Introduction
Dehydration synthesis and hydrolysis reactions are fundamental chemical processes that play crucial roles in biological systems. Dehydration synthesis involves the removal of a water molecule to form a covalent bond between two molecules, while hydrolysis involves the addition of a water molecule to break a covalent bond.
Examples of dehydration synthesis include the formation of peptides from amino acids and the synthesis of polysaccharides from monosaccharides. Hydrolysis reactions, on the other hand, are involved in the breakdown of proteins, carbohydrates, and lipids during digestion.
Mechanisms of Dehydration Synthesis and Hydrolysis

Dehydration synthesis reactions typically involve three steps:
- Protonation of the nucleophile
- Nucleophilic attack on the electrophile
- Elimination of a water molecule
Hydrolysis
Hydrolysis reactions, on the other hand, involve the reverse process:
- Protonation of the electrophile
- Nucleophilic attack by water
- Elimination of a leaving group
