Is glucose ionic or covalent? Sucrose has the chemical formula C12H22O11. While Myristic acid has a chemical formula C14H28O2. What functional groups are present in each molecule? How do you find the empirical formula from the molecular formula?
The CNT was functionalized with polymerized ionic liquid (PIL) through direct polymerization of the ionic liquid 1-vinyl-3-ethylimidazolium tetrafluoroborate on the carbon nanotubes, and then used as a support for the highly dispersed PtNPs. The electrochemical performance of the PtNPs/PIL-CNTs ...
The glucose isomerase GICA from Caldicoprobacter algeriensis was immobilized by ionic adsorption on polymethacrylate carriers (Sepabeads EC-EA and EC-HA) or covalent attachment to glyoxal agarose. The Sepabeads EC-HA yielded the highest recovery of activity (89%). The optimum temperature and pH ...
The swelling behavior of these materials may be dependent on pH, temperature, ionic strength, or even glucose concentration. In particular, there has been increased research interest in the development of glucose-sensitive polymeric systems that deliver appropriate amounts of insulin in response 23 ,...

Oxidoreductases, such as glucose oxidase, can be electrically "wired" to electrodes by electrostatic complexing or by covalent binding of redox polymers so that the electrons flow from the enzyme, through the polymer, to the electrode. We describe two materials for amperometric biosensors based on ...
direct ORR can be seen (voltammogram b). Appending polar functional groups such as carboxylic acid to the aromatic compounds enhance the possible interactions such as Van Der-Waals and hydrogen bond or even covalent bonding between a solid surface and enzymes, lead to suitable orientation of immobi...

However, native proteins are often susceptible to environmental stressors, including changes in pH, ionic strength, and exposure to digestive enzymes, and high temperatures, which may result in precipitation, aggregation, hydrolysis, and denaturation, leading to emulsion stratification or droplet ...
The immobilization of glucose oxidase can be effected by conventional means such as ionic bonding, covalent bonding or entrapping method. According to the ionic bonding method, an aqueous glucose oxidase solution to which a buffer solution (e.g., 0.1-1 M phosphate buffer) is added may be conta...
