<p>Sucralfate is a drug that is used to treat and prevent injury-related inflammation by forming a protective barrier on the lining of the stomach and duodenum. Sucralfate has been shown to be effective in the treatment of infectious diseases, such as viral or bacterial infections, and also for radiation enteritis and ulcerative colitis. Sucralfate may interfere with the absorption of other drugs, such as acyclic nucleoside phosphonates, which are used to treat HIV/AIDS. This drug has also been shown to have anti-inflammatory properties through inhibition of prostaglandin synthesis. Sucralfate has been shown to have anti-inflammatory properties through inhibition of prostaglandin synthesis.</p>

<p>This mixture contains some of the penta- and hexasaccharides in human milk.</p>

<p>The hyaluronic acid discaccharide and other enzymatically produced polymer homologs from hyaluronic acid have been of value in the study of hyaluronic acid metabolism in healthy and diseased tissues (Hascall, 2019). Hyaluronic acid is a polysaccharide containing repeating disaccharide units of β-1,3-N-acetyl glucosamine and β-1, 4-glucuronic acid. The unsaturated disaccharide hyalobiuronic acid is released from hyaluronic acid by the action of hyaluronidase on umbilical cord (Weissman, 1954).</p>

<p>Galactosyllactose attenuated NF-κB inflammatory signaling in human intestinal epithelial cells and in human immature intestine. Thus, galactosyllactoses are strong anti-inflammatory agents in human colostrum and early milk, contributing to innate immune modulation. This product has a 13C heavy-label and so can be used in applications such as metabolic tracing and quantitative mass spectrometry.</p>

<p>A tetra-O-acetyl-6-O-(2,3,4,6-tetra-O-acetyl-a-D-galactopyranosyl)-b-D-thioglucopyranose is a 1,2,3,4 tetraol. It is synthesized by the modification of a disaccharide that has been modified with fluorine and methyl groups on the C1 and C4 positions of the sugar. The complex carbohydrate is a glycosylated sugar that is composed of one monosaccharide and one oligosaccharide. This product is CAS No. 1820574-50-2.</p>

<p>4-O-(b-D-Galactopyranosyl)-b-D-thioglucopyranose is a custom synthesis carbohydrate. It is an oligosaccharide that consists of a monosaccharide with a b-D-galactopyranosyl group and a b-D-thioglucopyranose group. 4-O-(b-D-Galactopyranosyl)-b-D-thioglucopyranose is a polysaccharide and belongs to the class of carbohydrates, which are saccharides or sugars. Carbohydrates are important in cell walls and are modified by methylation, glycosylation, and click modification. Carbohydrates can be classified as simple or complex carbohydrates. Simple carbohydrates contain one molecule with one type of sugar unit bonded together, while complex carbohydrates have more than one type of sugar unit bonded together.</p>

<p>Detergent used for the solubilization of membrane proteins.  Important for the solubilization is the detergent-to-protein ratio. At low ratios (1:10) the membranes are lysed and large complexes of are formed containing protein, detergent, and membrane lipids. With progressively larger ratios smaller complexes are obtained. Finally, at ratios of 10:1 to 20:1 individual detergent-protein complexes are formed free of membrane lipids. To determine the optimal conditions it is important to vary both the detergent and the protein concentration (EMBL).</p>

<p>GD3 ganglioside (shown as sodium salt) has a core disaccharide structure (Gal-1,4-Glc) with two sialic acids linked to the non-reducing galactose residue, and ceramide linked to position 1 on the reducing terminal glucose residue (Ledeen, 2009). GD3 ganglioside is a minor ganglioside in most normal tissues but plays a crucial role in the development of the brain; its presence is significantly reduced in adults. However, expression of GD3 ganglioside is increased in pathological conditions, such as, cancers and neurodegenerative disorders (Malisan, 2002). GD3 ganglioside was the first cancer-associated ganglioside discovered, that promotes adhesion and invasion of cancers. GD3 ganglioside and GD2 ganglioside are highly expressed in a various malignant cancers and have become potential targets for next-generation cancer therapy (Liu, 2018).</p>

<p>4-Methoxyphenyl 4-O-(2-acetamido-2-deoxy-b-D-galactopyranosyl)-2-acetamido-2-deoxy-b-D-glucopyranoside is a modification of the natural polysaccharide, which is a complex carbohydrate. It is synthesized by our high purity, custom synthesis service and can be modified with methylation, fluorination, or glycosylation. This product has been proven to have high purity and stability in the past.</p>

<p>b-D-(2-Acetamido-2-deoxy-D-glucopyranosyl)-2-acetamido-2-deoxy-b-D-thioglucopyranoside is an oligosaccharide that belongs to the carbohydrate class. It is a fluorinated monosaccharide with a high purity and custom synthesis. This compound is methylated and glycosylated, making it a complex carbohydrate with click modification.</p>

<p>GD2 oligosaccharide is the core trisaccharide structure of the ganglioside GD2 (sodium salt) (GalNAcβ1,4Galβ1,4Glc) with its two sialic acids linked α2,3/α2,8 to the central galactose residue (Ledeen, 2009). GD2 ganglioside is expressed at a low concentration in the central nervous system, nerves, skin melanocytes and stem cells in healthy adults. On the other hand, GD2 ganglioside is overexpressed in a number of tumors, including: neuroblastoma, melanoma, small cell lung carcinoma and brain tumors. Recently, GD2 ganglioside has been found in low concentrations on breast cancer stem cells (CSC) that possess: self-renewal properties (division without disrupting the undifferentiated state) and tumor-initiating capabilities. It has been suggested that GD2 ganglioside may be developed as an effective target antigen for CSC immunotherapy (Fleurence, 2017).</p>
