Carbohydrates consist of fundamental building blocks
(monomers) known as saccharides or sugars. In living organisms. the
sugars known as monosaccharides, disaccharides, and polysaccharides
are of most importance. One of the common monosaccharides which are
of great importance to living things is glucose. Use the molecular model
material to construct two molecules of glucose (Figure 4).

Construct two glucose molecules.
If two monosaccharide molecules are combined by dehydration synthesis,
the result is a disaccharide. If many are combined, a polysaccharide is
formed. For example, starch is a polysaccharide type of carbohydrate
composed of many glucose molecules combined together.

To construct a disaccharide molecule known as maltose,
join your two glucose molecules together by bringing the
hydroxyl group at the end of one molecule (reactive
group #1) next to the hydroxyl group at the opposite end of
the other glucose molecule (reactive group #2 of the other
molecule). (See Figure 5 for which hydroxyl groups to
use.) Remove a molecule of water and attach the two
glucose molecules together.

Expert Solution

Step 1(Introduction)

-When dehydration occurs the molecules of carbohydrates (monosaccharides) are joined together to form disaccharides or polysaccharides(starch).

-Disaccharides are formed when two monosaccharides are joined together by the process of dehydration, when more than two molecules of monosaccharides are combined together through dehydration reaction , it forms polysaccharides(starch).

Answer: Hence answer to question-5 is , when dehydration occurs the molecules of carbohydrates join together.
