<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>Neutral pentasasaccharide naturally present in human breast milk</p>

<p>Tetragalacturonic acid (α-1,4 galacturonotetraose) is derived from pectin or pectic acid by enzymatic or partial acid hydrolysis (Combo, 2012). It is used in galacturonic acid metabolism research as a substrate to identify, differentiate, and characterize endo- and exopolygalacturonase(s), and gluconase(s) (Jayani, 2005). The addition of very short fragments of homogalacturonan, tri-galacturonate, and tetra-galacturonate oligosaccharides restores development in dark-grown, de-etiolated seedling mutants, suggesting that they are unable to generate de-methylesterified pectin fragments. A model of spatiotemporally separated photoreceptive and signal-responsive cell types has been proposed, that contains overlapping subsets of the regulatory network of light-dependent seedling development (Sinclair, 2017).</p>

It has been used in the modification of saccharides and polysaccharides. This product is CAS No. 123809-61-0 and is available for custom synthesis. 1,2,4,6 tetra O acetyl 3 O-(2 3 4 6 tetra O acetyl a D galactopyranosyl) D galactopyranose is a high purity carbohydrate with glycosylation and fluorination.<br>END&gt; END&gt;</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>Sialyllactose-BSA is a complex carbohydrate that is used in the synthesis of saccharides. It has been modified with fluorination to create a 6'-sialyllactose-BSA, which is a monosaccharide. This product can be custom synthesized and it's purity is high. The product can be methylated or glycosylated, and it has been click-modified for fluorescence labeling.</p>

<p>Heparin derived disaccharide sodium salt is a salt form of heparin. It is a heterogenous mixture of low molecular weight compounds that are composed of sugar residues and sulfation. Heparin derived disaccharide sodium salt has been used for the treatment of thrombocytopenic purpura, thrombotic thrombocytopenic purpura, and other bleeding disorders. This drug also has been used to prevent blood coagulation in patients undergoing surgery.</p>

<p>Core antigen fragment in ABO blood group system</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>

<p>2-AB labeled core pentasaccharide found in most N-linked oligosaccharides.  Purified from the oligosaccharide pool released from bovine serum by hydrazinolysis using a combination of HPLC and glycosidase digestion.</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>

<p>Sodium alginate is the sodium salt of a polysaccharide obtained from brown seaweeds. The main use for alginate is in textile printing as a thickener in the printing of cottons with reactive dyes. In the food industry it is used as a thickener and gelling agent. The chemical structure consists of blocks of (1,4) linked-β-D-polymannuronic acid (poly M), (1,4) linked-α-L-polyguluronic acid (poly G) and alternating blocks of the two uronic acids (poly MG).</p>
