Question
Amylopectin is:
- Water soluble
- Water insoluble
- Forms colloidal solution with water
- Both (2) and (3)
Solution
Amylopectin is a type of polysaccharide and one of the two components of starch (the other being amylose). To answer your question, here are some details regarding its properties:
-
Water Solubility: Amylopectin is largely water-insoluble; however, it can dissolve partially in hot water, forming a viscous solution.
-
Colloidal Solution: When amylopectin is mixed with water, especially when heated, it can form a colloidal solution. This is due to its branched structure, which allows it to interact with water molecules.
-
Conclusion: Given these properties, the correct answer is "Both (2) and (3)", meaning that amylopectin is water-insoluble and can form a colloidal solution with water.
In summary, amylopectin exhibits characteristics of being largely water-insoluble while still being able to create a colloidal solution under certain conditions.
