Mass Transport Limitations and Kinetic Consequences of Corn Stover Deacetylation

open access: yesFrontiers in Energy Research, 2022
Alkaline pretreatment of herbaceous feedstocks such as corn stover prior to mechanical refining and enzymatic saccharification improves downstream sugar yields by removing acetyl moieties from hemicellulose.

Chitosan: Sources, Processing and Modification Techniques

open access: yesGels, 2022
Chitosan, a copolymer of glucosamine and N-acetyl glucosamine, is derived from chitin. Chitin is found in cell walls of crustaceans, fungi, insects and in some algae, microorganisms, and some invertebrate animals. Chitosan is emerging as a very important

Histone Deacetylation

open access: yesDrugs in R & D, 2008
Recent research has elucidated another mechanism for gene expression and signalling protein regulation in malignant cells. Histone deacetylases (HDACs) have been associated with silencing of tumour suppressor genes, and with other functions that promote malignant cell phenotype, such as the function of the chaperone protein heat shock protein (HSP)-90.

Acetate Revisited: A Key Biomolecule at the Nexus of Metabolism, Epigenetics and Oncogenesis—Part 1: Acetyl-CoA, Acetogenesis and Acyl-CoA Short-Chain Synthetases

open access: yesFrontiers in Physiology, 2020
Acetate is a major end product of bacterial fermentation of fiber in the gut. Acetate, whether derived from the diet or from fermentation in the colon, has been implicated in a range of health benefits.

JNK‐mediated Ser27 phosphorylation and stabilization of SIRT1 promote growth and progression of colon cancer through deacetylation‐dependent activation of Snail

open access: yesMolecular Oncology, 2022
Sirtuin 1 (SIRT1), an NAD+‐dependent histone/protein deacetylase, has multifaceted functions in various biological events such as inflammation, aging, and energy metabolism. The role of SIRT1 in carcinogenesis, however, is still under debate.

Piezoelectric Performance of Microbial Chitosan Thin Film Derived from Aspergillus oryzae

open access: yesInternational Journal of Renewable Energy Development, 2022
In this study, chitosan thin film derived from Aspergillus oryzae cell walls was fabricated and characterised. First, the chitosan from the fungal biomass was extracted (0.18 g/g) with 52.25% of degree of deacetylation obtained through Fourier transform ...

Green fabrication of chitosan from marine crustaceans and mushroom waste: Toward sustainable resource utilization

open access: yesGreen Processing and Synthesis, 2023
The exoskeletons of crabs, shrimp, and fish are major waste. These wastes contain chitin, an abundant natural polymer found next to cellulose. Thus, disposal of this waste becomes a huge problem for the environment; besides this, reutilization boosts the

Chitin and Chitosan Preparation from Marine Sources. Structure, Properties and Applications

open access: yesMarine Drugs, 2015
This review describes the most common methods for recovery of chitin from marine organisms. In depth, both enzymatic and chemical treatments for the step of deproteinization are compared, as well as different conditions for demineralization.

Recycling Cohesin Rings by Deacetylation [PDF]

open access: yesMolecular Cell, 2010
In this issue of Molecular Cell, Beckouët et al. (2010) and Borges et al. (2010) identify the enzyme responsible for cohesin deacetylation in anaphase and show that de novo acetylation is required for cohesion establishment in the next cell cycle.

CHITOSAN PREPARATION WITH MULTISTAGE DEACETYLATION OF CHITIN AND INVESTIGATION OF ITS PHYSICOCHEMICAL PROPERTIES

open access: yesIndonesian Journal of Chemistry, 2010
Study of chitosan prepared with chitin deacetylation by multistage alkali treatments has been done. Chitin was extracted from Lampung white shrimp's (Litophenaeus vannamei) shell. The FTIR spectroscopy was used to determine deacetylation degree of chitin/
