Definition of the noun chitin

What does chitin mean as a name of something?

noun - plural: chitins

  1. a tough semitransparent horny substance; the principal component of the exoskeletons of arthropods and the cell walls of certain fungi
    • example: Chitin is a polysaccharide.
    • lexical domain: Substances - nouns denoting substances
    • more generic words: polyose / polysaccharide = any of a class of carbohydrates whose molecules contain chains of monosaccharide molecules
    • substance: glucosamine = an amino derivative of glucose that is a component of many polysaccharides

Alternative definition of the noun chitin


  1. [carbohydrates] A complex polysaccharide, a polymer of N-acetylglucosamine, found in the exoskeletons of arthropods and in the cell walls of fungi; thought to be responsible for some forms of asthma in humans.

    • also known as "Chitin: fulfilling a biomaterials promise"


Chitin ₙ is a long-chain polymer of a N-acetylglucosamine, a derivative of glucose, and is found in many places throughout the natural world. It is a characteristic component of the cell walls of fungi, the exoskeletons of arthropods such as crustaceans and insects, the radulae of molluscs, and the beaks and internal shells of cephalopods, including squid and octopuses. The structure of chitin is comparable to the polysaccharide cellulose, forming crystalline nanofibrils or whiskers. In terms of function, it may be compared to the protein keratin. Chitin has also proven useful for several medical and industrial purposes. In butterfly wing scales, chitin is often organized into stacks of nano-layers or nano-sticks made of chitin nanocrystals that produce various iridescent colors by thin-film interference: similar, analogous structures made of keratin are found in iridescent bird plumage.
