Verified step by step guidance

Understand the definition of monosaccharides: Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar unit. Examples include glucose, fructose, and galactose.

Review the given options: Sucrose, maltose, and lactose are disaccharides, meaning they are composed of two monosaccharide units linked together by a glycosidic bond.

Identify the correct answer: Glucose is a monosaccharide because it is a single sugar unit and does not require hydrolysis to break down into simpler sugars.

Explain why the other options are not monosaccharides: Sucrose is composed of glucose and fructose, maltose is composed of two glucose units, and lactose is composed of glucose and galactose. These are all disaccharides.

Conclude the reasoning: Based on the definitions and compositions, glucose is the correct answer as it fits the criteria of being a monosaccharide.
