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