chitin
(Science: cell biology) a cross linked polymer of N acetyl D glucosamine that is the major structural component of arthropod exoskeletons and fungal cell walls. Widely distributed in plants and fungi.
Chitinous layer
[Gr. chiton - an outer covering, tunic]. A thick, clear layer of an Ascaris egg shell which is composed of chitin and protein and provides a protective coating located between the fertilization membrane and the ascaroside layer.
chitin -- n. A carbohydrate polymer found in the cell walls of fungi and in the exoskeletons of arthropods, which provides strength for support and protection; chitinous- adj.
Chitin Inhibitors
These substances, diflubenzuron (Dimilin®) is an example, interfere with the synthesis of chitin, the material that makes up the insect exoskeleton [see structure].
chitin A polysaccharide contained in fungi; also forms part of the hard outer covering of insects.
chlamydia A sexually transmitted disease caused by a parasitic bacterium that lives inside cells of the reproductive tract.
chitin
(ky-tin) [Gk. chiton, a tunic, undergarment]
A structural polysaccharide of an amino sugar found in many fungi and in the exoskeletons of all arthropods.

chitin - the horny outer coating of an insect formed by cells that secrete a semi-liquid substance which solidifies on exposure to air. It is a high molecular weight polymer of N-acetyl glucosamine linked by 1,4-$-glycosidic bonds.
chitin
A structural polysaccharide of an amino sugar found in many fungi and in the exoskeletons of all Arthropods.
Chitin is also a homopolymer but is made of repeating subunits of N-acetyl-glucosamine, a derivative of glucose which has an amino group (containing nitrogen).
chitin 1.The polysaccharide found in the exoskeleton of arthropods.2. High molecular weight polymer of N-acetyl glucosamine linked by 1,4-b-glycosidic bonds.
a chitin layer (polymer consisting mainly of unbranched chains of N-acetyl-D-glucosamine)
a layer of β-1,3-glucan
a layer of mannoproteins (mannose-containing glycoproteins) which are heavily glycosylated at the outside of the cell.
Setules. Chitinous projections from copepod maxillipeds that trap food particles
Shelf-slope break. Line marking a change from the gently inclined continental shelf to the much steeper depth gradient of the continental slope ...
Cellulose and Chitin are polysaccharides that function to support and protect the organism. The cell walls of plants are composed of cellulose. The cell walls of fungi and the exoskeleton of arthropods are composed of chitin.
A hard exoskeleton, a strong but flexible outer covering composed primarily of the carbohydrate chitin. This functions in protection, attachment for muscles, locomotion, and prevention of desiccation.
Presence of jointed appendages.
While they may all have chitin, a shell created by the epidermis, crustaceans have an extra layer that is calcified. That calcification makes it much sturdier and much heavier. Arthropods also have very advanced sense organs.
It's made up of chitin. All vibrios, including Vibrio cholerae, have a very powerful chitinase, an enzyme that breaks down that shell structure, so it plays a role in nature.
Eucaryotic, chemoheterothropic microorganisms with cell walls containing chitin, cellulose or both. They may be unicelluar or multicellular. Often the terms yeast and mould are used to describe the morphological appearance of them.
Crustacean: Any of a zoological class (Crustacea) that have a chitinous and/or calcareous exoskeleton (lobsters, shrimps, crabs).
Oligosaccharides are found as common form of protein posttranslational modification. Polysaccharides represent an important class of biological polymer. Examples include starch, cellulose and chitin.
