<p>D-Melibiose anhydrous is a disaccharide that is used as an excipient in the pharmaceutical industry. It has been shown to be an active enzyme, which may be due to its ability to sequester galactose. D-Melibiose anhydrous has a redox potential of -0.2 V, indicating that it has a high number of oxidizable groups. The molecular weight of this sugar is 324.14 g/mol, and it has a polarizability of 0.16 D, which classifies it as a polyol with hydrogen bonding properties. This sugar is not soluble in water but can be dissolved in ethanol or propylene glycol. D-Melibiose anhydrous also has carbohydrate properties and may be considered a sugar alcohol because it contains six carbon atoms and one oxygen atom.</p>

<p>3'-b-Sialyl-N-acetyllactosamine is an oligosaccharide that is synthesized from L-arabinose and 3'-phosphoadenosine 5'-phosphosulfate. It has a high degree of purity and is custom synthesized to order. The CAS number for this product is 210418-18-1.</p>

<p>Trehalose 6-octanoate is a modified form of trehalose that has been synthesized and fluorinated. It is a monosaccharide, which means it is one of the simplest forms of sugar. Trehalose 6-octanoate is an oligosaccharide, which means it is a sugar molecule made up of several smaller sugar molecules. This sugar can be modified to include methyl groups, making it a polysaccharide. Polysaccharides are complex carbohydrates that can often be found in plants or animals. Trehalose 6-octanoate is used in the modification of proteins and lipids for the production of pharmaceuticals and other products.</p>

<p>Lipid IVA is a tetra-acylated precursor molecule of lipid A which is a component of lipopolysaccharides (LPS) on the outer membrane of gram-negative bacteria. On the innate immune cells of hosts there are toll-like receptor 4 (TLR4) and MD-2 which recognize LPS. This recognition event ultimately leads to the activation of NFκB which in turn results in pro-inflammatory cytokine production. Studies have suggested lipid A in Escherichia coli to be an agonist for both mouse and human TLR4, while lipid IVA can induce species specific TLR4 responses. For example for horse and mouse TLR4 and MD-2, Lipid IVA is an agonist where as it is an antagonist for TLR4 and MD-2 in humans.</p>

Chondroitin sulphate is an inhibitor that has been extensively studied in human and animal models. This active agent has been shown to have a protein inhibitory effect on epithelial cells, as well as an inhibitory effect on cell growth in Chinese medicine and Chinese medicinal plants. Chondroitin sulphate has been found to exhibit inhibitory activity against endothelial cells, which may be due to its ability to inhibit the nuclear translocation of NF-κB. This compound can be detected by liquid chromatography and has been shown to have a significant inhibitory effect on the proliferation of HepG2 cells. Overall, chondroitin sulphate shows great potential for use in healthcare products aimed at regulating cell growth and inflammation.

<p>Chondroitin disaccharide di-6S (CDD6S) is a synthetic, fluorinated oligosaccharide that is used for glycosylation and modification of proteins, polysaccharides, and other biomolecules. It has been shown to be effective in inhibiting the growth of cancer cells by targeting the sugar moiety on cell surface receptors. CDD6S has been modified with methyl groups at various positions on the sugar chain to increase its activity against certain cancers.</p>

<p>Maltotridecaose is a sugar alcohol with an acceptor group that can be introduced into a cavity in a molecule. It is a sweetener that has been shown to have oligosaccharide properties, which are the molecules that comprise dietary carbohydrates. Maltotridecaose can be found as an unlabeled ingredient in foods such as sugar-free chewing gum, chocolate, and ice cream. The debranching of maltotridecaose occurs by way of glucans and licheniformis.</p>

<p>Safflor Yellow A is a natural drug that has been shown to have hypoglycemic effects. It is a potent inhibitor of glucose-6-phosphatase and glucose-6-phosphate dehydrogenase, which are enzymes involved in the conversion of glucose to glycogen. Safflor Yellow A also inhibits neuronal death, as it blocks the enzyme activities that lead to neuronal cell death. This drug has also shown antitumor activity, as it induces apoptosis in tumor cells. Safflor Yellow A also has antihyperlipidemic effects and can be used for the treatment of coronary heart disease. Low doses of this drug have been shown to reduce systolic pressure in rats and improve blood coagulation. The mechanism of action for this drug is not yet known but may involve toll-like receptor 4 signaling pathways or polymerase chain reaction (PCR).</p>

<p>Monofucosyllacto-N-hexaose II is a tetraol that is used as a reagent in the synthesis of enantioenriched and synthetically tetrasaccharidic products. Monofucosyllacto-N-hexaose II can be obtained by the reaction of Grignard reagents with glucose or by stereoselective reduction of an alpha, beta unsaturated ketone. The presence of the glucose residue in Monofucosyllacto-N-hexaose II makes it an acceptor for esterification reactions. This compound has chiral centers due to its two stereogenic centers at C2 and C3, which are both beta positions on the glucose residue. Monofucosyllacto-N-hexaose II also has a free hydroxyl group at C5 that can be esterified to produce chiral esters.</p>
