Prospholipid and fatty acid composition of two brachyuran decapod crustacea callinectes latimanus (Rathbun) and cardisoma armatum (herklots)
MetadataShow full item record
Preparative and analytical thin layer Chromatography have been used to purify and separate phospholipids from the total lipids of Callinectes latimanus (Decapoda: Portunidae) and Cardisoma armatum Decapoda: Gecarcinidae). Comparison of Rf values of standards with standard Rf values in the solvent system employed indicated the presence of phosphatidy 1 ethanolamine (PE; Rf = 0.61), phosphatidy 1 choline (PC; Rf =03.34), phophatidic acid (PA; Rf = 0.76) and phosphatidy 1 – N-methy 1 ethanolamine (PNME; Rf = 0.85). An unidentified spot with Rf = 0.93 was also detected. Gas liquid chromatography of the total lipid extract from the two Crustaceans indicated that the predominant saturated fatty acid in the two Crustaceans is palmitic acid (C16:0) with oleic acid (C18:1) occurring as the major unsaturated fatty acid. The probable role of phosphatidyl – N –methyl ethanolamine and the composition of the fatty acid methyl esters (FAME) are discussed......
