<p>Cellooctaose is a synthetic, water-soluble oligosaccharide with a molecular weight of 1,000 daltons. It is produced by the reaction of propionate and intramolecular hydrogen with a water molecule to form glycosidic bonds. Cellooctaose can be used as a coating for pharmaceutical tablets and capsules to prevent dissolution in gastric acid. Cellooctaose is homologous to cellulose and has been used in recombinant protein production for the purpose of modifying viscosity. Cellooctaose has also been shown to inhibit the growth of cancer cells via lysosomal membrane permeability enhancement. This may be due to its ability to bind to fatty acids on the surface of cancer cells, which then leads to increased cell death.</p>

<p>Blood group B trisacchharide-APE-HSA is a synthetic carbohydrate that inhibits the synthesis of complex carbohydrates. The methylation of saccharides and polysaccharides can be accomplished by the addition of an amine to the 3′ hydroxyl group. In this reaction, the sugar is attached to a protein carrier (e.g., human serum albumin) via an amide bond, which prevents its degradation by proteases in the body. The modification of saccharides and polysaccharides is also accomplished through click chemistry, which is based on copper catalysis. This process involves attaching two functional groups through a copper-mediated reaction, forming a new carbon-carbon bond. Modification of saccharides and oligosaccharides can be accomplished using either chemical or enzymatic methods.
