Gonan-3-ol, the simplest sterol. A sterol is any organic compound with a skeleton closely related to cholestan-3-ol. The simplest sterol is gonan-3-ol, which has a formula of C 17 H 28 O, and is derived from that of gonane by replacement of a hydrogen atom on C3 position by a hydroxyl group. It is therefore an alcohol of gonane. [1] [2] [3]
Ergosterol (ergosta-5,7,22-trien-3β-ol) is a sterol found in fungi, and named after ergot, the common name of members of the fungal genus Claviceps from which ergosterol was first isolated. Ergosterol is a component of yeast and other fungal cell membranes, serving many of the same functions that cholesterol serves in animal cells. [1]
Stigmasterol is a food additive in manufactured food products in the United Kingdom and European Union. [7]It was introduced as a precursor by Percy Lavon Julian for industrial large-scale manufacture of semisynthetic progesterone, [8] [9] [10] a valuable human hormone that plays an important physiological role in the regulatory and tissue rebuilding mechanisms related to estrogen effects, as ...

The molecular mechanisms regulating the absorption of dietary sterols in the body are poorly understood, and as sitosterolemia is a rare autosomal recessively inherited lipid metabolic disorder characterized by hyperabsorption and decreased biliary excretion of dietary sterols, studies have focused on the molecular basis of sitosterolemia to shed light on important principles concerning ...
Brassicasterol (24-methyl cholest-5,22-dien-3β-ol) is a 28-carbon sterol synthesised by several unicellular algae (phytoplankton) and some terrestrial plants, like rape.This compound has frequently been used as a biomarker for the presence of (marine) algal matter in the environment, and is one of the ingredients in stigmasterol-rich plant sterols (Number E499 in the European numbering system).
Sterol carrier proteins (also known as nonspecific lipid transfer proteins) is a family of proteins that transfer steroids and probably also phospholipids and gangliosides between cellular membranes. These proteins are different from plant nonspecific lipid transfer proteins but structurally similar to small proteins of unknown function from ...
The proteins encoded by this gene are transcription factors that bind to a sequence in the promoter of different genes, called sterol regulatory element-1 (SRE1). This element is a decamer (oligomer with ten subunits) flanking the LDL receptor gene and other genes involved in, for instance, sterol biosynthesis.
