Munich, Germany, 17-20 May 2002 A steroid is a biologically active organic compound with four rings arranged in a specific molecular configuration. Steroids have two principal biological functions: as important components of cell membranes which alter membrane fluidity; and as signaling molecules. Hundreds of steroids are found in plants, animals and fungi.They use the sterols (animal or plant) present in their food and are capable of meta­bolizing them to cholesterol, precursor of hormonal derivatives like ecdysone.

Steroid hormones are derivatives of cholesterol and therefore can pass through the plasma membrane of cells since they are lipophilic. Steroid hormones generally don't bind on the surface of plasma membranes, but instead to receptors inside the cell itself. Since they are nonpolar, they are carried by proteins in the blood.

Steroids with 21 carbon atoms are known systematically as pregnanes, whereas those containing 19 and 18 carbon atoms are known as androstanes and estranes, respectively. The subject "Biochemistry of Steroids" encompasses a wide range of topics as attested by the diversity of the papers presented at the Second In­ ternational Congress on Hormonal Steroids in Milan, 1966. Even in a rudi­ mentary manner, it would be impossible to discuss all aspects of this dynamic field in the space allotted. This subject was last reviewed by Talalay ( 1 ) in 1965, who ... Biochemistry of Steroids S Lieberman, and and K Dobriner Annual Review of Biochemistry Group-Specific Reagents in Protein Chemistry L A Cohen Annual Review of Biochemistry Biochemistry of Steroid Hormones Research in steroid biochemistry first began with studies on the biosynthesis and metabolism of steroids, followed soon thereafter by investigations on the biochemical mechanism of action of steroids. Over the past several decades, steroid biochemistry and molecular biology have focused on steroidogenic enzymes, nuclear steroid receptors, and ...The Chemistry of the Steroids W L Ruigh Annual Review of Biochemistry The Chemistry of the Proteins and Amino Acids G.
