Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
true or false? amylopectin is what makes up most of starch molecules.
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Amylopectin, the counterpart of amylose, is the major component of starch by weight and one of the largest molecules found in nature. It also is composed of linear chains of (1→4) linked -d-glucopyranosyl units but with a much greater extent of -(1→6) branching than amylose.

Detailed explanation-2: -Starch is a chain of glucose molecules which are bound together, to form a bigger molecule, which is called a polysaccharide. There are two types of polysaccharide in starch: Amylose – a linear chain of glucose. Amylopectin – a highly branched chain of glucose.

Detailed explanation-3: -Starch contains two glucose polymer components – amylopectin and amylose. Both polymers have -1, 4-linked linear chains and -1, 6-linked branch points. Amylose is primarily linear and has very few branches.

Detailed explanation-4: -It has C 1-C 6 branching between glucose units of different strands.

Detailed explanation-5: -Glucose is the monosaccharide that makes up the starch.
