Detailed explanation-1: -Starch is made of glucose monomers and occurs in both straight-chain and branched forms. Amylose is the straight-chain form, and consists of hundreds of linked glucose molecules. The branched form of starch is called amylopectin. In the small intestine, starch is hydrolyzed to form glucose.
Detailed explanation-2: -Starch is long chains of sugar molecules linked together like a chain. A single sugar molecule is a monosaccharide. Many sugar molecules linked together is a polysaccharide. Starch, therefore, is a polysaccharide.
Detailed explanation-3: -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-4: -Starches and sugars are examples of carbohydrates. Living things use them as their main source of energy. The monomers in sugar polymers are starch molecules. Plants and some animals use them for strength and rigidity.
