Question

What is the disaccharide of melibiose and what is the type of glycosidic linkage present?

1) Sucrose, α-1,4-glycosidic linkage
2) Lactose, β-1,4-glycosidic linkage
3) Maltose, α-1,4-glycosidic linkage
4) Cellobiose, β-1,4-glycosidic linkage

Answer 1

The disaccharide of melibiose is cellobiose, and it is connected by a β-1,4-glycosidic linkage.

Step-by-step explanation:

The disaccharide of melibiose is cellobiose, which is formed by two D-glucose units connected by a β-1,4-glycosidic linkage. Melibiose is a disaccharide composed of D-galactose and D-glucose.
