Condensation Reaction
Condensation Reaction — A chemical reaction in which two molecules combine with the loss of a small molecule (usually water), the fundamental reaction in peptide bond formation.
What Is a Condensation Reaction?
A condensation reaction joins two molecules with the loss of a small molecule, usually water. Peptide bond formation is a condensation reaction: the amino group of one amino acid reacts with the carboxyl group of another, releasing H2O. In SPPS, coupling reagents activate the carboxyl to make this energetically unfavorable reaction proceed efficiently.
Context
- Thermodynamics: Peptide bond formation is endergonic (+10 kJ/mol). Requires activation
- Activation: Coupling reagents (HATU, HBTU, DIC) convert -COOH to reactive ester
- Fragment condensation: Joining protected peptide segments in solution phase
