kitiinikuori
Kitiinikuori is the external covering of many arthropods, as well as some other organisms, consisting primarily of the polysaccharide chitin bound with proteins. In Finnish biology, the term literally means a chitinous shell or cuticle. The kitiinikuori provides both shape and protection, supports muscle attachment, and forms a barrier against dehydration and pathogens.
Chitin, a long polymer of N-acetylglucosamine, forms multiple layers in the cuticle. The outer epicuticle minimizes
Growth occurs through molting (ecdysis), when the old kitiinikuori is shed and a new one secreted by
Beyond its biological role, the kitiinikuori has inspired biomaterials research because it combines lightness with toughness
