Abstract
The acid glycosaminoglycans were extracted from the skins of young rats less than 1 day post partum. The isolated products were fractionated by a cetylpyridinium chloride–cellulose column technique and identified by chemical analysis, electrophoretic mobility and susceptibility to testicular hyaluronidase digestion. Hyaluronic acid (56%) dermatan sulphate (15.6%) and chondroitin 6-sulphate (9.1%) were the major components, but chondroitin 4-sulphate, heparan sulphate and heparin were also present, together with two further fractions tentatively suggested to be a heparan sulphate-like fraction and a dermatan sulphate fraction, both of short chain length or low degree of sulphation.
