Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True/False:Amylopectin is more soluble than Amylose in water.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Amylose is water soluble and amylopectin is water insoluble.

Detailed explanation-2: -Amylopectin exhibits better solubility than amylose due to the highly branched structure, although the latter has relative low molecular weight (amylose, 105; amylopectin, 107–109).

Detailed explanation-3: -Amylopectin is even less soluble due to the additional 1-6 glycosidic bonds on the branch chains, further reducing its H bonding potential and therefore reducing solubility in water.

Detailed explanation-4: -Both amylose and amylopectins are insoluble in water, but in hot water amylose dissolves to form a nonviscous solution, while amylopectin is insoluble but swells to form a viscous gel.
