Definition of carboxylate in English:
carboxylate
noun kɑːˈbɒksɪleɪtkärˈbäksəˌlāt
Chemistry A salt or ester of a carboxylic acid.
Example sentencesExamples
- Alkaline earth metal ions more readily bind ‘hard’ ligands such as phosphates, carboxylates, and hydroxyl groups.
- What is more, the indicator has two proton-binding sites: the oxyanion of the xanthene ring and the carboxylate of the benzene as independent sites, which can also exchange protons among themselves.
- The Hill coefficient should distinguish between amides near an isolated carboxylate and amides interacting with multiple carboxylates.
- Such a low pH value suggests that at higher pH the protonation of a carboxylate, forming a hydrogen bond, would break this interaction leading to a destabilization and a change in the heme pocket crucial to catalysis.
- The ability to mine P is attributed to the development of specialized ‘proteoid’ or ‘cluster’ roots that exude large quantities of carboxylates and phosphatases.

[with object]Chemistry Add a carboxyl group to (a compound)
warfarin prevents vitamin K from carboxylating the vitamin K-dependent clotting factors
Example sentencesExamples
- It is suggested that mitochondrial pyruvate is partly oxidized by the TCA cycle and is partly exported to the cytoplasm where it is carboxylated to form malate 1-for continued export to the apoplast.
- The optically trapped carboxylated bead is attached to the cationic vesicle adhered onto a glass coverslip, by electrostatic interactions.
- Depending on ratios of CO 2 to O 2 at binding sites of ribulose bisphosphate carboxylase, ribulose bisphosphate is either carboxylated or oxygenated.
- As the name of the enzyme implies, pyruvate is carboxylated to form oxaloacetate.
- Lack of proton-pumping activity has also been found in heterologously expressed Neurospora rhodopsin, which has carboxylated residues at both the Schiff base proton donor and acceptor positions, as does GtR1.

Chemistry Thus, malate produced following PEP carboxylation is readily decarboxylated and the CO 2 released.
Example sentencesExamples
- Besides requiring vitamin K, these extrinsic factors need carbon dioxide and oxygen for carboxylation.
- The best-studied CAM models produce predominantly starch in the chloroplast as the transitory carbon reserve to support nocturnal carboxylation and malate synthesis.
- Rubisco must be activated to catalyse the carboxylation and oxygenation reactions.
- OAA would be produced by carboxylation of phosphoenol pyruvate in a reaction catalysed by guard cell PEP carboxylase.
