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.

CAS :Colominic acid (polysialic acid) is a linear small polysaccharide containing α-2,8-linked sialic acid (neurominic acid) with (n = 8 to >100) residues. Polysialic acid is an unusual post translational modification polysaccharide that is widely expressed in nature in bacterial capsules, fish, sea urchin eggs, embryonic tissues, amphibians, animal and human brains, and in a various cancers. The major carrier of polysialic acids in mammals is the neural cell adhesion molecule (a glycoprotein that belongs to the immunoglobulin superfamily).Average molecular weight for this product is :50000-60000Degré de pureté :Min. 98 Area-%Couleur et forme :White Off-White PowderAgar, high gel strength

CAS :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.Couleur et forme :White PowderGellan Gum, high acyl

CAS :Formule :C6H7O2(OH)x(OCH2COONa)ynCouleur et forme :White to Light yellow to Light orange powder to crystalFluorescein isothiocyanate-dextran - Average MW 10,000
CAS :Fluorescein dextran (FD) is widely used as both an anterograde and retrograde tracer in neurons and for numerous other applications. It is biologically rather inert having α-1,6-linked glucose residues resistant to cleavage by most endogenous cellular glycosidases. It has low immunogenicity and makes an ideal long-term tracer for live cells. FD also serves as a valuable marker for cell loading of macromolecules by micro-injection, vesicular fusion, and electroporation, as well as for the uptake and internal processing of exogenous materials by phagocytotic and endocytic pathways.Degré de pureté :Min. 95%Pullulan
CAS :Pullulan is a glucan elaborated by the fungus Aureobasidium pullulans. The chemical structure is essentially repeating units of maltotriose joined by α-1,6 linkages. Pullulan dissolves readily in water to form stable, viscous solutions that do not gel. The polysaccharide can be moulded, made into fibres and forms clear soluble films. Applications are in foods as a low calorie ingredient and the polysaccharide forms water soluble films that have been used as seed coatings and to coat fruit. Pullulan can also be used in industrial applications as a binder, film former and in pharmaceutical applications. Average MW is typically 100-200kDa. Viscosity is ca 120 mm2/s.

CAS :A fucan sulphate found in brown marine algae (Phaeophyta-typically Fucus vesiculotus, Durvillea (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. The fucose content of this fucan is approximately 27.9% and it also contains galactose (approx. 6.2%), uronic acid (approx. 22.4%) and sulfate (approx. 21.4%).

CAS :A fucan sulphate found in brown marine algae (Phaeophyta-typically Fucus vesiculotus, Ecklonia (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. The fucose content of this fucan is approx. 19.0% and it also contains galactose (approx. 12.0%), uronic acid (approx. 25.5%) and sulfate (approx. 19.1%).

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 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.Degré de pureté :Min. 90 Area-%Couleur et forme :White Powder(Hydroxypropyl)methyl cellulose phthalate
CAS :Hypromellose phthalate (hydroxypropyl methylcellulose phthalate, or HPMCP) is a phthalic acid ester of hydroxypropyl methylcellulose. Hypromellose phthalate was introduced in 1971 as a cellulose derivative for enteric coatings, used to protect drugs from degradation by gastric acid or to prevent them from causing side effects in the stomach. HPMCP is also used in sustained-release preparations, in binders and as microcapsule bases.Couleur et forme :White Off-White Powder
