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

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

PLoS 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.

The influence of chitin structure on its enzymatic deacetylation

Chemical and Process Engineering, 2016
The possibility of producing chitosan by enzymatic deacetylation of chitin has been the subject of numerous investigations over the last twenty years, but to date no satisfactory method has been developed.

Priming and elongation of chitin chains: Implications for chitin synthase mechanism

The Cell Surface, 2019
Most fungi have multiple chitin synthases (CSs) that may make chitin at different sites on the cell surface, at different times during growth, and in response to cell wall stress.

A secreted LysM effector protects fungal hyphae through chitin-dependent homodimer polymerization.

PLoS Pathogens, 2020
Plants trigger immune responses upon recognition of fungal cell wall chitin, followed by the release of various antimicrobials, including chitinase enzymes that hydrolyze chitin.

Characterization of Early, Chitin-Induced Gene Expression in Arabidopsis

Molecular Plant-Microbe Interactions, 2002
Three genes (i.e., a zinc finger protein, a lectin-like protein, and AtMPK3), previously shown to respond to chitin elicitation in microarray experiments, were used to examine the response of Arabidopsis spp. to chitin addition. Maximum induction for all

Production of 5-Hydroxymethylfurfural from Chitin Biomass: A Review

Molecules, 2020
Chitin biomass, a rich renewable resource, is the second most abundant natural polysaccharide after cellulose. Conversion of chitin biomass to high value-added chemicals can play a significant role in alleviating the global energy crisis and ...

Pretreatment of chitin depolymerization by expansin-like protein to improve hydrolysis efficiency

Heliyon
Chitin is a polysaccharide similar to cellulose that contains abundant hydrogen bonds. Expansin-like proteins disrupt hydrogen bond networks, causing cellulose to swell and accelerating its degradation.

Applications and interest of chitin, chitosan and their derivatives in enology

OENO One, 2005
This review treats of the possible use interest of chitin, chitosan and derivatives in enology. Chitosan and chitin are polysaccharide polymers containing more than 5 000 glucosamine and acetylglucosamine units, respectively, and their molecular weights ...
