2. The disaccharide present in milk is lactose.
3. Starch is a polymer of glucose.
Which of the statement given above is/are correct?

• A. Only 1
• B. Only 2
• C. 1 and 2
• D. 1, 2 and 3

Answer 1

The correct option is D 1, 2 and 3

Fructose is the sweetest of all sugars. It is 1.7 times sweeter than sucrose.

The disaccharide present in milk is lactose. Lactose is the major carbohydrate in the milk of most species. Lactose is a disaccharide composed of the monosaccharides D-glucose and D-galactose, joined in a $\beta$-1,4-glycosidic linkage.

Starch is a glucose polymer in which glucopyranose units are bonded by alpha-linkages. It is made up of a mixture of amylose (15–20%) and amylopectin (80–85%).

All the statements are correct.
