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.

Methyl cellulose - USP (viscosity ca 1500cP)
CAS :<p>Cellulose derivative, food thickener and emulsifier, bulk forming laxative</p>Couleur et forme :PowderPeptidoglycan - from Staphylococcus aureus
CAS :<p>The sugar component consists of alternating residues of β-(1,4) linked N-acetylglucosamine and N-acetylmuramic acid. A peptide chain of three to five amino acids is attached to the N-acetylmuramic acid. The peptide chain can be cross-linked to the peptide chain of another strand forming the 3D mesh-like layer.</p>Couleur et forme :PowderChondroitin sulfate A sodium salt - Average MW 20,000 - 30,000
CAS :<p>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 is that the hydroxyl groups of the 4 and 6 positions of the N-acetyl-galactosamine are sulphated, with some chains having the position 2 of the glucuronic acid sulphated.</p>Degré de pureté :Min. 90 Area-%Couleur et forme :White PowderN-Acetyl-de-O-sulfated heparin sodium salt
CAS :<p>N-Acetyl-de-O-sulphated heparin is a glycosaminoglycan, which occurs in many mammalian tissues and has important anticoagulant and thrombolytic properties. The chemical structure is composed mainly of two disaccharide repeating units A and B. A is L-iduronic acid 2-suplhate linked α-(1,4) to 2-deoxy-2-sulfamido-D-galactose 6-sulphate, while B is D-glucuronic acid β-(1,4) linked to 2-deoxy-2-sulfamido-D-glucose 6-sulphate.</p>Degré de pureté :Min. 95%Couleur et forme :PowderHyaluronic acid sodium salt - Average MW 1.0 - 2.0 million Da
CAS :<p>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.</p>Formule :(C14H20NO11Na)nCouleur et forme :PowderUlvan
CAS :<p>Ulvans are structural polysaccharides present in the cell walls of green algae such as Ulva armoricana, Ulva rotondata, Ulva rigida, Ulva lacterca and Ulva pertusa. They are highly sulphated and contain rhamnose 3-sulphate, xylose, xylose 2-sulphate, glucuronic acid and iduronic acid residues. Ulvan has several potentially valuable functionalities such as gel formation for agricultural and food applications and possible anticoagulant, antioxidant, antihyperlipidemic and antitumor activities for pharmaceutical applications.<br>The image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.</p>Couleur et forme :PowderHyaluronic acid sodium salt - Low molecular weight 10,000 - 50,000

CAS :<p>Chondroitin sulphate is the most abundant glycosaminoglycan in mammalian tissues and occurs both in skeletal and soft connective tissue. The disaccharide repeat unit consists of N-acetyl galactosamine sulphate linked β1,4 to glucuronic acid.</p>Degré de pureté :Min. 95%Couleur et forme :White Off-White PowderLevan - from Erwinia herbicola
CAS :<p>Levan is a (2,6)-linked fructan produced by Erwinia herbicola. The polysaccharide contains branches every 10-12 fructose residues linked (1,2) and is reported to have a molecular weight in excess of 1000 KDa. Potential industrial applications of levan have been proposed as an emulsifier, formulation aid, stabilizer and thickener, surface-finishing agent, encapsulating agent, and carrier for flavor and fragrances. In addition, levan is promising in medicine as a plasma substitute, drug activity prolongator and antihyperlipidemic agent.</p>Degré de pureté :Min. 95%Couleur et forme :PowderColloidal Chitin
CAS :<p>Chitin is a polysaccharide which is found widely in nature, where it functions in a manner similar to collagen in chordates. It forms the tough fibrous exoskeletons of insects, crustaceans and other arthropods, and, in addition to its presence in some fungi, it occurs in at least one alga. The structure of chitin is similar to that of cellulose but with glucose replaced with N-acetyl-D-glucosaminyl units linked β-D-(1,4) in a linear chain. It is normally produced from the shells of lobster, crab or shrimp.</p>Couleur et forme :PowderHyaluronic acid sodium salt - Average MW 1.5 - 2.5 million Da
CAS :<p>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.</p>Formule :(C14H20NO11Na)nDegré de pureté :Min. 95%Couleur et forme :PowderPsyllium seed gum
CAS :<p>Psyllium seed gum comes from plants of the Plantago genus and is cultivated mainly in the Mediterranian and in India. Psyllium has been used for many years medical applications and more recently there has been a resurgency of interest because it has been seen as a soluble dietary fibre. The proposed structure is of a backbone of D-xylopyranosyl units linked (1,4) and (1,3) with the 4-linked units bearing side chains. The side chains consist of α-L-arabinofuranosyl units linked (1,3) and (1,2) and β-D-xylopyranosyl units linked (1,3) and (1,2) and the α-D-GalAρ-(1,2)-α-L-Rhaρ aldobiuronic acid units linked (1,2) to the main chain.</p>Formule :C33H66O2Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :494.90 g/molDextran sulfate sodium salt - MW 9,000-11,000 - from Leuconostoc spp
CAS :<p>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.</p>Degré de pureté :Min. 95%Couleur et forme :PowderHyaluronic acid sodium salt - Average MW 70,000-80,000
CAS :<p>Gycosaminoglycan in many organs; joint lubricant and shock absorber</p>Formule :(C14H20NO11Na)nDegré de pureté :Min. 90 Area-%Couleur et forme :PowderCarboxymethyl chitosan
CAS :<p>Carboxymethyl chitosan has good solubility in water and unique chemical, physical and biological properties such as high viscosity, large hydrodynamic volume, low toxicity, biocompatibility and good ability to form films, fibres and hydrogels. For this reason, it has been extensively used in many biomedical fields such as a moisture-retention agent, bactericide, wound dressing agent, in artificial bone and skin, as blood anticoagulant and as a component in different drug delivery matrices. The reactive ligands COOH and NH2 groups are available for metal chelation and dye binding.</p>Couleur et forme :White PowderN-Acetyl-heparin
