Decarboxylation of amino acid results in the formation of an Amine by the removal of the carboxyl group (-COOH) from the amino acid. Due to the removal of the organic acid group, the byproduct moves up the pH scale for being of alkaline nature. The decarboxylase enzymes facilitate the decarboxylation mechanism i.e. removal of acidic groups.

Decarboxylation begins with an internal acid-base reaction, where the acid is the O H unit of the carboxylic acid, and the base is the oxygen of the carbonyl β to the acid moiety. Decarboxylation is possible because of the facile loss of a neutral leaving group carbon dioxide.
