Starch from potato
CAS:<p>Starch is an energy storing polysaccharide produced by higher plants and some algae. Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. It consists of two types of polysaccharide: the linear and helical amylose (α-1,4-linked glucose) and the branched amylopectin (α-1,4 and α-1,6-linked glucose). Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight.</p>Forma y color:White PowderLM Pectin
CAS:<p>Pectins are regarded as linear chains of α-1,4-linked D-galacturonic acid, a homogalacturonan (pectic acid). In the products of commerce, the degree of methylation has a vital influence on the properties of pectin, especially the solubility and gel forming characteristics.</p>Forma y color:PowderArabinan
CAS:<p>Sugar beet arabinan consists of a 1,5 α-linked arabinose backbone to which 1,3 α-linked (and possibly some 1,2 α-linked) L-arabinofuranosyl residues are attached. Approximately 60% of the main-chain arabinofuranosyl residues are substituted by single 1,3-linked arabinofuranosyl groups. The reducing terminal arabinosyl residue is attached through rhamnose to fragments of the rhamnogalacturonan backbone of the native pectin molecule.</p>Forma y color:White PowderHydroxypropyl cellulose - Average MW 80,000
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%Glycogen - from oyster for molecular biology
CAS:<p>Glycogen is a highly branched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. It is the main storage form of glucose in the body. In humans, glycogen is made and stored primarily in liver and muscle cells and functions as the second most important energy storage molecule to fat which is held in adipose tissue. Glycogen is analogous to starch and has a structure similar to amylopectin, but is more extensively branched and compact than starch. It occurs as granules in the cytosol/cytoplasm in many cell types, and plays an important role in the glucose cycle.</p>Pureza:Min. 95%Fluorescein isothiocyanate-dextran - Average MW 70,000

CAS:<p>Pectins are regarded as linear chains of α-1,4-linked D-galacturonic acid, a homogalacturonan (pectic acid). In the products of commerce, the degree of methylation has a vital influence on the properties of pectin, especially the solubility and gel forming characteristics. Commercial high methoxy (HM) pectin has > 70% of hydroxyl groups methyl esterified. HM pectin forms gels in the presence of sucrose and for this reason it is used in jams often in combination with other fruits.</p>Pureza:(%) Min. 85%Forma y color:PowderFluorescein isothiocyanate-dextran - Average MW 20,000

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:PowderHydroxyethyl cellulose - Viscocity 4500-6500mPa·s

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
