Decarboxylation. Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide. Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain.The reverse process, which is the first chemical step in photosynthesis, is called carboxylation, the addition of CO2 to a compound.Enzymes that catalyze decarboxylations are called decarboxylases or, the more formal term, carboxy-lyases.he reverse process, which is the first chemical step in photosynthesis, is called carboxylation, the addition of CO2 to a compound.
