Removal of the COOH and its replacement with a proton.
The noun DECARBOXYLASE has 1 sense: 1. any of the enzymes that hydrolize the carboxyl group. Familiarity information: DECARBOXYLASE used as a noun is very rare.  THE DECARBOXYLATION OF CARBOXYLIC ACIDS AND THEIR SALTS This page looks at the formation of hydrocarbons by the decarboxylation of the salts of carboxylic acids (and of certain acids themselves) by heating them with soda lime. It does NOT cover the decarboxylation of some acids by simply heating them. Decarboxylation using soda lime. The solid sodium salt of a carboxylic acid is mixed with solid soda lime, and the mixture is heated. For example, if you heat sodium ethanoate with soda lime, you get methane gas formed: This reaction can be done with certain carboxylic acids themselves. 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. Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide (CO 2). Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain. Decarboxylation of aryl carboxylates can generate the equivalent of the corresponding aryl anion, which in turn can undergo cross coupling reactions. Alkylcarboxylic acids and their salts do not always undergo decarboxylation readily. By CannabisChris on. Decarboxylation of the cannabis plant is necessary to bring out the most of the THC by converting THC(a), which is non-psychoactive, into THC which is our favorite cannabinoid. Cannabis decarboxylation. Decarboxylation of the cannabis plant is necessary to bring out the most of the THC by converting THC(a), which is non-psychoactive, into THC which is our favorite cannabinoid. In organic chemistry [edit]. The term decarboxylation literally means removal of the COOH (carboxyl group) and its replacement with a proton. The term simply relates the state of the reactant and product. Decarboxylation of aryl carboxylates can generate the equivalent of the corresponding aryl anion, which in turn can undergo cross coupling reactions. Alkylcarboxylic acids and their salts do not always undergo decarboxylation readily. This “high” is from the cannabinoid THC, of which little if any is found when cannabis is growing or recently harvested. Decarboxylation is a chemical reaction that releases carbon dioxide (CO 2). This means a chemical reaction takes place in which carboxylic acids loose a carbon atom from a carbon chain. This process converts THCA to THC, the much loved compound with many medicinal and psychoactive effects.
