Question

What three disaccharides are formed from the monosaccharides glucose, fructose, and galactose?

A. Maltose, lactose, and sucrose.
B. Glucose, fructose, and sucrose.
C. Maltose, fructose, and lactose.
D. Glucose, galactose, and lactose.

Answer 1

Maltose, lactose, and sucrose are the three disaccharides formed from glucose, fructose, and galactose.

Step-by-step explanation:

The three disaccharides formed from the monosaccharides glucose, fructose, and galactose are:

1. Maltose: formed by the dehydration reaction between two glucose molecules.
2. Lactose: consisting of the monomers glucose and galactose, naturally found in milk.
3. Sucrose: composed of the monomers glucose and fructose, the most common disaccharide known as table sugar.
