Abstract
The major neutral glycosphingolipids from Trypanosoma cruzi ceramide mono- and dihexosides (CMH and CDH, respectively) were analysed after chromatographic purification using 1H 500 MHz nuclear magnetic resonance spectroscopy and fast atom bombardment mass spectrometry. The ceramide monohexoside fraction (CMH) contained both glucosyl- and galactosylceramides. After peracetylation, the CMH fraction was separated into 2 subfractions, CMH-COH and CMH-Cn, containing either hydroxy fatty acids or n-fatty acids. In the CMH-COH fraction glucose and galactose were present in a ratio of 2:1, whereas this ratio was 1:1 in the CMH-Cn fraction. The CDH fraction was identified as lactosylceramide with sphingosine as the long chain base and 16:0, 18:0, and 24:0, 24:4 fatty acids as major components.Entities:
