carboxylate

8.7
A negative ion formed when a carboxylic acid loses a hydrogen
  • noun
  • /kɑrˈbɑksɪleɪt/
  • Specialized
translation icon : carboxilato
  • The carboxylate group plays a crucial role in forming complexes with other molecules.
  • carboxylate ligands
  • carboxylate shift
  • carboxylate rearrangement

Examples

  • Our studies indicate that this process occurs with a large activation barrier if during the reaction all Fe-O (bridging carboxylate) bonds remain intact.

  • We also have this carboxylate group, which we also have here.

  • Or if you have an extra electron on it and you have the carboxylate anion, then again, it's just one species, a single minimum, right?

  • Which is more stabilized, the carboxylate or the original alcohol, the carboxylic acid?

  • Thus, the data described above clearly show that the ubiquitous carboxylate ligands (glutamates and aspartates) of MMOH and R2 may play a special role in the proper functioning of these enzymes.

  • The researchers measured the stability of the carboxylate ion formed when the acid dissociated.

  • In the experiment, the carboxylate was shown to effectively interact with metal ions.

Surface Forms

carboxylate singular
carboxylates plural

Morphology

carboxylate = carboxyl (transparent) = carboxyl + ate

The noun is the standard chemical '-ate' form of 'carboxyl', denoting the deprotonated ion or its salts; morphology is regular within chemical nomenclature.

Etymology

Carboxylate joins carboxyl ('carbon' + 'oxygen') with the ending -ate, which often names a salt or negative ion (think carbonate). A carboxylate is the ion you get when a carboxyl 'acid' loses a hydrogen, so it carries a negative charge.
