Chitin

Catalog Number
ACM1398614
CAS Number
1398-61-4
Product Name
Chitin
Structure
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.
