  1. a tough semitransparent horny substance; the principal component of the exoskeletons of arthropods and the cell walls of certain fungi
  2. (chitinous) of or resembling chitin
  3. Chitin (C8H13O5N)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 the main component of the cell walls of fungi, the exoskeletons of arthropods such as crustaceans (e.g. ...
  4. 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
  5. (chitinous) semitransparent horny substance composing shell
  6. (Chitins (Kiy-tinnz)) The nearly opaque, protective outer surface of insects (exoskeleton) created by nitrogen containing polysaccharides.
  7. A polysaccharide contained in fungi; also forms part of the hard outer covering of insects.
  8. A nitrogenous polysaccharide found in the exoskeleton of the tarantula.
  9. (kite - in) A protein material, similar to fingernails, that provides a protective covering for the horseshoe crab. The horseshoe crabís carapace is made of chitin.
  10. Compound secreted by the epidermis in arthropods and making up the bulk of their cuticle (outer layer of the body).
  11. A polysaccharide found in the cell walls of fungi, insects, and other organisms such as tubes of Vestimentiferan worms.
  12. A polysaccharide composed of amino sugar subunits. Chitin is the primary cell wall constituent in the Kingdom Fungi.
  13. The tough matter which forms the outer casing of the head, thorax, abdomen, legs, antennae etc of an insect.
  14. (silent h) – the substance forming the exoskeleton of insects, etc.
  15. Main component of the cell walls of arthropods, found in the outer skeleton of insects, crabs, and lobsters and in the internal structures of other invertebrates.
  16. A type of polysaccharide (sugar molecule) that is made by some plants and animals. The hard outer shell of shrimp, lobsters and many insects is made of chitin.
  17. A nitrogen-rich compounds found as a structural material in the exoskeletons of insects and in fungal hyphae
  18. Made up primarily of sugars often complexed with proteins, it is the principle component of a cuticle.
  19. A nitrogenous polysaccharide occurring as skeletal material in many invertebrates and fungi.
  20. The liquid produced by the insect's body which hardens to form the exoskeleton, the chrysalis, and the wing membrance
  21. A white or colorless, horny substance forming part of the hard outer covering of insects, crustaceans, and some other invertebrates.
  22. a structural polysaccharide that makes up the bulk of the scorpion cuticle.  Added to chitin are a variety of other substances, such as proteins (sclerotized and unsclerotized) and waxes which give special properties to the cuticle.
  23. The tough, insoluble polysaccharide making up a major part of the insect procuticle.
  24. (C8H13O5)n is a long-chain polymeric polysaccharides of beta-glucose that forms a hard, semitransparent material and found as a component of many arthropod exeskeletons.
  25. a tough, colourless ingredient which is the major component of the hard exoskeleton of insects including butterflies
