Detailed explanation-1: -Starch is comprised of two -glucan components namely amylose and amylopectin . Amylose is a linear polymer of glucose molecules linked by -1, 4-glycosidic linkages .
Detailed explanation-2: -Starch molecules exist in two forms – a simple linear polymer called amylose and a more complex branched form called amylopectin.
Detailed explanation-3: -Amylose consists of linear chains of (1 → 4)-linked d-glucose residues and is mainly in an amorphous state. Amylopectin with linear chains of (1 → 4)-linked d-glucose residues interconnected through (1 → 6)-glycosidic linkages, mainly presents a crystalline structure.
Detailed explanation-4: -Amylose is a polysaccharide made of -D-glucose units, bonded to each other through (1→4) glycosidic bonds. It is one of the two components of starch, making up approximately 20–30%.
