<p>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.</p>

<p>Found in glycoproteins including ovalbumin and human immunoglobulin M</p>

<p>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. Neoagarodecaose is reported to have potential for novel cosmeceuticals.</p>

<p>3'-(N-Glycolyl-a-neuraminosyl)lactose is a carbohydrate that is synthesized from lactose, which is a disaccharide composed of glucose and galactose. It is synthesized by the modification of the terminal hydroxyl group on the galactose moiety with glycolyl chloride. 3'-(N-Glycolyl-a-neuraminosyl)lactose has been shown to inhibit the growth of bacteria and fungi. It also has the potential to be used as an anti-cancer drug candidate due to its ability to inhibit protein synthesis in cells. This carbohydrate can also be modified by methylation, glycosylation, or click chemistry.</p>

<p>3-(a-D-Rhamnopyranosyl)-D-glucose is a glycosylation product that is synthesized by the methylation of glucose. It is a complex carbohydrate with a high purity, CAS number and custom synthesis. 3-(a-D-Rhamnopyranosyl)-D-glucose has been modified by fluorination and click chemistry to produce a versatile reagent for glycosylation reactions.</p>

<p>Useful oligosaccharide-lipid conjugate for raising antibodies.</p>

<p>GD1a (shown as sodium salt) is one of the major gangliosides in neuronal and glial membranes. It has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with sialic acids linked α2,3/α2,8 to the inner galactose residue, α2,3 to the outer galactose residue and ceramide linked β to position 1 on the reducing terminal glucose residue (Ledeen, 2009). It interacts with myelin-associated glycoprotein (MAG) and is essential for long-term axon-myelin stability. It plays a role in viral infection as it is a receptor for viral glycoproteins in rotavirus and paramyxovirus 1. The hexasaccharide GD1a moiety was also found on a glycoprotein that acts as a receptor for adenovirus type 37. GD1a ganglioside also interacts with botulinum neurotoxin and is crucial for its entry into cells (Kolter, 2012).</p>

<p>Lactose 6'-sulfate is a custom synthesis of a complex carbohydrate and an oligosaccharide. It is modified by methylation and glycosylation, which can be altered to create other saccharides such as galactose. Lactose 6'-sulfate has been fluorinated in the alpha position and contains a sulfate group that is attached with a click chemistry reaction. Lactose 6'-sulfate has CAS number 1015758-24-3 and is high purity.</p>

<p>3-O-(2-Acetamido-2-deoxy-b-D-galactopyranosyl)-D-galactopyranose is a sugar molecule with biological properties such as lectin, terminal sugar, and carbohydrate. It is a specific sugar for the blood group B. This sugar is also used in assays for pneumococcus, which is a bacterium that can cause pneumonia. 3-O-(2-Acetamido-2-deoxy-b-D-galactopyranosyl)-D-galactopyranose is oxidized by enzymes called oxidases to form 3,4,6 -triacetamido galactose (3TAG) and 3,4,6 -triacetamido glucose (3TG). The disaccharide residues are then hydrolyzed into monosaccharides by glycoconjugates and polyvalent glycosidases.</p>

<p>Synthesized by the action of zinc chloride on tetra-O-acetylmannose and 1-chloro-3,4,6- tri-0-acetylmannose.  Isolated from partial acetolysates of baker's yeast mannan and Saccharomyces rouxii mannan.</p>
