Phosphate groups are naturally present in starch at C3- or C6-position of the glucose residues and impact the structure of starch granules. Their precise quantification is necessary for understanding starch physicochemical properties and metabolism. Nevertheless, reliable quantification of Glc-3-P remains laborious and time consuming. Here we descr...

The impact of various degrees of acetylation on improving the thermal stability of xylan isolated from different botanical source has been studied; methylglucuronoxylan from birch and eucalyptus, arabinoglucuronoxylan from spruce and glucuronoarabinoxylan from sugarcane bagasse and straw. The lower molecular weight of non- acetylated methylglucuron...

This study reports the grafting of poly(ε-caprolactone) (PCL) on guar gum (GG) by in-situ ring-opening polymerization using tetra(phenylethynyl)tin (Sn(C≡CPh)4) as catalyst. The hydroxyl groups of guar gum act as initiators for ε-caprolactone ring-opening polymerization and the resulting poly(ε-caprolactone) binds covalently to the polysaccharide. ...

Magnetic hydrogel derived from wheat straw cellulose (WSC) and feather protein (FP) was successfully derived from [Bmim]Cl ionic liquids for copper nanoparticles carrier to prepare magnetic hydrogel-Cu (m-WSC/FP-Cu). Morphology, structure and component of m-WSC/FP-Cu were characterized by different techniques (SEM, TEM, XRD, FTIR, VSM, etc.). The a...

An amphiphilic polymer, carboxymethyl cellulose-laurate (CMC-C12), was synthesized by esterification of water-soluble carboxymethyl cellulose (CMC) and hydrophobic lauroyl chloride. Folate, a cancer-cell-specific ligand, was conjugated to CMC-C12 to obtain folate-CMC-C12 (FA-CMC-C12) which could be targeted to folate-receptor-overexpressing cancer ...

Waxy, normal, and high-amylose maize starches were acetylated to various degrees of substitution (DS) in aqueous medium. A stepwise addition of acetic anhydride enhanced reaction efficiency and DS was in the order of high-amylose maize starch (DS 1.72) > waxy maize starch (DS 1.60) > normal maize starch (DS 1.03) when 240% (w/w) acetic anhydride wa...

An efficient and one step production of acetylated and esterified chitin nanocrystals (CNCs) was successfully achieved using choline chloride-zinc chloride deep-eutectic solvent (ChCl-ZnCl2 DES). In this method, ChCl-ZnCl2 DES with a mole ratio of 1:2, was used for the esterification and O-acetylation of chitin at 90 °C for 3 h and 6 h. This strate...

DEAE-dextran hydrochloride is a positively charged biocompatible polyelectrolyte. Its behaviour in aqueous solutions - the changes in its colloidal characteristics and resulting conformation changes - were investigated using a combination of light scattering, densitometry and ultrasound spectrometry. The results indicated the formation of a volumin...

The objective of the study was to explore the utilization of residual Rose stems as a source of cellulose nanofibers (CNFs). The CNFs were obtained by a so-called conventional method and another one proposed in this study. They were characterized by Fourier-Transform Infrared spectroscopy (FTIR), X-ray diffraction, scanning, and transmission electr...

Neutron scattering measurements on the structure and dynamics of ternary solutions of microcrystalline cellulose (MC) in mixtures of an ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate and a polar organic solvent dimethylformamide (DMF) have shown that MC can be fully dissolved in solvent mixtures. Data also show the molecular partitioning of ...
