Five water-soluble chitosan derivatives were carried out by quaternizing either iodomethane or N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride (Quat188) as a quaternizing agent under basic condition. The degree of quaternization (DQ) ranged between 28±2% and 90±2%. The antifungal activity was evaluated by using
The congenital disorders of glycosylation (CDG), a group of inherited diseases characterized by aberrant glycosylation, encompass a wide range of defects, including glycosyltransferases, glycosidases, nucleotide-sugar transporters as well as proteins involved in maintaining Golgi architecture, pH and vesicular trafficking. Mutations

The photodissociation of methyl iodide in the A band is studied by full-dimensional (9D) wave packet dynamics calculations using the multiconfigurational time-dependent Hartree approach. The potential energy surfaces employed are based on the diabatic potentials of Xie et al. [J.
Solvents have a profound influence on chemical reactions in solution and have long been used to control their outcome. Such effects are generally considered to be governed by thermodynamics; however, little is known about the steric effects of solvent molecules.

A combination of multistage mass spectrometry experiments and DFT calculations were used to examine the synthesis and reactivity of dimethylaurate. Collision induced dissociation (CID) of [(CH(3)CO(2))(4)Au](-) proceeded via reductive elimination of acetylperoxide to yield the diacetate [CH(3)CO(2)AuO(2)CCH(3)](-), which in turn
