Heparin sodium salt
CAS:<p>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>Cor e Forma:White PowderGhatti gum
CAS:<p>Gum ghatti is an exudate gum from the tree Anogeissus latifolia found in India and Sri Lanka. Applications are similar to Gum arabic in the food and pharmaceutical industries, where it is used as an emulsifier. The polysaccharide is reported to have an extremely complex structure which contains both oligosaccharides and polysaccharide elements. The polysaccharide contains Ara, Gal, Man, GlcA and Rha in a molar ratio of 61:39:6:10:6, a backbone of (1,6)-linked β-D-galactopyranosyl units and side chains of L-arabinofuranose units with some (1,4)-D-glucopyranosyluronic acid units, some joining (1,2)-D-mannopyranosyl units.</p>Cor e Forma:Off-White PowderHydroxypropyl cellulose - Average MW 370,000
CAS:<p>In water, hydroxypropyl cellulose forms liquid crystals with many mesophases depending on concentration. These mesophases include isotropic, anisotropic, nematic and cholesteric, the latter resulting in many colors such as violet, green and red. Pharmaceutical applications include treatments for medical conditions such as dry eye syndrome (keratoconjunctivitis sicca), recurrent corneal erosions, decreased corneal sensitivity, exposure and neuroparalytic keratitis. It is also used as a binder in tablets. Hydroxypropylcellulose is also used as a thickener, a binder and emulsion stabiliser in foods with E number E463. HPC is used as a support matrix for DNA separations by capillary and microchip electrophoresis.</p>Pureza:Min. 95%Cor e Forma:PowderCurdlan
CAS:<p>Curdlan is a microbial polysaccharide produced by a mutant strain of Alcaligenes faecalis var. myxogenes which was first shown to produce succinoglucan prior to mutation. Curdlan is a β-1,3 glucan forming clear solutions at about 55 °C which then gels (“low-set”) when cooled. Suspensions of curdlan at higher temperatures form firm resilient gels (“high set”) that melt at 140 - 160 °C.<br>The image was kindly provided by Dr. Chris Lawson.</p>Pureza:Min. 95%Cor e Forma:White PowderKephir gum
CAS:<p>‘Water kefir’ is a home-made beverage, which was thought to contain significant amounts of bacterial exopolysaccharides.

In addition, it was shown that a small amount of levan is also present.</p>Pureza:Min. 95%Cor e Forma:PowderPectic acid
CAS:<p>Pectic acid is non water-soluble β (1,4)-linked polygalacturonic acid. In its gel form, is water-soluble, transparent and gelatinous, and exists in ripe fruit and some vegetables. It is a product of pectin degradation in plants, and is produced via the interaction between pectinase and pectin (the latter being common in the wine-making industry).</p>Pureza:Min. 95%Cor e Forma:PowderDextran sulfate sodium, MW 20,000
CAS:<p>Sodium carboxymethyl dextran (CM-dextran) is a white, odourless and tasteless powder, which is freely soluble in water or electrolyte solutions. The product has a pronounced polyanionic character, due to the high degree of carboxyl substitution. Applications that have been described for CM-dextran include carriers of paramagnetic contrast agents, preparation of conjugates of pharmacologically active compounds and CM-dextrans in biosensors. A number of other uses in cosmetics, agriculture, foods, paints and textiles have been the subject of patent applications.</p>Cor e Forma:PowderFucoidan, fucus vesiculosus
CAS:<p>A fucan sulphate found in brown marine algae (Phaeophyta-typically fucus vesiculosus (illustrated), Ascophyllum nodosum, Alaria 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.<br>The fucose content of this fucan is approx. 43.1% and it also contains galactose (approx. 8.8%), uronic acid (approx. 8.7%) and sulfate (approx. 30.6%).<br>The image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.</p>Pureza:Min. 95%Cor e Forma:White PowderDe-N-sulfated heparin sodium
