Experimental Biology and Medicine, 1957 Summary1. Urinary bladders of many species were analyzed for cholesterol and “fast-acting” (δ7) sterol. Rodents showed the highest content of (δ7) sterol, the dog an intermediate level, and livestock very little. In rodents and in the dog 60-84% of the δ7-sterol was 7-dehydrocholesterol. All bladder sterol was unesterified. 2. The sterols were found to
