NMR spectroscopic investigation of agarose oligomers produced by an alpha-agarase. The 13C NMR signals of various even and odd agarose oligosaccharides with either D-galactose or 3,6-anhydro-alpha-L-galactose at the reducing end have been assigned. The chemical shifts in water of the agaro- and the neoagaro-oligosaccharides are compared and the influence of dimethyl sulfoxide on the chemical structure of the agaro-oligosaccharides is reported. The 3,6-anhydro-L-galactose residue at the reducing end of agaro-oligosaccharides is in the hydrated form.
