Abstract:
:Raman spectra have been determined for hyaluronan, chondroitin-4-sulfate, chondroitin-6-sulfate, aggrecan monomers and aggregates. The nature of the saccharides and the pattern of sulfation can be discerned. There were only small spectral changes with pH and ionic composition. Differences between hydroxyl vibrations, bulk water and solution conditions are shown. The spectrum of aggrecan is dominated by chondroitin sulfate contribution. The sulfation pattern and ratio of protein to glycosaminoglycan and the secondary structure of the core protein were determined.
