2-O-(beta-d-Glucuronyl)-7-O-(2-amino-2-deoxy-alpha-d-glucopyranosyl)-l-glycero-d-manno-heptose:a Constituent of the Bordetella pertussis Endotoxin

Abstract
The presence of bound D-glucuronic acid in the endotoxin of B. pertussis was demonstrated. The branched chain trisaccharide named in the title was isolated after hydrolysis of the endotoxin with 3 M HCl for 2 h at 100.degree. C. Its structure was established by chemical and enzymic degradation.
