It is a cross linked polymer of N acetyl D glucos amine that is the major structural component of arthropod exoskeletons and fungal cell walls.
Chitin is a polysaccharide (polymer of sugar [saccharide],  monomers) that is found in the exoskeletons of arthropods (insects,  crabs, lobsters, shrimp), mollusks, and in t … he   beaks of cephalopods (squid and octopus). It is also found in the  cell walls of fungi. It is a structural polysaccharide found in the exoskeltons of arthropods (insects, crabs, lobsters, shrimp, etc.), mollusks (shelled organisms), beak of cephalopods (squid and … octopus), and in the cell walls of fungi. It is made up of saccharide monomers of N-acetylglucosamine, which is a derivative of glucose. In its pure, unmodified form, chitin is translucent, pliable, resilient, and quite tough. In most arthropods, however, it is often modified, occurring largely as a component of composite materials, such as in sclerotin, a tanned proteinaceous matrix, which forms much of the exoskeleton of insects. Structure of the chitin molecule, showing two of the N-acetylglucosamine units that repeat to form long chains in β-1,4 linkage. A close-up of the wing of a sap beetle; the wing is composed of chitin. What is chitin? It is a structural polysaccharide found in the exoskeltons of arthropods (insects, crabs, lobsters, shrimp, etc.), mollusks (shelled organisms), beak of cephalopods (squid and … octopus), and in the cell walls of fungi. It is made up of saccharide monomers of N-acetylglucosamine, which is a derivative of glucose. (2) A polysaccharide which makes up the cell walls of fungi and exoskeleton of insects. Supplement. Examples of organisms with chitin are the arthropods in their exoskeletons, some arachnids in their hard outer covering, molluscs in their radula, cephalopods in their beaks, and some fungi species in their cell walls. Chitin resembles keratin (protein component in human hair and nails) in structural function. It differs from keratin through its carbohydrate (polysaccharide) structural component. It is a structural polysaccharide found in the exoskeltons of arthropods (insects, crabs, lobsters, shrimp, etc.), mollusks (shelled organisms), beak of cephalopods (squid and octopus), and in the cell walls of fungi. It is made up of saccharide monomers of N-acetylglucosamine, which is a derivative of glucose. Chitin is a polysaccharide that makes up the cell walls of fungi  and the exoskeleton of insects. It creates a tough, protective  covering or a structural support. Edit. Share to: Answered.

Share to: Answered. chitin ous 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. chiton, a tunic, undergarment]. A structural polysaccharide of an amino sugar found in many fungi and in the exoskeleton s of all arthropods. chlorophyll ... ~ /KITE-in/ A structural polysaccharide that is the main component of the exoskeleton s of all arthropods and the cell wall s of fungi. Another feature of fungi is the presence of chitin in their cell walls. This is a long carbohydrate polymer that also occurs in the exoskeletons of insects, spiders, and other arthropods. The chitin adds rigidity and structural support to the thin cells of the fungus, and makes fresh mushrooms crisp.  chitin. (Science: cell biology) a cross linked polymer of N acetyl D glucos amine that is the major structural component of arthropod exoskeleton s and fungal cell wall s. Widely distributed in plant s and fungi. chiton, a tunic, undergarment]. A structural polysaccharide of an amino sugar found in many fungi and in the exoskeleton s of all arthropods. chlorophyll ... ~ /KITE-in/ A structural polysaccharide that is the main component of the exoskeleton s of all arthropods and the cell wall s of fungi. Chances are, you are sitting close to some chitin right now. Chitin is the main ingredient in the exoskeletons of arthropods and crustaceans and is also in the cell walls of fungi. That means everything from beetles, spiders, and butterflies to lobsters, crabs and shrimp have some chitin in their protective armors. Chitin in Arthropods and Crustaceans. Alone, chitin is translucent and not extremely hard, but in the exoskeletons of arthropods, it's intermixed with protein and pigments to form different degrees of hardness and a lot of different colors.
