Distinct cellular and molecular mechanisms contribute to the specificity of the two Drosophila melanogaster chitin synthases in chitin deposition. [PDF]

open access: yesPLoS Genetics
Chitin is a major component of arthropod extracellular matrices, including the exoskeleton and the midgut peritrophic matrix. It plays a key role in the development, growth and viability of insects.

Crustacean shell waste derived chitin and chitin nanomaterials for application in agriculture, food, and health – A review

open access: yesCarbohydrate Polymer Technologies and Applications, 2023
Chitin, a widely available natural polymer, is the fundamental structural component of crustacean shells. The crustacean processing industry produces a lot of shell waste each year (in millions), most of which is discarded and poses serious environmental

Extraction and characterization of chitin from granary weevil, Sitophilus granaries L. (Coleoptera: Curculionidae) [PDF]

open access: yesArthropods, 2022
Insect chitin has been extracted from granary weevil - Sitophilus granarius L, commonly called wheat weevil in laboratory by treating it with 1 M HCl and 1 M NaOH. This was followed by decolorization. The yield of chitin from this species is 20.2%.

A dynamic interplay between chitin synthase and the proteins Expansion/Rebuf reveals that chitin polymerisation and translocation are uncoupled in Drosophila.

open access: yesPLoS Biology, 2023
Chitin is a highly abundant polymer in nature and a principal component of apical extracellular matrices in insects. In addition, chitin has proved to be an excellent biomaterial with multiple applications.

A study on structural comparisons of α-chitin extracted from marine crustacean shell waste

open access: yesCarbohydrate Polymer Technologies and Applications, 2021
In the present study, chitin was extracted from marine crustacean shell waste (shrimp, crab, squilla and lobster) using traditional chemical methods (deproteinisation and demineralization) and its physicochemical and structural properties were ...
