Detailed explanation-1: -Loss of carbon dioxide is called decarboxylation. Esters or carboxylic acids with a carbonyl group at the 3-(or b-) position readily undergo thermal decarboxylation. Decarboxylation was first encountered in Chapter 19 for carboxylic acids (review). The reactive species is the carboxylic acid or the carboxylate anion.

Detailed explanation-2: -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.

Detailed explanation-3: -Pyruvate decarboxylation or pyruvate oxidation, also known as the link reaction, Swanson Conversion, or oxidative decarboxylation of pyruvate, is the conversion of pyruvate into acetyl-CoA by the enzyme complex pyruvate dehydrogenase complex.

Detailed explanation-4: -Pyruvate decarboxylase is an enzyme (EC 4.1. 1.1) that catalyses the decarboxylation of pyruvic acid to acetaldehyde. It is also called 2-oxo-acid carboxylase, alpha-ketoacid carboxylase, and pyruvic decarboxylase.
