单词	decarboxylate
释义	decarboxylate /ˌdiːkɑːˈbɒksɪleɪt / verb [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... Coproporphyrinogen III is transported to the interior of the mitochondrion, where 2 propionate residues are decarboxylated, yielding vinyl substituents on the 2 pyrrole rings. Thus, malate produced following PEP carboxylation is readily decarboxylated and the CO 2 released. 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. 1.1 [no object] Undergo the process of decarboxylation: unstable carbamic acid decarboxylates to yield the amine... 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 /ˌdiːkɑːbɒksɪˈleɪʃ(ə)n / noun ... 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. 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. Acetoacetate can undergo spontaneous decarboxylation to acetone, or be enzymatically converted to b-hydroxybutyrate through the action of b-hydroxybutyrate dehydrogenase.
