| Sumario: | The free sterols of the snail, Biomphalaria tenagophila, were isolated and characterized by means of gas chromatography and gas chromatography-mass spectrometry techniques. The mixture contains the common steroids found in freshwater molluscs, principally cholesterol. The presence of cholesta-5,7-dien-3β-ol is without precedent in freshwater organisms. The occurrence of 7-oxo-cholesterol in freshwater snails, but not bivalves, from the same freshwater source, would indicate a difference in the physiology of such snails and bivalves. © 1984 American Oil Chemists' Society. |
