Chitin (C8H13O5N) n, also known as chitin, chitin or chitosan, is a nitrogen-containing polysaccharides, for shrimp, crabs, insects, crustaceans and other important ingredients.
Chitin exoskeleton of the cell wall of fungi and arthropods in the main part of the number of other animals also contain this substance. Which is N- Acetyl -D- glucose amine polysaccharides, together with a β-1,4 mode (in a similar pattern of glucose units forming cellulose), actually chitin cellulose may be described as having a hydroxyl group the root of each monomer in an acetyl group to replace. This allows for increased hydrogen bonding between the polymer, the polymer to increase strength.
With its immutable form, chitin is translucent, pliable and elastic, and very tough. However, where it is often in the arthropod change, through hardened protein embedded in the substrate, forming a large part of the exoskeleton. Exoskeleton of insects are usually not replaced, but the larvae or crustaceans will be shedding because chitin shell composed not grow.
Chitin is one of the natural polymer。Through a microorganism such as bacteria secreted chitinase may accelerate the destruction of its structure, may be due to decomposition of chitin have receptors on simple sugars. If the chitin to be analyzed, through it will produce enzymes to break down the chitin monosaccharides and ammonia.
Chitin of cells without repulsion, the effect of the cells of the repair, and can slow the allergic skin. Chitin also contains moisturizing ingredients, it can also be an effective β-glucan moisturizing skin moisture.
