Identifying Monosaccharides

1. Definition of Monosaccharides:
   Monosaccharides are the simplest form of carbohydrates and cannot be hydrolyzed into simpler sugars. They typically consist of a single sugar unit.

2. List of Given Molecules:

   • Sucrose
   • Galactose
   • Lactose
   • Fructose
   • Glucose

3. Analysis of Each Option:

   • Sucrose: This is a disaccharide composed of glucose and fructose.
   • Galactose: This is a monosaccharide, a single sugar unit.
   • Lactose: This is a disaccharide made up of glucose and galactose.
   • Fructose: This is a monosaccharide, another single sugar unit.
   • Glucose: This is also a monosaccharide, a fundamental sugar in biology.

Final Answer

The three molecules that are monosaccharides are galactose, fructose, and glucose.
