What is formed by the dehydration synthesis of sucrose?

In the process of dehydration synthesis, two monosaccharides combine to form a disaccharide while releasing a molecule of water. When sucrose is formed, it specifically results from the combination of one glucose molecule and one fructose molecule. During this reaction, a hydroxyl group from one sugar and a hydrogen atom from the other are removed, leading to the formation of water as a byproduct.

Given this understanding, the correct answer relates to the formation of water, which is a fundamental aspect of the dehydration synthesis reaction. This reaction is vital for the formation of various carbohydrates, including sucrose, and illustrates the principles of how simple sugars can polymerize into more complex forms, while simultaneously producing water as a result of bond formation.
