Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Starch is an example of a polysaccharide found in plants. What is the monomer of starch (Hint:it is an example of a monosaccharide)?

A	sucrose
B	glucose
C	glycogen
D	lactose

Explanation:

Detailed explanation-1: -The storage polysaccharide that is found in plants is starch. It is made up of two parts: amylose and amylopectin. They are made up of glucose monomers.

Detailed explanation-2: -The basic chemical formula of the starch molecule is (C6H10O5)n. Starch is a polysaccharide comprising glucose monomers joined in 1, 4 linkages. The simplest form of starch is the linear polymer amylose; amylopectin is the branched form.

Detailed explanation-3: -Starch, glycogen, and cellulose are the polysaccharides made up of glucose monomers.

Detailed explanation-4: -Starch is a polymer that is formed by the repeated unit of glucose. Therefore, glucose is the basic unit of the polymer starch. Hence, glucose is considered as the monomer of starch.

Detailed explanation-5: -Starch: Amylose and Amylopectin Amylose consists of a linear, helical chains of roughly 500 to 20, 000 alpha-D-glucose monomers linked together through alpha (1-4) glycosidic bonds. Amylopectin molecules are huge, branched polymers of glucose, each containing between one and two million residues.
