Polysaccharides

Wy-45494 (hydrochloride) (Standard) is the analytical standard of Wy-45494 (hydrochloride). This product is intended for research and analytical applications. Wy-45494 hydrochloride (N-Desmethyl Venlafaxine hydrochloride; Wy 45494) is a minor active metabolite of the selective norepinephrine and serotonin reuptake inhibitor (SNRI) venlafaxine. It is formed from venlafaxine via the cytochrome P450 (CYP) isomer CYP3A4.2. Wy-45494 hydrochloride inhibits norepinephrine and serotonin reuptake in rat synaptosomal preparations (IC50s of 4.7 and 1.6 μM, respectively). In vivo, Wy-45494 hydrochloride reversed reserpine-induced hypothermia in mice at a minimum effective dose (MED) of 10 mg/kg.

Allyl β-lactoside (Allyl β-D-lactose) is a lactoside, which can be generated by incubating lactose and allyl alcohol with cellulase preparation, and can be used as a starting material for the synthesis of glycopolymers.

Chitosan octaacetate is a form of chitosan containing eight acetic acid groups, which is formed by the acetylation of chitin. Chitosan octaacetate can be used to synthesize chitosan oxazoline and other chitinoid precursors.

Monofucosyllacto-N-hexaose III (MFLNH III) is a kind of neutral human milk oligosaccharides (HMO).

β,β-Trehalose is a analog of trehalose. β,β-Trehalose can support the growth of shoot tips of Cuscuta. β,β-Trehalose can be cleaved by nonspecific β-glucosidase.

Difucosyllacto-N-neohexaose is an oligosaccharide that can be isolated from human milk.

Lacto-N-fucopentaose III (LNFP-III) is an immune modulator. Lacto-N-fucopentaose III reduces the severity of experimental autoimmune encephalomyelitis (EAE) and CNS inflammation.

Lacto-N-difucohexaose I (LNDFH I), a linker, could be used to combine oligosaccharides containing Lewis b sugar chain to water insoluble polysaccharide.

Lacto-N-neodifucohexaose II (LNnDFH II) is a neutral difucosylated human milk oligosaccharide (HMO). Lacto-N-neodifucohexaose II is a characteristic HMO associated with the non-secretor phenotype in human milk, and its concentration pattern is positively correlated with the colonization of B. breve in the infant gut.

Difucosyl-para-lacto-N-hexaose II (DFpLNH II) is a biochemical reagent that can be used as a biological material or organic compound for life science related research.

γ-Cyclodextrin hydrate is an orally active cyclic oligosaccharide composed of eight glucose molecules, which can be formed by bacteria digesting starch. γ-Cyclodextrin hydrate can form water-soluble inclusion complexes with a variety of poorly soluble compounds and is widely used in fields such as pharmacy and food. In addition, γ-Cyclodextrin hydrate has good safety.

Blood group A pentasaccharide (A-Pentasaccharide), an oligosaccharide in urine, can inhibit the binding of anti-A antibody to blood group A substance.

Cellopentaose is a penta oligosaccharide of cellulose.

Gangliotetraose (Gg4) is a tetrasccharide, exhibits major components including GM1 and its sialylated derivatives. GM1 facilitates efflux of nuclear Ca²⁺ and reduces the level of nuclear Ca²⁺ that characterizes the differentiated neuron. GM1 affects neuronal plasticity and repair mechanisms, as well as neurotrophin release in the brain.

Blood group A antigen tetraose type 5 (A-Tetrasaccharide) is a tetrasaccharide and a blood group specific oligosaccharide, inhibits the binding of anti-A antibody to blood group A substance. Blood group A antigen tetraose type 5 can be isolated from polar bear milk samples.

GM1a Ganglioside oligosaccharide is a semisynthetic form of ganglioside GM1. Ganglioside GM1 is the natural receptor for cholera toxin and plays an important role not only in general growth regulation but also in the coupling of hormone-induced responses.

Blood-group A trisaccharide (A-Trisaccharide) is a oligosaccharide present in the urine of blood group A secretors.

Isoglobotetraose (Globoisotetraose) is the oligosaccharide moiety of human glycosphingolipids. Synthesis process: globotetraose (GalNAcβ1→3Galα1→4Galβ1→4Glc) and isoglobotetraose (GalNAcβ1→3Galα1→3Galβ1→4Glc).

Cellooctaose is an oligosaccharide, consisting of eight glucose residues. Cellooctaose is a low-cost polysaccharides in fermentation to hold on Lactococcus lactis recombinant strain growth. Cellooctaose is the substrate of beta-glucosidase (E.C. 3.2.1.21).

Polypectate sodium is a major component of cell wall polysaccharides (pectins) and is used as a carbon source and inducer of polygalacturonase. Polypectate sodium can also be used to evaluate alkaline active and alkaline stable pectate lyases from Streptomyces spp. and to study the optimization of polygalacturonase production from Xanthophyllum spp. and reaction conditions.
