Ergocalciferol
Ergocalciferol appears as odorless white crystals. Used as a dietary supplement and food additive. (EPA, 1998) Vitamin D2 is a vitamin D supplement and has been isolated from alfalfa. It has a role as a nutraceutical, a bone density conservation agent, a rodenticide and a plant metabolite. It is a seco-ergostane, a hydroxy seco-steroid and a vitamin D. Ergocalciferol is an inactivated vitamin D analog. It is synthesized by some plants in the presence of UVB light. The production of ergocalciferol was prompted by the identification of dietary deficiency, more specifically vitamin D, as the main causative factor for the development of rickets. Ergocalciferol was isolated for the first time from yeast in 1931 and its structure was elucidated in 1932. Ergocalciferol is considered the first vitamin D analog and is differentiated from [cholecalciferol] by the presence of a double bond between C22 and C23 and the presence of a methyl group at C24. These modifications reduce the affinity of ergocalciferol for the vitamin D binding protein resulting in faster clearance, limits its activation, and alters its catabolism. The first approved product containing ergocalciferol under the FDA records was developed by US Pharm Holdings and was FDA approved in 1941. Ergocalciferol is a Provitamin D2 Compound. Ergocalciferol is a natural product found in Pseudo-nitzschia multistriata, Humulus lupulus, and other organisms with data available. Ergocalciferol is vitamin D2, a fat-soluble vitamin important for many biochemical processes including the absorption and metabolism of calcium and phosphorus. In vivo, ergocalciferol is formed after sun (ultraviolet) irradiation of plant-derived ergosterol, another form of vitamin D. Ergocalciferol is the form of vitamin D usually found in vitamin supplements. (NCI04) Ergocalciferol is a form of Vitamin D, also called vitamin D2. It is created from viosterol, which in turn is created when ultraviolet light activates ergosterol. Ergocalciferol is used in the treatment of hypcalcemia and in dialysis-dependent renal failure. Ergoalcifediol is a fat soluble steroid hormone precursor of vitamin D that contributes to the maintenance of normal levels of calcium and phosphorus in the bloodstream. Vitamin D2 is the form of vitamin D most commonly added to foods and nutritional supplements. Vitamin D2 must be transformed (hydroxylated) into one of two active forms via the liver or kidney. Once transformed, it binds to the vitamin D receptor that then leads to a variety of regulatory roles. Derivatives of ERGOSTEROL formed by ULTRAVIOLET RAYS breaking of the C9-C10 bond. They differ from CHOLECALCIFEROL in having a double bond between C22 and C23 and a methyl group at C24. See also: ... View More ... Ergocalciferol is a form of Vitamin D, also called vitamin D2.

24-Methylenecholesterol
24-Methylenecholesterol, also known as chalinasterol or ostreasterol, 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, 24-methylenecholesterol is considered to be a sterol lipid molecule. 24-Methylenecholesterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 24-Methylenecholesterol is involved in the biosynthesis of steroids. 24-Methylenecholesterol is converted from 5-dehydroepisterol by 7-dehydrocholesterol reductase (EC 1.3.1.21). 24-Methylenecholesterol is converted into campesterol by delta24-sterol reductase (EC 1.3.1.72). 24-methylenecholesterol is a 3beta-sterol having the structure of cholesterol with a methylene group at C-24. It has a role as a mouse metabolite. It is a 3beta-sterol and a 3beta-hydroxy-Delta(5)-steroid. It is functionally related to a cholesterol. 24-Methylenecholesterol is a natural product found in Echinometra lucunter, Ulva fasciata, and other organisms with data available. A 3beta-sterol having the structure of cholesterol with a methylene group at C-24. Constituent of clams and oysters 24-Methylenecholesterol (Ostreasterol), a natural marine sterol, stimulates cholesterol acyltransferase in human macrophages. 24-Methylenecholesterol possess anti-aging effects in yeast. 24-methylenecholesterol enhances honey bee longevity and improves nurse bee physiology[1][2][3].
5-Dehydroepisterol
5-Dehydroepisterol 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, 5-dehydroepisterol is considered to be a sterol lipid molecule. 5-Dehydroepisterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 5-Dehydroepisterol is an intermediate in the biosynthesis of steroids and is converted from episterol via the enzyme lathosterol oxidase (EC 1.14.21.6). It is then converted into 24-methylenecholesterol via the enzyme 7-dehydrocholesterol reductase (EC 1.3.1.21). 5-Dehydroepisterol is an intermediate in the biosynthesis of steroids (KEGG ID C15780), and is converted from Episterol via the enzyme lathosterol oxidase [EC:1.14.21.6].
