Abstract:
A detailed knowledge of the primary structure of neutral glycosphingolipids isolated and purified from Trypanosoma dionisii has been elucidated using a combination of techniques--as column chromatography, HPTLC and GC-MS together with fast atom bombardment spectrometry. The ceramide monohexoside fraction (CMH) contained both glucosyl- and galactosylceramides in a ratio of 1:1, sphingosine and as fatty acyl groups mainly C-24 saturated and 2-hydroxy fatty acids. A close similarity between Trypanosoma cruzi and T. dionisii monohexosylceramides was reported.
