Chitin distribution (1) arthropod mainly crustaceans, such as shrimp, crab, etc., contain chitin up to 58% to 85%; followed Insecta (such as locusts, butterflies, mosquitoes, flies, silkworm pupae containing shells and other crustaceans Su 20% to 60%), Myriapoda (such as millipedes, centipedes, etc.), arachnids (such as spiders, scorpions, ticks, mites and other wholesale chitin, chitin content of 4% to 22%); (2) molluscs including dual nerve classes (such as chitons), gastropods (such as abalone, snails), Tusk shell (eg angle shellfish), Lamellibranchia (such as oysters), cephalopods (such as squid, parrot) etc., chitin content of 3% to 26%; (3) including the original ring worm annelid classes (such as insect nest angle), hairy feet Gang (such as Nereis, earthworms) and Hirudinea (such as leeches) three bonds, Some contain chitin little, while others are as high as 20% to 38%; chitin joint distribution of other animals, hoof, foot chitin hard part, as well as animal muscle and bone joints are chitin exist. In addition chitin market, also found in plants oligomeric chitin or chitosan, one case of plant cell walls by pathogen attack, some degradation of the cell wall polysaccharides of biologically active oligosaccharides, wherein it crustacean chitin six sugar factory, a typical example is the trunk after injury, wound healing in which the crustaceans found at hexasaccharide; Another case is lipooligosaccharide Rhizobium produced, but also crustaceans tetrasaccharide, pentasaccharide and crustacean carapace six sugar.
