Category

Polymers

Synonyms

(1,4)-N-acetyl-D-glucos-2-amine

Description

The monomers are identified as N-Acetyl-Amnioglucose. Chitin is a polysaccharide containing nitrogen in which monomers occur with the glycosidically linked components beta 1,4. It is the same coupling as glucose with cellulose, however in chitin the hydroxyl group of the monomer is replaced with an acetyl amine group. The resulting, stronger hydrogen bond between the bordering polymers makes chitin harder and more stabile than cellulose.
