Advantages/Disadvantages of Immobilising Enzymes

Witryna8 wrz 2014 · Sodium alginate will turn from liquid to solid when immersed in calcium chloride. This produces small beads with the enzyme inside. 2 Na (Alginate) + Ca++ -------> Ca (Alginate)2 + 2 Na+. • The substrate that the enzyme acts upon is able to diffuse through the gel, although this may be quite slow. • Immobilised enzymes are widely … WitrynaImmobilised enzymes are more stable because immobilising matrix protects enzyme molecules. Disadvantages. Immobilistaion requires additional time, equipment and materials so is more expensive to set up. Immobilised enzymes may be less active as they can not mix freely with the substrate. can laxatives help me lose weight
