CAS:This β-glucan contain D-glucose residues with β-1,3 links and b-1-6 side branches. The frequency, location, and length of the sidechains may play a role in immunomodulation. Differences in molecular weight, shape, and structure of β-glucans can also affect the differences in biological activity. The water-soluble β-D-glucan is extracted from fruiting bodies of Piptoporus betulinus by hot aqueous extraction, followed by freeze-thawing and dialysis. Methylation analysis and NMR spectroscopy, indicated the presence of a β-D-glucan with a main chain (1,3)-linked, substituted at O-6 by single glucose residues.

CAS:Fórmula:(C6H10O5)nForma y color:White or off-white powderPeso molecular:-Xyloglucan
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:(%) Min. 95%Forma y color:Powder4-Nitrophenyl N,N',N''-Triacetyl-β-chitotrioside

CAS:Carboxymethyl chitosan has good solubility in water and unique chemical, physical and biological properties such as high viscosity, large hydrodynamic volume, low toxicity, biocompatibility and good ability to form films, fibres and hydrogels. For this reason, it has been extensively used in many biomedical fields such as a moisture-retention agent, bactericide, wound dressing agent, in artificial bone and skin, as blood anticoagulant and as a component in different drug delivery matrices. The reactive ligands COOH and NH2 groups are available for metal chelation and dye binding.Forma y color:White PowderD-Galactan [for Plant-based Organic Molecular Catalyst]
