Steroids from aquatic organisms-XI. Steroid composition of the prosobranch mollusc Patinigera magellanica
1. 1. Freshly frozen soft tissue of the prosobranch mollusc Patinigera magellanica, collected at South Atlantic waters in Argentina, during the intertidal period, contained a mixture of common C27, C28 and C29 sterols where cholesterol was the major component. 2. 2. Besides them, oxygenated Δ5-7-ket...
