Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Starch has two different types:
A
Maltose and Lactose
B
Maltose and Sucrose
C
Lactose and Sucrose
D
Amylose and Amylopectin
Explanation: 

Detailed explanation-1: -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-2: -Starch is composed of two types of polysaccharides: amylose, a linear (1–4) linked glucan, and the much larger amylopectin, an (1–4) linked glucan that contains around 5% (1–6) linkages resulting in a branched molecule [5].

Detailed explanation-3: -Starch consists of glucose molecules. It can occur in two forms: amylose and amylopectin. Amylose is a linear or straight-line polymer that scientists describe as amorphous or solid. Amylopectin forms a branched chain and is crystalline.

Detailed explanation-4: -Amylose is a linear polysaccharide in which glucose residues are linked solely by -1, 4 glycosidic bonds. In contrast, amylopectin is a branched molecule in which the branch points consist of -1, 6 glycosidic bonds while the linear portions of the branches are made up of -1, 4 bond as in amylose (Fig.
