Question Explanation: Analysis of the chemical components and structure of starch.

Concept: Structural composition of Starch.

Solution:

Starch is a polymer of $α$ - D-glucose consisting of two components: Amylose (water-soluble, unbranched with $C_{1} - C_{4}$ linkages) and Amylopectin (water-insoluble, branched with $C_{1} - C_{4}$ and $C_{1} - C_{6}$ linkages).

Statement 1: Correct; it is a polymer of $α$ -D-glucose.

Statement 2: Correct; Amylose is water-soluble and unbranched.

Statement 3: Correct; Amylopectin is insoluble and branched at $C_{1} - C_{6}$ .

Statement 4: Correct; Glycogen is the storage form in animals and is called animal starch.

Final Answer: 1, 2, 3, 4 (All statements are correct)
