11-Oxo etiocholanolone  (Synonyms: 11-Ketoetiocholanolone)

11-Oxo etiocholanolone (11-Ketoetiocholanolone) is a steroid. 11-Oxo etiocholanolone is a key indicator for detecting cortisol metabolites in feces and urine. 11-Oxo etiocholanolone has the potential to be a pheromone^[1][2][3].

11-Oxo-etiocholanolone is a steroid present in reproductively mature male round gobies. It is released into the water by male round gobies in free and various conjugated forms upon stimulation by a salmon gonadotropin-releasing hormone analogue^[2].
