is metabolized by the GPIpathway to yield products up to and including W and Z.Glycolipid C synthesis is inhibited by metabolite(s)of the GPI analoguesTo ascertain whether it is compound 3 (the deprotected formof compound 1) or one of its metabolites that inhibits theformation of glycolipid C, we pre-labelled a trypanosome cell-free system with GDP-[3H]Man (to form labelled glycolipid A0and y) an
