  • a N-Acetylgalactosamine and N-acetylglucosamine are de-N-acetylated during the acid hydrolysis and are detected as galactosamine and glucosamine.

  • b Values are the means of triplicate samples ± standard deviations.

  • c The total is expressed as the mean percentage of total dry weight of the polymer from triplicate determinations.
