Table 1: Formulas for enzyme activity ratios. The formulas are derived from previous calculations, dividing the substrate concentrations by product concentrations, which correlate inversely with enzyme activity in 3ß-HSD.
| 3ß-HSD | DHEA*100/THE + α-CL + ß-CL |
| 11ß-HSD | ∑11-hydroxy-metabolites/∑11-keto-metabolites |
