| titleOfInvention | Unsaturated hyaluronic acid tetrasaccharide |
| abstract | The invention relates to unsaturated hyaluronic acid tetrasaccharide and a preparation method thereofIt is an ionic compound and the general formula of the anion structure is shown as the formula (1): wherein X is hydrogen or methyl. The 4 and 5 positions of the non-glucuronic acid are set to be unsaturated double bonds, so that the hyaluronic acid has strong water absorption property as common hyaluronic acid and also has stronger oxidation resistance. |
