Question

Glucose molecules bond together in a process known as dehydration synthesis. What happens in this process?

Answer 1

Dehydration synthesis is a chemical reaction in which one or more molecules of water are removed from the reactants to form a new product. These reactions can occur when one of the reactants has a hydroxyl group (OH) that can be cleaved, thus forming the negatively charged hydroxide ion (OH -). The other reactant must have a hydrogen atom which can be cleaved to yield a hydrogen, or hydronium, ion (H+). In solution, these ions are free to combine and form a water molecule. The respective reactants are then able to form a chemical bond that creates a new compound.

Answer 2

Water is used as a reactant in order to build the polysaccharide molecule.

A water molecule is formed from the hydrogen and oxygen atoms removed.

The reaction uses water molecules to break the bonds in each glucose.

Water molecules are removed from each glucose molecule by the addition of heat.
