Biochemical structures of LPG from L. braziliensis and L. infantum. Although Leishmania LPG shows a well conserved lipid anchor and oligosaccharide core structure, a wide range of polymorphisms of the composition of the sugar branch on the repeat units is well known. For L. braziliensis procyclic promastigote LPG, there is no substitution on the repetitive units while in L. infantum LPG there are different sugar branch substitutions of glucose oligosacharides that vary from one to three glucoses.
