3-Methyltriaromatic steroids in sediments. Molecular fossils with unknown precursors

Résumé

The discovery of novel fossil substances can lead to the discovery of yet unknown modern biological substances such as bacterial hopanols. Here we discuss the origin and formation of some steroids found in petroleum and deep sediments. The occurrence of 3-methyl-triaromatic steroids, 3-methyl-steranes and 3-carboxy-steranes in sediments and petroleum suggest the presence of yet unidentified steroid precursors in biological organisms.
