a polymer of repeating sugar molecules (a slightly modified glucose, N-acetylglucosamine). See image. Chitin is also frequently found in a cross-linked form, alpha chitin, as in the armor of arthropods. See image. Chitin is the material which makes up the exoskeleton of insects and, in more or less modified form, in almost all arthropods. Significantly, it is also found in the radular "teeth" of mollusks, the setae (bristles) and jaws of annelid worms, and the cell walls of Fungi. So, this is exceedingly ancient stuff, possibly predating the split between bacteria and metazoans.

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.

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.

The dense substance forming the indigestible outer skeleton of insects, and the material from which the walls of the mycelia are made.

A tough, horny polysaccharide that forms part of the hard outer integument in insects.

Complex polysaccharide (sugar) used by arthropods to construct their external skeletons.

A complex carbohydrate that gives shape and strength to the external skeleton of arthropods, including insects, spiders, and crustaceans.

a colourless polysaccharide that serves as the major fibrous component of the insect cuticle or integument.

A horny substance, forming all or part of the skeleton of arthropods.

a tough semitransparent horny substance; the principal component of the exoskeletons of arthropods and the cell walls of certain fungi

hard substance making up the struts of wings in faerie dragons, and also a component of the arthropod exoskeleton.

A polysaccharide that is the principal component of the exoskeleton of arthropods and of the bodies of fungi.

A polysaccharide composed of N-acetyl glucosamine subunits. Chitin is found in the cuticle of insects and some other arthropods. It is also found in the cell walls of fungi. chlorophyll: The green pigment found in all plant and algae cells, and in many bacteria, which serves as the receptor of light energy prior to its conversion to chemical energy during photosynthesis.

A tough but flexible organic material used by many organisms for parts of their skeletons. Insects, for example, have skeletons largely made up of chitin. Among cephalopods chitin is used extensively, for example the beaks and daws of living species are chitinous.

Structural organic substance similar to cellulose, found in shellfish and insect dermal sheaths and the membrane of some mushrooms. Back

A structural polysaccharide of an amino sugar found in many fungi and in the exoskeletons of all Arthropods.

Polysaccharide that makes up the exoskeleton of an arthropod Class Level of scientific classification; below Phylum and above Order

One of the materials that makes up the exoskeleton of the crabs.

a water-soluble polysaccharide polymer composed of N-acetyl-D-glucosamine found in algae, arthropod and crustacean exoskeletons, fungal cell walls, and most protozoa.

A complex molecule found in the skin of insects and other arthropods which is composed of smaller units of nitrogen containing sugar

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

a polysaccharide, the principal constituent of shells of arthropods and shards of beetles, and found in certain fungi

a tough, protective, semitransparent substance, primarily a nitrogen-containing polysaccharide, forming the principal component of arthropod exoskeletons and the cell walls of certain fungi

The liquid produced by the insect's body which hardens to form the exoskeleton, the chrysalis, and the wing membrance

(noun, pronounced: KI-tin) - a tough, colorless material that makes up the insect exoskeleton.

a cross linked polymer that is the major structural component of fungal cell walls.

A polysaccharide found in the cell walls of fungi, insects, and other organisms such as tubes of Vestimentiferan worms.

A white or colorless, horny substance forming part of the hard outer covering of insects, crustaceans, and some other invertebrates.

A naturally occurring polymer found in the shells of crabs and lobsters. Contained in the product Sea-Klear, chitin acts as a coagulant and flocculent for oils, metals and organic materials.

(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.

a complex polysaccharide molecule found in walls of fungi and exoskeletons of shrimps and crabs

The tough horny material, it is a nitrogenous polysaccharide, which forms the exoskeleton of an insect.

a polymer of repeating sugar molecules (a slightly modified glucose, poly-N-acetyl--glucosamine). See image. Chitin is the material which makes up the exoskeleton of insects and, in more or less modified form, in almost all arthropods. In arthropods, chitin occurs in a crosslinked form, α-chitin. Significantly, it is also found in the radular "teeth" of molluscs, the setae (bristles) and jaws of annelid worms, and the cell walls of Fungi. So, this is exceedingly ancient stuff, possibly predating the split between bacteria and metazoans. [What may be of sociological interest is that the 1,5 aldose linkage was missing from the middle glucose in this diagram and no one spotted it for over a year ....

the tough material of which insect and crustacean exoskeletons are made

Substance produced by an insect which hardens and forms its exoskeleton.

A specialized polysaccharide containing nitrogen that occurs in the exoskeleton of insects and other arthropods. Chitin also makes up a large part of the cell walls in many fungi.

principle microfibrillar component of cell walls of fungi, composed of (1 - 4 ) linked polymer of N-acetyl-glucosamine. The compound is found in varying concentrations in nearly all fungi. It gives structural strength and shape to the cell and the microfibrills are usually located in the inner part of the wall.

Chitin is a tough, colorless nitrogenous polysaccharide that is a major component of the hard exoskeleton of insects (and other arthropods).

Chitin (C8H13O5)n is a long-chain polymeric polysaccharide of beta-glucose that forms a hard, semitransparent material found throughout the natural world. Chitin is the main component of the shells of crustaceans such as the crab, lobster, and shrimp, as well as the exoskeletons of insects like ants and beetles. It is even found in the cell walls of some fungi, molds, and yeast.
