Question

What 2 monosaccharides are combined to make each a disaccharide?

1) Sucrose
2) Lactose
3) Maltose

Answer 1

Sucrose is formed from glucose and fructose, lactose from glucose and galactose, and maltose from two molecules of glucose.

Step-by-step explanation:

Glucose and fructose combine to form sucrose. Glucose and galactose combine to form lactose. Two glucose monomers combine to form maltose.

The combination of 2 monosaccharides through a dehydration reaction forms a disaccharide. Specifically:

Glucose and fructose combine to form sucrose

Glucose and galactose combine to form lactose

Two glucose molecules combine to form maltose.

These disaccharides are essential in our diet, providing energy and functioning as building blocks for more complex carbohydrates.
