Date of deprecation: 17:30, May 12, 2014
Reason for deprecation: Deprecate record: Hyaluronan is an oligiomeric/polymeric biomolecule, this record is likely the consequence of processing a file that tried to represent the mixture of these as their repeat unit

If you believe this record was deprecated in error, please use the Comment on this record button to contact the ChemSpider team.

Common reasons for deprecation are:
  • Chemically impossible structures (eg. incorrect valence atoms)
  • Lack of any linking data sources
  • Poor depiction of a structure that is already in ChemSpider
