释义

Definition of decarboxylate in English:

decarboxylate

verb ˌdiːkɑːˈbɒksɪleɪtˌdikɑrˈbɑksəleɪt
[with object]Chemistry
  • 1Eliminate a carboxylic acid group from (an organic compound)

    heating at 100°C in dryness decarboxylates the proteins to yield glutamic acid
    Example sentencesExamples
    • Thus, malate produced following PEP carboxylation is readily decarboxylated and the CO 2 released.
    • Coproporphyrinogen III is transported to the interior of the mitochondrion, where 2 propionate residues are decarboxylated, yielding vinyl substituents on the 2 pyrrole rings.
    • In this compartment, called the matrix, the pyruvic acid is decarboxylated to a two-carbon acetyl group, releasing a CO 2 molecule, and is enzymatically joined to Coenzyme A, a large carrier molecule.
    • Pyruvate is first decarboxylated to produce acetaldehyde and carbon dioxide, catalyzed by pyruvate decarboxylase.
    • Malate formed by PEPC can either be used in the citric acid cycle or it can be decarboxylated to provide pyruvate and subsequently acetyl-CoA.
    1. 1.1no object Undergo the process of decarboxylation.
      unstable carbamic acid decarboxylates to yield the amine
      Example sentencesExamples
      • After electron transfer the product decarboxylates resulting in a ketylbiradical III that has a life time of about 4 s, long enough to reduce oxygen to superoxide.

Derivatives

  • decarboxylation

  • noun ˌdiːkɑːbɒksɪˈleɪʃ(ə)nˌdiˌkɑrbɑksəˈleɪʃ(ə)n
    Chemistry
    • The synthesis of serotonin is a two-step process involving a hydroxylation reaction catalyzed by the enzyme tryptophan - 5-monooxygenase and then a decarboxylation catalyzed by l-amino acid decarboxylase.
      Example sentencesExamples
      • Acetoacetate can undergo spontaneous decarboxylation to acetone, or be enzymatically converted to b-hydroxybutyrate through the action of b-hydroxybutyrate dehydrogenase.
      • An analogous electron transfer mechanism has been ascribed to the observed decarboxylation of a glutamic acid residue in the green fluorescent protein that results in the generation of free CO2 molecules.
      • Other sources of CO 2, unrelated to photorespiration and mitochondrial respiration but probably depending on decarboxylation of PEP metabolites, may be active at elevated CO 2.
      • A major source of ammonium, especially in C 3 plants, arises in the mitochondria from the decarboxylation of glycine to serine by the glycine decarboxylase as part of the photorespiratory cycle.
