Synthesis of Urushiol-Tyrosine Resin and Immobilization of Polyphenol Oxidases
Abstract:
The urushiol-tyrosine resin(UTR) was synthesized from tyrosine and gasoline solution of urushiol by using anhydrous AlCl3 as catalyst. Its structure has been studied by IR, UV and DTA. The UTR-Cu was obtained by impregnation of UTR in Cu2+ solution. The polyphenol oxidase obtained from banana was immobilized on UTR-Cu complexes. The immobilized oxidase(UTR-Cu-En) had an activity of 1.1 A/(min·g), that is, 6.5 times greater than that of oxidase immobilized on active carbon. A possible structure of the UTR Cu immobilized enzyme is suggested.
