Statement A is correct because glucose exists in two anomeric forms, α-D-glucose and β-D-glucose.
Statement B is correct because the two anomers differ only in the configuration of the hydroxyl group at C−1, which is the anomeric carbon in the cyclic hemiacetal structure.
Statement C is incorrect because the melting point of the α-anomer is 419 K, which is less than the melting point of the β-anomer (423 K).
Statement D is incorrect because the specific rotation of the α-anomer is +112∘ and that of the β-anomer is +19∘.
Statement E is correct because the α-form is obtained by crystallization from a concentrated solution of glucose at 303 K, while the β-form is obtained by crystallization from a hot and saturated aqueous solution at 371 K.
Thus, statements A, B, and E are correct.
