Which monosaccharide is formed by the hydrolysis of starch?

The hydrolysis of starch predominantly results in the formation of glucose. Starch is a polysaccharide made up of long chains of glucose units linked by glycosidic bonds. During the hydrolysis process, which can be facilitated by enzymes such as amylase, these bonds are broken, releasing individual glucose molecules.

While maltose, a disaccharide composed of two glucose units, may also be produced as an intermediate during the breakdown of starch, the end product of complete hydrolysis is glucose. Thus, glucose is the primary monosaccharide derived from starch hydrolysis.

Other monosaccharides like sucrose and fructose are not directly formed from starch; sucrose is a disaccharide consisting of glucose and fructose, while fructose is a simple sugar found in fruits and honey, not linked to starch digestion. Therefore, glucose is the correct answer in this context.
