What is the difference between dehydration synthesis and hydrolysis?


Quick Answer

The difference between dehydration synthesis and hydrolysis is that in one, bonds are being formed, while in the other bonds are being destroyed. Dehydration synthesis bonds molecules together by removing water. In hydrolysis, water is added to the molecules in order to dissolve those bonds.

Full Answer

Dehydration synthesis and hydrolysis perform two different jobs when it comes to macromolecules or polymers. Polymers are molecules linked together covalently. According to the website About, when water is subtracted from the chemical equation, small molecules, or monomers, bond together to form polymers. In order to break down these compounds, water must be added to the equation. For instance, carbohydrates are an example of a polymer. Carbohydrates are made up of sugar monomers bonded together when water is leached from them. In order for people to digest carbohydrates, they must be broken down, which occurs the second water is introduced back to the sugar monomers.

According to the Peace Org, hydrolysis is merely the inverse operation of dehydration synthesis.The more water that is leached out of these sugar molecules, the longer the carbohydrate chain becomes, forming polysaccharides. This same process is necessary to forming and breaking down proteins and nucleic acids. The only organic macromolecules it does not work on are lipids.
