chitin(redirected from chitinoid)
Also found in: Dictionary, Thesaurus, Encyclopedia.
a horny polysaccharide, the principal constituent of shells of arthropods and shards of beetles, and found in certain fungi.
A linear polymer of N-acetyl-d-glucosamine, linked β(1→4), similar in structure to cellulose; the second most abundant polysaccharide in nature, comprising the horny substance in the exoskeleton of beetles, crabs, and certain microorganisms, as well as in some plants and fungi.
chitin/chi·tin/ (ki´tin) an insoluble, linear polysaccharide forming the principal constituent of arthropod exoskeletons and found in some plants, particularly fungi.
A nitrogen-containing polysaccharide that is a tough, protective, semitransparent substance and is the principal component of arthropod exoskeletons and the cell walls of certain fungi.
A polymer of N-acetyl-d-glucosamine similar in structure to cellulose and the second most abundant polysaccharide in nature, comprising the horny substance in the exoskeleton of beetles, crabs, certain microorganisms, and other life forms.
chitinA carbohydrate polymer (polysaccharide) found in worms, insects, crustaceans and fungi but not in mammals. Mammalian chitinases, however, exist and one has been implicated in allergic ASTHMA. Neutralization of this enzyme reduces airway inflammation and hyper-responsiveness.
chitina linear POLYSACCHARIDE containing β(1---->4)-linked N -acetylglucosamine units, that has considerable strength because of its long fibrous molecules. It is resistant to chemicals and is found in the cuticle of insects and some other arthropods where the outer parts are impregnated with tanned proteins which gives it added strength. It is also found in the cell walls of most FUNGI, in certain DIATOMS and certain protozoa.
a horny polysaccharide of N-acetylglucosamine, the principal constituent of shells of arthropods and shards of beetles, and found in certain fungi.
chitin synthase inhibitors
used as antifungals and for control of flea infestation. See also lufenuron.
