Oligosacáridos

<p>N-Acetyl-D-lactosamine (LacNAc) is a natural structural element in a variety of glycoconjugates, found in milk, urine, meconium and glyciproteins. It’s a substrate for galactosidases, fucosyltransferases, and sialyltransferases. This LacNAc is also useful as a lectin inhibitory sugar and for characterizing lectins.</p>

<p>Lactose is the principal sugar in human and most other mammalian milks, ( 4-O-(beta-d-galactopyranosyl)-d-glucopyranose). Lactose undergoes mutarotation; it is a reducing sugar and is significantly less soluble in water than sucrose. Lactose is much less sweet than sucrose (at ~1% about 0.15 (sucrose=1). The enzyme lactase (beta-galactosidase), which is present in the small intestine, catalyzes hydrolysis of lactose to form glucose and galactose. Anhydrous lactose is an excipient, filler, diluent, and bulking agent in a wide variety of pharmaceutical tablets, capsules, powders and other preparations. Lactose also has applications as a nutrient and multi-functional ingredient in infant formulae, geriatric, dietetic and health foods.</p>

<p>Linear B-2 trisaccharide is a human serum glycoprotein that belongs to the group of glycoconjugates. It has been shown to have clinical relevance in the detection of cancer and infectious diseases, as well as for use in the treatment of cancer. Linear B-2 trisaccharide can be used in combination with monoclonal antibodies for diagnosis and treatment of cancer. This molecule is also an inhibitor of both influenza virus hemagglutinin and HIV gp120, which may be due to its ability to react with specific carbohydrate structures on these proteins. Linear B-2 trisaccharide is biocompatible and can be used in the development of biodegradable polymers. The linearity of this molecule makes it more stable than other related molecules, such as glycopeptides.</p>

<p>Chitinases are enzymes that hydrolyze chitin, a polysaccharide found in the exoskeleton of insects, fungi and other invertebrates. Chitohexaose is a sugar that has been shown to have anti-inflammatory properties. It is a carbohydrate with six acetyl groups attached to it. When this sugar reacts with ammonium bicarbonate (NH4HCO3) in an acidic environment, it produces N,N',N'',N''',N'''',N''''',N''''''-heptaacetylchitoheptaose. This reaction system can be used as a chitinase preparation for investigating the biological effects of chitohexaose. The magnetic resonance spectroscopy was used to study the reaction system and revealed that the product is a hexamer with six acetyl groups on each monomer.</p>

<p>2-Amino-2-deoxy-3-O-(b-D-glucopyranuronosyl)-D-galactopyranose monohydrate is a glycoside that is found in the testes. It has inhibitory properties on oligosaccharides and can be used to study the structure of glycoconjugates. 2-Amino-2-deoxy-3-O-(b-D-glucopyranuronosyl)-D-galactopyranose monohydrate has been shown to inhibit the enzyme hydrolase, which is involved in glycoprotein synthesis. 2ADOGP has also been shown to bind to human serum albumin, an abundant protein in human blood plasma that transports lipids, hormones, and other molecules throughout the body. This binding results in a decrease in the serum concentration of 2ADOGP after administration.</p>

<p>4-Methoxyphenyl 2,3,6-tri-O-acetyl-4-O-(2,4,6-tri-O-acetyl-3-O-allyl bDgalactopyranosyl)-bDglucopyranoside is a modification of an oligosaccharide. It is a high purity and custom synthesis. This product can be found under CAS No. 807827-28-0.</p>

<p>4,6-O-Benzylidene-D-maltose is an oligosaccharide that is a high purity custom synthesis. It has a Click modification and can be synthesized using the Fluorination and Glycosylation reaction. 4,6-O-Benzylidene-D-maltose is soluble in water and ethanol, but insoluble in ether. This product is listed as CAS No. 93417-41-5 and has a Methylation modification. 4,6-O-Benzylidene-D-maltose is also found in saccharides, carbohydrates, and complex carbohydrates.</p>

<p>1,2-a-1,2-a-D-Mannotriose 1-O-propylamine acetate salt is a synthetic oligosaccharide.</p>

