Please refer to results attached as background material below.
Mean Water solubilty = <0.0064 g/L
Mean n-Octanol water solubility = 0.091 g/L
Calculation of Pow = 0.091/<0.0064
= < 14.22
Applicant's summary and conclusion
- Conclusions:
- The Pow for Escherichia coli dehalogenase enzyme was determined to be <14.22 (log Pow <1.15) using the solubility method.
- Executive summary:
The Pow for Escherichia coli dehalogenase enzyme was determined to be <14.22 (log Pow <1.15) using the solubility method.
