Sugars have a(n) group that interacts with a group that forms ring structures when the dry molecule is placed in water.

carbonyl (-C=O)

hydroxyl (-OH)

Explanation:

Sugars have a carbonyl group that interacts with an hydroxyl group that forms a ring structure when the dry molecule is placed in water. Let take a look at sucrose for example.

Sucrose have the molecular formula of C₁₂H₁₂O₁₁. Its preparation is gotten from a juice of sugar cane. In the process of extracting the juice from sugar cane, the extraction process is done with water usually 80°C. The solution is then treated (purification) afterwards with slaked lime and carbon(iv)oxide. During this stage, the (-C=O) group interfere with the OH group in order to form a ring structure.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
