Beta-keto acid decarboxylation is a key metabolic reaction that catalyzes the removal of carbon dioxide from beta-keto acids. This reaction is catalyzed by the enzyme beta-keto acid decarboxylase (KDC), a thiamine pyrophosphate (TPP)-dependent enzyme. TPP is a cofactor that binds to the enzyme and facilitates the decarboxylation process. Beta-keto acid decarboxylation is an essential step in the metabolism of amino acids and fatty acids, as well as the synthesis of certain vitamins and hormones.
