Popis:	The mode of attachment of steroid moieties to a nonpolar macromolecular fraction (NPMF) of Rozel Point seep oil has been studied by selective chemical and thermal degradation procedures. The former comprised hydrogenolysis of C-S bonds with deuterated Raney nickel, cleavage of S-S bonds with lithium aluminum hydride, and thermal cleavage of S-S bonds. GC-MS study of the degradation products showed that sterane molecules formed in high concentration were essentially attached to the macromolecular networks by one linkage located in ring A or B
