Figure 3. The stability of GSH. Panel A shows the 95th percentile (blue), the mean (green), and the 5th percentile (red) of estradiol during the menstrual cycle. The curves are drawn by interpolation of data from^[24,25]. Panel B shows the relative stability of GSH during the cycle (varying from 5,500 to 7,900 μM). This is true despite the wide range of steady state values [Table 1 and Figure 2A]. See the text for an explanation.
