Steroid structures have perhydrocyclopentanophenanthrene nuclei comprising four rings (A, B, C and D), as represented by the structure of testosterone (Fig.
For the first applied technique (UV irradiation sterilization) we can suggest degradation of steroid nucleus (saturated tetracyclic hydrocarbon perhydrocyclopentanophenanthrene) which exists in chemical structure of tested compounds.
The main source of measured carbon radicals may be the methyl groups presented in perhydrocyclopentanophenanthrene. Similar mechanism for the formation of carbon radicals in both bile acids (connected probably with the degradation of their perhydrocyclopentanophenanthrene ring) could be expected in the case of thermal sterilization of examined steroid compounds.
