Question

Which is a disaccharide ?

Answer 1

Answer:

The common disaccharides are sucrose, lactose, and maltose.

Explanation:

Disaccharide is one type of carbohydrate. It is a simple sugar like glucose. The two monosaccharides link together to form a disaccharide. The monosaccharides combine with a glycosidic bond. These are soluble in water and sweet in taste. The most common disaccharide are sucrose, lactose, and maltose. The sucrose is the common table sugar and form by mixing glucose and fructose. Lactose is present in the milk. It is formed by combining glucose and glucose. Maltose is formed by glucose and glucose.

Answer 2

Answer:

A glycosidic bond between glucose and galactose will produce the disaccharide lactose, which is thus the correct answer.

Explanation:Sucrose is a disaccharide composed of glucose and fructose. Maltose is also a disaccharide composed of two glucose molecules. Moreover, fructose and xylose are monosaccharides.
