Kappa-Carratriose Disodium Salt

1.origin: red alga

2.preparation: monomers of carrageenan oligosaccharide are made from carrageenan, and obtained by enzymatic hydrolysis, chemical derivatization and column chromatography, including kappa-carratriose disodium salts and iota-carratriose disodium salts.

3.character: they are light yellow power or flocculent lyophilized things, with odor free and humidifying.

4.toxicity: non-toxic

5.shelf life: ≥ 3 years under frozen state

6.inspection: tlc, hpgpc, esi-ms

7.application: carrageenan oligosaccharide standards can be developing carrageenan oligosaccharide’s applications in pharmaceuticals, foods, modern agriculture, feed, daily chemical industry and biochemical reagents. they are reference substances in assay, analysis and quality control. they could also be applied in research fields of carbohydrate chemistry and glycobiology, such as preparation of oligosaccharide microarray, the interaction between oligosaccharide and protein, and structure-activity relationship and mechanism of oligosaccharide-derived medicine.
