What is the difference between chitin and cellulose?
Just so, why is chitin stronger than cellulose?
Chitin. 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.
Also, what is chitin and what is its function? Although chitin is the dominant constituent, other compounds such as proteins and calcium carbonate also play a crucial role in the formation of exoskeleton. The main function of this chitin-containing exoskeleton is to keep the inner soft tissue safe from any sort of injury.
Similarly, you may ask, is chitin a Homopolysaccharide?
Chitin is a homopolysaccharide. This just means that it is made up of repeating units of the same monosaccharide - in this case that monosaccharide is N-acetylglucosamine. Other examples of homopolysaccharides are glycogen and cellulose.
What is the major difference between chitin and other types of polysaccharides?
Cellulose and chitin are both structural polysaccharides that consist of many thousand glucose monomers combined in long fibers. The only difference between the two polysaccharides are the side-chains attached to the carbon rings of the monosaccharides.
