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.

Bacterial alginate - from fermentation of Azotobacter vinelandii or Pseudomonas mendocina
An alginate-like polysaccharide produced by the fermentation of Azotobacter vinelandii or Pseudomonas mendocina. The chemical structure consists of blocks of (1,4) linked-β-D-polymannuronic acid (poly M), (1,4) linked-α-L-polyguluronic acid (poly G) and alternating blocks of the two uronic acids (poly MG). Unlike the alginate from seaweed, this polysaccharide is partially acetylated.Couleur et forme :PowderMasse moléculaire :~100KDaRhamnogalacturonan - from Okra
CAS :Rhamnogalacturonan is a natural polysaccharide that is a major component of plant cell walls. It can be synthesized in the laboratory and modified with different functional groups to alter its properties. Rhamnogalacturonan has been shown to have anti-inflammatory, antioxidant, and immunomodulatory activities. It also has the ability to inhibit bacterial growth and stimulate phagocytosis by macrophages. This product has a high purity, is custom synthesized, and can be modified with different functional groups.Degré de pureté :Min. 95%Levan
CAS :Formule :(C6H10O5)nDegré de pureté :≥ 95%Couleur et forme :White to off-white or faint yellow powderPolyguluronic acid
CAS :Polyguluronic acid is produced from alginates by partial hydrolysis and chromatography of brown algae such as Laminaria digitata, Ascophyllum nodosum and Fucus spp. The image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.MW is less then 8000Da.Degré de pureté :(%) Min. 80%Couleur et forme :Off-White PowderMasse moléculaire :194.14Gellan gum
CAS :Gellan is a microbial polysaccharide produced by Pseudomonas elodea and generates gels with similar properties to agar. Gellan gum is a linear tetrasaccharide of (1,4)-β-L-rhamnopyranosyl, (1,3)-α-D-glucopyranosyl, (1,4)-β-D-glucuronopyranosyl, (1,4)-β-D-glucopyranosyl- with O(2) L-glyceryl and O(6) acetyl substituents on the 3-linked glucose. Both substituents are located on the same glucose residue, and on average, there is one glycerate per repeat and one acetate per every two repeats. In low acyl gellan gum, the acyl groups are removed completely. The high acyl form produces soft, elastic, non-brittle gels, whereas the low acyl form produces firm, non-elastic, brittle gels.Degré de pureté :(Carbon Dioxide) 3.3 To 6.8%Couleur et forme :White Off-White PowderChitosan - Molecular weight 190,000-310,000
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.Couleur et forme :Off-White PowderChitosan - Molecular weight 310,000-375,000

CAS :Pectin is a highly complex polysaccharide matrix that is found in the primary walls of dicotyledenous and monocotyledenous plants and gymnosperms, including soy plants. A key fragment of this complex is rhamnogalacturonan I, containing a backbone of the repeating disaccharide [-4)-α-D-GalpA-(1,2)-α-L-Rhap-(1,]. Several applications for RG1 have been described including drug targeting to the colon via the oral administration route for local treatment of e.g. inflammatory bowel disease and colonic cancer. This has several advantages such as needle-free administration and low infection risk and in the gastro-intestinal tract RG-I is only degraded by the action of the colonic microflora. High purity rhamnogalacturonan I is also used in research, biochemical enzyme assays and in vitro diagnostic analysis.Degré de pureté :Min. 95%Couleur et forme :SolidCarboxymethyl chitosan (10 - 80 cps), fungal origin
