<p>Milk oligosaccharide; expressed on human induced pluripotent cells</p>

<p>This mixture contains some of the lower oligosaccharides found in human milk. There are small amounts of lactose but the bulk of the mixture are tri- and tetrasaccharides. 3-Fucosyllactose, 3'-Sialyllactose, 6'-Sialyllactose, Lacto-N-tetraose, Sialyllacto-N-tetraose b, Sialyllacto-N-tetraose b and Blood Group A tetrasaccharide type V are the major components that have been found in the mixture by chromatography but there may be other minor components not mentioned here.</p>

<p>4-O-(b-D-Mannopyranosyl)-D-glucose is a metabolite of D-mannose. It is a bacterial metabolite produced by Streptococcus pneumoniae that has been shown to inhibit the growth of bacteria by binding to the 50S ribosomal subunit. 4-O-(b-D-Mannopyranosyl)-D-glucose inhibits bacterial growth by binding to DNA dependent RNA polymerase, thereby preventing transcription and replication. The high frequency of human activity has been shown using a patch clamp technique on human erythrocytes. This active form is metabolized through a number of metabolic transformations, including hydrolysis by esterases or glucuronidases, oxidation by cytochrome P450 enzymes, reduction by glutathione reductase, or conjugation with glucuronic acid. Rifapentine also specifically binds to markers expressed at high levels in Mycobacter</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>

Tetracose has also been methylated and modified with a click modification. Tetracose has CAS No.: 145925-75-5</p>

<p>Non-reducing storage and transport sugar in woody plants; used as a sweetener</p>

<p>Blood group antigen derivative for biochemical research</p>

<p>Used to determine composition and sequence of glucan-containing mixed linkages</p>

<p>Glycyl-asialo, galactosylated fucosylated biantennary is a synthetic glycosylated oligosaccharide that is fluorinated at the 6-position. It has been shown to have high purity and good chemical stability. The carbohydrate is made from a complex of saccharides, which are linked together by glycosidic bonds. This product is available for custom synthesis with methylation and monosaccharide modifications. CAS No.: 128868-20-2</p>

<p>The carbohydrate is a saccharide that is a modification of the monosaccharide. It is synthesized from D-mannose and D-glucose and has a fluorination at the C4 position. The carbohydrate has been custom synthesized for high purity, methylation, glycosylation, and click modification.</p>

<p>Maltose (or malt sugar) is produced by the action of alpha- and beta-amylase on starch. Maltose is an intermediate in the intestinal digestion (i.e. hydrolysis) of glycogen and starch and is found in germinating grains (and other plants and vegetables). Maltose-containing syrups are used in the brewing, baking, soft drink, canning, confectionery, and other food industries (Collins, 2006). Maltose is also used in affinity purification of proteins using MBP-fused protein constructs. Herein, maltose is added to an elution buffer causing release of the MBP-fused protein from the resin.</p>

<p>Monosialyllacto-N-hexaose is a high purity, custom synthesis sugar that belongs to the group of oligosaccharides. This carbohydrate is modified with fluorination and glycosylation, which are Click modifications. Monosialyllacto-N-hexaose has a CAS number of 68638-04-3. This product is available for purchase in bulk quantities.</p>

<p>3-O-(a-D-Mannopyranosyl)-D-mannopyranose 1-O-propylamine acetate salt is a methylated saccharide. It is an oligosaccharide that can be synthesized from D-mannose and pyruvic acid, with the addition of a proton donor. This product is used in the synthesis of polysaccharides due to its high purity and low cost. The methyl group on this molecule reacts with the carbonyl group on the sugar to form an ester, which makes it resistant to hydrolysis by enzymes. 3-O-(a-D-Mannopyranosyl)-D-mannopyranose 1-O-propylamine acetate salt is also fluorinated and can be used as a click modification in proteins or carbohydrates.</p>

<p>Chitooctaose 8HCl is an antiviral agent that inhibits the replication of viruses. It blocks the virus from entering and infecting cells by binding to its receptor, which prevents cell-to-cell transmission. Chitooctaose 8HCl has a hydrolysable form and can be acetylated to increase its potency. This drug also interacts with ligands such as oligosaccharides, which are molecules consisting of several monomers linked together in a chain. The structural changes in these oligosaccharides are important for the interaction with chitooctaose 8HCl. Chitooctaose 8HCl has been shown to inhibit the replication of RNA viruses such as influenza A virus, human immunodeficiency virus type 1 (HIV-1), and rotavirus. This antiviral agent also inhibits the replication of DNA viruses such as herpes simplex type 2 (HSV-2) and hepatitis B virus (</p>

<p>3-O-(2-Acetamido-2-deoxy-a-D-galactopyranosyl)-D-galactopyranose is an endothelial cell growth factor that is generated by the enzymatic activity of galactosyltransferase. It binds to lectin, glycan, and monoclonal antibodies. This molecule has been shown to have biological properties that are related to cancer and immunology. 3-O-(2-Acetamido-2-deoxy-a-D-galactopyranosyl)-D-galactopyranose may be used as a glycolipid marker in blood group typing and in the detection of cervical cancer cells.</p>

<p>D-Melibiose monohydrate is a type of sugar that can be found in the extracellular space. It is also a component of fatty acids and has been shown to act as a growth factor for some cell types. D-Melibiose monohydrate has been characterized using tissue culture, growth factor profiles, and fluorescence detector. This sugar can be used as an alternative to trehalose in vitro assays, where it has been shown to have similar biological properties. D-Melibiose monohydrate may also be used for the manufacture of solid dispersions due to its solubility in organic solvents.</p>

<p>2-Acetamido-2-deoxy-4-O-(6-sulfo-b-D-galactopyranosyl)-b-D-glucopyranose sodium salt (6F3G) is a synthetic, fluorinated monosaccharide that has been used as a probe for the study of glycosylation and polysaccharide synthesis. 6F3G has been shown to be an effective inhibitor of the enzyme D-glycerate kinase, which catalyzes the conversion of D-glycerate to phosphoenolpyruvate. This inhibition leads to a decrease in the formation of ATP and NADH, which provides evidence that 6F3G binds to the active site of this enzyme.</p>
