The positions of the OAc groups in the alpha-GlcA, beta-ManNAc, and alpha-Glc residues of the native 9V PS were established using 2D-n.m.r. and chemical shift arguments, and the relative proportions of different O-acetylated species were estimated by integration of well-resolved 1H-n.m.r. signals. The locations of the OAc substituents differ from those previously reported.
