A compound or molecule that is composed of carbon, oxygen and hydrogen in the ratio of 2H:1C:1O. Carbohydrates can be simple sugar s such as sucrose and fructose or complex polysaccharide polymer s such as chitin .

2. Cell wall
Structure produced by some cells outside their cell membrane; variously composed of chitin , peptidoglycan, or cellulose.

3. Chitin

4. Chitin
A polysaccharide contained in fungi ; also forms part of the hard outer covering of insects.

5. Chitinase
An enzyme which breaks down chitin , which is a polysaccharide that forms the hard outer shell of arthropods (insects, spiders, crustaceans, etc.), and the cell walls of fungi , and some algae .

6. Chitinolytic
Having to do with an enzyme which converts chitin , a polysaccharide that forms the hard, outer shell of arthropods (insects, spiders, crustaceas, etc.) and the cell walls of fungi and some algae , into chitobiose , which is a disaccharide secreted by such things as spiders and some plants.

7. Sclerite

8. Trilobites
A group of benthonic, detritus-feeding, extinct marine invertebrate animals (phylum Arthropoda), having skeletons of an organic compound called chitin . Trilobites appear in abundance early in the Cambrian period and were dominant animals in the Burgess Shale fauna, before finally becoming extinct at the end of the Permian period.

9. Zygomycetes
A class of fungi that usually has a coenocytic mycelium with chitinous cell walls. Sexual reproduction normally involves the formation of zygospores.The group lacks motile spores.
