with n-fluoroacetyl-d- [ 1- ( 14 ) c ] glucosamine as precursor , a hyaluronate component was separated that on enzymic degradation by glycosidases ( hyaluronidase , beta-glucuronidase and n-acetyl-beta-hexosaminidase ) yielded a ( 14 ) c-labelled oligosaccharide fraction together with n-acetyl-d- [ 1- ( 14 ) c ] glucosamine and n-fluoroacetyl-d- [ 1- ( 14 ) c ] glucosamine , consistent with some exchange of n-acetyl groups having occurred .
