Results and discussion

Remarks on result:
not measured/tested

Any other information on results incl. tables

The query structure does not match any structural alerts or examples for (bacterial in vitro) mutagenicity in Derek. Additionally, the query structure does not contain any unclassified or misclassified features and is consequently predicted to be inactive in the bacterial in vitro (Ames) mutagenicity test.

Applicant's summary and conclusion

Conclusions:
The query structure does not match any structural alerts or examples for (bacterial in vitro) mutagenicity in Derek. Additionally, the query structure does not contain any unclassified or misclassified features and is consequently predicted to be inactive in the bacterial in vitro (Ames) mutagenicity test.
Dehydrocholic acid does not satisfy the CLP criteria for mutagenicity classification.
