1. Hydrolysis of the decarboxylation product generates the D-amino acid. 2. One way that it can be produced by decarboxylation of aspirin. 3. Ornithine then undergoes a pyridoxal phosphate-dependent decarboxylation to form putrescine. 4. Hydrolysis of the methyl ester and decarboxylation leads to norfluorocurarine. 5. Carbon deletion occurs by way of a Favorskii rearrangement and subsequent decarboxylation . 6. It is formed when cystine is heated, the result of decarboxylation . 7. Its major role is the extraction of reducing equivalents by the decarboxylation . 8. The third box is Step 2, which is the decarboxylation of oxalosuccinate. 9. More specifically it is formed by the decarboxylation of the amino acid tyrosine. 10. Phosphosphomevalonate decarboxylase through a concerted decarboxylation reaction affords isopentenyl pyrophosphate ( IPP ).
