Decarboxylation Reaction – Definition, Reaction Mechanism and FAQs
Decarboxylation is a process in which carboxylic acids remove a carbon atom from a carbon chain. Carboxylation is the split chemical step in photosynthesis, where. C O 2. is added to the substance. It is a completely reversible reaction. Decarboxylases, on the other hand, are enzymes that catalyze decarboxylation.
Decarboxylation is often assumed to proceed from the carboxylate through a unimolecular dissociative process that gives a residual carbanion and CO 2. 2 This reaction would not be subject to general acid or base catalysis, as there are no feasible roles for these catalysts in the transition state for decarboxylation. Therefore, any observed acid or base catalysis in a …
