N,N',N'',N''',N''''-Pentaacetylchitopentaose

Penta-N-acetylchitopentaose is a specific oligosaccharide composed of five N-acetylglucosamine units linked by a β-(1,4)-glycosidic bond. It is a key structural fragment of chitin, the second most abundant polysaccharide on Earth, found in the exoskeletons of arthropods and the cell walls of fungi. This compound is used in research to study the structure of chitin and the activity of chitinases.
