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.Pureza:Viscosity >1700 CpCor e Forma:PowderCellulose 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.Cor e Forma:PowderPachyman - from Poria cocos
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: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.

CAS:Viscoelastic polymer; excipient; food additiveDiethylaminoethyl-dextran
CAS:DEAE-Dextran (DEAE-D) is a positively-charged dextran derivative that can be used for vaccine production, gene therapy, protein stabilisation, dyslipidemia prevention, flocculating agents, and many other applications. DEAE-D is also used for transfecting animal cells with foreign DNA. DEAE-Sepharose, DEAE-650 and DEAE-Sephadex are commonly used in chromatography for the separation of biological molecules such as proteins and carbohydrates.Pureza:Min. 95%Porphyran
CAS:Porphyran is an agar-like polysaccharide with a linear backbone consisting of 3 linked β-D-galactosyl units alternating with either 4-linked α-L-galactosyl 6-sulphate or 3-6-anhydro-α-L-galactosyl units.The composition includes 6-O-sulphated L-galactose, 6-O-methylated D-galactose, L-galactose, 3,6-anhydro-L-galactose, 6-O-methyl D-galactose and ester sulphate. Some of the ester is present as 1,4-linked L-galactose 6-sulphate. The precise composition of porphyran shows seasonal and environmental variations. Porphyran is not used commercially, but the seaweed, Porphyra umbilicalis, is edible and is consumed in Wales (Laver). It is also made into a delicacy called Laverbread.
