    • ‘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.’
    • ‘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. 1.1[no object]Undergo the process of decarboxylation.
      • ‘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.’
