Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The key study indicates that L-glutamine is readily biodegradable.
The supporting studies also indicate that L-glutamine is readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
In a GLP guideline study according to OECD 301 C L-glutamine showed to be readily biodegradable.
The GLP guideline study was considered the most reliable in comparison to the other available studies. Thus, it was chosen as the key study.
The experimental results of the supporting studies consistently indicate that L-glutamine is readily biodegradable.
One supporting study shows that L-glutamine is rapidly oxidized in activated sludge. After only 24 h already more than 30% of the Theoretical Oxygen Demand were achieved.The other supporting study was considered to be less reliable, because the documentation was insufficient.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
