CHEBI:86537 - Notes
- Original MicrobeDecoder label and BacDive term recovered during #710 review. All four original MicrobeDecoder source rows explicitly name 2,2-dimethylsuccinic acid. Their BacDive records identify CHEBI:86537. The historical 2,3-isomer CHEBI:167506 is rejected; this is a distinct constitutional isomer, not a close match. The raw truncated label is retained for source lookup; historical incorrect inference remains in curation history only.
