Steroid biosynthesis is an anabolic pathway which produces steroids from simple precursors. A unique biosynthetic pathway is followed in animals (compared to many other organisms ), making the pathway a common target for antibiotics and other anti-infection drugs. 查看更多內容 A steroid (named after the steroid cholesterol which was first described in gall stones from Ancient Greek chole- 'bile' and stereos 'solid' ) is a biologically active organic compound with four rings arranged in a specific 查看更多內容 In eukaryotes, steroids are found in fungi, animals, and plants. Fungal steroids Fungal steroids include the ergosterols, which are … 查看更多內容 Steroids and their metabolites often function as signalling molecules (the most notable examples are steroid hormones), and steroids and 查看更多內容 Steroids are primarily oxidized by cytochrome P450 oxidase enzymes, such as CYP3A4. These reactions introduce oxygen into the steroid ring, allowing the cholesterol to be … 查看更多內容 Gonane, also known as steran or cyclopentanoperhydrophenanthrene, the simplest steroid and the nucleus of all steroids and sterols, is composed of seventeen carbon atoms in carbon-carbon bonds forming four fused rings in a three-dimensional shape. … 查看更多內容 By function The major classes of steroid hormones, with prominent members and examples of related functions, are: • Corticosteroids: • Sex steroids: Additional … 查看更多內容 The hundreds of steroids found in animals, fungi, and plants are made from lanosterol (in animals and fungi; see examples above) or cycloartenol (in other eukaryotes). Both lanosterol and cycloartenol derive from cyclization of the triterpenoid 查看更多內容 網頁Nandrolone, also known as 19-nortestosterone, is an androgen and anabolic steroid (AAS) which is used in the form of esters such as nandrolone decanoate (brand name Deca-Durabolin) and nandrolone phenylpropionate (brand name Durabolin). Nandrolone esters are used in the treatment of anemias, cachexia (muscle wasting syndrome), …

網頁Steroidogenesis. Steroid hormones are derivatives of cholesterol that are synthesized by a variety of tissues, most prominently the adrenal gland and gonads. The cholesterol precursor comes from cholesterol synthesized within the cell from acetate, from cholesterol ester stores in intracellular lipid droplets or from uptake of cholesterol ... 網頁Prednisone is a glucocorticoid medication mostly used to suppress the immune system and decrease inflammation in conditions such as asthma, COPD, and rheumatologic diseases. [2] It is also used to treat high blood calcium due to cancer and adrenal insufficiency along with other steroids.
