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.

Fucoidan - Ascophyllum nodosum, analytical grade
CAS :A fucan sulphate found in brown marine algae (Phaeophyta-typically Fucus vesiculotus, Ascophyllum nodosum (illustrated), Alaria and Cladosiphon) and has been shown to have anticoagulant activity. The main constituents are α-1,4 and α-1,2 linked L-fucose sulphates although galactose also occurs and there are many variations of the basic structure found in different species of Phaeophyta.Molecular weight cut off at 300kDa.The image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.Couleur et forme :PowderCarboxymethyl curdlan
CAS :Carboxymethyl curdlan is widely used in the preparation of nanoparticles for biomedical applications. Following the synthesis of superparamagnetic iron oxide nanoparticles (SPIN) capped with carboxymethyl curdlan for use in cellular and in vivo imaging applications, the stability and dispersibility of SPIN in water were greatly improved with the introduction of the carboxymethyl curdlan moiety. Recently, a green and simple route was proposed to synthesize Ag nanoparticles using carboxymethylcurdlan under UV irradiation.Couleur et forme :PowderWheat starch
CAS :Starch is an energy storing polysaccharide produced by higher plants and some algae. Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. It consists of two types of polysaccharide: the linear and helical amylose (α-1,4-linked glucose) and the branched amylopectin (α-1,4 and α-1,6-linked glucose). Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight.Degré de pureté :Min. 95%Couleur et forme :PowderHydroxypropyl Cellulose (3-6mPa·s, 2% in Water at 20°C)

Compression wood is a type of reaction wood formed on the underside of softwood stems when they are tilted from the vertical and on the underside of branches, which unlike normal wood contains significant amounts of β-(1,4)-galactan.Degré de pureté :Min. 95%Couleur et forme :Off-White To Brown SolidEthyl Cellulose [18-22mPa·s, 5% in Toluene + Ethanol (80:20) at 25°C]

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 colitis, due to its simplicity and similarities to human inflammatory bowel disease.Couleur et forme :PowderChitin
CAS :Formule :C8H13NO5nCouleur et forme :White to tan, orange or pink powderMasse moléculaire :[203.19]nAmidated Pectin
CAS :Pectins are derived from citrus fruits such as lemons and limes. Amidated pectin is a modified form of pectin in which some of the galacturonic acid residues are converted with ammonia to amides. These pectins are more tolerant to varying calcium concentrations that occur in use and behave like low-ester pectins, need less of and are more tolerant to excess calcium. In addition, these gels are thermoreversible.Formule :C5H10O5Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :150.13 g/mol
