Once starch in a person's diet has been broken down into _____, those subunits are absorbed in the small intestines.
Murrr4er [49]

Once starch in a person's diet has been broken down into monosaccharides those subunits are absorbed in the small intestines

Carbohydrates, also referred to as sugars, are a type of polymer. They are polymers whose subunits are linked together by glycosidic linkages that, when water is released, form a bond between two monomeric units. The amount of monomers that must come together to make a carbohydrate allows for the division of the carbohydrates into various groups. The monosaccharide, commonly known as simple sugars, is the most basic type of carbohydrate chain.

Since they exist as a single unit and are not connected to any other monosaccharides, these molecules are frequently referred to as the monomers of a carbohydrate chain.

To learn more about monosaccharides refer the link:
