Steranes constitute a group of alkane organic compounds with a cyclopentane -fused hydrogenated phenanthrene structure as the parent nucleus, and they derived from steroids or sterols via diagenetic and catagenetic degradation, such as hydrogenation. They are found in sediments and sedimentary rocks in nature. [1] .

Oct 28, 2022 · Within the sterane pool we detect a trend toward aromatization of steroidal compounds within hotter sediments. The changes in hopane and sterane biomarker composition at different sites reflect...

Steroids are lipophilic molecules consisting of four interconnected carbon rings, the so-called cyclopentanoperhydrophenanthrene rings, also known as sterane. You might find these chapters and articles relevant to this topic.

Oct 15, 2018 · Here, we report a new fossil sterane biomarker that co-occurs with 24-ipc in a suite of late Neoproterozoic–Cambrian sedimentary rocks and oils, which possesses a rare …

Steroids, a class of triterpenoid lipids with high preservation potential, are widely distributed in sedimentary rocks. All eukaryotes have a physiological requirement for these molecules, making steroids important biomarkers for aiding our understanding of eukaryote molecular evolution and geologic history.

The term alphabetabeta sterane (sometimes just alphabeta) is commonly used as short-hand to denote steranes with the 5alpha (H), 14beta (H), 17beta (H) configuration, while alphaalphaalpha sterane would denote 5alpha (H), 14alpha (H), 17alpha (H) stereochemistry.

Jun 11, 2021 · Steranes is a class of four-ringed cyclic compounds derived from steroids or sterols via diagenetic degradation and thermal maturation. The sterane structure is fully saturated with hydrogen atoms (Fig. 1) and makes up the hydrocarbon core of all steroids and sterols.

The characteristic structure of a sterane molecule, a biomarker. Living organisms possess exclusively one type of sterols, but during diagenesis and catagenesis, steranes are gradually transformed, until an equilibrium is reached.

The hypothetic parent molecule for any steroid hormone; a saturated hydrocarbon compound that contains no oxygen.