<p>GM2-oligosaccharide (sodium salt) is a trisaccharide (GalNAcβ1,4Galβ1,4Glc) with sialic acid linked α2,3 to the central galactose residue (Ledeen, 2009). The parent GM2 ganglioside is present on neuronal cells and plays a key role in the regulation of dendritogenesis in cortical pyramidal neurons. In lysosomal storage disorders, such as, Tay-Sachs and Sandhoff disease, where hexosaminases A and B are deficient, GM2 ganglioside accumulates in the nervous system (Cachon-Gonzalez, 2018). GM2 ganglioside is also overexpressed in melanomas and other tumours of neuro-ecto origin (Yoshida, 2020). Moreover, the sugar moiety of GM2 ganglioside is a receptor allowing viral infection of cells with reovirus and rotavirus (Zhu, 2018).</p>

<p>a1-3 linked isomer of globotetraose</p>

<p>Lactulose is a non-absorbable sugar used in the treatment of constipation and hepatic encephalopathy. It is used by mouth for constipation and either by mouth or in the rectum for hepatic encephalopathy. It generally begins working after 8-12 hours, but may take up to 2 days to improve constipation.</p>

<p>2,2',2''-Triaminotriethylamine-bis(thiogalactopyranosyl acetamide) is a fluorinated sugar that can be used as a building block in glycosylation and oligosaccharide synthesis. It has been shown to be useful for the preparation of complex carbohydrates with desired properties such as high purity.</p>

<p>Cellotriose is a bifunctional sugar that can be chemically converted to cellobiose and D-cellopentaose. Cellotriose is a component of cellulose, which is the most abundant biopolymer on Earth. Cellotriose is a source of chitin, which is a major component of the exoskeleton of insects and crustaceans. The molecule has been observed using atomic force microscopy to have an amphiphilic nature, in that it has both hydrophobic and hydrophilic regions. Cellotriose has been synthesized in the laboratory for use as an artificial sweetener, but it does not taste as good as sucrose because it lacks the sweetness profile. When heated, cellotriose undergoes a color change from yellow to blue-green due to its ability to form hydrogen bonds with oxygen molecules. This property can be used as a colorimetric test for cellulase activity in solutions.</p>

<p>4-Methoxyphenyl 4-O-(4,6-O-benzylidene-3-O-tert-butyldimethylsilyl-2-O-levulinoyl-b-D-glucopyranosyl)-3,6-di-O-benzyl -2,6'-dideoxygalactopyranoside is a modification of the natural carbohydrate galactose. The sugar moiety has been methylated and glycosylated with a levulinate ester and then fluorinated. This compound is highly pure and can be synthesized on custom order.</p>

<p>GA2-ganglioside is a ganglioside that is found in the membranes of cells. GA2-Ganglioside has been shown to inhibit the growth of tumors by binding to macrophages and T cells, which are two types of white blood cells. It has also been shown that GA2-Ganglioside can be used as a target for an antibody response against human HL-60 tumor cells. The antibody response induces cell lysis and reduces the size of the tumor. GA2-Ganglioside has also been shown to have anti-inflammatory properties, which may be due to its ability to bind to α subunits on bowel disease and infectious diseases, such as murine sarcoma virus, causing an antibody response that causes cell lysis and prevents replication of these viruses.</p>

<p>The ‘tallowate’ esters are probably the best known derivatives of sucrose and many attempts have been made to commercialise them in order to exploit their excellent surfactant functionalities.  The most functional products are the mono- and diesters of the tallow acids (stearic, palmitic, oleic) with hydrophile-lipophile balance (HLB) values that lend themselves to surfactant applications in foods and cosmetics.  They also have other uses, for example in coating fruits with a semipermeable membrane that acts as a preservative.  Manufacturing economics have prevented these products from mass production and they remain in niche applications.</p>

<p>Chitobiose-6'-phosphate is a carbohydrate that is used in the synthesis of oligosaccharides. It can be modified to produce different types of saccharides, such as methylation, saccharide click modification, and modification. Chitobiose-6'-phosphate is available in high purity and offers a custom synthesis service for specific requirements.</p>
