Chitin is a polysaccharide found in the outer skeleton of insects, crabs, shrimps, and lobsters and in the internal structures of other invertebrates. Chitin is composed of (1-4) linked units of the amino sugar N-acetyl-glucosamine, and is the main source of production of chitosan, which is used in a number of applications, such as a flocculating agent, a wound healing agent, a sizing and strengthening agent for paper, and a delivery vehicle for pharmaceuticals and genes.

Chitin is the second most abundant polysaccharide in nature (after
cellulose). Chitin mainly consists of the amino sugar N-acetylglucosamine,
which is partially deacetylated. Chitin is a renewable resource and is
isolated from crain nab and shrimp waste. It is used for waste water
clearing, for cosmetics and for medical and veterinary applications.

Chitin is natural, non-toxic, non-allergenic, anti-microbial, and biodegradable. It has a strong positive charge, which allows it to bind with negatively charged surfaces or materials, including metals, skin, and macromolecules such as proteins. Medical Application: Early on it was found that chitin had wound-healing properties. By the mid-1950s, chitin-coated sutures were being used, which enhanced healing time by 35 to 50%. In the 1970s, researchers with the University of Delaware Sea Grant College Program developed a method to spin pure chitin filaments. These new chitin sutures could be absorbed by the body, eliminating the need for surgical removal. A Japanese firm bought the patent rights, and suture materials are now manufactured in Japan. In addition, this firm uses chitin to make dressings for burns, surface wounds, and skin-graft donor sites, which dramatically accelerate healing and reduce pain compared to standard treatments where the dressings must be removed.

Chitin-Coated SuturesOther medical uses for chitin include anti-bacterial sponges and hospital dressings, artificial blood vessels, contact lenses, tumor inhibition, dental plaque inhibition, and blood cholesterol control. Household products include sponges, diapers, feminine napkins, and tampons.

Water Treatment: Water Purification As a polymer, chitosan's natural tendency is to form long chains of molecules with positive charges, which act like hooks. These natural hooks catch organic materials, such as oils, detergents, and other contaminants suspended in water. The material then coagulates to form flakes that are easily filtered out. Filtration companies are using chitin in clarifiers to help filter particulates and chemicals from water.

Wastewater Treatment In Japan, chitosan was first used for wastewater treatment because of its metal-binding properties. It is also good for cleaning up toxic organic compounds, such as PCBs.

Chitin Dietary Supplements

Dietary Supplements: Chitosan has properties similar to plant fiber and can significantly bind fat, acting like a sponge in the digestive tract. It is not digestible itself and the bound fat leaves via the body without ever entering the bloodstream.

Cosmetics: Make-up powder; nail polish; moisturizers; face, hand, and body creams; and toothpaste are just a few consumer products that might contain chitin.

Agriculture: Seeds treated with chitosan are larger and stronger and more resistant to fungal diseases. Treating seeds with chitin can increase crop yields by up to 50%.

Chitin is added to commercial feed mixtures containing whey, a by-product of the cheese industry. Many animals find it hard to digest the high-lactose whey. But chitin supports the growth of beneficial microorganisms in the animals' digestive tract these bacteria produce enzymes that help the animals digest whey.
