Glycosphingolipids mannose-containing

Ogawa and coworkers have also extensively described synthetic studies on glycoprotein oligosaccharides and mannose-containing glycosphingolipids using similar reactions [26,27, 28,29] (O Scheme 9). For instance, the reaction of 14 with disaccharide 15 afforded 16 (o = 1.1 1), which was used as the key intermediate in their first chemical synthesis of a sialic acid-containing complex-type undecasaccharide [30]. 

Complex plant sphingolipids, the phyto-glycosphingolipids, which contain glucosamine, glucuronic acid and mannose linked to the ceramide via phosphorylinositol, were isolated and characterised from seeds initially, but related compounds are also known to be present in other plant tissues and in fungi.

Neutral glycosphingolipids containing D-mannose have been extracted from whole tissues of the fresh-water bivalve Corbicula sandai. Chemical, enzymic, and physical methods were used to characterize two novel glycolipids, viz. jS-D-mannopyranosyl-(l -s- 4)-D-glucopyranosylceramide and a-D-mannopyranosyl-(1 -> 4)-j8-D-mannopyranosyl-(l 4)-D-glucopyranosylceramide, The compositions of the sialosphingolipids of sea-urchin eggs and spermatozoa have been...
