In this video we are going to study Decarboxylation reactions By:- K.K Singh what is Decarboxylation reactions Decarboxylation reaction is defined as a chemical reaction that eliminates a carboxyl group and liberates carbon dioxide (CO2). Decarboxylation mostly refers to a reaction of carboxylic acids erasing a carbon atom from a chain of carbons. Carboxylation is a completely reversible process which is the first chemical step in photosynthesis, where CO2 is added to the compound. Whereas, Enzymes that catalyse decarboxylation are known as decarboxylases. Metabolic context of Carboxylation and Decarboxylation The most important carbon-carbon bond forming and breaking in biological chemistry encompasses gain or loss of a single carbon by an organic molecule in the form of CO2. You must have seen an equation like this in one of the introductory biology class. 6CO2 + 6H2O + energy → C6H12O6 + 6O2 It describes the photosynthetic process by which plants harness energy from sunlight to produce glucose from individual molecules of carbon dioxide. The main step wherein the carbon dioxide is fixed (condensed with an organic molecule) is known as carboxylation reaction. You must also be familiar with the reverse chemical equation: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy The above chemical reaction describes what occurs in respiration, i.e, the oxidative breakdown of glucose to form water, carbon dioxide, and energy. Every carbon atom of glucose is converted into CO2 molecules in the course of transformation. The main step where a carbon atom breaks off from a larger organic molecule is known as decarboxylation reaction. The major decarboxylation stage in the conversion of glucose to carbon dioxide takes place in the citric acid cycle and the pentose phosphate pathway. video edited and recorded by Studyfication Pvt.Ltd Email:- [email protected] @studyfication Contact no:- 8887899506 https://bit.ly/2AjAbEr
