Decarboxylation is a chemical reaction that removes a carboxyl group (-COOH) from a molecule, releasing it as carbon dioxide (CO2). This process is common in organic chemistry and plays significant roles in both biological and industrial settings. In organic synthesis, decarboxylation is often employed to simplify molecules or to prepare them for further reactions. The reaction typically requires heat, and the specific conditions depend on the structure of the carboxylic acid. Some common examples include the thermal decarboxylation of malonic acid derivatives, which leads to the formation of substituted acetic acids.

In biological systems, decarboxylation is crucial for metabolic pathways. For instance, the citric acid cycle (Krebs cycle) involves several decarboxylation steps, which are essential for cellular respiration and energy production. Amino acids also undergo decarboxylation to form important biomolecules, such as neurotransmitters (e.g., GABA from glutamic acid) and amines. Enzymes called decarboxylases catalyze these biological reactions, often allowing them to occur under milder conditions than uncatalyzed thermal decarboxylations. Industrially, decarboxylation is used in the production of various chemicals, including polymers and pharmaceuticals. For example, the production of certain types of nylon involves decarboxylation steps. The removal of the carboxyl group can alter the reactivity and physical properties of a compound, making it a versatile tool in chemistry.
