Polysaccharides
Les polysaccharides sont des composés organiques formés par l'union de plusieurs monomères, liés entre eux par des liaisons glycosidiques pour créer de grandes molécules souvent ramifiées. Ces glucides complexes jouent des rôles cruciaux dans diverses fonctions biologiques, y compris le stockage d'énergie, le soutien structurel et la communication cellulaire. Dans cette section, vous trouverez une gamme variée de polysaccharides essentiels pour la recherche en biochimie, biologie moléculaire et glycosciences. Ces composés sont vitaux pour l'étude des voies métaboliques, des structures de la paroi cellulaire et du potentiel thérapeutique des glucides. Chez CymitQuimica, nous proposons des polysaccharides de haute qualité pour soutenir vos recherches scientifiques, garantissant précision et fiabilité dans vos résultats expérimentaux.

Dextran sulfate sodium salt - MW 4500-5500
CAS :Dextran sulphate is a dextran derivative whose ulcer (colitis) -causing properties were first reported in hamsters and extrapolated a few years later to mice and rats. The exact mechanisms through which dextran sulphate induces intestinal inflammation are unclear but may be the result of direct damage of the monolayer of epithelial cells in the colon, leading to the crossing of intestinal contents (for e.g. commensal bacteria and their products) into underlying tissue and therefore induction of inflammation. The dextran sulphate sodium induced ulceration model in laboratory animals has some advantages when compared to other animal models of colitisdue to its simplicity and similarities to human inflammatory bowel disease.Degré de pureté :Min. 95%Couleur et forme :Powderκ-Carrageenan
CAS :Kappa-Carrageenan is a gelling sulphated galactan extracted from red seaweed (typically Mastocarpus stellata and Chondrus crispus). The structure of all carrageenans consists of a strictly alternating masked repeating unit of 1,3-linked α-D-galactose and 1,4-linked β-D-galactose. The α-linked galactose occurs as α-3-6-anhydro unit and the β-linked sugar occurs as the 4-sulphate.

CAS :Guar gum is obtained from the seed of the legume Cyamopsis tetragonolobus, an annual plant that grows mainly in semi-arid regions of India. The structure of the polysaccharide consists of a main chain of (1,4)-linked β-D-mannopyranosyl units with single α-D-galactopyranosyl units linked (1,6) on average to every second main chain unit. Guar has a high viscosity in aqueous solution, shows marked pseudoplastic behaviour and forms synergistic gels in the presence of other gums such as carrageenan and xanthan gum.Formule :C10H14N5Na2O12P3Couleur et forme :White PowderMasse moléculaire :535.15 g/molPustulan
CAS :Pustulan is a β-1,6-glucan isolated from Lasallia pustulata MW (20 kDa). It is recognized by the membrane bound Dectin-1, a C-type lectin-like pattern recognition receptor. Detection of β-glucans by Dectin-1 receptor leads to the CARD9-dependent activation of NF-κB and MAP kinases. Studies have shown that pustulan can stimulate innate immune responses, inducing heat shock protein expression, eliciting phagocytosis, and production of pro-inflammatory cytokines.

CAS :Chondroitin sulfate A sodium from bovine trachea is a natural substance that has been found to have potential anticancer properties. It has been shown to inhibit the growth of cancer cells in Chinese hamster ovary cells and human urine tumor cell lines. Chondroitin sulfate A sodium from bovine trachea works by inhibiting kinases, which are proteins that play a key role in cell growth and division. This inhibition leads to apoptosis, or programmed cell death, in cancer cells. Additionally, chondroitin sulfate A sodium from bovine trachea has been found to enhance the anticancer activity of artesunate analogs, making it a promising candidate for combination therapy in cancer treatment.Degré de pureté :Min. 95%Couleur et forme :PowderHyaluronic sodium - Average MW 0.2-0.5 million Daltons
CAS :The sodium salt of hyaluronic acid is a glycosaminoglycan found in many organs, where it functions as a joint lubricant and shock absorber. It is obtained principally from synovial fluid, vitreous humor of the eye, umbilical tissue and cocks comb. The chemical structure of hyaluronic is a disaccharide repeat of β-(1,3) glucuronic acid and β-(1,4) N-acetyl glucosamine.Formule :(C14H20NO11Na)nDegré de pureté :Min. 95%Couleur et forme :PowderHyaluronic acid sodium salt - Low molecular weight 80,000 - 100,000

CAS :Chitosan is the deacetylated form of chitin. The polysaccharide is deacetylated in order to render it soluble, which is then possible at pH values of less than 7 (normally in dilute acid). This then allows the material to be used in a number of industrial applications as a binder and film former.MW typically 10-100kDa.Couleur et forme :Off-White PowderLichenan - from Cetraria islandica
CAS :Lichenin, the poly β-D-Glucan of Cetraria islandica (Iceland moss), is found by enzymic degradation to differ in fine structure from the poly β-D-glucans of cereal grains. Thus, the basic structure of lichenin is a tetrameric unit in which two adjacent 1,4 linkages alternate with an isolated 1,3 linkage; occasionally four consecutive monomers are linked by 1,4 bonds. The immunomodulatory activity of isolichenan was tested in in vitro phagocytosis and anti-complementary assays, and proved to be active in both cases.
