Amylose and amylopectin are the two components of starch. Which of the following statement is true?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Amylose is water soluble and amylopectin is water insoluble
Starch is a polymer of α-glucose with two components:
Amylose — the water-soluble component (15–20% of starch), a long unbranched chain of α-D-glucose units joined by C1–C4 glycosidic links.
Amylopectin — insoluble in water (80–85% of starch), a branched polymer with C1–C4 links in the chain and C1–C6 links at the branches.
Option (2) Both components are water insoluble — Incorrect. Amylose is the water-soluble part of starch.
Option (3) Both components are water soluble — Incorrect. Amylopectin, the major part, is insoluble in water.
Option (4) Amylopectin is water soluble and amylose is water insoluble. — Incorrect. It reverses the two components.
