... allowing an under-standing of species, tissue, age and pathology relateddifferences and the estimation of changes in CS⁄ DSabundance and composition. However, the reduction of the polymer to its ... GalNAc6S(b1–4)GlcA(b1–3)GalNAc4S-ol and GalNAc6S(b1–4)GlcA(b1–3)GalNAc6S-ol. The full assignment of all signals in the NMRspectra are given, and these data permit the further characterization of CS ⁄ DS chains and their ... diverse tissue sources, fromtissues of differing ages and also within a singlechain. Enhanced availability of data to facilitate the characterization of these structures is therefore of value.GAGs...
