this is the first demonstration of in vitro synthesis of the glcnac beta 1-3galnac disaccharide and of the glcnac beta 1-3- ( glcnac beta 1-6 ) galnac trisaccharide , two of the four major core types found in mammalian glycoproteins of the mucin type , i.e. , those containing oligosaccharides with galnac-alpha-serine ( threonine ) linkages .
