Immobilised enzymes practical
WitrynaLactase is an immobilised enzyme in porous beads and used to convert lactose into sweeter tasting sugars- glucose and galactose. These products are then used to replace condensed milk in the manufacture of soft toffee and caramel. _____ 2011 WHAT IS MEANT BY THE TERM METABOLISM.

An immobilized enzyme is an enzyme, with restricted mobility, attached to an inert, insoluble material—such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride). This can provide increased resistance to changes in conditions such as pH or temperature. It also lets enzymes be held in place throughout the reaction, foll… WitrynaWe can use free enzymes in solution in a number of cases; however, in many practical applications, it is advantageous to employ enzymes in an immobilized form. In general, ‘enzyme immobilization‘ is defined as restricting the enzyme molecules to a fixed space; it is achieved by fixing the enzyme to, or within, a macroscopic support matrix ...
