 72.0% of which corresponded to the structure of 1,2-diacyl-glycerocholine while the rest 28.0% to 1-O-alkyl-2-acyl-glycerocholine or 1-O-(1-alkenyl)-2-acyl-glycerocholine and phosphatidylethanolamine (19.3%), 75.0% of which corresponded to the structure of 1,2-diacyl-glyceroethanolamine and 25% to 1-O-alkyl-2-acyl-glyceroethanolamine or 1-O-(1-alkenyl)-2-acyl-glyceroethanolamine. Cephalothorax main PhL were found to be PC and PE (66.4% and 18.8%, respectively). In muscle and cephalothorax PC omega-3 fatty acids amounted 7.78% and 8.60%, while in PE amounted 30.77% and 23.65% respectively. Furthermore, in both tissues PhL, cardiolipine phosphatidylserine, phosphatidylinositol, sphingomyelin and lysophosphatidylcholine, were also found. |

Sinanoglou, V. J.; Miniadis-Meimaroglou, S. Phospholipids from edible Mediterranean cephalopods Journal Article In: Z. Naturforsch, vol. 55c, pp. 245-255, 1999, ((I F: 0.709) 14ετεροαναφορές). Abstract | Links | BibTeX | Ετικέτες: cephalopods, Phospholipids @article{Sinanoglou1999, Polar lipids of the cephalopods Eledone moschata, Sepia officinalis and Todarodes sagittatus mantle, represent 50.5%, 66.1% and 74.2% of wet tissue respectively. On the other hand the polar lipids of these three species of cephalopods constitute of 80.8%, 94.8% and 93.7% of phospholipids, respectively. The main phospholipids identified were phosphatidylcholine (52.2, 51.3 and 58.4% of total phospholipids respectively in the above mentioned species), phosphatidylethanolamine (18.1, 19.7 and 23.9%), sphingomyelin (10.7, 15.2 and 6.7%), lysophosphatidylcholine (3.1, 3.8 and 1.8%) and the unusual lipid ceramide aminoethylphosphonic acid (15.9, 10 and 9.2%). The 56.8% of phosphatidylcholine in Eledone moschata, the 46% in Sepia officinalis and the 74.1% in Todarodes sagittatus refer to the structure of 1,2-diacyl-glycerocholine and the remaining percentage refer to the structure of 1-o-alkyl-2-acyl-glycerocholine or 1-o-alkyl-lenyl- 2-acyl-glycerocholine. The 87.2% of phosphatidylethanolamine in Eledone moschata, the 81% in Sepia officinalis and the 90.7% in Todarodes sagittatus refer to the structure of 1,2-diacyl-glyceroethanolamine and the remaining percentage refer to the structure of 1-o-alkyl-2-acyl-glyceroethanolamine or 1-o-alkyl-1-enyl-2-acyl-glyceroethanolamine. The major saturated fatty acids in phosphatidylcholine and phosphatidylethanolamine were C16:0 (30.3-67.5% and 23.2-54.5% ) and C18:0 (3.6-17% and 15.4-28% ), respectively, while the major unsaturated fatty acids in these lipids were C18:1n-9, n-7 (1.0-7.3% and 5.3-10.5% ), C20:5n-3 (1.5-9.8% and 4,5-15.8% ) and C22:6n-3 (12.5-42.0% and 7 .0 - 11.3%), respectively. |
