Studies on Chitin VI. The Nature of ?- and ?-Chitins [PDF]

Australian Journal of Biological Sciences, 1965
Enzymic digestion, acidic hydrolysis, deuterium exchange, infrared absorption spectra, and differential thermal analysis of chitins show that not only do the structures ...

Chitin nanofiber elucidates the elicitor activity of polymeric chitin in plants

Frontiers in Plant Science, 2015
Chitin, an N-acetyl-D-glucosamine polymer, is a component of fungal cell walls and a microbe/pathogen-associated molecular pattern that elicits plant defense responses.

Chitin Research Revisited

Marine Drugs, 2010
Two centuries after the discovery of chitin, it is widely accepted that this biopolymer is an important biomaterial in many aspects. Numerous studies on chitin have focused on its biomedical applications.

Suppression of Chitin-Triggered Immunity by a New Fungal Chitin-Binding Effector Resulting from Alternative Splicing of a Chitin Deacetylase Gene

Journal of Fungi, 2022
Phytopathogenic fungi have evolved mechanisms to manipulate plant defences, such as chitin-triggered immunity, a plant defensive response based on the recognition of chitin oligomers by plant-specific receptors.

Synthesis and Physicochemical Characterization of Chitin Derivatives

Journal of Chemistry, 2013
Firstly, chitin derivatives were synthesized. For this purpose, chitin was modified via ring-opening reaction with cyclic anhydrides in lithium chloride/N,N-dimethylacetamide.

Growth on Chitin Impacts the Transcriptome and Metabolite Profiles of Antibiotic-Producing Vibrio coralliilyticus S2052 and Photobacterium galatheae S2753

mSystems, 2017
Members of the Vibrionaceae family are often associated with chitin-containing organisms, and they are thought to play a major role in chitin degradation.

The presence of α-chitin in Tardigrada with comments on chitin in the Ecdysozoa

Zoologischer Anzeiger - A Journal of Comparative Zoology, 2016
Abstract We used Fourier Transform Infrared Spectroscopy (FT-IR) to characterize for the first time chitin in the cuticle of a eutardigrade ( Macrobiotus cf. hufelandi ). Analysis of the isolated cuticles of single individuals and comparison with commercial α-chitin isolated from shrimp shell and β-chitin from squid pen revealed that the amide I ...

Chitin induces steroid-resistant airway inflammation and airway hyperresponsiveness in mice

Allergology International, 2021
Background: Previous reports have shown that pathogen-associated patterns (PAMPs) induce the production of interleukin (IL)-1β in macrophages. Moreover, studies using mouse models also suggest that chitin, which acts as a PAMP, induces adjuvant effects ...

Chitin Nanowhisker Aerogels [PDF]

ChemSusChem, 2013
AbstractChitin nanowhiskers are structured into mesoporous aerogels by using the same benign process used previously in our group to make cellulose nanowhisker aerogels. The nanowhiskers are sonicated in water to form a hydrogel before solvent‐exchange with ethanol and drying under supercritical CO2 (scCO2). Aerogels are prepared with various densities

Influence of synthesis approach and formulation on the physicochemical properties of chitin and chitosan from Black Soldier Fly

Results in Engineering
In recent years, numerous studies have emerged on the application of biosorbents for dyes removal from wastewater. Chitosan, a derivative of chitin, is particularly effective as a flocculant for this purpose.
