1,2,3,4,6-Penta-O-acetyl-b-D-glucopyranose, also known as beta-D-glucose pentaacetate, has high chemical stability and long shelf life. This protected form of glucose is a key building block of any chemical synthesis of glucose-containing oligosaccharides or glycoconjugates. In the presence of Lewis acids it can be used as a glycosyl donor to make simple glycosides. In order to perform more complex glycosylations, it can be converted into more reactive donors, such as glycosyl halides or thioglycosides. Beta-D-glucose pentaacetate is also used as a food additive and flavouring agent.

2,5-Anhydro-3-deoxy-D-ribohexonic acid is a fluorinated monosaccharide. It is synthesized by the modification of 2,5-anhydro-3-deoxyglucose with N-(2'-fluoroethyl)trimethoxysilane (FETS). This synthetic compound can be used as a glycosylation or polysaccharide building block in the synthesis of complex carbohydrates. The FETS modification allows for the introduction of various functional groups on C1 and C2 while maintaining the high purity.

GDP-D-mannose is a natural mannosyl donor and substrate for mannosyltransferases that catalyses mannosylation, for instance during the synthesis of the trimannoside core of complex, high-mannose or hybrid N-glycans. GDP-D-mannose is widely used in (chemo)enzymatic synthesis of oligosaccharides and its biosynthesis occurs from glucose-6-phosphate over several steps. GDP-D-mannose consists of a D-mannose unit, α-glycosydically linked to the nucleotide guanosine diphosphate (GDP). Examples of this important reaction would be the transfer of mannosyl moieties onto the dolichol-P-P-GlcNAc2 precursor of N-glycans in the endoplasmatic reticulum, with release of GDP, or the mannosylation reactions during GPI-anchor (bio)synthesis. GDP-D-mannose has also been used for the in vitro synthesis of b-mannan oligosaccharides.

D-Mannosaminuronic acid is a monosaccharide that has been isolated from the seed of the African plant, Acacia drepanolobium. It is found to be an antigenic component of shigella and related enterobacteria and plays an important role in the biosynthesis of glycolipids. D-Mannosaminuronic acid can be hydrolyzed by acidic enzymes such as lipases, esterases, phosphatases, or proteases. This process may lead to the liberation of fatty acids and sugars. The purified enzyme preparations have been shown to catalyze the synthesis of D-mannosaminuronic acid from mannose and fructose.

The chemical formula for this compound is C20H28N4O14 and its molecular weight is 524.329 g/mol. 2A2D3BTSL has been fluorinated, glycosylated, and methylated. It is an oligosaccharide with 6 monosaccharides and a complex carbohydrate that has a saccharide in the center of it.

3-Deoxy-D-gluconic acid is a chemical compound that has the chemical structure of C6H12O6. It is a white crystalline solid that can be found in nature as a reaction product of glucose and oxygen. 3-Deoxy-D-gluconic acid can also be synthesized by reacting D-glucose with nitrous acid or sulfur dioxide. 3-Deoxy-D-gluconic acid is an organic acid and has been shown to inhibit the growth of filamentous fungi by acting on their glycosidic bonds. This chemical compound has not been shown to have any adverse health effects in humans, although it may cause irritation if it comes into contact with skin or eyes.

2,3:5,6-Di-O-isopropylidene-D-talose is a custom synthesis of methylated oligosaccharides. It is a complex carbohydrate that contains both a monosaccharide and a polysaccharide. 2,3:5,6-Di-O-isopropylidene-D-talose is a modification of the sugar D(+)-talose (a pentasaccharide), which has been fluorinated to make it more stable. This product has high purity, and can be used in many different applications such as click chemistry, oligosaccharide synthesis, or fluorination reactions.
2,3:5,6-Di-O-isopropylidene-D-talose is an Oligosaccharide that is a Polysaccharide. It can be used as an inhibitor for DNA polymerase α and β enzymes in PCR reactions

Ribulose 5-phosphate sodium is a chemical that can be used to inhibit the enzyme ribulose phosphate reductase. Ribulose 5-phosphate sodium has been shown to inhibit glycolaldehyde production in the chloroplasts of plants, effectively reducing the amount of carbon dioxide produced. This chemical has also been shown to have an inhibitory effect on other enzymes involved in carbon fixation and assimilation. The effectiveness of this chemical is dependent on the specific plant species and environmental conditions.

Chondroitin disaccharide 6S sodium salt is a synthetic, fluorinated, oligosaccharide that has been custom synthesized and glycosylated. It is a sugar-based compound with a high purity and excellent solubility in water. It was synthesized by click modification of the sugar monomer with an amine group at the reducing end. The chondroitin disaccharide 6S sodium salt was further modified with methylation to yield a product with a higher purity.
