21. Muscimol is the product of the decarboxylation ( usually by drying ) of ibotenic acid. 22. Tryptophan is converted to tryptamine by decarboxylation . 23. The latter forms are unstable and are transformed, e . g . by decarboxylation . 24. Ornithine decarboxylase can catalyse the decarboxylation of DFMO instead of ornithine, as shown above. 25. Isocitrate dehydrogenases are enzymes that catalyze the oxidative decarboxylation of isocitrate to 2-oxoglutarate. 26. Its main function is to catalyze the oxidative decarboxylation of isocitrate into alpha-ketoglutarate. 27. Jasmone is produced by some plants by the metabolism of jasmonic acid, via a decarboxylation . 28. This creates a reactive intermediate, which in the second stage undergoes concerted dephosphorylation and decarboxylation . 29. Decarboxylation leads to tropane alkaloid formation.30. Cycloheptanone is still produced by the cyclization and decarboxylation of suberic acid or suberic acid esters.
