1,3,5-Tri-O-benzoyl-a-D-ribofuranose is a modified carbohydrate. It is synthesized by the methylation of 1,3,5-tri-O-benzoyl-a-D-arabinopyranose followed by glycosylation with 3,6-dideoxyhexose. This compound has been used as a substrate in enzymatic studies to investigate the modification of carbohydrates by glycosylation and methylation and can be used for the synthesis of other saccharides.

3-O-benzyl-diacetonide-d-glucose is a synthetic monosaccharide that can be used as a building block for oligosaccharides and polysaccharides. It is custom synthesized to meet your specific needs and can be modified with fluorination, methylation, or glycosylation. 3-O-benzyl-diacetonide-d-glucose has been shown to have high purity and is available in small quantities for custom synthesis.

1,5-Anhydro-2,3,4-tri-O-benzoyl-D-threo-pent-1-enitol is a high purity compound that is synthesized from D-threo pent 1 enitol. It is a sugar that belongs to the category of complex carbohydrates. This product can be custom synthesized and modified according to customer requirements.

Sorbitol, also known as glucitol, occurs widely in plants, such as, the fruits of the Sorbus and Crataegus spp.  Commercially it is produced by the catalytic hydrogenation of glucose (Collins, 2006).  Sorbitol is approved as a sugar substitute with the E number 420 and has ‘generally recognized as safe’ status (GRAS) from the US Food and Drug Administration. It is about 60% as sweet as sucrose and is a mild laxative.  Sorbitol has a wide range of other functional properties, including: humectancy, plasticizing ability, non-cariogenicity, and good chemical stability in harsh conditions, such as, alkaline pH and heat. Toothpaste production is the second largest application of sorbitol, accounting for 50,000 tons a year in Western Europe alone.  Other important uses of sorbitol as a humectant, include: formulation of cough syrups, multivitamin preparations, emulsions, and suspensions (O’Neil, 2013).

UDP-b-L-arabinopyranose is a nucleotide sugar that is used in the synthesis of proteins and other macromolecules. It is synthesized from uridine and d-ribulose 5-phosphate by the enzyme ribulokinase. The reaction between UDP, b-L-arabinofuranose, and ATP, catalyzed by arabinofuranosyl transferase, produces UDP-b-L-arabinopyranose. This nucleotide sugar can be converted to UDP-b-(1→4)-glucuronate by the enzyme glucuronosyltransferase. This process plays an important role in plant physiology as well as in cell wall biosynthesis. The optimal pH for this conversion is 7.5 to 8.2.

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.

Potent and specific inhibitor of α-mannosidase I. It is active against the Golgi isoform (GMI) of the enzyme and blocks carbohydrate branch elongation from immature to complex and hybrid N-glycans. Its anti-viral activity against HIV-1 is characterized by the alteration of N-glycan pattern and shift to high-mannose glycans on viral glycoprotein gp120, resulting in decreased infectivity of newly synthesized virions.

2,3,5-Tri-O-benzyl-b-D-ribofuranose is a synthetic monosaccharide that is used in the synthesis of complex carbohydrates such as glycosylation and polysaccharides. One use for this chemical is to modify the sugar moiety with methyl groups, yielding 2,3,5-tri-O-methyl b-D-ribofuranose. This modification helps prevent the sugar from being metabolized by enzymes in the body. The chemical can also be fluorinated to yield 2,3,5-trifluoro b-D-ribofuranose.

L-Mannonic acid-1,4-lactone is an acidic compound that has kinetic properties. It is used in the assays of chloride ions and neutral pH. L-Mannonic acid-1,4-lactone also has conjugates with hydrolytic activity and can be used as a synthetic intermediate for other organic compounds. L-Mannonic acid-1,4-lactone can be found in group P2 of the periodic table because it contains a hydroxyl group and an organic group with a methyl ethyl side chain. L-Mannonic acid-1,4-lactone hydrolyzes at high temperatures and may exhibit synergistic effects when combined with other agents. This product is also used to incubate cells such as k562 cells.

Phenyl-beta-D-thioglucuronic acid is a drug that is used to treat inflammatory diseases and autoimmune diseases. It is a basic structure that has been shown to have anti-estrogenic effects in vitro, although the mechanism of action is not well understood. Phenyl-beta-D-thioglucuronic acid can be crosslinked with proteins to form a matrix for wound healing. This drug has also been shown to be a potent inhibitor of proteases, and may inhibit other enzymes such as matrix metalloproteinases and serine proteases.

2,3,4-Tri-O-acetyl-a-D-xylopyranosyl bromide - Stabilised with 2.5% CaCO3 is a chiral compound that is a drug for the treatment of estrogen deficiency in postmenopausal women. It is synthesized from D-xylose and acetone by reductive elimination using an organotin catalyst. The resulting product has a nitro group at the 4 position and can be activated as a priming agent for DNA synthesis. This compound has been shown to be effective in treating intestinal disorders such as ulcerative colitis.
2,3,4-Tri-O-acetyl-a-D-xylopyranosyl bromide - Stabilised with 2.5% CaCO3 has been used to conjugate estrogens with various drugs to create new compounds that are more potent than free estrogens alone. Bioavailability of these conjugates has
