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.

kappa-Carrageenan
CAS :Kappa-Carrageenan is a gelling sulphated galactan extracted from red seaweed (typically Mastocarpus stellata and Chondrus crispus). The structure of all carrageenans consists of a strictly alternating masked repeating unit of 1,3-linked α-D-galactose and 1,4-linked β-D-galactose. The α-linked galactose occurs as α-3-6-anhydro unit and the β-linked sugar occurs as the 4-sulphate.

CAS :Danaparoid sodium (the active pharmaceutical ingredient in Orgaran; Merck Sharp and Dohme) is a biopolymeric non-heparin drug that is used as anticoagulant and antithrombotic agent, approved for the prophylaxis of postoperative deep-vein thrombosis. It consists of a mixture of three glycosaminoglycans: heparan sulphate, dermatan sulphate, and chondroitin sulphate. Danaparoid, has well established antithrombotic activity. The drug has a high antifactor Xa to antifactor IIa (thrombin) activity ratio, a low tendency to cause bleeding and minimal effects on the fibrinolytic system.
Degré de pureté :Min. 95%Couleur et forme :White PowderCellulose - Microcystalline USP
CAS :Cellulose is a linear polysaccharide of β 1-4 linked glucose residues. The polysaccharide chains are bundled as microfibrils in cell walls and provide the essential structural components within growing plants. Each microfibril exhibits a high degree of three-dimensional internal bonding resulting in a crystalline structure that is insoluble in water, resistant to reagents and very strong. The crystalline region of cellulose is isolated to produce microcrystalline cellulose. Microcrystalline cellulose is a term for refined wood pulp and is used as a texturizer, an anti-caking agent, a fat substitute, an emulsifier, an extender, and a bulking agent in food production.
Degré de pureté :Min. 95%Welan gum
CAS :Welan gum is a microbial polysaccharide produced by a species of Alcaligenes and shows interesting rheological properties of use in the oil and agricultural industries. The structure is similar to gellan based on repeating glucose, rhamnose and glucuronic acid units but with a single side chain of either an α-L-rhamnopyranosyl or an α-L-mannopyranosyl unit linked (1,3) to the 4-O-substituted β-D-glucopyranosyl unit in the backbone.Degré de pureté :Viscosity >1700 CpCouleur et forme :PowderN-Trimethylchitosan
CAS :Quaternization of the primary amine in N-Trimethylchitosan increases the water solubility of chitosan and keeps chitosan soluble over a wide pH range. N-Trimethylchitosan is soluble in water and ethanol, making it ideal for use in biotechnology applications.The degree of quaternization is 30-70%Degré de pureté :Min. 90%Cellulose acetate - MW 30,000
CAS :Cellulose acetate fiber is one of the earliest synthetic fibers and is based on cotton or tree pulp cellulose. Cellulose acetate is used as a film base in photography, as a component in some coatings, and as a frame material for eyeglasses. It is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards. In photographic film, cellulose acetate replaced nitrate film in the 1950s, being far less flammable and cheaper to produce but in recent years has been rendered obsolete by the advent of digital cameras.Couleur et forme :Powderβ-1,3-Glucan
CAS :β-1,3-Glucan is a bioactive polysaccharide, which is located predominantly in the cell walls of yeast, fungi, and certain cereals. This compound is characterized by its unique branched structure, which is crucial for its biological function. The mode of action of β-1,3-Glucan involves the binding to specific receptors on immune cells, such as dectin-1, which triggers a cascade of immune responses. This interaction enhances the activity of macrophages, neutrophils, and natural killer cells, thus bolstering the body's innate immune defenses.The uses and applications of β-1,3-Glucan are broad, primarily focused on immunological research and potential therapeutic strategies. It is extensively utilized in studies examining its effects as an immunomodulator, leveraging its ability to potentiate immune system function and examining its role in adjunctive cancer therapies, where it may enhance the efficacy of certain treatments. Additionally, β-1,3-Glucan is investigated for its potential benefits in reducing infection rates and improving recovery times in clinical settings. Moreover, its applications in dietary supplements and functional foods continue to be a subject of scientific inquiry, aiming to harness its health-promoting properties within nutrition science.Degré de pureté :Min. 95%Couleur et forme :Powder(Hydroxypropyl)methyl cellulose, viscosity 5 cP 80%-120%, 2% aqueous solution

CAS :Poria cocos is an edible medicinal fungus known as “Fuling” in Chinese that has been used as a Chinese traditional medicine for more than two thousand years. Polysaccharide material is the most abundant organic substance in the fungus, accounting for about 85% of the total and is a mixture of polysaccharides with the major component being Pachyman, a β-glucan with a 1,3 backbone and 1,6 side chains. It is reported that Pachyman has a wide range of biological activities including antitumour, immunomodulatory, anti-inflammatory and antioxidative properties. Pachyman is a beta-glucan with a 1,3 backbone and 1,6 side chains of fungal origin (Poria cocos).

CAS :Chondroitin sulfate A sodium from bovine trachea is a natural substance that has been found to have potential anticancer properties. It has been shown to inhibit the growth of cancer cells in Chinese hamster ovary cells and human urine tumor cell lines. Chondroitin sulfate A sodium from bovine trachea works by inhibiting kinases, which are proteins that play a key role in cell growth and division. This inhibition leads to apoptosis, or programmed cell death, in cancer cells. Additionally, chondroitin sulfate A sodium from bovine trachea has been found to enhance the anticancer activity of artesunate analogs, making it a promising candidate for combination therapy in cancer treatment.Degré de pureté :Min. 95%Couleur et forme :PowderLaminariheptaose
