Subject : Chemistry

Question:

Summarizes the relationship between dehydration reactions and hydrolysis.

Expert Verified Solution:

Dehydration reactions and hydrolysis are opposite processes that play crucial roles in the formation and breakdown of organic molecules.

1. Dehydration Reactions: These reactions, also known as condensation reactions, involve the joining of two molecules with the removal of a water molecule. During dehydration synthesis, a covalent bond forms between two subunits, and water is released as a byproduct. This process is essential in the synthesis of complex molecules such as proteins, nucleic acids, and polysaccharides from simpler subunits.

2. Hydrolysis: Hydrolysis is the reverse process of dehydration synthesis. It involves the breaking down of complex molecules into simpler ones through the addition of water. In hydrolysis, a water molecule is used to cleave the bonds between subunits of a polymer, effectively reversing the dehydration reaction. This process is crucial in digestion and the breakdown of biological macromolecules.
