Structural basis for directional chitin biosynthesis
Nature, 2022 Chitin, the most abundant aminopolysaccharide in nature, is an extracellular polymer consisting of N -acetylglucosamine (GlcNAc) units 1 . The key reactions of chitin biosynthesis are catalysed by chitin synthase 2 – 4 , a membrane-integrated ...

Chitin, Chitosan, and Nanochitin: Extraction, Synthesis, and Applications
Polymers, 2022 Crustacean shells are a sustainable source of chitin. Extracting chitin from crustacean shells is ongoing research, much of which is devoted to devising a sustainable process that yields high-quality chitin with minimal waste.

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

Chitin perception in plasmodesmata characterizes submembrane immune-signaling specificity in plants [PDF]
, 2020 The plasma membrane (PM) is composed of heterogeneous subdomains, characterized by differences in protein and lipid composition. PM receptors can be dynamically sorted into membrane domains to underpin signaling in response to extracellular stimuli.

Effects of Ball Milling, Ultrosonic or Hydrochloric Acid Treatment on the Microstructure and Enzymatic Deacetylation Efficiency of Chitin [PDF]
Shipin Kexue, 2023 Chitin is the second most abundant natural polysaccharide on Earth, which can be deacetylated to produce chitosan. However, due to the high crystallinity and poor solubility of chitin, its efficiency of enzymatic deacetylation is very low. To investigate

3D tomographic analysis of the order-disorder interplay in the Pachyrhynchus congestus mirabilis weevil [PDF]
Adv. Sci. 2022, 9, 2202145, 2022 The bright colors of Pachyrhynchus weevils originate from complex dielectric nanostructures within their elytral scales. In contrast to previous work exhibiting highly ordered single-network diamond-type photonic crystals, we here show by combining optical microscopy and spectroscopy measurements with 3D FIB tomography that the blue scales of P ...

Chitin-Induced Airway Epithelial Cell Innate Immune Responses Are Inhibited by Carvacrol/Thymol. [PDF]
, 2016 Chitin is produced in large amounts by fungi, insects, and other organisms and has been implicated in the pathogenesis of asthma. Airway epithelial cells are in direct contact with environmental particles and serve as the first line of defense against ...
