Initially discovered in the 1970s, the C21 steroidal acids α-cortolic acid, β-cortolic acid, α-cortolonic acid and β-cortolonic acid present the terminal oxidative products of cortisol metabolism. Undergoing renal elimination, these cortoic acids have been assumed to represent up to 25% of total urinary cortisol metabolites. However, their analysis has been difficult, only few data has been published in adults, and this class of steroids has beco...

Bile acids (BA) are C24 steroids synthesized from cholesterol in liver. Originally, they were mainly considered to function as emulsifiers supporting resorption of lipophilic food compounds and excretion of metabolic products. Recently, their additional biological and endocrine functions in the regulation of metabolism have aroused interest of researchers. In contrast to BA in blood, it is surprising that hardly any data exist on BA in the most accessible human biof...
