Chitin exists in nature in the lower plants fungi, algae cells chitin sale, crustaceans shrimp, crabs, insects, housing, higher plant cell walls, etc., in an amount not less than the cellulose-rich chitin, is In addition to the polysaccharide cellulose is another important category. It is estimated that in nature, the annual amount of chitin biosynthesis of up to 100 billion tons. Chitin is the application from crab, shrimp in genetic engineering of animals to extract cellulose polymer chitin specifications, is the reputation of the scientific community as "sixth element of life" and therefore the government has been identified in Europe and America for functional immune substances. In the fungus, Cordyceps and other plants also contain trace "chitosan", but the content is only between 2% -7%. Chitin is positive dietary fiber in the universe only positively charged. Amino group-containing, multi-linear polysaccharide polymerization of N- acetyl -D- glucosamine-pyran is made of chitin extracted from shrimp, crabs and other crustaceans, the shrimp, crab shell main organic component, also known as of chitin, chitin.
