N2 - Skeletal keratan sulphate has been fragmented using the enzyme keratanase II, and the complete 13C chemical shift data are reported for the four tetrasaccharides which derived from the repeat region. They have the structures: Galβ(1–4)GlcNAc(6S)β(1–3)Galβ(1–4)GlcNAc(6S)-ol, Gal(6S)β(1–4)GlcNAc(6S)β(1–3)Gal(1–4)GlcNAc(6S)-ol, Galβ(1–4)GlcNAc(6S)β(1–3)Gal(6S)β(1–4)GlcNAc(6S)-ol, and Gal(6S)β(1–4)GlcNAc(6S)(1–3)Gal(6S)β(1–4)GlcNAc(6S)-ol, where GlcNAc(6S)-ol represents N-acetyl-glucosaminitol-6-O-sulphate. The value of these data for microstructural analysis of undegraded keratan sulphate samples using 13C-NMR spectroscopy is discussed with respect to galactose sulphation levels and the block sulphation structure.
