3.2.1.103 keratan sulfate + H2O from bovine cornea Bacteroides fragilis keratan oligosaccharides more than 75% of the oligosaccharides are sulfated unbranched poly(N-acetyllactosamine) sequences, (-3/4GlcNAcbeta1-3Galbeta1-)n. SO3-beta1-3Gal accounts for almost 35% of the oligosaccharide material while 40% consists of four oligosaccharides, unbranched tetrasaccharides, hexasaccharides, octasaccharides and decasaccharides of poly(N-acetyllactosamine)type, having 3, 5, 7 and 9 sulfate residues respectively. A sulfate residue is attached to the C6 position of each N-acetylglucosamine and each internal galactose residue of the four oligosaccharides ?
