<p>The ‘tallowate’ esters are probably the best known derivatives of sucrose and many attempts have been made to commercialise them in order to exploit their excellent surfactant functionalities.  The most functional products are the mono- and diesters of the tallow acids (stearic, palmitic, oleic) with hydrophile-lipophile balance (HLB) values that lend themselves to surfactant applications in foods and cosmetics.  They also have other uses, for example in coating fruits with a semipermeable membrane that acts as a preservative.  Manufacturing economics have prevented these products from mass production and they remain in niche applications.</p>

<p>4-Aminobutyl 3-O-(a-D-mannopyranosyl)-a-D-mannopyranoside is a fluorescent, water soluble, and hydrophilic glycoside. This compound is synthesized through the condensation of 4-aminobutyric acid with 3-(2,3,4,6-tetraacetyl glucosamine) to form an aminobutyl ester. The aminobutyl ester is then reacted with a D-mannose derived from 2,3,4,6-tetraacetyl glucosamine. This product is used in glycoprotein analysis and can be modified for various purposes.</p>

<p>2,3,6,2',3',4',6'-Hepta-O-acetyl-b-lactosyl azide is a custom synthesis of a carbohydrate that has been modified by the addition of acetyl groups to one end and the attachment of an azide group to the other. The synthesis of this compound has been completed in high purity and is available for purchase. This compound is a complex carbohydrate that is a sugar that can be modified by fluorination. It is also an oligosaccharide or polysaccharide with saccharide units.</p>

<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>Zymosan is prepared from the cell walls of baker's yeast (Saccharomyces cerevisiae) and consists of polysaccharide chains of various molecular weights, containing approximately 73% polysaccharide, 15% protein, 7% lipid and other inorganic components. When injected into animals, it induces inflammation and has been used for many years in inflammation and immunology research. The conditions activated include components of the complement system, prostaglandins and leukotrienes, platelet aggregation factor, and lysosomal enzymes. Zymosan preparations are often insoluble but can be made soluble for separation on DE cellulose or Sepharose to produce more active fractions.</p>

<p>Chitopentaose is a pentaacetyl derivative of the sugar chitohexaose. It is an oligosaccharide that has been shown to inhibit the activity of glycosidases and lectins, which may be due to its high affinity to these enzymes. Chitopentaose has also been found to bind to insulin receptors in the human tumor cell line A-20, leading to a reduction in tumor growth. The molecule also inhibits the transcriptional regulation of genes encoding for penicillin-binding protein, mouse tumor necrosis factor, and α1-acid glycoprotein.</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.

<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>
