  Abstract:

  The glycosaminoglycans from the skin and head cartilage of the   squid N. gouldi were isolated and characterized by constituent   disaccharide and neutral sugar anal., 13C NMR spectroscopy, anion   exchange, and size exclusion chromatog.  The   glycosaminoglycans from both tissues are chondroitin sulfate   species.  The skin consists principally of unsulfated but   relatively highly glycosylated material.  The chondroitin   sulfate from the head cartilage is more highly sulfated,   predominantly C-4,6diS (chondroitin sulfate E), with a higher   mol. wt. than the skin derived material but somewhat less highly   glycosylated.  To provide a std. for the assignment of the   13C NMR spectrum, C-4,6diS was chem. prepd. from bovine tracheal   chondroitin sulfate.  This showed that it is not possible to   distinguish between a mixt. of the monosulfates, C-4S and C-6S,   and the C-4,6diS by 1-dimensional and simple 2-dimensional 13C   NMR techniques.
