Unsaturated hyaluronate tetrasaccharide and preparation method thereof
-
Paragraph 0040; 0041; 0046-0048, (2019/10/01)
The invention relates to unsaturated hyaluronate tetrasaccharide and a preparation method of unsaturated hyaluronate tetrasaccharide. Unsaturated hyaluronate tetrasaccharide is an ionic compound; a negative ion structure general formula of unsaturated hyaluronate tetrasaccharide is shown as formula (1) as shown in the specification; and X is hydrogen or methyl. Sites 4 and 5 of terminal glucuronicacid are set as unsaturated double bonds, so that unsaturated hyaluronate tetrasaccharide has as strong water absorptivity as common hyaluronic acid and stronger oxidation resistance.
