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.
