Electrokinetic and adsorption properties of sepiolite modified by 3-aminopropyltriethoxysilane.
Surface modification of clay minerals has become increasingly important for improving the practical applications of clays such as fillers and adsorbents. An investigation was carried out on the surface modification of sepiolite with aminopropylsilyl groups in 3-aminopropyltriethoxysilane (3-APT). The zeta potential of the modified sepiolite suspensions was measured as a function of initial elec...
متن کاملImmobilization of invertase in conducting polymer matrices.
This paper reports a novel approach in the electrode immobilization of an enzyme, invertase, by electrochemical polymerization of pyrrole in the presence of enzyme. The polypyrrole/invertase and polyamide/polypyrrole/invertase electrodes were constructed by the entrapment of enzyme in conducting matrices during electrochemical polymerization of pyrrole. This study involves the preparation and c...
متن کاملMultipoint Immobilization of Invertase on Agarose: Stability and Kinetic Properties
Enzyme immobilization is a specific method for restricting the enzyme freedom of movement. There are strategies for the proteins multipoint immobilization by amine-terminal residues, lysine residues and carboxylic groups. In the present work, a commercial invertase of Saccharomyces cerevisiae underwent multipoint immobilization on glyoxyl-agarose, amineagarose and glutaraldehyde-agarose support...
متن کاملMechanism of coupling periodate-oxidized nucleosides to proteins.
This paper describes a mechanism of coupling periodate-oxidized nucleosides to proteins. Each of the dialdehyde groups of a periodate-oxidized nucleoside is shown to couple to lysine residues on different protein molecules through Schiff bases, thereby cross-linking different protein molecules, forming a polymer. This is in contrast to the previous model in which nucleosides were suggested to c...
متن کاملPeriodate Oxidation of Methylcellulose: Characterization and Properties of Oxidized Derivatives
In this paper, the behavior of oxidized methylcelluloses is compared with that of the initial methylcellulose, an amphiphilic cellulose derivative. Methylcelluloses are important for many applications in the cosmetic and food industries. The mechanism of thermo-gelation of methylcellulose is briefly explained as well as the method of oxidation of polysaccharides. Then, our experiments involve t...
