By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Enzymes and Coenzymes are discussed in a new report. According to news reporting originating in Konya, Turkey, by NewsRx journalists, research stated, "The article describes preparation of new calixarene biopolymers consisting of the immobilization of convenience calixarene derivative onto cellulose and chitosan biopolymers, and the encapsulation of these calixarene biopolymers with Candida rugosa lipase within a chemical inert sol-gel supported by polycondensation with tetraethoxysilane and octyltriethoxysilane."
The news reporters obtained a quote from the research from Selcuk University, "The catalytic properties of immobilized lipase were evaluated into model reactions employing the hydrolysis of p-nitrophenylpalmitate and the enantioselective hydrolysis of naproxen methyl esters from racemic prodrugs in aqueous buffer solution/isooctane reaction system. The resolution studies using sol-gel support have observed more improvement in the enantioselectivity of naproxen E = 300 with Cel-Calix-E than with encapsulated lipase without calixarene-based materials."
According to the news reporters, the research concluded: "Furthermore, the encapsulated lipase (Cel-Calix-E) was still retained about 39 % of their conversion ratios after the fifth reuse in the enantioselective reaction."
