Statement-I:
Cane sugar is a disaccharide of α-D-glucose and β-D-fructose.
Cane sugar is sucrose.
The structure of sucrose consists of α-D-glucose and β-D-fructose units joined by an α,β-1 → 2 glycosidic linkage.
Statement-I is correct.
Statement-II:
Milk sugar is a disaccharide of α-D-glucose and β-D-galactose.
Milk sugar is lactose.
Lactose is composed of β-D-galactose and β-D-glucose, linked by a β - 1⟶4 glycosidic bond.
The glucose part in lactose is β-D-glucose, not α-D-glucose.
Statement-II is not correct.
