It has been shown to be an acceptor for episulfide and an 1-deoxy-d-ribulose. 2-C-Methyl-D-ribono-1,4-lactone has been found to yield dimethylamine when heated with magnesium. This compound can be ion exchanged with calcium and magnesium. 2CMR was first synthesized by the reaction of L(+) lactic acid with dimethylamine in the presence of magnesium chloride. The product was purified by crystallization from water, yielding a white powder that melts at 230°C.

<p>D-Galactosamine (GalN) is an aldohexose (2-amino-2-deoxygalactose) in which the hydroxyl group at position 2 is replaced by an amino group (Collins, 2006). Galactosamine (as the N-acetyl derivative) forms a key part of both N- and O-linked glycoproteins, glycolipids and glycosaminoglycans. Treatment of experimental animals with D-galactosamine / lipopolysaccharide causes lethal liver injury characterized by apoptosis of the hepatocyte and it is used as a laboratory model to study the effect of therapeutic agents (Hirono, 2001).</p>

<p>Sucrose-6-acetic ester is a product of the reaction between sucrose and acetic anhydride. It is a white crystalline compound that reacts with chlorinating agents to form sulfoxide compounds. Sucrose-6-acetic ester can be converted to acetylsalicylic acid, which is used to synthesize aspirin. The reaction selectivity of this process relies on the enzyme catalysis of acetylation and triphosgene as well as an acidic or basic catalyst. Acetylation is carried out in organic solvents and requires a crystallization process for purification. This product also has fatty acid properties, which are insoluble in water and other polar solvents.</p>

<p>1,3,4,6-Tetra-O-acetyl-2-azido-2-deoxy-a-D-galactopyranose is an azide sugar that is resistant to the activity of sulfide and can be used as a probe for sulfide in the distal colon. It has been shown that this sugar binds to recombinant human erythrocyte enzymes and inhibits their activities. The hydrolysis of this sugar by pancreatic enzymes has been shown to be dependent on the conformational state of the enzyme. This sugar also inhibits salivary amylase and intestinal sucrase activities.</p>

<p>Mucic acid is a metal chelate that stimulates the metabolism of carbohydrates, fats and proteins. It also plays a role in the production of energy in the body. Mucic acid has been shown to have a protective effect against infectious diseases, as it activates toll-like receptor 2 (TLR2) and TLR4, which are molecules involved in innate immunity. Mucic acid has been shown to protect against influenza virus infection by increasing the expression of interferon-gamma (IFN-γ) and IL-12, which are cytokines that inhibit viral replication. Mucic acid can be used as a fluorescence probe for detection of polymorphonuclear leucocytes in blood samples.</p>

<p>1,2,3,4,6-Penta-O-benzyl-b-D-thiogalactopyranoside is a custom synthesis that is a complex carbohydrate. It has a CAS number of 210358-01-3 and a molecular weight of 603. It is modified with saccharide, methylation, glycosylation, and carbonyl groups. This product is available in high purity and without fluorination or synthetic modification.</p>

<p>2,3,4,6-Tetra-O-benzoyl-1-deoxy-D-arabino-hex-1-enopyranose is a glycosyl compound that has been synthesized by the elimination of trifluoride and alcohols. It is used as a starting material for the synthesis of other compounds. This compound can react with halides to form etherate or ester derivatives. 2,3,4,6-Tetra-O-benzoyl-1-deoxy-D-arabino hexane can also be reacted with boron trifluoride or boron trifluoride etherate to form eliminations.</p>

<p>1-Deoxy-L-mannitol is an effective oral hypoglycemic agent that has been used in the treatment of diabetes. It is a sugar alcohol with a chemical structure similar to glucose and erythritol. 1-Deoxy-L-mannitol is absorbed by the small intestine and enters the bloodstream after being hydrolyzed by pancreatic enzymes. It inhibits fatty acid synthesis, which leads to decreased levels of acetyl coenzyme A and increased levels of carnitine, leading to activation of fatty acid oxidation in liver cells. This drug also inhibits phosphatase activity, which leads to decreased production of glycerophosphate from triphosphate. This process results in an increase in intracellular pH and a decrease in plasma glucose concentration. The use of 1-deoxy-L-mannitol for the treatment of diabetes was first reported by George Cahill and his colleagues at Harvard University in 1967. It was shown that this drug could reduce blood sugar</p>

<p>3,4-Di-O-acetyl-D-fucal is a synthetic carbohydrate with two orientations. It is a synthon for the synthesis of carbohydrates and can be used as a ligand in biomolecular design. The synthetic carbohydrate has been shown to have chemotherapeutic effects, which may be due to its ability to inhibit glycan synthesis. This synthetic carbohydrate also has conformational parameters that are similar to those of natural fucose, which makes it an attractive candidate as a potential drug target.</p>

<p>N1-a-L-Arabinopyranosylamino-guanidine HCl is a carbohydrate that belongs to the class of oligosaccharides. It is a synthetic compound, which is custom synthesized for use in research.

<p>D-Threitol is a carbohydrate that has been shown to have anti-microbial activity against a number of microbes, including E. coli, Klebsiella pneumoniae, Bacillus subtilis, and Staphylococcus aureus. It may also be useful in the treatment of microbial infections in the respiratory tract. D-Threitol is an analogue of threitol with an acyl chain at the 4 position instead of the 5 position. The allyl carbonate moiety can be cleaved by acid to form an acid complex, which is more stable than D-threitol. D-Threitol binds to antibody response sites on cells, thereby preventing cells from responding to pathogens or other foreign bodies by initiating appropriate immune responses. This binding also prevents bacteria from attaching themselves to cell walls.</p>

<p>Methyl 3,5-di-O-benzyl-b-D-ribofuranoside is a synthetic glycoconjugate. The methyl group at the 3 position of the ribose is substituted with a fluorine atom. This modification results in increased resistance to nucleases and enhanced cell penetration. Methyl 3,5-di-O-benzyl-b-D-ribofuranoside can be used for the synthesis of complex carbohydrates that are not accessible by other methods.</p>

<p>Cochineal is a natural dye that is extracted from the female cochineal insect. Cochineal is used in food and cosmetics, and as a red colorant in some pharmaceutical products. The carminic acid present in cochineal forms a stable complex with the anionic groups present in wool or silk, so it is not soluble in water. Cochineal has been shown to have genotoxic activity and can cause mutations at both the base-pairing level and at protein level. Cochineal has also been shown to be cytotoxic against human serum cells and disrupt mitochondrial membrane potential. Its optimum concentration for signal peptide detection by electrochemical impedance spectroscopy (EIS) was found to be 0.1 mM.</p>

<p>CMP-Neu5Ac sodium salt (CMP-sialic acid) is a compound of the monosaccharide N-acetylneuraminic acid (Neu5Ac) O-linked with the nucleotide cytidine-5’-monophosphate (CMP). CMP-sialic acid is a substrate for sialyltransferases, which attach sialic acid to a growing oligosaccharide chain. This sugar nucleotide is produced in cytoplasm and then transported into Golgi lumen by a nucleotide-sugar transporter, where it is used in sialylation reactions on glycoproteins and glycolipids.</p>
