  • Rhamnose Extract - China

    price: 35.00 Dollar US$

    CAS: 10030-85-0 Model: 98% specification: 98% Heavy metals: 10 (ppm) Uses: rhamnose can be used to determine the permeability of the intestine, can be used as a sweetener Product Name: L- Rhamnose Rhamnose the Appearance the properties: white powder Content: 98% (%) properties: mannose 6-position of a hydroxyl group is hydrogen-substituted derivatives, i.e., 6-deoxy-mannose -L-. Also known as methyl pentose. A type of typical 6-deoxyhexose that is juxtaposed with fucose. It is the sixth deoxygenated mannose, and finally becomes a compound of -CH3. It is naturally distributed in the L form, and is also called 6-de-oxy-L-mannose. Molecular formula: C6H12O5. It is most widely distributed in bacteria and plants. Polysaccharides or lipopolysaccharides in which rhamnose is composed of sugar are present on the cell surface. This sugar chain structure is often an antigen-specific factor. In the leaves and flowers of Rhus poisonodendron in plants, in addition to the form of free sugar, it is also distributed in the form of various glycosides such as rutin and a constituent sugar of a polysaccharide such as gum arabic. Plant source: widely distributed in plants as a trace of sugar. It can be present in the form of sugars in a wide variety of plant mites (such as ecdysis, iso Hesperidin, etc.), polysaccharides, especially pectins and gums, and may also be present in laccase toxins.
    The pathway for biosynthesis of rhamnose from glucose in bacterial cells is: α-glucose-1-phosphate→ dTOP-D-glucose→dTDP-4-k eto-6-deoxy-D-glucose→d TDP-4—discriminatory-L- rhamnose→ dTDP-L-rhamnose, the final product glyconucleotide is acted upon by each specific rhamnose-based transferase, and its rhamnose residue is incorporated into the glycoside and polysaccharide. Alias α-L-Rhamnopyranose, 6-Dexoxy-D-mannose, 6-Deoxy-L-mannose, Isodulcite, L-Mannomethylose, D-Rhamnose, L-Rhamnose are mostly L-form in nature and are widely found in plant polysaccharides. Glycoside, vegetable gum and bacterial polysaccharides. Its sweetness is 33% physical properties of sucrose : pure rhamnose is a colorless crystalline powder, soluble in water and methanol, slightly soluble in ethanol, and its crystal forms in two forms, α type and β type. The α type contains one molecule of crystal water, and loses crystal water after heating, and is converted into β type (molecular weight: 164.16); the β type is extremely hygroscopic, and absorbs moisture in the air to form α type. The common one is α-L-rhamnose, its molecular weight is 182.11. Under the usual conditions, aL-rhamnose monohydrate crystals, flake crystals, melting point 82-92℃, specific optical rotation -7.7 ° → +8.9 °, soluble In water and ethanol; β-L-rhamnose (anhydrous) is hygroscopic in needle-like crystals, melting point 122-126℃, +38.4 ° → +8.9 °, soluble in water and ethanol. It has a sweet taste and exists in the form of pyran in an aqueous solution. It has reducibility, oxidizes with bromine water to form rhamnic acid, and is oxidized by nitric acid to form L-arabic serotonic acid. The use of sodium amalgam is also the principle of rhamnose alcohol. Uses: rhamnose can be used to determine the permeability of the intestine, can be used as a sweetener
