Verified step by step guidance

Understand the definition of a monosaccharide: Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar unit. They cannot be hydrolyzed into smaller carbohydrate units. Examples include glucose, fructose, and galactose.

Analyze the options provided: Sucrose, starch, glucose, and lactose. Determine which of these fits the definition of a monosaccharide.

Recall that sucrose is a disaccharide, composed of glucose and fructose linked by a glycosidic bond. It does not qualify as a monosaccharide.

Recognize that starch is a polysaccharide, made up of multiple glucose units linked together. It is not a monosaccharide.

Identify glucose as a monosaccharide because it is a single sugar unit and fits the definition of a simple sugar. Lactose, on the other hand, is a disaccharide composed of glucose and galactose.
