Temperature and time-dependent self-assembly and gelation behavior of chitin in aqueous KOH/urea solution

Giant, 2020
Chitin is the most abundant natural glycosaminoglycan that is derived from marine crustaceans and has enormous potential in biomedical applications because of its high similarity in chemical structure to the component of extracellular matrix.

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.

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 ...

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.

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.

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.

Large scale preparation of single chitin oligomers by the combination of homogeneous acid hydrolysis and reversed phase preparative chromatography

Carbohydrate Polymer Technologies and Applications, 2020
Chitin oligomers received increased research and commercial attention recently because of their many excellent biological activities. However, most of these studies were based on heterogeneous oligomer mixtures.

Extraction, Quantification, and Characterization of Chitin from Marine Biofouling Organisms Amphipods (Jassa sp.) and Hydroids (Coryne sp.)

Polysaccharides
As the demand for chitin grows, new chitin sources with unique physicochemical properties are required. Abundant biofouling species, such as amphipods and hydroids, have chitinous skeletal systems that can be utilized for chitin production.

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 ...
