CAS:<p>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.</p>Pureza:Min. 95%Forma y color:PowderXyloglucan
CAS:Xyloglucans are members of a group of polysaccharides typically refered to as hemicelluloses. Hemicelluloses are plant cell wall polysaccharides that are not solubilized by water but are solubilized by aqueous alkali (e.g. 1 and 4M KOH). Other hemicellulosic polysaccharides include xylan, glucuronoxylan, arabinoxylan, mannan, glucomannan and galactoglucomannan. Hemicelluloses have a backbone of 1,4-linked β-D-pyranosyl residues in which O4 is in the equatorial orientation (e.g. Glc, Man, and Xyl). Xyloglucan is the predominant hemicellulose in the primary walls of dicots and non-graminaceous monocots and may account for up to 20% of the dry weight of the primary wall. Xyloglucan has a backbone composed of 1,4-linked β-D-Glcp residues. Up to 75% of these residues are substituted at O6 with mono-, di-, or triglycosyl side chains.Pureza:(Dry Basis) Min. 95%Forma y color:PowderChondroitin sulfate A sodium from bovine trachea
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.Pureza:Min. 95%Forma y color:Powder(Hydroxypropyl)methyl cellulose - USP39, Viscocity 3000-5600 cP

CAS:<p>Methyl cellulose is a synthetic polymer of cellulose. It is prepared by treating the natural polymer with a methylating agent, such as dimethyl sulfate. Methylation is carried out in the presence of an acid catalyst to produce mainly methyl ethers and methyl esters. The degree of substitution may be controlled by the amount of catalyst. Methyl cellulose is used as a thickener, emulsifier, or stabilizer in many food products, including ice cream and toothpaste.</p>Pureza:Min. 95%Rhamnogalacturonan - from potato
CAS:<p>Pectin is a highly complex polysaccharide matrix that is found in the primary walls of dicotyledenous and monocotyledenous plants and gymnosperms, including potato. A key fragment of this complex is rhamnogalacturonan I, containing a backbone of the repeating disaccharide [-4)-α-D-GalpA-(1,2)-α-L-Rhap-(1,]. Several applications for RG1 have been described including drug targeting to the colon via the oral administration route for local treatment of e.g. inflammatory bowel disease and colon cancer. This has several advantages such as needle-free administration and low infection risk. In the gastro-intestinal tract RG-I is only degraded by the action of the colonic microflora. High purity rhamnogalacturonan I is also used in research, biochemical enzyme assays and in vitro diagnostic analysis.</p>Pureza:Min. 95%Fluorescein isothiocyanate-carboxymethyl-dextran - Average MW 4,000
