| Diet and lifestyle factors may be important in determining the ratio of estrogen metabolites. |
| Traditional toxicology screens that employ thin-layer chromatography can detect MDMA metabolites in the urine. |
| The plasma membrane transport of other metabolites such as amino acids and sugars can also be assayed by the changes in membrane potential. |
| The liver plays an essential role in the metabolism of bilirubin and the excretion of its metabolites into the bile. |
| This biogenetic hypothesis indicates an alternative pathway to produce these metabolites, leading to a new class of indole alkaloids. |
| The biosynthesis of many important primary metabolites proceed through intermediates that contain the allyl alcohol functional group. |
