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.

Exopolysaccharide - from Flavobacterium
Bacterial exopolysaccharide from gram negative Flavobacterium spp.Degré de pureté :Min. 95%Couleur et forme :White To Yellow Or Brown SolidHyaluronic acid sodium salt - Low molecular weight 10,000 - 50,000
CAS :Gycosaminoglycan in many organs; joint lubricant and shock absorberFormule :(C14H20NO11Na)nDegré de pureté :Min. 95.0%Couleur et forme :PowderGlucurono-xylomannan polysaccharide from Tremella fuciformis
CAS :The polysaccharide, known as glucuronoxylomannan - produced by fruit bodies and in pure culture conditions - has been shown to consist of a mannan backbone that is glycosylated with xylan and glucuronic acid chains in a regular repeating structure. Laboratory tests have associated a number of biological activities with Cryptococcus neoformans glucuronoxylomannan, including immunostimulatory, antidiabetic, anti-inflammatory, hypocholesterolemic, hepatoprotective, and antiallergic effects. The image was kindly provided by Dr. Chris Lawson.Degré de pureté :(%) Min. 60%Couleur et forme :White Off-White PowderRhodamine B isothiocyanate-dextran - Average MW 70,000
The fluorescence intensity of these Rhodamine B isothiocyanate-dextrans varies much less than with FITC-dextrans.Couleur et forme :PowderMasse moléculaire :7,000 g/molFucoidan, cladosiphon
CAS :A fucan sulphate found in brown marine algae (Phaeophyta-typically Fucus vesiculotus, Ascophyllum nodosum, Alaria and Cladosiphon (illustrated) 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. The fucose content of the fucan is approx. 51% and it also contains galactose (approx. 6.3%), uronic acid (approx. 15.5%) and sulfate (approx. 25%). The image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.Degré de pureté :Min. 95%Couleur et forme :White Powder(+)-Arabinogalactan from Larch Wood,
CAS :Formule :C20H36O14Degré de pureté :95%Couleur et forme :SolidMasse moléculaire :500.4914Cellotriose
CAS :Formule :C18H32O16Degré de pureté :>95.0%(HPLC)Couleur et forme :White to Almost white powder to crystalMasse moléculaire :504.44Amylopectin - from potato starch
CAS :Starch component; highly branched glucanCouleur et forme :White Off-White PowderHydroxyethyl cellulose, viscosity 1500 ~ 2500
CAS :Hydroxyethyl cellulose (EHEC) is a non-ionic, water-soluble cellulose derivative produced by introduction of ethylene oxide groups to the hydroxyl groups of the cellulose backbone. Hydroxyethyl cellulose is useful as a water thickener, rheological control additive, protective colloid, binder, stabilizer, suspending agent and film former. It is used in many industrial applications including latex paints, emulsion polymerization, petroleum, paper, pharmaceuticals, cosmetics and many other applications.Degré de pureté :Min. 95%Couleur et forme :PowderLaminaran, from laminaria digitata
CAS :Laminaran is a polysaccharide that co-occurs with fucoidan and alginate in brown seaweeds such as Laminaria digitata, Laminaria cloustoni, Eisenia bicyclis and Thallus laminariae. It is a β-1,3-linked glucan which it is claimed stimulates the immune system in mammals and fish. The image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.Degré de pureté :Min. 95%Couleur et forme :Off-White PowderChondroitin sulfate A sodium salt - Average MW 10,000 - 30,000
CAS :The disaccharide repeating unit of chondroitin sulphate consists of N-acetyl galactosamine sulphate linked β1,4 to glucuronic acid. Each monosaccharide may be left unsulphated, sulphated once, or sulphated twice. The most common pattern has the hydroxyl groups of the 4 and 6 positions of the N-acetyl-galactosamine sulphated, with some chains having the position 2 of the glucuronic acid sulphated.Degré de pureté :Min. 90%Couleur et forme :White Off-White PowderLaminaran - from Laminaria cloustoni
CAS :Laminaran is a polysaccharide that co-occurs with fucoidan and alginate in brown seaweeds such as Laminaria digitata, Laminaria cloustoni, Eisenia bicyclis and Thallus laminariae.
