Each numerical entry represents the relative abundance (percentage) of all GSH conjugates combined that were formed via conjugate addition during the reaction of the compound listed at left
The values were estimated based on the ratio of UV peak areas of the GSH conjugates detected following 30 minutes of incubation to that of the respective parent compound at 0 minute. The values represent the mean of the duplicate measurements for each of the incubations.
