11. Two common decarboxylation products of protein associated with decomposition are putrescine and cadaverine. 12. JA undergoes decarboxylation to give cis-jasmone. 13. CBN is then formed by decarboxylation of CBNA. 14. Palladium ( II ) trifluoroacetate has been demonstrated to be effective in aromatic decarboxylation : 15. It is also generated biologically in small amounts apparently by decarboxylation of trifluoroacetic acid. 16. The glycidate then undergoes saponification followed by decarboxylation . 17. :Someone uploaded an image displaying the mechanism for the decarboxylation of a ketoacid. 18. Trying to restore a C = O results in decarboxylation . . . .? 19. The chain shortening could be produced by a beta-oxidation then a decarboxylation . 20. Biosynthesis begins with decarboxylation of ornithine by ornithine decarboxylase ( ODC ) to produce putrescine.
