Decarboxylation is a chemical reaction that involves the removal of a carboxyl group from a molecule, resulting in the release of carbon dioxide CO2. This process is essential in various biological and chemical pathways, including the metabolism of amino acids and the conversion of cannabinoids in cannabis. In the context of cooking, decarboxylation is often discussed regarding the preparation of cannabis for edibles. When cannabis is heated, the inactive compound THCA is converted into the psychoactive compound THC, enhancing its effects when consumed.
