摘要
Hyaluronan is a kind of polysaccharide with high molecule weight, hs structure is relatively complicated and tertiary structure exists among the HA molecules when reaching to o certain solution concentration . FT- IR spectrum has been acquired to shou the groups and their ascription in HA. The results of FT-IR spectrum in this essay accords well with that issued by ASTM. As to the newly appearing absorption peaks, sensible explanation has been given, In ADDITION , Ramon spectrum has been employed as a proof for the result of the FT-IR spectnun. Based on the preliminary acknowledge of the functional groups in HA, circular dichroism of the material has also been explored.
