Sterane

Index Sterane

Steranes constitute a class of tetracyclic triterpanes derived from steroids or sterols via diagenetic and catagenetic degradation, such as hydrogenation. [1]

Aldosterone

Aldosterone is the main mineralocorticoid steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland.

See Sterane and Aldosterone

Algae

Algae (alga) are any of a large and diverse group of photosynthetic, eukaryotic organisms.

See Sterane and Algae

Androstane

Androstane is a C19 steroidal hydrocarbon with a gonane core.

See Sterane and Androstane

Animal

Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia.

See Sterane and Animal

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.

See Sterane and Biosignature

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.

See Sterane and Cholestane

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.

See Sterane and Cholesterol

Clastic rock

Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock.

See Sterane and Clastic rock

Cortisol

Cortisol is a steroid hormone in the glucocorticoid class of hormones and a stress hormone. Sterane and Cortisol are steroids.

See Sterane and Cortisol

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.

See Sterane and Diagenesis

Embryophyte

The embryophytes are a clade of plants, also known as Embryophyta or land plants.

See Sterane and Embryophyte

Eukaryote

The eukaryotes constitute the domain of Eukarya or Eukaryota, organisms whose cells have a membrane-bound nucleus.

See Sterane and Eukaryote

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.

See Sterane and Gonane

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.

See Sterane and Hydrogenation

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.

See Sterane and Progesterone

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.

See Sterane and Proterozoic

Squalene

Squalene is an organic compound.

See Sterane and Squalene

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.

See Sterane and Steroid

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.

See Sterane and Sterol

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.

See Sterane and Stigmasterol

Testosterone

Testosterone is the primary male sex hormone and androgen in males.

See Sterane and Testosterone

Tetracyclic

Tetracyclics are cyclic chemical compounds that contain four fused rings of atoms, for example, Tröger's base.

See Sterane and Tetracyclic

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.
