In this article we will discuss about the process of biosynthesis of steroids, explained with the help of suitable diagrams. Biosynthesis of Cholesterol: The main steps of the biosynthesis of cholesterol are diagrammatically represented in figure 5-22. The first reaction consists of the condensation of 2 molecules of acetyl-coA. It is the reverse of the reaction which takes place during [...]
In this article we will discuss about the groups and useful roles of steroids. Groups of Steroids: Some of the major groups of steroids are as follows: 1. Sterols: Steroids with 8-10 carbon long aliphatic side chain at carbon 17 and at least one alcoholic hydroxyl (e.g., at position 3), e.g., cholesterol, ergasterol, coprosterol, stigmasterol, sitosterol, campesterol. 2. Bile Acids: [...]
