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.

Arabinan
CAS :Sugar beet arabinan consists of a 1,5 α-linked arabinose backbone to which 1,3 α-linked (and possibly some 1,2 α-linked) L-arabinofuranosyl residues are attached. Approximately 60% of the main-chain arabinofuranosyl residues are substituted by single 1,3-linked arabinofuranosyl groups. The reducing terminal arabinosyl residue is attached through rhamnose to fragments of the rhamnogalacturonan backbone of the native pectin molecule.Couleur et forme :White PowderLevan - from Erwinia herbicola
CAS :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.Degré de pureté :Min. 95%Couleur et forme :Powderβ-D-Glucan, 70%, from Oat

CAS :A fucan sulphate found in brown marine algae (Phaeophyta-typically Fucus serratus, Ascophyllum nodosum (illustrated), Laminaria japonica and Macrocystis pyrifyra) 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 image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.Degré de pureté :Min. 95%Couleur et forme :White PowderLM Pectin
CAS :Pectins are regarded as linear chains of α-1,4-linked D-galacturonic acid, a homogalacturonan (pectic acid). In the products of commerce, the degree of methylation has a vital influence on the properties of pectin, especially the solubility and gel forming characteristics.Couleur et forme :PowderAzo-Xyloglucan
Dyed and soluble azo-xyloglucan (tamarind) is used for the measurement of enzyme activity, research, biochemical enzyme assays and in vitro diagnostic analysis. It is a soluble chromogenic substrate for the assaying of endo-cellulase.Degré de pureté :Min. 95%Colloidal Chitin
CAS :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.Couleur et forme :PowderCarboxymethyl chitosan (10 - 80 cps), suitable for microbiology
CAS :Couleur et forme :White to light yellow or pale beige powderFluorescein isothiocyanate-dextran - Average MW 3,000-5,000
CAS :Fluorescein isothiocyanate dextran is a fluorescent derivative of a dextran fraction with an average molecular weight of approximately 4000. It is supplied as a yellow powder which is readily soluble in water.Degré de pureté :Min. 95%Dextran sulfate sodium salt - MW 9,000-11,000 - from Leuconostoc spp
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.Degré de pureté :Min. 95%Couleur et forme :PowderDextran sulfate sodium, MW 100,000

CAS :Tamarind gum comes from the seed of the tamarind tree Tamarindus indica and is used in the food industry as a stabiliser and an emulsifier. It has been suggested that the structure is a main chain of cellulose with frequent branching at the O-6 positions with short side chains of one or two D-xylopyranosyl capped with D-xylopyranosyl, D-galactopyranosyl or L-arabinofuranosyl units. In application, tamarind finds use in the sizing of jute and as a stabilizer and thickener in the food industry.Couleur et forme :PowderHyaluronic acid sodium salt, m.w. 1.0MDa, Ph. Eur. grade, low endotoxin
CAS :Formule :(C14H20NNaO11)nDegré de pureté :95.0 - 105.0 % (dried basis)Couleur et forme :White to almost white powder, hygroscopicHM Pectin
CAS :Pectins are regarded as linear chains of α-1,4-linked D-galacturonic acid, a homogalacturonan (pectic acid). In the products of commerce, the degree of methylation has a vital influence on the properties of pectin, especially the solubility and gel forming characteristics. Commercial high methoxy (HM) pectin has > 70% of hydroxyl groups methyl esterified. HM pectin forms gels in the presence of sucrose and for this reason it is used in jams often in combination with other fruits.Degré de pureté :(%) Min. 85%Couleur et forme :PowderFluorescein isothiocyanate-dextran - Average MW 20,000
