Question

Alginates are used for enzyme immobilisation because

• A. They are insulators
• B. They have good water holding capacity
• C. They are inert
• D. Both B and C

Answer 1

The correct option is D Both B and C

Alginate is a natural polymer that is derived from the cell wall of algae. The most commonly used supporters of enzyme immobilisation are calcium and magnesium alginate. The advantages of alginate are that they are inert in nature, so they do not interfere chemically with any analyte and also they have a very good water holding capacity. Therefore the correct answer is option D.
