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...
