Structural analysis of a unique hybrid-type ganglioside with isoglobo-, neolacto-, and ganglio-core from the gills of the Pacific salmon (Oncorhynchus keta)
چکیده انگلیسی
Monosialosyl gangliosides from the gills of the Pacific salmon, Oncorhynchus keta, have been prepared by solvent extraction and DEAE-Sephadex column chromatography. The unknown acidic glycolipids (M14 and M15) with slower mobility than GM1a on thin-layer chromatography were separated by Iatrobeads column chromatography and were characterized by compositional analysis, methylation analysis, chemical, and enzymatic degradation, negative-ion LSIMS, and 1H nuclear magnetic resonance spectroscopy. Both M14 and M15 contained a same oligosaccharide core with isoglobo-, neolacto-, and ganglio-series as follows:The only difference between M14 and M15 was in fatty acid acylation. Analysis of the fatty acids indicated a predominance of C24:1 fatty acid in M14 and shorter chain saturated fatty acids, C14:0 and C16:0, in M15.
