in the preceding paper in this journal , the major oligosaccharides obtained by endo-beta-galactosidase digestion of bovine corneal keratan sulphate were identified as a neutral disaccharide , glcnac beta 1-3gal , and sulphated di- , tetra- , hexa- , octa- and decasaccharides based on the sequence ( -3/4glcnac beta 1-3gal beta 1- ) n having 1 , 3 , 5 , 7 and 9 sulphate groups , respectively .
