Carboxylation and Decarboxylation - an overview
WebDecarboxylation 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.The reverse process, which is the first chemical step in photosynthesis, is called carboxylation, the addition of CO 2 to a compound.

WebBCH3120 INTERMEDIARY METABOLISM: LECTURE 10 Formation of malonyl-CoA Step1 This is a carboxylation reaction A bicarbonate ion is loaded on the biotin prosthetic group attached to ACC (biotin carrier protein) The reaction is catalyzed by the biotin carboxylase activity of ACC and is driven by ATP hydrolysis 12 prosthetic group part of the enzyme ... Let us define a carboxylation reaction as the addition of a CO2 unit to a substrate molecule, and decarboxylation as loss of CO2. Decarboxylation reaction reactions are typically quite thermodynamically favorable due to the entropic contribution of cleaving a single molecule into two, one of which is a gas. Conversely, we can expect carboxylation reactions to be energy-requiring, and we should not be surprised to learn ATP hydrolysis is coupled to carboxylation.
