- Cellulose
The cells of a plant are surrounded by a thick protective layer called the cell wall. Cellulose is a major component of this protective layer. Cellulose is a polysaccharide, a polymer of glucose, (carbohydrate) and it is the most abundant macromolecule...

chitin
Term: chitin
Literally meaning: ?pertaining to tunic?
Origin: Anc Greek
?????/chiton(=tunic or gown usually worn next to the skin)
Coined/History
Chitin was first isolated from mushrooms in 1811 by plant chemist Henry Braconnot (1781-1855) who originally termed it as ?fungine?. Later on, in 1823, Augustus Odier isolated the same substance from the cuticles of beetles and named it ?chitin? from Greek word chiton.
Definition
Chitin(C8H13O5N)n is a polymer (long-chain molecule) of monosaccharide N-acetylglusamine. It is found mainly as the main component of the cell wall of fungi and the exoskeletons of arthropods. In contrast to cellulose, which is obtained from terrestrial sources, such as wood, chitin is regarded as an abundant marine biopolymer.
