RESUMO
A hydrophobic fraction isolated from trypomastigotes of Trypanosoma cruzi is being characterized using immunological and chemical techniques. The lipopeptidophosphoglycan (LPPG) was identified in this fraction since it gave a positive reaction with anti-LPPG rabbit serum and had similar structural features such as the presence of ceramide as the lipid moiety, furanoic galactose, and a glycan moiety consistent with that obtained from an authentic sample of epimastigote LPPG, as judged by thin-layer chromatography. Furthermore, the hydrophobic fraction contained other glycolipids with different structural features. The lipid moiety of these compounds is alkylglycerol rather than a ceramide, the carbohydrate chain appears to be less complex than that in LPPG and no reactivity was observed towards an anti-LPPG serum
