Abstract
1. Cholesterol content of selected tissues in the Saudi frog Rana ridibunda was determined. 2. Total cholesterol content was higher in tissues involved in water loss, ranging from 12.22 +/- 0.28 to 40.3 +/- 0.79 mg/g. 3. In tissues not involved in water loss, total cholesterol content ranged from 2.42 +/- 0.18 to 19.30 +/- 0.39 mg/g.
