Why is the dehydration synthesis also called a condensation reaction?

Click For Summary

Discussion Overview

The discussion revolves around the terminology of dehydration synthesis and its alternative name, condensation reaction. Participants explore the implications of the term "condensation" in the context of biochemical reactions, particularly focusing on the formation of peptide bonds and phosphodiester bonds.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions whether the term "condensation" is appropriate, noting that it typically implies a phase change from gas to liquid and asking if nucleotides or amino acids were gases during bond formation.
  • Another participant suggests that "condensation" is simply a term used for different processes, referencing its Latin origin meaning "to thicken," which they argue fits both contexts.
  • A third participant explains that the formation of a peptide bond is classified as a condensation reaction because it results in the production of water (H2O) when two amino acids bond, detailing the specific contributions of the amine and acid groups.

Areas of Agreement / Disagreement

Participants express differing views on the appropriateness of the term "condensation" in this context, indicating that multiple competing interpretations remain without a clear consensus.

Contextual Notes

Some assumptions about the definitions of "condensation" and the specific biochemical processes involved may not be fully articulated, leading to potential ambiguity in the discussion.

Doesn't condensation imply a change from a gas to a liquid?

Were the nucleotides gases when the phosphodiester bond formed?
Were the amino acids gases when the peptide bond formed?

It is just the same name used for two different processes. In latin condensatio means to thicken, it happens that it fits both cases.

Thanks.
 
The formation of the peptide bond is called a condensation reaction since one H2O is produced when two amino acids bond.
The NH3 amine group donates one H and the COOH acid group donates an
OH . The peptide bond then is between N-C
