MCQ
A sugar, that is not a disaccharide, among the following is
- ALactose
- ✓Galactose
- CSucrose
- DMaltose
✓
Answer
Correct option: B.
Galactose
b
disaccharide is the sugar formed when two monosaccharides are joined by glycosidic linkage. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose, and maltose. Galactose is a monosaccharide. When combined with glucose (monosaccharide), through a condensation reaction, the result is the disaccharide lactose. The hydrolysis of lactose to glucose and galactose is catalyzed by the enzymes lactase and $\beta$-galactosidase.
