Chitin: Structure, Function, and Uses
One of the most important benefits of chitin is its use in making fertilizers. Chitin-containing fertilizers are organic, non-toxic, and have shown to increase crop productivity. Chitin in fertilizers helps in increasing soil organisms and enzyme activities, which positively affects soil health. This in turn increases crop yield.
Chitin
Chitin (poly-N-acetyl-glucosamine) is one of the most common polymers found in nature. Structurally, it is related to cellulose, which consists of long chains of glucose molecules linked to each other. In chitin, the building block of the chains is a slightly modified form of glucose. ... Chitin is present in the shells of all crustaceans and ...

3.5: Carbohydrates
Complex carbohydrates, or polysaccharides, consist of hundreds or even thousands of monosaccharides. They include starch, glycogen, cellulose, and chitin. They generally either store energy or form structures, such as cell walls, in living things. Starch is a complex carbohydrate that is made by plants to store energy.
