Biochemistry of Shellfish Lipids
VIII. Occurrence of Ceramide Mono- and Dihexoside in Corbicula, Corbicula sandai
From the Department of Chemistry, Faculty of Education, Shiga University Otsu, Shiga
The isolation and characterization of glycolipids (already reported as Fr. 1(1)) from the tissues of corbicula, Corbicula sandai, are described. Each glycolipid was purified by column chromatography on Florisil, cleaved by methanolic HC1 and the components were determined mainly by gas chromatography.
Ceramide monohexosides consisted of glucosyl-ceramide (77%) and galactosyl-ceramide (23%). The ceramide dihexoside was different from any glycolipids of higher animals in its mannose content in place of galactose. The tentative structure was proposed to be mannosylgluco-syl-ceramide.
