Immobilised lactase
This simple practical investigation introduces students to the principles of digestion and enzyme immobilisation. It can be used as the starting point for other, more advanced activities such as the regulation of lactase production in Escherichia coli (the lacoperon), the evolution and social significance of … Zobacz więcej Lactase (beta-galactosidase) catalyses the hydrolysis of lactose to glucose and galactose: Lactose -> D-glucose + beta-D-galactose Both of these sugars taste sweeter and are … Zobacz więcej This activity takes about 40 minutes. The sodium alginate takes some time to dissolve, so the solution is best prepared before the … Zobacz więcej The immobilised enzyme column may also be used to treat whey, producing a sweet whey syrup which is widely used in confectionery (it is usually described on labels as ‘hydrolysed whey syrup’ or just ‘whey syrup’). … Zobacz więcej WitrynaThere are many industrial and medical applications of immobilised enzymes, including production of the following:. Lactose-free dairy products such as milk. Enzyme: Lactase; Converts lactose to glucose and galactose; Semi-synthetic penicillin which overcomes issues of penicillin resistance.
