Abstract
The C-13 NMR signals of various even and odd agarose oligosaccharides with either D-galactose or 3,6-anhydro-alpha-L-galactose at the reduci ng end have been assigned. The chemical shifts in water of the agaro- and the neoagaro-oligosaccharides are compared and the influence of di methyl sulfoxide on the chemical structure of the agaro-oligosaccharid es is reported. The 3,6-anhydro-L-galactose residue at the reducing en d of agaro-oligosaccharides is in the hydrated form.
