Evaluating Assertion and Reason:

Assertion A: Amylose is insoluble in water — FALSE ✗

Amylose is actually soluble in water (it forms a colloidal solution). It is the amylopectin component that is less soluble. Amylose dissolves in hot water to form a blue-black complex with iodine.

Reason R: Amylose is a long linear molecule with more than 200 glucose units — TRUE ✓

Amylose is indeed a linear (unbranched) polymer of -D-glucose with -1,4 glycosidic linkages, typically containing 200–1000 gluc
