Steroids

    Steroids are a class of organic compounds belonging to the chemical nature of isoprenoids. 

Different types of Steroids  widespread in nature and are found in microorganisms, plants and animals, one of the main chemical evolution C. - their specialization as biological controls - hormones, etc.

    All Steroids  formally derive hypothetical hydrocarbon steranes (I, R = H), and biogenetic come from squalene, which is converted in the next polycyclic precursor Steroids. - lanosterol (in animals) or cycloartenol (plants), containing 30 carbon atoms (S30 ).  


    Almost all Steroids are - crystalline substances with optical activity and better soluble in organic solvents than in water.
