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 ...

Chitin-induced systemic disease resistance in rice requires both OsCERK1 and OsCEBiP and is mediated via perturbation of cell-wall biogenesis in leaves

open access: yesFrontiers in Plant Science, 2022
Chitin is a well-known elicitor of disease resistance and its recognition by plants is crucial to perceive fungal infections. Chitin can induce both a local immune response and a systemic disease resistance when provided as a supplement in soils.

Effects of Ball Milling, Ultrosonic or Hydrochloric Acid Treatment on the Microstructure and Enzymatic Deacetylation Efficiency of Chitin [PDF]

open access: yesShipin 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

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

open access: yesGiant, 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.

Imobilisasi Asam Humat Pada Kitin Dan Aplikasinya Sebagai Adsorben Cr(III)

open access: yesIndonesian Journal of Chemical Research, 2018
Immobilization of humic acid on chitin has been conducted and applied to the adsorption of Cr(III). The humic acid was isolated using NaOH 0.1 M, while chitin was isolated by deproteination of crab shells by using NaOH 3.5 % (w/v) and followed by ...

Chitin nanofiber elucidates the elicitor activity of polymeric chitin in plants

open access: yesFrontiers 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.

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

open access: yesJournal 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

open access: yesJournal 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.
