    Chitin (C 8 H 13 O 5 N) n (/ ˈ k aɪ t ɪ n / KY-tin) is a long-chain polymer of N-acetylglucosamine, an amide derivative of glucose. Chitin is the second most abundant polysaccharide in nature (behind only cellulose); an estimated 1 billion tons of chitin are produced each year in the biosphere. [1]

  3. Chitin is a large, structural polysaccharide made from chains of modified glucose. Chitin is found in the exoskeletons of insects, the cell walls of fungi, and certain hard structures in invertebrates and fish. In terms of abundance, chitin is second to only cellulose.

    Chitin chemistry and crystal structure. Chitin is a polysaccharide composed of 1–4 linked 2-acetamido-2-deoxy-β- d -glucopyranose, figure 2. On the evolutionary map, it is safe to say chitin is placed between cellulose and collagen.

  7. Chitin, white, horny substance found in the outer skeleton of insects, crabs, and lobsters and in the internal structures of other invertebrates. It is a polysaccharide consisting of units of the amino sugar glucosamine. As a by-product of crustacean processing, chitin is used as a flocculating.

    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 poly[~-(1~4)-2-acetamido-2-deoxy-D-glucopyranose] and its idealised structure (1.1) is shown in Figure 1.1, from which it can be seen that it is structurally similar to cellulose (1.2) except that the C(2)-hydroxyl group of cellulose is replaced by an acetamido group.

    Chitin, the second most abundant natural polysaccharide, after cellulose, is a linear polymer composed of repeating β (1,4)-N -acetylglucosamine units (Figure 18). Chitin exists in the shells of arthropods such as crabs, shrimps, and insects and is also produced by fungi and bacteria.
