Metabolite Card

Note

Androsterone glucuronide (ADT-G) is one of the major circulating C19-steroid metabolites in humans. Human and monkey are unique in having high levels of circulating ADT-G. Furthermore, the plasma levels of these glucuronide derivatives reflect the peripheral tissue conversion of adrenal and gonadal precursor C19-steroids to active androgens in various pathophysiological conditions. Identification and characterization of human UDP-glucuronosyltransferase 2B (UGT2Bs) demonstrated the major role that these enzymes play in androgen conjugation, with UGT2B15 and UGT2B17 (EC 2.4.1.17) being the major androsterone-conjugating isoforms. Exaggerated androsterone metabolism, is observed in hyper-androgenic as well as in some normo-androgenic women with acne and androsterone glucuronide could be a marker in differentiating acne and hirsutism in hyperandrogenic women. Present data shows that the most practical and probably only valid means of assessing androgenic activity in women is to measure ADT-G, the metabolite that accounts for 93% of the total androgen glucuronide derivatives.
