Aldosterone
Aldosterone is the main mineralocorticoid steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland.
Algae
Algae (alga) are any of a large and diverse group of photosynthetic, eukaryotic organisms.
Androstane
Androstane is a C19 steroidal hydrocarbon with a gonane core.
Animal
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia.
Biosignature
A biosignature (sometimes called chemical fossil or molecular fossil) is any substance, such as an element, isotope, molecule, or phenomenon, that provides scientific evidence of past or present life on a planet.
Catagenesis (geology)
Catagenesis is a term used in petroleum geology to describe the cracking process which results in the conversion of organic kerogens into hydrocarbons.
See Sterane and Catagenesis (geology)
Cholestane
Cholestane is a saturated tetracyclic triterpene. Sterane and Cholestane are Cholestanes.
Cholesterol
Cholesterol is the principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. Sterane and Cholesterol are Cholestanes.
Clastic rock
Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock.
Cortisol
Cortisol is a steroid hormone in the glucocorticoid class of hormones and a stress hormone. Sterane and Cortisol are steroids.
Diagenesis
Diagenesis is the process that describes physical and chemical changes in sediments first caused by water-rock interactions, microbial activity, and compaction after their deposition.
Embryophyte
The embryophytes are a clade of plants, also known as Embryophyta or land plants.
Eukaryote
The eukaryotes constitute the domain of Eukarya or Eukaryota, organisms whose cells have a membrane-bound nucleus.
Gonane
Gonane (cyclopentanoperhydrophenanthrene) is a chemical compound with formula, whose structure consists of four hydrocarbon rings fused together: three cyclohexane units and one cyclopentane. Sterane and Gonane are steroid stubs and steroids.
Hydrogenation
Hydrogenation is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum.
Oil
An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) and lipophilic (mixes with other oils).
See Sterane and Oil
Oxidosqualene cyclase
Oxidosqualene cyclases (OSC) are enzymes involved in cyclization reactions of 2,3-oxidosqualene to form sterols or triterpenes.
See Sterane and Oxidosqualene cyclase
Progesterone
Progesterone (P4) is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species.
Proterozoic
The Proterozoic is the third of the four geologic eons of Earth's history, spanning the time interval from 2500 to 538.8Mya, the longest eon of the Earth's geologic time scale.
Squalene
Squalene is an organic compound.
Steroid
A steroid is an organic compound with four fused rings (designated A, B, C, and D) arranged in a specific molecular configuration. Sterane and steroid are steroids.
Sterol
Sterol is an organic compound with formula, whose molecule is derived from that of gonane by replacement of a hydrogen atom on C3 position by a hydroxyl group.
Stigmasterol
Stigmasterol – a plant sterol (phytosterol) – is among the most abundant of plant sterols, having a major function to maintain the structure and physiology of cell membranes.
Testosterone
Testosterone is the primary male sex hormone and androgen in males.
Tetracyclic
Tetracyclics are cyclic chemical compounds that contain four fused rings of atoms, for example, Tröger's base.
Triterpene
Triterpenes are a class of terpenes composed of six isoprene units with the molecular formula C30H48; they may also be thought of as consisting of three terpene units.
