Hexadecylpalmitoyglycerol or ceramide is linked to similar glycophosphoinositol anchor‐like structures in Trypanosoma cruzi

The lipopeptidophosphoglycan from Trypanosoma cruzi is a glycosylated inositol‐phosphoceramide isolated from epimastigotes at the stationary phase of growth (4–5 days). We have now purified two similar glycoinositolphospholipids (glycoinositolphospholipid A and glycoinositolphospholipid B) from epim...

After alkaline hydrolysis, the lipids were analysed by GLC/MS. In glycoinositolphospholipid A the resulting lipids corresponded to 1‐O‐hexadecylglycerol and palmitic acid. The ceramide components in glycoinositolphospholipid B are sphinganine, palmitic acid and lignoceric acid.
