Structural studies on the oligosaccharide moety of the lipopeptidophosphoglycan from Trypanosoma cruzi
The structure of the carbohydrate moiety of the lipopeptidophosphoglycan from Trypanosoma cruzi was studied by 13C NMR spectroscopy and by methylation analysis of the original and of an acid‐degraded sample. An oligosaccharide, consisting of 2‐O‐substituted and 6‐O‐substituted mannoses, which is lin...

| Sumario: | The structure of the carbohydrate moiety of the lipopeptidophosphoglycan from Trypanosoma cruzi was studied by 13C NMR spectroscopy and by methylation analysis of the original and of an acid‐degraded sample. An oligosaccharide, consisting of 2‐O‐substituted and 6‐O‐substituted mannoses, which is linked to the ceramide, was separated by partial acid hydrolysis from an external chain that contained 3‐O‐substituted mannopyranosyl residues. β‐D‐Galactofuranosyl terminal units are attached to position 3 of (1 → 2)‐linked mannopyranose. Besides the previously reported monosaccharide components (mannose, galactose, glucose and glucosamine), ribose was identified in a partial acid hydrolysate of the lipopeptidophosphoglycan. The last three sugars are minor components and their oganization into the overall structure of the lipopeptidophosphoglycan has not been determined. Copyright © 1985, Wiley Blackwell.
