Assertion (A): Denatured protein have decreased solubility. Reason (R): The hydrophobic groups are generally located inside protein molecules, during denaturation, these molecules get exposed onto molecule surface, which decreases the solubility.
Assertion (A): Amylose is more susceptible to retrogradation. Reason (R): It is not due to its linear structure.
