Ergosterol
Ergosterol is a phytosterol consisting of ergostane having double bonds at the 5,6-, 7,8- and 22,23-positions as well as a 3beta-hydroxy group. It has a role as a fungal metabolite and a Saccharomyces cerevisiae metabolite. It is a 3beta-sterol, an ergostanoid, a 3beta-hydroxy-Delta(5)-steroid and a member of phytosterols. A steroid of interest both because its biosynthesis in FUNGI is a target of ANTIFUNGAL AGENTS, notably AZOLES, and because when it is present in SKIN of animals, ULTRAVIOLET RAYS break a bond to result in ERGOCALCIFEROL. Ergosterol is a natural product found in Gladiolus italicus, Ramaria formosa, and other organisms with data available. ergosterol is a metabolite found in or produced by Saccharomyces cerevisiae. A steroid occurring in FUNGI. Irradiation with ULTRAVIOLET RAYS results in formation of ERGOCALCIFEROL (vitamin D2). See also: Reishi (part of). Ergosterol, also known as provitamin D2, belongs to the class of organic compounds known as ergosterols and derivatives. These are steroids containing ergosta-5,7,22-trien-3beta-ol or a derivative thereof, which is based on the 3beta-hydroxylated ergostane skeleton. Thus, ergosterol is considered to be a sterol lipid molecule. Ergosterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Ergosterol is the biological precursor to vitamin D2. It is turned into viosterol by ultraviolet light, and is then converted into ergocalciferol, which is a form of vitamin D. Ergosterol is a component of fungal cell membranes, serving the same function that cholesterol serves in animal cells. Ergosterol is not found in mammalian cell membranes. A phytosterol consisting of ergostane having double bonds at the 5,6-, 7,8- and 22,23-positions as well as a 3beta-hydroxy group. Ergosterol. CAS Common Chemistry.

Campesterol
Campesterol is a phytosterol, meaning it is a steroid derived from plants. As a food additive, phytosterols have cholesterol-lowering properties (reducing cholesterol absorption in intestines), and may act in cancer prevention. Phytosterols naturally occur in small amount in vegetable oils, especially soybean oil. One such phytosterol complex, isolated from vegetable oil, is cholestatin, composed of campesterol, stigmasterol, and brassicasterol, and is marketed as a dietary supplement. Sterols can reduce cholesterol in human subjects by up to 15\\\\\%. The mechanism behind phytosterols and the lowering of cholesterol occurs as follows : the incorporation of cholesterol into micelles in the gastrointestinal tract is inhibited, decreasing the overall amount of cholesterol absorbed. This may in turn help to control body total cholesterol levels, as well as modify HDL, LDL and TAG levels. Many margarines, butters, breakfast cereals and spreads are now enriched with phytosterols and marketed towards people with high cholesterol and a wish to lower it. -- Wikipedia. Campesterol is a member of phytosterols, a 3beta-sterol, a 3beta-hydroxy-Delta(5)-steroid and a C28-steroid. It has a role as a mouse metabolite. It derives from a hydride of a campestane.
