Definition

Meaning and Definition

The chemical process of introducing a carboxyl group (-COOH) into a molecule.

A biochemical reaction, often enzyme-catalyzed, that adds a carboxyl group to a substrate, crucial in processes like photosynthesis (the Calvin cycle) and fatty acid synthesis.

  • Misspelling as 'carboxilation' (missing one 'y' sound).
  • Using it as a general term for any reaction with carboxylic acids.

FAQ

Frequently Asked Questions

No, they are completely different. Carbonation is the process of dissolving carbon dioxide in a liquid (like making fizzy drinks), while carboxylation is a chemical reaction adding a -COOH group.

The carboxylation of ribulose-1,5-bisphosphate by RuBisCO, which is the central CO2-fixing step in photosynthesis.

Yes, non-enzymatic carboxylation reactions exist in organic chemistry, often using strong bases and carbon dioxide, but biological carboxylations are typically enzyme-catalyzed.

The opposite reaction is decarboxylation, which is the removal of a carboxyl group (-COOH) as carbon dioxide (CO2).

The chemical process of introducing a carboxyl group (-COOH) into a molecule.

Carboxylation is usually technical/scientific in register.

Carboxylation: in British English it is pronounced /kɑːˌbɒksɪˈleɪʃən/, and in American English it is pronounced /kɑːrˌbɑːksɪˈleɪʃən/. Tap the audio buttons above to hear it.

Mnemonic

Think: CARBon + OXYgen + atION = the process of adding a group containing carbon and oxygen (COOH).

Conceptual Metaphor

A chemical 'stamp' or 'tagging' event, where a specific functional group is attached to a molecule.
