A polysaccharide called starch consists entirely of glucose molecules. during early stages of starch digestion, starch would be broken down into Maltose

Explanation:

The start of the digestion happens in the mouth which is the first organ of the digestive system; the mouth contains salivary amylase that is present in the saliva.

The complete hydrolysis of starch yields, in successive stages, glucose:

starch → dextrins → maltose → glucose

This amylase breaks down starch into several units of Maltose and sends it to the next organ. This partially digested starch is completely digested into several glucose molecules in the intestine by various enzymes.

Maltose or malt sugar, is a disaccharide comprised of two glucose molecules. The most well-known disaccharide is sucrose, which is made of glucose and fructose.
