Oligosaccharides

Ganglioside GM3 (sodium salt) has a core disaccharide structure (Galβ1,4Glc) with sialic acid linked α2,3 to the galactose residue and ceramide linked β to position 1 on the reducing terminal glucose residue (Ledeen, 2009). Ganglioside GM3 is strongly associated with human tumors, such as: lung, brain and melanomas, where it is over expressed. It is seen as a possible tumor-associated carbohydrate antigen for cancer immunotherapy (Changping, 2019). GM3 ganglioside is implicated in various other diseases involving chronic inflammation, such as: insulin resistance, leptin resistance, T-cell function and immune disorders (e.g., allergic asthma). It has also been shown to play an essential role in murine and human auditory systems, and a common pathological feature of GM3S deficiency is deafness (Inokuchi, 2018).

Isolated from ivory-nut mannan hydrolysates

Sucrose is a sugar that is used as a food additive. It is the disaccharide of glucose and fructose, which are two monosaccharides. Sucrose can be synthesized by the glycosylation of glucose and fructose in an α-1,2 linkage. Sucrose can also be synthesized by the fluorination of sucrose followed by methylation with methylamine. The synthesis of sucrose starts with the reaction of acrylonitrile with formaldehyde to produce acrylonitrile trimer, which is then reacted with methanol to produce methyl 3-hydroxybutyrate. This product undergoes a series of reactions to form sucrose.

Benzyl 2-acetamido-2-deoxy-3-O-(b-D-galactopyranosyl)-a-D-glucopyranoside is a synthetic substrate that is used in the synthesis of disaccharides. It is catalytic and has an efficient method for the preparation of acetonitrile, which can be eluted with acetic acid. It is a reagent that reacts with halides to form equimolar acetates. Acetylated benzyl 2-acetamido-2 deoxy 3 O-(b D galactopyranosyl) a D glucopyranoside can be obtained by reacting benzyl 2 acetamido 2 deoxy 3 O-(b D galactopyranosyl) a D glucopyranoside with acetic anhydride.

Produced by the reverse hydrolysis of a mannose substrate.  Isolated from the partial hydrolysates of bakers' yeast (Saccharomyces cerevisiae) mannan.  This disaccharide also forms the sugar portion of the phospholipid, phosphatidylinositodimannoside, of Mycobacterium tuberculosis.

Stachyose hydrate is a methylated, custom-synthesized, click-modified oligosaccharide that is used as a synthetic complex carbohydrate. It is synthesized from the saccharide stachyose by fluorination and modification with methyl groups. This product may be used in biological research or as a fluoropolymer precursor. Stachyose hydrate has been shown to have high purity and can be modified to contain monosaccharides and sugars.

4-Methoxyphenyl 4-O-(4-O-acetyl-3,6-di-O-benzyl-2-deoxy-2-phthalimido-b-D-glucopyranosyl)-3,6-di-O-benzyl -2,4,6-(1',4'-dioxan)-tris(2,3,5',6'-tetraethoxy)phenol

3-O-(b-D-Galactopyranosyl)-D-arabinose is a disaccharide sugar that is found in mammalian tissue and many other biological systems. It binds to fatty acids, which are important for the structure of cell membranes. 3-O-(b-D-Galactopyranosyl)-D-arabinose is also an important component of oligosaccharides and glycolipids. The binding constants for this sugar have been determined by both titration calorimetry and microcalorimetry. 3-O-(b-D-Galactopyranosyl)-D arabinose has been used as an antiviral agent against Leishmania spp., which is a parasitic protozoa that causes leishmaniasis, the third most common human parasitic disease. This compound has also been shown to inhibit the growth of microalgae, such as Chlorella sorokiniana.

Lactobionic acid is produced by oxidation of lactose. It is widely used in the food and in pharmaceutical field, due to its excellent biocompatibility, biodegradability, nontoxicity, chelating, amphiphilic and antioxidant properties.  Lactobionic acid is produced as a white solid powder, freely soluble in water and slightly soluble in anhydrous ethanol and methanol.

This is a synthetic, high purity and custom-synthesized carbohydrate. The chemical name is 1,2,3,6-Tetra-O-acetyl-4-O-(2,3,4,6-tetra-O-acetyl-b-D-galactopyranosyl)-b-D-thioglucopyranose. It has been modified with the Click reaction to allow for chemical modification. This product is a complex carbohydrate that has been fluorinated to create an organic fluorine compound.

Trehalose-6-phosphate dipotassium salt is a natural sugar that is found in plants, animals, and fungi. It functions as a carbohydrate reserve and protects cells against osmotic stress. Trehalose-6-phosphate dipotassium salt can be synthesized by the enzyme trehalase from the sugar trehalose and 6-phosphate. It has been shown to protect cells from weevil infestation, which may be due to its ability to produce abiotic or biotic stress. Trehalose-6-phosphate dipotassium salt can be purified using hydrophilic interaction chromatography on an on-line system.

Agarose is a polysaccharide found in red algae, typically Gelidium and Gracilaria. It is a strictly alternating polysaccharide of α-1,3 linked D-galactose and β-1,4 linked L-3,6 anhydrogalactose with occasional sulfation at position 6 of the anhydrogalactose residue. Agaro-oligosaccharides result from cleavage at galactose residues and neoagaro-oligosaccharides from cleavage at 3,6-anhydro residues. Neoagarohexaose is reported to have potential for novel cosmeceuticals.
